Sleep quality and screen time among university professors: impact of emergency remote teaching amidst COVID-19 crisis.

PURPOSE: Sleep plays a crucial role in maintaining physical and mental health. The COVID-19 pandemic has brought about unprecedented global changes, and disruptions in sleep quality have emerged as a challenge. The pandemic prompted a dramatic shift in the working landscape for university professors, necessitating emergency remote teaching (ERT). This transition substantially increased professors' screen time for academic and research endeavors. This study explores the relationship between screen time and sleep quality among university professors during the pandemic and examines associated factors, including psychological well-being. METHODS: An electronic survey, covering demographics, education, screen time, sleep quality, and mental health, was administered to professors who worked during the spring semester of 2020. Standardized measures were used to assess sleep quality and mental health. Correlations, Mann-Whitney tests, and multivariate regression explored associations between screen time, sleep quality, and other variables. RESULTS: One hundred sixty participants exhibited poor sleep quality, subthreshold insomnia, and mild depression. Increased screen time correlated with poorer sleep quality, elevated stress levels, and heightened depression severity. Evening screen users reported more insomnia than daytime users. Depression emerged as a significant predictor of poor sleep quality and insomnia, along with evening screen use. CONCLUSION: This study among university professors underscores the impact of screen time on sleep quality during the COVID-19 pandemic. Participants faced poor sleep, largely influenced by heightened screen time due to ERT. Considering these findings, this study emphasizes the importance of curbing daytime screen exposure and abstaining from screens in the evening, especially for university professors reliant on technology for their professional responsibilities.

Effect of ß-Lactam Plus Macrolide Versus Fluoroquinolone on 30-Day Readmissions for Community-Acquired Pneumonia.

BACKGROUND: Antibiotic therapy with a macrolide and ß-lactam or a fluoroquinolone for the empirical treatment of community-acquired pneumonia (CAP) in an inpatient non-intensive care setting is recommended per guidelines. Studies show that these treatments have similar outcomes, including death, adverse effects, and bacterial eradication. However, a comparison of 30-day readmission rates between these treatments is limited. STUDY QUESTION: To determine whether 30-day readmissions for patients treated for CAP in a regional hospital differed between a fluoroquinolone monotherapy and a ß-lactam plus macrolide combination therapy. STUDY DESIGN: Retrospective cohort study of patients aged ≥18 years with a CAP diagnosis who were admitted to the same regional hospital from December 1, 2011, through December 1, 2016. MEASURES AND OUTCOMES: Patients receiving a third-generation cephalosporin plus macrolide were compared with those receiving a respiratory fluoroquinolone. Exclusion criteria were concurrent or recent use of the study antibiotics; death, transfer, or transition to hospice; and diagnosis of hospital-acquired pneumonia or health care-associated pneumonia. The collected data were 30-day readmission rates, antibiotic regimens, demographic characteristics, and pneumonia severity index and comorbidity scores. Association between treatment group and readmissions was assessed with logistic regression. Association between readmissions and individual data points between the 2 treatment groups was calculated with multivariate regression and odds ratio (95% confidence interval). RESULTS: Of 432 patients, 171 met inclusion criteria (fluoroquinolone group, n = 101; ß-lactam plus macrolide group, n = 70). Thirty-day readmissions were not significantly different between the fluoroquinolone group and ß-lactam plus macrolide group (P = 0.58). Increased 30-day readmissions were independently associated with male sex and hospital length of stay (P < 0.05). Length of stay was approximately 3 days and did not differ between treatment groups. CONCLUSIONS: No difference was seen in 30-day readmissions between CAP patients who received fluoroquinolone monotherapy and those who received ß-lactam plus macrolide combination therapy.

Impact of reconceptualization response shift on rating of quality of life over time among people with advanced cancer.

BACKGROUND: People with cancer may experience change in what constitutes quality of life (QOL) over time as a result of the cancer progression (true change) or adaptation to the experience, considered as a response shift phenomenon. As individualized measures are ideally suited to explore response shift, this study aimed to estimate the extent to which reconceptualization response shift occurred over time in a cancer population and the impact of this response shift on estimates of change on QOL measures. METHODS: Ninety-seven people with advanced cancer completed the study measures including the Patient-Generated Index (PGI) at diagnosis (T0) and 1 year later (T1). The response shift indicator was the change in the number of areas nominated (range - 4 to + 3). Multivariate linear regression was used to estimate the effect of changing areas on change in the PGI score, single indicators of global QOL, and the EQ-5Dindex adjusted for age and sex. RESULTS: Approximately 72% of people in this sample either added or dropped areas over time. People who dropped more than two areas had higher PGI scores at T1 than T0 while people who added areas showed low PGI score. CONCLUSION: The results are consistent with the PGI framework as areas nominated tend to focus on negative aspects of QOL.

The Ottawa Panel guidelines on programmes involving therapeutic exercise for the management of hand osteoarthritis.

OBJECTIVE:: To identify programmes involving therapeutic exercise that are effective for the management of hand osteoarthritis and to provide stakeholders with updated, moderate to high-quality recommendations supporting exercises for hand osteoarthritis. METHODS:: A systematic search and adapted selection criteria included comparable trials with exercise programmes for managing hand osteoarthritis. Based on the evaluated evidence, a panel of experts reached consensus through a Delphi approach endorsing the recommendations. A hierarchical alphabetical grading system (A, B, C+, C, C-, D-, D, D+, E, F) was based on clinical importance (≥15%) and statistical significance ( P < 0.05). RESULTS:: Ten moderate- to high-quality studies were included. Eight studies with programmes involving therapeutic exercise (e.g. range of motion (ROM) + isotonic + isometric + functional exercise) seemed to be effective. Forty-six positive grade recommendations (i.e. A, B, C+) were obtained during short-term (<12 weeks) trials for pain, stiffness, physical function, grip strength, pinch strength, range of motion, global assessment, pressure pain threshold, fatigue and abductor pollicis longus moment and during long-term (>12 weeks) trials for physical function and pinch strength. CONCLUSION:: Despite that many programmes involving exercise with positive recommendations for clinical outcomes are available to healthcare professionals and hand osteoarthritis patients that aid in the management of hand osteoarthritis, there is a need for further research to isolate the specific effect of exercise components.

A review of the application, feasibility, and the psychometric properties of the individualized measures in cancer.

PURPOSE: To identify from the published literature the feasibility and the application of the individualized measures [Patient Generated Index (PGI), Schedule for the Evaluation of Individual Quality of Life (SEIQOL), and the short form of it (the direct weighting SEIQOL-DW)] in the context of cancer and to summarize the evidence on the psychometric properties of these measures. METHODS: Ovid Medline, PubMed, Embase, and CINAHL were searched up to April 2016. All studies were included if they reported information about the psychometric properties of the individualized measures and included patients diagnosed with any type of cancer at any age. Effect size (ES) was calculated to test for the responsiveness. RESULTS: Fifty-four full articles were reviewed. Full-text assessment of these articles resulted in 27 eligible studies that were included in our analysis. The majority of the studies (81%) reported data on the SEIQOL-DW, and only 15% on the PGI. Fourteen areas of quality-of-life (QOL) concerns were identified by patients using the PGI with the top 4 being family (90%), health (85%), finance (85%), and work (80%). At the global level, the correlation between the individualized and standard measures ranged from 0.45 to 0.49 and, at the symptom level, from 0.26 to 0.51. The ES of the individualized measures was high (ranged from 0.98 to 1.0) in the studies that expected high positive change compared to standard QOL measures (ES = 0.1). CONCLUSION: Individualized measures are feasible and acceptable among people with cancer and could easily be incorporated clinically and used in a research context. Individualized measures are sensitive to change and cover a wide range of patients QOL concerns in comparison with standard measures.

Comparison of captopril (0.5%) cream with diltiazem (2%) cream for chronic anal fissure: a prospective randomized double-blind two-centre clinical trial.

AIM: This study compared the efficacy of topical captopril with topical diltiazem in the treatment of chronic anal fissure (CAF). METHOD: Fifty patients aged between 15 and 75 years with CAF were included in a prospective randomized, double-blind clinical trial. They were randomly allocated to either captopril (0.5%) cream or diltiazem (2%) cream in a dose of 2 cm of cream on the perianal skin every 12 h for 8 weeks. The intensity of pain upon defaecation was evaluated every 10 days using a visual analogue scale. Bleeding on defaecation, pruritus and the presence of perianal irritation were also recorded before and during the trial. RESULTS: The average pain scores were lower in the diltiazem group on the 20th and 30th days. From day 40 to the end of the trial the average pain scores of the two groups did not differ significantly. There were no significant differences in bleeding or perianal irritation between the groups, but the incidence of pruritus was considerably higher in the captopril group, and at the end of the trial 45.8% of the patients in this group still suffered from pruritus. CONCLUSION: Topical captopril and diltiazem were found to be equally effective in the management of pain, bleeding and perianal irritation due to CAF, but due to the high incidence of pruritus observed with topical captopril this medication is not recommended for the treatment of CAF.

Agreement between personally generated areas of quality of life concern and standard outcome measures in people with advanced cancer.

PURPOSE: People with advanced cancer experience different sequelae which have unique effects on quality of life (QOL). The patient-generated index (PGI) is a personalized measure that allows patients to nominate, rate, and value areas that have the most impact on QOL. Fatigue, pain, and aspects of physical function are among the top 10 areas with QOL impact. An area of validation that is lacking for the PGI is the extent to which spontaneously nominated areas of QOL that patients are concerned with, agree with ratings obtained from standard patient reported outcomes (PROs). METHODS: Data from 192 patients were used to compare ratings on fatigue, pain, and physical function obtained from PGI to those from standard outcome measures. RESULTS: Within one severity rating, agreement ranged from 32.1 to 76.9 % within the fatigue domain, 34.2 to 95.24 % for pain, and between 84.2 and 94.7 % for physical function. Of the 10 items where the PGI had the highest agreement, 7 came from the RAND-36. At the domain level, people nominating an area scored in the more impaired range on standard measures than people who did not. CONCLUSION: PGI gives comparable information as do standard measures. IMPLICATIONS FOR CANCER: PGI provides important information to guide clinical care of the patient and also produces a legitimate total score suitable for research.

Using a personalized measure (Patient Generated Index (PGI)) to identify what matters to people with cancer.

PURPOSES: Patient Generated Index (PGI) is designed to both ask and document quality of life (QOL) concerns. Its validity with respect to standard QOL measures has not been fully established for advanced cancer when QOL concerns predominate. The specific objective of this study is to identify, for people with advanced cancer, similarities and differences in ratings of global QOL between personalized and standard measures. METHODS: A total of 192 patients completed five QOL measures at study entry: PGI, generic measures (SF-6D, EQ-5D), and cancer-specific measures of QOL (McGill Quality of Life Questionnaire and Edmonton Symptoms Assessment Scale). Comparisons among total scores were compared using Generalized Estimating Equations (GEE). RESULTS: Patients voiced 114 areas of QOL concerns by the PGI with the top three being fatigue, sleep, and pain (39.2, 22.6, and 21.6%, respectively). PGI total QOL score was 25 to 30 percentage points lower than those documented by the other measures, particularly when QOL was poor. Correlations between PGI and other measures were low. CONCLUSION: PGI allowed patients to express a wide range of QOL concerns, many that were not assessed by other QOL measures. If only one QOL measure is to be included, either in a clinical setting or for research, the PGI would satisfy many of the criteria for "best choice." PGI could be considered a cancer-specific QOL measure. IMPLICATIONS FOR CANCER: This study provides evidence that the PGI would be a good measure for patients and clinicians to use together to identify areas of concern that require attention and monitor changing needs.

Effect of vitamin D on stress-induced hyperglycaemia and insulin resistance in critically ill patients.

AIM: Effects of vitamin D supplementation on the glycaemic indices and insulin resistance in diabetic and non-diabetic patients were studied. In this study, effects of vitamin D supplementation on stress-induced hyperglycaemia and insulin resistance were evaluated in non-diabetic surgical critically ill patients. METHODS: Adult surgical patients with stress-induced hyperglycaemia within the first 24 h of admission to the ICU were recruited. The patients randomly assigned to receive either vitamin D or placebo. Patients in the vitamin D group received a single dose of 600,000 IU vitamin D3 as intramuscular injection at time of recruitment. Besides demographic and clinical characteristics of the patients, plasma glucose, insulin, 25(OH) D and adiponectin levels were measured at the time of ICU admission and day 7. Homoeostasis model assessment for insulin resistance (HOMA-IR) and homestasis model assessment adiponectin (HOMA-AD) ratio were considered at the times of assessment. RESULTS: Comparing with the baseline, plasma 25(OH) D level significantly increased in the subjects who received vitamin D (p = 0.04). Improvement in fasting plasma glucose levels was detected in day 7 of the study compared with the baseline status in both groups. HOMA-IR showed a decrement pattern in vitamin D group (p = 0.09). Fasting plasma adiponectin levels increased significantly in the vitamin D group (p = 0.007), but not in the placebo group (p = 0.38). Finally, changes in HOMA-AD ratio were not significant in the both groups. CONCLUSION: Vitamin D supplementation showed positive effect on plasma adiponectin level, as a biomarker of insulin sensitivity in surgical critically ill patients with stress-induced hyperglycaemia. However, effects of vitamin D supplementation on HOMA-IR and HOMA-AD as indicators of insulin resistance were not significant.

Reevaluation of commercial reagents for detection of Histoplasma capsulatum antigen in urine.

Detection of the Histoplasma capsulatum urinary antigen (UAg) is among the most sensitive and rapid means to diagnose histoplasmosis. Previously, we evaluated analyte-specific reagents (ASR) manufactured by IMMY (Norman, OK) for detection of Histoplasma galactomannan (GM) in urine using an enzyme immunoassay (EIA), and we showed low positive agreement (64.5%) with the MiraVista (MVista) Histoplasma antigen (Ag) quantitative EIA (MiraVista Diagnostics, Indianapolis, IN). Here we reevaluated the IMMY GM ASR following modification of our original assay protocol and introduction of an indeterminate range. A total of 150 prospectively collected urine samples were tested with both the IMMY and MVista EIAs, and clinical histories were recorded for all study subjects. The IMMY GM ASR showed positive and negative agreements of 82.3% (14/17 samples) and 100% (121/121 samples), respectively (with exclusion of 12 indeterminate results), and overall agreement of 90% (135/150 samples) with respect to the MVista EIA. Of the three patients with negative IMMY GM ASR results and positive MVista EIA results, testing was performed for initial diagnostic purposes for one patient (<0.4 ng/ml by the MVista EIA) and UAg levels were being monitored for the remaining two patients (both<0.7 ng/ml by the MVista EIA). The MVista EIA results were positive for 6/12 samples that tested indeterminate by the IMMY GM ASR. We also show that the IMMY GM ASR can be used to serially monitor Histoplasma UAg levels. In conclusion, we demonstrate that, with modification, the IMMY GM ASR is a reliable rapid assay for detection of Histoplasma UAg.

Mechanisms contributing to low orthostatic tolerance in women: the influence of oestradiol.

The impact of 17ß-oestradiol (E2) exposure on autonomic control of orthostasis in young women is unclear. We tested the hypothesis that autonomic cardiovascular regulation is more sensitive to E2 exposure in women with low orthostatic tolerance. Women underwent an initial maximal lower body negative pressure (LBNP) test to place them into a low (LT, n = 7, 22 ± 1 years old, body mass index 22 ± 1 kg m(-2)) or a high orthostatic tolerance group (HT, n = 7, 22 ± 1 years old, body mass index 24 ± 1 kg m(-2)). We then suppressed endogenous reproductive hormone production using a gonadotrophin-releasing hormone antagonist (GnRHant) for 10 days, with E2 administration during the last 7 days of GnRHant. We measured R-R interval and beat-by-beat blood pressure during the modified Oxford protocol, and changes in heart rate, blood pressure and forearm vascular resistance (FVR) during submaximal LBNP. During submaximal LBNP, FVR increased in HT (ANOVA P < 0.05) but not in LT (ANOVA P > 0.05), and stroke volume was lower in LT relative to HT at all levels of LBNP (P < 0.05). Compared with GnRHant, E2 administration shifted FVR lower in LT (ANOVA P < 0.05), with no effect in HT. Administration of E2 increased baroreflex control of heart rate (derived from the modified Oxford protocol) in LT (GnRHant 10.7 ± 2.5 ms mmHg(-1) vs. E2 16.1 ± 2.4 ms mmHg(-1), P < 0.05) but not in HT (GnRHant 13.4 ± 1.9 ms mmHg(-1) vs. E2 15.3 ± 2.4 ms mmHg(-1), n.s.). In conclusion, blunted peripheral vasoconstriction and lower stroke volume contribute to compromised orthostatic tolerance in women; this inability to vasoconstrict is further exacerbated by exposure to E2. Furthermore, E2 administration increases baroreflex-mediated heart rate responses to orthostasis in low orthostatic tolerant women, which is likely to be a compensatory mechanism for the blunted peripheral vascular resistance and lower central volume.

A comparative study of beneficial effects of Olanzapine and sodium valproate on aggressive behavior of patients who are on methadone maintenance therapy: a randomized triple blind clinical trial.

BACKGROUND: Previous studies have shown a high prevalence of aggressive behavior in abstinent heroin users who are on methadone maintenance therapy (MMT) compared with healthy controls. Some studies suggest that olanzapine and valproate may be effective in managing aggressive behavior and preventing a relapse of substance misuse in patients on methadone regime. AIM: The aim of the present study was to evaluate and compare the effectiveness of these medications in the management of aggressive behavior and prevention of relapse in patients maintained on methadone. PATIENTS AND METHODS: Two hundred and one patients on MMT were randomized into two treatment groups of olanzapine (2.5-15 mg) and sodium valproate (600-1000 mg). Both groups were treated for 12 weeks. Patients visited the clinic twice weekly to receive medication. Patients' urine samples were screened for trace of any illicit substances on each visit. Upon each consultation, the clinicians, using overt aggression scale-modified version (OAS-M), assessed the degree and frequency of aggressiveness in each patient. RESULTS: Fifty three patients completed the trial. Both medications significantly reduced the overt aggression and subscales of irritability, aggression and suicidality. Improvement was more pronounced in the group treated with olanzapine. The mean percentages of positive urine samples for morphine, cannabis and methamphetamine abuse for the 12 weeks period of the study were not significantly different between the two groups. CONCLUSIONS: Both olanzapine and sodium valproate are useful as an adjunctive agent in reducing aggressive behavior in heroin dependent individuals who are on MMT, but the beneficial effect of olanzapine was greater than sodium valproate in this respect.  

Altered steering strategies for goal-directed locomotion in stroke.

BACKGROUND: Individuals who have sustained a stroke can manifest altered locomotor steering behaviors when exposed to optic flows expanding from different locations. Whether these alterations persist in the presence of a visible goal and whether they can be explained by the presence of a perceptuo-motor disorder remain unknown. The purpose of this study was to compare stroke participants and healthy participants on their ability to control heading while exposed to changing optic flows and target locations. METHODS: Ten participants with stroke (55.6 ± 9.3 yrs) and ten healthy controls (57.0 ± 11.5 yrs) participated in a mouse-driven steering task (perceptuo-motor task) while seated and in a walking steering task. In the seated steering task, participants were instructed to head or 'walk' toward a target in the virtual environment by using a mouse while wearing a helmet-mounted display (HMD). In the walking task, participants performed a similar steering task in the same virtual environment while walking overground at their comfortable speed. For both experiments, the target and/or the focus of expansion (FOE) of the optic flow shifted to the side (±20°) or remained centered. The main outcome measure was net heading errors (NHE). Secondary outcomes included mediolateral displacement, horizontal head orientation, and onsets of heading and head reorientation. RESULTS: In the walking steering task, the presence of FOE shifts modulated the extent and timing of mediolateral displacement and head rotation changes, as well as NHE magnitudes. Participants overshot and undershot their net heading, respectively, in response to ipsilateral and contralateral FOE and target shifts. Stroke participants made larger NHEs, especially when the FOE was shifted towards the non-paretic side. In the seated steering task, similar NHEs were observed between stroke and healthy participants. CONCLUSIONS: The findings highlight the fine coordination between rotational and translational steering mechanisms in presence of targets and FOE shifts. The altered performance of stroke participants in walking but not in the seated steering task suggests that an altered perceptuo-motor processing of optic flow is not a main contributing factor and that other stroke-related sensorimotor deficits are involved.

Primary Sarcomas of the Larynx: A Case Series of Four Different Histopathologic Types.

Primary laryngeal sarcomas are rare. Their nomenclature and classification are similar to soft tissue counterparts; however, there are notable differences between clinical presentation, behavior, treatment, and follow-up. There is sparse information regarding the clinical features, biologic behavior, and treatment modalities of laryngeal sarcomas. To increase our understanding about these tumors, we describe herein an additional series of four cases of different pathologic types of laryngeal sarcomas, including low-grade chondrosarcoma, leiomyosarcoma, well-differentiated liposarcoma, and undifferentiated pleomorphic sarcoma. Our main aim is to upsurge awareness about the morphologic variations of laryngeal sarcomas, to avoid potential pitfalls during histopathologic examination. It is essential to ensure that correct diagnosis, subclassification, and grading are achieved for proper guidance of treatment and clinical follow-up at multidisciplinary team meetings.

Circumstances and Factors Associated With Falls Among Community-Dwelling Older Adults Diagnosed With Heart Disease Using the International Mobility in Aging Study (IMIAS).

BACKGROUND AND PURPOSE: To identify the circumstances of falls and the factors associated with falls among older adults with cardiovascular disease (CVD). METHODS: Baseline (2012) data from the International Mobility in Aging Study (IMIAS), a cross-sectional study, were used. Falling was measured by the subjective question, "Have you fallen in the last 12 months?" Several subjective questions were asked to obtain information about the circumstances of falls. Potential clinical factors associated with falling were cognitive status, depressive symptoms, physical performance, grip strength, visual acuity, and fear of falling (FOF). These clinical factors were measured respectively with the Leganes Cognitive Test, the Center for Epidemiological Studies Scales Depressive Symptoms, the Short Physical Performance Battery, a Jamar handgrip dynamometer, the Early Treatment Diabetic Retinopathy Study (ETDRS) tumbling E chart placed at 2 m, and the Falls Efficacy Scale-International. A χ 2 test was used to determine whether there were significant differences in fall circumstances among older adults with and without CVD. Two-sample t tests were used to test for any significant differences between older adults with and without CVD. Bonferroni correction was applied to limit type I errors and was corrected to .007. Simple and multiple logistic regressions identified which clinical factors were associated with falling. RESULTS: A total of 429 older adults with CVD (mean age 69.5 ± 2.9) and 431 older adults without CVD (69.2 ± 2.9) participated in the study. Approximately 53% of fallers with CVD had 2 or more falls compared with fallers without CVD (39%). The most common location for falling was at home (43%) for fallers with CVD or in the street (50%) for fallers without CVD. Approximately 9% of fallers with CVD needed to be hospitalized while only 3% of fallers without CVD were admitted to the hospital. Approximately 42% of fallers with CVD had some residual sequelae (eg, being unable to walk around the house or do housework) compared with only 27% of fallers without CVD. Fallers with CVD had significantly ( P value < .007) more depressive symptoms (mean ± SD, 14.7 ± 12.9) and poorer physical performance (8.4 ± 3.0) compared with fallers without CVD (10.1 ± 9.4 and 9.6 ± 2.5, respectively); however FOF was the only significant clinical factor ( P value < .05) associated with falling for older adults with CVD. CONCLUSIONS: Incidence of recurrent falls is higher among older adults with CVD than those without CVD. Circumstances of falls among fallers with CVD differ from those identified among fallers without CVD. Fear of falling was the only predictor of fall history among older adults with CVD. The results suggest the merit of considering FOF when designing prevention and intervention programs to reduce falls among older adults with CVD.

Cognitive status and sleep quality can explain the fear of falling and fall history in people with Parkinson's disease.

Fear of falling (FOF) is highly prevalent in people with Parkinson's disease (PwPD) and contributes to high fall risk. Studies reporting on the relationship between falls, FOF, and non-motor factors such as cognitive function and sleep quality in Parkinson's disease are limited. This study aimed to investigate (1) the relationship of cognitive function and sleep quality with FOF, and history of falls in PwPD; (2) differences in cognitive function and sleep quality between Parkinson's disease fallers and non-fallers; and (3) a cut-off score for cognitive function and sleep quality to discriminate Parkinson's disease fallers from non-fallers. Fifty PwPD were assessed for FOF [Falls Efficacy Scale-International (FES-I)], cognition [Montréal Cognitive Assessment (MOCA)], sleep quality [Pittsburgh Sleep Quality Index (PSQI)], and falls history. The MOCA is significantly associated with FES-I scores ( R2  = 0.429, P  < 0.0001). Both MOCA ( P  = 0.012) and PSQI ( P  = 0.027) were associated with falls history even after adjusting for confounding factors (age, sex, L-dopa use, Parkinson's disease severity). Both MOCA and PSQI scores were able to distinguish fallers from non-fallers with cut-off scores of 15.5 and 7.5, respectively. Although our findings revealed that both cognitive function and sleep quality are important factors influencing falls and FOF in PwPD, it remains to be determined if addressing cognitive impairments and poor sleep quality may favorably impact balance before integrating such screenings into fall prevention programs.

Exercise capacity in people with Parkinson's disease: which clinical characteristics are important?

BACKGROUND: People with Parkinson's (PwP) are suffering from reduced exercise capacity. However, little information is known about clinical correlates of exercise capacity in this population. OBJECTIVE: This study aimed to evaluate correlations between motor and non-motor symptoms with exercise capacity in PwP. METHODS: A total of 50 individuals with Parkinson's disease participated in the study. Exercise capacity was measured by 6 minutes' walk test (6MWT). Besides, the Movement Disorder Society-Unified Parkinson's Disease Rating Scale-Part III used to evaluate disease motor severity, Berg Balance Scale to assess balance, Montréal Cognitive Assessment to evaluate cognitive status, hospital anxiety and depression scale to assess depression and anxiety, Modified Fatigue Impact scale to evaluate fatigue, and the Pittsburgh Sleep Quality Index to evaluate sleep quality. RESULTS: The results showed that exercise capacity, when measured by the 6MWT, can be significantly predicted by balance, disease motor severity, anxiety, and age (R2 = 0.61 P < .0001). CONCLUSION: These results suggest that exercise capacity in PwP is multifactorial and can potentially be predicted by balance, motor severity, anxiety, and age.

Fear of Falling Among Community-Dwelling Older Adults with Heart Disease: Findings from an International Mobility in Aging Study (IMIAS).

BACKGROUND: Older adults with heart disease (HD) are more likely to report a higher prevalence of falls compared to those without HD. A knowledge gap currently exists regarding the factors associated with fear of falling (FOF) among older adults with HD. Therefore, this study aimed to estimate FOF and identify factors associated with FOF among older adults with HD. METHODS: Data came from a secondary analysis of the International Mobility in Aging Study (IMIAS) baseline (2012) data. FOF was measured using the Falls Efficacy Scale-International (FES-I). Stepwise linear regression was used to identify factors associated with FOF. RESULTS: A total of 429 participants identified themselves as having heart disease diagnosed by their physician (mean age 69.5 ± 2.9). Older adults with HD reported on average (25.6) higher FOF than those without HD. For older adults with HD, FES-I increased significantly by 1.3, 1.0, and 0.6 points, when the Short Physical Performance Battery, the Leganes Cognitive Test, and QOL total scores decreased by one point. FES-I also significantly increased by 3.2 when income was insufficient compared to sufficient or very sufficient income. DISCUSSION: FOF is multifactorial, and our findings provide a base for developing future management rehabilitation intervention programs aimed at decreasing FOF among older adults with HD.

Physiotherapists' knowledge, perception, and attitude regarding COVID-19 and infection control: An online cross-sectional survey in Jordan.

BACKGROUND: The COVID-19 pandemic highlighted the importance of knowledge and awareness of healthcare practitioners regarding infection control. OBJECTIVE: To explore Jordanian physiotherapists' knowledge and perception of COVID-19, awareness about protection measures, and attitude towards infection prevention. METHODS: A cross-sectional online survey was used. Data were collected from licensed physiotherapists currently living in Jordan. A structured survey was used to collect the data consisting of five parts: 1) General information about the physiotherapists including sociodemographic, academic training, and employment setting, 2) General knowledge about COVID-19, 3) Infection protection in the workplace, 4) Perception of COVID-19, and 5) Attitude towards COVID-19 in daily life and during work. RESULTS: A total of 147 physiotherapists completed the survey with a mean age of 30.56 (7.70) and years of experience of 7.28 (7.21). The mean of the total knowledge score was 17.18 (2.32)/ 26. There was a significant difference in the total knowledge score between COVID-19 trained physiotherapists and untrained (t = 2.895, p = 0.004). About 70.8% of the physiotherapists perceived COVID-19 as a very dangerous disease, 69.4% considered physiotherapy a high-risk profession, and 41% perceived COVID-19 does not require any special treatment. Approximately 85% of physiotherapists avoided going to crowded places and wore a mask when leaving home. 75-86.6% of physiotherapists would consider appropriate protective measures during their work. CONCLUSIONS: Physiotherapists showed suboptimal knowledge, perception, and attitude towards COVID-19. There is a need for training courses to increase physiotherapists' knowledge about COVID-19 and improve their perception and attitude towards COVID-19.

Clinical Ethics from the Islamic Perspective : A qualitative study exploring the views of Jordanian doctors.

Like other Arab countries, Jordan must find ways of responding to the rapid processes of change affecting many aspects of social life. This is particularly urgent in healthcare, where social and technical change is often manifested in tensions about ethical decision-making in the clinic. To explore the attitudes, beliefs and concerns relating to ethical decision-making among health professionals in Jordanian hospitals, a qualitative study was conducted involving face-to-face interviews with medical personnel in four hospitals in Amman, the capital of Jordan. Data were analysed thematically in relation to a pre-existing set of ethical categories. Interviews were conducted with thirty-eight doctors covering most medical specialities. Five major themes emerged from the interviews: ethical awareness, ethical issues, the impact of religion on ethical decision-making, practical and theoretical resources for ethical decision-making, and challenges. While uncertainty was expressed about some aspects of Western approaches to ethics, participants strongly supported adoption of a range of Western bioethical principles, including cultural and ethical diversity, along with adherence to Islamic religious norms. A range of serious ethical challenges facing the Jordanian health system were identified, covering social, legal, managerial, and technical issues. Ethical decision-making in Jordan is complex, having to accommodate the needs of patients, the opinions of doctors and their families, the views of religious authorities, managerial considerations, and both local norms and international standards. Health professionals struggle with three sets of tensions that emerge out of the struggle between traditional, community-embedded forms of social organization and the demands generated by globalization and the influence of Western culture: the tensions between tradition and modernity, conservatism and pragmatism, and religion and secularism. Doctors in Jordan prefer approaches to ethical decision-making that realize a balance between the extremes, although the exact nature of where that balance should lie remains uncertain.
