Prevalence of medically induced psychological trauma and its influence on women's health.

The aim of the present study was three-fold. One, to assess the prevalence of medical traumatization in outpatients of a gynecologic department; two, to analyze the relationship of medical traumatization with adverse childhood events; and three, to investigate the extent to which medical traumatization affects the health outcomes of woman. Between January and September 2022, a prospective cross-sectional study recruited patients of a gynecologic outpatient clinic at St. Gallen Cantonal Hospital in Switzerland. Medical trauma was a self-reported item. The presence of adverse childhood events was assessed using the Childhood Trauma Questionnaire. The severity of post-traumatic stress was evaluated using the Impact of Event Scale Revised questionnaire. In total, 227 patients were recruited. Medical trauma was reported by 20% of the interviewees and it was strongly associated with obesity (A= 0.005). Undergoing surgery was most commonly the source of psychological distress (5.7%) followed by delivery (4.8%), pregnancy loss (4.8%), and cancer diagnosis (4.0%). Yet, fewer than 1% of the patients reached the threshold suggesting post-traumatic stress disorder. We found no relationship between the medical trauma, adverse childhood events, cardiovascular disease, or substance abuse. The presence of medical trauma was associated with the patient's body mass index (calculated as weight in kilograms divided by the square of height in meters).

Effect of body tissue composition on the outcome of patients with metastatic non-small cell lung cancer treated with PD-1/PD-L1 inhibitors.

Obesity and sarcopenia have been reported to affect outcomes in patients with non-small cell lung cancer (NSCLC) treated with immune checkpoint inhibitors (ICIs). We analyzed prospective data from 52 patients with non-oncogene driven metastatic NSCLC treated with ICIs. Body tissue composition was calculated by measuring the fat and muscle densities at the level of 3rd lumbar vertebra in each patient computed tomography scan before ICI initiation using sliceOmatic tomovision. We converted the densities to indices [Intramuscular Fat Index (IMFI), Visceral Fat Index (VFI), Subcutaneous Fat Index (SFI), Lumbar Skeletal Muscle Index (LSMI)] by dividing them by height in meters squared. Patients were dichotomized based on their baseline IMFI, VFI and SFI according to their gender-specific median value. The cut-offs that were set for LMSI values were 55 cm2/m2 for males and 39 cm2/m2 for females. SFI distribution was significantly higher (p = 0.040) in responders compared to non-responders. None of the other variables affected response rates. Low LSMI HR: 2.90 (95% CI: 1.261-6.667, p = 0.012) and low SFI: 2.20 (95% CI: 1.114-4.333, p = 0.023) values predicted for inferior OS. VFI and IMFI values did not affect survival. Subcutaneous adipose and skeletal muscle tissue composition significantly affected immunotherapy outcomes in our cohort.

Prevalence of anemia and its predictors among patients with chronic kidney disease admitted to a teaching hospital in Ethiopia: A hospital-based cross-sectional study.

Anemia is a common complication of chronic kidney disease (CKD) and is associated with adverse patient outcomes. However, data on the prevalence of anemia in CKD patients is sparse, particularly in resource-limited settings. Therefore, this study aimed to assess the prevalence of anemia and its predictors among patients with CKD admitted to the Jimma medical center, southwest Ethiopia. A hospital-based prospective cross-sectional study was conducted from September 1 to November 30, 2020. All adult patients with CKD aged ≥18 years who fulfilled the inclusion criteria were consecutively recruited into the study. Data were entered into the Epi data manager version 4.4.1 and then exported to SPSS version 22 (IBM Corp., Armonk, NY) for analysis. The predictors of anemia were determined using multivariable logistic regression analysis. Statistical significance was set at P < .05. A total of 150 patients were included in this study. Of these, 64.67% were male, 56.67% had stage 5 CKD, 78% had a CKD duration of less than 1 year, and 74% had proteinuria. Hypertension (40.7%) and diabetes (14.7%) were the common causes of CKD. The prevalence of anemia was 85.33%. Of the patients, 28.67%, 40.67%, and 16% had mild, moderate, and severe anemia, respectively. On multivariate logistic regression, stage 4 CKD (adjusted odds ratio [AOR] 3.2, confidence interval [CI]: 1.78-12.91, P = .025), stage 5 CKD (AOR 4.03, CI: 1.17-13.73, P = .016), and CKD duration of less than 1 year (AOR 3, CI: 1.19-9.11, P = .007) were significantly associated with anemia. The prevalence of anemia among stage 3 to 5 CKD patients was very high. Anemia was significantly associated with the severity and duration of CKD. Therefore, serial follow-up of patients with a long duration and advanced stages of CKD may help prevent anemia and its adverse consequences.

Association of Physical Activity and Screen Time With Body Mass Index Among US Adolescents

The Physical Activity Guidelines Advisory Committee Scientific Report identified important research gaps to inform future guidance for adolescents, including limited evidence on the importance of sedentary behaviors (screen time) and their interactions with physical activity for adolescent health outcomes, including overweight and obesity. To identify the independent associations of physical activity and screen time categories, and the interactions between physical activity and screen time categories, with body mass index (BMI) and overweight and obesity in adolescents. This cross-sectional study used data from the Adolescent Brain Cognitive Development (ABCD) Study collected from September 10, 2018, to September 29, 2020. Data were analyzed from July 8 to December 20, 2022. A total of 5797 adolescents aged 10 to 14 years from 21 racially and ethnically diverse study sites across the US were included in the analysis. Categories of total step count per day (with 1000 to 6000 steps per day indicating low, >6000 to 12 000 steps per day indicating medium, and >12 000 steps per day indicating high), as measured by a wearable digital device (Fitbit), and categories of self-reported screen time hours per day (with 0 to 4 hours per day indicating low, >4 to 8 hours per day indicating medium, and >8 hours per day indicating high). Participant BMI was calculated as weight in kilograms divided by height in meters squared and converted into sex- and age-specific percentiles in accordance with the Centers for Disease Control and Prevention growth curves and definitions. Individuals were classified as having overweight or obesity if their BMI was in the 85th percentile or higher for sex and age. Among 5797 adolescents included in the analytic sample, 50.4% were male, 61.0% were White, 35.0% had overweight or obesity, and the mean (SD) age was 12.0 (0.6) years. Mean (SD) reported screen time use was 6.5 (5.4) hours per day, and mean (SD) overall step count was 9246.6 (3111.3) steps per day. In models including both screen time and step count, medium (risk ratio [RR], 1.24; 95% CI, 1.12-1.37) and high (RR, 1.29; 95% CI, 1.16-1.44) screen time categories were associated with higher overweight or obesity risk compared with the low screen time category. Medium (RR, 1.19; 95% CI, 1.06-1.35) and low (RR, 1.30; 95% CI, 1.11-1.51) step count categories were associated with higher overweight or obesity risk compared with the high step count category. Evidence of effect modification between screen time and step count was observed for BMI percentile. For instance, among adolescents with low screen use, medium step count was associated with a 1.55 higher BMI percentile, and low step count was associated with a 7.48 higher BMI percentile. However, among those with high screen use, step count categories did not significantly change the association with higher BMI percentile (low step count: 8.79 higher BMI percentile; medium step count: 8.76 higher BMI percentile; high step count: 8.26 higher BMI percentile). In this cross-sectional study, a combination of low screen time and high step count was associated with lower BMI percentile in adolescents. These results suggest that high step count may not offset higher overweight or obesity risk for adolescents with high screen time, and low screen time may not offset higher overweight or obesity risk for adolescents with low step count. These findings addressed several research gaps identified by the Physical Activity Guidelines Advisory Committee Scientific Report and may be used to inform future screen time and physical activity guidance for adolescents.

Longitudinal association between adiposity changes and lung function deterioration

BackgroundThe longitudinal relationship between adiposity and lung function is controversial. We aimed to investigate the long-term association between adiposity changes and lung function in a middle-aged general Asian population.MethodsIn total, 5011 participants (average age, 54 years; 45% men) were enrolled from a community-based prospective cohort. During the follow-up period (median 8 years), both spirometry and bio-electrical impedance analysis were performed biannually. Individual slopes of the fat mass index (FMI; fat mass divided by the square of height in meters) and waist-to-hip ratio (WHR) were calculated using linear regression analysis. Multivariate linear mixed regression analysis was used to determine the long-term association between adiposity changes and lung function.ResultsThe FMI was inversely associated with forced vital capacity (FVC) (estimated: − 31.8 mL in men, − 27.8 mL in women) and forced expiratory volume in 1 s (FEV1) (estimated: − 38.2 mL in men, − 17.8 mL in women) after adjusting for baseline age, height, residential area, smoking exposure (pack-years, men only), initial adiposity indices, and baseline lung function. The WHR was also inversely associated with FVC (estimated = − 1242.2 mL) and FEV1 (estimated = − 849.8 mL) in men. The WHR-increased group showed a more rapid decline in lung function than the WHR-decreased group in both the fat-gain and fat-loss groups.ConclusionAdiposity was associated with the long-term impairment of lung function. Central obesity was the main driver of lung function impairment in the middle-aged general Asian population, regardless of fat mass changes.

Adherence to Healthy Lifestyle Prior to Infection and Risk of Post–COVID-19 Condition

Few modifiable risk factors for post-COVID-19 condition (PCC) have been identified. To investigate the association between healthy lifestyle factors prior to SARS-CoV-2 infection and risk of PCC. In this prospective cohort study, 32 249 women in the Nurses' Health Study II cohort reported preinfection lifestyle habits in 2015 and 2017. Healthy lifestyle factors included healthy body mass index (BMI, 18.5-24.9; calculated as weight in kilograms divided by height in meters squared), never smoking, at least 150 minutes per week of moderate to vigorous physical activity, moderate alcohol intake (5 to 15 g/d), high diet quality (upper 40% of Alternate Healthy Eating Index-2010 score), and adequate sleep (7 to 9 h/d). SARS-CoV-2 infection (confirmed by test) and PCC (at least 4 weeks of symptoms) were self-reported on 7 periodic surveys administered from April 2020 to November 2021. Among participants with SARS-CoV-2 infection, the relative risk (RR) of PCC in association with the number of healthy lifestyle factors (0 to 6) was estimated using Poisson regression and adjusting for demographic factors and comorbidities. A total of 1981 women with a positive SARS-CoV-2 test over 19 months of follow-up were documented. Among those participants, mean age was 64.7 years (SD, 4.6; range, 55-75); 97.4% (n = 1929) were White; and 42.8% (n = 848) were active health care workers. Among these, 871 (44.0%) developed PCC. Healthy lifestyle was associated with lower risk of PCC in a dose-dependent manner. Compared with women without any healthy lifestyle factors, those with 5 to 6 had 49% lower risk (RR, 0.51; 95% CI, 0.33-0.78) of PCC. In a model mutually adjusted for all lifestyle factors, BMI and sleep were independently associated with risk of PCC (BMI, 18.5-24.9 vs others, RR, 0.85; 95% CI, 0.73-1.00, P = .046; sleep, 7-9 h/d vs others, RR, 0.83; 95% CI, 0.72-0.95, P = .008). If these associations were causal, 36.0% of PCC cases would have been prevented if all participants had 5 to 6 healthy lifestyle factors (population attributable risk percentage, 36.0%; 95% CI, 14.1%-52.7%). Results were comparable when PCC was defined as symptoms of at least 2-month duration or having ongoing symptoms at the time of PCC assessment. In this prospective cohort study, pre-infection healthy lifestyle was associated with a substantially lower risk of PCC. Future research should investigate whether lifestyle interventions may reduce risk of developing PCC or mitigate symptoms among individuals with PCC or possibly other postinfection syndromes.

Effect of Pretransplant Sarcopenia on Mortality in Liver Transplant Recipients

Sarcopenia is an important metabolic disorder associated with end-stage liver disease and is an independent predictor of mortality in liver transplant candidates. We evaluated effects of pretransplant muscle mass, muscle quality, and visceral adipose tissue on mortality after liver transplant. For 2015-2020, we included 65 liver transplant recipients whose records contained pretransplant liver computed tomography images. We calculated skeletal muscle mass index (muscle tissue area in centimeters squared divided by height in meters squared), visceral-to-subcutaneous fat ratio (visceral adiposity indicator), and intramuscular adipose tissue content ratio (muscle quality indicator). Median age was 55 years (IQR, 45-63 years), and 48 (73.8%) patients were men. During follow-up, 53 (81.5%) study group patients survived; mean survival time was 71.73 ± 3.81 months. The deceased patient group had a statistically higher pretransplant visceral-to-subcutaneous fat ratio than the survival group (P = .046). Survival was 100% for 1 positive indicator, 86.2% for 2 positive indicators, and 70.4% for 3 positive indicators (P = .096). Positive correlation was confirmed between pretransplant skeletal muscle mass index and age (P = .043) and pretransplant body mass index (weight in kilograms divided by height in meters squared) (P < .001). There was a moderate positive correlation between pretransplant intramuscular adipose tissue content ratio and age (R = 0.529, P ≤ .001) and a weak positive correlation with pretransplant body mass index (R = 0.361, P = .003). Furthermore, pretransplant visceral- tosubcutaneous fat ratio showed a weak positive correlation with age (R = 0.306, P = .013) and a weak negative correlation with the Model for End-Stage Liver Disease score (R = -0.301, P = .016). Pretransplant sarcopenia is an important indicator to predict mortality and morbidity in posttransplant follow-up. Visceral-to-subcutaneous fat ratio is an important parameter to evaluate sarcopenia in liver transplant patients.

Evaluation of the Oestrogenic Activity of Cassia sieberiana Root Bark (Calsepinaceae)

Cassia sieberiana is a tree of 8 to 10 meters in height, used to treat various diseases including malaria, dysmenorrhea and many others. Our objective is the scientific valorisation of Cassia sieberiana, a plant used in therapy in the Ivory Coast, through the evaluation of the estrogenic activity of the root bark of Cassia sieberiana. To do this, the phytochemical study was carried out in order to determine the main chemical constituents with therapeutic potential, then the acute toxicity by gavage was carried out and finally the estrogenic activity was verified. The phytochemical study revealed the presence of sterols, polyterpenes, polyphenols, flavonoids, catechic tannins, saponosides and alkaloids. As for the toxicity study, it allowed us to determine a per os LD50 &gt; 5000 mg/kg PC. The aqueous extract of the root bark of Cassia sieberiana has an estrogenic activity.

From basalt to biosphere: Early non-vent community succession on the erupting Vailulu’u deep seamount

Volcanic eruptions provide rare opportunities to witness the biological recolonization of areas covered by new lava flows by effectively resetting the ecological succession clock to zero. The role of submarine volcanic eruptions as disturbance events and the resulting patterns of ecological succession have mainly been studied in hydrothermal vent ecosystems. However, the effects of submarine volcanic eruptions as disturbance forces have rarely been studied in non-vent ecosystems, particularly on seamounts. Here, we document the early stages of ecological succession of non-vent benthic communities inhabiting the summit caldera of the active Vailulu’u submarine volcano in American Samoa. Sitting above the Samoan volcanic hotspot, Vailulu’u is the youngest volcano of the Samoan chain. Repeated mapping of Vailulu’u in 1999, 2005, 2006, 2012, and 2017 revealed the progressive growth of a new cone named Nafanua. In 18 years, the cone grew &amp;gt;300 meters in height from a starting depth of ~1000 meters below sea level (mbsl). The differential analyses of this time-series bathymetry dataset enabled the assignment of maximum age ranges to different portions of the new cone. High-definition ROV imagery collected in 2017 revealed patterns of community structuring consistent with ecological succession: newly erupted seafloor contained a subset of the benthic species found on older seafloor. Furthermore, individual animal sizes in the younger seafloor zones were smaller than in the older zones. This unusual interdisciplinary combination of geological and biological observations provides constraints on which deep-sea animals recolonize new seafloor after a major disturbance event and how quickly. This knowledge could be applied to identify signs and states of recovery from anthropogenic disturbances by a deep seamount ecosystem.

Association of Carotid Atherosclerosis With Hearing Loss

To describe the association between midlife carotid atherosclerosis and late-life hearing loss among participants in the Atherosclerosis Risk in Communities (ARIC) study. For this cross-sectional study and temporal analysis of a cohort within the ongoing ARIC prospective cohort study, participants were recruited from 4 communities in the US. The analysis evaluated information on mean carotid intima-media thickness (cIMT), from visit 1 (1987-1989) to visit 4 (1994-1996), carotid plaque presence at visit 4, and audiometric data from visit 6 (2016-2017). The cIMT measures were calculated from ultrasonography recordings by trained readers at the ARIC Ultrasound Reading Center. At each visit, cIMT was computed as the average of 3 segments: the distal common carotid, the carotid artery bifurcation, and the proximal internal carotid arteries. Presence of carotid plaque was determined based on an abnormal wall thickness, shape, or wall texture. Audiometric 4-frequency pure tone average (PTA) was measured and calculated for the better-hearing ear and modeled as a continuous variable. Linear regression estimated the association between cIMT and carotid plaque with hearing, adjusting for age, sex, race and study center, education level, body mass index (calculated as weight in kilograms divided by height in meters squared), smoking status, hypertension, cholesterol levels, diabetes, and exposure to occupational noise. Missing data (exposure and covariates) were imputed with multiple imputation by chained equations. Data analyses were performed from April 6 to July 13, 2022. Hearing loss assessed using 4-frequency (0.5, 1.0, 2.0, and 4.0 kilohertz) PTA for both ears and carotid plaque at visit 4 and mean cIMT from visit 1 to visit 4. Among a total of 3594 participants (mean [SD] age at visit 4, 59.4 [4.6] years; 2146 [59.7%] female; 819 [22.8%] Black and 2775 [77.2%] White individuals), fully adjusted models indicated that an additional 0.1 mm higher mean cIMT was associated with 0.59 dB (95% CI, 0.17 to 1.02 dB) higher PTA. Compared with participants without carotid plaque, plaque presence was associated with 0.63 dB (95% CI, -0.57 to 1.84 dB) higher PTA. The findings of this cross-sectional study with temporal analyses of a cohort with the ongoing ARIC study found that subclinical atherosclerosis in midlife was associated with worse hearing in older adulthood. Prevention and control of carotid atherosclerosis during middle age may positively affect the hearing health of older adults.

The importance of the soap tree plant (Kelreiteria Paniculata) in environmental protection and landscaping in the climatic conditions of the Namangan region

Soapwood grows in countries with a warm climate, but northern India is the main area of its location. Sapindus is a tree with 5-10 pairs of leaves, somewhat reminiscent of our mountain flower. The tree can grow up to 25 meters in height and has beautiful green-white flowers. After that, beautiful fruits appear, similar to nuts in the shell. Then they are used instead of soap and shampoo, because they contain 40 percent of saponin. It is this substance that actively removes dirt from any fabric and surface.

PS-P11-6: ESTABLISHING A RELATINSHIP BETWEEN BMI AND HYPERTENSION IN UNIVERSITY STUDENTS

Introduction: The Body Mass Index (BMI) has been identified as a key predictor of Blood Pressure (B.P). Objective The goal of the study is to discover the pattern of relationship between BMI and blood pressure in 1000 university students. Materials and methods: Blood pressure, weight, and height were all taken into account. The BMI was computed by dividing the weight in kilogrammes by the height in metres squared (kg/m). Results: Females were underweight in greater numbers than males (8.4% versus 4.7%). Males were more overweight than females (9% versus 5%). Males were more likely than females to be obese (7% versus 0.9%). Blood pressure parameters increased significantly with BMI (p0.0001), with higher values in males than females; (the mean systolic blood pressure 125.8 ± 8.3mmHg in males versus 117 ± 5.8mmhg in females and the mean diastolic blood pressure 94.6 ± 6.8mmhg in males versus 71 ± 7.7 in females) (p &lt; 0.05). Conclusion: Among university students, a strong link between BMI and blood pressure was observed. Higher blood pressures were observed with higher BMI.

Impact of COVID-19-related lockdown on metabolic syndrome variables in healthcare workers with pre-existing metabolic syndrome: A prospective study

Background: An extraordinary impact on health-care personnel has been caused by the coronavirus disease-2019 (COVID-19) pandemic, a health-care crisis. Aims and Objectives: Our aim was to assess the effects of a changing lifestyle on anthropometric measurements, blood glucose levels, atherogenic lipid profiles, and blood pressure over the course of a year in Indian healthcare workers (HCWs). Materials and Methods: A prospective study was carried out on 40 HCWs including 23 male and 17 females between the age of 22 and 59 years. The study was conducted in the Department of Physiology and the Department of Biochemistry, Government Medical College, Kathua, UT of Jammu and Kashmir. Informed written consent was obtained from the subjects and ethical clearance was obtained from the Institutional Ethics Committee. Height, weight, waist circumference, and systolic and diastolic blood pressure were measured using standard methods. Body mass index was calculated as weight in kilograms divided by the square of height in meters. Results: The present study found statistically significant increase in systolic blood pressure and statistically significant decrease in mean HDL-cholesterol before and after COVID-19 pandemic in HCWs. Conclusion: The onset of metabolic syndrome and its potential effects could be stopped by early use of preventative interventions in the changed parameters.

Korelacija indeksa telesne mase sa refraktivnim greškama

Background. Body mass index (BMI) is a person's weight in kilograms (or pounds) divided by the square of height in meters (or feet). Obesity affects a wide spectrum of age groups, from the young to the elderly, and there are several eye diseases related to obesity like diabetic retinopathy, floppy eyelid syndrome, retinal vein occlusion, stroke-related vision loss, age-related macular degeneration, and possibly, refractive errors. Refractive errors (RE) are optical imperfections related to the focusing ability of the eye and are the main cause of visual impairment which may result in missed education and employment opportunities, lower productivity and impaired quality of life. Aim. The study aimed to find an association between body mass index (BMI) and refractive errors. Methodology. A cross-sectional study was designed to involve a representative sample of medical students in Al-Kindy College of medicine, from December 8, 2021 to January 10, 2022. Weight and height were measured. BMI was estimated, and their refractive error was assessed. Results. A total of 400 students participated in the study, of which 191 (47.8%) had refractive errors, whereas 209 (52.2%) were emmetropic. Thirty-seven point eight percent of the participants had BMI &gt; 25. A significant relationship between refractive errors and all BMI groups was found (p &lt; 0.025). Compared to normal weight group, overweight and obese groups, only the underweight group showed a significant relationship with refractive errors, p &lt; 0.006. Conclusion. Myopia is associated with being underweight, hence the link between the two is statistically significant. The severity of this condition, however, is unaffected by body mass index. Myopia was not a concern among students with normal or high body mass index (BMI).

Wave distribution and proposed seawall design around Tanjung Emas Port, Semarang

On May 23rd, 2022, an extreme coastal event occurred around the northern coast of Java. This event had caused the collapsed of several seawall segments around Tanjung Emas Port, Semarang. Combined with wave overtopping, it led to severe flooding and economic damages to the port operation. Responding to the event, this research aimed to characterize the hydrodynamic condition around the port and proposed a seawall design. The research was done through field observation, wave climate characterization, and numerical simulation. The field observation confirmed the extent of the damage and wave condition around the harbour. The wave climate study, based on a global wave reanalysis data, confirmed that the offshore wave height could reach 3 m during high wave season, with wave period of 4 – 6 seconds coming from the northwest. The tidal range is up to 1 m with highest astronomical tide (HAT) is at +0.65 MSL. The extreme value analysis gave a 3.7 meter of offshore design wave height for 100-year return period or up to 1.7 meters wave height nearshore. The proposed seawall crest elevation is at least at +3.40 meters above the mean sea level to avoid overtopping, which is 1.1 m higher than the existing seawall.

BMI and clinical consequences of untreated dental caries in 3 to 6 years old children

Dental caries and their consequences are known to impact the oral health related quality of life in children. Considering the relationship between refined carbohydrates and odontogenic infections, it is hypothesized that nutritional status and oral health are closely associated. The present study was undertaken to assess the relationship of body mass index (BMI) and odontogenic diseases. Sample consisted of 260 children (3-6 year-old).Dental Caries status assessed using WHO criteria (1997) and prevalence of clinical consequences of dental caries was assessed using PUFA/pufa scale (2010) . Anthropometric measurements assessed included; height measured in meters using height chart and weight in kilograms using portable weighing scale. The BMI (Body Mass Index) was calculated using formula Weight (Kg) ÷Height (meter). The results of our study showed no statistically significant relationship between body mass index (BMI) with either dmft/ dmfs or pufa.

Anti-Inflammatory Activity of Aqueous Extract of Stem Bark of Cassia Sieberiana (Caesalpiniaceae)

Cassia sieberiana is a tree of 8 to 10 meters in height, used to treat various diseases including malaria, dysmenorrhea and many others. Our objective is the scientific valorisation of Cassia sieberiana, a plant used in therapy in Ivory Coast, by evaluating the anti-inflammatory activity of the bark of the root of Cassia sieberiana. To do this, the phytochemical study was carried out in order to determine the main chemical constituents with therapeutic potential, then the acute toxicity by gavage and intraperitoneal injection were carried out and finally the anti-inflammatory activity was verified. The phytochemical study revealed the presence of sterols, polyterpenes, polyphenols, flavonoids, catechic tannins, saponosides and alkaloids. As for the toxicity study, it allowed us to determine by per os route an LD50 &gt; 5000 mg/kg PC, and by IP an LD50 = 524, 807 mg/kg PC graphically and by calculation an LD50 = 400 mg/kg PC. The anti-inflammatory activity of the aqueous extract of Cassia sieberiana at a dose of 200 mg/kg CP is higher than that of diclofenac at a dose of 10 mg/kg CP from the 3rd to the 6th hour of the experiment. Cassia sieberiana is non-toxic by oral administration but toxic by intraperitoneal injection. Cassia sieberiana also has anti-inflammatory activity.

Investigation of the relationship between body mass index and early childhood caries

Aim: The aim of this study is to determine the relationship between body mass index (BMI) and early childhood caries by using the decayed, missing, and filled teeth (DMFT) index in early childhood. Methodology: The sample of the study consisted of 133 children, 63 boys and 70 girls, aged 2–6 years, Dental scans of the children were performed by two experienced physicians in line with World Health Organization criteria, using mirrors and probes, in daylight. The DMFT index was employed to determine the number of DMFT. The height and weight of the children were measured and recorded with a digital scale and height ruler during the examination. BMI was calculated by dividing their body weight (kg) by the square of their height in meters. Results: There was no statistically significant difference between age groups according to gender (p &gt; 0.05). When the DMFT index values according to the BMI classifications of the children participating in the study and the number of caries, missing, and filled teeth of four different groups (weak, normal, overweight, obese) were compared according to the BMI classification, a difference was observed between the groups. The DMFT indexes of the children who were evaluated as obese with an increasing BMI had higher results than those for the other groups (p &lt; 0.05). Conclusion: More detailed and long-term studies are needed to determine the causal relationship between the variables examined when evaluating the relationship between dental caries and BMI, as well as to formulate appropriate interventions related to these variables.

Effect of Preoperative Right Ventricular Dysfunction on Heart Transplantation Outcomes

We investigated if the occurrence of preoperative right ventricular dysfunction is capable of influencing heart transplant results in terms of in-hospital mortality, incidence of primary graft dysfunction, and follow-up mortality. We retrospectively analyzed 517 patients who underwent heart transplant between January 2000 and December 2020. We defined right ventricular dysfunction (RVD), as central venous pressure (CVP) > 15 mm Hg and CVP/pulmonary capillary wedge pressure ratio > 0.63. We identified 2 subgroups in our population: 33 patients with preoperative RVD and 484 patients without RVD. In-hospital mortality was 7.9%. Severe early graft failure occurred in 6.6% of patients, with 26 patients (5.1%) needing intra-aortic balloon pump and 17 patients (3.3%) needing extracorporeal membrane oxygenation support. Clinical variables that significantly influenced in-hospital mortality were age, peripheral artery disease, and bilirubin > 1.5 mg/dL, while hemodynamic variables influencing in-hospital mortality were CVP (odds ratio [OR], 1.09 [confidence interval {CI}, 1.03-1.15], P=.004], pulmonary artery systolic pressure (OR, 1.02 [CI, 1.00-1.04], P=.05), CVP/pulmonary capillary wedge pressure ratio (OR, 2.78 [CI, 1.14-6.80], P=.025), pulmonary vascular resistance (OR, 1.15 [CI, 1.01-1.32], P=.042), transpulmonary gradient (TPG) (OR, 1.11 [CI, 1.03-1.18], P=.003) , diastolic transpulmonary gradient (OR, 1.10 [CI, 1.02-1.20], P=.015], together with right ventricular dysfunction (OR, 3.56 [CI, 1.44-8.80], P=.011). On the other hand, clinical variables influencing the incidence of early graft failure were body mass index (calculated as weight in kilograms divided by height in meters squared) > 30, peripheral artery disease, bilirubin > 1.5 mg/dL, Model for End-Stage Liver Disease score excluding international normalized ratio before transplant, and preoperative extracorporeal membrane oxygenation support, while hemodynamic variables were pulmonary arterial systolic pressure (OR, 1.03 [CI, 1.00-1.05], P=.016), TPG (OR, 1.08 [1.01-1.17], P=.03), and right ventricular dysfunction (OR, 3.00 [CI, 1.07-8.40] P=.046). On the multivariable analysis, RVD and TPG were independent predictors of in-hospital mortality, while only TPG was a predictor of early graft failure. Follow-up mortality was 38.7% and was influenced by recipient age, recipient body mass index, and preoperative diabetes. Moreover, 1-, 5-, and 10-year survival of patients with preoperative RVD was significantly worse than patients without RVD (log-rank=0.001). In our population, RVD influenced both in-hospital and long-term results after heart transplant. For these reasons, it appears crucially important to optimize preoperative right ventricular function to improve these patients' outcomes.

Associations of Neighborhood Opportunity and Social Vulnerability With Trajectories of Childhood Body Mass Index and Obesity Among US Children

Physical and social neighborhood attributes may have implications for children's growth and development patterns. The extent to which these attributes are associated with body mass index (BMI) trajectories and obesity risk from childhood to adolescence remains understudied. To examine associations of neighborhood-level measures of opportunity and social vulnerability with trajectories of BMI and obesity risk from birth to adolescence. This cohort study used data from 54 cohorts (20 677 children) participating in the Environmental Influences on Child Health Outcomes (ECHO) program from January 1, 1995, to January 1, 2022. Participant inclusion required at least 1 geocoded residential address and anthropometric measure (taken at the same time or after the address date) from birth through adolescence. Data were analyzed from February 1 to June 30, 2022. Census tract-level Child Opportunity Index (COI) and Social Vulnerability Index (SVI) linked to geocoded residential addresses at birth and in infancy (age range, 0.5-1.5 years), early childhood (age range, 2.0-4.8 years), and mid-childhood (age range, 5.0-9.8 years). BMI (calculated as weight in kilograms divided by length [if aged <2 years] or height in meters squared) and obesity (age- and sex-specific BMI ≥95th percentile). Based on nationwide distributions of the COI and SVI, Census tract rankings were grouped into 5 categories: very low (<20th percentile), low (20th percentile to <40th percentile), moderate (40th percentile to <60th percentile), high (60th percentile to <80th percentile), or very high (≥80th percentile) opportunity (COI) or vulnerability (SVI). Among 20 677 children, 10 747 (52.0%) were male; 12 463 of 20 105 (62.0%) were White, and 16 036 of 20 333 (78.9%) were non-Hispanic. (Some data for race and ethnicity were missing.) Overall, 29.9% of children in the ECHO program resided in areas with the most advantageous characteristics. For example, at birth, 26.7% of children lived in areas with very high COI, and 25.3% lived in areas with very low SVI; in mid-childhood, 30.6% lived in areas with very high COI and 28.4% lived in areas with very low SVI. Linear mixed-effects models revealed that at every life stage, children who resided in areas with higher COI (vs very low COI) had lower mean BMI trajectories and lower risk of obesity from childhood to adolescence, independent of family sociodemographic and prenatal characteristics. For example, among children with obesity at age 10 years, the risk ratio was 0.21 (95% CI, 0.12-0.34) for very high COI at birth, 0.31 (95% CI, 0.20-0.51) for high COI at birth, 0.46 (95% CI, 0.28-0.74) for moderate COI at birth, and 0.53 (95% CI, 0.32-0.86) for low COI at birth. Similar patterns of findings were observed for children who resided in areas with lower SVI (vs very high SVI). For example, among children with obesity at age 10 years, the risk ratio was 0.17 (95% CI, 0.10-0.30) for very low SVI at birth, 0.20 (95% CI, 0.11-0.35) for low SVI at birth, 0.42 (95% CI, 0.24-0.75) for moderate SVI at birth, and 0.43 (95% CI, 0.24-0.76) for high SVI at birth. For both indices, effect estimates for mean BMI difference and obesity risk were larger at an older age of outcome measurement. In addition, exposure to COI or SVI at birth was associated with the most substantial difference in subsequent mean BMI and risk of obesity compared with exposure at later life stages. In this cohort study, residing in higher-opportunity and lower-vulnerability neighborhoods in early life, especially at birth, was associated with a lower mean BMI trajectory and a lower risk of obesity from childhood to adolescence. Future research should clarify whether initiatives or policies that alter specific components of neighborhood environment would be beneficial in preventing excess weight in children.
