Endophenotypes of Primary Osteoarthritis of the Hip Joint in the Bulgarian Population over 60 Years Old.

Aim. To identify subgroups of patients with primary osteoarthritis of the hip joint (pHOA) with similar imaging and laboratory findings, disease evolution, and response to conventional therapies. Methods. We performed further statistical analyses on patient data from two published, double-blind, randomized, and placebo-controlled studies (DB-RCTs), which examined the effects of intra-articular corticosteroids (ia-CSs), hyaluronic acid (ia-HA)-KИ-109-3-0008/14.01.2014, and intravenous bisphosphonates (iv-BPs) -KИ- 109-3-0009/14.01.2014 compared to the country's standard pHOA therapy. The data span an 8-year follow-up of 700 patients with pHOA, including: 1. Clinical parameters (WOMAC-A, B, C, and T; PtGA). 2. Laboratory markers (serum calcium and phosphate levels; 25-OH-D and PTH, markers for bone sCTX-I and cartilage uCTX-II turnover). 3. Radiological indicators: X-ray stage (Kellgren-Lawrence (K/L) and model (Bombelli/OOARSI), width (mJSW), speed (JSN mm/year), and zone of maximum narrowing of the joint space (max-JSN)-determining the type of femoral head migration (FHM). 4. DXA indicators: bone geometry (HAL; NSA; and MNW); changes in regional and total bone mineral density (TH-BMD, LS-BMD, and TB-BMD). 5. Therapeutic responses (OARSI/MCII; mJSW; JSNmm/yearly) to different drug regimens (iv-BP -zoledronic acid (ZA/-5 mg/yearly for 3 years)); ia-CS 40 mg methylprednisolone acetate, twice every 6 months; and ia-HA with intermediate molecular weight (20 mg/2 mL × 3 weekly applications, two courses every 6 months) were compared to standard of care therapy (Standard of Care/SC/), namely D3-supplementation according to serum levels (20-120 ng/mL; target level of 60 ng/mL), simple analgesics (paracetamol, up to 2.0 g/24 h), and physical exercises. The abovementioned data were integrated into a non-supervised hierarchical agglomerative clustering analysis (NHACA) using Ward's linkage method and the squared Euclidean distance to identify different endophenotypes (EFs). Univariate and multivariate multinomial logistic regression analyses were performed to determine the impact of sex and FHM on clinical and radiographic regression of pHOA. Results. A baseline cluster analysis using incoming (M0) patient data identified three EFs: hypertrophic H-HOA, atrophic A-HOA, and intermediate I-HOA. These EFs had characteristics that were similar to those of patients grouped by radiographic stage and pattern ('H'-RPs, 'I'-RPs, and 'A'-RPs), p < 0.05). The repeated cluster analysis of M36 data identified four EF pHOAs: 1. Hypertrophic (slow progressors, the influence of the type of femoral head migration (FHM) outweighing the influence of sex on progression), progressing to planned total hip replacement (THR) within 5 (K/LIII) to 10 (K/LII) years. 2. Intermediate (sex is more important than the FHM type for progression) with two subgroups: 2#: male-associated (slow progressors), THR within 4 (K/LIII) to 8 years. (K/LII). 2* Female-associated (rapid progressors), THR within 3 (K/LIII) to 5 (K/LII) years. 3. Atrophic (rapid progressors; the influence of FHM type outweighs that of sex), THR within 2 (K/LIII) to 4 (K/LII) years. Each EF, in addition to the patient's individual progression rate, was also associated with a different response to the aforementioned therapies. Conclusions. Clinical endophenotyping provides guidance for a personalized approach in patients with pHOA, simultaneously assisting the creation of homogeneous patient groups necessary for conducting modern genetic and therapeutic scientific studies.

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.

Association between tuberculosis and psychotic experiences: Mediating factors and implications for patient care in low- and middle-income countries.

Tuberculosis may play a role in the aetiology of psychosis. However, little is known about the association between tuberculosis and psychotic experiences (PEs) or the mediating factors of this association. We analysed cross-sectional data from 48 low- and middle-income countries of the World Health Survey (WHS). Tuberculosis assessment was based on past 12-month symptoms of active tuberculosis. We assessed four types of past 12-month PEs with the Composite International Diagnostic Interview. We performed multivariable multinomial logistic regression and mediation analysis. We analysed data on 224 842 individuals aged ≥18 years (mean age = 38.3 years, standard deviation = 16.0; 50.7% women). Tuberculosis was associated with 1.84 (95% confidence interval (CI) = 1.41-2.40), 2.18 (95%CI = 1.58-3.03), and 3.79 (95%CI = 2.88-4.98) times higher odds for 1, 2, and ≥3 PEs, respectively. The mediation analysis showed that the association between tuberculosis and at least one PE is mainly explained by anxiety (31.5%), sleep/energy (27.8%), and pain/discomfort (23.5%). Tuberculosis was associated with increased odds of PEs. Factors such as affect, sleep, and pain should be considered in tuberculosis patients to target those who might be particularly vulnerable to PEs, and consequently, to psychotic disorders and other adverse effects of PE.

Cesarean sections and sociodemographic disparities in Ecuador: A nationwide study from hospital registries between 2015 and 2022.

This study aimed to analyze sociodemographic factors associated with cesarean sections (c-sections) in Ecuador. Data were extracted from the Ecuadorian National Institute of Statistics and Censuses (INEC). Multivariate binary and multinomial logistic regression analyses were performed to assess sociodemographic factors associated with c-sections overall and with each type of c-section (elective or emergency c-section). This study included 1 118 842 in-hospital deliveries during 2015-2022 in Ecuador, of which 41.3% were c-sections. This exceeds the recommended levels of medical justified c-sections. Those who were older than 20-29 years showed a higher probability for c-sections overall. Regarding ethnicity, Montubios had 57% higher probability for c-sectioned with an adjusted odds ratio (aOR) of 1.57 and a 95% confidence interval (CI) of 1.45-1.71; while indigenous, black, and white individuals exhibited 73%, 29%, and 21% lower probabilities, respectively. However, this varied according to specific type of c-sections: black individuals had 11% higher probability of elective c-section but 44% lower probability of emergency c-section. Deliveries in private healthcare facilities exhibited significantly higher probabilities of c-sections overall (aOR 15.38, 95% CI 15.20-15.56). Higher probability of emergency c-section was also observed during 2020-2022. Cesarean sections in Ecuador still exceed the recommended levels of medically justified c-sections, highlighting the importance of adopting an approach to childbirth that reduces unnecessary interventions. These results suggest an important role of sociodemographic factors, which aligns with the reported need for multicomponent and locally tailored strategies for addressing c-section overuse. The increase in c-sections during the COVID-19 pandemic (2020-2022) might suggest the influence of external health crises on maternal healthcare.

Late Neonatal Sepsis in Very-low-birth-weight Premature Newborns Is Associated With Alterations in Neurodevelopment at Twenty-five Months of Age.

To evaluate the impact of late-onset sepsis (LOS) on the neurodevelopment of very-low-birth-weight (VLBW) premature infants. This is a retrospective cohort study of VLBW premature infants. The Mental Development Index (MDI) was determined for a population of 546 VLBW infants, at 14 and 25 months of age, and evaluated using the Bayley test. A history of meningitis or early neonatal sepsis was considered an exclusion criterion. The study parameters analyzed included perinatal variables, the development of neonatal comorbidities and a history of LOS. Multivariate linear regression and multinomial logistic regression analyses were performed. LOS was observed in 115 newborns, among whom microbiological testing showed that 65.0% presented Gram-positive bacteria, with Staphylococcus epidermidis being responsible for 55.4%. There was a significant association between the 25-month MDI and a history of LOS. This represents a decrease of 7.9 points in the MDI evaluation of newborns with a history of LOS. The latter history is also associated with the following neurodevelopmental alternations: mild motor disorders [odds ratio (OR): 2.75; 95% confidence intervals (CI): 1.07-7.05], moderate cognitive delay (OR: 3.07; 95% CI: 1.17-8.00) and cerebral palsy (OR: 2.41; 95% CI: 1.09-5.35). In our study cohort, LOS was associated with alterations in neurodevelopment, including reduced MDI, together with motor and cognitive disorders and cerebral palsy. To improve neurodevelopmental outcomes in this group of newborns, neonatal intensive care unit personnel should focus attention on preventing hospital-acquired infections.

Do HER2-Low Tumors Have a Distinct Clinicopathologic Phenotype?

Breast cancer subtypes, distinguished by hormone receptor (HR) and HER2 status, have different clinicopathologic features. With recognition of the clinical relevance of HER2-low, there is debate as to whether this is a distinct subtype. Our study aimed to determine whether HER2-low breast cancers have specific clinicopathologic features that differ from those of HER2-negative and HER2-positive cancers. A total of 11,072 patients undergoing upfront surgery from 1998 to 2010 were identified from a single-institution prospectively maintained database. HER2 status was classified by immunohistochemistry (IHC)/fluorescence in situ hybridization (FISH) as HER2 negative (41.2%), HER2 low (45%; IHC 1+ or 2+ with negative FISH), and HER2 positive (13.7%), and stratified by HR status. Univariate (UVA) and multivariable multinomial logistic regression analysis (MVA) were performed to determine associations among variables and subtypes. Compared with HER2-negative tumors, HER2 low was associated with lymphovascular invasion [odds ratio (OR) 1.2, 95% confidence interval (CI) 1.06-1.36; p = 0.003], multifocality (OR 1.26, 95% CI 1.12-1.42; p < 0.001), nodal micrometastasis (OR 1.15, 95% CI 1.02-1.31; p = 0.024), and lower rates of ≥ 3 positive nodes (OR 0.77, 95% CI 0.66-0.90, p = 0.001). When stratified by HR expression, in both HR-positive and HR-negative tumors, age and multifocality were associated with HER2 low on UVA. On MVA, no variables were independently associated with both HR-negative and HR-positive/HER2-low tumors compared with HER2-negative tumors. In contrast, HER2-positive tumors, regardless of HR status, were associated with multifocality and an extensive intraductal component. Clinicopathologic features of HER2-low tumors appear to be primarily related to HR status. Our findings do not support the characterization of HER2 low as a separate subtype.

Geospatial analysis and participant characteristics associated with colorectal cancer screening participation in Alberta, Canada: a population-based cross-sectional study

BackgroundColorectal cancer (CRC) is a leading cause of death in Canada and early detection can prevent deaths through screening. However, CRC screening in Alberta, Canada remains suboptimal and varies by sociodemographic and health system characteristics, as well as geographic location. This study aimed to further the understanding of these participant and health system characteristics associated with CRC screening in Alberta and identify clusters of regions with higher rates of overdue or unscreened individuals.MethodsWe included Albertans aged 52 to 74 as of December 31, 2019 (index date) and we used data from administrative health data sources and linked to the Alberta Colorectal Cancer Screening Program database to determine colorectal cancer screening rates. We used multivariable multinomial logistic regression analysis to investigate the relationship between sociodemographic, health system characteristics and participation in CRC screening. We used optimized Getis-Ord Gi* hot-spot analysis to identify hot and cold-spots in overdue for and no record of CRC screening.ResultsWe included 919,939 Albertans, of which 65% were currently up to date on their CRC screening, 21% were overdue, and 14% had no record of CRC screening. Compared to Albertans who were currently up to date, those who were in older age groups, those without a usual provider of care, those who were health system non-users, and those living in more deprived areas were more likely to have no record of screening. Areas with high number of Albertans with no record of screening were concentrated in the North and Central zones.ConclusionsOur study showed important variation in colorectal cancer screening participation across sociodemographic, health system and geographical characteristics and identified areas with higher proportions of individuals who have no record of screening or are under-screened in Alberta, Canada.

Do Determinants of Smoking Cessation and Relapse Differ between Men and Women? Data from a French National Study

Introduction: There is limited understanding of different predictors of smoking cessation success (SCS) among women and men, despite well-documented differences in smoking behavior. Methods: Using data from DePICT (Description des Perceptions, Images, et Comportements liés au Tabagisme), a national survey of French adults which recruited 2377 regular and former smokers we investigated whether major determinants of SCS differed by sex. Factors associated with unsuccessful vs. No successful quit attempt; vs. SCS were studied using multivariate multinomial logistic regression analyses stratified by sex. Results: Women and men share some determinants of SCS including no cannabis use, living in a nonsmoker household and importance giving to being a nonsmoker. However, no e-cigarette use, low-to-moderate alcohol consumption, early smoking initiation, and higher education were associated with SCS only among women. No use of nicotine replacement, having family members who smoke, family opinion on smoking and current employment, were associated with SCS only among men. Neutral or negative friends’ opinion on smoking or living with a smoker were associated with unsuccessful smoking attempts among men. Conclusions: Our results show differences between determinants of SCS according to sex, which highlights the importance of developing tailored interventions that account for sex/gender differences in smoking cessation.

Women empowerment domains and unmet need for contraception among married and cohabiting fecund women in Sub-Saharan Africa: A multilevel analysis based on gender role framework.

Low women empowerment, is a known contributing factor to unmet needs for contraception by limiting access to health services through negative cultural beliefs and practices. However, little is known about the association between unmet needs and domains of women empowerment in Sub-Saharan African (SSA) countries. Hence, this study aimed at assessing the influence of women empowerment domains on the unmet need for contraception in the region using the most recent Demographic and Health Survey (DHS) data (2016-2021). The data for the study was derived from the appended women's (IR) file of eighteen SSA countries. A weighted sample of 128,939 married women was analyzed by STATA version 16. The Harvard Institute's Gender Roles Framework, which comprised of influencer, resource, and decision-making domains was employed to identify and categorize the covariates across three levels. The effects of each predictor on the unmet need for spacing and limiting were examined using a multivariable multilevel mixed-effect multinomial logistic regression analysis. Adjusted relative risk ratio (aRRR) with its corresponding 95% confidence interval was used to declare the statistical significance of the independent variables. The pooled prevalence of unmet needs for contraception was 26.36% (95% CI: 24.83-30.40) in the region, with unmet needs for spacing and limiting being 16.74% (95% CI: 16.55, 17.02) and 9.62% (95% CI: 9.45, 12.78), respectively. Among variables in the influencer domain, educational level, family size of more than five, parity, number of children, attitude towards wife beating, and media exposure were substantially linked with an unmet need for spacing and limiting. Being in the poorest wealth quintile and enrollment in health insurance schemes, on the other hand, were the two variables in the resource domain that had a significant influence on unmet needs. The overall decision-making capacity of women was found to be the sole significant predictor of unmet needs among the covariates in the decision-making domain. Unmet needs for contraception in SSA countries were found to be high. Reproductive health program planners and contraceptive service providers should place due emphasis on women who lack formal education, are from low-income families, and have large family sizes. Governments should collaborate with insurance providers to increase health insurance coverage alongside incorporating family planning within the service package to minimize out-of-pocket costs. NGOs, government bodies, and program planners should collaborate across sectors to pool resources, advocate for policies, share best practices, and coordinate initiatives to maximize the capacity of women's decision-making autonomy.

Caregiver burden and its associated factors among primary caregivers of stroke survivors at Amhara regional state tertiary hospitals: a multicenter study

BackgroundCaregivers of stroke survivors play a crucial role in post-stroke functional recovery and the prevention of complications. Although the situation is incredibly stressful and intimidating and the caregiver burden is high, there is little evidence in the local Ethiopian context of the extent of the burden among caregivers of stroke survivors. Therefore, the aim of this study was to assess the level of caregiver burden and its associated factors among primary caregivers of stroke survivors in Ethiopia.MethodsA cross-sectional study was conducted in Amhara regional state tertiary hospitals from April to June 2022. A standardized questionnaire was used to record factors associated with caregiver burden, including sociodemographic, clinical, and care situation factors. The Zarit caregiver burden interview (short form) was used to assess the level of caregiver burden. A systematic random sampling method was employed to select the study participants. Multinomial logistic regression was employed to identify the potential factors associated with the level of caregiver burden.ResultsThe overall prevalence burden among primary caregivers of stroke survivors was 67%. 61.1% had a mild to moderate burden, while 5.9% had a severe burden. In multivariable multinomial logistic regression analysis, sex, household income, duration of care, and duration of caregiving hours per day were factors significantly associated with the level of burden among caregivers of stroke survivors.ConclusionsBeing female, having a low household income, caring for more than 3 months, and caring for more than 6 h per day were factors significantly associated with the burdens of the primary caregivers of stroke survivors. It is better: health care providers must recognize and screen for burdens and provide special attention.

Anti-N-methyl-D-aspartate receptor encephalitis in adults: asystematic review and analysis.

To analyze predictors of treatment outcome for anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis in adults. We performed acomprehensive literature search of PubMed, PsycInfo, and OVID. We included 424patients from case reports and case series. Demographics, anti-NMDAR antibodies, prodromal and presenting symptoms, diagnostic workup, and treatment variables were recorded. Inferential analyses were performed in the subset (n = 299) of those with known treatment outcomes. Multivariate multinomial logistic regression analysis for treatment outcome compared full recovery versus partial recovery and full recovery versus death. Treatment outcomes consisted of 34.67% full recovery (n = 147), 30.90% partial recovery (n = 131), 4.95% death (n = 21), and 29.48% unknown (n = 125). Speech/language abnormality and abnormal electroencephalogram (EEG) were each significantly associated with ahigher relative risk for afull recovery. Treatment with intravenous immunoglobulin and plasmapheresis were each significantly associated with ahigher relative risk for partial recovery. The analysis comparing death to full recovery found that catatonia was significantly associated with alower relative risk for death. Increased age, orofacial dyskinesia, and no tumor removal were each significantly associated with ahigher relative risk for death. Increased age, orofacial dyskinesia, and no tumor removal were associated with ahigher relative risk for death in anti-NMDAR encephalitis in adults. Clinicians should monitor and appropriately treat anti-NMDAR encephalitis with these findings to minimize the risk of death.

Differences in Demographic and Clinical Characteristics Among Subtypes of Female Pattern Hair Loss.

Female pattern hair loss (FPHL) is the most common hair loss disorder in women that can be classified into three patterns, including Ludwig, Olsen, and Hamilton-Norwood subtypes. Information regarding the comparison of demographics, clinical characteristics, and associated comorbidities among subtypes of FPHL is scarce and contradictory. To evaluate and compare the epidemiology, clinical manifestations, and comorbid conditions of FPHL subtypes and determine their associated factors. This retrospective study included patients who were diagnosed with FPHL between January 2000 and November 2021. Participants were classified into three subtypes, namely Ludwig, Olsen, and Hamilton-Norwood, and were statistically compared. Variables significantly associated with each FPHL subtype were identified using multivariable multinomial logistic regression analysis. Among the 519 patients with FPHL, the Ludwig subtype was the most prevalent (51.1%), followed by the Olsen (32.9%) and Hamilton-Norwood (16%) subtypes. The Hamilton-Norwood subtype revealed significantly higher frequencies of early disease onset (61.4%), menstrual irregularity (22.9%), polycystic ovary syndrome (PCOS, 18.1%), and seborrhea (30.1%) but lower frequencies of overweight (24.1%) and type 2 diabetes mellitus (DM, 2.4%). Multivariable multinomial regression analysis demonstrated that the Hamilton-Norwood subtype was a predictor for early disease onset and PCOS compared to Ludwig (early onset: odds ratio (OR) = 2.14, 95% confidence interval (CI) = 1.39-4.22, P = 0.02; PCOS: OR = 2.02, 95% CI = 1.55-4.84, P = 0.03), and Olsen (early onset: OR = 1.89, 95% CI = 1.03-3.92, P = 0.04; PCOS: OR = 2.24, 95% CI = 1.89-5.31, P = 0.01). In contrast, the Hamilton-Norwood pattern was at decreased risk for type 2 DM compared to Ludwig (OR = 0.51, 95% CI = 0.03-0.82, P = 0.02), and Olsen (OR = 0.68, 95% CI = 0.04-0.79, P = 0.03). The Ludwig pattern was found to be the most prevalent FPHL subtype among Thai patients. Moreover, the Hamilton-Norwood subtype was associated with early disease onset and PCOS, whereas the Ludwig and Olsen subtypes were associated with type 2 DM.

Assessing the influence of digital technologies on antenatal care visits in Zimbabwe: insights from 2019 Zimbabwe Multiple Indicator Cluster Survey

Background and objectiveTo provide good health and well-being as established by the Sustainable Development Goal (SDG) 3, access to digital technologies can act as conduits to achieve such progress in a population. As guided by the World Health Organization, antenatal care (ANC) attendance is one of the measures promoted to curtail the global health burden of maternal and infant mortality. ANC services are seldom utilized to their full potential in Zimbabwe. This study explores if any of the women's digital technology characteristics were associated with antenatal care visits. MethodsThe study analyzed population-based cross-sectional data with a subsample of 1 932 women aged 15‒49 years from the 2019 Zimbabwe Multiple Indicator Cluster Survey. Test of associations with chi-square test, bivariate, and multivariate multinomial logistic regression analyses were used to examine the predictors of adequate (4‒7) and optimal (≥ 8) ANC visits relative to undesirable (1‒3) antenatal care visits among women who had given births 2 years before the survey. ResultsThe results indicate that 64.5% (1246/1 932) of the women attained adequate ANC while about 9.8% (189/1 932) attained optimal ANC. Reading a newspaper/magazine at least once a week (odds ratio [OR] 1.73, β’ = 0.551, t = 2.030, P = 0.043) and watching television at least once a week (OR 1.72, β’ = 0.545, t = 2.454, P = 0.015), listening to the radio less than once a week (OR 1.28, β’ = 0.247, t = 1.750, P = 0.080), and owning a mobile phone (OR 1.48, β’ = 0.394, t = 3.020, P = 0.003) were positively associated with adequate ANC. Optimal ANC was significantly associated with women being able to read a newspaper at least once a week (OR 2.93, β’ = 1.074, t = 3.120, P = 0.002), listen to the radio less than once a week (OR 2.07, β’ = 0.73, t = 2.700, P = 0.007) and have ownership of a mobile phone (OR 1.88, β’ = 0.631, t = 2.620, P = 0.009). ConclusionAccess to a newspaper, radio, television, and mobile phone were important predictors of a woman's ability to achieve her ANC attendance. Policies to improve the knowledge of ANC packages can be facilitated using digital technology to achieve adequate and preferably optimal ANC in Zimbabwe. It is important to improve digital infrastructure to support digital technologies in providing ANC services.

Adverse Childhood Experiences and Tobacco Use among Latinx Parents in the USA.

The current study aimed to understand the effects of adverse childhood experiences (ACEs) and cultural factors on Latinx parents' tobacco use. Tobacco use is the leading cause of death among Latinx individuals in the USA, and parental use has long-term secondary harm for children. Thus, it is important to examine cultural protective factors that could prevent Latinx parents and children from the negative health effects of tobacco use. Data came from 2813 18- to 50-year-old Latinx respondents who participated in the Wave 3 of the National Epidemiological Survey on Alcohol and Related Conditions. They reported having children living in their household and had complete data for the variables of interest. In this sample (mean age = 33.5years, 53.7% female), 16.4% (95%CI = 14.7%, 18.4%) and 7.4% (95%CI = 6.4%, 8.6%) were current and former smokers, respectively. The multivariate multinomial logistic regression analysis showed that experiencing more ACEs categories was associated with increased likelihood of current and former tobacco use compared to never use. Past year discrimination experiences and being US born (2nd and 3rd-generation parents) also increased the likelihood of current use. Differences in risk of current and former tobacco use were found based on respondents' country of origin, with protection against tobacco use found for most countries compared to being from Puerto Rico. Stronger ethnic-racial identity was not protective against tobacco use. Findings show the importance of considering ACEs and cultural factors when designing and implementing tobacco cessation programs for Latinx parents and increasing awareness of the impact of parents' tobacco use on their children.

Association between sarcopenia and frailty in elderly patients with chronic kidney disease.

Frailty and sarcopenia are prevalent in chronic kidney disease (CKD) populations and could increase the risk for adverse health outcomes. Few studies assess the correlation between frailty, sarcopenia and CKD in non-dialysis patients. Therefore, this study aimed to determine frailty-associated factors in elderly CKD stage I-IV patients, expected to early identify and intervene in the frailty of elderly CKD patients. A total of 774 elderly CKD I-IV patients (>60years of age) recruited from 29 clinical centers in China between March 2017 and September 2019 were included in this study. We established a Frailty Index (FI) model to evaluate frailty risk and verified the distributional property of FI in the study population. Sarcopenia was defined according to the criteria of the Asian Working Group for Sarcopenia 2019. Multinomial logistic regression analysis was used to assess the associated factors for frailty. Seven hundred seventy-four patients (median age 67years, 66.0% males) were included in this analysis, with a median estimated glomerular filtration rate of 52.8mL/min/1.73m2 . The prevalence of sarcopenia was 30.6%. The FI exhibited a right-skewed distribution. The age-related slope of FI was 1.4% per year on a logarithmic scale (r2 =0.706, 95% CI 0.9, 1.8, P<0.001). The upper limit of FI was around 0.43. The FI was related to mortality (HR=1.06, 95% CI 1.00, 1.12, P=0.041). Multivariate multinomial logistic regression analysis showed that sarcopenia, advanced age, CKD stage II-IV, low level of serum albumin and increased waist-hip ratio were significantly associated with high FI status, while advanced age and CKD stage III-IV were significantly associated with for median FI status. Moreover, the results from the subgroup were consistent with the leading results. Sarcopenia was independently associated with an increased risk for frailty in elderly CKD I-IV patients. Patients with sarcopenia, advanced age, high CKD stage, high waist-hip ratio and low serum albumin level should be assessed for frailty.

Do HER2 low tumors have a distinct clinicopathologic phenotype?

570 Background: Clinicopathologic features of breast cancer subtypes defined by hormone receptor (HR) and HER2 status differ. These analyses classified HER2 IHC &lt;3+ with negative FISH as HER2-. With the recognition of the clinical relevance of HER2 low, there is debate as to whether this is a distinct subtype. We sought to determine if features of HER2 low tumors differ from HER2- and HER2+ after controlling for HR status. Methods: Patients undergoing upfront surgery from 1998 to 2010 were identified from a prospectively maintained institutional database. HER2 status was classified by IHC/FISH analysis as HER2-, HER2 low (IHC 1+ or 2+ with negative FISH), and HER2+ (IHC 3+ or FISH +) and stratified by HR status. Univariable (UVA) and multivariable multinomial logistic regression analysis (MVA) were performed to determine associations among variables and subtypes. Results: 11,323 tumors from 11,072 patients were included. 5,104 (45%) were HER2 low, 41.2% were HER2- and 13.6% were HER2+. On MVA stratified by HER2 status only, compared to HER2- tumors, HER2 low was associated with LVI (OR 1.2 [95% CI 1.06-1.36]; p=.003), multifocality (OR 1.26 [95% CI, 1.12-1.42]; p&lt;.001), nodal micrometastasis (OR 1.15 [95% CI, 1.02-1.31]; p=.024), and lower rates of &lt;3 positive nodes (OR 0.77 [95% CI, 0.66-0.90], p=.001). HER2+ was associated with younger age, high grade, multifocality, extensive intraductal component (EIC), and pN2/3 nodal stage. Clinicopathologic features stratified by HR and HER2 status are shown in the table. On UVA, in both HR+ and HR– tumors, age and multifocality were associated with HER2 low, and LVI, multifocality, and EIC with HER2+ compared to HER2- tumors. On MVA, no variables were independently associated with both HR+ and HR-/HER2 low tumors compared to HER2-. In contrast, HER2+ tumors regardless of HR status were significantly associated with multifocality and EIC. Conclusions: HER2 low breast cancer features seem to be driven by HR status and HER2 overexpression. We do not have enough evidence to support the interpretation of HER2 low as a distinct subtype.

Risk factors, comorbidity and social impairment of ICD-11 PTSD and complex PTSD in Danish treatment-seeking military veterans

PurposeWhile a number of studies have investigated risk factors and comorbidities of ICD-11 post-traumatic stress disorder (PTSD) and complex PTSD (CPTSD) in various trauma exposed samples, few studies have been conducted in military samples. Existing studies with military samples have included rather small samples. The aim of the present study was to identify risk factors and comorbidities of ICD-11 PTSD and CPTSD in a large sample of previously deployed, treatment-seeking soldiers and veterans. Methods: Previously deployed, treatment-seeking Danish soldiers and veterans (N = 599), recruited from the Military Psychology Department of the Danish Defense, completed the International Trauma Questionnaire (ITQ), as well as questionnaires of common mental health difficulties, trauma exposure, functioning and demographics. Multivariate multinomial logistic regression analysis explored differences in self-reported exposure to adversity and health outcomes between those meeting ICD-11 criteria for probable PTSD, CPTSD and no trauma disorder. Results: A total of 13.0% met probable ICD-11 criteria for PTSD and 31.4% for CPTSD. Risk factors for CPTSD (compared to those with no trauma disorder) included exposure to warfare or combat, longer duration since the traumatic event and being single. Those with CPTSD were more likely than those with PTSD or no trauma disorder to endorse symptoms of depression, anxiety, stress, use of psychotropic medication, and suicide attempts. Conclusion: CPTSD is a more common and debilitating condition compared to PTSD in treatment-seeking soldiers and veterans. Further research should focus on testing existing and novel interventions for CPTSD in the military.

Prenatal Dietary Patterns and Associations With Weight-Related Pregnancy Outcomes in Hispanic Women With Low Incomes.

Background: Dietary patterns during pregnancy may contribute to gestational weight gain (GWG) and birthweight, but there is limited research studying these associations in racial and ethnic minority groups. The objective of this study was to evaluate associations between prenatal dietary patterns and measures of GWG and birthweight in a cohort of culturally diverse Hispanic women with low incomes. Methods: Data were analyzed from 500 mother-infant dyads enrolled in the Starting Early Program, a childhood obesity prevention trial. Diet over the previous year was assessed in the third trimester of pregnancy using an interviewer-administered food frequency questionnaire. Dietary patterns were constructed using the Healthy Eating Index-2015 (HEI-2015) and principal components analysis (PCA) and analyzed as tertiles. GWG and birthweight outcomes were abstracted from medical records. Associations between dietary pattern tertiles and outcomes were assessed by multivariable linear and multinomial logistic regression analyses. Results: Dietary patterns were not associated with measures of GWG or adequacy for gestational age. Greater adherence to the HEI-2015 and a PCA-derived dietary pattern characterized by nutrient-dense foods were associated with higher birthweight z-scores [β: 0.2; 95% confidence interval (CI): 0.04 to 0.4 and β: 0.3; 95% CI: 0.1 to 0.5, respectively], but in sex-specific analyses, these associations were only evident in male infants (β: 0.4; 95% CI: 0.03 to 0.7 and β: 0.3; 95% CI: 0.03 to 0.6, respectively). Conclusions: Among a cohort of culturally diverse Hispanic women, adherence to healthy dietary patterns during pregnancy was modestly positively associated with increased birthweight, with sex-specific associations evident only in male infants.

The Association Between Pre-Pregnancy Body Mass Index and Gestational Weight Gain on Pregnancy Outcomes: A Retrospective Cohort Study

Introduction: Elevated pre-gestational body mass index (obese/overweight) and improper gestational weight gain are important risk factors for predicting adverse pregnancy outcomes. Objective: We aimed to identify the association between pre-pregnancy body mass index (BMI) and gestational weight gain on birth outcomes. Materials and Methods: Data from this retrospective cohort study were extracted from 1457 (out of 1800) pair health records belonging to the pregnant mother and infants at Ahvaz Iran health care centers from 2010 to 2018. Ten public health care centers were randomly selected from the headquarters west and east of Ahvaz City. The samples were selected based on the inclusion criteria. They divided into different groups based on BMI (underweight, normal, overweight, and obese) and gestational weight gain (GWG) groups (inadequate and excessive versus adequate). Pregnancy outcome was analyzed according to the GWG during pregnancy for each BMI group through multivariable multinomial logistic regression. Relationships between maternal BMI, GWG, and offspring weight were examined. The analysis of covariance (ANCOVA) was used with adjusting the baseline values. The risks for adverse birth weight outcomes in women with different pre-pregnancy BMIs and GWGs were tested using the multivariable multinomial logistic regression analysis. Results: The Mean±SD of maternal age was 28.36±5.60 years. The Mean±SD birth weight was 3271.37±486.57 g. About 4.5%, 89.3%, and 6.2% of newborns were low birth weight, normal weight, and macrosomia, respectively. Also, 46.4% of women had weight gain above the guidelines. The increased risk for large for gestational age in overweight mothers (odds ratio [OR] =3.18, 95%CI; 0.45-7.29, P=0.007) and an increased risk for small for gestational age in those mothers with gestational weight gain below the guidelines (OR=2.9, 95%CI; 1.16- 7.45, P=0.02). An increased risk of large for gestational age, low birth weight, and macrosomia were observed in overweight mothers with gestational weight gain out of the guidelines. An increased association was found between the maternal pre-pregnancy BMI and fasting blood sugar in 24 to 28 weeks of gestation. Hence, hyperglycemia is related to the incidence of macrosomia (OR=3.58, 95%CI; 1.70-7.66, P=0.0001). Conclusion: Managing maternal weight with respect to reproductive health care is required for all women in childbearing age (before and during pregnancy) to reduce the adverse pregnancy outcome.
