SARS-CoV-2 seroprevalence and preeclampsia markers in Mozambican pregnant women with perinatal loss

BackgroundSARS-CoV-2 infection during pregnancy is known to be associated with poor pregnancy outcomes, including pre-eclampsia (PE), prematurity, perinatal and maternal mortality. Data on the burden of SARS-CoV-2 infection among pregnant women and their offspring in Sub-Saharan Africa is limited. We aimed to estimate SARS-CoV-2 seroprevalence and determine PE biomarkers in Mozambican pregnant women with perinatal loss.MethodsA cross-sectional study was conducted among women who had a fetal or an early neonatal death at the Maputo Central Hospital (MCH), Mozambique. Anti-SARS-CoV-2 IgG/IgM were determined in maternal and umbilical cord blood and PE biomarkers (sFlt-1 and PIGF) in maternal blood. SARS-CoV-2 RT-PCR was performed in placenta and fetal lung biopsies from participants found to be SARS-CoV-2 seropositive.ResultsA total of 100 COVID-19 unvaccinated women were included in the study from March 2021 to April 2022. Total SARS-CoV-2 antibodies were detected in 68 [68%; 95CI (58 – 76)] maternal and 55 [55%; 95CI (54 – 74)] cord blood samples. SARS-CoV-2 IgM was detected in 18 cord blood samples and a positive placental RT-PCR in three of these participants. The proportion of women with moderate to high sFlt-1/PIGF ratio was higher in SARS-CoV-2 seropositive women than in those seronegative (71.2% vs 28.8%, p = 0.339), although the difference was not statistically significant.ConclusionsSARS-CoV-2 seroprevalence among Mozambican women with perinatal loss was high during the second pandemic year, and there was evidence of vertical transmission in stillbirths. Findings also suggest that maternal SARS-CoV-2 infection may increase the risk of developing PE.

PD-L1 expression in squamous cervical carcinomas of Mozambican women living with or without HIV

Programmed death-ligand 1 (PD-L1) is overexpressed in squamous cervical cancer (SCC) and can be used for targeted immunotherapy. The highest mortality rates of SCC are reported in sub-Saharan Africa, where Human immunodeficiency virus (HIV) prevalence is high. In Mozambique most SCC patients present at advanced stages. Thus, there is a need to introduce new treatment options. However, immunocompromised patients were frequently excluded in previous clinical trials. Our aim was to determine if PD-L1 expression in SCC is as prevalent among women living with HIV (WLWH) as among other patients. 575 SCC from Maputo Central Hospital were included. HIV status was available in 266 (46%) cases PD-L1 expression was scored through tumour proportion score (TPS) and combined positive score (CPS). PD-L1 was positive in 20.1% of the cases (n = 110), TPS (score ≥ 25%) and in 26.3% (n = 144), CPS (score ≥ 1). Stratifying according to the HIV status, WLWH were TPS positive in 16.7%, compared to 20.9%, p = 0.43, and concerning CPS 21.1% versus 28.7%, p = 0.19, respectively. PD-L1 status was not influenced by stage, Ki-67 or p16, CD8 expression influenced only CPS status. Our data indicates that the documented effect of PD-L1 therapy on SCC should be confirmed in randomized clinical trials in an HIV endemic milieu.

A Cross Sectional Study on the Bidirectional Interactions Between Leptospirosis and HIV Infection Among Patients from Maputo Central Hospital, Mozambique.

This study aims to determine the baseline seroprevalence of leptospirosis, a zoonotic and neglected disease, in people living with HIV (PWH) in Maputo, Mozambique, and to evaluate the relationship between selected HIV-related factors that might influence risk of coinfection with leptospirosis, such as degree of immunosuppression, as assessed by CD4 cell count, World Health Organization (WHO) HIV/AIDS clinical stage and antiretroviral therapy (ART) intake. This was a descriptive cross-sectional analysis of 157 PWH, aged over 18 years old, admitted to the Maputo Central Hospital, in Maputo, Mozambique, between March 2020 and October 2021. The study participants were recruited as a convenience sample regardless of the reasons for their admission. We collected sociodemographic and clinical data, including ART and WHO HIV/AIDS clinical stage, and blood for CD4 cell count and detection of Leptospira IgG antibodies using a commercial Kit ab247199 Leptospira IgG ELISA (www.abcam.com/ab247199) with sensitivity and specificity of 100% and 97.3%, respectively. Laboratory testing was performed at the Faculty of Medicine, Eduardo Mondlane University and Laboratory of Clinical Analysis, in Maputo. Participants were aged 18 to 72 years (median age 39 years; SD ± 10.5), the majority were female 100 (63.7%), from urban areas 138 (87.9%), with secondary-level education 80 (51%). The overall seroprevalence of Leptospira IgG antibodies was 40.1%. The median CD4 cell count was 385 cells/µl (02 to 2297; SD ± 378.47). Higher seroprevalence of Leptospira antibodies was found among participants with CD4 cell counts <250 cells/µl (54.8%), WHO HIV/AIDS stage IV (70.2%) and those on ART (92%), though there were no statistically significant differences between groups with and without Leptospira antibodies. Our study confirmed that Leptospira antibodies are highly prevalent in PWH in Maputo; however, Leptospira infection was not associated with the degree of immunosuppression, WHO HIV/AIDS clinical stage, or the use of ART. Our data support the need for routine screening for leptospirosis in PWH in Mozambique. Future studies are warranted to characterize the incidence and outcomes of symptomatic leptospirosis in this patient population and to identify circulating serovars and species in the country and region, as well as the implicated reservoirs.

Evaluating empiric antibiotic prescribing for hospitalized children in Mozambique through the introduction of a quarterly syndromic antibiogram: An implementation science protocol.

Antimicrobials are the most frequently prescribed drug in pediatrics, with an estimated 37% of infants and 61% of hospitalized children having received them. Approximately 20-50% of prescriptions have been shown to be potentially unnecessary or inappropriate. The World Health Organization (WHO) estimates that the continued increase in antimicrobial resistance by the year 2050 will lead to the death of 10 million people per year. This paper describes a protocol to be used in a future study to evaluate the implementation of a quarterly syndromic antibiogram, aimed to improve the use of antibiotics for the treatment of pediatric bacterial infections at the Maputo Central Hospital, Mozambique. This study uses implementation science methods framed by the Dynamic Adaption Process (DAP) and RE-AIM conceptual frameworks to develop a multi-phase, mixed-methods evaluation utilizing qualitative and quantitative approaches. The pediatric inpatient services at HCM consist of approximately 18 physicians and 60 nurses. Additionally, the microbiology laboratory consists of eight laboratory technicians. We anticipate analyzing approximately 9,000 medical records. Qualitative methods include in-depth interviews with clinicians, laboratory technicians, and administrators to explore current knowledge and practices around antibiotic decision making, facilitators and barriers to intervention implementation, as well as acceptability and satisfaction with the intervention roll-out. Qualitative analysis will be performed with NVivo 12 software. Quantitative methods include extracting data from existing records from the pediatric ward of Hospital Central de Maputo (HCM) guided by the RE-AIM framework to explore intervention utilization and other factors influencing its implementation. Quantitative descriptive and inferential statistical analysis will be performed using R Studio statistical software. The findings from this evaluation will be shared with hospital administrators and relevant national policymakers and may be used by the Ministry of Health in deciding to expand this approach to other hospitals. The expected results of this research include the development of standard operating guidelines for the creation, distribution, and use of a quarterly syndromic antibiogram for antibiotic decision making that is informed by local epidemiology. Findings from this study will be used to develop a larger multi-site trial in Mozambique.

Communication strategies used by medical physicians when delivering bad news at the Maputo Central Hospital, Mozambique: a cross-sectional study

BackgroundPhysicians’ communication with patients and their families is important during both the disease diagnosis and prognosis stages and through the follow-up process. Effective physician communication improves patients’ quality of life and satisfaction with care and helps reduce suffering for those newly diagnosed with advanced progressive illnesses. This study aims to identify the communication strategies physicians use in the transition to palliative care and how these professionals perceive their academic and clinical preparation concerning this task.MethodsA cross-sectional and quantitative study. Physicians providing palliative care at the Maputo Central Hospital, Mozambique, were invited to complete a 17-question questionnaire. This questionnaire was based on a Brazilian adaptation of the Setting-Perception-Invitation-Knowledge-Emotions-Strategy (SPIKES) tool, the P-A-C-I-E-N-T-E protocol, with additional questions regarding socio-demographic details and the integration of “communication of bad news” into hospital training.ResultsOf the 121 participants, 62 (51.2%) were male, and 110 (90.9%) were general practitioners, with a median age of 36 years old. They had worked in clinical practice for a median of 8 years and in their current department for three years. The majority of the participants considered that they have an acceptable or good level of bad news communication skills and believed that they do it in a clear and empathic way, paying attention to the patient’s requests and doubts; however, most were not aware of the existing tools to assist them in this task and suggested that delivering bad news ought to be integrated into the undergraduate medical course and included in hospital training.ConclusionsThis study adds to our understanding of physicians’ strategies when communicating bad news in the context of palliative care at one Mozambique hospital. As palliative care is not fully implemented in Mozambique, it is important to use protocols suitable to the country’s healthcare level to improve how doctors deal with patients and their family members.

Cervical cancer in Mozambique: Clinical characteristics, treatment and survival of incident cases admitted to the Oncology Service of Maputo Central Hospital in 2016-2018.

In Mozambique, cervical cancer is the most frequent cancer in women. However, studies about cervical cancer treatment and prognosis are scarce. We describe the clinical characteristics, treatment and survival of patients with cervical cancer admitted to Maputo Central Hospital (MCH) in 2016 to 2018. Sociodemographic, clinical and cancer-related data were retrieved from clinical records of patients admitted to the Oncology Service of the MCH with an incident cervical cancer in 2016 to 2018 (n = 407). The Pathology Service database was used to obtain information regarding pathological diagnosis. Survival data was obtained through the MCH Cancer Registry and clinical records. Odds ratios for the association between patients' characteristics and the diagnosis of advanced stage cancer were computed using logistic regression. Survival analyses were performed using the Kaplan-Meier estimator. A total of 91.2% of the patients were diagnosed with advanced disease (stage IIB-IV) and squamous cell carcinoma was the predominant histological subtype. Most of the patients underwent chemotherapy (93.1%) but <7% were submitted to surgery, radiotherapy or brachytherapy. Those living with HIV had 3.4-fold higher odds of advanced disease. Overall survival was 72.7% (95% confidence interval [CI]: 67.9-77.0) at 1-year and 51.0% (95%CI: 45.3-56.3) at 2-years. Those with early stage (IA-IIA) and asymptomatic at diagnosis had a significantly higher 2-year overall survival. In Mozambique, cervical cancer is diagnosed mostly in advanced stages, resulting in poor prognosis. This highlights the importance of HPV vaccination and screening, to decrease the burden of cervical cancer in this context.

Postpartum hemorrhage in Sub-Saharan Africa—a prospective study in metropolitan Mozambique

BackgroundEstimates indicate approximately ≈500 to 1000 maternal deaths per 100,000 live births in Sub-Saharan Africa (SSA) (vs ≈5-20 in developed countries). Postpartum hemorrhage (PPH) seems a major contributor to maternal mortality (MM), but there are no comprehensive data for the region. ObjectivesAnalyze MM, PPH, and associated risk factors. MethodsWe collected prospective data on MM, PPH, and associated risk factors in metropolitan Mozambique. We recorded consecutive deliveries at the Maputo Central Hospital between February 2019 and January 2021. Data included age, HIV status, parity, delivery mode, notes, vital signs, laboratory values, and fetal parameters. PPH was determined by charted diagnosis, blood loss of >500 mL, transfusion, and/or notes indicating significant bleeding. ResultsOf 8799 deliveries, ≈40% occurred in women residing outside Maputo City (“nonlocal”), with similar demographic characteristics between local and nonlocal women. However, compared with local women, nonlocal women had worse outcomes, including higher rates of MM (1.52% vs 0.78%; P =.0012) and PPH (16.51% vs 12.39%; P <.0001), whereby PPH was strongly associated with MM (adjusted odds ratio = 5.56; P <.0001). Almost all women with uterine atony (≈1%) experienced PPH. For women receiving laboratory tests on admission (drawn only if in distress; local, n = 561; nonlocal, n = 514), both cohorts revealed similar distributions of hemoglobin levels and platelet counts. Prepartum anemia (≈57%) and thrombocytopenia (≈21%) were prominent risk factors for PPH; risk increased with increasing severity and was additive in the presence of both. ConclusionsPPH is a serious problem in Maputo province, a metropolitan area of SSA, portending high MM. Identification of correctable risk factors, including anemia, should catalyze the development of region-specific prevention protocols.

Severe neurocysticercosis in a quaternary hospital from Mozambique: Case series analysis

BackgroundNeurocysticercosis (NCC) is severe and leading global cause of morbidity and mortality. The disease presents with a variety of clinical presentations from focal to diffuse neurological symptoms. Despite being an endemic country, there are no studies describing the clinico-epidemiological characteristics of NCC in Mozambique. Herein, we describe a consecutive cases series of NCC from the national reference Hospital in Maputo, capital of Mozambique. MethodsConsecutive cases of NCC diagnosed during a 3-year period (January/2020–December/2022) were retrieved from the institutional clinical files and imaging database. ResultsSix cases of NCC were identified, with mean age of 43.1 years (range 26–66). Four were males (66.6 %). The median time from the beginning of clinical manifestations to the diagnosis was 6 months (range 3–18 months). All patients presented with severe parenchymal NCC, with seizures (n = 5, 83 %) being the most common manifestation. Other clinical manifestations were dementia (n = 1) and hydrocephalus (n = 1). The imaging showed multiple lesions at different stages, with half (n = 3) of them showing the coexistence of nodular calcified lesions at earlier stages (vesicular, colloidal and granular stages). Patients were treated with anthelminthic drugs, corticosteroids and anticonvulsants and no deaths to report. The 3rd month modified Rankin scale was ≤ 2 in 83 % of patients. ConclusionIn our case series, patients with NCC presented very late, with severe advanced stage disease, with multiple coexistent short and long-term brain lesions. These findings can be explained eventually because of the Maputo Central Hospital being national referral center receiving commonly more severe cases. Studies aiming to clarify the diagnosis pathways/barriers and NCC awareness among medical doctors working at primary and secondary health care level is mandatory to assess the real burden of NCC and implement timely diagnosis and care of patients affected by this neglected disease.

Prevalence and factors related to anaemia in children aged 6–59 months attending a quaternary health facility in Maputo, Mozambique

ABSTRACT Globally, anaemia prevails as a public health issue, being also a concern in Mozambique, where about two-thirds of children 6–59 months of age are affected by this condition. We carried out this study to estimate anaemia prevalence and evaluate structural determinants and haematological parameters association among children aged 6–59 months attending pediatric inpatient and outpatient services in a Quaternary Health Facility in Maputo City Province, Mozambique. We collected data from 637 inpatients or outpatients who attended pediatric consultations at the Maputo Central Hospital. The overall rate of anaemia in children aged 6–59 months was 62.2% (396/637), with 30.9% moderate anaemia (197/637), 23.9% mild anaemia (152/637), and 7.4% severe anaemia (47/637). Among our study participants, critical factors for anaemia were those concerning the age group, child´s caregiver schooling, malaria and size of the liver.

Anemia in children aged 6 to 59 months attending a quaternary health facility in Maputo, Mozambique

Abstract Background Globally, anemia prevails as a public health issue, being also a concern in Mozambique, where about two-thirds of children 6-59 months of age are affected by anemia. We carried out this study to estimate anemia prevalence and evaluate structural determinants and hematological parameters association among children aged 6 to 59 months attending pediatric inpatient and outpatient services in a Quaternary Health Facility in Maputo City Province, Mozambique. Methods From August 2021 to January 2022, we conducted a cross-sectional study at the ‘Maputo Central Hospital’ where we collected data from 397 inpatients or outpatients who attended pediatric consultations. The cut-off values for anemia were: mild (10g/dL≤Hb≤10.9g/dL), moderate (7g/dL≤Hb≤9.9g/dL), severe (Hb &amp;lt; 7.0g/dL). We used SPSS 28.0 software to perform descriptive analyses and Chi-Square tests. Results Our preliminary findings show that the total rate of positive cases was 30.0% moderate anemia (119/397), 23.9% mild anemia (95/397), and 7.3% severe anemia (29/397). Anemia frequencies were higher in male patients unregarding the type (54.2% moderate, 62.1% mild, 67.9% severe). Anemia prevalence was higher among children aged 24-59 months (41.2% moderate, 47.4% mild, 51.7% severe; p &amp;lt; 0.05). The rate of all anemia types was higher in children from rural areas and Maputo City province relative to those from urban areas and other country provinces. The level of education of the child's companion to the consultations was associated with anemia (p ≤ 0,05), with higher rates observed in secondary level education. We observed no association between iron or serum ferritin values to anemia. Key messages • Children aged 24-59 months, children from rural areas, and who are male are more vulnerable to suffering anemia than their peers, thus needing more monitoring during their growth. • Nutritional-anemia-specific interventions targeting the first 1000 days of life may be helpful to its reduction in children.

Environmental bacterial and fungal contamination in high touch surfaces and indoor air of a paediatric intensive care unit in Maputo Central Hospital, Mozambique in 2018

SummaryBackgroundThe hospital environment serves as a reservoir of microorganisms which may be associated with healthcare-associated infections (HCAI). The study of environmental contamination with microorganisms is a method for the assessment of hospital environmental hygiene. We sought to evaluate the environmental colonisation of a national reference hospital unit, using the total aerobic colony count (ACC) and the isolated microorganisms, as assessment tools.MethodsA cross-sectional study was conducted in the Paediatric Intensive Care Unit (PICU) of the Hospital Central de Maputo during a four-week period in 2018. Surfaces and air were sampled before and after room cleaning, using swabs and passive air method. Those samples were processed at the microbiology laboratory where total ACC levels were evaluated, and microorganisms were isolated, identified and assessed for antibiotic susceptibility.DiscussionComparison of the total median ACC of the indoor air (287 cfu/m3 before and 195 cfu/m3 after) and surfaces (0.38 cfu/cm2 before and 0.33 cfu/cm2 after) before and after room cleaning did not show significant differences (P>0.05). Microorganisms of epidemiological importance, including coagulase negative staphylococci (CoNS), Klebsiella pneumoniae and Serratia odorifera were isolated and all of these three were multi-drug resistant (MDR).ConclusionThe results showed controlled contamination levels on high touch surfaces in the patient environment and a high level of contamination of the indoor air suggesting deficiencies in the PICU environmental decontamination process. There was evidence of the presence of fungi and MDR species of epidemiological importance in the context of HCAI.

High-risk lineages among extended-spectrum β-lactamase-producing Escherichia coli from extraintestinal infections in Maputo Central Hospital, Mozambique

Extended-spectrum β-lactamase (ESBL)-producing extraintestinal pathogenic Escherichia coli (ExPEC), particularly high-risk lineages, are responsible for severe infections and increased mortality and hospital costs worldwide, with a major burden in low-income countries. Here we determined the antimicrobial susceptibility and performed whole-genome sequencing of E. coli isolates from extraintestinal infections of patients during 2017-2018 at Maputo Central Hospital (Mozambique). Multidrug resistance was displayed by 71% of isolates (17/24). All isolates resistant to cefotaxime and ceftazidime were positive for ESBL genes (16/24; 67%) and were co-resistant to amoxicillin/clavulanate (14/16; 88%), piperacillin/tazobactam (8/16; 50%), gentamicin (12/16; 75%), trimethoprim/sulfamethoxazole (15/16; 94%) and ciprofloxacin (11/16; 69%). Several major high-risk ExPEC lineages were identified, such as H30Rx-ST131, fimH41-ST131, H24Rx-ST410, ST617, ST361 and ST69 harbouring blaCTX-M-15, and H30R-ST131, ST38 and ST457 carrying blaCTX-M-27. Dissemination of CTX-M transposition units (ISEcp1-blaCTX-M-15-orf477 and ISEcp1-blaCTX-M-27-IS903B) among different sequence types could be occurring through the mobility of IncF plasmids. Additionally, all H24Rx-ST410 isolates carried ISEcp1-mediated blaCMY-2 AmpC and specific mutations in PBP3/OmpC proteins, potentially contributing to carbapenem resistance even in the absence of carbapenemase genes. Genome analysis highlighted a high assortment of ExPEC/UPEC virulence-associated genes mainly involved in adhesion, invasion, iron uptake and secretory systems among isolates, and an ExPEC/EAEC hybrid pathotype (fimH27-ST131_O18-ac:H4) showing the highest virulence gene content. cgMLST showed clonality and closely related isolates, particularly among ST131 and ST410, suggesting hospital-acquired infections and long-term ward persistence. Our study provides new insights into ExPEC clones, urging measures to prevent and contain their diffusion in this hospital and Mozambique.

Risk factors for oesophageal squamous cell carcinoma in Mozambique.

Studies evaluating risk factors for the occurrence of oesophageal squamous cell carcinoma (ESCC) in high-risk regions might contribute to a better understanding of the oesophageal cancer aetiology and incidence variation worldwide. We aimed to quantify the association between alcohol, tobacco and dietary history, and the occurrence of ESCC in Mozambique. A case–control study was conducted at Maputo Central Hospital. Cases (n = 143) were patients with newly diagnosed oesophageal cancer recruited in the Gastroenterology Service. Controls (n = 212) were selected in the Orthopaedic Ward among subjects with pathologies related to trauma. Crude and adjusted odds ratios (ORs), and the corresponding 95% confidence intervals (CI) were computed using non-conditional logistic regression. The risk of ESCC was higher in older participants and lower in those with higher household income. Alcohol drinking (lifetime consumption ≥ 55.1 versus 0 kg ethanol: OR = 5.56; 95% CI: 2.43–12.73) and tobacco smoking (lifetime consumption ≥ 20 versus 0 pack/years: OR=7.26; 95% CI: 1.42–37.17) were associated with increased risk of ESCC. Tea (at least twice daily versus less than daily: OR = 5.09; 95% CI: 2.45–10.58) was also associated with the occurrence of ESCC. No significant differences were observed for fruit and vegetable and for smoked meat or fish consumption. Findings from this study show that in our sample, the occurrence of ESCC is strongly influenced by lifetime consumption of tobacco and alcohol, and with tea drinking. This highlights the importance of preventive measures based on the promotion of healthier lifestyles.

Coping Strategies Used by Patients After Diagnosis Disclosure in the Transition to Palliative Care: A Cross-Sectional Study.

Objectives: The objectives of this study were to identify the coping strategies used by cancer and non-cancer patients with palliative needs, and to verify if there were differences in the coping strategies adopted between sociodemographic groups. Methods: This is a cross-sectional study carried out from September to November 2019, at Maputo Central Hospital, in the units of Medicine, Surgery, Orthopedics, Gynecology and Obstetrics. Eligible patients (n = 94) were included in the study and answered a self-completion scale adapted from the Coping Strategies Inventory by Folkman and Lazarus together with a sociodemographic questionnaire. Results: Our study demonstrates that the most used coping strategies were Social Support, followed by Planful Problem Solving, Escape-Avoidance, and Positive Reappraisal strategies. In addition, significant differences were observed between religious beliefs, with Christians resorting more to coping strategies related to Social Support, Accepting Responsibility and Escape-Avoidance than Evangelicals, and between different levels of education, with greater resort to Social Support, Accepting Responsibility, Planful Problem Solving, and Positive Reappraisal in patients with high education. Conclusions: The results indicate that most of the respondents in this study used more adaptive coping strategies, such as Social Support and Positive Reappraisal, and less avoidant strategies, such as Distancing and Confrontation. There is a need to reinforce positive strategies from health professionals to increase satisfaction, autonomy, and promote patient's quality of life.

Stroke in Maputo central hospital, Mozambique 2019: A glimpse of epidemic or endemicity?

Background: Although not a communicable disease, the term “stroke epidemic” is being used widely in the literature. The “epidemic” of stroke might be due to over the time social transmission of unhealthy activities such as unhealthy diet, physical inactivity, and smoking. The aim of this study is to determine the endemic/epidemic pattern of stroke in Maputo Central Hospital in the first semester of 2019. Methods: A cross-sectional study was carried out collecting secondary data (registered cases) from hospitalized patients with stroke. Data from 2014-18 were used to generate the epidemic thresholds. Four threshold epidemic detection methods were used: mean + 2SD; C-SUM; C-SUM + 1.96SD; and the 3rd quartile. Data from January to June 2019 were used to analyze the 2019 trend over the thresholds. Results: An epidemic pattern of stroke was observed during the first semester of 2019 when 3rd quartile and C-SUM threshold epidemic method was used. This epidemic pattern of stroke was not observed when mean+2SD and C-SUM+1.96SD threshold epidemic method was used. A relatively stable pattern of stroke occurrence with high registered cases was observed during the study period. Conclusions: Stroke is an endemic disease for the Maputo Central Hospital, with an epidemic pattern during the first semester of 2019. Adoption of threshold methods for stroke surveillance might well add value for the control of the stroke epidemics.

Stroke in Maputo central hospital, Mozambique: a cross-sectional study 2014–18

Objective: Stroke is the second leading cause of death worldwide. The prevalence of hypertension (the major risk factor for stroke) in Mozambique increased from 33.1% in 2005 to 38.9% in 2014/2015, although awareness and control remained at very low levels (15% and 3%, respectively). The aim of this study is to characterize the demographic and clinical pattern of stroke in Maputo Central Hospital (MCH), Mozambique. Methods: A cross-sectional hospital-based study was carried out in MCH, collecting secondary data from hospitalized patients with stroke. Using systematic probabilistic sampling, clinical records were used to analyze data for the period 2014-18. Results: Of the 402 clinical records, 53.5% were female. The mean age was 60.68 years (13.98 SD). Around 96% was an acute stroke event, and 91% was first-ever episode. Thirty one percent did not receive a CT scan for confirmation. Of the 247 CT scanned patients, 50.2% were ischemic. The area of middle cerebral artery was affected in 83.4% patients. The most common co-morbidity was hypertension (87.1%). Near 96% of hemorrhagic stroke were associated with hypertension (Ischemic = 78.7%, p &lt; 0.001). The overall case-fatality was 22.9%. Confirmed hemorrhagic stroke patients were 6.47 years younger than ischemic (56.40 vs 62.87 years; p &lt; 0.001). Younger ages and female were associated with clinical improvement (aOR = 0.964; p = 0.002 and aOR = 1.890; p = 0.044, respectively). Hemorrhagic stroke were 56.8 percent points more likely associated with death (aOR = 0.432; p = 0.010). The likelihood of clinical improvement was 20.5 percent points better over the years (aOR = 1.205; p = 0.086) Conclusions: Stroke associated with hypertension is common in MCH, mostly likely due to an increase in hypertension prevalence and extremely low awareness and control. Favorable clinical outcome improved over the years. Efforts for CT scan to all stroke episodes should be emphasized by MCH managers.

Demographic, endoscopic and histological profile of esophageal cancer at the Gastroenterology Department of Maputo Central Hospital from January 2016 to December 2018.

Introductionesophageal cancer is a major public health problem in Mozambique. It is the nineth most common cancer worldwide in terms of incidence (604.000 new cases/year), and sixth in overall mortality (544.076 deaths/year). In Mozambique esophageal cancer was the seventh most common cancer in males and the fifth in females between 1991 and 2008.Methodsit was done a cross-sectional hospital-based epidemiological study, using secondary demographics endoscopic and pathologic features data. A retrospective analysis of the existing information of patients classified as esophageal cancer diagnosed with upper gastrointestinal endoscopy observed from January 1st, 2016 to December 31st, 2018 at the Gastroenterology Service of Maputo Central Hospital. A coding sheet was created a priori, and data analysed in SPSS version 20.Resultsof the 205 cases with complete records where included in the analysis, there was a higher frequency of females with 56.6% (116/205). The average age was 59.5 years with standard deviation of ± 12.9 years. Most of the patients were native of southern Mozambique, with 92.7% (190/205), of which Maputo made up 53.2% (109/205). Regarding race, 99.5% (204/205) were black. The most affected endoscopic location was the middle third with 48.8% (100/205), followed by the lower third with 29.8% (61/205) and the upper third with 21.5% (44/205). Squamous cell carcinoma was the most frequent, with 92.7% (190/205), followed by adenocarcinoma with 4.9% (10/205).Conclusiondue to the high number of observed cases of esophageal cancer, a high degree of clinical suspicion is needed for timely diagnosis and more effective treatment. Updated prevalent studies are needed throughout the country to understand the true impact of esophageal cancer on the Mozambican population.

Polyclonal emergence of MDR Enterobacter cloacae complex isolates producing multiple extended spectrum beta-lactamases at Maputo Central Hospital, Mozambique

Enterobacter spp. are important nosocomial pathogens responsible of a wide variety of infections, mainly due to Extended Spectrum β-Lactamase (ESBL) producing isolates, constituting a global public health issue in terms of clinical treatment and infection control, especially in low-income countries, where last-line treatment is often unavailable and there is weak nosocomial surveillance. In this study, we conducted a phenotypic and molecular characterization of 8 clinical Enterobacter spp. strains, isolated from patient’s blood in three hospitals in Mozambique. Isolates were identified by MALDI-TOF and antimicrobial Susceptibility Testing was performed by VITEK 2 system. Half of isolates were analyzed by PCR for β-lactamases genes, other isolates by Whole Genome Sequencing. We identified all isolates as Enterobacter cloacae complex (ECC), those from Maputo Central Hospital were polyclonal, multidrug resistant (5/8), and ESBL producers (50%), carrying blaCTX-M-15 and different assortment of blaSHV-12, blaTEM-1B and blaOXA-1, and AmpCs blaCMH-3, blaACT-7 and blaACT-9 genes. Resistance determinants linked to fluoroquinolone (aac(6')Ib-cr and qnrB1) and others antimicrobials were also found. Notably, one isolate showed phenotypically resistance to colistin, while another colistin susceptible isolate carried a silent mcr-9 gene. ECC nosocomial surveillance is urgently needed to contain and prevent the dissemination of ESBLs producing clones, and mcr-9 spread to other Enterobacteriaceae.

Circumstances and Consequences of Violence-Related Injuries Presenting at Hospital. A Study at the Pediatric Emergency and Forensic Medicine Units of Maputo Central Hospital, Mozambique

Rates of violence against children are high in Sub-Saharan Africa and information is scarce on the resulting injuries. This study investigates sex-related differences in the circumstances and consequences of sexual and physical violence in the Mozambican context. Hospital records from 2019 at the pediatric emergency and forensic medicine units of Maputo Central Hospital were scrutinized using a standardized form. Of the 321 cases identified, 60% resulted from sexual violence. Girls represented 86.4% of the victims of sexual violence and boys, 66.1% of those from physical violence. Being injured in a familiar environment and by a parent, a relative, or someone known was strikingly common. The injury pattern varied by form of violence and sex of the child. About half of the injuries sustained by physical violence were minor/superficial. Severe injuries requiring hospitalization (33% in total) and some specialized care (27% in total) were mainly sustained by girl victims of sexual violence. While circumstances and consequences of violence-related injuries have several similarities, being severely injured is more typical of girl victims of sexual violence. Besides medical care, hospital services in Mozambique must be prepared to offer pediatric victims of violence the necessary social care.
