Meta-Analysis Review
OBJECTIVE
Hypertensive disorders of pregnancy are associated with a long-term risk for cardiovascular disease among parous patients later in life. However, relatively little is known about whether hypertensive disorders of pregnancy are associated with an increased risk for ischemic stroke or hemorrhagic stroke in later life. This systematic review aimed to synthesize the available literature on the association between hypertensive disorders of pregnancy and the long-term risk for maternal stroke.
DATA SOURCES
PubMed, Web of Science, and CINAHL were searched from inception to December 19, 2022.
STUDY ELIGIBILITY CRITERIA
Studies were only included if the following criteria were met: case-control or cohort studies that were conducted with human participants, were available in English, and that measured the exposure of a history of hypertensive disorders of pregnancy (preeclampsia, gestational hypertension, chronic hypertension, or superimposed preeclampsia) and the outcome of maternal ischemic stroke or hemorrhagic stroke.
METHODS
Three reviewers extracted the data and appraised the study quality following the Meta-analyses of Observational Studies in Epidemiology guidelines and using the Newcastle-Ottawa scale for risk of bias assessment.
RESULTS
The primary outcome was any stroke (undifferentiated) and secondary outcomes included ischemic stroke and hemorrhagic stroke. The protocol for this systematic review was registered in the International Prospective Register of Systematic Reviews under identifier CRD42021254660. Of 24 studies included (10,632,808 study participants), 8 studies examined more than 1 outcome of interest. Hypertensive disorders of pregnancy were significantly associated with any stroke (adjusted risk ratio, 1.74; 95% confidence interval, 1.45-2.10). Preeclampsia was significantly associated with any stroke (adjusted risk ratio, 1.75; 95% confidence interval, 1.56-1.97), ischemic stroke (adjusted risk ratio, 1.74; 95% confidence interval, 1.46-2.06), and hemorrhagic stroke (adjusted risk ratio, 2.77; 95% confidence interval, 2.04-3.75). Gestational hypertension was significantly associated with any stroke (adjusted risk ratio, 1.23; 95% confidence interval, 1.20-1.26), ischemic stroke (adjusted risk ratio, 1.35; 95% confidence interval, 1.19-1.53), and hemorrhagic stroke (adjusted risk ratio, 2.66; 95% confidence interval, 1.02-6.98). Chronic hypertension was associated with ischemic stroke (adjusted risk ratio, 1.49; 95% confidence interval, 1.01-2.19).
CONCLUSION
In this meta-analysis, exposure to hypertensive disorders of pregnancy, including preeclampsia and gestational hypertension, seems to be associated with an increased risk for any stroke and ischemic stroke among parous patients in later life. Preventive interventions may be warranted for patients who experience hypertensive disorders of pregnancy to reduce their long-term risk for stroke.

Review
BACKGROUND
With rising time constraints, health care professionals increasingly depend on technology to provide health advice and teach patients how to manage chronic disease. The effectiveness of video-based tools in improving knowledge, health behaviors, disease severity, and health care use for patients with major chronic illnesses is not well understood.
OBJECTIVE
The aim of this study was to assess the current literature regarding the efficacy of video-based educational tools for patients in improving process and outcome measures across several chronic illnesses.
METHODS
A systematic review was conducted using CINAHL and PubMed with predefined search terms. The search included studies published through October 2021. The eligible studies were intervention studies of video-based self-management patient education for an adult patient population with the following chronic health conditions: asthma, chronic kidney disease, chronic obstructive pulmonary disease, chronic pain syndromes, diabetes, heart failure, HIV infection, hypertension, inflammatory bowel disease, and rheumatologic disorders. The eligible papers underwent full extraction of study characteristics, study design, sample demographics, and results. Bias was assessed with the Cochrane risk-of-bias tools. Summary statistics were synthesized in Stata SE (StataCorp LLC). Data reporting was conducted per the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) checklist.
RESULTS
Of the 112 studies fully extracted, 59 (52.7%) were deemed eligible for inclusion in this review. The majority of the included papers were superiority randomized controlled trials (RCTs; 39/59, 66%), with fewer pre-post studies (13/59, 22%) and noninferiority RCTs (7/59, 12%). The most represented conditions of interest were obstructive lung disease (18/59, 31%), diabetes (11/59, 19%), and heart failure (9/59, 15%). The plurality (28/59, 47%) of video-based interventions only occurred once and occurred alongside adjunct interventions that included printed materials, in-person counseling, and interactive modules. The most frequently studied outcomes were disease severity, health behavior, and patient knowledge. Video-based tools were the most effective in improving patient knowledge (30/40, 75%). Approximately half reported health behavior (21/38, 56%) and patient self-efficacy (12/23, 52%) outcomes were improved by video-based tools, and a minority of health care use (11/28, 39%) and disease severity (23/69, 33%) outcomes were improved by video-based tools. In total, 48% (22/46) of the superiority and noninferiority RCTs and 54% (7/13) of the pre-post trials had moderate or high risk of bias.
CONCLUSIONS
There is robust evidence that video-based tools can improve patient knowledge across several chronic illnesses. These tools less consistently improve disease severity and health care use outcomes. Additional study is needed to identify features that maximize the efficacy of video-based interventions for patients across the spectrum of digital competencies to ensure optimized and equitable patient education and outcomes.

Meta-Analysis
BACKGROUND
There is a dearth of robust evidence regarding the correlation between psoriasis with maternal and neonatal outcomes, making it challenging to establish definitive recommendations for the management of these patients. This systematic review and meta-analysis aimed to review the evidence with regard to the impact of maternal psoriasis on maternal and neonatal outcomes.
METHODS
Following the PRISMA guideline, a systematic search of English articles using PubMed, Embase, Scopus, ScienceDirect, Web of Science, Google Scholar, and the Cochrane Library was conducted. The search was performed from inception to 22 of May 2022.
RESULT
A significant association was observed between psoriasis and maternal outcomes, including cesarean delivery [OR = 1.25 (95% CI: 1.13-1.30, p-value = 0.001)], (pre)eclampsia [OR = 1.29 (95% CI: 1.15-1.44, p-value = 0.0001)], gestational diabetes [Odds Ratio (OR) = 1.23 (95% Confidence Intervals (CI): 1.15-1.30, p-value = 0.001)], gestational hypertension [OR = 1.31 (95% CI: 1.18-1.45, p-value = 0.001)] and preterm birth [OR = 1.22 (95% CI: 1.10-1.35, p-value = 0.001)]. Also, there was a significant association between psoriasis and neonatal outcomes, including small for gestational age [OR = 1.07 (95% CI: 1.02-1.11, p-value = 0.053)], low birth weight [OR = 1.19 (95% CI: 1.02-1.38, p-value = 0.001)] and stillbirth [OR = 1.27 (95% CI: 1.04-1.55, p-value = 0.023)].
CONCLUSION
Maternal psoriasis could negatively impact maternal and neonatal outcomes. Our results strengthen the importance of close monitoring of the mothers' psoriasis status before and during pregnancy.

Most pregnancy complications originate with early placentation. MicroRNAs (miRNAs) may play an important role in placentation and function as biomarkers of future pregnancy complications. We summarized from the literature all first trimester circulating miRNAs associated with pregnancy complications of placental origin and further identified the miRNAs which have the most evidence as potential early biomarkers for pregnancy complications. We conducted a systematic review following PRISMA reporting guidelines (PROSPERO CRD42020183421). We identified all first trimester serum or plasma miRNAs associated with a pregnancy complication of placental origin (preeclampsia, intrauterine growth restriction (IUGR), gestational hypertension, preterm delivery) and the number of times those miRNAs were identified, as a measure of replication. Twenty-one studies examined 118 unique miRNAs, and 87 were associated with at least one pregnancy complication; preeclampsia was the most common. Seven miRNAs were significantly associated with a pregnancy complication in at least two studies: miR-125b, miR-518b, miR-628-3p, miR-365a-3p, miR-520h, miR-374a-5p, miR-191-5p. Few miRNAs were associated with more than one pregnancy complication: miR-518b and miR-520h with preeclampsia and gestational hypertension, miR-374a-5p and miR-191-5p with preterm birth and preeclampsia. Our systematic review suggests seven miRNAs as potential biomarkers of pregnancy complications. These complications are thought to originate with early placental defects and these miRNAs may also be biomarkers of placental pathology. First-trimester biomarkers of pregnancy complications can facilitate early detection and interventions.

Review
Obesity is reported to have a protective effect on mortality in pulmonary hypertension (PH), a phenomenon known as obesity paradox. However, the data are conflicting, with some studies showing decreased mortality while other studies found no effect of obesity on mortality. Therefore, we performed a systematic review and meta-analysis to examine whether there is an association between obesity and mortality in PH. Only patients with PH diagnosed by right heart catheterization were included. We also performed a sub-group analysis of subjects with pre-capillary PH only. A total of six studies met the inclusion criteria, with a sample size of 13,987 patients. Obese subjects had lower mortality compared to non-obese subjects in the combined pre- and post-capillary PH group (hazard ratio 0.79, 95% CI 0.66-0.95, = 0.01). While obesity was associated with reduction in mortality in the pre-capillary PH group (hazard ratio 0.77, 95% CI 0.60 to 0.98, = 0.03), this was not uniform across all studies.

Meta-Analysis
OBJECTIVE
This systematic review and meta-analysis aimed to evaluate the clinical effectiveness of low-dose aspirin combined with calcium supplements for the prevention of preeclampsia.
METHODS
China National Knowledge Infrastructure, VIP, Wanfang, PubMed, EMBASE, and Cochrane Library databases were searched from inception until December 2022. Randomized controlled trials investigating the preventive use of aspirin in combination with calcium supplementation for preeclampsia in high-risk pregnant women were included. The quality of the literature was evaluated, and a meta-analysis was conducted using RevMan 5.3 software to analyze the clinical efficacy of low-dose aspirin combined with calcium supplementation in preventing preeclampsia.
RESULTS
Seven randomized controlled trials were included in this meta-analysis, and compared with the control group, the experimental group had lower incidence rates of preeclampsia with gestational hypertension (odds ratios [OR]: 0.17, 95% confidence interval [CI]: 0.11-0.28), preeclampsia (OR: 0.20, 95% CI: 0.10-0.37), gestational hypertension (OR: 0.15, 95% CI: 0.07-0.31), preterm birth (OR: 0.26, 95% CI: 0.16-0.44), postpartum hemorrhage (OR: 0.15, 95% CI: 0.08-0.27), and fetal growth restriction (OR: 0.16, 95% CI: 0.08-0.33).
CONCLUSION
Compared with aspirin alone, low-dose aspirin combined with calcium supplementation was more effective in preventing preeclampsia, reduced the risk of preterm birth and postpartum hemorrhage, and promoted fetal growth. This intervention has clinical value and should be considered for high-risk pregnant women.

Meta-Analysis
AIMS/HYPOTHESIS
To provide a systematic overview of the current body of evidence on high-risk phenotypes of diabetes associated with COVID-19 severity and death.
METHODS
This is the first update of our recently published living systematic review and meta-analysis. Observational studies investigating phenotypes in individuals with diabetes and confirmed SARS-CoV-2 infection with regard to COVID-19-related death and severity were included. The literature search was conducted from inception up to 14 February 2022 in PubMed, Epistemonikos, Web of Science and the COVID-19 Research Database and updated using PubMed alert to 1 December 2022. A random-effects meta-analysis was used to calculate summary relative risks (SRRs) with 95% CIs. The risk of bias was evaluated using the Quality in Prognosis Studies (QUIPS) tool and the certainty of evidence using the GRADE approach.
RESULTS
A total of 169 articles (147 new studies) based on approximately 900,000 individuals were included. We conducted 177 meta-analyses (83 on COVID-19-related death and 94 on COVID-19 severity). Certainty of evidence was strengthened for associations between male sex, older age, blood glucose level at admission, chronic insulin use, chronic metformin use (inversely) and pre-existing comorbidities (CVD, chronic kidney disease, chronic obstructive pulmonary disease) and COVID-19-related death. New evidence with moderate to high certainty emerged for the association between obesity (SRR [95% CI] 1.18 [1.04, 1.34], n=21 studies), HbA (53-75 mmol/mol [7-9%]: 1.18 [1.06, 1.32], n=8), chronic glucagon-like peptide-1 receptor agonist use (0.83 [0.71, 0.97], n=9), pre-existing heart failure (1.33 [1.21, 1.47], n=14), pre-existing liver disease (1.40 [1.17, 1.67], n=6), the Charlson index (per 1 unit increase: 1.33 [1.13, 1.57], n=2), high levels of C-reactive protein (per 5 mg/l increase: 1.07 [1.02, 1.12], n=10), aspartate aminotransferase level (per 5 U/l increase: 1.28 [1.06, 1.54], n=5), eGFR (per 10 ml/min per 1.73 m increase: 0.80 [0.71, 0.90], n=6), lactate dehydrogenase level (per 10 U/l increase: 1.03 [1.01, 1.04], n=7) and lymphocyte count (per 1×10/l increase: 0.59 [0.40, 0.86], n=6) and COVID-19-related death. Similar associations were observed between risk phenotypes of diabetes and severity of COVID-19, with some new evidence on existing COVID-19 vaccination status (0.32 [0.26, 0.38], n=3), pre-existing hypertension (1.23 [1.14, 1.33], n=49), neuropathy and cancer, and high IL-6 levels. A limitation of this study is that the included studies are observational in nature and residual or unmeasured confounding cannot be ruled out.
CONCLUSIONS/INTERPRETATION
Individuals with a more severe course of diabetes and pre-existing comorbidities had a poorer prognosis of COVID-19 than individuals with a milder course of the disease.

Meta-Analysis Review
An evaluation of the efficacy and the safety of home blood pressure monitoring in the control of hypertensive disorders of pregnancy in both pre and postpartum periods: a systematic review and meta-analysis.
BACKGROUND
Hypertensive disorders of pregnancy (HDP) can significantly impact maternal, neonatal, and fetal health. For controlling these disorders, frequent blood pressure measurements are required. Home blood pressure monitoring (HBPM) is a suggested alternative to conventional office monitoring that requires frequent visits. This systematic review was conducted to evaluate the efficacy and safety of HBPM in the control of HDP.
METHODS
We systematically conducted databases search for relevant studies in June 2022. The relevant studies were identified, and qualitative synthesis was performed. An inverse variance quantitative synthesis was conducted using RevMan software. Continuous outcome data were pooled as means differences, whereas dichotomous ones were summarized as risk ratios. The 95% confidence interval was the measure of variance.
RESULTS
Fifteen studies were included in our review (n = 5335). Our analysis revealed a superiority of HBPM in reducing the risk of induction of labor, and postpartum readmission (P = 0.02, and 0.01 respectively). Moreover, the comparison of birth weights showed a significant variation in favor of HBPM (P = 0.02). In the analysis of other outcomes, HBPM was equally effective as office monitoring. Furthermore, HBPM did not result in an elevated risk of maternal, neonatal, and fetal adverse outcomes.
CONCLUSION
Home monitoring of blood pressure showed superiority over office monitoring in some outcomes and equal efficacy in other outcomes.

Meta-Analysis
BACKGROUND
Hypertension is the global, leading cause of mortality and is the main risk factor for cardiovascular disease. Community-based partnerships can provide cost-saving ways of delivering effective blood pressure (BP) interventions to people in resource-poor settings. Faith-based organisations (FBOs) prove important potential health partners, given their reach and community standing. This potential is especially strong in hard-to-reach, socio-economically marginalised communities. This systematic review explores the state of the evidence of FBO-based interventions on BP management, with a focus on randomised controlled trials (RCTs) and cluster RCTs (C-RCTs).
METHODS
Seven academic databases (English = 5, Chinese = 2) and grey literature were searched for C-/RCTs of community-based interventions in FBO settings. Only studies with pre- and post-intervention BP measures were kept for analysis. Random effects models were developed using restricted maximum likelihood estimation (REML) to estimate the population average mean change and 95% confidence interval (CI) of both systolic and diastolic blood pressure (SBP and DBP). The overall heterogeneity was assessed by successively adding studies and recording changes in heterogeneity. Prediction intervals were generated to capture the spread of the pooled effect across study settings.
RESULTS
Of the 19 055 titles identified, only 11 studies of fair to good quality were kept for meta-analysis. Non-significant, average mean differences between baseline and follow-up for the intervention and control groups were found for both SBP (0.78 mm of mercury (mmHg) (95% CI = 2.11-0.55)) and DBP (-0.20 mm Hg (95% CI = -1.16 to 0.75)). Subgroup analysis revealed a significant reduction in SBP of -6.23 mm Hg (95% CI = -11.21 to -1.25) for populations with mean baseline SBP of ≥140 mm Hg.
CONCLUSIONS
The results support the potential of FBO-based interventions in lowering SBP in clinically hypertensive populations. However, the limited evidence was concentrated primarily in Christian communities in the US More research is needed to understand the implications of such interventions in producing clinically meaningful long-term effects in a variety of settings. Further research can illuminate factors that affect success and potential expansion to sites outside the US as well as non-Christian FBOs. Current evidence is inadequate to evaluate the potential of FBO-based interventions in preventing hypertension in non-hypertensive populations. Intervention effects in non-hypertensive population might be better reflected through intermediate outcomes.

Meta-Analysis Review
BACKGROUND
Maternal high blood pressure (BP) was associated with adverse pregnancy outcomes. This study aimed to synthesize evidence on the association between high BP prior to or in early pregnancy with maternal and fetal complications.
METHODS
We searched the cohort studies assessing the effect of high BP in the Medline, Embase, Web of Science and China National Knowledge Internet databases. A random-effects model was used to estimate the pooled odds ratios (ORs) with 95% confidence intervals (CIs). The protocol was registered in PROSPERRO (CRD 42023414945).
RESULTS
23 eligible studies were identified. High BP prior to or in early pregnancy was associated with higher odds of hypertensive disorders of pregnancy (OR 2.90, 95% CI 1.91-3.89), gestational hypertension (2.56, 2.01-3.12), preeclampsia (3.20, 2.66-3.74), gestational diabetes mellitus (1.71, 1.36-2.06), preterm birth (1.66, 1.39-1.93), stillbirth (2.01, 1.45-2.58) and neonatal intensive care unit admission (1.22, 1.08-1.37). Subgroup analyses indicated that pre-hypertension could significantly increase the odds of these outcomes except for stillbirth, though the odds were lower than hypertension.
CONCLUSIONS
High BP prior to or in early pregnancy was associated with adverse pregnancy outcomes and this association increased with hypertension severity. The findings emphasized an urgent need for heightened surveillance for maternal BP, especially pre-hypertensive status.
