Association of estimated plasma volume with new onset acute kidney injury in hospitalized COVID-19 patients

PurposeTo explore the association of estimated plasma volume (ePV) and plasma volume status (PVS) as surrogates of volume status with new-onset AKI and in-hospital mortality among hospitalized COVID-19 patients. Materials and methodsWe performed a retrospective multi-center study on COVID-19-related ARDS patients who were admitted to the Mayo Clinic Enterprise health system. Plasma volume was calculated using the formulae for ePV and PVS, and longitudinal analysis was performed to find the association of ePV and PVS with new-onset AKI during hospitalization as the primary outcome and in-hospital mortality as a secondary outcome. ResultsOur analysis included 7616 COVID-19 patients with new-onset AKI occurring in 1365 (17.9 %) and a mortality rate of 25.96 % among them. A longitudinal multilevel multivariate analysis showed both ePV (OR 1.162; 95 % CI 1.048–1.288, p = 0.004) and PVS (OR 1.032; 95 % CI 1.012–1.050, p = 0.001) were independent predictors of new onset AKI. Higher PVS was independently associated with increased in-hospital mortality (OR 1.038, 95 % CI 1.007–1.070, p = 0.017), but not ePV (OR 0.868, 95 % CI 0.740–1.018, p = 0.082). ConclusionA higher PVS correlated with a higher incidence of new-onset AKI and worse outcomes in our cohort of hospitalized COVID-19 patients. Further large-scale and prospective studies are needed to understand its utility.

The receipt of health information on neonatal dangers signs during the immediate postpartum period and its determinants in Ethiopia: a multilevel mixed-effects logistic regression analysis of the 2016 Ethiopian demographic health survey report

BackgroundIdentification of neonatal danger signs and immediate access to health care are two global efforts aimed at enhancing newborn and child survival by preventing 75% of neonatal deaths. Despite various small-scale studies on women’s awareness of neonatal danger signs in Ethiopia, little is known about the level of receiving health information on those danger signs during the immediate postpartum period at the national level. Hence, this study aimed at assessing the level, and its determinants of the service uptake in Ethiopia.MethodsThe data for this study was taken from the Ethiopian Demographic and Health Survey (EDHS), which took place from January to June 2016 and covered all administrative regions of Ethiopia. A weighted sample of 7,589.8 women was analyzed using STATA version 16. To account for data clustering, a multivariable multilevel mixed-effect logistic regression analysis was employed to determine the effects of each predictor on the outcome variable. Adjusted odds ratio with its corresponding 95% confidence interval was used to declare the statistical significance of the explanatory variables.ResultsThe receipt of health information on neonatal danger signs during the immediate postpartum period was 10.70% [95% CI:10.01, 11.40]. Variables namely living in Metropolitans [AOR = 2.06; 95%CI: 1.48, 2.88] and Large central [AOR = 1.83; 95%CI: 1.38, 2.42] regions, being in the highest wealth quintile [AOR = 1.87; 95% CI: 1.23, 2.84], being nulliparous [AOR = 0.27; 95% CI: 0.08, 0.87] and primiparous[AOR = 0.61;95% CI: 0.46, 0.79], getting adequate antenatal visits [AOR = 2.42; 95% CI: 1.75, 3.33], institutional delivery [AOR = 5.91; 95% CI: 4.66, 7.53], and receipt of postnatal visits [AOR = 3.52; 95% CI: 2.84, 4.38] were identified as significant determinants of receiving health information on newborn danger signs.ConclusionThe findings revealed that unacceptably low uptake of health information on newborn danger signs during the immediate postpartum period in Ethiopia. A concerted effort is needed from all stakeholders in the health sector to enhance the uptake of maternal health services (antenatal care, skilled delivery service, and postnatal care). Healthcare providers should pay special attention to nulliparous and primiparous women during and after delivery, and the government should also focus on women of peripheral regions, who make up a large portion of the low coverage.

Prevalence of multiple micronutrient powders consumption and its determinants among 6- to 23-month-old children in East Africa: a mixed effect analysis using the recent population based cross sectional national health survey

BackgroundTo address iron deficiency anemia, Multiple Micronutrient Powders (MMNPs) can be sprinkled onto any semisolid diet and given to young children. There is currently no data on actual MMNPs uptake by children; hence, the study’s goal was to investigate MMNPs and determinants among children aged 6–23 months in East Africa.MethodsData from the 2016–2022 East Africa demographic and health survey extracted from Kids Records (KR) files were used in this study. A total of 33,324 weighted 6- to 23-month-old child samples were included. For assessing model fitness and contrast, the intra-class correlation coefficient, median odds ratio, proportional change in variance, and deviance were used. A multilevel logistic regression model was applied to identify variables that may influence MMNPs intake. In the multivariable multilevel logistic regression analyses, variables were judged to be significantly linked with MMNPs intake if their p-values were < 0.05.ResultsIn East Africa, the prevalence of MMNPs intake among infants aged 6–23 months was 6.45% (95% CI, 6.19%, 6.22%). Several factors were found to be significantly associated with MMNPs consumption. These factors include older maternal age (AOR = 1.23, 95% CI, 1.09, 1.39) and (AOR = 1.46, 95% CI, 1.23, 1.73), poorer (AOR = 0.73, 95% CI, 0.64, 0.84), middle (AOR = 0.75, 95% CI, 0.66, 0.86), richer (AOR = 0.61, 95% CI, 0.52, 0.71), and richest (AOR = 0.49, 95% CI, 0.41, 0.59) as compared to poorest, having employment status (AOR = 0.65, 95% CI, 0.59, 0.71), mass media exposure (AOR = 1.61, 95% CI, 1.35, 1.78), longer birth interval (AOR = 1.19, 95% CI, 1.28, 1.36), place of delivery (AOR = 1.46, 95% CI, 1.28,1.66), and mothers from rural areas (AOR = 0.71, 95% CI, 0.62,0.80).ConclusionsOverall, MMNPs intake was lower than the national and international recommendations. Only seven out of every hundred children received MMNPs. Improving maternal preventive health care and supporting marginalized women will have a positive impact.

Multilevel analysis on prevalence and associated factors of modern contraceptive uptake in Somaliland: based on The Somaliland Health and Demographic Survey 2020

IntroductionContraception is the deliberate prevention of unwanted pregnancy through various contraceptive methods. Its uptake is low in Sub-Saharan African countries, particularly in east Africa. This might be linked to the high prevalence of unwanted pregnancies and the high fertility rate in the area. Although studies reporting the prevalence and associated factors of modern contraceptive uptake are available in other African countries, no study has been conducted in Somaliland. Therefore, the current study aimed to assess its prevalence and associated factors in Somaliland using Somaliland Health and Demographic Survey (SLHDS) data.Methods and materialsThe study used Somaliland Demographic Health Survey (SLDHS) 2020 data. The survey was a national-level survey using a cross-sectional study design. A total of 3656 reproductive-age women were included in the current study. To determine independent predictors of modern contraceptive uptake, a multi-level multivariable logistic regression analysis was done. Random effect analysis, standard error (SE) and intra-cluster correlation (ICC) were computed.ResultsThe proportion of modern contraceptive uptake among reproductive age groups in Somaliland is 1%. Modern contraceptive uptake is significantly associated with the residence, educational level and wealth index of participants. Women from nomadic communities had lower odds (AOR: 0.25; 95% CI: 0.10, 0.66) of modern contraceptive uptake compared to those from urban areas. Being in the highest wealth quintiles (AOR: 17.22; 95% CI: 1.99, 155.92) and having a tertiary educational level (AOR: 2.11; 95% CI: 1.29, 9.11) had higher odds of using the modern contractive method compared to those with the lowest wealth quintiles and non-formal education, respectively.ConclusionThe prevalence of modern contraceptive uptake in Somaliland was very low. It is associated with the level of education, wealth index and residence of the women.

A multilevel analysis of the determinants of HIV testing among men in Sub-Saharan Africa: Evidence from Demographic and Health Surveys across 10 African countries.

Sub-Saharan Africa, the epicenter of the HIV epidemic, has seen significant reductions in new infections over the last decade. Although most new infections have been reported among women, particularly adolescent girls, men are still disadvantaged in accessing HIV testing, care, and treatment services. Globally, men have relatively poorer HIV testing, care, and treatment indices when compared with women. Gender norms and the associated concept of masculinity, strength, and stereotypes have been highlighted as hindering men's acceptance of HIV counseling and testing. Therefore, men's suboptimal uptake of HIV testing services will continue limiting efforts to achieve HIV epidemic control. Thus, this study aimed to identify individual, neighborhood, and country-level determinants of sub-optimal HIV testing among men in Sub-Saharan African countries. We analyzed demographic and health datasets from surveys conducted between 2016 and 2020 in Sub-Saharan African Countries. We conducted multivariable multilevel regression analysis on 52,641 men aged 15-49 years resident in 4,587 clusters across 10 countries. The primary outcome variable was ever tested for HIV. HIV testing services uptake among men in these ten Sub-Saharan African countries was 35.1%, with a high of 65.5% in Rwanda to a low of 10.2% in Guinea. HIV testing services uptake was more likely in men with increasing age, some form of formal education, in employment, ever married, and residents in relatively wealthier households. We also found that men who possessed health insurance, had some form of weekly media exposure, and had accessed the internet were more likely to have ever received an HIV test. Unlike those noted to be less likely to have ever received an HIV test if they had discriminatory attitudes towards HIV, comprehensive HIV knowledge, recent sexual activity, and risky sexual behavior were positive predictors of HIV testing services uptake among men. Furthermore, men in communities with high rurality and illiteracy were less likely to receive an HIV test. Individual and community-level factors influence the uptake of HIV testing among Sub-Saharan African men. There was evidence of geographical clustering in HIV testing uptake among men at the community level, with about two-thirds of the variability attributable to community-level factors. Therefore, HIV testing programs will need to design interventions that ensure equal access to HIV testing services informed by neighborhood socioeconomic conditions, peculiarities, and contexts.

Multilevel multinomial regression analysis of factors associated with birth weight in sub-Saharan Africa

Birth weight significantly determines newborns immediate and future health. Globally, the incidence of both low birth weight (LBW) and macrosomia have increased dramatically including sub-Saharan African (SSA) countries. However, there is limited study on the magnitude and associated factors of birth weight in SSA. Thus, thus study investigated factors associated factors of birth weight in SSA using multilevel multinomial logistic regression analysis. The latest demographic and health survey (DHS) data of 36 sub-Saharan African (SSA) countries was used for this study. A total of a weighted sample of 207,548 live births for whom birth weight data were available were used. Multilevel multinomial logistic regression model was fitted to identify factors associated with birth weight. Variables with p-value < 0.2 in the bivariable analysis were considered for the multivariable analysis. In the multivariable multilevel multinomial logistic regression analysis, the adjusted Relative Risk Ratio (aRRR) with the 95% confidence interval (CI) was reported to declare the statistical significance and strength of association. The prevalence of LBW and macrosomia in SSA were 10.44% (95% CI 10.31%, 10.57%) and 8.33% (95% CI 8.21%, 8.45%), respectively. Maternal education level, household wealth status, age, and the number of pregnancies were among the individual-level variables associated with both LBW and macrosomia in the final multilevel multinomial logistic regression analysis. The community-level factors that had a significant association with both macrosomia and LBW were the place of residence and the sub-Saharan African region. The study found a significant association between LBW and distance to the health facility, while macrosomia had a significant association with parity, marital status, and desired pregnancy. In SSA, macrosomia and LBW were found to be major public health issues. Maternal education, household wealth status, age, place of residence, number of pregnancies, distance to the health facility, and parity were found to be significant factors of LBW and macrosomia in this study. Reducing the double burden (low birth weight and macrosomia) and its related short- and long-term effects, therefore, calls for improving mothers' socioeconomic status and expanding access to and availability of health care.

Predictors of maternal health services uptake in West African region: a multilevel multinomial regression analysis of demographic health survey reports

BackgroundPursuant to studies, receiving the three key maternal health services (Antenatal Care, Skilled Delivery Service, and Postnatal Care) in a continuum could prevent 71% of global maternal deaths. Despite the Western African region being known for its high maternal death and poor access to maternal health services, there is a dearth of studies that delve into the spectrum of maternal health services uptake. Hence, this study aimed to assess the level and predictors of partial and adequate utilization of health services in a single analytical model using the most recent Demographic and Health Survey (DHS) data (2013–2021).MethodsThis study was based on the appended women's (IR) file of twelve West African countries. STATA software version 16 was used to analyze a weighted sample of 89,504 women aged 15–49 years. A composite index of maternal health service utilization has been created by combining three key health services and categorizing them into ‘no’, ‘partial’, or ‘adequate’ use. A multilevel multivariable multinomial logistic regression analysis was carried out to examine the effects of each predictor on the level of service utilization. The degree of association was reported using the adjusted relative risk ratio (aRRR) with a corresponding 95% confidence interval, and statistical significance was declared at p < 0.05.Results66.4% (95% CI: 64.9, 67.7) and 23.8% (95% CI: 23.3, 24.2) of women used maternal health services partially and adequately, respectively. Togo has the highest proportion of women getting adequate health care in the region, at 56.7%, while Nigeria has the lowest proportion, at 11%. Maternal education, residence, wealth index, parity, media exposure (to radio and television), enrolment in health insurance schemes, attitude towards wife beating, and autonomy in decision-making were identified as significant predictors of partial and adequate maternal health service uptake.ConclusionThe uptake of adequate maternal health services in the region was found to be low. Stakeholders should plan for and implement interventions that increase women's autonomy. Program planners and healthcare providers should give due emphasis to those women with no formal education and from low-income families. The government and the private sectors need to collaborate to improve media access and increase public enrolment in health insurance schemes.

Low-risk Staphylococcus aureus bacteremia patients do not require routine diagnostic imaging: A multicenter retrospective cohort study.

Risk stratification to categorize patients with Staphylococcus aureus bacteremia (SAB) as low- or high-risk for metastatic infection may direct diagnostic evaluation and enable personalized management. We investigated the frequency of metastatic infections in low-risk SAB patients, their clinical relevance, and whether omission of routine imaging is associated with worse outcomes. We performed a retrospective cohort study in seven Dutch hospitals among adult patients with low-risk SAB, defined as hospital-acquired infection without treatment delay, absence of prosthetic material, short duration of bacteremia, and rapid defervescence. The primary outcome was the proportion of patients whose treatment plan changed due to detected metastatic infections, as evaluated by both the actual therapy administered and by linking a retrospectively adjudicated diagnosis to guideline-recommended treatment. Secondary outcomes were 90-day relapse-free survival, and factors associated with performing of diagnostic imaging. Of 377 patients included, 298 (79%) underwent diagnostic imaging. In 15 of these 298 patients (5.0%) imaging findings during patient admission had been interpreted as metastatic infections that should extend duration of treatment. Using the final adjudicated diagnosis, 4 patients (1.3%) had clinically relevant metastatic infection. In a multilevel multivariable logistic regression analysis, 90-days relapse-free survival was similar between patients without imaging and those who underwent imaging (81.0% versus 83.6%; aOR 0.749 (95% CI 0.373-1.504). Our study advocates risk stratification for the management of patients with SAB. Prerequisites are follow-up blood cultures, bedside ID consultation, along with critically reviewing disease evolution. Using this approach, routine imaging could be omitted in low-risk patients.

What makes mentors thrive? An exploratory study of their satisfaction in undergraduate medical education

BackgroundMentoring medical students with varied backgrounds and individual needs can be challenging. Mentors’ satisfaction is likely to be important for the quality and sustainability of mentorships, especially in programs where the mentor has responsibility for facilitating a group of mentees. However, little is known about what influences mentors’ satisfaction. The aim of this study was to measure mentors’ self-reported satisfaction with the mentoring experience and to explore associations between satisfaction and its putative factors.MethodsAn online survey was sent out to all physician mentors in each of the three mentorship programs (UiT The Arctic University of Norway, the University of Bergen, and McGill University, graduation years 2013–2020, n = 461). Data were analyzed by descriptive statistics, dimension reduction, and linear regression.ResultsOn a scale from 1 to 5, mean mentor satisfaction score at two Norwegian and one Canadian medical school was 4.55 (95% CI 4.47, 4.64). In a multilevel multivariate regression analysis, two predictors were significantly associated with mentors’ satisfaction: (1) the perception that students found the group meetings valuable (β = 0.186, 95% CI 0.021, 0.351, p = 0.027) and (2) mentors’ perceived rewards (β = 0.330, 95% CI 0.224, 0.437, p < 0.001). Perceived rewards included experiencing gratifying relationships with students, and mentors’ perception of self-development.ConclusionsIn this study, mentors appeared to be highly satisfied with their mentoring functions. Our findings suggest that mentors’ overall satisfaction is closely linked to their experiences of fulfilling mentor-student relationships and personal and professional development. Interestingly, and perhaps contrary to commonly held assumptions, we found no association between mentor satisfaction and financial compensation. Furthermore, satisfaction was not associated with the provision of pre-assigned topics for discussions for mentor group meetings. We propose that the mentors’ experienced psycho-social rewards, and their competence in establishing well-functioning group dynamics, should be areas of focus for faculty development.

Individual and school correlates of body mass index and cardiorespiratory fitness in primary school children from the REACT project: A multivariate multilevel analysis.

This paper examines the relationship between body mass index (BMI) and cardiorespiratory fitness (CRF) using a multivariate multilevel approach and investigates the links between individual and school-related correlates with children's BMI and CRF. This cross-sectional sample included 1014 children (6-10 years) from 25 Portuguese primary schools. BMI was calculated, and CRF was assessed with the PACER test. Fundamental movement skills (FMS) included five object control tasks. Moderate-to-vigorous physical activity (MVPA), sleep, and sedentary time were assessed with the ActiGraph wGT3X-BT accelerometer. Socioeconomic status (SES) and school variables were also obtained. A multivariate multilevel model was used, and alpha was set at 5%. BMI and CRF systematically increased with age. Most of the joint variance (94.4%) was explained at the child level, and BMI and CRF were correlated at this level (ρ = -.37). More active children demonstrated higher CRF levels and had lower BMI levels; sedentary and sleep time were not significantly associated with BMI or CRF. FMS were positively associated with CRF but were not significantly associated with BMI. Children at higher SES were more fit and had lower BMI than their peers of lower SES. Finally, school-level variables were not significantly related to BMI and CRF. BMI and CRF had a low but statistically significant negative correlation in this sample of children. Most of the variation in BMI and CRF was explained by child-level characteristics.

Towards Equal Access to Cytoreductive Surgery with Hyperthermic Intraperitoneal Chemotherapy and Survival in Patients with Isolated Colorectal Peritoneal Metastases: A Nationwide Population-Based Study

BackgroundBefore 2016, patients with isolated synchronous colorectal peritoneal metastases (PMCRC) diagnosed in expert centers had a higher odds of undergoing cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) and better overall survival (OS) than those diagnosed in referring centers. Nationwide efforts were initiated to increase awareness and improve referral networks.MethodsThis nationwide study aimed to evaluate whether the between-center differences in odds of undergoing CRS-HIPEC and OS have reduced since these national efforts were initiated. All patients with isolated synchronous PMCRC diagnosed between 2009 and 2021 were identified from the Netherlands Cancer Registry. Associations between hospital of diagnosis and the odds of undergoing CRS-HIPEC, as well as OS, were assessed using multilevel multivariable regression analyses for two periods (2009–2015 and 2016–2021).ResultsIn total, 3948 patients were included. The percentage of patients undergoing CRS-HIPEC increased from 17.2% in 2009–2015 (25.4% in expert centers, 16.5% in referring centers), to 23.4% in 2016–2021 (30.2% in expert centers, 22.6% in referring centers). In 2009–2015, compared with diagnosis in a referring center, diagnosis in a HIPEC center showed a higher odds of undergoing CRS-HIPEC (odds ratio [OR] 1.64, 95% confidence interval [CI] 1.02–2.67) and better survival (hazard ratio [HR] 0.80, 95% CI 0.66–0.96). In 2016–2021, there were no differences in the odds of undergoing CRS-HIPEC between patients diagnosed in HIPEC centers versus referring centers (OR 1.27, 95% CI 0.76–2.13) and survival (HR 1.00, 95% CI 0.76–1.32).ConclusionPreviously observed differences in odds of undergoing CRS-HIPEC were no longer present. Increased awareness and the harmonization of treatment for PMCRC may have contributed to equal access to care and a similar chance of survival at a national level.

Prevalence and Predictors of Burnout Among Resident Family Physicians.

Resident burnout may affect career choices and empathy. We examined predictors of burnout among family medicine residents. We used data from the 2019-2021 American Board of Family Medicine Initial Certification Questionnaire, which is required of graduating residents. Burnout was a binary variable defined as reporting callousness or emotional exhaustion once a week or more. We evaluated associations using bivariate and multilevel multivariable regression analyses. Among 11,570 residents, 36.4% (n=4,211) reported burnout. This prevalence did not significantly vary from 2019 to 2021 and was not significantly attributable to the residency program (ICC=0.07). Residents identifying as female reported higher rates of burnout (39.0% vs 33.4%, AOR=1.29 [95% CI 1.19-1.40]). Residents reporting Asian race (30.5%, AOR=0.78 [95% CI 0.70-0.86]) and Black race (32.3%, AOR=0.71 [95% CI 0.60-0.86]) reported lower odds of burnout than residents reporting White race (39.2%). We observed lower rates among international medical graduates (26.7% vs 40.3%, AOR=0.54 [95% CI 0.48-0.60]), those planning to provide outpatient continuity care (36.0% vs 38.7%, AOR=0.77 [95% CI 0.68-0.86]), and those at smaller programs (31.7% for &lt;6 residents per class vs 36.3% for 6-10 per class vs 40.2% for &gt;10 per class). Educational debt greater than $250,000 was associated with higher odds of burnout than no debt (AOR=1.29 [95% CI 1.15-1.45]). More than one-third of recent family medicine residents reported burnout. Odds of burnout varied significantly with resident and program characteristics.

Statin use and mortality in patients with deep vein thrombosis. Data from the RIETE Registry

BackgroundThe association between statin use and mortality in patients with deep vein thrombosis (DVT) has not been rigorously evaluated. MethodsWe used the data in the RIETE registry to examine the association between statin use and mortality at 3 months. We used mixed effects survival models accounting for clinical covariates and clustering of patients in enrolling centers. ResultsFrom January 2009 through April 2022, there were 46,440 patients with isolated DVT in RIETE (in the lower-limbs 42,291, in the upper limbs 4149). Of these, 21 % and 18 %, respectively, were using statins. Statin users were older than non-users (72 ± 12 vs. 62 ± 18 years), and more likely had diabetes, hypertension, prior myocardial infarction or ischemic stroke, or were receiving antiplatelets. The 3-month mortality rates were: 6.0 % vs. 5.8 %, respectively. On multilevel multivariable analysis, the adjusted hazard ratio (aHR) for all-cause death in statin users vs. non-users was 0.77 (95%CI: 0.69–0.86). The 3-month risk of death in statin users was significantly lower than in non-users in patients with upper-limb DVT (aHR: 0.81; 95%CI: 0.72–0.91), distal lower-limb DVT (aHR: 0.48; 95%CI: 0.32–0.72), or proximal lower-limb DVT (aHR: 0.69; 95%CI: 0.50–0.95), and in those receiving simvastatin (aHR: 0.73; 95%CI: 0.60–0.90), atorvastatin (aHR: 0.70; 95%CI: 0.59–0.85), or rosuvastatin (aHR: 0.47; 95%CI: 0.27–0.80). Major bleeding, used as a falsification endpoint, did not show an association with use of statins at 3-month follow-up. ConclusionsStatin users with isolated DVT were at significantly lower risk for death at 3 months than non-users.

The impact of clinical and laboratory parameters on clinical pregnancy and live birth rates in fresh cycles: a retrospective study of 9608 high-quality cleavage-stage embryos

BackgroundEvidence from the Istanbul consensus workshop suggests correlations between morphological parameters and embryo developments. 8-cell embryos are the best blastomere stage on day 3. No good quality evidence exists to support high-quality embryonic selection following blastulation and clinical outcomes. This study aimed to investigate the factors that affect blastocyst formation, blastocyst quality, and clinical outcomes of high-quality cleavage-stage embryos in fresh cycles.MethodsThis study was a retrospective analysis of 9608 high-quality cleavage-stage embryos from 2987 couples between January 2017 to June 2021, namely 1520 embryos categorized as “812” (8-cell, grade 2, mild fragmentation), 2961 as “821” (8-cell, grade 2, mild asymmetry), 896 as “711” (7-cell, grade 1), and 517 as “911” (9-cell, grade 1) compared with 3714 embryos categorized as “811” (8-cell, grade 1). The primary outcomes were clinical pregnancy rate (CPR) and live birth rate (LBR). Blastulation rate (BR), available late blastocyst rate (ABR) and high-quality late blastocyst rate (HBR) were secondary outcome measures.ResultsBR, ABR, and HBR had significant differences among the five groups (P < 0.001), while CPR and LBR were also significantly different in cleavage-stage fresh transfer (P < 0.01). The multivariable multilevel logistic regression analysis revealed a significant association between cell number, cell size, blastocyst development and clinical outcomes. For 7 to 9-cell highest-quality embryo, mild fragmentation and more blastomeres were more conducive to blastocyst formation and clinical outcomes. While cleavage-stage embryos developed into blastocysts, the negative impact of their initial morphology on clinical outcomes would be erased.ConclusionsOur study firstly evaluated blastocyst development and clinical outcomes of high-quality cleavage-stage embryos in fresh cycles, with rankings of 811, 812, 911, 821, and 711. We found the initial morphological characteristics of the high-quality cleavage-stage embryos did not adversely impact clinical outcomes, even as they progressed to the blastocyst stage.

Pressurizing or encouraging: Health behaviors among long-distance couples.

Couples in long-distance relationships face unique challenges that affect their health outcomes and relationship dynamics in ways that are different from couples in close proximal relationships (PR). The results of previous literature analyzing health outcomes for long-distance relationship (LDR) couples have been mixed, and factors such as couple satisfaction and gender of the individuals contribute to the variance. This study examined the good health practices of couples in LDRs, the ways in which partners influence each other's health, and the health outcomes of these couples as compared to couples in PRs. Multilevel multivariate analysis showed that couples in LDRs had better health practices than those in PRs, and men overall had poorer health practices than women. There was no main effect seen for LDRs when we examined strategies used for influencing health. There was a main effect for gender, though, and we found that women tend to use more collaborative and pressurizing strategies for influencing their partner's health. On health indices, we found that LDR couples tended to have lower levels of fatigue and sleep disturbance as compared to PR couples. In the adjusted model with covariates, which included age, income, couple satisfaction, and married or unmarried couples, we found that lower couple satisfaction and lower income significantly predicted poorer health on all health indices. These results are discussed in light of unequal gender roles, social control, and positive aspects of LDRs on health in an attempt to understand LDRs better and destigmatize the narrative of these relationships as 'less than' PRs. Implications for health and mental health practitioners are also discussed.

Spatial distribution and determinants of unmet need for family planning among all reproductive‑age women in Uganda: a multi‑level logistic regression modeling approach and spatial analysis

IntroductionUnmet need for family planning is defined as the percentage of sexually active and fecund women who want to delay the next birth (birth spacing) or who want to stop childbirth (birth limiting) beyond two years but who are not using any modern or traditional method of contraception. Despite the provision of family planning services, the unmet need of family planning remains a challenge in low- and middle-income countries (LMICs). Thus, this study aimed to assess the spatial distribution and determinant factors of unmet need for family planning among all reproductive‑age women in Uganda.MethodsA secondary data analysis was done based on 2016 Ugandan Demographic and Health Surveys (UDHS). Total weighted samples of 18,506 women were included. Data processing and analysis were performed using SPSS Version 26, STATA 14.2, ArcGIS 10.8, and SaTScan 10.1.2 software. Spatial autocorrelation and hotspot analysis was made using Global Moran’s index (Moran’s I) and Gettis-OrdGi*statistics, respectively. Determinants of unmet needs for family planning were identified by multi-level logistic regression analysis. Variables with a p-value < 0.05 were declared statistically significant predictors.ResultsThe spatial distribution of unmet need for family planning among women of reproductive age in Uganda was found to be clustered (Global Moran’s I = 0.27, Z-score of 12.71, and p-value < 0.0001). In the multivariable multilevel logistic regression analysis; women in West Nile (AOR = 1.86, 95% CI: 1.39, 2.47), aged 25–49 years old (AOR = .84; 95% CI .72, .99), highly educated (AOR = .69; 95% CI .54, .88), Muslim (AOR = 1.20, 95% CI: 1.03, 1.39), high wealth status (AOR = .73, 95% CI: .64, .82), and had five or more living child (AOR = 1.69, 95% CI: 1.51, 1.88) were significant predictors of unmet need for family planning. Significant hotspot areas were identified in West Nile, Acholi, Teso, and Busoga regions.ConclusionA significant clustering of unmet need for family planning were found in Uganda. Moreover, age, educational status, religion, wealth status, number of alive children, and region were significant predictors of unmet need for family planning. Therefore, in order to minimize the burdens associated with unmet need, an interventions focusing on promotion of sexual and reproductive health service should be addressed to the identified hotspot areas.

Compliance towards WHO recommendations on antenatal care for a positive pregnancy experience: Timeliness and adequacy of antenatal care visit in Sub-Saharan African countries: Evidence from the most recent standard Demographic Health Survey data.

Timely and adequate antenatal care (ANC) visits are known to reduce maternal mortality by 20%. Despite the World Health Organization updating its recommendations from four to eight antenatal care contacts, data reporting in the SSA region focused primarily on four visits, and evidence on the timing and adequacy of ANC based on the current recommendation was limited. Hence, this study aimed at assessing the level of timely and adequate ANC visits and their determinants in the 18 Sub-Saharan African countries with the most recent DHS report (2016-2021). The data for this study were pooled from the most recent standardized Demographic and Health Survey data of sub-Saharan African countries from 2016-2021. A total of 171,183 (with a weighted frequency of 171,488) women were included and analyzed by using STATA version 16. To account for data clustering, a multivariable multilevel mixed-effect logistic regression analysis was run to determine the effects of each predictor on the receipt of timely and adequate ANC. Adjusted odds ratio with its corresponding 95% confidence interval was used to declare the statistical significance of the independent variables. The receipt of timely and adequate antenatal care visits was 41.2% (95% CI: 40.9, 41.4) and 10.4% (95% CI: 9.9, 10.2), respectively. Wontedness of pregnancy [AOR = 1.18; 95% CI: 1.13, 1.24], being 1st birth order [AOR = 1.48; 95% CI: 1.41, 2.54], having a mobile phone [AOR = 1.49; 95% CI: 1.26, 2.32], and enrolled in Health insurance schemes [AOR = 2.03; 95% CI: 1.95, 2.42] were significantly associated with early initiation of ANC. Living in a lower community poverty level[AOR = 2.23; 95% CI: 1.90,2.66], being in the richest wealth quintile [AOR = 1.49; 95% CI: 1.36, 1.62], higher educational level [AOR = 3.63; 95% CI: 3.33, 3.96], the timing of ANC visit [AOR = 4.26; 95% CI: 4.08, 4.44], being autonomous in decision making [AOR = 2.29; 95% CI: 1.83, 2.54] and having a mobile phone [AOR = 1.89; 95% CI: 1.76, 2.52] were identified as significant predictors of adequate ANC uptake. The findings revealed a low coverage of timely and adequate ANC visits in SSA countries. Governments and healthcare managers in sub-Saharan African countries should leverage their efforts to prioritize and implement activities and interventions that increase women's autonomy, and economic capability, to improve their health-seeking behavior during pregnancy. More commitment is needed from governments to increase mobile phone distribution across countries, and then work on integrating mHealth into their health system. Finally, efforts should be made to increase the coverage of health insurance schemes enrolment for the citizens.

One month follow-up of carotid endarterectomy with in-hospital preoperative aspirin monotherapy and postoperative dual antiplatelet therapy in asymptomatic and symptomatic patients: A multi-center study

BackgroundThere is currently no consensus regarding the optimal perioperative antiplatelet strategy for carotid artery surgery. This multicentre study aimed to analyse the association between preoperative aspirin monotherapy following postoperative dual antiplatelet therapy (DAPT) and the risk for stroke and death after carotid endarterectomy (CEA). MethodsThis cohort study included 821 patients with carotid artery stenosis who underwent CEA. Primary outcomes included any stroke or death up to the one-month postoperative follow-up. Multilevel multivariate regression analyses and descriptive statistics were performed. ResultsPatients were predominantly male (53 %), with a mean age of 66.2 years. The primary outcome occurred in 1.6 % of patients. Univariate and multivariate analyses revealed that patients with chronic obstructive pulmonary disease (COPD) exhibited a high risk for stroke or death (P = 0.011). The occurrence of any local complications in the neck was accompanied by an increase in diastolic blood pressure (DBP) (P = 0.007). Patients with a high systolic blood pressure (SBP) (P = 0.002) experienced a longer operative duration. The length of hospital stay was longer in the patients with COPD (P = 0.020), minor stroke (P = 0.011), and major stroke (P = 0.001). A positive linear correlation was found between SBP and operative duration in the overall population (β 0.4 [95 % confidence interval (CI) 0.1–0.7]; P = 0.002). The resultant curve for DBP and any local complications in the neck exhibited a two-stage change and one breakpoint in the entire population (k = 68 mmHg, <68; odds ratio [OR] 0.9 [95 % CI 0.7–1.1], P = 0.461; ≥68: OR 1.1 [95 % CI 1.0–1.1], P = 0.003). ConclusionsPreoperative aspirin monotherapy and postoperative DAPT were safe and effective antiplatelet treatments for patients who underwent CEA.

Magnitude and determinant of healthcare-seeking behavior for childhood acute respiratory tract infections in Ethiopia: a cross-sectional study

BackgroundAcute respiratory infections (ARIs) remain a major public health concern which become the leading cause of mortality and morbidity in children under the age of five. A large percentage of childhood deaths and complications can be avoided by seeking proper medical care. Therefore, this study aimed to assess the magnitude, and individual and community-level determinants of mothers’ healthcare-seeking behavior for their children under the age of five who had ARI symptoms in Ethiopia.MethodA secondary data analysis was conducted using the 2016 Ethiopian Demographic and Health Surveys(EDHS) with a total weighted sample of 643 under-five children who had ARI symptoms within two weeks of the survey. Due to the hierarchical nature of the EDHS data, a multi-level logistic regression model was used to identify the individual and community-level factors influencing mothers’ health care-seeking behavior for their children with ARI symptoms. In the multivariable multilevel analysis, those variables with a p-value < 0.05 were considered to be significant predictors of the outcome variable.ResultsHealthcare-seeking behavior among mothers or caregivers for children with symptoms of ARIs was 32.61% (95% CI: 29.08–36.33%) in Ethiopia. The ICC in the null model indicated that about 55% of the total variability of treatment-seeking behavior was due to differences between clusters. Child aged > 24 months [AOR = 0.35; 0.19–0.63], having primary education [AOR = 3.25; 1.27–8.32], being media exposed [AOR = 2.49; 1.15, 5.38], female household head[AOR = 3.90; 1.35, 11.24], and delivery at health institution[AOR = 2.24; 1.00, 5.01] were significant predictors of health care seeking behavior of mother for their children with ARI symptoms.ConclusionThere is poor treatment-seeking behavior for children with symptoms of ARI in Ethiopia with significant community level variations. The multilevel logistic regression analysis showed that improving mothers’ education, women’s empowerment, facilitating institutional delivery and media accessibility are critical to promoting health-seeking behaviors among mothers or caregivers of under-five children with ARI symptoms. Hence, concerned bodies should design targeted interventions that increase mothers’ or caregivers’ treatment-seeking behavior for childhood ARI to reduce child morbidity and mortality.
