Women’s well-being and functioning after evidence-based antenatal care: a protocol for a systematic review of intervention studies
Authors: Andreucci Carla Betina , Filippi Veronique , Cecatti Jose Guilherme 
Published: February 2021

IntroductionThe 2016 WHO antenatal guidelines propose evidence-based recommendations to improve maternal outcomes. We aim to complement these recommendations by describing and estimating the effects of the interventions recommended by WHO on maternal well-being or functioning.Methods and analysisWe will conduct a systematic review of experimental and quasi-experimental studies evaluating women’s well-being or functioning following the implementation of evidence-based antenatal interventions, published in peer-reviewed journals through a 15-year interval (2005–2020). The lead reviewer will screen all records identified at MEDLINE, EMBASE, CINAHL Plus, LILACS and SciELO. Two other reviewers will control screening strategy quality. Quality and risk of bias will be assessed using a specially designed instrument. Data synthesis will consider the instruments applied, how often they were used, conditions/interventions for positive or negative effects documented, statistical measures used to document effectiveness and how results were presented. A random-effects meta-analysis comparing frequently used instruments may be conducted.Ethics and disseminationThe study will be a systematic review with no human beings’ involvement, therefore not requiring ethical approval. Findings will be disseminated through peer-reviewed publication and scientific events.PROSPERO registration numberCRD42019143436.

Published: February 2021

ObjectivesThe study was focused on geographical mapping of dengue cases and also to identify the hotspots or high-risk areas of dengue in Delhi.DesignA retrospective spatial–temporal (ecological) study. Descriptive analysis was used to know the distribution of dengue cases by age, sex, seasons and districts of Delhi. The spatiotemporal analysis was performed using inverse distance weighting and Getis-Ord Gi* statistic to know the geographical distribution and identify the hotspot areas.SettingsAll the confirmed and diagnosed dengue cases (IgM +ve or NS1 Antigen +ve ELISA) recorded by the Municipal Corporation of Delhi for the last 4 years (2015–2018) were collected with their local address. The location of all the dengue cases was geocoded using their address to prepare the spatiotemporal dengue database.ParticipantsRecord of all the dengue cases (4179) reported for treatment in the hospitals during the past 4 years were extracted and included in the study. Data were not collected directly from dengue patients.ResultsSeasonal occurrence of dengue cases (4179) shows that the cases start emerging in July, peaked in September–October and declined in December. The proportions of dengue cases were recorded high among the males 57.3% compared with females 42.6%, and differences were also recorded in all the age groups with more cases in age groups <15 and 16-30 years. Mapping of the cases reflects the spatial heterogeneity in the geographical distribution. The geomapping of cases indicates the presence of a significantly high number of cases in West, Southwest, South and Southeast districts of Delhi. High-risk areas or hotspots were also identified in this region.ConclusionDengue occurrence shows significant association with age, sex and seasons. The spatial analysis identified the high-risk areas, which can aid health administrators to take necessary action for prevention and better disease management.

ObjectiveThere is a decline in contraceptive use among sexually active unmarried young women in Ghana. This study assessed the prevalence of contraceptive knowledge and use, and the determinant of contraceptive use among sexually active unmarried young women in Ghana.DesignThis was a nationally representative cross-sectional survey, using data from the 2017 Ghana Maternal Health Survey. Weighted logistic regression was used to assess the association between background and obstetric characteristics of young women and contraceptive use.SettingGhana.ParticipantsA total of 809 sexually active unmarried adolescent girls (15–19 years) and young women (20–24 years).Primary and secondary outcome measuresKnowledge and use of both modern and traditional contraceptive methods.ResultsKnowledge of at least one modern and traditional contractive method was 99.8% and 95.0%, respectively. The prevalence of contraceptive use was 43%—with 34% modern and 9% traditional methods. From the unadjusted analyses, age (p=0.002), past pregnancy (p<0.001), abortion in the past 5 years (p=0.007) and history of childbirth (p=0.025) were independently associated with contraceptive use, whereas education (p=0.072), place of residence (p=0.702), household wealth (p=0.836) and age at first sex (p=0.924) were not independently associated with contraceptive use. In the adjusted analysis, contraceptive use was significantly higher among respondents with secondary education compared with those with primary education (OR 2.43, 95% CI 1.31 to 4.49, p=0.017), and was higher among respondents with a history of pregnancy (OR 2.13, 95% CI 1.48 to 3.06, p<0.001).ConclusionThere is a significant gap between knowledge and use of contraceptives among the study population. While intensifying knowledge of adolescents and young women on contraceptives, adolescent-friendly corners should be established at vantage points to increase utilisation and to prevent societal stigma on young women who access contraceptives services.

Published: February 2021

IntroductionAlthough the impact of macrolevel characteristics of health systems on socioeconomic inequity in health has been studied extensively, the impact of access characteristics on a smaller scale of health systems has received less attention. These mesolevel characteristics can influence access to healthcare and might have the potential to moderate or aggravate socioeconomic inequity in healthcare use. This scoping review aims to map the existing evidence of the association of socioeconomic inequity in healthcare use and mesolevel access characteristics of the health system.Methods and analysisIn conducting the scoping review, we follow the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols Extension for Scoping Reviews. The search will be carried out in four scientific databases: MEDLINE (via PubMed), Web of Science, Scopus and PsycINFO. Main eligibility criteria are inclusion in the analysis of a measure of socioeconomic position, a measure of individual healthcare use and a mesolevel determinant of access to healthcare services. The selection process consists of two consecutive screening stages (first: title/abstract; second: full text). At both stages, two reviewers independently assess the eligibility of studies. In case of disagreement, a third reviewer will be involved. Cohen’s kappa will be calculated to report inter-rater agreement between reviewers. Results are synthesised narratively, as a high heterogeneity of studies is expected.Ethics and disseminationNo primary data are collected for the presented scoping review. Therefore, ethical approval is not necessary. The scoping review will be published in an international peer-reviewed journal, and findings will be presented on national and international conferences.

Published: February 2021

IntroductionCannabis use in Canada is becoming more prevalent across all demographic groups due to increases in accessibility and lowered perceptions of harm. These patterns are mirrored among women of reproductive age, including women who are pregnant. Given increasing evidence for detrimental short- and long-term impacts of cannabis exposure on fetal, newborn and child outcomes, there is a need for high-quality, accessible resources providing reliable guidance and recommendations on this topic for both the public and healthcare providers. We will conduct a scoping review to identify and characterise all publicly available online educational resources discussing cannabis use related to fertility, pregnancy and breastfeeding developed by Canadian organisations.Methods and analysisUsing Arksey and O’Malley’s scoping review methodology as a guide, we will search Medline (Ovid), Medline in Process (Ovid), Embase (Ovid), ERIC (Ovid), CINAHL (EBSCOhost) and Education Source (EBSCOhost). We will also conduct a grey literature search targeting the websites of national and independent Canadian obstetrical societies and networks, and government and public health offices that provide recommendations or guidance to individuals and their healthcare providers seeking information on cannabis use related to fertility, pregnancy or breastfeeding.Ethics and disseminationResearch ethics approval is not required for scoping review studies. We anticipate that this review’s findings will be disseminated through traditional channels, including preprint and peer-reviewed publications and presentations at academic conferences. In addition, the resources and guidelines identified in the study will be gathered and made available online on a single comprehensive public repository.Protocol registration numberosf.io/p24y5.

ObjectiveThe increasing incidence of sports injury among athletes calls for systemic surveillance of injuries and illnesses in this field to develop preventive measures. The patterns of injuries and illnesses that occurred among Korean athletes during the 2018 Asian Games held in Indonesia were studied.MethodsWe recorded the occurrence of all injuries and illnesses reported to the chief medical officer, coordinated with the help of an instant social messaging application in real time.ResultsA total of 782 elite athletes participated in 46 sporting events. A total of 141 (18.03%) injuries were recorded, with 121 (15.47%) athletes suffering at least one injury. Out of 141 injuries 80 (56.74%) were in male athletes and 61 (43.26%) were in female athletes. The highest number of injuries was seen among sport climbing athletes (n=10, 71.43%), followed by sepak takraw. A total of 16 (11.35%) injuries were expected to prevent athletes from participation in competition/training. Most of the injuries occurred during training (46.10%), with lower lumbar spine being the most common part injured. A total of 209 (26.72%) illnesses were reported, with at least one illness in 170 (21.73%) athletes. The incidence among female athletes (26.90%) was comparable with that of male athletes (26.90%). Maximum illness rate was reported in table tennis (100%). The most common system involved was gastrointestinal (n=93, 44.49%), followed by respiratory (n=53, 25.36%). Environmental factors were causative in 111 athletes (53.11%) and infection in 79 (37.79%). Illnesses resulted in loss of at least 1 day among 30 (14.35%) athletes.ConclusionOverall 15.47% of athletes suffered at least one injury and 21.73% suffered at least one illness; the incidence of injury and illness varied depending on the type of sports.

AimsAccurate and reliable diagnosis is essential for lung cancer treatment. The study aim was to investigate interpathologist diagnostic concordance for pulmonary tumours according to WHO diagnostic criteria.MethodsFifty-two unselected lung and bronchial biopsies were diagnosed by a thoracic pathologist based on a broad spectrum of immunohistochemical (IHC) stainings, molecular data and clinical/radiological information. Slides stained with H&E, thyroid transcription factor-1 (TTF-1) clone SPT24 and p40 were scanned and provided digitally to 20 pathologists unaware of reference diagnoses. The pathologists independently diagnosed the cases and stated if further diagnostic markers were deemed necessary.ResultsIn 31 (60%) of the cases, ≥80% of the pathologists agreed with each other and with the reference diagnosis. Lower agreement was seen in non-small cell neuroendocrine tumours and in squamous cell carcinoma with diffuse TTF-1 positivity. Agreement with the reference diagnosis ranged from 26 to 45 (50%–87%) for the individual pathologists. The pathologists requested additional IHC staining in 15–44 (29%–85%) of the 52 cases. In nearly half (17 of 36) of the malignant cases, one or more pathologist advocated for a different final diagnosis than the reference without need of additional IHC markers, potentially leading to different clinical treatment.ConclusionsInterpathologist diagnostic agreement is moderate for small unselected bronchial and lung biopsies based on a minimal panel of markers. Neuroendocrine morphology is sometimes missed and TTF-1 clone SPT24 should be interpreted with caution. Our results suggest an intensified education need for thoracic pathologists and a more generous use of diagnostic IHC markers.

BackgroundFabry disease is a rare X-linked lysosomal storage disease caused by mutations in the galactosidase α gene. Deficient activity of α-galactosidase A leads to glycosphingolipid accumulations in multiple organs. Circular RNAs represent strong regulators of gene expression. Their circular structure ensures high stability in blood. We hypothesised that blood-based circular RNA profiles improve phenotypic assignment and therapeutic monitoring of Fabry disease.MethodsA genome-wide circular RNA expression analysis was performed in blood of genetically diagnosed patients with Fabry disease (n=58), age-matched and sex-matched healthy volunteers (n=14) and disease control patients with acute kidney injury (n=109). Most highly dysregulated circular RNAs were validated by quantitative real-time PCR. Circular RNA biomarker sensitivity, specificity, predictive values and area under the curve (AUC) were determined. Linear regression analyses were conducted for validated circular RNA biomarkers and clinical patient characteristics.ResultsA distinct circular RNA transcriptome signature identified patients with Fabry disease. Level of circular RNAs hsa_circ_0006853 (AUC=0.73), hsa_circ_0083766 (AUC=0.8) and hsa_circ_0002397 (AUC=0.8) distinguished patients with Fabry disease from both healthy controls and patients with acute kidney injury. Hsa_circ_0002397 was, furthermore, female-specifically expressed. Circular RNA level were significantly related to galactosidase α gene mutations, early symptoms, phenotypes, disease severities, specific therapies and long-term complications of Fabry disease.ConclusionThe discovery of circular RNA-based and Fabry disease–specific biomarkers may advance future diagnosis of Fabry disease and help to distinguish related phenotypes.

ObjectiveSLE is a strong risk factor for premature cardiovascular (CV) disease and mortality. We investigated which factors could explain poor prognosis in SLE compared with controls.MethodsPatients with SLE and population controls without history of clinical CV events who performed carotid ultrasound examination were recruited for this study. The outcome was incident CV event and death. Event-free survival rates were compared using Kaplan-Meier curves. Relative HR (95% CI) was used to estimate risk of outcome.ResultsPatients (n=99, 87% female), aged 47 (13) years and with a disease duration of 12 (9) years, had mild disease at inclusion, Systemic Lupus Erythematosus Diseases Activity Index score of 3 (1–6) and Systemic Lupus International Collaborating Clinics (SLICC) Damage Index score of 0 (0–1). The controls (n=109, 91% female) were 49 (12) years old. Baseline carotid intima-media thickness (cIMT) did not differ between the groups, but plaques were more prevalent in patients (p=0.068). During 10.1 (9.8-10.2) years, 12 patients and 4 controls reached the outcome (p=0.022). Compared with the controls, the risk of the adverse outcome in patients increased threefold to fourfold taking into account age, gender, history of smoking and diabetes, family history of CV, baseline body mass index, waist circumference, C reactive protein, total cholesterol, high-density lipoprotein, low-density lipoprotein, dyslipidaemia, cIMT and presence of carotid plaque. In patients, higher SLICC score and SLE-antiphospholipid syndrome (SLE-APS) were associated with increased risk of the adverse outcome, with respective HRs of 1.66 (95% CI 1.20 to 2.28) and 9.08 (95% CI 2.71 to 30.5), as was cIMT with an HR of 1.006 (95% CI 1.002 to 1.01). The combination of SLICC and SLE-APS with cIMT significantly improved prediction of the adverse outcome (p<0.001).ConclusionIn patients with mild SLE of more than 10 years duration, there is a threefold to fourfold increased risk of CV events and death compared with persons who do not have SLE with similar pattern of traditional CV risk factors, cIMT and presence of carotid plaque. SLICC, SLE-APS and subclinical atherosclerosis may indicate a group at risk of worse outcome in SLE.

ObjectiveAlthough there are regional reports that the COVID-19 pandemic is associated with a reduction in acute myocardial infarction presentations and primary percutaneous coronary intervention (PCI) procedures, little is known about the impact of the COVID-19 pandemic on mechanical complications resulting from ST-segment elevation myocardial infarction (STEMI) and mortality.MethodsThis single-centre retrospective cohort study analysed presentations, incidence of mechanical complications, and mortality in patients with STEMI before and after a state of emergency was declared due to the COVID-19 pandemic by the Japanese government on 7 April 2020.ResultsWe analysed 359 patients with STEMI hospitalised before the declaration and 63 patients hospitalised after the declaration. The proportion of patients with late presentation was significantly higher after the declaration than before (25.4% vs 14.2%, p=0.03). The incidence of late presentation was significantly higher during the COVID-19 pandemic than before (incidence rate ratio (IRR), 2.41; 95% CI, 1.37 to 4.05; p=0.001, even after adjusting for month (IRR, 2.61; 95% CI, 1.33 to 5.13; p<0.01). Primary PCI was performed significantly less often after the declaration than before (68.3% vs 82.5%, p=0.009). The mechanical complication resulting from STEMI occurred in 13 of 359 (3.6%) patients before the declaration and 9 of 63 (14.3%) patients after the declaration (p<0.001). However, the incidence of in-hospital death (before, 6.2% vs after, 6.4%, p=0.95) was comparable.ConclusionsFollowing the COVID-19 pandemic, an increased incidence of mechanical complications resulting from STEMI was observed. Instructing people to stay at home, without effectively educating them to immediately seek medical attention when suffering symptoms of a heart attack, may worsen outcomes in patients with STEMI.

ObjectivesTo investigate if inflammation detected by MRI or ultrasound at rheumatoid arthritis (RA) onset is predictive of erosive progression or poor response to methotrexate monotherapy, and to investigate if subclinical inflammation in remission is predictive of future treatment escalation or erosive progression.MethodsIn a 2-year study, 218 patients with disease-modifying antirheumatic drug-naïve early RA were treated by a tight-control treat-to-target strategy corresponding to current recommendations. MRI and ultrasound were performed at regular intervals. Baseline imaging-based inflammation measures were analysed as predictors for early methotrexate failure and erosive progression using univariate and multivariate regression adjusted for clinical, laboratory and radiographic measures. In patients in remission after 1 year, imaging measures were analysed as predictors of treatment escalation and erosive progression during the second year. The added value of imaging in prediction models was assessed using receiver operating characteristic analyses.ResultsBaseline MRI inflammation was associated with MRI erosive progression and ultrasound with radiographic erosive progression. No imaging inflammation measure was associated with early methotrexate failure. Imaging inflammation was present in a majority of patients in clinical remission. Tenosynovitis was associated with treatment escalation, and synovitis and tenosynovitis with MRI/radiographic erosive progression during the second year. Imaging information did not improve prediction models for any of the outcomes.ConclusionsImaging-detected inflammation, both at diagnosis and in remission, is associated with elements of future disease development. However, the lack of a significant effect on prediction models indicates limited value of systematic MRI and ultrasound in management of early RA.
