Knowledge, Attitudes, and Practices on COVID-19 Vaccination among General Adult Population in Malawi: A Countrywide Cross-Sectional Survey.

Vaccination is one of the essential measures in reducing transmission, morbidity, and mortality rates of a disease. However, the COVID-19 vaccination is facing hesitancy across the globe, Malawi included. A population-based cross-sectional study was conducted in Malawi to document knowledge, attitudes, and practices on COVID-19 vaccination. The study targeted the general adult population and employed a multi-stage sampling technique. The Census Enumeration Areas within the 16 selected districts served as a primary sampling unit. Among the total 3068 participants, 1947 (63.6%) were female. About 1039 (34.1%) participants had primary education, while only 169 (5.5%) had college education. A total of 2936 (95.7%) participants knew about the COVID-19 vaccine, and 2063 (68.4%) felt that the COVID-19 vaccine was effective. A total of 1180 (38.7%) got vaccinated. Knowledge of the COVID-19 vaccination was significantly associated with participants' education levels, location, occupation, marital status, household family income, and whether they were suffering from chronic illness or not. Overall, the level of knowledge and attitudes about the COVID-19 vaccination was good. This study has also established that different population groups have statistically different levels of knowledge and attitudes regarding COVID-19 vaccination. This study has also indicated a significant relationship between the rate of vaccination and several factors. Therefore, this calls for stakeholders to continue awareness and group-targeted tailored campaigns so as to increase COVID-19 vaccination.

Cervical cancer screening among female health workers: Evidence from a secondary health facility in Northern Malawi.

Cervical cancer is preventable and curable if identified early. Although health workers have a critical role in influencing beliefs and practices of the entire population, some studies have shown paradoxical efforts among female health workers themselves-a threat towards attainment of the triple-intervention strategy as propagated by the World Health Organization (WHO). The study aimed to assess knowledge, attitudes and practices of cervical cancer screening among female health workers. The study used a descriptive cross-sectional design. Data entry and analysis were carried out using IBM Statistical Package for Social Scientists (SPSS) version 20.0 (SPSS, Michigan Avenue, Chicago, IL, USA). The response rate was 65.4 % and mean age of 32 years with standard deviation=±8.397. The majority of participants were nurses n = 31 (43.3). There was poor knowledge on signs/symptoms and risk factors as only 15.7 % were aware of multiple sexual partners, 7.1 % for each early sexual encounter and uncircumcised men as risk factors. Regarding willingness, 77.1 % were willing to have the screening test. Their practices were rated poor as only 35.7 % (n = 25) had ever undergone screening within the past 6 years. There was poor knowledge, fair attitudes and poor practices of cervical cancer screening among female health workers. As part of the efforts to achieve sustainable development goal (SDG) target 3.4 and the attainment of WHO 90-70-90 target by 2030; this study recommends scaling up health education, social mobilization and Human Papillomavirus (HPV) vaccinations to support awareness, detection and treatment of cervical cancer. Acceptability of the current screening methods must be further explored.

A comparison of clinical outcomes among people living with HIV of different age groups attending queen Elizabeth central hospital outpatient ART Clinic in Malawi.

Introduction: Adherence to Antiretroviral Treatment (ART) in children and adolescents living with HIV in low-resource settings is not extensively studied in large cohort studies including both adults and pediatric patients. We compared rates of virological suppression, adherence and defaulting among children, adolescents and adults attending a family ART clinic at Queen Elizabeth Central Hospital; a tertiary hospital situated in the southern region of Malawi. Methods: The study was longitudinal and made use of routinely collected data for all 27,229 clinic attendees. Clinical information obtained at routine clinical visits entered electronically since 2008 was extracted in February 2017. This data was used to ascertain differences across the different age groups. Logistic regression and Cox regression models were fitted to compare rates of Virological Suppression (VS), adherence, and defaulting, respectively. Results: Younger and older adolescents (ages 10-14 years and 15-19 years respectively) were less likely to achieve VS compared to adults in the final model AOR 0.4 (0.2-0.9, 95% CI) and AOR 0.2 (0.1-0.4, 95% CI) respectively. Young children (ages 0-4 years), older children (ages 5-9 years) and younger adolescents were less adherent to ART compared to adults AOR 0.1 (0.1-0.2, 95% CI), AOR 0.2 (0.1-0.3, 95% CI), and AOR 0.4 (0.3-0.5, 95% CI) respectively. Young adults and younger children had an increased likelihood of defaulting compared to adults. Conclusion: Poor performance on ART of children and adolescents highlights unaddressed challenges to adherence. Ongoing research to explore these potential barriers and possible interventions needs to be carried out. The adherence assessment methods used and strategies for improving it among children and adolescents need to be revised at the clinic.

Coronavirus Disease 2019 (COVID-19) Reinfection Rates in Malawi: A Possible Tool to Guide Vaccine Prioritisation and Immunisation Policies.

As the fight against the COVID-19 pandemic continues, reports indicate that the global vaccination rate is still far below the target. Understanding the levels of reinfection may help refocus and inform policymakers on vaccination. This retrospective study in Malawi included individuals and patients who tested for COVID-19 infections via reverse transcriptase polymerase chain reaction (rt-PCR) from the data at the Public Health Institute of Malawi (PHIM). We included all data in the national line list from April 2020 to March 2022. Upon review of 47,032 records, 45,486 were included with a reported 82 (0.18) reinfection representing a rate of 0.55 (95% CI: 0.44-0.68) per 100,000 person-days of follow-up. Most reinfections occurred in the first 90 to 200 days following the initial infection, and the median time to reinfection was 175 days (IQR: 150-314), with a range of 90-563 days. The risk of reinfection was highest in the immediate 3 to 6 months following the initial infection and declined substantially after that, and age demonstrated a significant association with reinfection. Estimating the burden of SARS-CoV-2 reinfections, a specific endurance of the immunity naturally gained, and the role played by risk factors in reinfections is relevant for identifying strategies to prioritise vaccination.

Six months survival and risk factors for attrition for patients detected with cryptococcal antigenemia through screening in Malawi.

MAIN OBJECTIVE: A cohort of adult Malawian people living with HIV (PLHIV) testing positive for cryptococcal antigenemia was observed and followed to determine the outcomes and risk factors for attrition. METHODS CONCEPT: Eligible PLHIV were enrolled at 5 health facilities in Malawi, representing different levels of health care. ART naïve patients, ART defaulters returning to care, and patients with suspected or confirmed ART treatment failure with CD4 <200 cells/µL or clinical stage 3 or 4 were enrolled and received CrAg tests on whole blood specimens from August 2018 to August 2019. Hospitalized PLHIV were enrolled and tested for CrAg from January 2019 to August 2019, regardless of CD4 or clinical stage. Patients with cryptococcal antigenemia were managed per Malawian clinical guidelines and were followed up for six months. Survival and risk factors for attrition at six months were assessed. RESULTS: A total of 2146 patients were screened and 112 (5.2%) had cryptococcal antigenemia. Prevalence ranged from 3.8% (Mzuzu Central Hospital) to 25.8% (Jenda Rural Hospital). Of the 112 patients with antigenemia, 33 (29.5%) were diagnosed with concurrent CM at the time of enrollment. Six-month crude survival of all patients with antigenemia (regardless of CM status) ranged from 52.3% (assuming lost-to-follow-up (LTFU) patients died) to 64.9% (if LTFU survived). Patients who were diagnosed with concurrent CM by CSF test had poor survival (27.3-39.4%). Patients with antigenemia who were not diagnosed with concurrent CM had 71.4% (if LTFU died)- 89.8% (if LTFU survived) survival at six months. In adjusted analyses, patients with cryptococcal antigenemia detected after admission to inpatient care (aHR: 2.56, 1.07-6.15) and patients with concurrent CM at the time of positive antigenemia result (aHR: 2.48, 1.04-5.92) had significantly higher hazard of attrition at six months. CONCLUSIONS: Overall, our findings indicate a need for routine access to CrAg screening and pre-emptive fluconazole treatment as a way to detect cryptococcal antigenemia and prevent CM in outpatient and inpatient settings. Rapid access to diagnosis and treatment for cryptococcal meningitis (CM) with gold-standard antifungals is needed to improve survival of patients with advanced HIV in Malawi.

Comparative characterisation of COVID-19 patients with hypertension comorbidity in Malawi: a 1:2 matched retrospective case-control study.

Objective: The aim of this study was to characterize COVID-19 cases and explore the risk factors associated with mortality among hypertensive patients with COVID-19 across Malawi. Methods: A retrospective case-control study design was used to provide a detailed account of cases and to explore the risk factors associated with mortality among hypertensive patients with COVID-19. In total, 441 patients were included in the study in a ratio of one case to two controls (1:2), matched by age. Results: Deaths due to COVID-19 varied with hypertensive condition, with more deaths registered in hypertensive patients. Clinical signs and symptoms varied greatly between hypertensive and non-hypertensive COVID-19 patients, tending to be milder in the latter group. The risk of death due to COVID-19 among hypertensive patients increased with age, and was meaningfully associated with underlining comorbidities, such as HIV, TB, cardiovascular disease, and liver disease. Conclusion: Our study revealed predictive factors for mortality in hypertensive COVID-19 patients, which can be used by policy makers and healthcare practitioners to identify those at a higher risk, and to determine the appropriate treatment approach to achieve the best possible clinical outcomes.

Patient satisfaction with health care at a tertiary hospital in Northern Malawi: results from a triangulated cross-sectional study.

BACKGROUND: In 2016 the Malawi government embarked on several interrelated health sector reforms aimed at improving the quality of health services at all levels of care and attain Universal Health Coverage by 2030. Patient satisfaction with services is an important proxy measure of quality. We assessed patient satisfaction at a tertiary hospital in Northern Malawi to understand the current state. METHODS: We conducted exit interviews with patients aged ≥ 18 years using a 28 statement interviewer administered questionnaire. Patients were asked to express their level of agreement to each statement on a five-point Likert scale - strongly disagree to strongly agree, corresponding to scores of 1 to 5. Overall patient satisfaction was calculated by summing up the scores and dividing the sum by the number of statements. Mean score > 3 constituted satisfaction while mean score ≤ 3 constituted dissatisfaction. A χ2 test was used to assess the association between overall patient satisfaction and demographic variables, visit type and clinic consulted at alpha 0.05. Patient self-rated satisfaction was determined from a single statement that asked patients to rate their satisfaction with services on a five-point Likert scale. We also asked patients to mention aspects of hospital care that they did not like. Responses were summarized into major issues which are presented according to frequencies. RESULTS: Overall patient satisfaction was 8.4% (95% CI: 5.2 - 12.9%). Self-rated patient satisfaction was 8.9% (95% CI: 5.5 - 13.4%). There was no significant association between overall patient satisfaction and all predictor variables assessed. Patients raised six major issues that dampened their health care seeking experience, including health workers reporting late to work, doctors not listening to patients concerns and neither examining them properly nor explaining the diagnosis, shortage of medicines, diagnostics and medical equipment, unprofessional conduct of health workers, poor sanitation and cleanliness, and health worker behaviour of favouring relatives and friends over other patients. CONCLUSIONS: We found very low levels of patient satisfaction, suggesting that quality of services in the public health sector is still poor. It is, therefore, critical to accelerate and innovate the Ministry of Health's quality improvement initiatives to attain Malawi's health goals.

Meta-synthesis of family communication patterns during post-stroke vascular aphasia: Evidence to guide practice.

BACKGROUND: Previous studies have predominantly focused on the needs of persons with aphasia (PWA), after a stroke diagnosis. However, aphasia is found to cause communication challenges in persons with stroke and their family caregivers as a unit. Evidence is inconclusive about the communication patterns of both persons with aphasia and their family caregivers after a stroke. Studies have not been synthesized on facilitators and barriers of communication patterns between PWA and family caregivers after a stroke. AIMS: A meta-synthesis of qualitative evidence was conducted to explore family communication patterns after post-stroke vascular aphasia. METHODS: An electronic literature search of PubMed, CINAHL, Cochrane Library, PsyINFO, and Scopus was performed from January to March 2021. The methods of qualitative meta-synthesis were underpinned by Sandelowski and Barosso's guidelines. Data analysis was facilitated by Braun and Clarke thematic analysis, using NVivo 11 software. RESULTS: A total of twenty studies were included for meta-synthesis. Three themes with corresponding subthemes were identified: (1) changes in family communication patterns (subthemes: adapting to the changes in PWA after a stroke, striving toward communication recovery); (2) facilitators of family communication patterns (subthemes: supportive communication techniques, hope of recovery, time to re-adjust, and community engagement [recreational activities]); and (3) barriers of communication (subthemes: emotional turmoil and daunting tasks of rehabilitation). LINKING EVIDENCE TO ACTION: Although persons with aphasia and family caregivers are striving to achieve normalcy in communication, they are often challenged by communication deficits and protective family behaviors. Therefore, to establish effective communication, it is of paramount importance for nursing professionals to educate PWAs and their caregivers on facilitators and barriers of family communication patterns. Technology-based family communication facilitation and support groups for PWA and their family caregivers are recommended to promote family communication. The review was registered with PROSPERO (CRD42021235519).

Histopathological profile of orbito-ocular cancers at a tertiary hospital in Northern Malawi: a retrospective cross-sectional study.

Objective: Orbito-ocular cancers are a common cause of morbidity and mortality in our population, yet these cancers have not been adequately described in Malawi. This study sought to describe the burden and histopathological profile of orbito-ocular cancers in Northern Malawi. Methods and Analysis: A retrospective review of pathology reports was done. Descriptive analyses were performed to summarise patients' demographic and clinical characteristics, and histopathological results. A binary logistic regression was used to explore the association between demographic variables, site of lesion and cancer. Results: 210 pathology reports of orbito-ocular biopsies were reviewed. 60.0% of patients were female. The majority (39.5%) of patients were in the 31 to 40 age group but overall mean age (±SD) was 34.81±15.9 years. Cancer was diagnosed in 84 (40.0%) patients. Squamous cell carcinoma constituted the majority (82.1%) of cancers followed by retinoblastoma at 7.1%. Orbito-ocular cancers were associated with HIV infection (OR5.9, 95% CI 2.0 to 17.2) and intraocular tumours were 8.3 times (OR 8.3, 95% CI 2.0 to 33.8) more likely to be malignant. However, squamous cell carcinoma was the only type of cancer found in patients with HIV infection and mostly affected the conjunctiva, constituting 94.4% of cancers affecting this site. Retinoblastoma on the other hand only affected children less than 10 years of age. Conclusion: Cancer constituted a substantial proportion of orbito-ocular lesions in our study population, with conjunctiva being the common site. This calls for improved capacity to prevent, diagnose and manage orbito-oracular cancers in Northern Malawi and similar settings.

Histopathological profile of cervical biopsies in northern Malawi: a retrospective cross-sectional study.

OBJECTIVES: According to the WHO (2014), cervical cancer is the second most common cancer in women globally. More than 85% of the global cervical cancer morbidity and mortality occur in low-income and middle-income countries and the highest risk region is in Eastern and Southern Africa. Malawi has the highest age-standardised rate of cervical cancer in the world. This study was carried out to determine the histopathological profile of cervical biopsies in a public tertiary hospital in Mzuzu, northern region of Malawi. SETTING: A public tertiary hospital in Mzuzu, northern region of Malawi. PARTICIPANTS: This was a retrospective study of all cervical biopsy specimen reports received in a public tertiary hospital in northern Malawi over a period of 5 years from July 2013 to June 2018. Demographic, clinical and diagnostic data were obtained from original histopathology reports. RESULTS: A total of 500 cervical biopsy reports were reviewed during the study period. The mean age of the patients was 41.99±12.5. Age ranged from 15 to 80 years. Cervicitis accounted for 46.0% (n=162) of the total non-malignant lesions seen, followed by cervical intraepithelial neoplasm, at 24.4% (n=86) and endocervical polyp, at 20.5% (n=72). Squamous cell carcinoma (SCC) accounted for 15.6% (n=78) of the total cervical biopsies studied and 85.7% of all total malignant lesions. Adenocarcinoma and undifferentiated carcinoma were 8.8% and 4.4%, respectively of the total malignant diagnosis. All patients with malignant lesions had HIV. CONCLUSION: Our study shows that cervicitis and SCC were most common among non-malignant and malignant cervical biopsies, respectively. Since the frequency of cervical cancer is high, there is a need to have well detailed national policies to be put in place to increase detection of preinvasive lesions in order to reduce the prevalence of cervical cancer.

Seroprevalence of anti-SARS-CoV-2 antibodies in Africa: A systematic review and meta-analysis.

We estimated the seroprevalence of anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in residents of African countries and explored its associated factors. We searched PubMed, EMBASE, PsycINFO, AMED, CINAHL, DOAJ and Google Scholar databases for peer reviewed articles and pre-prints that reported anti-SARS-CoV-2 antibody seroprevalence of general or specific human populations resident in Africa. The eligible studies were evaluated using Joana Briggs Institute prevalence critical appraisal tool. Twenty-three studies involving 27,735 individuals were included in our paper. The pooled seroprevalence of anti-SARS-CoV-2 antibodies in Africa was 22% (95%CI: 14-31) with very high heterogeneity (I2  = 100%, p < 0.001). Seroprevalence was highest in studies conducted in Central Africa compared to Southern Africa, West Africa, North Africa and East Africa respectively. The number of days between the first reported coronavirus disease 2019 case in each country and when a seroprevalence study was conducted was a significant moderator of seroprevalence. Seropositivity was numerically influenced by gender and age of the participants with males and those aged below 50 years being most affected with SARS-CoV-2 infection. The highest pooled seroprevalence in Africa reported in this review should be interpreted cautiously due to high heterogeneity between studies. Continued seroprevalence surveillance is warranted to establish Africa's transition towards herd immunity.

A Systematic Review of Clinical Prediction Rules to Predict Hospitalisation in Children with Lower Respiratory Infection in Primary Care and their Validation in a New Cohort.

Background: Our goal was to identify existing clinical prediction rules for predicting hospitalisation due to lower respiratory tract infection (LRTI) in children in primary care, guiding antibiotic therapy. A validation of these rules was then performed in a novel cohort of children presenting to primary care in Malawi with World Health Organisation clinically defined pneumonia. Methods: MEDLINE & EMBASE databases were searched for studies on the development, validation and clinical impact of clinical prediction models for hospitalisation in children with lower respiratory tract infection between January 1st1946-June 30th 2021. Two reviewers screened all abstracts and titles independently. The study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews & Meta-Analyses guidelines. The BIOTOPE cohort (BIOmarkers TO diagnose PnEumonia) recruited children aged 2-59 months with WHO-defined pneumonia from two primary care facilities in Mzuzu, Malawi. Validation of identified rules was undertaken in this cohort. Findings: 1023 abstracts were identified. Following the removal of duplicates, a review of 989 abstracts was conducted leading to the identification of one eligible model. The CHARMS checklist for prediction modelling studies was utilized for evaluation. The area under the curve (AUC) of the STARWAVe rule for hospitalisation in BIOTOPE was found to be 0.80 (95% C.I of 0.75-0.85). The AUC of STARWAVe for a confirmed diagnosis of bacterial pneumonia was 0.39 (95% C.I 0.25-0.54). Interpretation: This review highlights the lack of clinical prediction rules in this area. The STARWAVe rule identified was useful in predicting hospitalisation from bacterial infection as defined. However, in the absence of a gold standard indicator for bacterial LRTI, this is a reasonable surrogate and could lead to reductions in antibiotic prescription rates, should clinical impact studies prove its utility. Further work to determine the clinical impact of STARWAVe and to identify diagnostic tests for bacterial LRTI in primary care is required.

Paediatric sickle cell disease at a tertiary hospital in Malawi: a retrospective cross-sectional study.

Introduction: Sickle cell disease (SCD) remains a major cause of childhood mortality and morbidity in Malawi. However, literature to comprehensively describe the disease in the paediatric population is lacking. Methods: A retrospective review of clinical files of children with SCD was conducted. Descriptive statistics were performed to summarise the data. χ2 or Fisher's exact test was used to look for significant associations between predictor variables and outcome variables (case fatality and length of hospital stay). Predictor variables that were significantly associated with outcome variables (p≤0.05) in a χ2 or Fisher's exact test were carried forward for analysis in a binary logistic regression. A multivariable binary logistic regression was used to identify covariates that independently predicted length of hospital stay. Results: There were 16 333 paediatric hospitalisations during the study period. Of these, 512 were patients with SCD representing 3.1% (95% CI: 2.9%- 3.4%). Sixty-eight of the 512 children (13.3%; 95% CI: 10.5% - 16.5%) were newly diagnosed cases. Of these, only 13.2% (95% CI: 6.2% - 23.6%) were diagnosed in infancy. Anaemia (94.1%), sepsis (79.5%) and painful crisis (54.3%) were the most recorded clinical features. The mean values of haematological parameters were as follows: haemoglobin (g/dL) 6.4 (SD=1.9), platelets (×109/L) 358.8 (SD=200.9) while median value for white cell count (×109/L) was 23.5 (IQR: 18.0-31.2). Case fatality was 1.4% (95% CI: 0.6% - 2.8%)and 15.2% (95% CI: 12.2% -18.6%) of the children had a prolonged hospital stay (>5 days). Patients with painful crisis were 1.7 (95% CI: 1.02 - 2.86) times more likely to have prolonged hospital stay than those without the complication. Conclusion: Anaemia, sepsis and painful crisis were the most common clinical features paediatric patients with SCD presented with. Patients with painful crisis were more likely to have prolonged hospital stay. Delayed diagnosis of SCD is a problem that needs immediate attention in this setting. Although somewhat encouraging, the relatively low in-hospital mortality among SCD children may under-report the true mortality from the disease considering community deaths and deaths occurring before SCD diagnosis is made.

Aetiology and severity of childhood pneumonia in primary care in Malawi: a cohort study.

OBJECTIVE: To determine the aetiology of community acquired pneumonia in children presenting to primary care in Northern Malawi, and to ascertain predictors for identification of children requiring hospitalisation. DESIGN: The BIOmarkers TO diagnose PnEumonia study was a prospective cohort study conducted from March to June 2016. SETTING: Primary care in Northern Malawi. PATIENTS: 494 children aged 2 -59 months with WHO defined pneumonia. MAIN OUTCOMES AND MEASURES: Number of children with bacterial infection identified and the sensitivity/specificity of WHO markers of severity for need for hospitalisation. RESULTS: 13 (2.6%) children had a bacterium consistent with pneumonia identified. A virus consistent with pneumonia was identified in in 448 (90.7%) of children. 56 children were admitted to hospital and two children died within 30 days. 442 (89.5%) received antibiotic therapy. Eleven children (2.6%) had HIV. WHO severity markers at baseline demonstrated poor sensitivity for the need for hospitalisation with a sensitivity of 0.303 (95% CI 0.188 to 0.441) and a specificity 0.9 (95% CI 0.868 to 0.926). A prediction rule to indicate the need for hospitalisation was developed. CONCLUSIONS AND RELEVANCE: The low rate of bacterial infection and high use of antibiotics in the setting of high immunisation rates highlights the changing profile of childhood pneumonia. Similarly, the markers of need for hospitalisation may have changed in the setting of extended immunisation. Further studies are required to examine this.

Histopathological profile of breast cancer at a tertiary hospital in Malawi: A retrospective cross-sectional study.

Breast cancer is one of the major public health problem in developing countries. In Malawi, cancer of the breast among females is among the top four accounting for 4.9%. The study determined the histopathologic profile of breast cancer in Northern Malawi from July 2013 to June 2018. A record based retrospective cross-sectional study was conducted at Mzuzu Central Hospital. We reviewed 202 histopathological results of breast specimens during the study period. Data was analyzed using STATA version 14.0. Out of 202 clinically diagnosed breast lesions/tumours, 102 (50.5%) were histopathologically confirmed cancerous in nature, and 100 (49.5%) were non-cancerous. Ductal carcinoma was the leading histologic presentation with 68 cases representing 66.7%. Participants in the age group of 70-89 years were 13 times more likely to develop breast cancer (OR 12.66; P-value = 0.001; 95% CI 2.79 - 57.46), compared to those in the age group 10-29 years. The magnitude of breast cancer in Mzuzu Central Hospital, Northern Malawi is alarming (50.5%). Policy makers should emphasise on awareness campaigns for early and routine breast screening, early diagnosis and early treatment.

Prevalence, distribution and antimicrobial susceptibility pattern of bacterial isolates from a tertiary Hospital in Malawi.

BACKGROUND: Bacterial infections are a significant cause of sickness and death in sub-Saharan Africa. This study aimed at establishing the prevalence, distribution and antimicrobial susceptibility pattern of major bacterial isolates from patients accessing medical care at a tertiary hospital in Malawi. METHODS: We retrospectively reviewed bacteria culture and antimicrobial susceptibility records for 4617 patients from 2002 to 2014 at Mzuzu Central Hospital (MCH). No inclusion and exclusion criteria were followed. Data was analysed using excel (Microsoft office, USA) and GraphPad prism 7 software programs. RESULTS: The most prevalent isolates were S. aureus (34.7%, n = 783), Klebsiella species (17.4%, n = 393) and Proteus species (11.4%, n = 256). Most microorganisms were isolated from adults (88.3%, n = 3889) and pus was the main source (69.3%, n = 1224). S. pneumoniae was predominantly isolated from cerebrospinal fluid (60.3%, n = 44) largely collected from children (88.2%, n = 64). Overall, most bacteria exhibited high resistance to all regularly used antimicrobials excluding ciprofloxacin. CONCLUSIONS: Our report demonstrates an increase in bacterial infection burden in sites other than blood stream and subsequent increase in prevalence of antimicrobial resistance for all major isolates. Creating an epidemiological survey unit at MCH will be essential to help inform better treatment and management options for patients with bacterial infections.

A comparative evaluation of three methods for the rapid diagnosis of cryptococcal meningitis (CM) among HIV-infected patients in Northern Malawi.

Introduction: Cryptococcal meningitis (CM) is the most common systemic fungal infection in patients with HIV infection. Rapid diagnosis and timely initiation of antifungal therapy are key to reducing mortality rate associated with CM. This study aims to evaluate the ability of four different diagnostic tests (Gram stain, India ink, and two types of commercial lateral flow assay [LFA]) to identify CM-positive patients and to compare the sensitivity and specificity of these tests. Methods: This was a prospective cross-sectional study on diagnostic tests accuracy conducted in Northern Malawi. The target population was HIV-infected adult patients presenting with features of meningitis. Four types of diagnostic tests were conducted: India ink, Gram stain, and two types of commercial lateral flow assay (LFA) (Immy, Inc., OK, USA and Dynamiker Biotechnology (Tianjin) Co., Ltd), Singapore). Culture was conducted as the reference standard. Results: A total of 265 samples were collected. The rate of positive CM detection ranged from 6.4% (using India ink) to 14.3% (using LFA). India ink exhibited the lowest sensitivity of 54.8% (95% confidence interval [CI]: 36.0%-72.7%), followed by Gram stain (61.3%; 95% CI: 42.2%-78.2%). The Dynamiker LFA exhibited the highest sensitivity of 100.0% (95% CI: 90.0%-100.0%) but a lower specificity (97.0%; 93.9%-98.8%) compared to the Immy LFA (98.3%; 95% CI: 95.7%-99.5%). Conclusion: LFA diagnostic methods have the potential to double the detection rate of CM-positive patients in resource-limited countries such as Malawi. As such, LFAs should be considered to become the main diagnostic tests used for CM diagnostics in these countries. Our data indicate that LFAs may be the best method for diagnosing CM and exhibits the highest diagnostic accuracy as it has shown that it outperforms cell culture, the current gold standard.

Diabetes and complications of the heart in Sub-Saharan Africa: An urgent need for improved awareness, diagnostics and management.

Type 2 diabetes mellitus is no longer a disease of high income countries but a global health pandemic. With the continued and rapid increase in its prevalence worldwide it is forecasted that diabetes will be a leading cause of morbidity and mortality. A major concern stems from its role in development and progression of cardiovascular disease, including cardiac dysfunction and heart failure. Within low- and middle-income areas such as Sub-Saharan Africa the burden of diabetes is already significant driven by many factors, including, socioeconomic (urbanisation), nutritional (high-calorie "western-diet", obesity) and lifestyle (physical inactivity) changes. Insufficient economic and community resources, poor health care system development and chronic disease management, poor education, and a lack of preventative and diagnostic measures further aggravate the severity of the diabetes problem. This review outlines the burden of type 2 diabetes mellitus in Sub-Saharan Africa and highlights the need for improved community health care and regulations to reduce its epidemiological spread and devastating impact on health.
