RESUMO

Growth faltering in children (low length for age or low weight for length) during the first 1,000 days of life (from conception to 2 years of age) influences short-term and long-term health and survival1,2. Interventions such as nutritional supplementation during pregnancy and the postnatal period could help prevent growth faltering, but programmatic action has been insufficient to eliminate the high burden of stunting and wasting in low- and middle-income countries. Identification of age windows and population subgroups on which to focus will benefit future preventive efforts. Here we use a population intervention effects analysis of 33 longitudinal cohorts (83,671 children, 662,763 measurements) and 30 separate exposures to show that improving maternal anthropometry and child condition at birth accounted for population increases in length-for-age z-scores of up to 0.40 and weight-for-length z-scores of up to 0.15 by 24 months of age. Boys had consistently higher risk of all forms of growth faltering than girls. Early postnatal growth faltering predisposed children to subsequent and persistent growth faltering. Children with multiple growth deficits exhibited higher mortality rates from birth to 2 years of age than children without growth deficits (hazard ratios 1.9 to 8.7). The importance of prenatal causes and severe consequences for children who experienced early growth faltering support a focus on pre-conception and pregnancy as a key opportunity for new preventive interventions.

RESUMO

Low- and middle-income countries (LMIC) face unique challenges with regard to the establishment of robust pharmacovigilance systems capable of generating data to inform healthcare policy and practice. These include the limited integration and reliability of pharmacovigilance systems across LMIC despite recent efforts to harmonize pharmacovigilance rules and regulations in several regional economic communities. There are particular challenges relating to the need to translate reporting tools into numerous local languages and the low numbers of healthcare providers relative to number of patients, with very short consultation times. Additional factors frequent in LMIC include high uptake of herbal and traditional medication, mostly by self-medication; disruptive political conflicts jeopardizing fragile systems; and little or no access to drug utilization data, which makes it difficult to reliably estimate the true risks of medicines use. Pharmacovigilance activities are hindered by the scarcity of well-trained personnel with little or no budgetary support from national governments; high turnover of pharmacovigilance staff whose training involves a substantial amount of resources; and little awareness of pharmacovigilance among healthcare workers, decision makers and consumers. Furthermore, little collaboration between public health programmes and national medicines regulatory authorities coupled with limited investment in pharmacovigilance activities, especially during mass drug administration for neglected tropical diseases and mass vaccinations, produces major challenges in establishing a culture where pharmacovigilance is systematically embedded. Very low spontaneous reporting rates with poor quality reports hinders robust signal detection analyses. This review summarises the specific challenges and areas of progress in pharmacovigilance in LMIC with special focus on the situation in Africa.

RESUMO

BACKGROUND: Empirical antibiotic strategies in the treatment of chronic osteomyelitis should ideally be based on local microbiological antibiograms. OBJECTIVES: To review the antibiogram profiles of bacterial isolates of patients undergoing surgical treatment for chronic osteomyelitis and identify the most appropriate empirical antibiotic strategy. METHODS: A retrospective review of clinical records and microbial culture reports was performed for all patients who underwent treatment for chronic osteomyelitis at two orthopaedic units in Western Cape Province, South Africa, between March 2016 and December 2019. Reported antibiotic susceptibility data were used to predict the potential efficacy of different empirical antibiotic regimens, according to underlying aetiology (fracture related, contiguous, haematogenous). RESULTS: Two hundred patients with chronic osteomyelitis of the appendicular skeleton underwent surgical management. Antibiogram profiles for 218 organisms, isolated from 169 patients, were evaluated. Staphylococcus aureus (41%) and Enterobacterales (30%) were the most common organisms isolated. The combinations of meropenem plus vancomycin, and piperacillin-tazobactam plus amikacin plus vancomycin, as empirical postoperative antibiotics would both effectively treat 78% of chronic osteomyelitis cases overall. The most effective practical oral combinations were co-amoxiclav plus ciprofloxacin (61%) and co-trimoxazole plus ciprofloxacin (61%). CONCLUSIONS: This study reports antibiogram profiles in the developing-world setting that could potentially guide empirical antibiotic choices in the management of chronic osteomyelitis.

RESUMO

Mycobacterium tuberculosis (M.tb) is the causative agent of tuberculosis (TB), an infectious disease that leads to numerous deaths worldwide. Malnutrition, smoking, alcohol abuse, Human Immunodeficiency Virus infection, and diabetes are some of the most important risk factors associated with TB development. At present, it is necessary to conduct studies on risk factors to establish new effective strategies and combat this disease. Malnutrition has been established as a risk factor since several years ago; although there is in vitro experimental evidence that reveals the importance of micronutrients in activating the immune response against M.tb, evidence from clinical trials is controversial. Currently, nutritional assessment is recommended in all TB patients upon diagnosis. However, there is insufficient evidence to indicate micronutrient supplementation as adjuvant therapy or prophylactic to prevent micronutrient depletion. Strengthening the interaction between basic and clinical research is necessary to carry out studies that will help establish adjuvant therapies to improve outcomes in TB patients. In this review, we discuss the experimental evidence, provided by basic research, regarding micronutrients in the TB field. However, when these studies are applied to clinical trials, the data are inconsistent, indicating that still missing mechanisms are necessary to propose alternatives to the treatment of TB patients.

RESUMO

PURPOSE OF REVIEW: Undernutrition, including micronutrient deficiencies, continues to plague children across the world, particularly in low and middle-income countries (LMICs). The situation has worsened alongside the SARS-CoV-2 pandemic because of major systemic disruptions to food supply, healthcare, and employment. Large-scale food fortification (LSFF) is a potential strategy for improving micronutrient intakes through the addition of vitamins and minerals to staple foods and improving the nutritional status of populations at large. RECENT FINDINGS: Current evidence unquestionably supports the use of LSFF to improve micronutrient status. Evidence syntheses have also demonstrated impact on some functional outcomes, including anemia, wasting, underweight, and neural tube defects, that underpin poor health and development. Importantly, many of these effects have also been reflected in effectiveness studies that examine LSFF in real-world situations as opposed to under-controlled environments. However, programmatic challenges must be addressed in LMICs in order for LSFF efforts to reach their full potential. SUMMARY: LSFF is an important strategy that has the potential to improve the health and nutrition of entire populations of vulnerable children. Now more than ever, existing programs should be strengthened and new programs implemented in areas with widespread undernutrition and micronutrient deficiencies.

RESUMO

PURPOSE: This systematic review aims to summarize factors that influence the quality of life (QOL) of advanced cancer patients in palliative care (PC) in developing countries. Understanding this context in developing countries milieu is necessary; however, this outcome is rarely reported. METHODS: Following the PRISMA guidelines, the electronic databases MEDLINE, Embase, CINAHL, and Web of Science were systematically searched using the search terms: QOL, cancer, PC, and names of all developing countries. Studies with less than ten subjects, qualitative or pilot studies, reviews, conference abstracts, and that reported validation of QOL questionnaires were excluded. RESULTS: Fifty-five studies from 15 developing countries in the African (n = 5), Latin America and the Caribbean (n = 10), and Asian (n = 40) region were included in the narrative synthesis. 65.4% were cross-sectional, 27.3% were cohort studies, 7.3% were RCTs or quasi-experimental studies. Around 30 QOL factors were studied with 20 different types of QOL instruments. Advanced cancer patients who were older, married/ever married, participated in additional care within PC, used complementary and alternative medicine (CAM), and practiced spirituality/religiosity showed higher QOL score. Low educational level and high depression were associated with a lower QOL. CONCLUSION: Various factors affect QOL among cancer patients in PC. Patients valued the use of CAMs; however, the quality and safety aspects should be properly addressed. Important factors that influenced the QOL score were social and spiritual support. While there is a general need to develop PC strategies further, recognizing patients' needs should be prioritized in national cancer programs.

RESUMO

BACKGROUND: Splenic marginal zone lymphoma (SMZL) is a rare lymphoid B-cell malignant neoplasm with primary involvement of the spleen. It is a chronic disease, of indolent behavior and prolonged survival. However, 25% of cases have higher biological aggressiveness, propensity for histological transformation to high grade B-cell non-Hodgkin lymphoma and shortened survival. Recognition of these cases of reserved outcome is important for selecting a risk-adapted therapeutic approach in a resource-poor settings. METHODS: We described clinical and epidemiological characteristics, survival analysis and prognostic factors in a retrospective cohort of 39 SMZL patients, treated in Latin America. RESULTS: We observed a predominance of female (71.8%), median age of 63 years and higher incidence of B symptoms (56.4%) and extra-splenic involvement (87.1%) than in European and North-American series. With a median follow-up of 8.7 years (0.6-20.2 years), estimated 5-year overall survival (OS) and progression-free survival (PFS) were 76.9% and 63.7%, respectively. Factors with adverse prognostic impact on OS and PFS were Hb < 100 g/L, platelet count < 100 x 109/L, albumin < 3.5 g/dL, LDH > 480 U/L and high-risk Arcaini and SMZL/WG scores. Despite a relative low number of patients, no superiority was observed among the therapeutic regimens used including rituximab monotherapy, splenectomy and cytotoxic chemotherapy. CONCLUSION: Therefore, in resource-poor settings, where access to immunotherapy is not universal for all SMZL patients, we suggest that first-line should consist on rituximab therapy for elderly patients or with high surgical risk or with at least 1 risk factor identified in our study. Remainders can be safely managed with splenectomy.

RESUMO

OBJECTIVE: High stillborn rates are a concern in developing countries. Hence, this article aims to describe the sociocultural norms contributing to the high number of stillbirths as perceived by mothers, significant others, midwives and records of the Pregnancy Problem Identification Programme (PPIP). DESIGN & SETTING: A multimethod qualitative descriptive study was conducted in a district in the Free State, South Africa. Each of the five sub-districts has a district hospital where most pregnant women give birth. Eighty per cent of the community is black of which about a quarter live in poor conditions below the poverty line. PARTICIPANTS: The first author conducted unstructured in-depth interviews with 36 mothers and their significant other who gave birth to a stillborn. She also extracted relevant data from the PPIP record of each mother. A skilled moderator conducted three focus group interviews with a convenience sample of midwives. The data were inductively analysed to identify subthemes under the central theme of social norms. KEY CONCLUSIONS: The authors concluded that traditional practices, traditional role players (traditional healer, mother-in-law, partner), abuse, and prescriptive social norms might contribute to stillbirths. Pregnant women are oppressed as they adhere to traditional social norms and are unable to make independent, informed healthcare decisions. The midwives, who are mostly female, may find it difficult to empower pregnant women because they are under the same social oppression as their clients. IMPLICATIONS FOR PRACTICE: It is imperative that healthcare providers consider social determinants of health, including social norms, when providing healthcare, especially to pregnant women as some social practices may have detrimental outcomes for the mother and/or baby.

RESUMO

This review addresses the prevalence of zinc deficiency in Low- and Middle-income Countries (LMICs) and assesses the available strategies for its alleviation. The paucity of national-level data on the zinc deficiency in LMICs is partially a result of the lack of a reliable biomarker. Zinc deficiency appears to be a public health problem in almost all the LMICs, irrespective of the recommended indicators (plasma zinc concentration, dietary zinc adequacy and stunting prevalence) used. Based on plasma/serum zinc concentration (PZC), which is the most appropriate indicator at present, the prevalence of zinc deficiency in LMICs is of concern. Among the 25 countries for which national PZC data were available, 23 had a zinc deficiency prevalence of >20% for at least one physiological group. Zinc supplementation is largely restricted as an adjunct therapy for diarrhoea management in children, and the best platform and the most effective way of preventive zinc supplementation delivery remains to be established. Impact assessment for current zinc fortification programmes in LMICs and the effectiveness of zinc supplementation as part of a multi-micronutrient powder is to be determined. Dietary diversification, though promising for LMICs, is in the nascent stages of development at present. Inclusion of meat and animal products can be an important way of improving zinc status. Programmatic experience with the promotion of home processing techniques to increase absorbable zinc in the diet is lacking. Conventional biofortification techniques are gaining recognition in LMICs; however, transgenic biofortification as a strategy remains controversial.

RESUMO

Heterogeneity of effects produced by performance-based incentives (PBIs) at different levels of care provision is not well understood. This study analyzes effect heterogeneities between different facility types resulting from a PBI program in Malawi. Identical PBIs were applied to both district hospitals and health centers to improve the performance of essential health services provision. We conducted two complementary quasi-experiments comparing all 17 interventions with 17 matched independent control facilities (each 12 health centers, five hospitals). A pre- and post-test design with difference-in-differences analysis was used to estimate effects on 14 binary quality indicators; interrupted time series analysis of monthly routine data was used to estimate effects on 11 continuous quantity indicators. Effects were estimated separately for health centers and hospitals. Most quality indicators performed high at baseline, producing ceiling effects on further measurable improvements. Significant positive effects were observed for stocks of iron supplements (hospitals) and partographs (health centers). Four quantity indicators showed similar positive trend improvements across facility types (first-trimester antenatal visits, voluntary HIV-testing of couples, iron supplementation in pregnancy, vitamin A supplementation of children); two showed no change for either type of facility (skilled birth attendance, fully immunized one-year-olds); five indicators revealed different effect patterns for health centers and hospitals. In both health centers and hospitals, the largely positive PBI effects on antenatal care included resilience against interrupted supply chains and improvements in attendance rates. Observed heterogeneity might have been influenced by the availability of specific resources or the redistribution of service use.

RESUMO

There is an extensive body of research about chronic pain and treatment in developed countries. In contrast there is a lack of research on this topic in developing countries including China. This study was aimed to estimate the prevalence of chronic pain in different regions of China. Data on pain and its treatment were collected from 9357 participants using questionnaires and telephone-based interviews, from 31 regions of China. Gathered data were then coded into electronic data acquisition system and descriptive and inferential statistical analysis was performed. Out of 9298 participants, the ratio of chronic pain was 31.54% with the proportion of male having chronic pain (33.86%) was higher than that of female (29.53%). The average age of participants with pain (45.02 ± 15.07 years) was higher than free-pain participants (36.19 ± 11.12 years). There were also significant differences between groups in occupation, education levels, and illness history. Proportion of patients with pain duration of 1 year was 12.104%, between 1 and 5 years was 60%, and over 10 years was 10.74%. There were 63.9% of patients with moderate pain and 36.1% with severe pain. About 43.042% of patients thought that pain resulted in sleep disorder, 38.99% thought that it causes anxiety, and about 33% thought depression and irritable bowel was the result of their pain. For the chronic pain, more than half of patients used naprapathy, cupping, and other physical therapies. Up to 2016, the ratio of pain incidence was over 30% in China. The location of pain was focused on back and upper limb. There has been a lack of proper treatment. Patients with pain had obvious economic burden, and their quality of life and psychology were significantly affected.

RESUMO

Micronutrient deficiencies continue to be widespread among children under-five in low- and middle-income countries (LMICs), despite the fact that several effective strategies now exist to prevent them. This kind of malnutrition can have several immediate and long-term consequences, including stunted growth, a higher risk of acquiring infections, and poor development outcomes, all of which may lead to a child not achieving his or her full potential. This review systematically synthesizes the available evidence on the strategies used to prevent micronutrient malnutrition among children under-five in LMICs, including single and multiple micronutrient (MMN) supplementation, lipid-based nutrient supplementation (LNS), targeted and large-scale fortification, and point-of-use-fortification with micronutrient powders (MNPs). We searched relevant databases and grey literature, retrieving 35,924 papers. After application of eligibility criteria, we included 197 unique studies. Of note, we examined the efficacy and effectiveness of interventions. We found that certain outcomes, such as anemia, responded to several intervention types. The risk of anemia was reduced with iron alone, iron-folic acid, MMN supplementation, MNPs, targeted fortification, and large-scale fortification. Stunting and underweight, however, were improved only among children who were provided with LNS, though MMN supplementation also slightly increased length-for-age z-scores. Vitamin A supplementation likely reduced all-cause mortality, while zinc supplementation decreased the incidence of diarrhea. Importantly, many effects of LNS and MNPs held when pooling data from effectiveness studies. Taken together, this evidence further supports the importance of these strategies for reducing the burden of micronutrient malnutrition in children. Population and context should be considered when selecting one or more appropriate interventions for programming.

RESUMO

The World health Organization estimates that about 8 million babies die prematurely worldwide. Most of these cases are found in low-income countries (LICs). The use of neonatal incubators has proven to be very useful in the reduction of infant mortality. However, access to this important medical device is not always easy in LICs. This article presents the implementation of a multi-function neonatal incubator with remote monitoring, fingerprint scanner, phototherapy, and heart rate monitoring. In this view, proportional integral (PI) control algorithm and an Android application were developed. Furthermore, an initial social impact of the implemented neonatal incubator usage was performed in some hospitals in Cameroon.

RESUMO

BACKGROUND: Hypertension (HTN) and diabetes mellitus (DM) are highly prevalent in low- and middle-income countries (LMIC) and a leading cause of morbidity and mortality. Recent evidence on effectiveness of primary care interventions has attracted renewed calls for their implementation. This review aims to synthesize evidence pertaining to primary care interventions on these two diseases, evaluated and tested in LMICs. METHODS: Two reviewers conducted an electronic search of three databases (Pubmed, EMBASE and Web of Science) and screened for eligible articles. Interventions covering health promotion, prevention, treatment, or rehabilitation activities at the PHC or community level were included. Studies published in English, French, Portuguese and Spanish, from January 2007 to January 2017, were included. Key extraction variables included the 12 criteria identified by the Template for Intervention Description and Replication (TIDieR) checklist and guide. The Innovative Care for Chronic Conditions Framework (ICCCF) was used to guide analysis and reporting of results. RESULTS: 198 articles were analyzed. The strategies focused on healthcare service organization (76.5%), community level (9.7 %), creating a positive policy environment (3.6%) and strategies covering multiple domains (10.2%). Studies included related to the following topics: description or testing of interventions (n=81; 41.3%), implementation or evaluation projects (n=42; 21.4%), quality improvement initiatives (n=15; 7.7%), screening and prevention efforts (n=26; 13.2%), management of HTN or DM (n=13; 6.6%), integrated health services (n=10; 5.1%), knowledge and attitude surveys (n=5; 2.5%), cost-effective lab tests (n=2; 1%) and policy making efforts (n=2; 1%). Most studies reported interventions by non-specialists (n=86; 43.4%) and multidisciplinary teams (n=49; 25.5%). CONCLUSION: Only 198 articles were found over a 10 year period which demonstrates the limited published research on highly prevalent diseases in LMIC. This review shows the variety and complexity of approaches that have been tested to address HTN and DM in LMICs and highlights the elements of interventions needed to be addressed in order to strengthen delivery of care. Most studies reported little information regarding implementation processes to allow replication. Given the need for multi-component complex interventions, study designs and evaluation techniques will need to be adapted by including process evaluations versus simply effectiveness or outcome evaluations.

RESUMO

BACKGROUND: In an ageing world facing an epidemic of chronic diseases, there is great interest in the burden of multimorbidity on individuals and caregivers, yet no studies have examined the longitudinal association between multimorbidity and care dependence in low and middle income countries. Mental and cognitive disorders are associated with dependence but little is known about their role in the pathway to dependence in the context of multimorbidity. This study aims to determine (1) the association of multimorbidity with the onset of care dependence in older adults, accounting for mortality and controlling for sociodemographic factors, and (2) the independent effects of physical multimorbidity, mental and cognitive disorders. METHODS: A population-based cohort study of people aged 65 years and older in six countries in Latin America, and China. Data on chronic conditions and sociodemographic factors were collected at baseline. Multimorbidity was ascertained as a count of up to 15 mental, cognitive and physical health conditions. Dependence was ascertained through informant interviews at baseline and follow-up. We used competing risk regression to assess the association between multimorbidity and the onset of care dependence, acknowledging the possibility of dependence-free death. We also assessed the independent effects of physical multimorbidity and depression, anxiety and dementia individually. RESULTS: 12,965 participants, with no needs for care at baseline, were followed up for a median of 3.0-4.9 years. Each unit increase in multimorbidity count increased the cumulative risk of dependence by 20% in the fully adjusted model. Age was the only variable to confound this relationship. Physical multimorbidity was associated with only a modest increased risk of care dependence. Dementia, depression and anxiety were independently associated with incident care dependence at every level of physical multimorbidity, and depression and anxiety attenuated the effect of physical multimorbidity. CONCLUSION: Multimorbidity consistently predicts care dependence with little variation between countries. Physical multimorbidity imparts a lower risk than multimorbidity with mental and cognitive disorders included. Mental and cognitive disorders independently increase the risk of care dependence. Comprehensive and holistic assessment of disorders of body, brain and mind can help to identify older people at high risk of care dependence.

RESUMO

Diabetes mellitus is rapidly becoming one of the major diseases affecting people's health globally. Over half of 100 million diabetes patients who need insulin to survive, especially in low- and middle-income countries (LMIC), are not able to get this medicine and die prematurely. Since 2000, insulin-producing companies have started support programmes with a component of insulin donations to children and youth with type 1 diabetes in 43 LMIC. Based on their experiences we conclude, contrary to common belief, that the diagnosis, treatment, and prevention of fatal complications in children with type 1 diabetes in LMIC are very possible in practice, with large improvements in survival, mean body weight, mean glucose levels, and frequency of complications. Medicine donations can never offer a sustainable solution and we now propose a ten-step transition process towards a fully sustainable national diabetes care and prevention programme for children and youth with diabetes type 1.

RESUMO

Optimal care for children and adolescents with type 1 diabetes is well described in guidelines, such as those of the International Society for Pediatric and Adolescent Diabetes. High-income countries can usually provide this, but the cost of this care is generally prohibitive for lower-income countries. Indeed, in most of these countries, very little care is provided by government health systems, resulting in high mortality, and high complications rates in those who do survive. As lower-income countries work toward establishing guidelines-based care, it is helpful to describe the levels of care that are potentially affordable, cost-effective, and result in substantially improved clinical outcomes. We have developed a levels of care concept with three tiers: "minimal care," "intermediate care," and "comprehensive (guidelines-based) care." Each tier contains levels, which describe insulin and blood glucose monitoring regimens, requirements for hemoglobin A1c (HbA1c) testing, complications screening, diabetes education, and multidisciplinary care. The literature provides various examples at each tier, including from countries where the life for a child and the changing diabetes in children programs have assisted local diabetes centres to introduce intermediate care. Intra-clinic mean HbA1c levels range from 12.0% to 14.0% (108-130 mmol/mol) for the most basic level of minimal care, 8.0% to 9.5% (64-80 mmol/mol) for intermediate care, and 6.9% to 8.5% (52-69 mmol/mol) for comprehensive care. Countries with sufficient resources should provide comprehensive care, working to ensure that it is accessible by all in need, and that resulting HbA1c levels correspond with international recommendations. All other countries should provide Intermediate care, while working toward the provision of comprehensive care.

RESUMO

Defined as the co-occurrence of more than two chronic conditions, multi-morbidity has been described as a significant health care problem: a trend linked to a rise in non-communicable disease and an ageing population. Evidence on the experiences of living with multi-morbidity in middle-income countries (MICs) is limited. In high-income countries (HICs), multi-morbidity has a complex impact on health outcomes, including functional status, disability and quality of life, complexity of health care and burden of treatment. Previous evidence also shows that multi-morbidity is consistently higher amongst women. This study aimed to explore the perceptions and experiences of women living with multi-morbidity in the Greater Accra Region, Ghana: to understand the complexity of their health needs due to multi-morbidity, and to document how the health system has responded. Guided by the Cumulative Complexity Model, and using stratified purposive sampling, 20 in-depth interviews were conducted between May and September 2015 across three polyclinics in the Greater Accra Region. The data were analysed using the six phases of Thematic Analysis. Overall four themes emerged: 1) the influences on patients' health experience; 2) seeking care and the responsiveness of the health care system; 3) how patients manage health care demands; and 4) outcomes due to health. Spirituality and the stigmatization caused by specific conditions, such as HIV, impacted their overall health experience. Women depended on the care and treatment provided through the health care system despite inconsistent coverage and a lack of choice thereof, although their experiences varied by chronic condition. Women depended on their family and community to offset the financial burden of treatment costs, which was exacerbated by having many conditions. The implications are that integrated health and social support, such as streamlining procedures and professional training on managing complexity, would benefit and reduce the burden of multi-morbidity experienced by women with multi-morbidity in Ghana.
