RESUMO
INTRODUCTION: Patients with pectus excavatum (PE) often undergo cross-sectional imaging (CSI) to quantify severity for insurance authorization before surgical repair. The modified percent depth (MPD), an external caliper-based metric, was previously validated to be similar to the pectus index and correction index. This study explored family perceptions of CSI and MPD with respect to value and costs. METHODS: This is a cross-sectional survey study including families of patients enrolled in an ongoing prospective multicenter study evaluating the use of MPD as an alternative to CSI for quantifying PE severity. Families of PE patients who underwent both MPD and CSI completed a survey to determine their perceptions of MPD and costs of CSI. Responses were described and associations were evaluated using chi squared, Wilcoxon rank-sum test and logistic regression as appropriate. Statistical significance was set to 0.05. RESULTS: There were 136 surveys completed for a response rate of 88%. Respondents were confident in MPD (86%) and confident in its similarity to CSI (76%). Families of females were less confident in the measurements than males (55% versus 80%, P = 0.02; odds ratio 0.30 (0.11, 0.83). Obtaining CSI required time off work/school in 90% and a copay in 60%. Nearly half (49%) of respondents reported CSI was a time/financial hardship. Increasing copay led to decreased reassurance in CSI (55%: copay > $100 versus 77%: lower copay/75%: no copay; P = 0.04). CONCLUSIONS: From the family perspective, MPD is valuable in assessing the severity of PE. Obtaining CSI was financially burdensome, particularly for those with higher copays. MPD measurements provide high value at low cost in assessing the severity of PE.
RESUMO
BACKGROUND: Care home staff are key providers of palliative and end-of-life care. Yet, little is known about how care home characteristics can influence care leader's confidence in their ability to provide optimal palliative and end-of-life care. AIM: To understand the influence of care home registration type (nursing, residential or dual registered) and size on senior care leader's confidence to provide palliative and end-of-life care. DESIGN: An explanatory sequential mixed methods study comprising an online cross-sectional survey (including the Palliative Care Self-Efficacy Scale) and qualitative individual interviews. Analysis of survey data used a multivariate logistic regression and qualitative interview data used Framework Analysis. A 'Following the Thread' method was undertaken for data integration. SETTING/PARTICIPANTS: UK care home senior care leaders, purposively sampled by registration type, size and geographical location. RESULTS: The online survey (N = 107) results indicated that nursing home senior care leaders had higher confidence scores on the Palliative Care Self-Efficacy Scale than residential care home leaders (aOR: 3.85, 95% CI 1.20-12.31, p = 0.02). Care home size did not show effect when adjusting for registration type (medium - aOR 1.71, 95% CI 0.59-4.97, p = 0.33; large - aOR 0.65, 95% CI 0.18-2.30, p = 0.5). Interviews (n = 27) identified three themes that promote confidence, (1) 'feelings of preparedness' stemming from staff expertise and experience and care home infrastructure, (2) 'partnership working' with external services as a valued member of the multidisciplinary team, and (3) a shared language developed from end-of-life care guidance. CONCLUSION: Care home senior care leader's confidence is influenced by care home characteristics, particularly availability of on-site registered nurses and the infrastructure of large care homes. All care home leaders benefit from training, working with external, multidisciplinary teams and use of guidance. However, mechanisms to achieve this differed by care home type and size. Further exploration is needed on successful integration of palliative care services and interventions to enhance confidence in residential care homes.

PURPOSE: Benign prostatic hyperplasia (BPH) commonly impacts the quality of life in older men. However, there is lack of research on relationship between dietary niacin intake and the risk of BPH. The purpose of this study was to investigate the relationship between dietary niacin intake and the risk of BPH. METHODS: Data from the NHANES spanning 2003 to 2008 were utilized. BPH was determined using a self-report questionnaire, while dietary niacin intake was calculated based on the mean of two distinct diet interviews. Multivariate logistic regressions were performed to explore the association, supplemented with restricted cubic splines and subgroup analysis. RESULTS: A total of 700 males were enrolled, of which 653 men had BPH. After adjusting for all covariates, a high dietary intake of niacin was associated with an increased risk of BPH (OR: 1.04; 95%CI: 1.01-1.07). Furthermore, when the lowest dietary niacin intake is used as the reference, the highest tertile is associated with an increased risk of BPH (OR: 2.34, 95% CI: 1.24-4,42). Restricted cubic splines demonstrated a positive correlation between dietary niacin intake and BPH risk. CONCLUSIONS: The study results demonstrated a positive association between dietary niacin intake and the risk of BPH in elderly men in the US. These findings underscore the importance of systematic assessment before supplementing micronutrients in elderly men.

Background As mobile phones act as a potential source of microbial contamination, particularly in a hospital environment, the effectiveness of two most debated interventions namely ultraviolet radiation and disinfectant wipes in reducing the microbial contamination of mobile phones is compared. Objective To screen the mobile phones of healthcare personnel for the presence of microorganisms and to compare the effectiveness of ultraviolet radiation and disinfectant wipes in reducing microbial contamination. Methods and materials Pre-intervention and post-intervention swabs were collected before and after the use of each intervention respectively using 56 samples and cultured for growth in nutrient agar. Agar plates are subjected to quantitative analysis using bacterial colony count to reflect the efficacy of the specific intervention used. The data collected was entered in Microsoft Excel (Microsoft® Corp., Redmond, WA, USA) and analysis was done using standard statistical packages. Results While comparing the pre-intervention bacterial load with the post-intervention load, post-intervention bacterial contamination in terms of colony-forming units/CFU has drastically reduced after both interventions, which is validated by statistical significance. However, it was observed participants using disinfectant wipes as intervention had 2.07 times higher chance of having a low bacterial load which wasn't statistically significant. Conclusion Our study shows that with the use of any intervention from the above-mentioned interventions, bacterial load or bacterial contamination can be reduced significantly, thus pointing out that both ultraviolet radiation and disinfectant wipes are effective in reducing contamination of mobile phones. It was also found that male doctors have more bacterial load than females, which can be minimized by effectively changing behavioral habits.
RESUMO
Background: In 2019, it was estimated that approximately 1.4 million adults in the United Kingdom purchased illicit cannabis to self-treat chronic physical and mental health conditions. This analysis was conducted following the rescheduling of cannabis-based medicinal products (CBMPs) in the United Kingdom but before the first specialist clinics had started treating patients. Objective: The aim of this study was to assess the prevalence of illicit cannabis consumption to treat a medically diagnosed condition following the introduction of specialist clinics that could prescribe legal CBMPs in the United Kingdom. Methods: Adults older than 18 years in the United Kingdom were invited to participate in a cross-sectional survey through YouGov between September 22 and 29, 2022. A series of questions were asked about respondents' medical diagnoses, illicit cannabis use, the cost of purchasing illicit cannabis per month, and basic demographics. The responding sample was weighted to generate a sample representative of the adult population of the United Kingdom. Modeling of population size was conducted based on an adult (18 years or older) population of 53,369,083 according to 2021 national census data. Results: There were 10,965 respondents to the questionnaire, to which weighting was applied. A total of 5700 (51.98%) respondents indicated that they were affected by a chronic health condition. The most reported condition was anxiety (n=1588, 14.48%). Of those enduring health conditions, 364 (6.38%) purchased illicit cannabis to self-treat health conditions. Based on survey responses, it was modeled that 1,770,627 (95% CI 1,073,791-2,467,001) individuals consume illicit cannabis for health conditions across the United Kingdom. In the multivariable logistic regression, the following were associated with an increased likelihood of reporting illicit cannabis use for health reasons-chronic pain, fibromyalgia, posttraumatic stress disorder, multiple sclerosis, other mental health disorders, male sex, younger age, living in London, being unemployed or not working for other reasons, and working part-time (P<.05). Conclusions: This study highlights the scale of illicit cannabis use for health reasons in the United Kingdom and the potential barriers to accessing legally prescribed CBMPs. This is an important step in developing harm reduction policies to transition these individuals, where appropriate, to CBMPs. Such policies are particularly important considering the potential risks from harmful contaminants of illicit cannabis and self-treating a medical condition without clinical oversight. Moreover, it emphasizes the need for further funding of randomized controlled trials and the use of novel methodologies to determine the efficacy of CBMPs and their use in common chronic conditions.

Few population-based studies including younger adults have examined the potential of olfactory function tests to capture the degree of atrophy in memory-associated brain regions, which cannot be adequately explained by cognitive function tests screening for cognitive impairment. This population-based study investigated associations between high-resolution olfactory test data with few odours and grey matter volumes (GMVs) of the left and right hippocampi, amygdala, parahippocampi, and olfactory cortex, while accounting for differences in cognitive decline, in 1444 participants (aged 31-91 years). Regression analyses included intracranial volume (ICV)-normalised GMVs of eight memory-related regions as objective variables and age, sex, education duration, smoking history, olfaction test score, and the Montreal Cognitive Assessment-Japanese version (MoCA-J) score as explanatory variables. Significant relationships were found between olfactory test scores and ICV-normalised GMVs of the left and right hippocampi and left amygdala (p = 0.020, 0.024, and 0.028, respectively), adjusting for the MoCA-J score. The olfactory test score was significantly related to the right amygdalar GMV (p = 0.020) in older adults (age ≥ 65 years). These associations remained significant after applying Benjamini-Hochberg multiple testing correction (false discovery rate < 0.1). Therefore, olfactory and cognitive function tests may efficiently capture the degree of atrophy in the hippocampi and amygdala, especially in older adults.

Background: Cardiovascular-kidney-metabolic (CKM) health is affected by social determinants of health, especially education. CKM syndrome has not been evaluated in Chinese population, and the association of education with CKM syndrome in different sexes and its intertwined relation with lifestyles have not been explored. Objective: We aimed to explore the association between educational attainment and the prevalence of CKM syndrome stages in middle-aged and older Chinese men and women as well as the potential role of health behavior based on Life's Essential 8 construct. Methods: This study used data from the nationwide, community-based REACTION (Risk Evaluation of Cancers in Chinese diabetic individuals: a longitudinal study). A total of 132,085 participants with complete information to determine CKM syndrome stage and education level were included. Educational attainment was assessed by the self-reported highest educational level achieved by the participants and recategorized as low (elementary school or no formal education) or high (middle school, high school, technical school/college, or above). CKM syndrome was ascertained and classified into 5 stages according to the American Heart Association presidential advisory released in 2023. Results: Among 132,085 participants (mean age 56.95, SD 9.19 years; n=86,675, 65.62% women) included, most had moderate-risk CKM syndrome (stages 1 and 2), and a lower proportion were at higher risk of CKM (stages 3 and 4). Along the CKM continuum, low education was associated with 34% increased odds of moderate-risk CKM syndrome for women (odds ratio 1.36, 95% CI 1.23-1.49) with a significant sex disparity, but was positively correlated with high-risk CKM for both sexes. The association between low education and high-risk CKM was more evident in women with poor health behavior but not in men, which was also interactive with and partly mediated by behavior. Conclusions: Low education was associated with adverse CKM health for both sexes but was especially detrimental to women. Such sex-specific educational disparity was closely correlated with health behavior but could not be completely attenuated by behavior modification. These findings highlight the disadvantage faced by women in CKM health ascribed to low education, underscoring the need for public health support to address this inequality.

This study aimed to assess the relationship between serum levels of vitamin D with anthropometric indices, lipid profile and vascular inflammatory factors, in patients who candidate for coronary artery bypass grafting (CABG). This analytical cross-sectional study was conducted in patients who were candidate for CABG. Demographic information, medical records, anthropometric indicators, blood samples, and physical activity of 150 patients were collected. 146 participants with mean ± standard deviation of age: 61.8 ± 10.0 years and body mass index: 26.9 ± 3.7 kg/m2 completed the study. Based on serum levels of vitamin D, patients were divided into 2 groups; groups with sufficient (≥ 30 ng/mL) and insufficient amount of vitamin D (< 30 ng/mL). The 30.14% of the patients had serum vitamin D deficiency. Ejection fraction (EF) % between the 2 groups had significant difference. Unexpectedly the EF% increased 7% in patients with insufficient level of vitamin D (odds ratio [OR], 1.07; 95% confidence interval [CI], 1.03-1.11; p = 0.001). Vitamin D status had a significant inverse association with body weight. The odds of vitamin D deficiency significantly increased by 4% with increasing one kg in weight (OR, 1.04; 95% CI, 1-1.08; p = 0.044). There were no significant association between serum vitamin D level and intra cellular adhesion molecule-1, interleukin-17, fasting blood glucose, and lipid profile (p > 0.05). Considering the inverse association observed between serum vitamin D with EF% and body weight, vitamin D may play a role in modulating of these indices.
RESUMO
Percutaneous endoscopy of the biliary system (cholangioscopy) and gallbladder (cholecystoscopy) has significantly impacted diagnostic and therapeutic approaches to many diseases in interventional radiology, overcoming previous challenges related to scope size and rigidity. The current endoscopes offer enhanced maneuverability within narrow tubular structures such as bile ducts. Before endoscopy, reliance on 2D imaging modalities limited real-time visualization during percutaneous procedures. Percutaneous endoscopy provides 3D perspectives, enabling a better appreciation of normal structures, targeted biopsy of lesions, and accurate deployment of therapeutic interventions. This review aims to explore percutaneous endoscopic findings across various biliary and gallbladder pathologies.
RESUMO
BACKGROUND: Dental caries remains one of the most prevalent diseases worldwide, affecting 29.4% of the global population. Despite numerous efforts to diagnose, predict, and prevent dental caries, the incidence continues to rise. Salivary biomarkers provide a non-invasive means for early detection of various oral conditions. C-reactive protein (CRP) is a key marker, elevated in both oral and general inflammatory conditions such as diabetes, periodontitis and oral squamous cell carcinoma. Considering the emerging connection between oral and systemic health, it is worth exploring the various factors associated with this widespread disease. This study investigates the association between CRP levels and dental caries in the United States population, utilizing data from the National Health and Nutrition Examination Survey (NHANES). METHODS: The study analyzed data from the 2015-2018 NHANES cycles, focusing on a nationally representative sample of individuals aged 30 years and above. Weighted multivariable negative binomial and logistic regression analyses were employed to explore the relationship between dental caries and CRP levels, adjusting for age, gender, race, education level, diabetes status, and gum disease. RESULTS: The results of the negative binomial regression analysis demonstrated a positive association between higher CRP levels and an increased mean number of dental caries (Adjusted Mean Ratio [AMR] = 1.7; 95% CI: 1.3 - 2; P: < 0.001). The logistic regression analysis showed that individuals with higher CRP levels have a 50% increase in the odds of developing dental caries (AOR: 1.5, CI: 1.2 - 1.9; P: < 0.01). CONCLUSION: The results of this cross-sectional study of the U.S. population highlight the positive association between high CRP levels and increased dental caries. These findings contribute to the growing body of evidence supporting the integration of oral and systemic health care. Further research is necessary to deepen our understanding of the mechanistic relationship between CRP levels and dental caries.

Background: Severe headache or migraine is a neurological disease that seriously affects the quality of human life. Oxidative stress is considered a main factor in the pathogenesis of severe headache or migraine. The Composite Dietary Antioxidant Index (CDAI) is a score calculated using six dietary antioxidant components (including vitamins A, C, E, selenium, zinc, and carotenoid), which represents a person's level of dietary antioxidant ingredients. Based on the theory of oxidative stress, we speculated that CDAIs may be relevant to the risk of severe headache or migraine, as the relationship between the CDAI and severe headache or migraine is unclear. Hence, the purpose of this study was to explore the relationship between the CDAI and severe headache or migraine in participants. Methods: We performed a cross-sectional study using data from the National Health and Nutrition Examination Survey (NHANES) that were collected from 2001 to 2004. A total of 4,943 participants were included, of whom 1,232 experienced severe headaches or migraines. Participants' CDAIs were calculated based on their intake of six dietary antioxidants. We used logistic regression models, limited cubic spline analysis, and subgroup analysis to assess the association of CDAI with severe headache or migraine. Results: The multivariate logistic regression model (correcting for all potential covariates) revealed that the odds ratio (95% Confidence Interval [CI]) for the association between CDAI and severe headache or migraine was 0.97 (95% CI = 0.95-1.00, p = 0.048). Compared with individuals with low CDAIs in Quartile (Q)1, the adjusted Odds Ratio between the CDAI and severe headache or migraine in Q2, Q3, and Q4 were 0.84 (95% CI = 0.69-1.01, p = 0.07), 0.77 (95% CI = 0.63-0.96, p = 0.017), and 0.73 (95% CI = 0.56-0.95, p = 0.02), respectively. Restricted cubic spline regression analysis showed an L-shaped relationship between the CDAI and severe headache or migraine. Conclusion: Our findings indicate that higher CDAI was associated with a lower risk of severe headache or migraine.
RESUMO
PURPOSE: This cross-sectional survey study aimed to explore the phacoemulsification techniques among Swedish cataract surgeons, and investigate the association between technique preferences and surgical outcomes, particularly posterior capsular rupture (PCR). METHODS: A survey questionnaire was responded by 170 cataract surgeons and data from 192 494 cases, linked to the surgeons, were analysed from the Swedish National Cataract Registry (SNCR) for 2021-2022. Surgeons' demographic characteristics, surgical techniques and complications were assessed. Associations between surgical technique preferences and outcomes were analysed with binary logistic regression. RESULTS: The chopping technique (stop and chop or direct chop) was favoured by 64.6% of surgeons, followed by divide and conquer (32.4%), and tilt and tumble (7.6%). Surgeons' annual caseloads varied widely (range 11-2687). No significant correlation was found between technique preference and PCR rates, which was consistently 0.5%-0.6% in all groups, except for a trend suggesting reduced risk with tilt and tumble. Mentoring activity (35.0%) and public surgical setting (40.3%) was highest in the direct chop group. Notably, 75% of the surgeries were performed by surgeons with more than 10 years' experience. Confounding factors, such as high-volume surgeons having a low frequency of complications, have been accounted for in a logistic regression. CONCLUSION: This study provides insights into cataract surgery practices in Sweden and suggests that surgeons can choose their preferred approach without significantly affecting complication rates. This research also underscores the need for continued exploration of surgical practices and their impact on patient outcomes, particularly in the case of the tilt and tumble technique, which is less commonly employed.
RESUMO
Lung cancer is intricately associated with genetic susceptibility, leading to familial clustering among affected individuals. This cross-sectional study aimed to assess the knowledge, attitude, and practice (KAP) toward lung cancer risk among the offspring of lung cancer patients. This study was conducted at Guangdong Provincial People's Hospital between April 2023 and August 2023. Participants' demographic characteristics and KAP toward lung cancer risk were collected through questionnaires. A total of 481 valid questionnaires were enrolled, with 243 (50.52%) males, and 242 (50.31%) aged > 40 years old. The mean scores for knowledge, attitude, and practice were 8.54 ± 2.60 (range: 0-13), 25.93 ± 3.16 (range: 7-35), and 17.47 ± 4.30 (range: 5-25), respectively. Structural equation modeling indicated that knowledge exerted a negative direct effect on attitude (ß = - 0.417, P = 0.006) but a positive direct effect on practice (ß = 0.733, P = 0.025). Additionally, attitudes displayed a negative direct effect on practice (ß = - 1.707, P = 0.002). In conclusion, offspring of lung cancer patients exhibited insufficient knowledge, positive attitude, and suboptimal practice toward lung cancer risk.

Phase IV clinical trials are designed to monitor long-term side effects of medical treatment. For instance, childhood cancer survivors treated with chest radiation and/or anthracycline are often at risk of developing cardiotoxicity during their adulthood. Often the primary focus of a study could be on estimating the cumulative incidence of a particular outcome of interest such as cardiotoxicity. However, it is challenging to evaluate patients continuously and usually, this information is collected through cross-sectional surveys by following patients longitudinally. This leads to interval-censored data since the exact time of the onset of the toxicity is unknown. Rai et al. computed the transition intensity rate using a parametric model and estimated parameters using maximum likelihood approach in an illness-death model. However, such approach may not be suitable if the underlying parametric assumptions do not hold. This manuscript proposes a semi-parametric model, with a logit relationship for the treatment intensities in two groups, to estimate the transition intensity rates within the context of an illness-death model. The estimation of the parameters is done using an EM algorithm with profile likelihood. Results from the simulation studies suggest that the proposed approach is easy to implement and yields comparable results to the parametric model.
RESUMO
Objective: To explore patients' knowledge, attitude, and practice (KAP) toward varicocele in China and the relationship between treatment selection and KAP. Methods: This cross-sectional study enrolled varicocele patients at the Third Affiliated Hospital of Soochow University (September to October 2023). Structural equation modeling (SEM) was used to explore the relationship between clinical factors and KAP. A score >mean score for each dimension was defined as adequate knowledge, positive attitude, and proactive practice. The patients were grouped according to varicocelectomy vs no surgery. Univariable and multivariable logistic regression analyses were used to identify the factors independently associated with KAP. A structural equation modeling (SEM) analysis was performed to examine how the KAP dimensions influenced each other. Results: Among 502 patients, 44.02%, 35.86%, and 20.12% were ≤30, 31-40, and >40 years old, respectively. Those who underwent varicocelectomy (n=407) had significantly higher knowledge (20 (15-22) vs 0 (0-6), P<0.001), attitude (26 (24-26) vs 14 (10-18), P<0.001), and practice (20 (17-24) vs 8 (6-16), P<0.001) than those who did not. A higher proportion of patients with varicocelectomy were <40 years old, more educated, had higher income, and were unmarried compared with those without surgery (all P<0.001). High school or higher education level and varicocelectomy (irrespective of type) were independently associated with adequate knowledge (all P<0.001). Knowledge, college/bachelor's degree education, and varicocelectomy type (irrespective of type) were associated with positive attitudes (all P<0.05). In the SEM, knowledge directly influenced attitude, knowledge directly influenced practice, and attitude directly influenced practice (all P<0.001). Having knowledge of the subject may direct varicocele patients to varicocelectomy. Conclusion: Chinese patients who underwent varicocelectomy exhibit appropriate KAP regarding varicocele, while non-surgery patients have poorer KAP. These results suggest that patients who did not undergo surgery should nevertheless be properly informed about their disease.
RESUMO
BACKGROUND: Endocrine-disrupting chemicals (EDCs) interfere with hormonal systems, potentially causing metabolic, reproductive, and neurological issues, as well as hormone-related cancers. Found in everyday products, EDCs accumulate in body tissues over time, with adverse effects depending on the dose and duration of exposure. This study aims to explore behaviors related to EDC exposure among Saudi citizens to assess the need for further risk reduction interventions. METHODOLOGY: This cross-sectional study employed a validated, self-administered online questionnaire to assess daily life behaviors associated with EDC exposure. A total of 563 participants were recruited using convenient sampling through online platforms. RESULTS: The study revealed that a significant majority of participants were aged 18-25 years (48.67%, n=274). On average, participants scored 32.78 out of a maximum of 60 for potential EDC exposure, with scores ranging from 13 to 54 points. The majority (85.26%, n=480) fell into the moderate potential exposure category, while a small minority (4.26%, n=24) exhibited high potential risk based on their reported daily habits, predominantly among male participants (95.83%, n=23). A significant majority (72.65%, n=409) indicated a likelihood of adopting lifestyle changes to reduce exposure to harmful substances. CONCLUSION: This study reveals diverse behavioral patterns linked to endocrine disruptor exposure among the general population in Saudi Arabia. Interestingly, the participants showed a positive attitude and willingness to change their risky behaviors. These findings underscore the necessity for educational programs and public health campaigns aimed at addressing gaps in knowledge. Encouraging the public to adopt behaviors that reduce exposure is essential to minimizing the potential long-term effects of EDCs.
RESUMO
Background: Mental health issues among middle-aged and older adults are gaining increasing attention. Recent studies have shown that relative grip strength is associated with cardiovascular diseases and various cancers, but its relationship with depression remains unclear. Methods: This cross-sectional study included data from adults aged 50 years and older from the 2011-2014 National Health and Nutrition Examination Survey. Relative grip strength is calculated by dividing the maximum absolute grip strength of both hands by BMI. The Patient Health Questionnaire (PHQ-9) was used to evaluate the depressive outcome. Multivariate logistic regression was performed to assess the association between relative grip strength and depression. Results: In this study, a total of 3,639 participants (≥50 years) with a mean age of 64.3 ± 9.3 years were enrolled, of whom 48.9% were male. Compared with individuals with lower relative handgrip strength in Q1 (≤1.64 kg/BMI), the adjusted OR values for relative handgrip strength and depression in Q2 (1.64-2.17 kg/BMI), Q3 (2.17-2.84 kg/BMI), and Q4 (≥2.84 kg/BMI) were 0.69 (95% CI: 0.51, 0.93, p = 0.016), 0.36 (95% CI: 0.24, 0.55, p < 0.001), and 0.32 (95% CI: 0.20, 0.51, p < 0.001), respectively. The relationship between relative grip strength and depression presented an L-shaped curve (nonlinear, p = 0.006), with an inflection point of roughly 2.98 kg/BMI. Among participants with relative grip strength < 2.98 kg/BMI, the OR of incident depression was 0.41 (95% CI: 0.30-0.55, p < 0.001). Conclusion: Our findings indicated that relative grip strength was inversely associated with incident depression and demonstrated an L-shaped relationship among U.S. middle-aged and older adults. Relative grip strength could be the indicator for future screening of mental health.

OBJECTIVES: Cardiometabolic Index (CMI) is a surrogate marker for metabolic disorders. It is associated with various chronic diseases. This study aims to investigate the relationship between CMI and asthma. METHODS: Data from seven consecutive National Health and Nutrition Examination Survey cycles between 2005 and 2018 were used. The study included adults with self-reported asthma diagnoses and complete information for CMI calculation. The formula for CMI is CMI = [WC (cm)/height (cm)] × [TG (mg/dL)/HDL-C (mg/dL)]. A multivariate logistic regression model was employed to examine the linear relationship between CMI and asthma. Subgroup analyses were conducted to explore potential influencing factors. Additionally, smooth curve fitting and threshold effect analysis were used to describe the non-linear relationship. RESULTS: A higher CMI was possibly associated with an increased prevalence of asthma. After adjusting for various covariates including marital status, Poverty Income Ratio, Body Mass Index, hypertension, diabetes, smoking, alcohol consumption, heart attack, and stroke, the results remained significant (OR = 1.03; 95%CI, 1.00-1.05, p = 0.0178, R2 = 0.52). Participants with the highest CMI had a 38% increased risk of asthma prevalence compared to those with the lowest CMI (OR = 1.38; 95%CI, 1.19-1.60, p < 0.0001). CONCLUSION: The findings reveal that elevated CMI levels correlate with an increased risk of asthma, highlighting CMI's potential as a predictive marker for asthma, particularly in populations with a CMI below 1.97. These results suggest that interventions aimed at improving metabolic health may prove effective in managing or preventing asthma.
RESUMO
Introduction: We aimed to characterize the initial healthcare journey of metastatic pancreatic ductal adenocarcinoma (mPDAC) patients in Portugal, including healthcare provision and factors affecting therapeutic decisions, namely BRCA mutations testing. Methods: This is a descriptive cross-sectional, web-based survey using a convenience sampling approach. Portuguese oncologists and pathologists that routinely work with mPDAC patients from the different geographical regions and settings were invited to participate in the study via email (December 2020). Descriptive statistical analyses were performed, with categorical variables reported as absolute and relative frequencies, and continuous variables with non-normal distribution as median and interquartile range (IQR) (Stata v.15.0). Results: Seventy physicians participated in the study (43 oncologists, 27 pathologists). According to the responses, a median of 28 patients per center (IQR 12-70) was diagnosed with PDAC in the previous year; 22 of them referring (IQR 8-70) to mPDAC. The pointed median time from patients' first hospital admission until disease diagnosis/staging is between 2 and 4 weeks. Endoscopic ultrasound with fine-needle biopsy is available in most hospitals (86%). Around 50% of physicians request BRCA testing; the assessment of additional biomarkers besides BRCA is requested by 40% of professionals. Half of them stated that BRCA testing should be requested earlier-upon histological diagnosis, especially because the median time for results is of 4.0 weeks (IQR 4-8). PARP inhibitors such as olaparib, when available, would be the therapy of choice for most oncologists (71%) if no disease' progression occurs after 4 months. Treatments' selection is usually grounded on clinical criteria (e.g., performance status, liver function). Around 45% of patients use FOLFIRINOX/mFOLFIRINOX as the first-line therapy. Gemcitabine + nab-paclitaxel is used by 35% of patients as the second-line therapy. Conclusions: Physicians in Portugal support the increasing role of patient-tailored treatments in mPDAC, whose selection should be grounded on tumoral subtyping and molecular profiling. Further efforts to develop multidisciplinary teams, standardized clinical practice, and optimize the implementation of new target therapies are needed.
Introdução: Este estudo teve como objetivo caracterizar o percurso inicial dos doentes com adenocarcinoma ductal pancreático metastático (ACDPm) em Portugal, incluindo a prestação de cuidados de saúde e determinação de fatores que afetam as decisões terapêuticas, nomeadamente o teste de mutações BRCA. Métodos: Trata-se de um estudo descritivo transversal (web-based) usando uma abordagem de amostragem por conveniência. Médicos oncologistas e anatomopatologistas portugueses dedicados ao ACDPm e de diferentes regiões geográficas e instituições foram convidados a participar do estudo por email (Dez-2020). Foram realizadas análises estatísticas descritivas, com variáveis categóricas relatadas como frequências absolutas e relativas, e variáveis contínuas com distribuição não-normal como mediana e intervalo interquartil (IIQ) (Stata v.15.0). Resultados: Setenta médicos participaram do estudo (43 oncologistas, 27 patologistas). De acordo com as respostas, uma mediana de 28 doentes por centro (IIQ 1270) foi diagnosticada com ACDP no ano anterior; 22 deles (IIQ 870) referentes a ACDPm. O tempo médio desde a primeira admissão hospitalar dos doentes até o diagnóstico/estadiamento da doença foi entre 24 semanas. A ultrassonografia endoscópica com biópsia por agulha fina é realizada pela maioria dos hospitais (86%). Aproximadamente 50% dos médicos referem solicitar o teste BRCA; a avaliação de biomarcadores adicionais além do BRCA é solicitada por 40% dos profissionais. Metade dos médicos assume que o teste BRCA deveria ser solicitado mais precocemente durante o diagnóstico histológico, principalmente porque o tempo médio para obtenção do resultado é de 4,0 semanas (IIQ 48). Os inibidores PARP, como o olaparibe, quando disponíveis, seriam a terapia de escolha para a maioria dos oncologistas (71%) caso não haja progressão da doença após quatro meses. A seleção dos tratamentos é usualmente baseada em critérios clínicos (por exemplo, performance status, função hepática). Em cerca de 45% dos doentes é utilizado FOLFIRINOX/mFOLFIRINOX como terapia de primeira linha. Um esquema com Gemcitabina + nab-paclitaxel é usado em 35% dos doentes como terapia de segunda linha. Conclusões: Os médicos em Portugal apoiam o papel crescente do tratamento individualizado no ACDPm, cuja seleção deve ser baseada na subtipagem tumoral e no perfil molecular. São necessários mais esforços para capacitar as equipas multidisciplinares, desenvolver práticas clínicas padronizadas e otimizar a implementação de novas terapias-alvo.
