RESUMO

BACKGROUND: Foodborne diseases affect nearly 600 million people each year, that is, one in every ten people, and their outbreaks are most common in low- and middle-income countries, particularly in Africa. This study investigated the food safety practices among raw meat handlers and the microbial quality of the meat from the butchery shops in Kumasi Abattoir, Ghana. METHODS: This study employed a descriptive cross-sectional study and collected quantitative data on factors associated with food safety and hygienic practices among raw meat handlers and the microbial quality of the raw meat using a structured questionnaire and standard laboratory methods, respectively. The study used all 50 beef vending shops in the butchery for questionnaire aspect and fresh beef samples were obtained from 10 vendors in the butchery shop. Appropriate methods were followed to analyse questionnaire data and meat samples. RESULTS: Most of the butchers (72%) were between the ages of 31 and 45, and they were predominantly Muslims (68%). Most of the respondents (48%) had basic education. All the respondents had food safety certificates from the local authority but needed adequate knowledge of meat safety. Most respondents (90%) handled meat and money with the same bare hands, thus contaminating the meat. The study showed that the maximum Total Viable Count (TVC), Total Staphylococcus Count (TSC), and Total Escherichia coli Count (TEC) were 5.60, 4.39 and 5.13 cfu/g, respectively. The study also revealed that all the meat samples were Salmonella species-free. CONCLUSIONS: Microorganisms in raw beef indicate a public health hazard. It gives a signal of a possible occurrence of food-borne intoxication and infection if not controlled. Environmental health officers in the Greater Kumasi area should organize food safety training and educate raw meat handlers on the importance of food safety and its consequences.

RESUMO

BACKGROUND: Between 2018 and 2022, Nigeria experienced continuous transmission of circulating vaccine-derived type 2 poliovirus (cVDPV2), with 526 cases of cVDPV2 poliomyelitis detected in total and approximately 180 million doses of monovalent type 2 oral poliovirus vaccine (mOPV2) and 450 million doses of novel type 2 oral poliovirus vaccine (nOPV2) delivered in outbreak response campaigns. Inactivated poliovirus vaccine (IPV) was introduced into routine immunisation in 2015, with a second dose added in 2021. We aimed to estimate the effectiveness of nOPV2 against cVDPV2 paralysis and compare nOPV2 effectiveness with that of mOPV2 and IPV. METHODS: In this retrospective case-control study, we used acute flaccid paralysis (AFP) surveillance data in Nigeria from Jan 1, 2017, to Dec 31, 2022, using age-matched, onset-matched, and location-matched cVDPV2-negative AFP cases as test-negative controls. We also did a parallel prospective study from March, 2021, using age-matched community controls from the same settlement as the cases. We included children born after May, 2016, younger than 60 months, for whom polio immunisation history (doses of OPV from campaigns and IPV) was reported. We estimated the per-dose effectiveness of nOPV2 against cVDPV2 paralysis using conditional logistic regression and compared nOPV2 effectiveness with that of mOPV2 and IPV. FINDINGS: In the retrospective case-control study, we identified 509 cVDPV2 poliomyelitis cases in Nigeria with case verification and paralysis onset between Jan 1, 2017, and Dec 31, 2022. Of these, 82 children were excluded for not meeting inclusion criteria, and 363 (85%) of 427 eligible cases were matched to 1303 test-negative controls. Cases reported fewer OPV and IPV doses than test-negative controls (mean number of OPV doses 5·9 [SD 4·2] in cases vs 6·7 [4·3] in controls; one or more IPV doses reported in 95 [26%] of 363 cases vs 513 [39%] of 1303 controls). We found low per-dose effectiveness of nOPV2 (12%, 95% CI -2 to 25) and mOPV2 (17%, 3 to 29), but no significant difference between the two vaccines (p=0·67). The estimated effectiveness of one IPV dose was 43% (23 to 58). In the prospective study, 181 (46%) of 392 eligible cases were matched to 1557 community controls. Using community controls, we found a high effectiveness of IPV (89%, 95% CI 83 to 93, for one dose), a low per-dose effectiveness of nOPV2 (-23%, -45 to -5) and mOPV2 (1%, -23 to 20), and no significant difference between the per-dose effectiveness of nOPV2 and mOPV2 (p=0·12). INTERPRETATION: We found no significant difference in estimated effectiveness of the two oral vaccines, supporting the recommendation that the more genetically stable nOPV2 should be preferred in cVDPV2 outbreak response. Our findings highlight the role of IPV and the necessity of strengthening routine immunisation, the primary route through which IPV is delivered.

RESUMO

Chimeric Antigen Receptor T-cell (CAR-T) therapy has revolutionized the treatment of patients with hematologic malignancies, yet treatment may coincide with the potential for life-threatening toxicities. Currently, no studies have investigated how oncologists communicate with patients about CAR-T therapy or what patients and their caregivers want to know prior to consenting for CAR-T therapy. This study characterizes the content of oncologist communication with patients and caregivers about the risks and benefits of CAR-T therapy and explore the information preferences of patients and their caregivers about CAR-T therapy. We conducted a multimethod study of 20 patients with hematologic malignancies referred for CAR-T therapy at the Massachusetts General Hospital and 10 caregivers. We audio recorded the initial outpatient visit with the oncologist to review and sign consent for CAR-T therapy. We subsequently surveyed patients and caregivers about information gaps that remained after consent. We then interviewed patients and caregiver about their perceptions of oncologist communication and information preferences after the consent visit, 1 month, and 3 months post-CAR-T therapy treatment. Qualitative data analysis was conducted using the framework approach. Six major themes regarding communication about CAR-T therapy were identified: (1) oncologists create a narrative of power and innovation about CAR-T therapy, (2) oncologists set clear expectations regarding CAR-T therapy, (3) oncologists preferentially discuss positive treatment outcomes and less frequently address treatment failures or uncertainties, (4) oncologists couple their discussion about risks of CAR-T therapy with assurances about risk mitigation strategies, (5) oncologists engage in empathetic communication throughout the consent visit, (6) patients and caregivers vary in their preferences regarding communication about CAR-T therapy but largely favor a positive discourse during the consent visit and (7) patients who completed CAR-T therapy and their caregivers report significant knowledge gaps during and after treatment. Overall, patients and caregivers felt well informed about CAR T-therapy yet identified communication gaps regarding, advanced care planning, treatment failure and treatment toxicities. A predominantly positive discourse between patients, caregivers, and oncologists around CAR-T therapy leaves patients and caregivers with significant knowledge gaps about negative outcomes. Further research is needed to help oncologists communicate about treatment uncertainties and help patients and their caregivers prepare for negative outcomes of CAR-T therapy.

RESUMO

E-waste processing sites abound with potentially toxic elements (PTE) that negatively affect the environment and human health. The study determined the presence of selected PTE (Cu, Zn, Pb, Hg, and Al) and their spatial distribution in an e-waste processing site in a developing country setting. pH, moisture, organic matter/carbon, and particle size were determined in 30 soil samples. The spatial position of each sampling point was picked with a GPS device, and the area was mapped in a GIS environment. The concentrations of PTE were determined with an atomic absorption spectrophotometer. Findings from the study indicate that the soil is polluted with PTE, rich in organic carbon/matter but has low pH. The Geoaccumulation Indices ranged from unpolluted (Al) to strongly/extremely polluted (Cu). Pollution Load Index showed about 77 % of the samples as extremely/heavily polluted, 10 % as heavily polluted, and 13 % as moderately polluted. Contamination Factors of Zn, Pb, and Cu were very high but considerably low for Hg and Al. Regular monitoring and remediation are required for the soil to be restored and put into productive use.

RESUMO

Parental involvement in childhood cancer care is of utmost importance, but the understanding of parental recognition, appraisal, and reactions to childhood cancer in settings such as Ghana is limited. We conducted an empirical phenomenological study to explore these aspects among Ghanaian parents. Twenty parents were purposively sampled to participate in semi-structured interviews between June and September 2022. All interviews were transcribed and analysed using an inductive thematic approach. We found that parents recognised symptoms through personal observation and their child's self-report, often perceiving them as non-severe. Emotional reactions upon receiving their child's cancer diagnosis included psychological distress, fear, doubts, and confusion. Enduring emotions experienced by parents were fears of disease recurrence and impending death of their child. Parents assumed the role of nurses at home, monitoring therapy effects, managing pain and symptoms, and dressing wounds. In conclusion, parents in Ghana play a crucial role in the recognition, diagnosis, and treatment pathways of childhood cancer. To enhance their ability to recognise symptoms and take timely actions, it is recommended to implement media programs and health education initiatives targeting parents.

RESUMO

BACKGROUND: Patients with acute myeloid leukemia (AML) experience a substantial decline in quality of life (QoL) and mood during their hospitalization for intensive chemotherapy, yet few interventions have been developed to enhance patient-reported outcomes during treatment. METHODS: We conducted a pilot randomized trial (ClinicalTrials.gov identifier NCT03372291) of DREAMLAND, a psychological mobile application for patients with a new diagnosis of AML who are receiving intensive chemotherapy. Patients were randomly assigned to DREAMLAND or usual care. DREAMLAND included four required modules focused on: (1) supportive psychotherapy to help patients deal with the initial shock of diagnosis, (2) psychoeducation to manage illness expectations, (3) psychosocial skill-building to promote effective coping, and (4) self-care. The primary end point was feasibility, which was defined as ≥60% of eligible patients enrolling and 60% of those enrolled completing ≥60% of the required modules. We assessed patient QoL (the Functional Assessment of Cancer Therapy-Leukemia), psychological distress (the Hospital Anxiety and Depression Scale and the Patient Health Questionnaire-9), symptom burden (the Edmonton Symptom Assessment Scale), and self-efficacy (the Cancer Self-Efficacy Scale) at baseline and at day 20 after postchemotherapy. RESULTS: We enrolled 60 of 90 eligible patients (66.7%), and 62.1% completed ≥75% of the intervention modules. At day 20 after chemotherapy, patients who were randomized to DREAMLAND reported improved QoL scores (132.06 vs. 110.72; p =.001), lower anxiety symptoms (3.54 vs. 5.64; p = .010) and depression symptoms (Hospital Anxiety and Depression Scale: 4.76 vs. 6.29; p = .121; Patient Health Questionnaire-9: 4.62 vs. 8.35; p < .001), and improved symptom burden (24.89 vs. 40.60; p = .007) and self-efficacy (151.84 vs. 135.43; p = .004) compared with the usual care group. CONCLUSIONS: A psychological mobile application for patients with newly diagnosed AML is feasible to integrate during hospitalization for intensive chemotherapy and may improve QoL, mood, symptom burden, and self-efficacy.

RESUMO

BACKGROUND: Chimeric antigen receptor (CAR) T-cell is potentially curative therapy for patients with hematologic malignancies but can cause life-threatening toxicities. Data on perceptions of prognosis and psychological distress are lacking. METHODS: The authors conducted a cross-sectional study of patients receiving CAR-T. Before hospitalization for CAR-T, patients completed assessments of quality of life (QOL) (Functional Assessment of Cancer Therapy-General), anxiety and depression symptoms (Hospital Anxiety and Depression Scale) and post-traumatic stress disorder symptoms (Post-Traumatic Stress Checklist). Patients also completed the Prognostic Awareness Impact Scale (PAIS), which measures three domains: cognitive understanding of prognosis, emotional coping with prognosis, and adaptive response. RESULTS: A total of 71.8% (102 of 142) of eligible patients were enrolled. A total of 34% of patients reported that their oncologist said their cancer is curable and 64% reported there was >50% chance of cure. Overall, 26%, 30%, and 21% of patients reported clinically significant depression, anxiety, and posttraumatic stress disorder (PTSD) symptoms, respectively. We found no association between patients' cognitive understanding of prognosis and QOL or mood. Higher emotional coping with prognosis was associated with better QOL (Β = 0.72; SE = 0.10; p = <.001) and lower depression (Β = -0.17; SE = 0.02; p = <.001), anxiety (Β = -0.21; SE = 0.02; p = <.001), and PTSD (Β = -0.43; SE = 0.06; p = <.001) symptoms. Higher adaptive response was associated with better QOL (Β = 0.19; SE = 0.09; p = .028) and lower depression (Β = -0.05; SE = 0.02; p = .023), anxiety (Β = -0.09; SE = 0.02; p = <.001), and PTSD (Β = -0.19; SE = 0.05; p = <.001) symptoms. CONCLUSIONS: Patients undergoing CAR-T report overly optimistic perception of their prognosis and have high rates of psychological distress. Higher emotional coping with prognosis and adaptive response were associated with better QOL and less psychological distress, underscoring the need to develop interventions to promote coping with this treatment. PLAIN LANGUAGE SUMMARY: Patients undergoing chimeric antigen receptor T-cell therapy experience report overly optimistic perceptions of their prognosis and have high rates of psychological distress. Notably, higher emotional coping with prognosis and adaptive response were associated with better quality of life and less psychological distress.

RESUMO

Caregivers of patients with hematologic malignancies undergoing hematopoietic stem cell transplantation (HSCT) must cope with substantial caregiving burden, high rates of psychological distress, and diminished quality of life (QOL). However, data describing coping strategies before HSCT and the association between coping, QOL, and psychological outcomes in this population are lacking. We conducted a secondary analysis of data collected during a multisite randomized clinical trial of a supportive care intervention in HSCT recipients and their caregivers. Caregivers completed the Brief COPE, Hospital Anxiety and Depression Scale, and the Caregiver Oncology Quality of Life Questionnaire to measure coping strategies, psychological distress, and QOL, respectively. We grouped coping into 2 higher-order domains: approach-oriented (ie, emotional support and active coping) and avoidant (ie, self-blame and denial). We used the median split method to describe the distribution of coping and multivariate linear regression models to assess the relationship between coping and caregiver outcomes. We enrolled 170 caregivers, with a median (range) age of 53 (47-64) years. Most were White (87%), non-Hispanic (96%), and female (77%). Approach-oriented coping was associated with less anxiety (ß = -0.210, P = .003), depression symptoms (ß = -0.160, P = .009), and better QOL (ß = 0.526, P = .002). In contrast, avoidant coping was associated with more anxiety (ß = 0.687, P<.001), depression symptoms (ß = 0.579, P < .001), and worse QOL (ß = -1.631, P < .001). Our findings suggest that coping is related to distress and QOL among caregivers of HSCT recipients even before transplant. Hence, caregivers of patients with hematologic malignancies undergoing HSCT may benefit from resources that facilitate adaptive coping with the demands of caregiving.

RESUMO

'Zero-dose' refers to a person who does not receive a single dose of any vaccine in the routine national immunization schedule, while 'missed dose' refers to a person who does not complete the schedule. These peopleremain vulnerable to vaccine-preventable diseases, and are often already disadvantaged due to poverty, conflict, and lack of access to basic health services. Globally, more 22.7 million children are estimated to be zero- or missed-dose, of which an estimated 3.1 million (∼14 %) reside in Nigeria.We conducted a scoping review tosynthesize recent literature on risk factors and interventions for zero- and missed-dosechildren in Nigeria. Our search identified 127 papers, including research into risk factors only (n = 66); interventions only (n = 34); both risk factors and interventions (n = 18); and publications that made recommendations only (n = 9). The most frequently reported factors influencing childhood vaccine uptake were maternal factors (n = 77), particularly maternal education (n = 22) and access to ante- and perinatal care (n = 19); heterogeneity between different types of communities - including location, region, wealth, religion, population composition, and other challenges (n = 50); access to vaccination, i.e., proximity of facilities with vaccines and vaccinators (n = 37); and awareness about immunization - including safety, efficacy, importance, and schedules (n = 18).Literature assessing implementation of interventions was more scattered, and heavily skewed towards vaccination campaigns and polio eradication efforts. Major evidence gaps exist in how to deliver effective and sustainable routine childhood immunization. Overall, further work is needed to operationalise the learnings from these studies, e.g. through applying findings to Nigeria's next review of vaccination plans, and using this summary as a basis for further investigation and specific recommendations on effective interventions.

RESUMO

Social support is essential to the recovery of patients who have undergone hematopoietic stem cell transplantation (HSCT). We undertook a qualitative study to explore the specific sources and benefits of social support as experienced by HSCT recipients, as well as their unmet social support needs. We conducted semistructured interviews with 25 HSCT recipients recruited from the Dana Farber Cancer Institute's HSCT database. The interviews explored the sources of support that patients receive, the type of assistance social support networks provide to patients, and unmet needs of social support. Interviews were audio-recorded, transcribed, and coded using Dedoose software. The median age of participants was 63 years (range, 22 to 73 years), and 13 (52%) were female, 20 (80%) were white, and 9 (36%) had been diagnosed with acute myelogenous leukemia. Participants reported receiving a majority of support from immediate family and close friends, with the primary benefits of social support including help with essential daily tasks and household chores, and receipt of emotional support. Participants reported occasional support from other patients but highlighted a desire for increased connection with patients who have undergone the same treatment. Participants also communicated a desire for more guidance on how to optimize the support they do receive and the need for more educational resources for caregivers and supporters to enhance understanding of the HSCT process and lessen patient burden. Participants reported relying on support from their family, friends, and other social connections for essential aspects of their recovery and daily living following HSCT. Although there are many benefits from these relationships, patients emphasized the need for more guidance and resources to facilitate post-transplantation aid and support.

RESUMO

Patients with high-risk acute myeloid leukemia (AML) often experience intensive medical care at the end of life (EOL), including high rates of hospitalizations and intensive care unit (ICU) admissions. Despite this, studies examining code status transitions are lacking. We conducted a mixed-methods study of 200 patients with high-risk AML enrolled in supportive care studies at Massachusetts General Hospital between 2014 and 2021. We defined high-risk AML as relapsed/refractory or diagnosis at age ≥60. We used a consensus-driven medical record review to characterize code status transitions. At diagnosis, 86.0% (172/200) of patients were "full code" (38.5% presumed, 47.5% confirmed) and 8.5% had restrictions on life-sustaining therapies. Overall, 57.0% of patients experienced a transition during the study period. The median time from the last transition to death was 2 days (range, 0-350). Most final transitions (71.1%) were to comfort measures near EOL; only 60.5% of patients participated in these last transitions. We identified 3 conversation types leading to transitions: informative conversations focusing on futility after clinical deterioration (51.0%), anticipatory conversations at the time of acute deterioration (32.2%), and preemptive conversations (15.6%) before deterioration. Younger age (B = 0.04; P = .002) and informative conversations (B = -2.79; P < .001) were associated with shorter time from last transition to death. Over two-thirds of patients were "presumed full code" at diagnosis of high-risk AML, and most experienced code status transitions focused on the futility of continuing life-sustaining therapies near EOL. These results suggest that goals-of-care discussions occur late in the illness course for patients with AML and warrant interventions to increase earlier discussions regarding EOL preferences.

RESUMO

The adoption of e-learning in response to COVID-19 is to ensure the continuous development of human capital through alternative means. Nevertheless, the success of e-learning systems depends much on the attitude of the users. This study developed and empirically tested a model to predict antecedents of students' actual usage of e-learning during the COVID-19 period. A synthesis of UTAUT 2, Self Determination Theory and Core Self-Evaluation Theory were employed to examine the behaviour of students using a sample of 1024. PLS-SEM was used to analysed the hypothesised paths in the model. The results revealed that (1) Personality is positively related to behavioural intention (2) Actual usage is positively influenced by motivational factors (3) Behavioural Intention positively mediates the relationship between motivational factors and actual use (4) motivational factors positively mediate the relationship between UTAUT 2 constructs and behavioural intention. The results will guide stakeholders in education, especially e-learning system designers to incorporate personality and motivational factors in the designing of e-learning systems in order to increase the acceptability of the system by students. This study is among the first few attempts to incorporate personality, motivation and UTAUT2 to examine e-learning users' behaviour, especially in Sub-Saharan Africa during the COVID-19 pandemic. This work presents a contemporary perspective of e-learning users' behaviour during the COVID-19 pandemic.

RESUMO

The current COVID-19 pandemic has significantly altered the quantity and composition of waste generated on the African continent. This new phenomenon, coupled with the indiscriminate disposal of used personal protective equipment (PPEs), poses serious challenges to local authorities, most of whom have limited experience or lack the strategy to handle this occurrence. These PPEs, like the face masks, are made up of polymeric materials that are liquid resistant and remain for a long time in the environment after discard. Thus, they are considered as a significant source of plastic pollution in the environment. Notwithstanding the environmental challenges associated with COVID-19, if Africa is to be ready for the expected growth in waste generation and variation in waste composition in the coming century as predicted by the African waste management outlook report in 2018, she has to have a renewed focus and seize the unique opportunities that COVID-19 presents. The continent has to indulge in introspection of its shortfalls in managing waste and consciously make efforts that would ensure social and technological innovation and investment in services and infrastructure in the waste and secondary resources sector than never before seen in Africa. This approach would help the continent achieve its waste management vision of extending regular and reliable waste collection services to all while valorizing waste generated. This critical review paper reveals the silver lining in the dark cloud of the COVID-19 pandemic by highlighting some of the noticeable environmental challenges in Africa due to the current pandemic and elucidating the rare opportunities that African countries can harness to improve the waste management sector.

RESUMO

BACKGROUND: Despite efforts to improve childhood immunization coverage in Nigeria, coverage has remained below the national acceptable level. In December 2019, we conducted an assessment of Missed Opportunities for Vaccination (MOV) in Ondo State, in Southwest Nigeria. The objectives were to determine the magnitude of, explore the reasons for, as well as possible solutions for reducing MOV in the State. METHODS: This was a cross-sectional study using a mixed-methods approach. We purposively selected 66 health facilities in three local government authorities, with a non-probabilistic sampling of caregivers of children 0-23 months for exit interviews, and health workers for knowledge, attitudes, and practices (KAP) surveys. Data collection was complemented with focus group discussions and in-depth interviews with caregivers and health workers. The proportion of MOV among children with documented vaccination histories were determined and thematic analysis of the qualitative data was carried out. RESULTS: 984 caregivers with children aged 0-23 months were interviewed, of which 869 were eligible for inclusion in our analysis. The prevalence of MOV was 32.8%. MOV occurred among 90.8% of children during non-vaccination visits, and 7.3% during vaccination visits. Vaccine doses recommended later in the immunization series were given in a less timely manner. Among 41.0% of health workers, they reported their vaccination knowledge was insufficient. Additionally, 57.5% were concerned about and feared adverse events following immunization. Caregivers were found to have a low awareness about vaccination, and issues related to the organization of the health system were found to contribute towards MOV. CONCLUSIONS: One in three children experienced a MOV during a health service encounter. Potential interventions to reduce MOV include training of health workers about immunization policies and practices, improving caregivers' engagement and screening of vaccination documentation by health workers during every health service encounter.

RESUMO

BACKGROUND: Context-specific evidence of the spectrum of type 2 diabetes (T2D) burden is essential for setting priorities and designing interventions to reduce associated morbidity and mortality. However, there are currently limited data on the burden of T2D complications and comorbidity in sub-Saharan Africa (SSA). METHODS: T2D complications and comorbidities were assessed in 2,784 participants with diabetes enrolled from tertiary health centres and contextualised in 3,209 individuals without diabetes in Nigeria, Ghana and Kenya. T2D complications and comorbidities evaluated included cardiometabolic, ocular, neurological and renal characteristics. FINDINGS: The most common complications/comorbidities among the T2D participants were hypertension (71%; 95% CI 69-73), hyperlipidaemia (34%; 95% CI 32-36), and obesity (27%; 95% CI 25-29). Additionally, the prevalence of cataracts was 32% (95% CI 30-35), diabetic retinopathy 15% (95% CI 13-17), impaired renal function 13% (95% CI 12-15), and erectile dysfunction (in men) 35% (95% CI 32-38). T2D population-attributable fraction for these comorbidities ranged between 6 and 64%. INTERPRETATION: The burden of diabetes complications and comorbidity is substantial in SSA highlighting the urgent need for innovative public health strategies that prioritise promotion of healthy lifestyles for prevention and early detection of T2D. Also needed are strategies to strengthen health care system capacities to provide treatment and care for diabetes complications.

RESUMO

Genome analysis of diverse human populations has contributed to the identification of novel genomic loci for diseases of major clinical and public health impact. Here, we report a genome-wide analysis of type 2 diabetes (T2D) in sub-Saharan Africans, an understudied ancestral group. We analyze ~18 million autosomal SNPs in 5,231 individuals from Nigeria, Ghana and Kenya. We identify a previously-unreported genome-wide significant locus: ZRANB3 (Zinc Finger RANBP2-Type Containing 3, lead SNP p = 2.831 × 10-9). Knockdown or genomic knockout of the zebrafish ortholog results in reduction in pancreatic ß-cell number which we demonstrate to be due to increased apoptosis in islets. siRNA transfection of murine Zranb3 in MIN6 ß-cells results in impaired insulin secretion in response to high glucose, implicating Zranb3 in ß-cell functional response to high glucose conditions. We also show transferability in our study of 32 established T2D loci. Our findings advance understanding of the genetics of T2D in non-European ancestry populations.

RESUMO

Introduction: Waste management is an important developmental issue globally, especially in developing countries like Ghana. A key challenge of waste management in developing countries is sustainable financing. This study assesses the willingness-to-pay, an integral attribute of sustainable financing mechanism for improved solid waste management (SWM) services in Ghana. Methods: A cross-sectional multicenter study was conducted in Ghana from January to August 2017 among 1560 households in four regional capitals in Ghana; Accra, Takoradi, Kumasi, and Tamale. Data were collected by using a structured interview questionnaire. Logistic regression models were used to determine the predictors of willingness-to-pay for SWM services in Ghana. Results: Overall, 53.7% of the households were willing to make additional payment for improved services, with difference across study sites: 54.5%, 53.1%, 61.7%, and 46.6% in Takoradi, Tamale, Accra, and Kumasi, respectively. Willingness-to-pay for improved SWM was predicted by educational level, marital status, type of employment, and region of residence. Compared to women who had no formal education, those having senior high school (aOR (adjusted odds ratio): 2.53; 95% CI: 1.48, 4.30), postsecondary (aOR: 1.97; 95% CI: 1.08, 3.60), and tertiary education (aOR: 3.30; 95% CI: 1.91, 5.69) were associated with higher odds of willingness-to-pay for improved SWM services. Conclusion: This study provides important evidence on important attribute of financing mechanism, willingness-to-pay for improved SWM services. Findings would contribute to efforts at finding sustainable financing mechanism for waste management services in Ghana.

RESUMO

OBJECTIVE: To determine the met need for emergency obstetric care (EmOC) services in three Payams of Torit County, South Sudan in 2015 and to determine the frequency of each major obstetric complication. DESIGN: This was a retrospective cross-sectional study. SETTING: Four primary healthcare centres (PHCCs) and one state hospital in three payams (administrative areas that form a county) in Torit County, South Sudan. PARTICIPANTS: All admissions in the obstetrics and gynaecology wards (a total of 2466 patient admission files) in 2015 in all the facilities designated to conduct deliveries in the study area were reviewed to identify obstetric complications. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was met need for EmOC, which was defined as the proportion of all women with direct major obstetric complications in 2015 treated in health facilities providing EmOC services. The frequency of each complication and the interventions for treatment were the secondary outcomes. RESULTS: Two hundred and fifty four major obstetric complications were admitted in 2015 out of 390 expected from 2602 pregnancies, representing 65.13% met need. The met need was highest (88%) for Nyong Payam, an urban area, compared with the other two rural payams, and 98.8% of the complications were treated from the hospital, while no complications were treated from three PHCCs. The most common obstetric complications were abortions (45.7%), prolonged obstructed labour (23.2%) and haemorrhage (16.5%). Evacuation of the uterus for retained products (42.5%), caesarean sections (32.7%) and administration of oxytocin for treatment of postpartum haemorrhage (13.3%) were the most common interventions. CONCLUSION: The met need for EmOC in Torit County is low, with 35% of women with major obstetric complications not accessing care, and there is disparity with Nyong Payam having a higher met need. We suggest more support supervision to the PHCCs to increase access for the rural population.

RESUMO

OBJECTIVE: The prevalence of obesity varies between ethnic groups. No genome-wide association study (GWAS) for body mass index (BMI) has been conducted in continental Africans. METHODS: We performed a GWAS for BMI in 1,570 West Africans (WA). Replication was conducted in independent samples of WA (n = 1,411) and African Americans (AA) (n = 9,020). RESULTS: We identified a novel genome-wide significant African-specific locus for BMI (SEMA4D, rs80068415; minor allele frequency = 0.008, P = 2.10 × 10-8 ). This finding was replicated in independent samples of WA (P = 0.013) and AA (P = 0.017). Individuals with obesity had higher serum SEMA4D levels compared to those without obesity (P < 0.0001), and elevated levels of serum SEMA4D were associated with increased obesity risk (OR = 4.2, P < 1 × 10-4 ). The prevalence of obesity was higher in individuals with the CT versus TT genotypes (55.6% vs. 22.9%). CONCLUSIONS: A novel variant in SEMA4D was significantly associated with BMI. Carriers of the C allele were 4.6 BMI units heavier than carriers of the T allele (P = 0.0007). This variant is monomorphic in Europeans and Asians, highlighting the importance of studying diverse populations. While there is evidence for the involvement of SEMA4D in inflammatory processes, this study is the first to implicate SEMA4D in obesity pathophysiology.

RESUMO

Previous data obtained in our laboratory suggested that there may be constitutive signaling through the myeloid differentiation primary response gene 88 (Myd88)-dependent signaling cascade in murine mammary carcinoma. Here, we extended these findings by showing that, in the absence of an added Toll-like receptor (TLR) agonist, the myddosome complex was preformed in 4T1 tumor cells, and that Myd88 influenced cytoplasmic extracellular signal-regulated kinase (Erk)1/Erk2 levels, nuclear levels of nuclear factor-kappaB (NFκB) and signal transducer and activator of transcription 5 (STAT5), tumor-derived chemokine (C-C motif) ligand 2 (CCL2) expression, and in vitro and in vivo tumor growth. In addition, RNA-sequencing revealed that Myd88-dependent signaling enhanced the expression of genes that could contribute to breast cancer progression and genes previously associated with poor outcome for patients with breast cancer, in addition to suppressing the expression of genes capable of inhibiting breast cancer progression. Yet, Myd88-dependent signaling in tumor cells also suppressed expression of genes that could contribute to tumor progression. Collectively, these data revealed a multifaceted role for Myd88-dependent signaling in murine mammary carcinoma.
