RESUMO

Introduction: Telemedicine practice experiences during the COVID-19 pandemic have not been well documented in resource-constrained settings, such as Nigeria. We set out to assess knowledge, attitude, and factors associated with telemedicine practice during the COVID-19 lockdown, as well as physician experiences in Kano, Nigeria. Methods: We employed a mixed-methods approach, utilizing structured questionnaires administered to 246 physicians, followed by in-depth interviews with a purposive subsample of 20 individuals. The data were analyzed using logistic regression and the framework approach. Results: Overall, 65.0% of the respondents demonstrated moderate to good knowledge of telemedicine. Before COVID, only 47.6% (n = 117) reported practicing telemedicine, compared with 77.2% (n = 190) during the COVID lockdown (p < 0.05). Factors associated with telemedicine practice included having at least 5 years of work experience, working in pediatrics, undergoing senior residency training, receiving formal telemedicine training, possessing good knowledge of telemedicine, and having a positive attitude toward it. The odds of engaging in telemedicine practice were four times higher (adjusted odds ratio = 4.10, 95% confidence interval: 1.79-9.40) for those who practiced it before the pandemic. Challenges identified included knowledge and skill gaps, slow internet connectivity, unstable electricity, and inadequate equipment. Conclusion: To enhance telemedicine practice in resource-limited settings, it is important to focus on strengthening information and communication infrastructure, providing comprehensive clinician training, implementing careful patient selection processes, and improving practice guidelines.

RESUMO

Introduction: Access to HIV care remains challenging, especially for patients living in remote areas, despite advances in antiretroviral treatment. The acceptability of teleconsultations for routine HIV care post-COVID is not well-explored. We explored factors influencing teleconsultation acceptability among people living with HIV (PLWH) and attending a tertiary care center in Kano, Nigeria. Methods: We used a cross-sectional mixed methods study design. Structured questionnaires were administered to 415 PLWH, supplemented by in-depth interviews with a subsample (n = 20). Logistic regression models and thematic analysis were used for data analyses. Results: Of 415 respondents, 55.7% (n = 231) expressed willingness for teleconsultations. Primary motivations included convenience/efficiency (46.7%, n = 194), elimination of travel expenses (31.8%, n = 132), and remote access to specialist care (17.3%, n = 72). Reasons for reluctance included distrust of technology (61.9%, n = 260) and privacy concerns (37.1%, n = 156). Acceptance was higher among males (adjusted odds ratio (aOR)=1.58, 95% confidence interval (CI) = 1.12-3.72), participants with at least secondary education (aOR = 1.47, 95% CI = 1.27-4.97), monthly income ≥30,000 Naira (aOR = 2.16, 95% CI = 1.21-7.31), currently married (aOR = 3.26, 95% CI = 1.16-5.65), and participants without comorbidities (aOR = 2.03, 95% CI = 1.18-4.24). PLWH who self-assessed as being in good health (aOR = 3.77, 95% CI = 1.44-9.94), used the internet regularly (aOR = 3.12, 95% CI = 2.17-5.37), or were aware of telemedicine (aOR = 3.24, 95% CI = 2.45-7.68) were also more accepting of telehealth services. Themes highlighted the need to offer teleconsultation as an optional service. Conclusion: Teleconsultation acceptance among PLWH was influenced by sociodemographic, clinical, and technology-related factors. Successful integration of teleconsultation services for PLWH in similar settings necessitates targeted educational interventions and assessment of organizational readiness.

RESUMO

Limited literature exists on men's experiences with intimate partner violence (IPV) during the COVID-19 lockdown, especially in resource-constrained settings like Nigeria. We investigated the prevalence, risk factors, and lifetime experiences of IPV among men in Nigeria, during COVID-19 restrictions. Using a mixed methods design, we interviewed 420 married men with a structured questionnaire and conducted 20 in-depth interviews. Logistic regression and a framework approach were used for data analysis. Approximately 86.4% of respondents (n=363) experienced IPV at some point in their lifetime. The prevalence of IPV during the COVID-19 restrictions was 76.2% (n=320). Over a lifetime, verbal (67.4%), physical (78.1%), and sexual coercion (81.0%) were the most common forms of IPV. During the COVID-19 lockdown, the corresponding proportions were 48.6%, 69.5%, and 57.4%, respectively. Male- and female-perpetrated IPV over a lifetime (88.3% vs 87.6%) and during COVID-19 restrictions (88.3% vs 81.4%) were similar (p>0.05). Older age, non-Muslim religion, longer marital duration, partner's profession, and no formal education were associated with higher IPV risk. Home confinement, financial stress, childbirth, disrespect towards spouse's parents, emotional detachment, disputes about child discipline, and suspected infidelity contributed to IPV. Men's active involvement in family life, improved communication, and increased transparency emerged as protective factors. Our findings highlight the high rates of IPV during the pandemic, with men as both perpetrators and victims. Future epidemic preparedness plans should prioritize IPV prevention strategies that enhance partner communication, promote male involvement in family life, address the gender education gap, and provide support services.

RESUMO

BACKGROUND: Population-level health and mortality data are crucial for evidence-informed policy but scarce in Nigeria. To fill this gap, we undertook a comprehensive assessment of the burden of disease in Nigeria and compared outcomes to other west African countries. METHODS: In this systematic analysis, using data and results of the Global Burden of Diseases, Injuries, and Risk Factors Study 2019, we analysed patterns of mortality, years of life lost (YLLs), years lived with disability (YLDs), life expectancy, healthy life expectancy (HALE), and health system coverage for Nigeria and 15 other west African countries by gender in 1998 and 2019. Estimates of all-age and age-standardised disability-adjusted life-years for 369 diseases and injuries and 87 risk factors are presented for Nigeria. Health expenditure per person and gross domestic product were extracted from the World Bank repository. FINDINGS: Between 1998 and 2019, life expectancy and HALE increased in Nigeria by 18% to 64·3 years (95% uncertainty interval [UI] 62·2-66·6), mortality reduced for all age groups for both male and female individuals, and health expenditure per person increased from the 11th to third highest in west Africa by 2018 (US$18·6 in 2001 to $83·75 in 2018). Nonetheless, relative outcomes remained poor; Nigeria ranked sixth in west Africa for age-standardised mortality, seventh for HALE, tenth for YLLs, 12th for health system coverage, and 14th for YLDs in 2019. Malaria (5176·3 YLLs per 100 000 people, 95% UI 2464·0-9591·1) and neonatal disorders (4818·8 YLLs per 100 000, 3865·9-6064·2) were the leading causes of YLLs in Nigeria in 2019. Nigeria had the fourth-highest under-five mortality rate for male individuals (2491·8 deaths per 100 000, 95% UI 1986·1-3140·1) and female individuals (2117·7 deaths per 100 000, 1756·7-2569·1), but among the lowest mortality for men older than 55 years. There was evidence of a growing non-communicable disease burden facing older Nigerians. INTERPRETATION: Health outcomes remain poor in Nigeria despite higher expenditure since 2001. Better outcomes in countries with equivalent or lower health expenditure suggest health system strengthening and targeted intervention to address unsafe water sources, poor sanitation, malnutrition, and exposure to air pollution could substantially improve population health.

RESUMO

OBJECTIVES: In the face of limited fiscal and technical resources, improvised methods have been used to provide effective and sustainable ventilatory support in low-resource settings to reduce neonatal mortality associated with respiratory complications. This study assessed the use of improvised bubble continuous positive airway pressure (ibCPAP) ventilation among neonates with respiratory complications and determined its effect on neonatal outcomes in low- and middle-income countries (LMICs). CONTENT: Hospital-based studies conducted between 2010 and 2020 in LMICs were reviewed. Rayyan® software for systematic review was used for screening and article selection. We used Stata® Statacorp Texas USA software to estimate pooled prevalence, proportion estimates, weighted mean differences and 95% Confidence Interval (CI), using the random effects model. SUMMARY: A total of 193 articles were generated and 125 were reviewed. Thirteen articles with 806 neonates on ibCPAP ventilation were included. The pooled prevalence of ibCPAP use was 7.0% (95% CI: 3.0%-13.0%). There was a significant difference in mean oxygen saturation before and after ibCPAP use (-1.34% [95% CI: -1.65% to -1.02%, p<0.01). The duration of oxygen requirement among neonates on ibCPAP was 6.5 hours less than controls (0.27 days [95%CI: -0.49 to -0.05, p<0.01). OUTLOOK: IbCPAP had no effect on the respiratory rate, duration of admission, mortality and survival. IbCPAP use in LMIC hospitals is low and its use improved oxygen saturation and duration on oxygen among the neonates, but had no impact on length of stay, respiratory rate, mortality or survival.

RESUMO

OBJECTIVES: Cesarean section is the most common obstetric surgical procedure, with associated risks for adverse neonatal outcomes. The interplay of perinatal factors associated with neonatal admissions following cesarean delivery remains poorly understood in developing countries. We examined how perinatal and facility-based factors affect Neonatal Intensive Care Unit (NICU) admission after cesarean delivery in northern Nigeria. METHODS: A prospective cohort study involving 200 women undergoing cesarean section were consecutively enrolled with subsequent follow-up of their infants in the post-natal period. Data were abstracted from the medical record using an interviewer-administered questionnaire. The primary outcomes were NICU admission and intrauterine or early neonatal deaths. Binary logistic regression modelling was used to identify variables independently associated with the outcomes. RESULTS: Over the study period (six months), there were 200 cesarean sections. A total of 30 (15.0%) neonates were admitted into the NICU following the procedure. No stillbirths or early neonatal deaths were recorded. NICU admission was associated with gestational age (preterm vs. term [adjusted odds ratio, aOR: 18.9, 95% confidence interval (CI): 4.0-90.4]), birth weight (small vs. appropriate [aOR: 6.7, 95% CI 1.9-22.7] and large vs. appropriate birth weight [aOR: 20.3, 95% CI 2.9-143.7]) and the number of indications for cesarean section (≥2 vs. one [aOR: 0.2, 95% 0.1-0.8]). CONCLUSIONS: Prematurity, small and large for gestational age neonates; and indications for cesarean section were associated with increased likelihood of neonatal admission following cesarean delivery. These findings could inform ongoing quality enhancement initiatives to improve NICU admission outcomes at the study site, and other similar settings.

RESUMO

Thyroid-like follicular renal cell carcinoma is an uncommon kidney tumor with no distinct molecular alteration described to date. This cohort of eight women with mean and median ages of 45 and 46 years, respectively (range 19-65 years), had unencapsulated, well-circumscribed tumors composed of tightly packed anastomosing follicle-like cysts filled with eosinophilic colloid-like material and lined by cuboidal cells with high nuclear to cytoplasmic ratios, oval to elongated nuclei with perpendicular arrangement toward the lumens, and prominent nuclear overlapping. The stroma between these was minimal with the exception of two tumors. Calcifications and necrosis were absent. Immunohistochemically, the tumors were positive for KRT19 (7/7), PAX8 (5/5), cyclin D1 (6/6), KRT7 (5/7), and AMACR (1/5; focal, weak), and were negative for WT1, TTF1 (transcription termination factor-1), and thyroglobulin. In three of three tumors tested molecularly, EWSR1-PATZ1 fusion was identified by RNA sequencing and confirmed by RT-PCR and Sanger sequencing. Over a follow-up period of 1-7 years, no evidence of recurrence or metastasis has been detected. The EWSR1-PATZ1 fusion has been recognized as a recurrent alteration in a subset of round to spindle cell sarcomas with EWSR1-non-ETS fusions (EWSR1-PATZ1 sarcoma) and in several central nervous system tumors. The finding of an EWSR1-PATZ1 fusion in all three of the thyroid-like follicular renal cell carcinomas for which sufficient tissue was available for genomic profiling provides the first distinct molecular abnormality in thyroid-like follicular renal cell carcinomas, supporting its designation as a distinct diagnostic entity.

RESUMO

Antiretroviral therapy has turned HIV into a chronic condition, with morbidity from HIV-associated noncommunicable diseases (NCDs) becoming more common as HIV-infected individuals live longer. In Nigeria, the additional challenge of an under-capacitated health system highlights the need for skilled clinical investigators who can generate evidence to tackle the double burden of HIV and NCDs. The Vanderbilt-Nigeria Building Research Capacity in HIV and Non-communicable Diseases (V-BRCH) programme is a training platform to create a cohort of skilled Nigerian investigators with the capacity to lead independent clinical trial research focused on the intersection of HIV and NCDs. V-BRCH will solidify an atmosphere of continuous mentoring and skills acquisition for physician faculty at the Aminu Kano Teaching Hospital via short- and medium-term learning opportunities, paired mentoring arrangements, and mentored research projects. Trainees will attend an annual faculty enrichment programme in Nashville, in addition to on-site workshops in Nigeria on HIV-associated NCD epidemiology, clinical trials methodology, evidence synthesis, qualitative research methods, stakeholder engagement, knowledge translation, and grant writing. Research-oriented junior faculty will undergo focused training in clinical trials administration and regulatory oversight. Scholars will share best practices through mentoring panels, regular 'Works in Progress' meetings, and monthly career development seminars. Competitive seed grants will be provided to mentor-mentee teams to promote targeted in-country pilot studies focused on HIV-associated NCDs. For long-term training, physician scientists will be supported to undergo enhanced Master of Public Health (MPH) training at Bayero University in Nigeria and Master of Science in Clinical Investigation (MSCI) training at Vanderbilt. Short-term regional courses, staff development workshops, and MPH curriculum refinement will help to strengthen institutional capacity in HIV-associated NCD clinical trial research. V-BRCH will create a cohort of skilled Nigerian scientists who will be able to compete for independent funding and design and implement high quality research that will generate evidence to inform policy and practice and lead to improved outcomes for Nigerians impacted by HIV-associated NCDs.

RESUMO

Bacterial community diversity of bulk water and corresponding biofilms of four intensive care units' (ICUs) drinking water systems were studied and compared using 16S rRNA gene amplicons and next generation sequencing. Proteobacteria, mainly Alphaproteobacteria and Betaproteobacteria were dominant in the bulk water and biofilms. Principal component analysis showed different bacterial communities characterizing each of the bulk water and the biofilms in three of the studied ICUs. Taxonomic classification and comparison of different genera between samples highlighted the dominance of Aquabacterium (80%) and Novosphingobium (72%) in bulk water while biofilms harbored different bacteria affiliated to Pelomonas (97%) and Caulobacter (96%), Porphyrobacter (78%) and Staphylococcus (74%). Staphylococcus aureus was the only possible pathogen found with low percentage (2.32%) in three of the ICUs' biofilm and only in one of the ICU's bulk water. This study sheds light on the prevalence of unculturable bacterial flora in the biofilm ignored by the microbiological standard methods. This study was performed on tap and bulk water from ICUs; however, it indicates the need for further studies to investigate the function and activity of the microbial diversity in order to assess the real risk presented by this water microflora on patients' health.

RESUMO

Altered epididymal sperm count and morphology following leptin treatment has been reported recently. This study examined the effects of 42 days of leptin treatment on sperm count and morphology and their reversibility during a subsequent 56-day recovery period. Twelve-week-old male Sprague-Dawley rats were randomised into four leptin and four saline-treated control groups (n = 6). Intraperitoneal injections of leptin were given daily (60 µg Kg(-1) body weight) for 42 days. Controls received 0.1 ml of 0.9% saline. Leptin-treated animals and their respective age-matched controls were euthanised on either day 1, 21, 42 or 56 of recovery for collection of epididymal spermatozoa. Sperm concentration was determined using a Makler counting chamber. Spermatozoa were analysed for 8-hydroxy-2-deoxyguanosine and DNA fragmentation (Comet assay). Data were analysed using anova. Sperm concentration was significantly lower but fraction of abnormal spermatozoa, and levels of 8-hydroxy-2-deoxyguanosine were significantly higher in leptin-treated rats on day 1 of recovery. Comet assays revealed significant DNA fragmentation in leptin-treated rats. These differences were reduced by day 56 of recovery. It appears that 42 days of leptin treatment to Sprague-Dawley rats has significant adverse effects on sperm count and morphology that reverse following discontinuation of leptin treatment.

RESUMO

Adamantinoma-like Ewing sarcoma (ALES) is a newly described rare entity, which shows EWSR1::FLI1 rearrangement characteristic of Ewing sarcoma. This can be diagnostically challenging as it manifests histologically with epithelial differentiation and has diffuse keratin expression as well as p40 and p60 positivity. We hereby report a case of ALES in a 33-year-old woman with a past medical history of breast carcinoma who presented with a right-sided parotid mass. CT scan of the neck showed a heterogenous mass within the superficial lobe, measuring 17 mm in diameter for which the patient underwent superficial parotidectomy. Histopathology of the mass revealed a malignant neoplasm formed of solid nests, cords and sheets of cells with minimal cytoplasm and monomorphic nuclei with granular chromatin and indistinct nucleoli. Brisk mitotic activity and tumor necrosis were also present. The tumor showed strong and diffuse reactivity for pankeratin (clone AE1/AE3) and keratin 20, both in a dot-like pattern, raising the suspicion of metastatic Merkel cell carcinoma; however, molecular studies showed EWSR1::FLI1 rearrangement, supporting the diagnosis of ALES. In summary, it is prudent to have knowledge about this entity to avoid its misdiagnosis as other malignancies of the head and neck region which exhibit a different clinical course, prognosis and hence treatment modalities.

RESUMO

Renal cell carcinoma with fibromyomatous stroma, recognized as a provisional entity in the current 2022 World Health Organization classification of renal neoplasms, is rare. Recent evidence suggests recurrent alterations in the mTOR pathway, supporting its recognition as a distinct entity. Herein, we report 2 renal cell carcinomas with fibromyomatous stroma with MTOR mutations occurring in 62- and 72-year-old women and review the literature to support its recognition as a distinct entity, focusing on the characteristic morphology, immunohistochemical staining patterns as well as genetic alterations.

RESUMO

HIV self-testing (HIVST) holds promise for accessing hard-to-reach populations by overcoming sociocultural and structural barriers to awareness of HIV status. This phenomenological qualitative study explored the experiences and perspectives of married men in Kano, northern Nigeria, regarding HIV testing and counseling (HTC) and HIVST. Twenty married men from diverse socioeconomic backgrounds participated in in-depth interviews conducted in the local language. Thematic analysis was employed to analyze the data, yielding key themes related to prior test experiences, knowledge of self-testing, and perceived ease of use, in addition to motivation for self-testing and concerns about reliability and counseling support. The findings shed light on the impact of facility-based HIV testing experiences on the perspectives of participants. Concerns related to delays, overcrowding, discomfort, fear, and unsupportive attitudes from healthcare providers influenced their perceptions. Among persons with previous self-testing experience, initial uneasiness was overcome with repeated use, highlighting the ease of use associated with HIVST. Motivations for self-testing included privacy, convenience, personal empowerment, improved infection detection, and efficiency. Concerns were raised regarding the reliability of self-testing results compared to hospital-based testing, and the absence of counseling support during self-testing. Our findings underscore the need to address infrastructural limitations, enhance counseling support, and promote awareness and knowledge of HIVST.

RESUMO

As persons with HIV live longer as the result of antiretroviral therapy, morbidity from HIV-associated noncommunicable diseases (NCDs) is increasing. The Vanderbilt-Nigeria Building Research Capacity in HIV and Noncommunicable Diseases program is a training platform created with the goal of training a cohort of successful Nigerian investigators to become leaders in HIV-associated NCD research. We describe survey findings from two week-long workshops in Kano, Nigeria, where trainees received instruction in implementation science and grant writing. Surveys assessed participants' self-perceived knowledge and confidence in topics taught during these workshops. Thirty-seven participants (all assistant professors) attended the implementation science workshop; 30 attended the grant-writing workshop. Response rates for the implementation science workshop were 89.2% for the preworkshop survey and 91.9% for the postworkshop survey. For the grant-writing workshop, these values were 88.2% and 85.3%, respectively. Improvement in participant knowledge and confidence was observed in every domain measured for both workshops. On average, a 101.4% increase in knowledge and a 118.0% increase in confidence was observed across measured domains among participants in the implementation science workshop. For the grant-writing workshop, there was a 68.8% increase in knowledge and a 70.3% increase in confidence observed. Participants rated the workshops and instructors as effective for both workshops. These workshops improved participants' knowledge and competence in implementation science and grant writing, and provide a model for training programs that aim to provide physician scientists with the skills needed to compete for independent funding, conduct locally relevant research, and disseminate research findings.

RESUMO

Myoepithelial tumors of the soft tissue and bone occurring in patients 21 years of age and younger are rare, and their clinicopathologic features remain incompletely understood. We studied a well-characterized series of 40 such tumors. Cases were retrieved from our archives for the period 2009-2022 and re-reviewed. Available immunohistochemical and molecular genetic data was collected. Clinical information including available follow-up was obtained. The tumors occurred in 18 males and 22 females, ranging from 3 months to 21 years of age (median 11.5 years), and involved a wide variety of soft tissue (n = 36) and bone (n = 4) locations. Histologically benign myoepithelial tumors tended to occur in adolescents (median age 14.5 years; range 5-21 years), whereas myoepithelial carcinomas occurred in younger patients (median age 8.5 years; range 3 months-20 years). Microscopically, the tumors showed a complex admixture of epithelioid, plasmacytoid and spindled cells in a variably hyalinized, myxoid, chondroid or chondromyxoid background. Small subsets of histologically malignant tumors had rhabdoid or "round cell" features. Immunohistochemistry showed 35/40 (88%) cases to be positive with at least one keratin antibody. The 5 keratin-negative tumors were uniformly positive for S100 protein and/or SOX10 and expressed EMA (4 cases) and/or p63 (3 cases). EMA, SMA and GFAP were positive in 21/25 (84%), 13/21 (62%), and 8/21 (38%) tumors, respectively. SMARCB1 and SMARCA4 expression was retained in 29/31 (94%) and 22/22 (100%) of cases, respectively. FISH for EWSR1 gene rearrangement was positive in 6/18 (33%) tested cases. Two EWSR1-negative tumors were also FUS-negative. NGS identified EWSR1::POU5F1, FUS::KLF17, and BRD4::CITED1 gene fusions in 3 tested cases. Clinical follow-up (22 patients; median 23 months; range 1-119 months) showed 3 patients with local recurrences and 5 with distant metastases (lymph nodes, lung, and brain). Three patients died of disease, 3 were alive with recurrent or unresectable disease, and 16 were disease-free. Adverse clinical outcomes were seen only in patients with malignant tumors. We conclude that myoepithelial neoplasms of soft tissue and bone are over-repesented in patients ≤21 years of age, more often histologically malignant, and potentially lethal. Histologic evaluation appears to reliably predict the behavior of these rare tumors.

RESUMO

The rising burden of antimicrobial resistance and increasing infectious disease outbreaks, including the recent COVID-19 pandemic, has led to a growing demand for the development of natural products as a valuable source of leading medicinal compounds. There is a wide variety of active constituents found in plants, making them an excellent source of antimicrobial agents with therapeutic potential as alternatives or potentiators of antibiotics. The structural diversity of phytochemicals enables them to act through a variety of mechanisms, targeting multiple biochemical pathways, in contrast to traditional antimicrobials. Moreover, the bioactivity of the herbal extracts can be explained by various metabolites working in synergism, where hundreds to thousands of metabolites make up the extract. Although a vast amount of literature is available regarding the use of these herbal extracts against bacterial and viral infections, critical assessments of their quality are lacking. This review aims to explore the efficacy and antimicrobial effects of herbal extracts against clinically relevant gastrointestinal infections including pathogenic Escherichia coli, toxigenic Clostridioides difficile, Campylobacter and Salmonella species. The review will discuss research gaps and propose future approaches to the translational development of plant-derived products for drug discovery purposes for the treatment and prevention of gastrointestinal infectious diseases.

RESUMO

Testicular sex cord-stromal tumors are clonal neoplasms, with the majority being of Leydig cell followed by Sertoli cell origins. In Leydig cell tumors, adipocytic differentiation has been previously reported as a possible distinguishing feature, which has not been reported in other sex cord-stromal tumors. Herein, we report a case of a 48-year-old man who presented with an incidentally discovered 1.1 cm testicular mass, for which he underwent partial orchiectomy. Microscopically, the tumor showed features consistent with sex cord-stromal tumor with strong and diffuse nuclear and cytoplasmic reaction for B-catenin immunohistochemistry, supporting the diagnosis of Sertoli cell tumor. A novel adipocytic differentiation, reported previously in Leydig cell tumors, was present in this tumor.

RESUMO

Background and Objective: The COVID-19 pandemic response overwhelmed health systems, disrupting other services, including maternal health services. The disruptive effects on the utilization of maternal health services in low-resource settings, including Nigeria have not been well documented. We assessed maternal health service utilization, predictors, and childbirth experiences amidst COVID-19 restrictions in a rural community of Kumbotso, Kano State, in northern Nigeria. Methods: Using an explanatory mixed methods design, 389 mothers were surveyed in January 2022 using validated interviewer-administered questionnaires, followed by in-depth interviews with a sub-sample (n=20). Data were analyzed using logistic regression models and the framework approach. Results: Less than one-half (n=165, 42.4%) of women utilized maternal health services during the period of COVID-19 restrictions compared with nearly two-thirds (n=237, 65.8%) prior to the period (p<0.05). Non-utilization was mainly due to fear of contracting COVID-19 (n=122, 54.5%), clinic overcrowding (n=43, 19.2%), transportation challenges (n=34, 15.2%), and harassment by security personnel (n=24, 10.7%). The utilization of maternal health services was associated with participant's post-secondary education (aOR=2.06, 95% CI:1.14- 11.40) (p=0.02), and employment type (civil service, aOR=4.60, 95% CI: 1.17-19.74) (p<0.001), business aOR=1.94, 95% CI:1.19- 4.12) (p=0.032) and trading aOR=1.62, 95% CI:1.19-2.94) (p=0.04)). Women with higher household monthly income (≥ N30,000, equivalent to 60 US Dollars) (aOR=1.53, 95% CI:1.13-2.65) (p=0.037), who adhered to COVID-19 preventive measures and utilized maternal health services before the COVID-19 pandemic were more likely to utilize those services during the COVID-19 restrictions. In contrast, mothers of higher parity (≥5 births) were less likely to use maternal health services during the lockdown (aOR=0.30, 95% CI:0.10-0.86) (p=0.03). Utilization of maternal services was also associated with partner education and employment type. Conclusion and Global Health Implications: The utilization of maternal health services declined during the COVID-19 restrictions. Utilization was hindered by fear of contracting COVID-19, transport challenges, and harassment by security personnel. Maternal and partner characteristics, adherence to COVID-19 preventive measures, and pre-COVID maternity service utilization influenced attendance. There is a need to build resilient health systems and contingent alternative service delivery models for future pandemics.

RESUMO

Well-differentiated/dedifferentiated liposarcoma (WDLPS/DDLPS) represent a significant number of sarcomas arising within the paratesticular region. DDLPS is notorious for a broad histologic spectrum, but epithelioid morphology is rare. Herein, we describe a unique case of paratesticular DDLPS with prominent epithelioid features and molecular confirmation. The patient is 71-year-old-male who presented with multiple paratesticular masses. Morphologic review of the resection specimen revealed a biphasic adipocytic neoplasm consistent with DDLPS. Additionally, epithelioid foci with acinar and nested architecture and focal keratin expression were noted. These areas raised the possibility of a secondary neoplasm including sex cord stromal tumor, germ cell tumor, and paraganglioma. However, MDM2 immunohistochemistry and FISH showed these areas to express MDM2 and exhibit MDM2 amplification, respectively, confirming that they represented a component of DDLPS. This case further highlights the morphologic diversity of DDLPS as well as the utility of MDM2 studies.
