RESUMO
BACKGROUND: Infection with resistant Pseudomonas aeruginosa (RPA) in the intensive care unit (ICU) is known to be either endogenous or exogenous or both, but the roles of each of these contamination routes are yet to be clarified. Data regarding prevalence, risk factors, and environmental factors associated with RPA in ICU are very scanty and even when they exist, they seem to be contradictory. So, there is a strong interest in understanding both individual and environmental factors associated with RPA infection. This systematic review aims to investigate individual and environmental factors associated with the colonization and infection with RPA in ICU. METHODOLOGY: MEDLINE (Pubmed), EMBASE (OVID), the Cochrane Library (Wiley), Web of Science, CINAHL (EBSCOHost), and LILACS (BIREME) will be searched from inception onwards. Grey literature will be identified through Google Scholar and Open Grey. Two reviewers will independently screen all citations, abstracts, and full-text articles. Potential conflicts will be resolved through discussion. Methodological quality including bias will be appraised using appropriate approaches. A narrative synthesis will describe the quality and content of the epidemiological evidence. Prevalence, odds ratio, relative risk, and hazard radio with their respective 95% confidence intervals will be calculated. A meta-analysis of data extracted from eligible studies with similar populations and RPA testing will be performed. The analysis will evaluate factors influencing the estimates. A random effect model will be used to summarize effect sizes. DISCUSSION: Two contrasting hypotheses on risk factors of acquisition, colonization, and infection of RPA are being debated, especially in a context where available data are scanty or exhibit high discrepancy. Indeed, most of the reviews have been focalized on hospitalized patients, and not in ICU, and few of them address the issue of environmental factors. To fill that gap, this review will combine both analyses of individual and environmental risk factors using prevalence studies in ICU and evaluation of different methodologies. These two hypotheses will be tested and challenged and could serve as a basis for a more in-depth study to fill the methodological gaps that will be identified as part of this current review. SYSTEMATIC REVIEW REGISTRATION: This protocol has been submitted to the Prospective Register of Systematic Reviews (PROSPERO) and the registration number attributed was CRD42021233832 of 07 March 2021.

INTRODUCTION: Postpartum family planning is still little known and little practised by most couples in Cameroon. However, just after childbirth, many couples wish to postpone their second birth. This study aims to determine the level of competence and the education need of couples in immediate postpartum family planning in the Biyem-Assi health district, Cameroon. METHODS: We performed a KAP survey (knowledge, attitudes and practices) in the Biyem-Assi health district. Data were collected using two questionnaires with 40 questions, written in french, one addressed to women in couples and during the post-partum period and the other addressed to men in couples and having at least one child. Collected data were entered in the software CSPro version 6.2 and then analyzed using the software SPSS version 20.0. RESULTS: A total of 300 subjects with a sex ratio of 1 were surveyed. More than half (56.7%) had an approximate knowledge of family planning in the immediate postpartum period. Thirty six percent of the respondents believed that the immediate postpartum period was not an appropriate time to use a modern method of contraception. The interaction between contraceptives and breast milk (65.4%) and female infertility (26.3%) were the main reasons reported. Immediate postpartum contraception of 60.5% of couples living in the Biyem-Assi health district was inadequate. Therefore, the level of competence in the immediate postpartum family planning was insufficient (32.6%) and low (23.3%) in most of the respondents. CONCLUSION: Some prejudices and misconceptions about modern contraceptive methods persist in the Biyem-Assi health district population and these are an obstacle to contraceptive practice in general and during the immediate postpartum period in particular. Awareness and education efforts of couples to improve their competence in contraception during the immediate postpartum period are necessary.

Achieving universal access to immunization, as envisioned in the global vaccine action plan continues to be a challenge for many countries in Sub-Saharan Africa. Weak immunization supply chain (iSC) has widely been recognized as a key barrier, hindering progress towards vaccination targets in this region. These iSCs, which were designed in the 1980s, have become increasing fragile and are now considered outdated. The objective of this review was to assess the effectiveness of system redesign and outsourcing to improve outdated iSC systems in sub-Saharan Africa. We searched the following electronic databases from January 2007 to December 2017: Medline, EMBASE (Excerpta Medica Database), the Cochrane Library, Google Scholar, CINAHL (Cumulative Index to Nursing and Allied Health Literature), WHOLIS (World Health Organization Library Database), LILACS (Latin American and Caribbean Literature on Health Sciences) and contacted experts in the field. Our search strategy yielded 80 records and after assessment for eligibility, seven papers met the inclusion criteria. Five studies evaluated the experiences of system redesign in three countries (Nigeria, Benin and Mozambique), two assessed outsourcing vaccine logistics to the private sector in Nigeria and South Africa. According to these studies, system redesign improved vaccine availability at service delivery points and reduce the cost of distributing vaccines. Similarly, outsourcing vaccine logistics to the private sector reduced the cost of vaccines distribution and improve vaccine availability at service delivery points.

World Health Organization (WHO) estimated in 2013 that 49,000 deaths all over the world were caused by neonatal tetanus. Only as recently as the year 2000, neonatal tetanus was a public health problem in 59 countries, but since then it has been eliminated in 36 of the countries concerned. The objective of this piece of work, therefore, was to investigate which strategies intended to increase demand for vaccination are effective in increasing anti-tetanus vaccination coverage of women in Sub Saharan Africa. We searched the following electronic databases from January 1989 to July 2016: Medline, EMBASE (Excerpta Medica Database), The Cochrane Library, Google Scholar, CINAHL (Cumulative Index to Nursing and Allied Health Literature), WHOLIS (World Health Organization Library Database), LILACS (Latin American and Caribbean Literature on Health Sciences) and contacted experts in the field. There were no restrictions to language or publication status. All study designs that could provide the information we sought were eligible, provided the studies were conducted in sub-Saharan Africa. Critical appraisal of all identified citations was done independently by two authors to establish the possible relevance of the articles for inclusion in the review. Our search strategy yielded 191 records and after assessment for eligibility, 6 papers met the criteria for inclusion. In Ivory Coast, after reorganization, health workers said they were satisfied with the work environment and the care provided in 91% and 96% of cases, respectively. In Kenya, the main factors contributing to having sufficiently immunized part of the population against tetanus are lower birth order, higher household wealth index, women's employment, making joint health-related decisions with a partner, and higher number of antenatal care visits. Particularly in Ethiopia, compared with other member countries, the size of the unimmunized population, reporting quality, fragileness of the health system, resource limitation, and others deserve further concerted attention. In Nigeria, the prevalence of missed opportunities was 66%. The factors responsible for missed opportunities were; poor history taking, lack of knowledge of the current immunization schedule, dependence on physician referral for immunization and inefficient immunization records keeping system. In Nigeria, socio-logistic variables found to be important in Expanded Programme on Immunization implementations included scheduling, health staff attitude, intersectoral collaboration, and health education. Lack of community participation was also found to be a crucial constraining factor. There are many challenges to increase immunization coverage of tetanus vaccine for women. So far very few interventions addressing these challenges have been evaluated scientifically. Community mobilization interventions to change or impact beliefs and attitudes of women are absolutely needed. Additionally, improving accessibility, affordability, availability and accommodation of vaccination service venues will make them more attractive.

The African Program for Onchocerciasis Control (APOC) was launched in 1995 with the main goal being to boost the fight against onchocerciasis in Africa. In 2011, over 80 million people benefited from this intervention thanks to the contribution of 268.718 Community-Directed Distributors (CDD). These significant results obscure the role of women CDD in this fight. Indeed, the insufficient involvement of female CDD has been identified as a concern by the APOC partners early in the program. The present study aims to assess the contribution and performance of women involved in a strategy to control onchocerciasis by community-directed treatment with ivermectin in sub Saharan Africa. We searched the following electronic databases from January 1995 to July 2013: Medline, Embase (Excerpta Medica Database), CINAHL (Cumulative Index to Nursing and Allied Health Literature), LILAS (Latin American and Caribbean Literature on Health Sciences), International Bibliography of Social Sciences, Social Services Abstracts, and Sociological Abstracts. Two research team members independently conducted data extraction from the final sample of articles by using a pre-established data extraction sheet. The primary outcome was the contribution of female CDD in the control of onchocerciasis by community-directed treatment with Ivermectin. Of 25 hits, 7 papers met the inclusion criteria. For the management of onchocerciasis, female CDDs are elected by the health committee from the communities they will serve. The significant proportion of those treated (about 61%) were women, although only 24% of CDDs were women. Many community members reported that women were more committed, persuasive and more patient than men in the distribution of ivermectin. Some studies have identified underutilization of female CDD as one reason for the limited effectiveness or, in some cases, pure failure related to the distribution of Ivermectin interventions in the fight against onchocerciasis in sub-Saharan Africa. Evidence from this review suggests that female CDD contribute to the treatment of onchocerciasis with Ivermectin in sub-Saharan Africa. Large-scale rigorous studies including Randomized controlled trials (RCTs) are needed to compare Community-Directed intervention involving men and women CDDs.

INTRODUCTION: Intestinal parasites are more common in people with HIV, especially in tropical developing countries. This cross-sectional study was carried out to assess the prevalence of intestinal parasites among people with HIV at the Yaoundé Central Hospital Accredited Treatment Centre. METHODS: Structured questionnaires were used to collect clinical information after obtaining consent from the participants. Stool samples were collected from 207 HIV-positive patients for the investigation of intestinal pathogens using direct microscopy, formalin-ether concentration, ZiehlNeelsen modified and Kato-Katz methods. Data was analyzed using Epi-info version 3.4.1. and Microsoft Office Excel 2007. RESULTS: A total of 207 people were recruited. Eighty (38.65%) were male and 127 (61.35%) were female. The overall prevalence of intestinal parasite infections was 57.48% (119/207). The parasites detected in our study population included Entamoeba coli (22.68%), Ascaris lumbricoïdes (22.68%), Entamoeba histolytica(15.93%), Cryptosporidium spp (12.60%), Isospora belli (10.08%), Trichuris trichiura (7.60%), Strongyloïdesstercoralis (5.88%), Ancylostomaduodenale and Necatoramericanus (2.52%). CONCLUSION: At the end of our study, it appears that intestinal parasites still occupy an important place among HIV-positive patients.

The World Health Organization (WHO) estimated in 2012 that 287,000 maternal deaths occurred in 2010; sub-Saharan Africa (56%) and Southern Asia (29%) accounted for the global burden of maternal deaths. Men are also recognized to be responsible for the large proportion of ill reproductive health suffered by their female partners. Male involvement helps not only in accepting a contraceptive but also in its effective use and continuation. The objectives were to assess men's knowledge, attitude, and practice of modern contraceptive methods; determine the level of spousal communication about family planning decision making; and investigate the correlates of men's opinion about their roles in family planning decision making. We searched the following electronic databases from January 1995 to December 2013: Medline, Embase, CINAHL, LILAS, International Bibliography of Social Sciences, Social Services Abstracts, and Sociological Abstracts. Along with MeSH terms and relevant keywords, we used the Cochrane Highly Sensitive Search Strategy for identifying reports of articles in PubMed. There were no restrictions to language or publication status. Of 137 hits, 7 papers met the inclusion criteria. The concept of family planning was well known to men. In the Nigerian study, almost (99%) men were aware of the existence of modern contraceptives, and most of them were aware of at least two modern methods. Awareness of the condom was highest (98%). In the Malawi study, all of the participants reported that they were not using contraception before the intervention. In Ethiopia, above 90% of male respondents have supported and approved using and choosing family planning methods, but none of them practiced terminal methods. Generally, more male respondents disagreed than agreed that men should make decisions about selected family planning issues in the family. Decision-making dynamics around method choice followed a slightly different pattern. According to female participants, decisions regarding method choice were equally made by women or jointly, with male-dominated decisions falling last. There are many challenges to increase male involvement in family planning services. So far very few interventions addressing these challenges have been evaluated scientifically. Health education campaigns to improve beliefs and attitudes of men are absolutely needed. Additionally, improving accessibility, affordability, availability, accommodation and acceptability of family planning service venues will make them more attractive for male partners.

Buruli ulcer (BU) is a cutaneous neglected tropical disease caused by Mycobacterium ulcerans. Synthesizing the evidence on their efficacy of antibiotic in the management of BU can help to better define their roles, identify weaknesses and inform clinicians on relevant measures than can be used to control BU. Our objectives is to assess the clinical efficacy of Rifampicin-Streptomycin given for 8 weeks of treatment of early M. ulcerans infection. We searched the following electronic databases from January 2005 to July 2012: Medline, EMBASE (Excerpta Medica Database), The Cochrane Library, Google Scholar, CINAHL (Cumulative Index to Nursing and Allied Health Literature), WHOLIS (World Health Organization Library Database), LILACS (Latin American and Caribbean Literature on Health Sciences) and contacted experts in the field. There were no restrictions to language or publication status. All study designs that could provide the information we sought for were eligible provided the studies were conducted in the third world. Critical appraisal of all identified citations was done independently by three authors to establish the possible relevance of the articles for inclusion in the review. Of the 115 studies, 09 papers met the inclusion criteria. The duration of treatment ranged from 8 to 48 weeks depending on the severity. Oral chemotherapy alone obtained a curative rate of 50%. The "dual" mode of treatment (surgery + chemotherapy) reduced hospital admission period from 90 to 39.8 days, that's to 44.2%. This treatment for early stages could therefore replace surgery and in severe cases, is an indispensable aid before surgery. These results confirmed that the daily administration of Rifampicin and Streptomycin is an effective treatment for M. ulcerans infection in an early stage. Subsequent systematic reviews should be conducted to determine if antibiotics could heal injuries without resorting to surgery and to compare different treatment durations.

UNLABELLED: Buruli ulcer (BU) is a cutaneous neglected tropical disease caused by Mycobacterium ulcerans. Participation of Community Health Workers (CHWs) is an integral part of the management of BU, yet their impact has not been systematically evaluated in sub-Saharan Africa. METHODS: Our objectives were to summarize the evidence on the impact of CHWs on the control of BU in sub-Saharan Africa by looking at their recruitment, training, non-governmental support and performance. We searched the following electronic databases from January 1998 to July 2012: Medline, EMBASE (Excerpta Medica Database), The Cochrane Library, Google Scholar, CINAHL (Cumulative Index to Nursing and Allied Health Literature), WHOLIS (World Health Organization Library Database), LILACS (Latin American and Caribbean Literature on Health Sciences) and contacted experts in the field. There were no restrictions to language or publication status. All study designs that could provide the information we sought were eligible, provided the studies were conducted in sub-Saharan Africa. Critical appraisal of all identified citations was done independently by two authors to establish the possible relevance of the articles for inclusion in the review. Of 195 hits, 17 papers met the inclusion criteria. For the management of Buruli Ulcer, CHWs are often recruited from the communities they will serve. Communities play a role in CHW selection. Larger numbers of CHWs are needed in order to improve the detection and management of cases. One of the major obstacles to the control of BU is inadequate and poorly- equipped health facilities in the affected areas. Evidence from this review suggests that CHW programmes can have large impacts on the control of BU in sub-Saharan Africa. Large-scale rigorous studies, including RCTs, are needed to assess whether the CHWs programs promote equity and access.

INTRODUCTION: Buruli ulcer (BU) is a skin disease caused by Mycobacterium ulcerans. It is the third most common mycobacterial infection after tuberculosis and leprosy. Community Health Workers (CHWs) hold the potential to support patients and their families at the community level. METHODS: We conducted a cross-sectional descriptive study to assess the participation of CHWs in the early diagnosis and treatment of BU in Ngoantet, Cameroon. The CHWs performance was measured using: the number of cases referred to the Ngoantet Health Centre, the percentage of accomplished referrals, the percentage of cases referred by CHWs confirmed by the staff of Ngoantet Health Centre. Data was analyzed using Epi-info version 3.4.1. and Microsoft Office Excel 2003. The study focused on 51 CHWs in the Ngoantet health area. RESULTS: The referral rate was 95.0%. Most of the suspicious cases (91.5%) referred were confirmed by health workers. Most CHWs (78.4%) declared that they had identified at least one presumptive case of BU infection. CONCLUSION: We conclude that the CHWs can play a key role in scaling up BU control activities using a referral system. This study confirms the role of home visits and inspections in the early detection and treatment of BU.
