Facilitating and hindering factors for routine adaptations in manufacturing and effects on human performance- unexpected insights from three experimental studies in a special purpose setting

Consumer behaviour changes and strategic management decisions are driving adaptations in manufacturing routines. Based on the theory of situational strength, we investigated how contextual and person-related factors influence workers’ adaptation in a two-worker position routine. Contextual factors, like retrieval cues (Study 1), time pressure (Study 2), and convenience (Study 3), were varied. Person-related factors included retentivity, general and routine-specific self-efficacy, and perceived adaptation costs. Dependent variables included various error types and production time before and after adaptation. In each study, 148 participants were trained in a production routine at t1 and executed an adapted routine at t2, one week later. Repeated measures ANOVA for performance at t1 and t2, and MANOVA for performance at t2, revealed that time increased for all groups at t2. For participants in Studies 1 & 2, error rates remained consistent. Retentivity significantly impacted errors at both t1 and t2, emphasising that routine changes in a ‘running business’ take time, regardless of contextual factors. Workers with lower retentivity may require additional support.

Deprescribing NSAIDs: The Potential Role of Community Pharmacists

Non-steroidal anti-inflammatory drugs (NSAIDs) are largely used for controlling various pain conditions and are widely available in community pharmacies, with and without prescription. Despite their effectiveness, NSAIDs can pose significant risks due to potential side effects and drug interactions, particularly in polypharmacy and comorbidity contexts and for vulnerable users. This study investigated whether and how NSAID deprescribing can be conducted at the community pharmacy level by assessing pharmacists’ confidence, attitudes, and potential barriers and facilitators. Additionally, we aimed to identify any deprescribing guidelines that pharmacists could use. A literature search and a cross-sectional digital questionnaire targeting community pharmacists in Norway were conducted. Results showed that study participants (N = 73) feel confident in identifying needs for deprescribing NSAIDs but barriers such as time constraints, lack of financial compensation, and communication challenges were noted. Participants reported positive attitudes toward deprescribing but highlighted a need for better guidelines and training. This study highlights a gap in specific guidelines for deprescribing NSAIDs and a potential for enhancing pharmacists’ roles in the deprescribing process, for example, through training and improved financial incentives. Further research is encouraged to develop concrete strategies for an effective implementation where community pharmacists can be involved in the deprescribing of NSAIDs.

Analysis of macular thickness and peripapillary retinal nerve fiber layer thickness in various ABO and Rh blood groups

PurposeTo determine the association between ABO and Rh blood groups with retinal structural indices including macular thickness and peripapillary retinal nerve fiber layer (RNFL) thickness.MethodsThis cross-sectional study was conducted using convenience sampling in a tertiary referral eye hospital in Tehran, Iran. Study participants were referred to the hospital laboratory to test their blood group. Ocular examinations were performed including measurement of visual acuity, auto-refraction, subjective refraction, and slit-lamp biomicroscopy. Retinal imaging was carried out using Spectral-domain OCT under dilated papillary conditions.ResultsThree hundred and twenty-eight individuals were recruited in this study. Of these, 219 (60.7%) were female and the mean age of the participants was 63.29 ± 5.57 years (range: 56 to 83 years). According to the multiple linear regression model, the global peripapillary RNFL thickness [coefficient: -3.05 (95% CI: -5.30 to -0.74); P = 0.010] and peripapillary RNFL thickness in the superior [coefficient: -4.65 (95% CI: -8.40 to -0.89), P < 0.001] and inferior [coefficient: -4.00 (95% CI: -7.81 to -0.19); P = 0.040] quadrants were significantly thinner in individuals with blood type B compared to those with other ABO blood groups. The average [coefficient: 12.69 (95% CI: 4.12–21.64); P = 0.004) and central [coefficient: 16.21 (95%: 6.44–25.97); P = 0.001) macular thicknesses were significantly thicker in AB group compared to other blood groups. The average macular thickness was significantly thinner in Rh + compared to the Rh- group [coefficient: -8.33 (95% CI: -15.4 to -1.25); P = 0.021].ConclusionRetinal structural indices may be related to blood groups implying a genetic linkage. Considering the lack of consistency among various studies, larger trials are needed to explore the effect of ABO and Rh grouping on peripapillary RNFL and macular thicknesses.

Early Burst Suppression Similarity Association with Structural Brain Injury Severity on MRI After Cardiac Arrest.

Identical bursts on electroencephalography (EEG) are considered a specific predictor of poor outcomes in cardiac arrest, but its relationship with structural brain injury severity on magnetic resonance imaging (MRI) is not known. This was a retrospective analysis of clinical, EEG, and MRI data from adult comatose patients after cardiac arrest. Burst similarity in first 72h from the time of return of spontaneous circulation were calculated using dynamic time-warping (DTW) for bursts of equal (i.e., 500ms) and varying (i.e., 100-500ms) lengths and cross-correlation for bursts of equal lengths. Structural brain injury severity was measured using whole brain mean apparent diffusion coefficient (ADC) on MRI. Pearson's correlation coefficients were calculated between mean burst similarity across consecutive 12-24-h time blocks and mean whole brain ADC values. Good outcome was defined as Cerebral Performance Category of 1-2 (i.e., independence for activities of daily living) at the time of hospital discharge. Of 113 patients with cardiac arrest, 45 patients had burst suppression (mean cardiac arrest to MRI time 4.3days). Three study participants with burst suppression had a good outcome. Burst similarity calculated using DTW with bursts of varying lengths was correlated with mean ADC value in the first 36h after cardiac arrest: Pearson's r: 0-12h: -0.69 (p = 0.039), 12-24h: - 0.54 (p = 0.002), 24-36h: - 0.41 (p = 0.049). Burst similarity measured with bursts of equal lengths was not associated with mean ADC value with cross-correlation or DTW, except for DTW at 60-72h (- 0.96, p = 0.04). Burst similarity on EEG after cardiac arrest may be associated with acute brain injury severity on MRI. This association was time dependent when measured using DTW.

Evaluating Changes in Adult Cochlear Implant Users' Brain and Behavior Following Auditory Training.

To describe the effects of two types of auditory training on both behavioral and physiological measures of auditory function in cochlear implant (CI) users, and to examine whether a relationship exists between the behavioral and objective outcome measures. This study involved two experiments, both of which used a within-subject design. Outcome measures included behavioral and cortical electrophysiological measures of auditory processing. In Experiment I, 8 CI users participated in a music-based auditory training. The training program included both short training sessions completed in the laboratory as well as a set of 12 training sessions that participants completed at home over the course of a month. As part of the training program, study participants listened to a range of different musical stimuli and were asked to discriminate stimuli that differed in pitch or timbre and to identify melodic changes. Performance was assessed before training and at three intervals during and after training was completed. In Experiment II, 20 CI users participated in a more focused auditory training task: the detection of spectral ripple modulation depth. Training consisted of a single 40-minute session that took place in the laboratory under the supervision of the investigators. Behavioral and physiologic measures of spectral ripple modulation depth detection were obtained immediately pre- and post-training. Data from both experiments were analyzed using mixed linear regressions, paired t tests, correlations, and descriptive statistics. In Experiment I, there was a significant improvement in behavioral measures of pitch discrimination after the study participants completed the laboratory and home-based training sessions. There was no significant effect of training on electrophysiologic measures of the auditory N1-P2 onset response and acoustic change complex (ACC). There were no significant relationships between electrophysiologic measures and behavioral outcomes after the month-long training. In Experiment II, there was no significant effect of training on the ACC, although there was a small but significant improvement in behavioral spectral ripple modulation depth thresholds after the short-term training. This study demonstrates that auditory training improves spectral cue perception in CI users, with significant perceptual gains observed despite cortical electrophysiological responses like the ACC not reliably predicting training benefits across short- and long-term interventions. Future research should further explore individual factors that may lead to greater benefit from auditory training, in addition to optimization of training protocols and outcome measures, as well as demonstrate the generalizability of these findings.

Salmonella Typhi genotypic diversity, cluster identification and antimicrobial resistance determinants in Mukuru settlement, Nairobi Kenya

BackgroundUnderstanding the source of typhoid infections and the genetic relatedness of Salmonella Typhi (S. Typhi) by cluster identification in endemic settings is critical for establishing coordinated public health responses for typhoid fever management. This study investigated the genotypic diversity, antibiotic resistance mechanisms, and clustering of 35 S.Typhi strains isolated from cases and carriers in the Mukuru Informal Settlement.MethodsWe studied 35 S.Typhi isolates, including 32 from cases and 3 from carriers, from study participants in the informal settlement of Mukuru, Nairobi, Kenya. Genomic DNA was extracted, and whole-genome sequencing (WGS) was performed to determine the phylogenetic relatedness of strains and detect antimicrobial resistance determinants (AMR). WGS data were analyzed using bioinformatics tools available at the Center for Genomic Epidemiology and Pathogenwatch platforms.ResultsGenotype 4.3.1.2 EA3 was found to be dominant at 46% (16/35), followed by 4.3.1.2 EA2 at 28% (10/35), and 4.3.1.1 EA1 at 27% (9/35). A comparison of the isolates with global strains from Pathogenwatch identified close clustering with strains from Uganda, Tanzania, Rwanda, and India. Three isolates (9%) distributed in each cluster were isolated from carriers. All genotype 4.3.1.2 EA3 isolates were genotypically multidrug-resistant to ampicillin, chloramphenicol, and trimethoprim-sulfamethoxazole. Single mutations in the quinolone resistance-determining region were identified in the gyrA (S83Y) and gyrB (S464F) genes. All isolates associated with multidrug resistance showed the presence of the IncQ1 plasmid with the following genes: blaTEM-1B, catA1, sul1, sul2, and dfrA7.ConclusionThe close phylogenetic relatedness between antimicrobial-resistant case isolates and carriage isolates indicates that typhoid carriage is a possible source of infection in the community. Comparative analysis with global isolates revealed that the Kenyan isolates share common lineages with strains from neighboring East African countries and India, suggesting regional dissemination of specific MDR clones. AMR was a major feature of the isolates. Surveillance and testing for antimicrobial susceptibility should inform options for the management of cases.

Clinical characteristics of pediatric patients hospitalized with community-acquired pneumonia and cytomegalovirus DNA detected in bronchoalveolar lavage fluid.

This study aimed to investigate the clinical characteristics of pediatric patients hospitalized with community-acquired pneumonia (CAP) and concomitant cytomegalovirus (CMV) infection. This cross-sectional study enrolled consecutive pediatric patients admitted with CAP who tested positive for CMV DNA in bronchoalveolar lavage fluid (BALF). Flexible fiberoptic bronchoscopy was performed when routine treatment for CAP proved ineffective. The study participants were further stratified into two groups based on CMV serological test results: recent CMV infection group and CMV replication group. Clinical characteristics were compared between these two groups. Among 124 patients aged 1-11 months included in this study, 80 (64.5%) patients were categorized as having recent CMV infection, and 44 (35.5%) tested positive for CMV replication. Co-infection with other pathogens was detected more frequently in the CMV replication group (n = 29, 65.9%) than in the recent CMV infection group (n = 35, 43.7%; P = 0.018). Patients with recent CMV infection were younger and exhibited higher levels of alanine transaminase (ALT) and aspartate aminotransferase compared to those with CMV replication (all P < 0.05). Multivariable regression analysis showed age was independently associated with recent CMV infection (odds ratio [OR], 0.707; 95% confidence interval [CI], 0.586-0.853; P < 0.001). Notably, receiver operating characteristic curve analysis showed that a CMV PCR level of 3,840 copies/ml in blood samples had a sensitivity of 34.7% and specificity of 90.0% for diagnosis of recent CMV infection with an area under the curve (AUC) of 0.625 (95% CI: 0.513-0.736, P = 0.048). A CMV PCR level of 6,375 copies/ml in urine samples had a sensitivity of 77.1% and specificity of 61.5% for diagnosis of recent CMV infection with an AUC of 0.695 (95% CI: 0.531-0.858, P = 0.04). Furthermore, multivariate linear regression analysis revealed that the blood CMV DNA copy number was associated with ALT (B = 0.001; P < 0.001). The CMV DNA copy numbers in blood and urine could serve as discriminatory markers between recent CMV infection and CMV replication. Measuring CMV DNA levels in blood may be an effective method for monitoring liver function impairment in pediatric patients presenting with CAP and concurrent CMV infection.

Reliability and Validity of the Global Physical Activity Questionnaire for Portuguese Adults.

The Global Physical Activity Questionnaire (GPAQ) has been used often to assess physical activity (PA) patterns. However, the European Portuguese version of this instrument has not been validated. We aimed to validate the self-administered GPAQ, version 2, (GPAQv2) for Portuguese adults. We included 32 participants in a pilot study of a Portuguese adaptation of the test and 108 participants in an assessment of their PA patterns and sedentary behavior (SB) through the GPAQv2. For its validation, we compared the GPAQv2 to the International PA Questionnaire-Long Form (IPAQ-LF) (concurrent validity) and the ActiGraph wGT3X-BT accelerometer (criterion validity). We evaluated PA and SB at baseline and after seven consecutive days. Test-retest reliability with the Kappa test (k) and the Intraclass Correlation Coefficient (ICC) ranged from strong to almost perfect (k: 0.864-0.976) and from moderate to excellent (ICC: 0.56-0.994), respectively. Concurrent validity, assessed by Spearman's Correlation Coefficient, was moderate to substantial (rho: 0.471-0.680), and there was fair to substantial criterion validity (rho: 0.226-0.672). Bland-Altman plots showed that the GPAQv2 overestimated vigorous and moderate to vigorous PA and underestimated moderate PA. The largest difference values were related to SB, since the GPAQv2 underestimated sitting time. In sum, we found the GPAQv2 to have acceptable validity and reliability for assessing PA and SB patterns, and we recommend its use for Portuguese adults.

A novel polyp retrieval bag reduces the polyp fragmentation rate in colon polypectomy: a single-blind randomized controlled study

PurposeThe fragmentation of polyps affects complete resection confirmation. The primary aim of this study was to assess the feasibility of a novel polyp retrieval bag for reducing the fragmentation rate of colon polyps.MethodsPatients with a 5–15 mm colon polyp were recruited and randomized into two groups at a 1:1 ratio. After polyp resection, polyps obtained from patients in the treatment group were extracted via a novel polyp retrieval bag without traversing the instrument channel, whereas polyps obtained from patients in the control group were collected through the instrument channel, attaching the polyp trap to the instrument channel port, and applying suction.ResultsFrom January to July 2022, 225 patients were assessed for eligibility. The study participants included 204 patients, and seven patients whose samples were not retrieved were excluded. Polyp fragmentation was significantly lower in the treatment group than in the control group (3.0% [3/100] vs. 17.5% [17/97], P = 0.001). The retrieval failure rates in the treatment group and control group were not significantly different (2.0% [2/102] vs. 4.9% [5/102], P = 0.442). There were fewer colonoscope insertions in the treatment group than in the control group (102 vs. 110), but a significant difference was not present (P = 0.065). No significant adverse events were observed during the follow-up.ConclusionsThis study demonstrated that the polyp retrieval bag was safe and feasible for reducing the fragmentation rate of retrieved polyps.Trial registrationThe study was registered at ClinicalTrials.gov (NCT05189912, 1/12/2021).

Effects of Nutritional Status and Foods Consumed on Inflammation and Disease Activity in Patients with Rheumatoid Arthritis

Background and Objectives: This study investigated the impact of nutritional status and foods consumed on inflammation and disease activity in patients with rheumatoid arthritis (RA). Materials and Methods: We designed a cross-sectional observational study, involving 110 patients diagnosed with RA. The patients included were between 18 and 75 years old, diagnosed with rheumatoid arthritis two years ago or earlier, with stable treatment for the last 8 weeks. Data on anthropometric parameters, body mass composition, nutritional status, individual food consumption records, inflammation, disease activity, quality of life, clinical, and laboratory parameters were collected for each study participant. The evaluation parameters of the patients were the simple disease activity index (SDAI), clinical disease activity index (CDAI), systemic immune-inflammation index (SII) and individual food consumption records. A bioimpedance device and measuring tape were used to take body composition and anthropometric measurements of the patients. Results: According to the body mass index, waist circumference and waist-to-height ratio, in our study, we found that 60% of the patients were obese, 80% were at a very high health risk, and approximately 91% were in need of nutritional treatment. There was a significant negative correlation between the dietary intake of total energy, total fat, omega 3, calcium, zinc, cobalamin and the disease activity (SDAI, CDAI). There was a significant negative correlation between polyunsaturated fatty acids, omega 3, carotene, vitamin E, selenium and the SII. Additionally, there was a positive correlation between omega 6 and the SII, SDAI, CDAI (p &lt; 0.05). Conclusions: The results of this study show that the foods consumed in the nutrition of RA patients may have effects on their inflammation and disease activity.

Longitudinal Phospho-tau217 Predicts Amyloid Positron Emission Tomography in Asymptomatic Alzheimer’s Disease

BackgroundBlood-based AD biomarkers such as plasma P-tau217 are increasingly used in clinical trials as a screening tool.ObjectivesTo assess the utility of an electrochemiluminescence (ECL) immunoassay in predicting brain amyloid PET status in cognitively unimpaired individuals.SettingPlasma samples collected at baseline, week 12, and week 240 or endpoint originated from the Anti-Amyloid Treatment in Asymptomatic Alzheimer’s Disease (A4) trial and the companion Longitudinal Evaluation of Amyloid Risk and Neurodegeneration (LEARN) study.ParticipantsBoth A4 and LEARN enrolled eligible cognitively unimpaired persons 65 to 85 years. Individuals with elevated brain amyloid PET levels were eligible for the A4 Study, while those without elevated brain amyloid PET levels were eligible for the LEARN Study.InterventionParticipants in the A4 Study received intravenous solanezumab (up to 1600 mg) or placebo every 4 weeks. The LEARN Study is an observational study without intervention.MeasurementsPlasma P-tau217 concentration levels from A4 Study participants were measured using an ECL immunoassay. Receiver Operating Characteristic (ROC) curve analysis was performed for each biomarker against amyloid positivity, defined by ≥22 CL and ≥ 33 CL.ResultsReceiver operating characteristic curve (ROC) analysis indicates high diagnostic value of P-tau217 in individuals with amyloid PET ≥ 20 (Area under the ROC (AUROC): 0.87) and ≥ 33 CL (AUROC: 0.89). Repeated testing with the placebo group taken 12 weeks apart (range: 68 to 143 days) and the LEARN participants taken between 1.4 and 1.75 years resulted in a strong positive correlation (Corr. 0.91 (0.90 to 0.92)).ConclusionAn ECL immunoassay testing plasma P-tau217 accurately predicts amyloid PET positivity in cognitively unimpaired individuals. Our future analyses aim to determine if use of this assay may reduce the screening burden of preclinical individuals into anti-amyloid clinical trials.

A pilot study in narrative approach of an adolescent parenting program for enhancing parenting competency during the COVID-19 pandemic in Hong Kong

ABSTRACT Since 2019, Hong Kong has been experiencing a social and mental health crisis caused by social unrest and the COVID-19 Pandemic. As a result, there have been reports of increasing family conflicts among secondary students. With the understanding that family support and positive relationships are crucial for maintaining the mental well-being of young people, narrative therapy is a practical approach for helping families shift from problem-focused perspectives to empowering strategies for rebuilding positive relationships. The study aims to report on the effectiveness of a pilot group parent narrative therapy workshop for family relationship harmonisation and enhancing parenting competency using quantitative and qualitative methods. The study participants included 34 parents from five local schools. The results indicated a significantly increased sense of parental competency, general self-efficacy, adult hope, and decreased parental stress. Qualitative reports and participants’ narratives also demonstrated the positive effect of the narrative therapy workshop on their parent–adolescent relationships.

Dietary diversity, undernutrition, and predictors among pregnant adolescents and young women attending Gulu University teaching hospitals in northern Uganda.

Undernutrition has deleterious consequences to both the mother and the unborn child, significantly contributing to maternal and neonatal morbidity and mortality. We assessed dietary diversity, the prevalence, and predictors of undernutrition among pregnant adolescents and young women (PAYW) attending antenatal clinic (ANC) at two large teaching hospitals in northern Uganda. Between 12th June 2023 to 27th October 2023, we conducted a facility-based, cross-sectional study at Gulu Regional Referral Hospital (GRRH) and St Mary's Hospital Lacor (SMHL), both in Gulu district, Uganda. We recruited PAYW aged 15-24 years attending ANCs. Sociodemographic and clinical characteristics of the study participants were collected using a pre-tested, semi-structured questionnaire. Undernutrition was defined as a mid-upper arm circumference (MUAC) of < 23 cm. Modified Poisson regression analysis was performed to determine factors independently associated with undernutrition. Data analyses was performed using STATA version 17.0. A p<0.05 was considered statistically significant. A total of 324 participants, with a mean age of 21.2±2.2 years were enrolled. About 62.0% (n = 201) of the participants dewormed during pregnancy. The prevalence of undernutrition was 12.7% [n = 41]. Prevalence was higher among participants who maintained pre-pregnancy diet (adjusted prevalence ratio [aPR] = 2.27, 95% Confidence Interval [CI]: 1.26-4.05, p = 0.006), those who did not receive nutritional education (aPR = 2.25, 95% CI: 1.21-4.20, p = 0.011) and consumption of non-green leafy vegetables (aPR = 4.62 95% CI: 1.64-13.01, p = 0.004). The prevalence of undernutrition was lower among participants who consumed milk and milk products (aPR = 0.44 95% CI: 0.24-0.81, p = 0.009) and among those who consumed fish and seafood compared to those who did not (aPR = 0.45 95% CI: 0.20-1.00, p = 0.050). About 1 in 8 of PAYW attending GRRH or SMHL had undernutrition, particularly those who lacked education about feeding habits during pregnancy and limited access to milk and milk products, fish and seafoods. We recommend health workers to offer timely education of pregnant adolescent and young women mothers about good feeding habits during pregnancy, appropriate monitoring of weight gain and physiological changes during pregnancy.

Patterns, outcomes, and preventability of clinically manifest drug-drug interactions in older outpatients: a subgroup analysis from a 6-year-long observational study in North India.

Older adults are vulnerable to adverse drug reactions (ADRs) and drug-drug interactions (DDIs). Evidence on clinically manifest DDIs in older outpatients is scanty. The present study aims to report clinically manifest DDIs, their risk factors, and preventive measures. A subgroup analysis of a 6-year (2015-2021) long prospective study was conducted in a tertiary hospital in North India. Older outpatients with ADRs constituted the study participants. Among 933 ADRs reported in 10,400 patient registrations, clinically manifest DDIs were involved in 199 (21.3%). DDIs accounted for 29.9%, 26.5%, and 21.3% of drug-related metabolic, vascular, and nervous system disorders, respectively. Movement disorders (n = 18), hypotension (n = 16), and hypoglycemia (n = 15) were the most common manifestations. Eighty-six percent of DDIs were of the pharmacodynamic type, and 13.1% were immune-mediated. Around 35% of DDIs resulted in hospitalization, with hyponatremia, movement disorder, and renal impairment as the common reasons. Older adults with Parkinsonism, infection, coronary artery disease, neuropsychiatric disease, and diabetes mellitus, respectively, had 3.28, 2.85, 1.97, 1.76, and 1.80 times higher odds of DDIs. Those receiving ≥ 10 drugs had 5.31 times higher odds of DDIs compared to individuals receiving 1-4 drugs. "Avoiding the causative drug," "optimal monitoring of the patient," and "start-low and go-slow" policy together could prevent 85% of DDIs. In conclusion,every fifth case of ADRs and nearly one third of ADR-related hospitalizations in older adults are related to DDIs. Movement disorder, hypotension, and hypoglycemia are the common manifestations. A holistic approach with drug omission, optimal patient monitoring, and slow titration of therapy can prevent significant DDIs in older adults.

Agreement Between Apple Watch and Actical Step Counts in a Community Setting: Cross-Sectional Investigation From the Framingham Heart Study.

Step counting is comparable among many research-grade and consumer-grade accelerometers in laboratory settings. The purpose of this study was to compare the agreement between Actical and Apple Watch step-counting in a community setting. Among Third Generation Framingham Heart Study participants (N=3486), we examined the agreement of step-counting between those who wore a consumer-grade accelerometer (Apple Watch Series 0) and a research-grade accelerometer (Actical) on the same days. Secondarily, we examined the agreement during each hour when both devices were worn to account for differences in wear time between devices. We studied 523 participants (n=3223 person-days, mean age 51.7, SD 8.9 years; women: n=298, 57.0%). Between devices, we observed modest correlation (intraclass correlation [ICC] 0.56, 95% CI 0.54-0.59), poor continuous agreement (29.7%, n=957 of days having steps counts with ≤15% difference), a mean difference of 499 steps per day higher count by Actical, and wide limits of agreement, roughly ±9000 steps per day. However, devices showed stronger agreement in identifying who meets various steps per day thresholds (eg, at 8000 steps per day, kappa coefficient=0.49), for which devices were concordant for 74.8% (n=391) of participants. In secondary analyses, in the hours during which both devices were worn (n=456 participants, n=18,760 person-hours), the correlation was much stronger (ICC 0.86, 95% CI 0.85-0.86), but continuous agreement remained poor (27.3%, n=5115 of hours having step counts with ≤15% difference) between devices and was slightly worse for those with mobility limitations or obesity. Our investigation suggests poor overall agreement between steps counted by the Actical device and those counted by the Apple Watch device, with stronger agreement in discriminating who meets certain step thresholds. The impact of these challenges may be minimized if accelerometers are used by individuals to determine whether they are meeting physical activity guidelines or tracking step counts. It is also possible that some of the limitations of these older accelerometers may be improved in newer devices.

Clinical evolution of patients with lower extremity peripheral artery disease during the COVID-19 pandemic (the COVID-PAD study).

Background: The COVID-19 pandemic has led to significant disruptions in chronic disease care and forced people to stay at home. The effects of such issues on outpatients with lower extremity peripheral artery disease (PAD) remain unknown. Patients and methods: Single-centre, retrospective-prospective study conducted in a Swiss University Hospital. Patients with PAD were included between May 1 and July 31, 2020, with a follow-up visit at 12 months. Upon both visits, the Leriche-Fontaine PAD stage was recorded, and study participants underwent ankle-brachial index (ABI) calculation to assess limb perfusion. Functional capacities were assessed through the 6-minute walking and treadmill tests. Major adverse cardiovascular (MACE) and limb events (MALE) were recorded. Data collected during the pandemic were compared with the pre-pandemic period (January 1, 2019-April 30, 2020). Results: Overall, 259 patients were included. Mean age was 69 years and male sex was prevalent (69.1%). Odds of experiencing a degradation in PAD stage were lower during the pandemic than before (odds ratio [OR]: 0.43; 95% confidence interval [CI]: 0.21-0.87; p = 0.018). No significant difference was found between periods in terms of ABI trends. Both pain-free walking time at treadmill test (p = 0.003) and maximal pain intensity at 6-minute walking test (p = 0.001) significantly improved during the pandemic. Compared with the pre-pandemic period, during the pandemic patients were hospitalized less frequently (p = 0.028) and were less likely to undergo elective limb revascularization (p<0.001). No significant difference was found between periods in terms of MALE (p = 0.311), whereas non-fatal strokes were less frequently reported during the pandemic (p = 0.043). Conclusion: In a cohort of outpatients with PAD, we found no evidence of clinical deterioration during the pandemic compared with the pre-pandemic period, though rates of adverse events were nonnegligible in both periods. In case of future pandemics, patients with PAD should be encouraged to maintain an active lifestyle while being closely monitored to avoid clinical worsening.

Health-related quality of life and its associated factors among infertile women compared with fertile women in public hospital Addis Ababa, Ethiopia: a comparative cross-sectional study

BackgroundInfertility can have detrimental physical, psychological, and social effects that significantly impact health-related quality of life. Although the impact of infertility on quality of life is well established, there is a lack of research comparing the quality of life between fertile and infertile women in Ethiopia.MethodsA hospital-based comparative cross-sectional study was conducted among 287 infertile and 301 fertile women. Participants were selected using systematic random sampling. A structured, validated tool was used to collect data. An independent sample t-test was conducted to determine if there was a difference in the study participants' quality of life domains and the mean total quality of life score. Multiple linear regressions were used to correlate quality of life scores with significant predictor factors for the infertile group.ResultsInfertile women had a mean total Herbal of 66.54 ± 10.18, and fertile women (72.68 ± 7.57) were found to be statistically different between the groups. All domains except the physical domain were significantly different between the groups. Duration of marriage (β = -0.529), number of previous sexual partners (β = -0.410), total number of working hours per day (β = -0.345), types of infertility (β = -0.34), and history of the sexually transmitted disease (β = -0.277), in decreasing order of effect, were found to be associated with the quality of life of infertile women (R2 = 0.725).ConclusionsThe study found that infertile women had a lower mean HRQoL score compared to fertile women, with all domains except for the physical domain being significantly different between the two groups. This suggests that infertility can have a significant impact on various aspects of a woman's life, including her emotional well-being, social functioning, and psychological health. The factors associated with the quality of life of infertile women were the duration of marriage, the number of previous sexual partners, the total number of working hours per day, the types of infertility, and the history of sexually transmitted diseases, with duration of marriage having the strongest association. These findings highlight the need for healthcare providers to address the psychological and social aspects of infertility.

Rehabilitation Is Associated With Improvements in Post-COVID-19 Sequelae.

Post-COVID-19 syndrome has affected millions of people, with rehabilitation being at the center of non-pharmacologic care. However, numerous published studies show conflicting results due to, among other factors, considerable variation in subject characteristics. Currently, the effects of age, sex, time of implementation, and prior disease severity on the outcomes of a supervised rehabilitation program after COVID-19 remain unknown. This was a non-randomized case-control study. Subjects with post-COVID-19 sequelae were enrolled. Among study participants, those who could attend an 8-week, supervised rehabilitation program composed the intervention group, whereas those who couldn't the control group. Measurements were collected at baseline and 8 weeks thereafter. Study groups (N = 119) had similar baseline measurements. Participation in rehabilitation (n = 47) was associated with clinically important improvements in the 6-min walk test (6MWT) distance, adjusted (for potential confounders) odds ratio (AOR) 4.56 (95% CI 1.95-10.66); 1-min sit-to-stand test, AOR 4.64 (1.88-11.48); Short Physical Performance Battery, AOR 7.93 (2.82-22.26); health-related quality of life (HRQOL) 5-level EuroQol-5D (Visual Analog Scale), AOR 3.12 (1.37-7.08); Montreal Cognitive Assessment, AOR 6.25 (2.16-18.04); International Physical Activity Questionnaire, AOR 3.63 (1.53-8.59); Fatigue Severity Scale, AOR 4.07 (1.51-10.98); Chalder Fatigue Scale (bimodal score), AOR 3.33 (1.45-7.67); Modified Medical Research Council dyspnea scale (mMRC), AOR 4.43 (1.83-10.74); Post-COVID-19 Functional Scale (PCFS), AOR 3.46 (1.51-7.95); and COPD Assessment Test, AOR 7.40 (2.92-18.75). Time from disease onset was marginally associated only with 6MWT distance, AOR 0.99 (0.99-1.00). Prior hospitalization was associated with clinically important improvements in the mMRC dyspnea scale, AOR 3.50 (1.06-11.51); and PCFS, AOR 3.42 (1.16-10.06). Age, sex, and ICU admission were not associated with the results of any of the aforementioned tests/grading scales. In this non-randomized, case-control study, post-COVID-19 rehabilitation was associated with improvements in physical function, activity, HRQOL, respiratory symptoms, fatigue, and cognitive impairment. These associations were observed independently of timing of rehabilitation, age, sex, prior hospitalization, and ICU admission.
