ABSTRACT

This paper estimates the impact of Daylight Saving Time (DST) on deaths from suicide and substance abuse in the United States. Using Multiple Cause-of-Death Mortality Data from the National Vital Statistics System of the National Center for Health Statistics from 1979 to 1988, the effect is identified in two ways: a regression discontinuity design that exploits discrete time changes in the Spring and Fall; and a fixed effects model that uses a policy change and a switching mechanism that introduces random variation to DST’s start and end dates. This is one of the first attempts to estimate the impact of DST on deaths due to suicide and substance abuse and the first to use either identification strategy. The results from both methods suggest that the sleep disruptions during the Spring transition cause the suicide rate to rise by 6.25 percent and the death rate from suicide and substance abuse combined to increase by 6.59 percent directly after the time change. There is no evidence for any change in these outcomes during the Fall transition. The contrasting results from Spring to Fall suggest the entire effect can be attributed to disruptions in sleep patterns rather than changes in ambient light exposure.

ABSTRACT

BACKGROUND: Although the ubiquitous presence of ambiguity and uncertainty in medical practice is widely acknowledged, a greater understanding of contextual factors for educators to consider in helping students learn to respond to ambiguity and uncertainty adaptively is needed. Drawing on self-determination theory, the purpose of this study was to explore the unique roles of basic psychological needs-autonomy, competence and relatedness-in medical students’ tolerance of ambiguity and uncertainty.

METHODS: This was a cross-sectional survey study of third-year medical students (n = 70) at a large Canadian university. In regression analysis, the three basic psychological needs were entered as predictors of medical students’ tolerance of ambiguity and uncertainty while controlling for students’ age and gender.

RESULTS: Of the three needs, the need for competence was determined to be statistically significant in relation to students’ tolerance of ambiguity and uncertainty (β = 0.326; p = 0.038). The needs for autonomy and relatedness were determined to be not statistically significant (β = -0.170; p = 0.274 and β = 0.154; p = 0.218, respectively).

DISCUSSION: We observed that medical students, who experienced satisfaction of the need for competence in the learning environment, reported greater tolerance of ambiguity and uncertainty. Potential implications for medical education are discussed, based on self-determination theory.

ABSTRACT

BACKGROUND: Infection has been a major cause of morbidity and mortality in systemic lupus erythematosus (SLE) patients. One of the infections encountered in SLE patients is candidiasis. Therefore, we aimed to conduct a case-control study to explore the risk factors associated with candidiasis in SLE patients in our center.

METHODS: Medical records of 20 SLE patients with fungal infection were obtained, and a case-control study was conducted with an age and sex-matched control group of 20 patients. Data were obtained from the Cipto Mangunkusumo National General Hospital. SLE confirmatory diagnosis was based on Systemic Lupus Erythematosus International Collaborating Clinics (SLICC) 2012 criteria. Patients with comorbidities of various chronic diseases (diabetes, HIV, and chronic kidney disease) were excluded. Statistical analysis was conducted using the Mann-Whitney U test with statistical significance defined as a p-value < 0.05.

RESULT: Based on the analysis, a maximum corticosteroid dose of 24 (4-250) mg/day for the last one year was associated with the development of fungal infection (p = 0.047). Lower absolute lymphocyte count (748 cells/mm³ versus 1635 cells/mm³) was also associated with the occurrence of candidiasis in SLE patients (p = 0.008).

CONCLUSION: Physicians should be aware that corticosteroid use in SLE patients may cause candidiasis. Monitoring of maximum corticosteroid dose and absolute lymphocyte count is important to help prevent candidiasis. Patients should also be educated regarding the risk of candidiasis from corticosteroid use.

ABSTRACT

BACKGROUND: Pulmonary embolism (PE) is a common acute life-threatening cardiovascular disorder. It is the third most common cause of hospital-related death and early detection and management of PE are crucial. The study aimed to evaluate the association between vital signs and laboratory investigations with PE.

METHODS: This is a retrospective, hospital records-based, observational study, conducted among patients who were admitted to the emergency department of King Saud Medical City in Riyadh, Saudi Arabia with a suspected diagnosis of PE during the period of March 2021 to March 2022. Data were collected by searching patients’ files and recording demographic data, and information about the clinical presentation, workup, and outcome. Data were entered and analyzed using SPSS version 26 (IBM, Armonk, NY), utilizing Chi-square statistics to test differences between groups, and logistic regression analyses to identify predictors of PE.

RESULTS: The study included 92 patients, with a preponderance of females (70.7%), and those aged 40-60 years (51.1%). Diabetes mellitus (44.6%), and hypertension (30.4%) were the most common comorbidities among others, while shortness of breath (SOB) (83.7%), and chest pain (44.6%) were among the most commonly reported symptoms. A majority of patients had tachycardia (64.1%), while about half had low oxygen saturation (51.5%), and nearly one-third had tachypnea (29.3%), which was more predominant among those not diagnosed with PE. Logistic regression analysis revealed that SOB, respiratory rate, and oxygen saturation were the only significant predictors of PE.

CONCLUSION: Although being an integral part of the initial assessment in the hospital, measuring the vital signs is not always reflective of the likelihood of PE, and they should not be the only metric relied upon to make decisions about treatment approaches in patients with PE. Physicians should ensure the employment of evidence-based clinical prediction rules and guidelines when diagnosing and managing PE.

ABSTRACT

BACKGROUND: We assessed understanding of the obstetric consent form between patients with English and Spanish language preference.

METHODS: This observational study included pregnant patients who identified as Hispanic/Latinx with English or Spanish language preference (defined as what language the patient prefers to receive healthcare information) and prenatal care providers at a large academic medical center from 2018 to 2021. Patient demographics, language preference, literacy, numeracy, acculturation, comprehension of the obstetric consent, and provider explanations were collected.

RESULTS: We report descriptive statistics and thematic analysis with an inductive approach from 30 patients with English preference, 10 with Spanish preference, and 23 providers. The English group demonstrated 72% median correct responses about the consent form; the Spanish group demonstrated 61% median correct responses. Regardless of language, the participants demonstrated limited understanding of certain topics, such as risks of cesarean birth.

DISCUSSION: Overall comprehension of key information in an obstetric consent form was low, with differences in language groups, which highlights opportunities for improvements in communication across language barriers. Innovations in the communication of critical pregnancy information for patients with limited English proficiency need to be developed and tested.

ABSTRACT

INTRODUCTION: Chronic kidney disease (CKD) is known to be a risk factor for falls. In addition, numerous factors such as impaired body balance and loss of muscle mass were reported as risk factors for falls. Patients with CKD often have edema in their lower extremes. In Japan, edema, as well as physical factors, are listed as fall assessment items. Little is known about the relation between body functions and edema in patients with CKD. Thus, we conducted a multivariate regression analysis to investigate the factors related to knee extension muscle strength and dynamic balance in motion (TUG).

MATERIALS AND METHODS: Thirty patients with CKD participated in this study. The basic characteristics were sex, age, blood pressure, body mass index (BMI), and medications. The laboratory data were estimated glomerular filtration rate (eGFR), hemoglobin (Hb), and C-reactive protein (CRP). Edema and muscle mass was measured by using InBody S10 (Inbody Japan Inc., Tokyo, Japan). The balance function while standing at rest and motion was measured as the total trajectory length of the center of gravity and the index of postural stability (IPS) using a kinetogravicorder 7100 (Anima Inc., Tokyo, Japan). Dynamic balance was assessed by the timed up & go (TUG) test. Knee extension muscle strength was measured by the Micro Total Analysis System (μ-Tas) F-1 (Anima Inc., Tokyo, Japan) test. Nutritional assessment was measured by the geriatric nutritional risk index (GNRI). Activities of daily living were measured using the functional independence measure (FIM). We conducted a multivariate regression analysis to investigate the factors related to knee extension muscle strength and dynamic balance in motion.

RESULTS: Extracellular water/total body water (ECW/TBW) was not significantly correlated with balance at rest and IPS. The ECW/TBW was associated with knee extension muscle strength, TUG, albumin (Alb), Hb, and GNRI with statistical significance. After adjusting for sex and age, knee extension muscle strength was associated with ECW/TBW and TUG (p=0.044). The TUG was also associated with ECW/TBW after being adjusted for age and sex (p=0.046). Conclusion: Patients with CKD who have edema may have decreased knee extensor strength and body balance function. Investigation of knee extension muscle strength and the body balance test in addition to the presence of leg edema at the time of physical examination may help predict a functional decline in CKD patients.

ABSTRACT

Introduction Children were affected by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus during the first and second waves of the coronavirus disease 2019 (COVID-19 pandemic. Although the severity was less in children, the fear of contracting SARS-CoV-2 at the hospital might have led to a delayed health-seeking attitude. The objective of the study was tailored around emergency health care utilization affecting outcomes. The study was done to compare the trend concerning the utilization of pediatric healthcare and immunization services, changes in the profile of diseases, and the outcomes between the pre-COVID-19 period and the COVID-19 period in a tertiary care hospital. Methods This retrospective observational study was conducted in a tertiary care hospital in western Odisha. Data were collected retrospectively from different hospital registers (outpatient register, inpatient register, and immunization records) and analyzed between the pre-COVID-19 period (April 2019 to March 2020) and the COVID-19 period (April 2020 to March 2021) with appropriate statistical procedures. Results There was a 60%, 49.8%, 51.1%, and 25.5% reduction in outpatient attendance, indoor pediatric admissions, nutritional rehabilitation centre admissions, and newborn admissions, respectively in COVID-19 period as compared to the pre-COVID-19 period. The pediatric bed occupancy rate was reduced by 54.5%. Unfavourable outcomes (death, left against medical advice, and referral) were significantly high in hospitalized children (24% vs. 18.1%, p < 0.001). The reduction in hospitalization due to common conditions like acute respiratory tract infections, bronchiolitis and asthma, and acute gastroenteritis during COVID-19 was 76.5%, 86.2%, and 39.5%, respectively. A higher percentage of low birth weight and preterm (<34 weeks) babies were admitted to special neonatal care unit (SNCU) during the pandemic (61.8% vs. 58%, p < 0.05; 18.9% vs. 15.8%; p < 0.05 respectively). Conclusion The COVID-19 pandemic and the associated lockdown led to a significant decrease in pediatric and neonatal healthcare utilization. The impact of lower care-seeking and attendance resulting in poor patient-related outcomes (malnutrition, upsurge of vaccine-preventable diseases, disease-specific hospitalization, and mortality) post-pandemic is a real threat.

ABSTRACT

BACKGROUND: Genetic variants associated with acute side effects of radiotherapy in nasopharyngeal carcinoma (NPC) remain largely unknown.

METHODS: We performed a two-stage genome-wide association analysis including a total of 1084 patients, where 319 individuals in the discovery stage were genotyped for 688,783 SNPs using whole genome-wide screening microarray. Significant variants were then validated in an independent cohort of 765 patients using the MassARRAY system. Gene mapping, linkage disequilibrium, genome-wide association analysis, and polygenic risk score were conducted or calculated using FUMA, LDBlockShow, PLINK, and PRSice software programs, respectively.

RESULTS: Five SNPs (rs6711678, rs4848597, rs4848598, rs2091255, and rs584547) showed statistical significance after validation. Radiotherapy toxicity was more serious in mutant minor allele carriers of all five SNPs. Stratified analysis further indicated that rs6711678, rs4848597, rs4848598, and rs2091255 correlated with skin toxicity in patients of EBV positive, late stage (III and IV), receiving both concurrent chemoradiotherapy and induction/adjuvant chemotherapy, and with OR values ranging from 1.92 to 2.66. For rs584547, high occurrence of dysphagia was found in A allele carriers in both the discovery (P = 1.27 × 10^{– 6}, OR = 1.55) and validation (P = 0.002, OR = 4.20) cohorts. Furthermore, prediction models integrating both genetic and clinical factors for skin reaction and dysphagia were established. The area under curve (AUC) value of receiver operating characteristic (ROC) curves were 0.657 (skin reaction) and 0.788 (dysphagia).

CONCLUSIONS: Rs6711678, rs4848597, rs4848598, and rs2091255 on chromosome 2q14.2 and rs584547 were found to be novel risk loci for skin toxicity and dysphagia in NPC patients receiving radiotherapy.

ABSTRACT

BACKGROUND: Cochlospermum tinctorium and C. planchonii are two wide edible plants of sub-Saharan countries, e.g., Benin, widely used as food, medicine, dye, handicraft, etc. Unfortunately, the uncontrolled harvest of their rootstocks exposes them to local extension risk. To enhance knowledge on the determinants of their uses in Benin, this study aimed to (i) assess the use forms, use values, abundance and perceived spatiotemporal dynamics, (ii) determine how does local abundance or cultural patterns affect the use of Cochlospermum species, and (iii) assess local harvesting modes and conservation management practices.

METHODS: In total, 756 Dialog Partners through 27 ethnic groups were questioned countrywide using semi-structured interviews. Questions refer to local taxonomy, specific uses, organs sought, harvesting modes and local conservation strategies; afterward, local abundance of each species was assessed. Ethnobotanical indicators were analyzed through citation frequencies to obtain quantitative data. Comparison tests and statistical analyses were performed using R program.

RESULTS: C. tinctorium and C. planchonii are locally well known and involved into 83 specific uses, grouped into ten categories of which medicinal use was the main. The use values of C. planchonii (0.10 ± 0.19) and C. tinctorium (0.23 ± 0.20) varied significantly between the ethnic groups, and only C. tinctorium showed index of commercially value above 75% for some ethnic groups. The current abundance, about 84 and 97 tufts.ha^-1, respectively, for C. planchonii and C. tinctorium was perceived with a decline of 81.09% (C. tinctorium) and 73.7% (C. planchonii) of informants. Moreover, the Spearman’s correlation and Kruskal-Wallis tests performed revealed that the use values of C. tinctorium and C. planchonii were significantly correlated on the one hand with their local abundance and on the other hand with the investigated ethnic groups. About 42.3% of women produced the powder as principal activity, while more than 57% produced it mainly at the end of farm work. However, the conservation management was practiced by very few informants and consisted of partial harvesting of rootstocks (41.8%, only in southern Benin), and fallowing of harvesting areas (3.97%, only in northern Benin).

CONCLUSION: Facing the declining abundance and increasing market demand for rootstock powder of Cochlospermum species, existing local conservation strategies should be promoted and the domestication process should be initiated for sustainable management of these important wild edible plants before these important resources disappear completely in the wild.

ABSTRACT

BACKGROUND: Non-adherence in patients with bipolar disorder (BD) results in symptoms, such as aggravation, BD recurrence, emergency room visits, re-hospitalization, and poor psychosocial outcomes. Though non-adherence rates have been reported to range between 30-50% in patients with BD, the problem of adherence is often either overlooked by the physician or denied by the patient. An essential first step to enhancing medication adherence is to objectively estimate adherence. The Medication Event Monitoring System (MEMS), which is a pill bottle cap with a microprocessor, is an accurate device for assessing medication adherence. Using the MEMS, we aimed to measure medication adherence in patients with BD and evaluate the factors associated with and 6-month changes in medication adherence.

METHODS: Participants with BD were recruited from the psychiatric outpatient clinic of the Korea University Guro Hospital. The medication adherence of each participant was assessed using the MEMS, a self-report, pill count, and clinician rating. MEMS-measured adherence was reassessed after 6 months. Patient demographics were recorded and clinical assessments were conducted. Data were analyzed using Kappa statistics and Pearson’s correlation analysis.

RESULTS: Of the 59 participants, 50 records were included in the analysis. Patient adherence and adherence rate assessed by the MEMS were lower than those assessed by the other measures. MEMS-measured adherence was correlated more closely with pill counts than with self-reports or clinician ratings. MEMS-measured adherence was negatively associated with prescription duration and the Brief Psychiatric Rating Scale-Affect Subscale Score. Six-month changes in MEMS-measured adherence were positively associated with attitude toward drugs and negatively associated with weight gain assessed by the Udvalg for Kliniske Undersøgelser Side Effect Rating Scale.

CONCLUSIONS: Clinicians may have to consider the limited accuracy of self-reporting and clinician rating methods and exercise caution when assessing the medication adherence of patients with BD using these methods. Our findings may assist clinicians in the assessment and improvement of medication adherence in patients with BD and, consequently, may be useful for the treatment and prevention of BD recurrence.
