Undergraduate Learning in the COVID-19 Pandemic: Lessons Learned and Ways Forward.

The SARS-CoV-2 coronavirus (COVID-19) pandemic is in constant evolution, much like the virus, and we must learn to adapt our undergraduate education and learning strategies to enable students to complete their studies. This narrative review focuses on what is currently known about the face-to-face and e-learning strategies of undergraduate medical students in resource-limited settings during the COVID-19 pandemic. The majority of studies, involving health professional students, took place in 2020. Few involved educators. Students have faced challenges with the transition to remote learning, for which a couple of interventions have been devised. Bridging the gap in access and utilisation of remote learning might have required more time, however, the COVID-19 pandemic has accelerated the learning curve and the transition from in-person to online learning.

Clinical Characteristics and Outcomes of Patients Hospitalized with COVID-19 at Case Hospital, Uganda.

Data on clinical outcomes of patients hospitalized with coronavirus disease 2019 (COVID-19) in private health facilities in Uganda is scarce. We conducted a retrospective cohort study of patients hospitalized with COVID-19 at Case Hospital, Kampala, Uganda, between June 2020 and September 2021. Data of 160 participants (median age 45 years (interquartile range [IQR]: 37-57) and 63.5% male) was analyzed. Seventy-seven (48.1%) participants had non-severe, 18 (11.3%) severe, and 83 (51.9%) critical COVID-19 illness. In 62 participants with chest computed tomography findings, 54 (87%) had bilateral disease, with 22 (35%) having ground-glass opacities. The median duration of hospitalization was 5 days (IQR: 3-9 days). Overall, 18 (11.3%) participants died. Survival at 14 and 28 days was 89% and 72%, respectively. Factors strongly associated with all-cause mortality were as follows: age >50 years (odds ratio [OR]: 8.6, 95% confidence interval [CI]: 1.1-69.2, and p=0.042), having at least 1 comorbidity (OR: 3.2, 95% CI: 1.1-8.9, and p=0.029), hypertension (OR: 3.2, 95% CI: 1.2-8.6, and p=0.024), diabetes mellitus (OR: 2.9, 95% CI: 1.0-8.5, andp=0.056), and oxygen saturation <92% (OR: 5.1, 95% CI: 1.8-14.4, and p=0.002). In this private health facility, mortality was about 1 in 10 patients, and more people presented with critical illness in the second wave of the pandemic, and most deaths occurred after 2 weeks of hospitalization.

Factors associated with prolonged hospitalization of patients with corona virus disease (COVID-19) in Uganda: a retrospective cohort study.

INTRODUCTION: Identification of factors predicting prolonged hospitalization of patients with coronavirus disease (COVID-19) guides the planning, care and flow of patients in the COVID-19 Treatment Units (CTUs). We determined the length of hospital stay and factors associated with prolonged hospitalization among patients with COVID-19 at six CTUs in Uganda. METHODS: We conducted a retrospective cohort study of patients admitted with COVID-19 between January and December 2021 in six CTUs in Uganda. We conducted generalized linear regression models of the binomial family with a log link and robust variance estimation to estimate risk ratios of selected exposure variables and prolonged hospitalization (defined as a hospital stay for 14 days or more). We also conducted negative binomial regression models with robust variance to estimate the rate ratios between selected exposures and hospitalization duration. RESULTS: Data from 968 participants were analyzed. The median length of hospitalization was 5 (range: 1-89) days. A total of 136/968 (14.1%: 95% confidence interval (CI): 11.9-16.4%) patients had prolonged hospitalization. Hospitalization in a public facility (adjusted risk ratio (ARR) = 2.49, 95% CI: 1.65-3.76), critical COVID-19 severity scores (ARR = 3.24: 95% CI: 1.01-10.42), and malaria co-infection (adjusted incident rate ratio (AIRR) = 0.67: 95% CI: 0.55-0.83) were associated with prolonged hospitalization. CONCLUSION: One out of seven COVID-19 patients had prolonged hospitalization. Healthcare providers in public health facilities should watch out for unnecessary hospitalization. We encourage screening for possible co-morbidities such as malaria among patients admitted for COVID-19.

Coronavirus disease-2019 morbidity and mortality among health care workers in Uganda.

Background: Health care workers (HCWs) are at increased risk of acquiring coronavirus disease 2019 (COVID-19). This study aimed to determine and compare the morbidity and mortality rates due to COVID-19 among the HCWs and the general population (non-HCWs). Methods: We conducted a retrospective chart review. We accessed electronic database of participants admitted at Mulago National Referral Hospital COVID-19 Treatment Unit (CTU) between March 2020 and September 2021. Participants with missing occupations were excluded. Results: Of 594 eligible participants, 6.4% (n = 38) were HCWs. Compared with non-HCWs, HCWs were much younger (48 versus 55 years, p = 0.020). The proportion of participants with severe disease (73.7% versus 77.6%, p = 0.442), who had not received COVID-19 vaccine (91.2% versus 94.7%, p = 0.423), mortality rate (44.7% versus 54.8%, p = 0.243) and the median length of hospitalization (6 versus 7 days, p = 0.913) were similar among HCWs and non-HCWs, respectively. A higher proportion of HCWs required oxygen therapy (24.3% versus 9.7%, p < 0.01). At admission, the presence of cough (p = 0.723), breathlessness (p = 0.722), fever (p = 0.19), sore throat (p = 0.133), comorbidities (p = 0.403) and headache (p = 0.162) were similar across groups. Rhinorrhoea was more common among HCWs (34.4% versus 16.6%, p = 0.017). Among HCWs, nurses had the highest morbidity (52.6%) and mortality (58.8%). Conclusion: The morbidity and mortality among HCWs in Uganda were substantial, with a low COVID-19 vaccination rate and a higher requirement for oxygen therapy despite a younger age.

Survival analysis of patients with COVID-19 admitted at six hospitals in Uganda in 2021: a cohort study.

BACKGROUND: Assessing factors associated with mortality among COVID-19 patients could guide in developing context relevant interventions to mitigate the risk. The study aimed to describe mortality and associated factors among COVID-19 patients admitted at six health facilities in Uganda. METHODS: We reviewed medical records of patients admitted with COVID-19 between January 1st 2021 and December 31st 2021 in six hospitals in Uganda. Using Stata version 17.0, Kaplan Meier and Cox regression analyses were performed to describe the time to death and estimate associations between various exposures and time to death. Finally, accelerated failure time (AFT) models with a lognormal distribution were used to estimate corresponding survival time ratios. RESULTS: Out of the 1040 study participants, 234 (22.5%: 95%CI 12.9 to 36.2%) died. The mortality rate was 30.7 deaths per 1000 person days, 95% CI (26.9 to 35.0). The median survival time was 33 days, IQR (9-82). Factors associated with time to COVID-19 death included; age ≥ 60 years [adjusted hazard ratio (aHR) = 2.4, 95% CI: [1.7, 3.4]], having malaria test at admission [aHR = 2.0, 95% CI:[1.0, 3.9]], a COVID-19 severity score of severe/critical [aHR = 6.7, 95% CI:[1.5, 29.1]] and admission to a public hospital [aHR = 0.4, 95% CI:[0.3, 0.6]]. The survival time of patients aged 60 years or more is estimated to be 63% shorter than that of patients aged less than 60 years [adjusted time ratio (aTR) 0.37, 95% CI 0.24, 0.56]. The survival time of patients admitted in public hospitals was 2.5 times that of patients admitted in private hospitals [aTR 2.5 to 95%CI 1.6, 3.9]. Finally, patients with a severe or critical COVID-19 severity score had 87% shorter survival time than those with a mild score [aTR 0.13, 95% CI 0.03, 0.56]. CONCLUSION: In-hospital mortality among COVID-19 patients was high. Factors associated with shorter survival; age ≥ 60 years, a COVID-19 severity score of severe or critical, and having malaria at admission. We therefore recommend close monitoring of COVID-19 patients that are elderly and also screening for malaria in COVID-19 admitted patients.

Aspergillus-specific IgM/IgG antibody serostatus of patients hospitalized with moderate-critical COVID-19 in Uganda.

Invasive pulmonary aspergillosis is known to complicate the coronavirus diseases-2019 (COVID-19), especially those with critical illness. We investigated the baseline anti-Aspergillus antibody serostatus of patients with moderate-critical COVID-19 hospitalized at 3 COVID-19 Treatment Units in Uganda. All 46 tested patients, mean age 30, and 11% with underlying respiratory disease had a negative serum anti-Aspergillus IgM/IgG antibody immunochromatographic test on day 3 (mean) of symptom onset (range 1-26), but follow up specimens to assess seroconversion were not available.

Lessons Learned from the Ebola Virus Disease and COVID-19 Preparedness to Respond to the Human Monkeypox Virus Outbreak in Low- and Middle-Income Countries.

Recently, the World Health Organization (WHO) declared the human monkeypox virus disease an international health emergency. In the past decades, infectious disease epidemics have significantly impacted low- and middle-income countries (LMICs), with coronavirus disease-2019 (COVID-19) being the most recent. LMICs, particularly in Africa and Asia, responded reasonably well by strengthening health systems, including infection prevention and control strategies, laboratory systems, risk communication, and training of essential healthcare workers for surge capacity in preparation for and response to COVID-19. With the possibility of other epidemics, such as the current epidemic of human Monkeypox, a consolidated global response is required. This article discusses lessons learned from previous Ebola and COVID-19 outbreaks and also provides recommendations on how these lessons can be useful to strengthen monkeypox disease outbreak preparedness and response in LMIC.

Prevalence of depression in Uganda: A systematic review and meta-analysis.

BACKGROUND: Depression is one of the most studied mental health disorders, with varying prevalence rates reported across study populations in Uganda. A systematic review and meta-analysis was carried out to determine the pooled prevalence of depression and the prevalence of depression across different study populations in the country. METHODS: Papers for the review were retrieved from PubMed, Scopus, PsycINFO, African Journal OnLine, and Google Scholar databases. All included papers were observational studies regarding depression prevalence in Uganda, published before September 2021. The Joanna Briggs Institute Checklist for Prevalence Studies was used to evaluate the risk of bias and quality of the included papers, and depression pooled prevalence was determined using a random-effects meta-analysis. RESULTS: A total of 127 studies comprising 123,859 individuals were identified. Most studies were conducted among individuals living with HIV (n = 43; 33.9%), and the most frequently used instrument for assessing depression was the Depression sub-section of the Hopkins Symptom Checklist (n = 34). The pooled prevalence of depression was 30.2% (95% confidence interval [CI]: 26.7-34.1, I2 = 99.80, p<0.001). The prevalence of depression was higher during the COVID-19 pandemic than during the pre-pandemic period (48.1% vs. 29.3%, p = 0.021). Refugees had the highest prevalence of depression (67.6%; eight studies), followed by war victims (36.0%; 12 studies), individuals living with HIV (28.2%; 43 studies), postpartum or pregnant mothers (26.9%; seven studies), university students (26.9%; four studies), children and adolescents (23.6%; 10 studies), and caregivers of patients (18.5%; six studies). LIMITATION: Significantly high levels of heterogeneity among the studies included. CONCLUSION: Almost one in three individuals in Uganda has depression, with the refugee population being disproportionately affected. Targeted models for depression screening and management across various populations across the country are recommended. TRIAL REGISTRATION: Protocol registered with PROSPERO (CRD42022310122).

SARS‐CoV‐2, HIV, and Mycobacterium tuberculosis triple co‐infection

Tuberculosis (TB)‐related death has increased for the first time in a decade due to the coronavirus disease 2019 (COVID‐19), globally. People living with HIV (PLWHIV) might be at a higher risk of developing COVID‐19‐related complications. Herein, we describe the first case of a patient surviving from SARS‐CoV‐2‐TB‐HIV triple co‐infection in Cameroon. A 36‐year‐old Cameroonian woman presented at the emergency unit of the Jamot Hospital, Yaoundé with symptoms of anorexia, productive cough, weight loss, and fever. The SARS‐CoV‐2 rapid antigen test on nasopharyngeal sample was positive. Chest X‐ray showed bilateral parenchymal and tracheal calcifications most consistent with prior pulmonary histoplasmosis, varicella, or TB. She was tested HIV positive, and the sputum sample tested positive for TB on auramine staining. TB therapy (rifampicin, isoniazid, pyrazinamide, and ethambutol) and COVID‐19 treatment were initiated, and the symptoms improved after 2 weeks of treatment. The SARS‐CoV‐2 rapid antigen and real‐time polymerase chain reaction tests were negative after 2 weeks. She was discharged home on antiretroviral therapy and TB therapy. Coinfection with both TB, HIV, and SARS‐CoV‐2 may be common in Cameroon but not reported. The similar clinical features of COVID‐19 and TB usually lead to misdiagnosis. Early diagnosis and initiation of appropriate treatment improve outcome. COVID‐19, TB, and HIV are infectious diseases of global public health concern. Triple Co‐infection with these diseases can create a diagnostic and therapeutic dilemma. We present a 36‐year‐old Cameroonian woman who survived SARS‐CoV‐2 – HIV‐TB triple co‐infection. Timely diagnosis and appropriate management of these infections may improve outcomes and prevent complications.

Higher intensive care unit consultations for COVID-19 patients living with HIV compared to those without HIV coinfection in Uganda.

Coronavirus disease-2019 (COVID-19) is the leading cause of death worldwide from a single infectious agent. Whether or not HIV infection affects clinical outcomes in patients with COVID-19 remains inconclusive. This study aimed to compare the clinical outcomes of people living with HIV (PLWH) and non-HIV-infected patients hospitalized during the second wave of the COVID-19 pandemic in Uganda. We retrospectively retrieved data on patients with COVID-19 who were admitted to the Mulago National Referral Hospital in Uganda between April 2021 and mid-July 2021. We performed propensity-score-matching of 1:5 to compare outcomes in COVID-19 patients living with and those without HIV coinfection (controls). We included 31 PLWH and 155 non-HIV controls. The baseline characteristics were similar across groups (all p values > 0.05). PLWH had close to threefold higher odds of having ICU consultation compared to controls (odds ratio [OR]: 2.9, 95% CI: 1.2-6.9, p = 0.015). There was a trend toward having a severe or critical COVID-19 illness among PLWHIH compared to controls (OR: 1.9, 95% CI: 0.8-4.7, p = 0.164). Length of hospitalization was not significantly different between PLWH and non-HIV controls (6 days vs. 7 days, p = 0.184). Seven-day survival was 63% (95% CI: 42%-78%) among PLWH and 72% (95% CI: 61%-82%) among controls while 14-day survival was 50% (95% CI: 28%-69%) among PLWH and 65% (95% CI: 55%-73%) among controls (p = 0.280). There was another trend toward having 1.7-fold higher odds of mortality among PLWH compared to controls (OR: 1.7, 95% CI: 0.8-3.8, p = 0.181). Our data suggest that PLWH may be at an increased risk of severe or critical COVID-19 illness requiring ICU consultation. Further studies with larger sample sizes are recommended.

Psychological Distress and Access to Mental Health Services Among Undergraduate Students During the COVID-19 Lockdown in Uganda.

Background: Lockdown is an important public health approach aimed at curbing the raging effect of the coronavirus disease-2019 (COVID-19). This study aimed at determining the impact of prolonged lockdown on mental health and access to mental health services among undergraduate students in Uganda. Methods: An online cross-sectional study was conducted anonymously among undergraduates across 10 universities in Uganda. The Distress Questionnaire-5 (DQ-5) and the Patient Health Questionnaire-2 (PHQ-2) were used. Logistic regression analysis was conducted to determine factors associated with psychological distress. Results: We enrolled 366 participants with a mean age of 24.5 ± 4.6 years. The prevalence of psychological distress was 40.2% (n = 147) (cut off 14/25 based on DQ-5) while depression stood at 25.7% (n = 94; cut off 3/6 based on PHQ-2) with mean scores of 12.1 ± 4.6 and 1.7 ± 1.6 respectively. Female gender (aOR: 1.6, 95%CI: 1.0-2.6, p = 0.032), pursuing a non-medical program (aOR: 2.2, 95%CI: 1.3-3.7, p = 0.005) were factors associated with psychological distress while non-medical program (aOR: 2.2, 95%CI: 1.3-3.7, p = 0.005) was associated with increased depression. Access to mental health services was associated with both reduced distress (aOR: 0.5, 95%CI: 0.3-0.8, p = 0.005) and depression (aOR: 0.6, 95%CI: 0.3-0.9, p = 0.034). A majority (65.3%) of the participants reported knowing how to access mental health care and 188 (51.4%) reported having needed emotional support but, only 67 (18.3%) ever sought care from a mental health professional. Of those who had access, only 10 (7%), and 13 (9%) accessed a counselor or a mental health unit, respectively. The barriers to accessibility of mental health care included financial limitations (49.5%), lack of awareness (32.5%), lack of mental health professionals (28.4%), and stigma (13.9%). Conclusion: Among university students in Uganda during the COVID- 19 lockdown, the burden of psychological distress and depression was substantial. However, access to mental health services was limited by several factors.

Prevalence and Factors Associated With Depression and Suicidal Ideation During the COVID-19 Pandemic Among University Students in Uganda: A Cross-Sectional Study.

Background: The COVID-19 pandemic has negatively impacted psychosocial well-being and mental health of students across the world. Although students are vulnerable to depression and suicidal ideation, few studies have been conducted in Uganda. This study aimed to determine the prevalence of depression and suicidal ideation, and associated factors among undergraduate university students in Uganda. Methods: A cross-sectional study was conducted among undergraduates [N = 540; 363 males; mean age = 23.3 (± 2.64) years] recruited from four universities using an online questionnaire that explored sociodemographic factors, depression, and other associated factors. The Patient Health Questionnaire (PHQ-9) was used to assess depression, and Item 9 was used to assess suicidal ideation in the past 2 weeks. Multivariable logistic regression analyses were performed to determine the factors associated with depression and suicidal ideation. Results: The prevalence of moderate to severe depression was 20% (n = 108) (cut-off: 10/27 based on the PHQ-9), and the prevalence of past-2-week suicidal ideation was 13.89% (n = 75) (cut-off: 1/3 based on the PHQ-9 Item 9). About half of the individuals who screened positive for depression had suicidal ideation. Factors associated with depression were: having relationship issues [adjusted odds ratio (aOR) = 1.79, 95% confidence interval (CI) = 1.13-2.81, p = 0.012], and having a history of sexual abuse (aOR = 2.06, 95% CI = 1.10-3.84, p = 0.023). Factors associated with reducing the risk of depression were: satisfaction with current academic performance (aOR = 0.50, 95% CI = 0.32-0.79, p = 0.003), and being in the fifth year of academic study (aOR = 0.16, 95% CI = 0.03-0.73, p = 0.018). Factors associated with suicidal ideation were: smoking cigarettes and/or marijuana (aOR = 4.83, 95% CI = 1.10-21.12, p = 0.037), and having financial tuition constraints (aOR = 1.85, 95% CI = 1.08-3.16, p = 0.024), However, satisfaction with current academic performance reduced the likelihood of suicidal ideation (aOR = 0.40, 95% CI = 0.23-0.70, p = 0.001). Conclusion: Approximately one-fifth of undergraduate university students were moderately to severely depressed, especially those who had relationship issues and those with a history of sexual abuse. Suicidal ideation was common among smokers and those having financial tuition constraints. Therefore, it is recommended that the university authorities implement measures to provide psychological support for the students with problems concerning financial tuition constraints, relationships, and sexual abuse. Also, all students with depression should be screened for suicidality.

Cardiovascular risk factors and clinical outcomes of patients hospitalized with COVID-19 pneumonia in Somalia.

Background: Coronavirus disease-2019 (COVID-19) is a potentially life-threatening illness with no established treatment. Cardiovascular risk factors (CRFs) exacerbate COVID-19 morbidity and mortality. Objective: To determine the prevalence of CRF and clinical outcomes of patients hospitalized with COVID-19 in a tertiary hospital in Somalia. Methods: We reviewed the medical records of patients aged 18 years or older with a real-time polymerase chain reaction (RT-PCR)-confirmed COVID-19 hospitalized at the De Martino Hospital in Mogadishu, Somalia, between March and July 2020. Results: We enrolled 230 participants; 159 (69.1%) males, median age was 56 (41-66) years. In-hospital mortality was 19.6% (n = 45); 77.8% in the intensive care unit (ICU) compared with 22.2%, in the general wards (p < 0.001). Age ⩾ 40 years [odds ratio (OR): 3.6, 95% confidence interval (CI): 1.2-10.6, p = 0.020], chronic heart disease (OR: 9.3, 95% CI: 2.2-38.9, p = 0.002), and diabetes mellitus (OR: 3.2, 95% CI: 1.6-6.2, p < 0.001) were associated with increased odds of mortality. Forty-three (18.7%) participants required ICU admission. Age ⩾ 40 years (OR: 7.5, 95% CI: 1.7-32.1, p = 0.007), diabetes mellitus (OR: 3.2, 95% CI: 1.6-6.3, p < 0.001), and hypertension (OR: 2.5, 95% CI: 1.2-5.2, p = 0.014) were associated with ICU admission. For every additional CRF, the odds of admission into the ICU increased threefold (OR: 2.7, 95% CI: 1.2-5.2, p < 0.001), while the odds of dying increased twofold (OR: 2.1, 95% CI: 1.3-3.2, p < 0.001). Conclusions: We report a very high prevalence of CRF among patients hospitalized with COVID-19 in Somalia. Mortality rates were unacceptably high, particularly among those with advanced age, underlying chronic heart disease, and diabetes.

Prevalence of burnout among university students in low- and middle-income countries: A systematic review and meta-analysis.

BACKGROUND: Burnout is common among university students and may adversely affect academic performance. Little is known about the true burden of this preventable malady among university students in low-and-middle-income countries (LMICs). OBJECTIVES: This study aimed to systematically estimate the prevalence of burnout among university students in LMICs. METHODS: We searched PubMed, Google Scholar, CINAHL, Web of Science, African Journals Online, and Embase from the inception of each database until February 2021. Original studies were included. No study design or language restrictions were applied. A random-effects meta-analysis was performed using STATA version 16.0. Heterogeneity and publication bias were assessed using Q-statistics and funnel plots, respectively. RESULTS: Fifty-five unique articles, including a total of 27,940 (Female: 16,215, 58.0%) university students from 24 LMICs were included. The Maslach Burnout Inventory (MBI) was used in 43 studies (78.2%). The pooled prevalence of burnout was 12.1% (95% Confidence Interval (CI) 11.9-12.3; I2 = 99.7%, Q = 21,464.1, p = < 0.001). The pooled prevalence of emotional exhaustion (feelings of energy depletion), cynicism (negativism), and reduced professional efficacy were, 27.8% (95% CI 27.4-28.3; I2 = 98.17%. p = <0.001), 32.6 (95% CI: 32.0-33.1; I2: 99.5%; p = < 0.001), and 29.9% (95% CI: 28.8-30.9; I2: 98.1%; p = < 0.001), respectively. CONCLUSION: Nearly one-third of university students in LMICs experience burnout. More studies are needed to understand the causes of burnout in this key population. There is a need to validate freely available tools for use in these countries.

High Mortality During the Second Wave of the Coronavirus Disease 2019 (COVID-19) Pandemic in Uganda: Experience From a National Referral COVID-19 Treatment Unit.

BACKGROUND: We evaluated clinical outcomes of patients hospitalized with coronavirus disease 2019 (COVID-19) in the second wave of the pandemic in a national COVID-19 treatment unit (CTU) in Uganda. METHODS: We conducted a retrospective cohort study of COVID-19 patients hospitalized at the Mulago National Referral Hospital CTU between May 1 and July 11, 2021. We performed Kaplan-Meier analysis to evaluate all-cause in-hospital mortality. RESULTS: Of the 477 participants, 247 (52%) were female, 15 (3%) had received at least 1 dose of the COVID-19 vaccine, and 223 (46%) had at least 1 comorbidity. The median age was 52 (interquartile range, 41-65) years. More than 80% of the patients presented with severe (19%, n=91) or critical (66%, n=315) COVID-19 illness. Overall, 174 (37%) patients died. Predictors of all-cause in-hospital mortality were as follows; age ≥50 years (adjusted odds ratio [aOR], 1.9; 95% confidence interval [CI], 1.2-3.2; P=.011), oxygen saturation at admission of ≥92% (aOR, 0.97; 95% CI, 0.91-0.95; P<.001), and admission pulse rate of ≥100 beats per minute (aOR, 1.01; 95% CI, 1.00-1.02; P=.042). The risk of death was 1.4-fold higher in female participants compared with their male counterparts (hazards ratio, 1.4; 95% CI, 1.0-2.0; P=.025). CONCLUSIONS: In this cohort, where the majority of the patients presented with severe or critical illness, more than one third of the patients hospitalized with COVID-19 at a national CTU died of the illness.

Performance and cost-effectiveness of a pooled testing strategy for SARS-CoV-2 using real-time polymerase chain reaction in Uganda.

Real-time polymerase chain reaction (RT-PCR) remains the gold standard for detection of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). This study tested the performance of a pooled testing strategy for RT-PCR and its cost-effectiveness. In total, 1280 leftover respiratory samples collected between 19 April and 6 May 2021 were tested in 128 pools of 10 samples each, out of which 16 pools were positive. The positivity rate of the unpooled samples was 1.9% (24/1280). After parallel testing using the individual and pooled testing strategies, positive agreement was 100% and negative agreement was 99.8%. The overall median cycle threshold (Ct) value of the unpooled samples was 29.8 (interquartile range 22.3-34.3). Pools that remained positive when compared with the results of individual samples had lower median Ct values compared with those that turned out to be negative (28.8 versus 34.8; P=0.0.035). Pooled testing reduced the cost >4-fold. Pooled testing may be a more cost-effective approach to diagnose SARS-CoV-2 in resource-limited settings without compromising diagnostic performance.

A Preliminary Report on Herbal Medicine Use Among Patients Hospitalized at Two-Large COVID-19 Treatment Centers in Uganda.

INTRODUCTION: Herbal medication use among patients with COVID-19 imposes a significant risk of drug-herbal interactions and adverse events. This study aimed to assess the prevalence and factors associated with herbal medicine use among patients hospitalized with COVID-19 attending two large COVID-19 Treatment Units (CTU) in Uganda. METHODS: A hospital-based descriptive cross-sectional study was conducted recruiting patients with COVID-19 hospitalized at the Mulago National Referral Hospital and Namboole Stadium CTUs. Chi-square or Fishers' exact test for categorical and Mann-Whitney U-test for numerical were used to determine the association between dependent and independent variables. RESULTS: The study was terminated early because of significant reduction in the number of patients hospitalized with COVID-19 and the closure of Namboole CTU. Of the anticipated 422 participants, we recruited 108 (25.6%). Of this, 58 (53.7%) were female, with a median age of 38 (range: 20-75) years. Forty-nine (45.4%) had received at least one dose of the COVID-19 vaccine. Fifty-eight (57.3%) of the participants had ever used herbal medicine and the majority had used them in the past 12 months (71.9%, n = 41) either before the diagnosis of COVID-19 (85.4%, n = 35) or after (36.6%, n = 15). Being vaccinated for COVID-19 (adjusted odds ratio (aOR): 3.1, 95% confidence interval (CI): 1.4-6.8, p = 0.005) and having attained tertiary level of education (aOR: 6.2, 95% CI: 1.7-23.1, p = 0.006), as well as the accessibility to herbalists (aOR: 31.2, 95% CI: 3.7-263.2, p = 0.002) were significantly associated with herbal medication use. The majority of participants reported some improvement after using herbal medicine (80.7%, n = 46) and their doctors or nurses asked almost half of the participants about herbal medicine use (49.5%, n = 53). CONCLUSION: The use of herbal medicines to treat or prevent COVID-19 among hospitalized patients is a widespread practice in Uganda amidst unpublished evidence of their safety and efficacy.

COVID-19, HIV-Associated Cryptococcal Meningitis, Disseminated Tuberculosis and Acute Ischaemic Stroke: A Fatal Foursome.

BACKGROUND: Several viral, bacterial and fungal co-infections have been associated with increased morbidity and mortality among patients with COVID-19. We report a fatal case of severe COVID-19 pneumonia in a patient with a recent diagnosis of advanced HIV disease complicated by cryptococcal meningitis, disseminated tuberculosis and acute ischemic stroke. CASE PRESENTATION: A 37-year-old Ugandan woman was diagnosed with HIV infection 8 days prior to her referral to our center. She was antiretroviral naïve. Her chief complaints were worsening cough, difficulty in breathing, fever and altered mental status for 3 days with a background of a 1-month history of coughing with associated drenching night sweats and weight loss. The reverse transcriptase-polymerase chain reaction for SARS-CoV-2 of her nasopharyngeal swab sample was positive. Chest radiograph demonstrated military pattern involvement of both lungs. The serum and cerebrospinal fluid cryptococcal antigen tests were positive. Urine lipoarabinomannan and sputum GeneXpert were positive for Mycobacterium tuberculosis. Computed tomography of the brain showed a large acute ischemic infarct in the territory of the right middle cerebral artery. Regardless of the initiation of treatment, that is, fluconazole 1200 mg once daily, enoxaparin 60 mg, intravenous (IV) dexamethasone 6 mg once daily, oral fluconazole 1200 mg once daily, IV piperacillin/tazobactam 4.5 g three times daily and oxygen therapy, the patient passed on within 36 hours of admission. CONCLUSION: Co-infections worsen COVID-19 outcomes.
