Abstract:

Despite the implementation and good coverage of the WHO recommended malaria control program IRS, malaria continues to be a very serious public health challenge in upper west region compared to other regions of Ghana. We explored enablers and barriers of community uptake of this program in a highly malaria endemic region in Ghana. Between April and October, 2016 we conducted a qualitative inquiry, focus group discussion and semi-structured interviews with program stakeholders. Participants included community members, program operators and health system officials in upper western Ghana. 105 participants were involved in the study. Findings identified significant barriers to program uptake by communities including religious beliefs, superstition, and and fear of insecticides among others.  Enablers of program uptake by the communities included malaria prevention, efficacy of intervention, and incidental benefits. Program providers and health system officials detailed the following as a necessity to improve implementation: effective collaboration between stakeholders and the need to intensify public education. Despite challenges from both the program recipient and operator ends, IRS is an accepted intervention in the region. In order to improve the uptake and effective implementation, strategies to improve community uptake and streamline operations will be needed. These findings have policy and practice significance to improve community uptake and service operations of this novel public health intervention.

Abstract:

Viruses are unable to replicate outside their hosts, and thus the transition time during which a virus leaves its host and infects the next susceptible host is critical for virus survival. Closely associated with hand, foot and mouth disease with occasional neurologic complications, enterovirus 71 (EV71) is stable in aqueous environments. However, its survival in the environment and interactions with bacteria are not well-established. On the other hand, Helicobacter pylori is a well-known and highly successful gut bacterial pathogen that infects 50% of individuals, with its capacity to form biofilms being linked with its transmission. We hypothesized that bacterial biofilm may play a significant role in the survival of EV71 in the external environment. In this study, we examined the interactions of EV71 with the biofilm of H. pylori. The results reveal that EV71 associated with H. pylori biofilm as observed under confocal and scanning electron microscopy. Furthermore, the presence of biofilm prolonged viral viability as demonstrated by virus plaque assays. Interestingly, the viability of the virus was dependent on the quantity of H. pylori biofilm formation. Taken together, the ability of bacterial biofilm in extending EV71 viability for prolonged periods may partially contribute to EV71 outbreaks, and implies that the association of the virus with bacterial biofilm may serve as a potential pathway of EV71 transmission.

Abstract:

Malaria and Pneumonia are leading causes of serious illness in children and adults worldwide with their death rate and prevalence on the rise. Such alarming statistics may retard the milestones so far achieved in meeting the Millennium Development Goals 4 and 6 whose targets are to improve child survival and reverse the high prevalence of diseases such as pneumonia and malaria respectively. Two sub-models of malaria-pneumonia co-infection namely malaria model and pneumonia model were considered first and then followed by the full malaria-pneumonia co-infection model. The malaria model, pneumonia model and co-infection model basic reproduction numbers denoted by Rm,Rand Rmrespectively was obtained using the Next Generation Matrix method. The model disease free equilibrium’s local and global stability was analysed using Descartes’ Rule of signs and Comparison method. The bifurcation analysis for the malaria, pneumonia and co-infection models was studied using the Centre Manifold Theory. The sensitivity indices of the model basic reproduction numbers Rm,Rand Rmp  to the parameters in the models were calculated. Optimal control theory was applied using the Pontryagins’ Maximum Principle to investigate optimal strategies for controlling the spread of malaria, pneumonia and co-infection models using insecticide treated bed nets (u1(t)), spraying of mosquitoes insecticides (u2(t)), sanitation (u3(t)), vaccination (u4(t)), anti-malaria drugs (u5(t)), anti-pneumonia drugs (u6(t)), both anti-malaria drugs and anti-pneumonia drugs (u7(t)) as the system time control variables.  Numerical simulations using a set of parameter values were provided to validate the analytical results.

Abstract:

Risk Factors of Multi-Drug Resistant Tuberculosis Among Pediatric Patients: A Retrospective Cohort Study: Determines the risk factors of pediatric patients diagnosed with MDR-TB. Conducted in a tertiary hospital in Quezon City and Health Centers from January 2011 to December 2016. A minimum cohort of 156 patients 0 – 18 years old, either bacteriologically – confirmed or clinically diagnosed tuberculosis were included in the study. Patients whose significant data of their charts went missing were excluded in the analysis. The following information were gathered a.) demographic profile: age, gender, nutritional status, socioeconomic status, district b.) clinical profile, history of exposure, results of laboratories, clinical presentation, delay in treatment, previous treatment with tuberculosis and outcome. 162 patients were analyzed, 12/162 had MDR – TB and 150/162 had Non MDR – TB. Results of univariate analysis showed that age and symptoms of weight loss, back pain, night sweats and fever had significant association with MDR TB. Of these factors, back pain (p=0.001; RR: 31.771; 95% CI: 3.801, 265.554) and fever (p=0.020; RR: 7.6587; 95% CI: 1.380, 42.494) were independent factors significantly related with MDR TB. Age, weight loss, back pain, night sweats and fever had significant association with MDR - TB. Larger sample population and a prospective study is recommended to assess the epidemiologic data and further identify other possible risk factors for resistance.

Abstract:

Excessive host inflammatory responses negatively impact disease outcomes of pneumonia. To better understand host-pathogen interactions during the critical inflammatory and repair phases of pneumonia, we investigated the role of neutrophils, neutrophil extracellular traps (NETs) and c-angiopoietin-like 4 (cANGPTL4) in the pathogenesis of influenza and pneumococcal pneumonia. The presence of NETs and the effects of cANGPTL4 were studied in mouse models of primary infection with influenza virus H1N1 and/or H3N2, and secondary pneumococcal pneumonia. Excessive infiltration of neutrophils and
significant formation of NETs were associated with severe influenza and pneumococcal pneumonia. Intense pulmonary NETs generation, elevated myeloperoxidase activity, cytokine dysregulation, pneumococcal capsule thickness determined the disease severity. Influenza infection stimulated the expression of cANGPTL4 via a direct mechanism mediated by interleukin-6 and STAT3. cANGPTL4 enhanced pulmonary tissue leakiness and exacerbated inflammation-induced lung injury. Treatment of infected mice with neutralizing anti-cANGPTL4 antibody significantly accelerated lung recovery and enhanced lung tissue integrity. The cANGPTL4-deficient mice also displayed diminished lung damage and recovered more rapidly from influenza pneumonia compared to their wild-type counterparts. Retrospective examination of lung biopsies and clinical samples from patients with infection-induced pneumonia with tissue damage revealed elevated expression of cANGPTL4 compared to normal or uninfected samples. These observations highlight the important roles that NETs and cANGPTL4 play in pulmonary infection and damage, and may facilitate the development of novel biomarkers and intervention strategies to improve the management of pneumonia. From the infection control perspective, the research also emphasizes the clinical importance of improving the coverage of influenza and pneumococcal vaccination especially among high-risk individuals.

Title: Antimicrobial Stewardship program: Is it possible in a low resource setting?
Biography:

Upasana Acharya has completed her doctor of pharmacy (post baccalaureate) and B.sc. Pharmacy  from Kathmandu university, Nepal. She is the co-coordinator for antimicrobial stewardship program at Grande International Hospital for last two years. She is also involved in critical areas for optimizing the patient medication. Her emerging interest in research works has helped to publish one of her work and few are in pipelines.

 

Abstract:

Antimicrobial Stewardship Program (ASP) aims at optimizing antimicrobial selection, dosing, route, and duration of therapy to maximize clinical cure or prevention of infection while limiting the unintended consequences, such as the emergence of resistance, adverse drug events, and cost. While ASP is embraced by most hospitals in developed world that is not the case in most low resource countries. Grande International Hospital, a multi-specialty tertiary care center, is the only hospital in Nepal where this system is being implemented since last three years. Mobilizing the needed support from the hospital leadership, Clinicians, Pharmacists, Laboratory Personnel and Nursing staff, a system of taking an approval from the ASP Committee before using certain antimicrobials is in place. A comparative retrospective observational study was conducted to evaluate the impact of ASP throughout the hospital for restricted antimicrobials. The pattern of Antimicrobial usage data six months before (October 2013 to March, 2014) and after the commencement of ASP program (April to September 2014) was analyzed.The results showed that despite the increase in inpatient admission, the consumption of higher antibiotics was reduced. For example, following the commencement of ASP, the use of Vancomycin and Colistin was reduced by about 50 % and use of Amikacin and Gentamycin was reduced by about 30%. Beta lactamase inhibitor combination use also decreased by 7%. Antimicrobial stewardship program, if implemented effectively, helps control the inappropriate use of antibiotics in the hospital setting and thereby reducing the risk of emergence of drug resistant organisms, adverse drug effects and cost.

Gbenga J. Abiodun, PhD is a young scientist whose research interest focuses on biomathematics, epidemiology and mathematical modelling of the impacts of climate (variability and change) on vector-borne and infectious diseases. He completed his Masters and Doctoral degrees in Mathematics at the University of the Western Cape (UWC) in 2012 and 2016, respectively. Dr. Abiodun has worked extensively on infectious diseases and published peer-reviewed papers in highprofile international journals.

Abstract:

The reasons for malaria resurgence mostly in Africa are yet to be well understood. Although the causes are often linked to regional climate change, it is important to understand the impact of climate variability on the dynamics of the disease. However, this is difficult due to the unavailability of long-term malaria data over the study areas. In this study, we develop a climate based mosquito-human malaria model to study malaria dynamics in the human population over KwaZulu-Natal, one of the epidemic provinces in South Africa, from 1970-2005. We compare the model output with available observed monthly malaria cases over the province from September 1999 to December 2003. We further use the model outputs to explore the relationship between the climate variables (rainfall and temperature) and malaria incidence over the province using principal component analysis, wavelet power spectrum and wavelet coherence analysis. The model produces a reasonable fit with the observed data and in particular, it captures all the spikes in malaria prevalence. Our results highlight the importance of climate factors on malaria transmission and show the seasonality of malaria epidemics over the province. Results from the principal component analyses further suggest that, there are two principal factors associated with climates variables and the model outputs. One of the factors indicate high loadings on Susceptible, Exposed and Infected human, while the other is more correlated with Susceptible and Recovered humans. However, both factors reveal the inverse correlation between Susceptible- Infected and Susceptible-Recovered humans respectively. Through the spectrum analysis, we notice a strong annual cycle of malaria incidence over the province and ascertain a dominant of one year periodicity. Consequently, our findings indicate that an average of 0 to 120-day lag is generally noted over the study period, but the 120-day lag is more associated with temperature than rainfall. This is consistence with other results obtained from our analyses that malaria transmission is more tightly coupled with temperature than with rainfall in KwaZulu-Natal province.

Abstract:

Cyclosporiasis is an emerging worldwide infection caused by an obligate intracellular protozoan parasite, Cyclospora caytenensis. The standard treatment for cyclosporiasis is a combination of two antibiotics, trimethoprim and sulfamethoxazole. Many side effects were reported with this combination with no alternative drug treatment option. In this study, silver nanoparticles were chemically synthesized to be evaluated for the first time for their anti-cyclospora effects in both immunocompetent and immunosuppressed experimental mice in comparison to the standard treatment. The effect of silver nanoparticles was assessed through studying stool oocysts’ load, oocysts’ viability, ultrastructural oocysts’ changes, and estimation of serum gamma interferon. Toxic effect of the drug was evaluated by measuring liver enzymes, urea and creatinine in mice sera. Results showed that silver nanoparticles had promising anti-cyclospora potentials. The animals that received these nanoparticles showed statistically significant decrease in the oocysts’ burden and number of viable oocysts in the mice stool and a statistically significant increase in serum gamma interferon in comparison to the corresponding group receiving the standard treatment and to the infected non-treated control group. Scanning Electron microscopic examination revealed mutilated oocysts with irregularities, poring and perforations. These effects were more pronounced in immunosuppressed animals. Biochemical results showed no evidence of toxicity as mice sera showed a statistically significant decrease in liver enzymes, and statistically non-significant decrease in urea and creatinine. Thus, silver nanoparticles proved their effectiveness against Cyclospora infection and this will open the way to its use as an alternative to the standard therapy.

Abstract:

Background: Multidrug-Resistant Organisms (MRO) including Vancomycin-Resistant Enterococci (VRE), Staphylococcus aureus and the new yeast Candida auris (MDRCA) are often passed from person to person by the contaminated hands of caregivers.

Hands become contaminated by contact with patients infected with MRO or contaminated surfaces. Cleaning hands with soap and water or use alcohol-based hand rubs (ABHR) are the main recommendation of WHO for preventing the spread of MRO in health care settings.  However, the efficacy of ABHR against MRO is not well documented Objectives: Determine the efficacy of different formulations of ABHRs (gel and foam) against different strains of MDRO such as VRE, MRSA, Klebsiella and the recent discovered multidrug-resistant yeast Candida auris.

Methods: Three ABHR ranging from 62% to 70% alcohol content in gel and foam format were evaluated using a 15 second in vitro Time-Kill (ASTM E 2315)  against several strains of S. aureus. In addition, two formulations of ABHR (gel and foam 70%) were tested against more than 40 strains of antibiotic susceptible and resistant bacteria. For C. auris a different formulation of ABHR was also included. Statistical comparison of log10 reductions (LR) was performed using the Fisher’s LSD Test (p<0.05).

Results: ABHR formulations gel or foam from 62-70% ethanol content, reduced all strains of bacteria antibiotic sensitive or resistant as well as C. auris tested by ≥ 6 log10 (≥ 99.9999%) in 15 seconds.

Conclusions: No differences in susceptibility to alcohol were shown by antibiotic resistant bacteria when compared to the sensitive strains. Alcohol 60% or higher showed the same level of efficacy. The emerging multidrug-resistant yeast Candida auris also showed complete susceptibility to the 3 formulations tested. These results support WHO recommendations for use of ABHR by healthcare personnel for preventing the spread of MRO

Abstract:

Healthcare workers are in close contact with high-risk inpatients and have the potential to transmit and disseminate healthcare-associated infections. Significant costs, advanced medical care, more extended hospital stay, usage of expensive and stronger antibiotics leading to antibiotic resistance are the adverse consequences of HAIs.The goal of the current study was to understand the perspectives of the healthcare workers on the current protocol and guidelines for HAI and infections control measures in the hospital, the effectiveness of the current protocol for HAI and infection control measures and ways of reducing the incidence of HAI and improve infection control measures.

Methodology: A qualitative research design was used to collect the data from 25 healthcare workers consisting of doctors and nurses, recruited by Snowball strategy via semi-structured interviews which were audio-recorded and transcribed verbatim immediately. An interview guide comprising of open-ended questions about the existing HAI and infection control practices was used to collect the data. Data were analyzed using the thematic analysis method.

Results Using thematic analysis four themes were identified.1.Knowledge of HAI and infection control 2. Infection control measures in practice 3. The gap in infection control measures and HAI 4. Required Implementations.

Conclusion: The study concluded that there is a need for better educational programs and hands-on training for all the healthcare personnel including the paramedical staff as well. The residents should have adequate knowledge of infection control practices to guide the nurses and should share the responsibility with the nurses in the practice of active infection control measures

Title: Effect of Nurse Leaders’ Observations on Staff Hand Hygiene Adherence
Biography:

Elizabeth completed her Bachelor of Science in nursing degree in 2007. She is currently completing her Master of Science in nursing with a leadership concentration, scheduled to graduate this May 2018. She has been working full time as nurse in many different departments, such as outpatient surgery, spinal cord injury rehabilitation, and intensive care. She is currently the infection control officer for a single specialty ambulatory surgery center.

 

Abstract:

Surgical site infections (SSIs) and other healthcare acquired infections (HAIs) continuously contribute to longer lengths of stay, unnecessary deaths, and increased costs for healthcare organizations. This is an ongoing concern that is attributed to one simple task, hand hygiene. Poor hand hygiene adherence rates are common among healthcare workers. Utilizing nursing leadership and frequent monitoring was conducted in this study to assess the influence leadership has on staff hand hygiene adherence rates. A total of eight participants received education and compliance data from the previous year prior to the study and weekly reminders during the study. The nurse leader observed a total of 139 hand hygiene opportunities, monitoring this task weekly versus quarterly, and reported a 40% increase in adherence rates from the previous year. These results indicate that leadership has a significant influence on staff, along with an increased frequency of direct monitoring. Results of SSIs during the study were not available, but it was expected that a decrease in those rates would occur with an improvement in hand hygiene.

Abstract:

In today's world, due to the importance of occupational health and the prevention of such outbreaks, this group of diseases has been considered by the centers of decision making, and health care.

In some occupations, owing to the conditions of work, the type of activity, as well as the production or consumption of different substances, people are exposed to harmful biological agents and become infected with the disease. Among work-related infectious diseases, there is a group of infectious diseases caused by various occupational travels which is of particular importance to the general public since there are a lot of jobs which need travel. Special attention to the prevention and treatment of these diseases can reduce the risks and threats in various societies in this regard.

To achieve this significant goal, the identification of work-related infections attributed to travelling, the identification of biological agents, the conditions for the development of diseases, and the ways of prevention, transfer and new treatments are discussed in this study.

Abstract:

Malaria, a preventable mosquito-borne disease, constitutes a major public health problem globally, particularly in Africa where it kills an estimated 394,680 people annually. In Ghana, Malaria accounts for 38.9% of all outpatient illnesses and 38.8% of admissions. Malaria is a priority disease under surveillance. The objective of the study was to evaluate the effectiveness
of the surveillance system and assess the attributes and make appropriate recommendations. We interviewed stakeholders and key informants using semi-structured questionnaires to understand the system operations. We reviewed and compared 2012-2016 malaria registers and reporting forms with existing data in the DHIMS 2. Using SPSS version 21, descriptive data analysis was done. CDC updated guidelines for evaluating public health surveillance system was used in assessing the attributes. Positive malaria cases declined from 50,504 in 2012 to 43,467 in 2013, continual increased to 56540 (47.1%) in 2016. Under 5 positive cases recorded, 2012 recorded 17,852 (35%), 2015 and 2016 recorded17,611(32.8%) and 18,475(32%) respectively. Age group, 1-4 have the highest positive malaria cases, with mean 5,919. Of 88,103 malaria cases treated in 2014, 38.1% (n=33532) were not tested, 13% (n=8739) of 67,295 cases treated were not tested in 2016. Reporting rate of malaria datasets was 97.5%, three (3) out of (30) facilities do not report cases. The system is flexible, sensitive and stable. Timeliness (86%), Completeness (20) and predictive positive value 53,567 (49%) were poor in 2015. The surveillance system is meeting its objectives. Improvement on data completeness and timeliness needs to be done. Suspected malaria should be tested before treatment and followed up. Rigorous supervision on proper documentation and timely reporting should be enforced in the Municipality.

Emily Acheson is currently a PhD candidate in Geography at the University of British Columbia in Vancouver, Canada in spatio-temporal modelling of Cryptococcus gattii, a medically-relevant fungus. For her Master’s at the University of Ottawa, she studied the geographical distributions of mosquitoes and tsetse flies transmitting malaria and sleeping sickness, respectively. Her research uses GIS methods to approach disease vector or pathogen distributions from a macroecological perspective. 

 

Abstract:

Why do infectious diseases emerge where they do? Climatic and land use changes are considered the two major factors, with increasing debate around which factor is more important. In Canada, a fungus called Cryptococcus gattii emerged on Vancouver Island in 1999 for unknown reasons, capable of causing a potentially fatal respiratory and neurological disease upon inhalation of its spores. The research project proposed here aims to investigate the environmental factors behind the emergence of C. gattii on Vancouver Island using geographic information systems and remote sensing. Environmental data (e.g. seasonal temperature, precipitation, etc.) at 30-m resolution for Vancouver Island were collected from the ClimateBC program for 1984-2012. Annual land cover and forest harvest data, as well as elevation, were also used. Georeferenced C. gattii occurrence records provided by the British Columbia Centre for Disease Control were used to determine the corresponding environmental data at their time of collection and in the years prior to isolation. This oral presentation will show the results of these analyses, focusing on common environmental traits of areas where C. gattii was isolated from the environment. How did these areas (i.e. grid cells) change in the 10-15 years prior to C. gattii’s isolation in that area?

Abstract:

Introduction: The emergence of multidrug- resistant (MDR) in gram negative pathogens such as P. aeruginosa has become an important challenge to worldwide public health, recently. Colistin as a last line of treatment against MDR gram negative bacteria has been propounded. Recent studies have been demonstrated that colistin resistance is adaptive and regulated via PmrA and PmrB as a two component regulatory system (3). The plasmid borne colistin resistance gene mcr-1 was primarily recognized from China (4). Due to the raising of antibiotic resistance, in this study prevalence of mcr-1 gene and the mutation in pmrA and pmrB genes in P. aeruginosa isolates from sputum of Cystic Fibrosis (CF) patients was investigated.
Methods: 41 isolates of P. aeruginosa from sputum of CF patients in Mofid Children Hospital during Apr-Sep 2017 were
collected. According to CLSI guideline 2017, antibiotic susceptibility test (AST) was applied by using the disk diffusion method Detection of pmrA, pmrB and mcr-1 genes was performed by PCR and further sequencing was administrated for finding the mutations.
Results: Among 41 isolates of P. aeruginosa 22 (53.65%) were resistant to Amikacin, 21 (51.21%) to Ofloxacin and Cefepime, 20(48.78%) to Imipenem, 19 (46.34%) to Ceftazidime and Ciprofloxacin, 18 (43.9%) to Aztreonam, 17 (41.46%) to Piperacillin,16 (39.02%) to Gentamicin, 14 (34.14%) to Pipracillin-Tazobactam and 1 (2.43%) to Colistin. PCR results showed that all ofthe isolates had pmrA and pmrB genes and all of them were negative for mcr-1. One of the isolates show some mutations in pmrB gene.
Conclusion: The results of this study showed that colistin is the best choice for treatment. Using the molecular tests is necessary and have a determinative role to prescription of antibiotics by physicians.

As one of the most dangerous invasive species in the world, Pine Wood Nematode (Bursaphelenchus xylophilus) is the causal agent of pine wilt disease which causes enormous ecological and financial losses by damaging the pine forest resources in Asia, North America and Europe. It has been reported that pine wood nematode has infested to the area where climate is relatively cold, and infestation area will continue expensing to colder regions of Asian and Europe. Our hypothesis is that low temperature-induced lifespan extension is not a passive thermodynamic process but an active one which can be promoted by genetic programs at low temperature. To decipher the low temperature induced lifespan extension in pine wood nematode, my group studied the molecular mechanism of this phenomenon. The results shows that the cold induced lifespan extension is regulated by several genetic pathways including cGMP pathway. This study provided new ideas for the control of this devastating plant parasite nematode.

Abstract:

Sexually transmitted infections (STIs) remain a public health problem globally with youth disproportionately affected by the epidemic. Furthermore, high prevalence of STIs have been linked with mining communities in the literature. The combined effect of being young and resident in a mining community therefore increases the vulnerability of this population to STIs. It is against this background that the study seeks to ascertain the knowledge, attitudes, and perceptions of STIs among youth in the Obuasi mining community. Using a qualitative approach, five focus group discussions that recruited 52 participants aged 15-24 years were conducted. The main themes for the FGDs were knowledge, perceptions, and attitudes on STIs. Results from the study revealed that youth in the mining community had fair knowledge of STIs generally, however, this knowledge is limited and fraught with misconceptions such as, candidiasis is an example of STI, oral contraceptives can prevent STIs, and all STIs are viral infections. It was also found that condom use is a preferable STI prevention method for the youth, yet they do not have extensive knowledge about condom use. Moreover, stigma, shame and unavailability of testing and treatment centers at the community level are major barriers to youth sexual health improvement and STIs control generally. Since behavior change which is influenced by knowledge, attitudes and perceptions is vital to the fight against STIs among the youth, any future interventions for STIs should include or better still target increasing STI knowledge, and improving attitude of youth in mining communities.

Abstract:

Background: Tuberculosis is a chronic, systemic infectious disease caused by M. tuberculosis mostly infecting the lung to cause pulmonary tuberculosis or localize in alternate body sites leading to extra-pulmonary tuberculosis (EPTB).The P2X7 receptor expressed in a wide variety of normal and disease-associated cell types, activated by extracellular adenosine 5’-triphosphate results in numerous events including the release of pro-inflammatory mediators, cell proliferation or death, and killing of intracellular pathogens. A deficiency of P2X7-mediated control of mycobacterial infection within macrophages in the lung may permit spread to extrapulmonary sites where the infection either progresses to post–primary TB disease.
Methods: One hundred and twenty tuberculosis patients with 46 apparently healthy controls were included for genotyping of the P2X7 polymorphism using Polymerase chain reaction and restriction fragment length polymorphism (PCR –RFLP) and confirmed by sequencing a subset of samples.
Results: This study found that the P2X7 1513A/C polymorphism is significantly associated with tuberculosis infection (CC, AC OR=4.615, 2.058). The pulmonary tuberculosis was the most predominant in the study population but the CC, AC allele had statistical significant association with the Extra-pulmonary tuberculosis infections (OR=2.65). Another polymorphisms rs2230912 was detected from sequencing results may be associated with TB infections.
Conclusion: The CC genotype is associated with susceptibility to TB infections among Sudanese patients and associated with the extrapulmonary TB. Keywords: TB, P2X7, susceptibility, pulmonary TB, Extra-pulmonary,PCR, RFLP.

Abstract:

Background: Clients have explicit desires or requests for services when visiting hospitals; inadequate discovery of their needs may result in dissatisfaction.  Patient satisfaction influences retention in HIV care, adherence to HAART and serves as determinant to HIV suppression. This study’s objectives were to quantify clients’ satisfaction with HIV services in Bamenda and determine relationship between satisfaction and clients’ socio-demographic/structural characteristics.

Methods: A cross-sectional study was conducted on HIV-positive patients followed-up, on treatment and who consulted in the Bamenda Regional Hospital treatment centre between July and August 2014. Participants consent was sought and data collected on client’s level of satisfaction to staff-patient-communication, staff attitudes, privacy and confidentiality and staffing and amenities situations in the hospital. Data was collected using a structured questionnaire interviewer-administered by investigator and trained health personnel. Collected data was analyzed using Epi Info version 3.5.4 and clients’ satisfaction measured using frequencies and percentages.

Results: A total of 384 participants took part in this study and their median age was 37 years (IQR: 29-46). Two hundred and seventy-four (71.4%) participants were females. Overall satisfaction with HIV services was 91.2% and participants reported less satisfaction with overall staffing and amenities situation of the centre (3.6%). In the multivariate analysis, only being female, employed and perceiving high number of nurses working at the treatment centre remained significant predictors of overall satisfaction with HIV services.

Conclusion: A high proportion of participants expressed satisfaction with HIV services. However, some dissatisfaction is masked in this high satisfaction level. This dissatisfaction underscores need to improve staff attitudes, staff-patient-communication, employ more staff and build better patient facilities. Future studies need to focus on assessing long-term progression of satisfaction levels with services and determinants of satisfaction involving larger samples in many treatment centres.

Abstract:

Hospital-associated infections (HAIs) has an impact on patients, personnel and the hospital. This an interrupted time series design study aimed to assess the effect of using collaborative quality improvement (CQI) of infection prevention in tertiary care hospital. The samples were selected by purposive sampling from the patients, who were HAIs and admitted into 6 intensive care units (ICUs) and 36 general wards. Data were collected from May, 2017 to January, 2018. The study instruments were a surveillance form of HAI and impacts of HAI form developed by research. Data were analyzed using descriptive and multiple linear regression statistics. The results revealed that reduction in HAIs, from 35.7 % (1,219/3,417 patients) before implementing CQI to 27.6 % (994/3,608 patients) after implementing CQI at a 0.05 statistically significant levels. Indicated the highest infection rate was from ventilator-associated pneumonia (VAP) 5.6 per 1,000 ventilator-days, followed by catheter-associated urinary tract infection (CAUTI) 3.1 per 1,000 catheter-days and central line-associated bloodstream infection (CLABSI) 1.9 per 1,000 catheter-days. Case fatality rate from VAP, CLABSI and CAUTI were 38.4%, 31.7% and 17.3%. Cost of antibiotic treatment for VAP, CAUTI and CLABSI were 91,153.45 USD, 74,342.72 USD and 20,114.27 USD, respectively. These finding imply that the concept of CQI could be applied to reduce incidence and preventive of HAIs. However, it is interesting to see if the results are sustainable and hospital still proceed with their work.

Abstract:

Acute kidney injury is a frequent and potentially fatal complication in infectious diseases. The aim of this study was to investigate the clinical aspects of AKI associated with infectious diseases and the factors associated with mortality. This retrospective study was conducted in patients with AKI who were admitted to the intensive care unit (ICU) of the Clinique de l’Ogooue Port-Gentil, Gabon, from January 2013 to January 2017. The major underlying diseases and clinical and laboratory findings were evaluated. A total of 253 cases were included. The mean age was 46±16 years, and 72% of the patients were male. The main diseases were human immunodeficiency virus (HIV) infection, HIV/acquired immunodeficiency syndrome (AIDS) (30%), tuberculosis (12%), malaria (11%) and Hepatitis B (4%). The patients were classified as risk (4.4%), injury (63.6%) or failure (32%). Mortality was higher in patients with HIV/AIDS (76.6%, p-value=0.02). A multivariate analysis identified the following independent risk factors for death: oliguria, metabolic acidosis, sepsis, hypovolemia, the need for vasoactive drugs, and the need for mechanical ventilation. AKI is a common complication in infectious diseases, with high mortality. Mortality was higher in patients with HIV/AIDS, most likely due to the severity of immunosuppression and opportunistic diseases.

Abstract:

AIMS: In nigeria, Hepatitis C virus (HCV) infection is primarily spread through injection drug use. There is an urgent need to improve access to care for HCV among persons with opioid use disorders who inject drugs. The purpose of our study was to determine the prevalence of HCV, patient characteristics, and receipt of appropriate care in a sample of patients treated with buprenorphine for their opioid use disorders in a primary care setting.

Methods: This study used retrospective clinical data from the electronic medical record. The study population included patients receiving buprenorphine in the office based opioid treatment (obot) clinic within the adult primary medicine clinic at lagos medical center between october 2008 and august 2015 who received a conclusive HCV antibody ab test within a year of clinic entry. We compared characteristics by HCV serostatus using pearson's chi-square and provided numbers/percentages receiving appropriate care.

Results: The sample comprised 300 patients. Slightly less than half of all patients (n = 134, 27.7%) were HCV ab positive, and were significantly more likely to be older hausas and yoruba’s, have diagnoses of post- traumatic stress disorder (ptsd) and bipolar disorder, have prior heroin or cocaine use, and be hi v- infected. Among the 134 HCV ab positive patients, 126 (67.7%) had detectable HCV ribonucleic acid (rna) indicating chronic HCV infection; only 8 patients (2.21%) with chronic HCV infection ever initiated treatment.

Conclusion: Nearly half of patients (47.7%) receiving office-based treatment with buprenorphine for their opioid use disorder had a positive Hepatitis C Virus antibody screening test , although initiation of HCV treatment was nearly non-existent (2.21%).

Title: Bacterial Dissemination and Molecular Surveillance in public hospital in South Africa
Biography:

Christiana Omowunmi Shobo obtained her Masters degree from the university of Kwazulu Natal, South Africa where she investigated the Antibiotic resistant profiles of Campylobacter spp. in the South African private health care sector and she passed with summa cum laude. Owing  to  her  love  for  research  she  is  currently  studying  towards  her  PhD  degree  in  Medical Microbiology.  Her  researh  interest  is  using  Next  Generation  Sequecing  (NGS)  in  combacting hospital acquired infection.

 

Abstract:

In South Africa it is estimated that approximately 1 in 7 patients entering South African hospitals are at high risk of acquiring a hospital-acquired infection (HAI). Quantitative cross-sectional studies were performed in four public hospitals in the eThekwini district of KwaZulu-Natal province, South Africa  from  September  to  November,  2017.  Focus  was  on  three  wards  viz.  intensive  care  unit, paediatric  ward  and  general  male  ward.  Within  each  ward  5  sites  were  swapped  viz.  drip  stand, patient files, patient bed, sink and ward reception. DNA was extracted using PureLink Microbiome DNA purification kit followed by amplification of the V3-V4 region of the 16S amplicon. Resulting PCR product was sequenced on an Illumina® MiSeq platform.

Metagenomic data analysis revealed distinct diversity in the microbial populations associated with various hospital sites investigated. Bacteria made up more than 85% of the DNA reads compared to viruses or unclassified kingdom levels. Proteobacteria followed by Bacteroidetes and Firmicutes are the  top  phylums.  The class  mostly presented  is  Gammaproteobacteria,  Flavobacteria  and  Baccili. The    highest    frequency    of    bacteria    originated    from    the    order    Pseudomonadales    and Enterobacteriales.  The  common  families  found  was  Moraxellaceae  and  Enteriobacteriaceae.  As expected, Acinetobacter was found at genus level, but the variety of species was a surprise. Contact with contaminated surfaces in the health care setting attributes to  cross  infection. Variations was found  within  sites,  wards  and  between  hospitals.  The information  can  assist  IPC  officers  to  deal with  the  hospital  “microbiota”  and  a  guideline  to  ascertain  any  shifts  or  variation  in  bacteria composition
