Abstract

Background
Smartwatches are increasingly used to monitor and motivate physical activity. Patients with cardiovascular disease (CVD) and peripheral artery disease (PAD) often do not meet national physical activity recommendations. They may, thus, benefit from a physical activity program using smartwatches. The Life Plus smartwatch is designed to facilitate activity monitoring by counting steps, but its validity needs to be determined, particularly in patients who may not have a normal gait, such as those with cardiovascular pathology.

Objective
This study evaluates the accuracy of the Life Plus smartwatch (versions 2 and 3) in healthy adults, patients with CVD, and patients with PAD at different walking speeds (1.8, 2.5, 3.2, and 4 km/h) and different localizations (wrists, hips, and ankles) to determine best accuracy.

Methods
In total, 34 participants, comprising healthy individuals (n=10), patients with CVD (n=14), and patients with PAD (n=10), wore 6 Life Plus watches simultaneously (3 of version 2 and 3 of version 3), located on wrists, hips, and ankles. Participants walked on a treadmill for 3-minute sessions at speeds of 1.8, 2.5, 3.2, and 4 km/h; they then performed a 10-minute free walking on the ground and again walked for 3-minute sessions on a treadmill at the same speeds. Actual step counts were recorded through video footage.

Results
When worn at the wrist, no significant difference between the actual number of steps and step count by version 2 watches was found in each group independently (healthy group: P=.25; CVD group: P=.50; and PAD group: P=.37). Significant differences were found with the version 2 watches at the wrist in the healthy group at 3.2 (−5.26%; P=.01) and 4 km/h (−6.13%; P=.008) and in the CVD group at 2.5 (−5.94%; P=.008), 3.2(−13.1%; P=.008), and 4 km/h (−13.96%; P=.004). When worn at the wrist, no significant difference between actual number of steps and step count by version 3 watches was found in the healthy group (P=.02) and the PAD group (P=.90). Significant differences were found with the version 3 watches at the wrist in the CVD group at 3.2 (−6.43%; P=.001) and 4 km/h (−7.3%; P=.01) and in the PAD group at 4 km/h (−5.77%; P=.04).

Conclusions
For optimized counting when worn at the wrist, healthy individuals should prefer version 2 watches for slow walking (1.8 and 2.5 km/h) and version 3 for higher speeds (3.2 and 4 km/h). Patients (CVD and PAD) should prefer version 2 watches at 1.8 km/h and version 3 watches for higher speeds (2.5, 3.2, and 4 km/h).
Interpreting the Influence of Using Blood Donor Residual Samples for SARS-CoV-2 Seroprevalence Studies in Japan: Cross-Sectional Survey Study

Published: February 2025

Abstract
Background: Residual blood donor samples are commonly used in SARS-CoV-2 seroepidemiological studies; however their use may introduce bias due to the healthy donor effect, wherein blood donors are generally healthier than the general population. This potential bias is critical for accurately interpreting seroepidemiological data, as blood donors might not fully represent broader population-level infection rates.
Objective: This study aims to assess the potential bias in SARS-CoV-2 seroprevalence estimates derived from blood donor samples in Japan by examining the association between blood donation history and COVID-19 diagnosis. By quantifying the healthy donor effect, we seek to refine the interpretation of SARS-CoV-2 seroepidemiological studies using residual blood donor samples.
Methods: We conducted a web-based survey from December 14 to 28, 2023, recruiting 10,781 Japanese residents aged 16‐69, stratified by demographic factors to match national representation. Participants provided information on demographics, socioeconomic status, COVID-19 vaccination history, comorbidities, and blood donation experience. A logistic regression model adjusting for confounders such as age, sex, education, occupation, comorbidities, and vaccination status, was used to estimate the odds of COVID-19 diagnosis among blood donors compared to nondonors.
Results: Of the 10,781 participants, 3583 (33.2%) reported a history of COVID-19 diagnosis, and 5015 (46.5%) indicated they had donated blood at least once in their lifetime, and 1128 (10.5%) donated within the last year. Blood donors had mean of 13.5 (SD 43.6) donations and were older, with a mean age of 46.4 (SD 13.9) years, compared to 38.5 (SD 14.1) years for nondonors. Among blood donors, 39.9% had comorbidities (95% CI 38.5‐41.2) compared to 27.9% (95% CI 26.7‐29.0) of nondonors. Blood donors had 1.62 (95% CI: 1.48‐1.78) times higher odds of COVID-19 diagnosis compared to nondonors. The higher diagnosis rate among blood donors likely reflects increased social interactions and health-seeking behaviors, a phenomenon we refer to as the inverse healthy donor effect. This suggests that blood donor samples could overestimate SARS-CoV-2 seroprevalence when generalized to the broader Japanese population.
Conclusions: Higher COVID-19 diagnosis rates among blood donors may reflect increased community involvement and health-seeking behaviors, suggesting an inverse healthy donor effect. This pattern indicates that in terms of SARS-CoV-2 infection, blood donors might not represent the healthiest segment of the population. Consequently, seroprevalence studies using blood donor samples could overestimate SARS-CoV-2 infection rates in the general Japanese population. For more accurate public health surveillance, the development of statistical methods to adjust for this bias is recommended.

Wachstumsschwäche überwinden: Nicht mehr Schulden, sondern mehr Produktivitätswachstum ist der Schlüssel
Authors: Holtemöller Oliver 
Published: February 2025

Abstract
Short- and medium-term growth perspectives in Germany are bleak. This is putting the public budget under stress. A reform of the debt brake could increase public financial leeway, but would not in itself solve the fundamental economic problems. Even with a higher permissible level of government debt, pension system expenditure will rise sharply, and real shortages, for example in the labour market, cannot be resolved in the short term with more debt either. The new federal government should therefore focus more on promoting productivity. A change in policy towards more market-based solutions and fewer national unilateral actions, for example, could unlock potential in the energy transition.
Peran Filantropi Islam Wakaf dalam Kebencanaan

This study explores the opportunities and obstacles in utilizing waqf as a component of alternative funding during the disaster cycle. Indonesia faces a significant risk of natural disasters; nonetheless, funding for prevention, readiness, and rebuilding remains insufficient. Conversely, as the nation with the highest Muslim population globally, the significance of Islamic philanthropy, specifically the potential of waqf in Indonesia, is substantial, integrating waqf into disaster management if executed correctly and backed by a sufficient ecosystem, including effective regulations and supportive administration. Indonesia is a nation that frequently faces natural disasters because of its geographically susceptible position, including the equatorial line, the convergence of tectonic plates, and the Circum-Pacific and Circum-Mediterranean zones. Catastrophes result in considerable economic damage, resulting in heightened poverty levels. Waqf can serve as a pertinent funding source for disaster management since its main aim is to use waqf assets based on their purposes, allowing it to effectively act as a tool for disaster prevention and for rebuilding after disasters. Through the use of waqf resources, the government, along with waqf management organizations, can oversee waqf funds as disaster relief funds to assist in managing disasters in Indonesia. The prospect for waqf in Indonesia is shown to be substantial, as illustrated by the waqf land in 2003, which spanned 154 hectares and had an estimated value of IDR 590 trillion. As of March 2024, waqf land is distributed across 440,512 sites, comprising 72% mosques and prayer areas, 14.5% madrasas, 4.5% burial grounds, and 9% various others.

Batik is one of the works owned by the Indonesian Nation, which has noble values and is recognized by other nations. The rapid development of batik makes batik makers need to pay attention to the production process carried out, In carrying out the activities of making stamped batik, it has not been supported by a special work table. Still using an ordinary stamp table that is less comfortable to use for stamped batik. So that in doing their work craftsmen have low productivity and efficiency. This research was conducted at PT XYZ to evaluate and reduce the risk of musculoskeletal disorders in stamped batik makers through ergonomic work table redesign. The research method used is case study-based quantitative, with a population of PT XYZ employees who work as stamped batik makers. Primary data was collected through observation, questionnaires and interviews. Posture measurements were carried out using the NBM (Nordic Body Map) questionnaire, to determine musculoskeletal complaints including 28 muscle parts in the musculoskeletal system on both sides of the body right and left. Then posture measurements were taken using the REBA (Rapid Entire Body Assesment) method. The results of the NBM questionnaire showed that before the improvement of the stamp batik had a high chart of complaints of pain in the musculoskeletal muscles and also the results of the REBA score showed a high risk of musculoskeletal disorders, especially in the neck, shoulders, bronze, arms and legs. After the implementation of a more comfortable stamp work table design and stamp stove table (Adjustable) there was a significant decrease in the REBA score decreasing from 8 to 1. This shows a significant reduction in the risk of musculoskeletal disorders, so that ergonomic work table design can reduce the risk of musculoskeletal disorders at PT XYZ and increase worker comfort.

Efficacy and Safety of Different Durations of Dual Antiplatelet Therapy for Acute Coronary Syndrome in Patients with Chronic Kidney Disease: A Systematic Review
Authors: Suryohusodo Aileen Alessandra , Cahyadi Alius , Tjhin Charens , Iryaningrum Maria Riastuti 
Published: February 2025

Background
In this systematic review, we evaluated the efficacy and safety of different durations of dual antiplatelet therapy (DAPT), which consists of aspirin and a P2Y12 inhibitor, in patients with concomitant chronic kidney disease (CKD) and acute coronary syndrome (ACS).

Materials and Methods
We searched PubMed, Cochrane, and Proquest from inception to January 2024 with the terms “acute coronary syndrome,” “chronic kidney disease,” and “dual antiplatelet therapy”, and a ten-year publication date restriction. We included observational studies that assessed the impact of DAPT on major adverse cardiovascular events (MACE) and safety outcomes, specifically major and minor bleeding events. The included studies involved patients with ACS diagnoses who also had CKD. Risk of bias assessment was assessed regarding selection, comparability, and outcome.

Results
We included eight studies involving 166,290 participants—six studies with a retrospective design and two with a prospective design. The quality of evidence was generally good. Six studies showed a significantly difference incidence of MACE in prolonged DAPT administration, in which five of them showed a decreased incidence. One study reported a higher two-year mortality in patients with CKD and prolonged DAPT compared to the general population. Bleeding risks were increased significantly in prolonged DAPT in two studies, five studies reported no significant difference in bleeding incidence, and one study reported a higher rate of adverse outcomes in lower estimated glomerular filtration rate compared to healthy patients when given DAPT for > 12 months.

Conclusion
Prolonged DAPT administration may decrease the risk of MACE with no increased risk in bleeding occurrences in patients with concomitant CKD and ACS.
Esthetic and reconstructive options for earlobe deformities
Authors: Wollina Uwe , Goldman Alberto , Machado Luz Pedro , Guindani Marson Valentina 
Published: February 2025

Background:
The earlobe plays a significant role in framing the face and complementing the appearance of earrings, hairstyles, and other facial features. In addition to the growth of the earlobes with the aging process, other changes can compromise the shape, size, and overall youthful appearance of this region. The main changes are evidenced by the elongation and ptosis of the earlobes, loss, atrophy of soft tissues, and formation of wrinkles in addition to deformities produced by surgical procedures, placement of earrings, and piercings or earlobe gauging.

Objective:
The authors describe the main changes in the earlobes and review the current treatment modality for earlobe rejuvenation and reconstruction, addressing the anatomy, common esthetic concerns, and various therapeutic approaches.

Methods:
A narrative review of treatment options was performed. We searched PubMed databases. Based on the diagnosis of changes, less invasive surgical procedures, use of laser, and fillers with fat or hyaluronic acid represent therapeutic options.

Results:
Significant improvement of the senile earlobe and correction of anatomical and esthetic deformities can be attenuated or corrected through different approaches. Proper diagnosis of the changes will determine the best treatment or even the combination of procedures.

Conclusion:
Surgical procedures, laser rejuvenation, fat injection, and fillers represent simple and effective options for treating esthetic problems and acquired deformities of the earlobes.

Objectives:
This study aimed to investigate the accuracy of myocardial extracellular volume (ECV) quantification using a prototype photon-counting detector (PCD) computed tomography (CT) and examine the association between radiation dose and spectral image settings.

Material and Methods:
A multi-energy CT phantom that simulated the blood pool and myocardium was used. The tube voltage was set at 120 kVp and three types of tube current-time products (105, 150, and 300 mAs) were applied for pre- and post-contrast scans. Virtual monoenergetic images (VMIs) at 50–100 keV were reconstructed. The ECV value was calculated from the CT numbers between pre-contrast and post-contrast. We compared the accuracy of ECV values at each VMI level.

Results:
Each radiation dose setting demonstrated a small but significant difference in ECV values at each keV level. ECV was overestimated at higher keV in all radiation dose settings. A significant difference in ECV value variabilities was found among keV levels in all three radiation dose settings, with higher keV exhibiting greater variability. The variation was particularly large in the low-dose setting. The residual values were significantly larger at higher keV levels in all radiation dose settings. The residual values were smaller at 50 and 60 keV with no significant difference in 150- and 300-mAs settings.

Conclusion:
Setting appropriate VMI keV and radiation dose settings was necessary when quantifying myocardial ECV with PCD-CT because the keV levels caused differences in the quantification value and measurement variation.
Management of ventral hernias: treatment results based on the developed algorithm
Authors: Ioffe O. Y. , Tarasiuk T. V. , Kryvopustov M. S. , Stetsenko O. P. 
Published: February 2025

The surgical treatment of anterior abdominal wall hernias is one of the most common procedures in elective surgery. However, the rate of laparoscopic hernioplasty is lower when compared to open methods. Experience in treating large ventral hernias (і 10 cm) using minimally invasive techniques is limited due to the inability to compare the edges of the hernial defect without component separation.
Objective — to develop an algorithm for choosing a surgical treatment method for patients with ventral hernias and to evaluate the results of treatment.
Materials and methods. A prospective multicenter study was conducted, which included 534 patients with ventral hernias of various sizes. All patients were treated from September 2011 to November 2024. Preoperatively, patients with hernias ≥10 cm were injected with 100 Units of botulinum toxin type A (BTA) into the muscles of the anterior abdominal wall. The mean age of the patients was 56.49±14.59 years, with 307 (57.5%) women and 227 (42.5%) men. All patients underwent hernia surgery using laparoscopic and open hernioplasty methods according to the developed algorithm.
Results. The algorithm classified patients into three groups based on their hernia size: group 1 — patients with hernias <4 cm wide (n=269; 50.4%), group 2 — with a size of 4—10 cm (n=173; 32.4%), and group 3 — with a size of ≥10 cm (n=92; 17.2%). The mesh was placed intraperitoneally during laparoscopic hernia repair. In all three groups, laparoscopic hernioplasty demonstrated a significantly lower rate of complications and length of hospital stay compared to open procedures (p <0.01). Seromas were among the most common complications in all three groups in our study (n=19; 7.1% vs n=26; 15.0% vs n=14; 50%), and their frequency increased with hernia defect size. In group 3, among patients with large hernias, BTA administration allowed for the reduction of the aponeurosis defect to ≤10 cm in size in 89.4% of cases and the performance of laparoscopic surgery in patients who agreed to it. The recurrence rate after laparoscopic surgery was 0.8%, while after open surgery, it was 1.1%.
Conclusions. The use of the algorithm for selecting the hernioplasty method allows implementing a personalized approach to the surgical treatment of patients with ventral hernias. Laparoscopic hernioplasty with intraperitoneal mesh placement demonstrates significantly better results compared to open methods of hernia repair in terms of length of hospital stay and complication rate (p <0.01). The use of BTA for hernias ≥10 cm in the preoperative period makes it possible to perform hernioplasty using laparoscopic techniques and minimize surgical trauma in case the patient refuses laparoscopy.
