Behavioral Changes and Long-Term Cortical Thickness Alterations in Women with Fibromyalgia

ObjectivesThe purpose of this study was to examine long-term brain and behavioral changes in patients with fibromyalgia (FM) compared to healthy individuals. MethodsData from 33 female volunteers with FM and 33 healthy controls women paired by age and school degree were used to analyze the cortical thickness from high-resolution T1-weighted magnetic resonance imaging (MRI) obtained through a 3T-MRI scanner. Additionally, the Toronto Alexithymia Scale, the Positive and Negative Affect Scale, the emotion regulation questionnaire (ERQ), and the Hamilton Depression and Anxiety rating scales were used to evaluate the behavioral changes. ResultsThe findings indicate significant cortical structure differences in the right cerebral hemisphere between groups in the insular anterior cortex precentral and postcentral gyrus (P < .001). The FM group scored higher for alexithymia (P < .01), negative affect (P < .01), anxiety (P < .01), and depression (P < .01) symptoms, on the other hand, scored lower for positive affect (P < .01). No differences were found on the left cerebral hemisphere. Furthermore, there was a negative correlation between the right insular anterior cortex and Toronto Alexithymia Scale (P < .001). ConclusionThis study showed long-term brain and behavioral changes in patients with FM, suggesting notable neurophysiological alterations associated with this chronic pain condition. It provides new insights into how FM may affect brain health and potential biomarkers for the condition.

Health workforce needs in Malawi: analysis of the Thanzi La Onse integrated epidemiological model of care

BackgroundTo make the best use of health resources, it is crucial to understand the healthcare needs of a population—including how needs will evolve and respond to changing epidemiological context and patient behaviour—and how this compares to the capabilities to deliver healthcare with the existing workforce. Existing approaches to planning either rely on using observed healthcare demand from a fixed historical period or using models to estimate healthcare needs within a narrow domain (e.g., a specific disease area or health programme). A new data-grounded modelling method is proposed by which healthcare needs and the capabilities of the healthcare workforce can be compared and analysed under a range of scenarios: in particular, when there is much greater propensity for healthcare seeking.MethodsA model representation of the healthcare workforce, one that formalises how the time of the different cadres is drawn into the provision of units of healthcare, was integrated with an individual-based epidemiological model—the Thanzi La Onse model—that represents mechanistically the development of disease and ill-health and patients’ healthcare seeking behaviour. The model was applied in Malawi using routinely available data and the estimates of the volume of health service delivered were tested against officially recorded data. Model estimates of the “time needed” and “time available” for each cadre were compared under different assumptions for whether vacant (or established) posts are filled and healthcare seeking behaviour.ResultsThe model estimates of volume of each type of service delivered were in good agreement with the available data. The “time needed” for the healthcare workforce greatly exceeded the “time available” (overall by 1.82-fold), especially for pharmacists (6.37-fold) and clinicians (2.83-fold). This discrepancy would be largely mitigated if all vacant posts were filled, but the large discrepancy would remain for pharmacists (2.49-fold). However, if all of those becoming ill did seek care immediately, the “time needed” would increase dramatically and exceed “time supply” (2.11-fold for nurses and midwives, 5.60-fold for clinicians, 9.98-fold for pharmacists) even when there were no vacant positions.ConclusionsThe results suggest that services are being delivered in less time on average than they should be, or that healthcare workers are working more time than contracted, or a combination of the two. Moreover, the analysis shows that the healthcare system could become overwhelmed if patients were more likely to seek care. It is not yet known what the health consequences of such changes would be but this new model provides—for the first time—a means to examine such questions.

Identifying the psychological effects of nocebo education: results from two pre-registered experiments

Providing treatment side effect information to patients increases the risk of harm due to the nocebo effect. Nocebo education, in which patients learn about nocebo effects, is a novel strategy that can be used across a variety of situations and individuals to decrease unpleasant treatment side effects. It is currently unclear which psychological changes are induced by nocebo education, which is information required to maximize this intervention. Two pre-registered studies investigated the effects of nocebo education on side effect expectations, side effect control beliefs, feelings toward treatments, intentions to avoid or seek side effect information, and perceptions of treatment efficacy. In Study 1 (N = 220), adult participants either watched or did not watch a nocebo education intervention video prior to reading vignettes about receiving a surgical treatment for pain and a medication for pain. Study 2 (N = 252) was similar to Study 1, with the inclusion of a health behavior video control group and participants only reading about a medication treatment for pain. In both experiments, nocebo education reduced global side effect expectations and increased side effect self-efficacy beliefs. Nocebo education also increased intentions to avoid side effect information and decreased intentions to seek more side effect information. Evidence was inconclusive on whether nocebo education changes affective associations with the treatments. The findings demonstrate that nocebo education has a multi-faceted influence with the potential to change patient behavior. The results can be used to improve the management of adverse treatment side effects.

Time preference shifts in medical decision-making after serious illness

This study explores the impact of serious illnesses, such as cancer, on patients' time preferences in medical decision-making. Specifically, we assess how patients value extending their lifespan by one year under varying survival prognoses through three experimental studies. The findings reveal that patients exhibit a higher Subjective Discount Rates (SDR) in their medical decisions after a serious illness diagnosis. Notably, this difference in individual health also affects the time preferences of their family members. Additionally, the subjective contextual setting of the illness can also increase an individual's SDR levels. The research highlights a tendency for patients and families facing a potential short life expectancy to focus more on immediate concerns, leading to potentially shortsighted and irrational medical choices. This behavior often results in regret during the end-of-life stage. These insights are vital for healthcare professionals in optimizing treatment plans and for policymakers in understanding patient behaviors more comprehensively. The study emphasizes the need for considering psychological and behavioral changes in patients grappling with severe health challenges.

COVID-19 and autoimmune rheumatic disease: behavioural changes adopted by patients amid the pandemic.

Amid concerns about severe COVID-19 in patients with autoimmune rheumatic disease (AIRD) during the outbreak, it is crucial to explore behavioural changes, whether healthy or unhealthy, arising from this patient population in response to the changing healthcare environment. To investigate COVID-19-driven behavioural changes in patients with AIRD. This observational study invited patients who attended the rheumatology clinic of the Korle Bu Teaching Hospital from 1 August 2020 to 1 July 2021, to respond to a survey questionnaire distributed on the patient's WhatsApp platform. Variables observed were changes in patient behaviour and decision-making related to medication, healthcare service utilisation and clinical advice. Results for 233 patients were analysed in the study, the majority (89.7%) of whom were women. The most significant behavioural changes were a reduction in hydroxychloroquine (HCQ) dosage, adoption of telemedicine for clinical consultation and keen adherence to protective/preventive health measures. Patients also expressed anxiety regarding the risk of contracting COVID-19 (52.5%), infecting their families (66.5%) and losing income (50.2%) due to the pandemic. Women and students were more likely to engage in self-isolation/shielding behaviour. Employed participants practised social distancing more, reduced HCQ dosage and had more fear of losing income. Having mixed connective tissue disease is associated with being anxious about the risk of COVID-19 infection. The COVID-19 pandemic has resulted in behaviour changes among patients with AIRD. Despite the perceived risk, most of these patients continue to adhere to their prescribed medication regimens, especially maintaining the dosage of traditional immunosuppressive agents.

The Effect of Wudhu Spiritual Therapy in Controlling Emotions in Patients at Risk of Violent Behavior

In the Limboto Health Centre working area, the behavioral changes of patients at risk of violent behavior were found to be that these patients had never received spiritual ablution therapy and were only given medication as prescribed or recommended. Mental disorders affect 970 million people worldwide. This study aims to determine whether ablution spiritual healing helps patients at risk of violent behavior in the Limboto Health Centre working area to control their emotions. Pre exploratory examination plan with one collection pretest-posttest configuration approach, the population of patients in danger of violent behavior in the working area of Limboto Community Group Welfare Centre, number of tests 15 people with complete examination procedures, information collected using the perception of signs and side effects sheet of patients in danger of violent behavior and tried using matched t-test measured parametric test. Results showed that before being given medication for otherworldly bathing treatment, all patients gave indications and side effects that generally appear in patients in danger of violent behavior. Still, after intercession, patients have the option to get mediation. control their feelings after being given bathing treatment given the consequences caused by paying attention to the symptoms and side effects. The p.value obtained from the paired t-test was 0.001 which is smaller than the value of 0.05. It was established in the Limboto Health Centre working area that the spiritual therapy of ablution helps patients at risk of violent behavior to control their emotions. Therefore, the health center is expected to support medical treatment to achieve more effective results in addition to using medical therapy which includes the administration of drugs

Behavioral Changes after Traumatic Brain Injury: A Systematic Review and Meta-analysis on the Frontal Systems Behavior Scale

Objective. To analyze the behavioral changes of patients with traumatic brain injury (TBI) based on their performance on the Frontal Systems Behavior Scale (FrSBe). Method. We performed a systematic review andmeta-analysis of original articles that used the FrSBe scale in patients with TBI from the time of publication of the instrument (year 1999) to February 2022, using PubMed, Scopus, and EBSCO databases. Results. The searchyielded a total of 4318 records, of which 28 met the selection criteria. The studies reported that patientswithTBI showed impairments in some domainsassessed by the FrSBe: apathy and executive dysfunction. Conclusions. The results are consistent with behavioral impairments frequently reportedin TBI patients. Therefore, the FrSBe is presented as a useful and effective tool for the detection of behavioral changes in this population.

SLEEP QUALITY AND AVOIDANCE BEHAVIOR IN COMBATANTS WITH POST-TRAUMATIC STRESS DISORDER

Introduction. Post-traumatic stress disorder (PTSD) is often characterized by various symptoms that result in behavioral changes in patients, among which sleep disturbances and avoidant behavior are commonly observed. However, despite evidence indicating a complex bilateral relationship between emotions and sleep, only few studies have explored the associations between sleep disturbances and avoidant behavior in the context of PTSD. The aim of the study is to assess the severity of avoidant behaviour and insomnia in combatants with posttraumatic stress disorder. Materials and methods. We conducted a clinical study of 45 combatants who were divided into 2 groups: group 1 (n=24) included combatants with PTSD; group 2 (n=21) consisted of combatants without PTSD. The Pittsburgh Sleep Quality Questionnaire was used to analyse sleep quality, namely subjective sleep quality, sleep latency, sleep duration, sleep efficiency, sleep disturbances, sleep medication use, and daily dysfunction. Avoidance behavior was measured using a multidimensional experience avoidance questionnaire. Results. We found that group 1 demonstrated worse subjective sleep quality (p=0.002), longer sleep latency (p&lt;0.001), lower sleep efficiency (p=0.019) and more severe sleep disturbances (p&lt;0.001). There were no statistically significant differences between the groups in terms of sleep duration, severity of sleeping pills use, and daily dysfunction. The overall severity of sleep quality disorders was higher in group 1 compared to group 2 (p&lt;0.001). Avoidance behavior (p=0.007) and repression and denial (p&lt;0.001) were more pronounced in group 1 compared to group 2. At the same time, group 1 had lower stress endurance (p&lt;0.001). The overall level of experiental avoidance in group 1 was higher than in group 2 (p&lt;0.001). Numerous associations between sleep quality characteristics and experiental avoidance were found as well. Conclusions. The study has revealed that combatants with PTSD have more pronounced manifestations of behavioural avoidance, repression and denial, as well as a lower level of stress endurance. At the same time, combatants with PTSD demonstrate a deterioration in the subjective quality of sleep, a decrease in its effectiveness and an increase in the severity of its disturbances. It has been found that avoidance behavior in combatants has numerous connections with the characteristics of sleep quality that may be suggested as a potential factor for improving psychotherapeutic interventions.

Interpreting Change in Disorders of Consciousness Using the Coma Recovery Scale-Revised.

The purpose of this study was to differentiate clinically meaningful improvement or deterioration from normal fluctuations in patients with disorders of consciousness (DoC) following severe brain injury. We computed indices of responsiveness for the Coma Recovery Scale-Revised (CRS-R) using data from a clinical trial of 180 participants with DoC. We used CRS-R scores from baseline (enrollment in a clinical trial) and a 4-week follow-up assessment period for these calculations. To improve precision, we transformed ordinal CRS-R total scores (0-23 points) to equal-interval measures on a 0-100 unit scale using Rasch Measurement theory. Using the 0-100 unit total Rasch measures, we calculated distribution-based 0.5 standard deviation (SD) minimal clinically important difference, minimal detectable change using 95% confidence intervals, and conditional minimal detectable change using 95% confidence intervals. The distribution-based minimal clinically important difference evaluates group-level changes, whereas the minimal detectable change values evaluate individual-level changes. The minimal clinically important difference and minimal detectable change are derived using the overall variability across total measures at baseline and 4 weeks. The conditional minimal detectable change is generated for each possible pair of CRS-R Rasch person measures and accounts for variation in standard error across the scale. We applied these indices to determine the proportions of participants who made a change beyond measurement error within each of the two subgroups, based on treatment arm (amantadine hydrochloride or placebo) or categorization of baseline Rasch person measure to states of consciousness (i.e., unresponsive wakefulness syndrome and minimally conscious state). We compared the proportion of participants in each treatment arm who made a change according to the minimal detectable change and determined whether they also changed to another state of consciousness. CRS-R indices of responsiveness (using the 0-100 transformed scale) were as follows: 0.5SD minimal clinically important difference = 9 units, minimal detectable change = 11 units, and the conditional minimal detectable change ranged from 11 to 42 units. For the amantadine and placebo groups, 70% and 58% of participants showed change beyond measurement error using the minimal detectable change, respectively. For the unresponsive wakefulness syndrome and minimally conscious state groups, 54% and 69% of participants changed beyond measurement error using the minimal detectable change, respectively. Among 115 participants (64% of the total sample) who made a change beyond measurement error, 29 participants (25%) did not change state of consciousness. CRS-R indices of responsiveness can support clinicians and researchers in discerning when behavioral changes in patients with DoC exceed measurement error. Notably, the minimal detectable change can support the detection of patients who make a "true" change within or across states of consciousness. Our findings highlight that the continued use of ordinal scores may result in incorrect inferences about the degree and relevance of a change score.

Behavioral changes in patients with Prader-Willi syndrome receiving diazoxide choline extended-release tablets compared to the PATH for PWS natural history study

BackgroundPrader-Willi syndrome (PWS) is a rare neurobehavioral-metabolic disease caused by the lack of paternally expressed genes in the chromosome 15q11-q13 region, characterized by hypotonia, neurocognitive problems, behavioral difficulties, endocrinopathies, and hyperphagia resulting in severe obesity if energy intake is not controlled. Diazoxide choline extended-release (DCCR) tablets have previously been evaluated for their effects on hyperphagia and other behavioral complications of people with PWS in a Phase 3 placebo-controlled study of participants with PWS, age 4 and older with hyperphagia (C601) and in an open label extension study, C602.MethodsTo better understand the longer-term impact of DCCR, a cohort from PATH for PWS, a natural history study that enrolled participants with PWS age 5 and older, who met the C601 age, weight and baseline hyperphagia inclusion criteria and had 2 hyperphagia assessments ≥ 6 months apart, were compared to the C601/C602 cohort. Hyperphagia was measured using the Hyperphagia Questionnaire for Clinical Trials (HQ-CT, range 0–36). The primary analysis used observed values with no explicit imputation of missing data. A sensitivity analysis was conducted in which all missing HQ-CT assessments in the C601/C602 cohort were assigned the highest possible value (36), representing the worst-case scenario. Other behavioral changes were assessed using the Prader-Willi Syndrome Profile questionnaire (PWSP).ResultsRelative to the PATH for PWS natural history study cohort, the DCCR-treated C601/C602 cohort showed significant improvements in HQ-CT score at 26 weeks (LSmean [SE] -8.3 [0.75] vs. -2.5 [0.43], p < 0.001) and 52 weeks (LSmean [SE] -9.2 [0.77] vs. -3.4 [0.47], p < 0.001). The comparison between the cohorts remained significant in the worst-case imputation sensitivity analysis. There were also significant improvements in all domains of the PWSP at 26 weeks (all p < 0.001) and 52 weeks (all p ≤ 0.003) for C601/C602 participants compared to the PATH for PWS participants.ConclusionLong-term administration of DCCR to people with PWS resulted in changes in hyperphagia and other behavioral complications of PWS that are distinct from the natural history of the syndrome as exemplified by the cohort from PATH for PWS. The combined effects of administration of DCCR should reduce the burden of the syndrome on the patient, caregivers and their families, and thereby may benefit people with PWS and their families.Trial RegistrationClinical study C601 was originally registered on ClinicalTrials.gov on February 22, 2018 (NCT03440814). Clinical study C602 was originally registered on ClinicalTrials.gov on October 22, 2018 (NCT03714373). PATH for PWS was originally registered on ClinicalTrials.gov on October 24, 2018 (NCT03718416).

A pilot randomized controlled trial of an online intervention for Hodgkin lymphoma survivors to increase knowledge about late effects and recommended screening.

Hodgkin lymphoma (HL) survivors who received chest radiotherapy are at risk for breast cancer and cardiovascular disease, but screening adherence is low. We assessed the acceptability/feasibility of a web-based educational intervention and its impact on knowledge of health risks and screening. HL survivors were randomized to either an interactive online educational intervention or handouts only. Surveys were completed at baseline and 3months post-intervention. We described the acceptability/feasibility of the intervention and compared knowledge between groups. Fifty-two HL survivors participated; 27 in the intervention group and 25 in the control group. Eighteen (66%) intervention participants completed the intervention and reported high acceptability (89-100%). At baseline, adherence to breast cancer screening was low across all participants. Post-intervention, those in the intervention group more often than controls correctly identified breast cancer and echocardiogram screening guidelines (35% vs. 28%, P = 0.02 and 82% vs. 52%, P = 0.04) and reported knowing how to address potential complications from cancer treatments (87% vs. 64%, P = 0.03). We detected no increase in screening behavior post-intervention. Online education modules for high-risk HL survivors are an acceptable method to improve knowledge of health risks and screening guidelines. Future interventions should focus on improving screening uptake in this population. Web-based learning can be useful in increasing cancer survivor knowledge of their unique risks and screening recommendations but does not necessarily change patient behavior. Involvement in a cancer survivorship program can help assess individual barriers and monitor uptake of screening.

Brief Intervention as a Method to Reduce Z-Hypnotic Use by Older Adults: Feasibility Case Series.

Z-hypnotics or z-drugs are commonly prescribed for insomnia and sleep difficulties in older adults. These drugs are associated with adverse events and dependence and are not recommended for long-term use. Despite evidence of older adults being more sensitive to a wide array of adverse events and clinical guidelines advocating limiting use, inappropriate use in this population is still prevalent. Previous intervention studies have focused mainly on prescriber information. Simple, individually focused intervention designs are less studied. Brief intervention (BI) is a simple, easily transferable method mainly used to treat patients at risk of alcohol overuse. Our objective was to design and test the feasibility and acceptability of a BI intervention adapted to address individual, inappropriate use of z-hypnotics among older adults. This preparatory study aimed to optimize the intervention in advance of a quantitative randomized controlled trial investigating the treatment effect in a larger population. This feasibility case series was conducted at Akershus University Hospital, Norway, in autumn 2021. We included 5 adults aged ≥65 years with long-term (≥4 weeks) use of z-hypnotics and 2 intervening physicians. Additionally, 2 study investigators contributed with process evaluation notes. The BI consists of information on the risk of inappropriate use and individualized advice on how to reduce use. The focus of the intervention is behavioral and aims, in cooperation with the patient and based on shared decision-making, to change patient behavior regarding sleep medication rather than physician-based detoxification and termination of z-hypnotic prescriptions. Qualitative and descriptive quantitative data were collected from intervening physicians, study investigators, and participants at baseline, immediately after the intervention, and at the 6-week follow-up. Data were obtained from 2 physicians, 2 study investigators, and 5 participants (4 women) with a median age of 84 years. The average time spent on the BI consultation was 15 minutes. All 5 participants completed the intervention without problems. The participants and 2 intervening physicians reported the intervention as acceptable and were satisfied with the delivery of the intervention. After the intervention, 2 participants stopped their use of z-hypnotics completely and participated in the follow-up interview. Study investigators identified logistical challenges regarding location and time requirements. Identified aspects that may improve the intervention and reduce dropouts included revising the intervention content, focusing on rebound insomnia, adding an information leaflet, and supporting the patient in the period between the intervention and follow-up. The notion that the intervention should best be located and conducted by the patient's own general practitioner was supported by the participants. We identified important aspects to improve the designed intervention and found that the BI is feasible and acceptable for incorporation into a larger randomized trial investigating the treatment effect of BI for reducing z-hypnotic use by older adults.

Offloading and adherence through technological advancements: Modern approaches for better foot care in diabetes.

This manuscript aims to provide a review and synthesis of contemporary advancements in footwear, sensor technology for remote monitoring, and digital health, with a focus on improving offloading and measuring and enhancing adherence to offloading in diabetic foot care. A narrative literature review was conducted by sourcing peer-reviewed articles, clinical studies, and technological innovations. This paper includes a review of various strategies, from specifically designed footwear, smart insoles and boots to using digital health interventions, which aim to offload plantar pressure and help prevent and manage wounds more effectively by improving the adherence to such offloading. In-house specially made footwear, sensor technologies remotely measuring pressure and weight-bearing activity, exemplified for example, through applications like smart insoles and SmartBoot, and other digital health technologies, show promise in improving offloading and changing patient behaviour towards improving adherence to offloading and facilitating personalised care. This paper introduces the concept of gamification and emotive visual indicators as novel methods to enhance patient engagement. It further discusses the transformative role of digital health technologies in the modern era. The integration of technology with footwear and offloading devices offers unparallelled opportunities for improving diabetic foot disease management not only through better offloading but also through improved adherence to offloading. These advancements allow healthcare providers to personalise treatment plans more effectively, thereby promising a major improvement in patient outcomes in diabetic foot ulcer healing and prevention.

Cardiovascular disease risk communication and prevention: a meta-analysis.

Knowledge of quantifiable cardiovascular disease (CVD) risk may improve health outcomes and trigger behavioural change in patients or clinicians. This review aimed to investigate the impact of CVD risk communication on patient-perceived CVD risk and changes in CVD risk factors. PubMed, Embase, and PsycINFO databases were searched from inception to 6 June 2023, supplemented by citation analysis. Randomized trials that compared any CVD risk communication strategy versus usual care were included. Paired reviewers independently screened the identified records and extracted the data; disagreements were resolved by a third author. The primary outcome was the accuracy of risk perception. Secondary outcomes were clinician-reported changes in CVD risk, psychological responses, intention to modify lifestyle, and self-reported changes in risk factors and clinician prescribing of preventive medicines. Sixty-two trials were included. Accuracy of risk perception was higher among intervention participants (odds ratio = 2.31, 95% confidence interval = 1.63 to 3.27). A statistically significant improvement in overall CVD risk scores was found at 6-12 months (mean difference = -0.27, 95% confidence interval = -0.45 to -0.09). For primary prevention, risk communication significantly increased self-reported dietary modification (odds ratio = 1.50, 95% confidence interval = 1.21 to 1.86) with no increase in intention or actual changes in smoking cessation or physical activity. A significant impact on patients' intention to start preventive medication was found for primary and secondary prevention, with changes at follow-up for the primary prevention group. In this systematic review and meta-analysis, communicating CVD risk information, regardless of the method, reduced the overall risk factors and enhanced patients' self-perceived risk. Communication of CVD risk to patients should be considered in routine consultations.

Comparing Lifestyle and Behavior of Post-Bariatric Surgery and Participants with Obesity: A Community-Based Cross-Sectional Study.

There is a paucity of research dedicated to exploring behavioral change in patients following bariatric surgery. However, there is a need for comparison analysis of individuals with obesity who have received surgical treatment and those who have not opted for any surgical procedures for weight loss. This study is designed to scrutinize the lifestyle choices, behavioral patterns, psychological elements, and eating habits of individuals who have undergone bariatric surgery, in contrast to those with obesity who have not undergone such a procedure. This study is a secondary analysis from Sharik Diet and Health National Survey (SDHNS) dataset, which is a cross-sectional investigation covering the period from 2020 to 2022. The study focused on demographic factors like age, gender, educational attainment, and monthly earnings. Furthermore, other variables such as physical activity, leisure and workplace sitting habits, smoking patterns, strategies for managing weight, and eating and consumption behaviors were also examined. Out of the initial 15,980 participants reached, 4,069 satisfied the study's inclusion criteria. Bariatric surgery was reported by 806 participants (19.8%). Upon comparing three obesity status groups - The participants who underwent bariatric surgery with or without obesity, those with obesity who did not opt for any surgical weight loss measure, the analysis found that the three obesity status groups were significantly different in 21 variables from a total of 26. Moreover, a logistic regression analysis revealed that 11 variables influenced persistent obesity in the post-surgery phase, as opposed to those who successfully lost weight. These variables included advanced age, limited education, being female, lower income, waterpipe smoking habits, and the consumption of carbonated drinks. This study showed that inability to lose weight after bariatric surgery are linked to poor lifestyle choices and behavior compared to those who were able to lose weight after the surgery.

Effectiveness of a Health Education Program for Patients Who Had a Stroke and Their Caregivers by Controlling Modifiable Risk Factors to Reduce Stroke Recurrence in a Tertiary Hospital in Bangladesh: Protocol for a Randomized Controlled Trial.

Stroke is a significant public health concern that causes severe and long-lasting disability. The recurrence of stroke is increasing due to lack of patients' knowledge and compliance with treatment to control modifiable risk factors and lifestyle changes. Health education can be an effective way to increase knowledge about behavioral changes in patients who had a stroke. The aim of this study is to evaluate the effectiveness of a health education program in Bangladesh for patients who had their first stroke and their family caregivers in order to reduce the recurrence of stroke by controlling modifiable risk factors. This is a parallel, open-label, prospective randomized controlled trial conducted at the National Institute of Neurosciences & Hospital in Dhaka, Bangladesh. We enrolled ≥18-year-old patients of both sexes who had a history of first stroke attack (transient ischemic attack, hemorrhagic stroke, lacunar stroke, atherothrombotic stroke, or cardioembolic stroke). We stratified patients into those aged <65 years and those aged ≥65 years and according to types of strokes for randomization. Our estimated sample size was 432. The intervention group receives face-to-face counseling on lifestyle modifications, blood pressure monitoring, and medication compliance-related health education during enrollment and monthly follow-ups. However, the control group receives only usual care from the hospital. The primary end point of this study is the reduction in the stroke recurrence rates at the end of the 12-month follow-up period. The secondary end points are to (1) assess the occurrence of all adverse events such as other cardiac events and all-cause mortality, (2) evaluate the status of the controlling modifiable risk factors such as blood pressure, glycated hemoglobin, and non-high-density lipoprotein cholesterol, (3) assess the knowledge related to stroke by using the investigator-developed questionnaire, (4) evaluate the lifestyle behavior related to stroke by using the investigator-developed questionnaire, (5) assess medication adherence, and (6) evaluate the quality of life of patients who had a stroke and their family caregivers. The evaluation points will be at baseline, 6 months, and 12 months for both groups. Patients' enrollment started on October 2022, and follow-up will be completed in March 2024. A total of 432 participants were included in both the intervention (n=216) and control groups (n=216). This study was approved by the institutional review board and the ethics review board of the National Institute of Neurosciences & Hospital (IRB/NINSH/2022/151) on August 30, 2022. Our health education program is expected to reduce the recurrence of stroke and improve the quality of life of patients who have had the first stroke. The results of this study will provide insights into the importance of health education for (self)-management and prevention of stroke.

Social cognition and behavioral changes in patients with posterior cortical atrophy.

Posterior cortical atrophy (PCA) is a rare neurodegenerative condition characterized by progressive visual and visuospatial dysfunction. The consensus criteria state that patients should present "relatively spared behavior and personality" in early stages. However, limited research has focused on these symptoms in PCA. This study compared 157 patients with PCA in early stages of the disease with 352 healthy controls (HC), 202 typical AD (tAD), and 177 logopenic variant primary progressive aphasia (lvPPA) patients from the National Alzheimer's Coordinating Center (NACC) dataset. They were compared using clinician ratings of behavioral symptoms, informant- and clinician-filled questionnaires and patient-facing tests of behavior and social cognition. Results showed that PCA individuals exhibited many behavioral symptoms, the more frequently reported being anxiety, depression, apathy, and irritability. During cognitive testing, clinicians observed disorganized and reactive behaviors, but no insensitive behaviors. Informant reports indicated that PCA patients exhibited higher levels of inhibition and anxiety in response to stimuli associated with non-reward, novelty, and punishment. Social norms knowledge and empathy were overall preserved, although slight decreases in perspective-taking and socioemotional sensitivity were observed on informant-rated questionnaires. Except for more elevated neuropsychiatric symptoms in tAD, the three AD variants had similar profiles. Our findings provide insights into the social cognition and behavioral profiles of PCA, highlighting patterns of preservations and mild impairments, even in the early stages of the disease. These results contribute to a more complete understanding of non-visual symptoms in PCA and have implications for diagnostic and intervention strategies.

Prefrontal event-related potential markers in association with mild cognitive impairment.

Alzheimer's disease (AD) is among the leading contributors of dementia globally with approximately 60-70% of its cases. Current research is focused on the mild cognitive impairment (MCI), which is associated with cognitive decline but does not disrupt routine activities. Event-related potential (ERP) research is essential in screening patients with MCI. Low-density channel electroencephalography (EEG) is frequently used due to its convenience, portability, and affordability, making it suitable for resource-constrained environments. Despite extensive research on neural biomarkers for cognitive impairment, there is a considerable gap in understanding the effects on early stages of cognitive processes, particularly when combining physiological and cognitive markers using portable devices. The present study aimed to examine cognitive shortfalls and behavioral changes in patients with MCI using prefrontal selective attention ERP recorded from a prefrontal two-channel EEG device. We assessed cognitive decline using the Mini-Mental State Examination (MMSE) and the Seoul Neuropsychological Screening Battery (SNSB). We administered auditory selective attention tasks to 598 elderly participants, including those with MCI (160) and cognitively normal (CN) individuals (407). We conducted statistical analyses such as independent t-tests, Pearson's correlations, and univariate and multiple logistic regression analyses to assess group differences and associations between neuropsychological tests, ERP measures, behavioral measures, and MCI prevalence. Our findings revealed that patients with MCI demonstrated slower information-processing abilities, and exhibited poorer task execution, characterized by reduced accuracy, increased errors, and higher variability in response time, compared to CN adults. Multiple logistic regression analyses confirmed the association between some ERP and behavioral measures with MCI prevalence, independent of demographic and neuropsychological factors. A relationship was observed between neuropsychological scores, ERP, and behavioral measures. The slower information processing abilities, and poor task execution in the MCI group compared to the CN individuals suggests flawed neurological changes and reduced attentional maintenance during cognitive processing, respectively. Hence, the utilization of portable EEG devices to capture prefrontal selective attention ERPs, in combination with behavioral assessments, holds promise for the identification of mild cognitive deficits and neural alterations in individuals with MCI. This approach could potentially augment the traditional neuropsychological tests during clinical screening for MCI.
