COMPLEX PHYSICAL THERAPY OF PATIENTS WITH ADHESIVE CAPSULITIS

Adhesive capsulitis is predominantly an idiopathic condition and is more common in patients with metabolic disorders. PS contracture can be of varying degrees of severity, depending on the pathology of the PS with which we are dealing. This condition greatly aff ects work capacity and quality of life due to the presence of pain, discomfort and limitation of daily life activities. Prolonged pain syndrome can provoke sleep disorders and depression. Disruption of normal sleep, pain and depression form a pathological closed circle and contribute to the maintenance of the pathological process in the locus morbi.The development of a comprehensive program of physical therapy for patients with adhesive capsulitis with the use of modern means of recovery, which will reduce the risk of the disease re-emerging, and will also contribute to the faster recovery of the functional capacity of the musculoskeletal system of the patients.The objective of the study. The develop and practically substantiate a comprehensive program of therapy for patients with adhesive capsulitis using physical therapy.Materials and Research Methods. The study is based on a comprehensive therapeutic approach for 36 patients diagnosed with adhesive capsulitis in the acute phase of the condition. The assessed parameters included X-ray and computed tomography results, evaluation of range of motion in the shoulder joint, joint- muscle apparatus, and analysis of pain intensity indicators.Conclusions. To improve the condition of patients and optimize the process of treatment and rehabilitation of patients with adhesive capsulitis of the shoulder joint in the acute period, it is advisable to use with the diff erentiation of means of therapeutic intervention according to the diagnosis of the international classifi cation of functioning, optimization of physiotherapeutic means and special means of physical therapy allowed to shorten the terms of treatment and recovery of patients with adhesive capsulitis. It was determined that the best combination of means of therapeutic intervention for patients with adhesive capsulitis is the use of a complex of ideomotor exercises to create the patient’s idea of correct movement; correct positioning of the limb during sleep, everyday and professional activity; passive exercises to increase the volume of painless movements (bending, external rotation); restorationof the pattern of typical motor actions and optimization of physiotherapeutic means due to the use of shock wave and TENS therapy signifi cantly improved the eff ectiveness of their recovery in the short-term and long-term stages of the acute period of rehabilitation.

Comprehensive treatment of the patient with venous trophic ulcer

Improving the results of treatment for patients with varicose veins in the lower extremities, complicated by trophic ulcers, is an urgent task for modern medicine. A long-term, recurrent course of the disease leads to a reduction in working capacity and deterioration in quality of life, as well as permanent disability for patients, whose treatment causes special economic problems. At present, there are virtually no effective methods for conservative therapy, leading to prolonged unsuccessful treatment of such patients. This article presents the clinical case of a 63-year-old patient undergoing complex treatment for chronic lower limb venous insufficiency of class C6 according to the CEAP classification. Conclusion. An effective complex method for treating trophic ulcers in patients with chronic venous disease involves the correction of venous hemodynamic disorders (in this case, through radiofrequency ablation), as well as primary surgical treatment for the ulcerative defect, and simultaneous autodermaplasty with a perforated skin flap.

Quality of life as a reflection of metabolic indicators in patients undergoing programmed hemodialysis

Metabolic disorders associated with chronic kidney disease (CKD) can lead to a decrease in the quality of life of patients on hemodialysis. The aim of this study is to analyze the correlation between quality of life (QOL) in patients receiving treatment with PHD and clinical and laboratory indicators. Material and methods. 251 patients with stage 5 CKD were included in the study. There were 108 men and 143 women. The mean age was 54.4 ± 9.9 years. All participants completed a specific quality of life questionnaire KDQOL-SF. Results. The interviewed patients reported more concern about symptoms such as weakness, dizziness, and muscle pain (U = 765, p < 0.001), which was correlated with albumin levels (R = 0.5, p < 0.01) and calcium-phosphorus product levels (R = –0.48, p < 0.05). They also expressed concern about the inability to travel or follow a special diet (U = 553, p < 0.005), which correlated with heart rate levels (R = –0.51, P < 0.1) and serum potassium levels (R = –0.6, P < 0.1). Additionally, the burden of CKD correlated with triglycerides (R = 0.36, p = 0,01).Work capacity is associated with age (R = –0.54; p < 0.001), eKT/V (R = 0.47; p < 0.01). Indicators of cognitive function correlate with blood pressure (BP) (R = –0.51, p < 0,001) and pulse pressure (P = –0,55, p < 0,01). Sexual functions are associated with BP (R = –0,64, p < 0,05), calcium levels (R = 0,76, p > 0.80), iron (0,42, p = 0,90), transferrin saturation coefficient (0.5, p = 0.91). Sleep quality correlates with calcium-phosphate production (0.3, p > 0.15). The feeling of social support correlates with magnesium (0,3, P > 0,8), calcium (0.2, P > 0,1). Conclusions. Correlations between quality of life, blood pressure, albumin, and calcium phosphate metabolism, iron, were found.

Ultrahigh-surface area covalent organic frameworks for methane adsorption.

Developing porous materials with ultrahigh surface areas for gas storage (for example, methane) is attractive but challenging. Here, we report two isostructural three-dimensional covalent organic frameworks (COFs) with a rare self-catenated alb-3,6-Ccc2 topology and a pore size of 1.1 nanometer. Notably, these imine-linked microporous COFs show both high gravimetric Brunauer-Emmett-Teller (BET) surface areas (~4400 square meters per gram) and volumetric BET surface areas (~1900 square meters per cubic centimeter). Moreover, their volumetric methane uptake reaches up to 264 cubic centimeter (standard temperature and pressure) per cubic centimeter [cm3 (STP) cm-3] at 100 bar and 298 kelvin, and they exhibit the highest volumetric working capacity of 237 cm3 (STP) cm-3 at 5 to 100 bar and 298 kelvin among all reported porous crystalline materials.

The article is devoted to the study of the formation of professionally important qualities (hereinafter referred to as PIC) of students at the Barnaul Law Institute of the Ministry of Internal Affairs of Russia, ensuring their moral and psychological stability (honesty, discipline, responsibility, justice, etc.). An analysis of expert assessments of the formation of professionally important qualities grouped into four clusters "Moral stability", "Sustainability of working capacity", "Self-organization in professional activity", "Extroversion, social activity" was conducted on a representative sample (over 600 respondents). A comparative analysis by forms of study (full-time, part-time, faculty of professional retraining - short-term full-time programs) showed that students of the correspondence form of study included in practical professional activity, assess the formation of "professionally important qualities of students" significantly higher than students of other forms, with the exception of the cluster "Self-organization in professional activity". A comparative analysis of expert assessments of full-time students of the 2nd and 4th years demonstrated positive dynamics in three clusters, proving the overall effectiveness of the educational work of the university. Stagnation of indicators is observed for the factor "sustainability of working capacity". The results of the study formed the basis for developing the content of the course "Professional Ethics and Service Etiquette". The experience of implementing the project method as a technology for developing "professionally important qualities of students" is substantiated and described

Outcomes of laser hemorrhoidoplasty for grade II-IV hemorrhoidal disease in Bangladesh.

Laser hemorrhoidoplasty is a minimally invasive procedure to treat hemorrhoids and has shown better outcomes. Less is known about its utility in a lower middle-income country; Bangladesh. Between March 2023 and December 2023, 86 patients with grade II-IV hemorrhoids underwent laser hemorroidoplasty. Follow up was assessed on 1st week, 2nd week, and 6th week including pain, satisfaction, symptom improvement, incapacity for work, complications, reduction, and recurrence. The study included 86 patients, with a higher proportion of male participants (73.3%) and a mean age of 55.43±13.6 years. The majority of subjects (68.60%) had grade 3 hemorrhoids. The average surgery duration was 14.70±4.70minutes All individuals experienced substantial decreases in the size of their hemorrhoids (100%) and reported high levels of satisfaction after the operation (97.7%). The use of the Wilcoxon signed-rank test demonstrated a statistically significant reduction in both the Visual Analog Scale (VAS) and Patient Global Impression of Improvement (PGI-I) ratings during the three subsequent observation periods (1st week, 2nd week, and 6th week). The 6th week complication rate was 19.8%. Additional mucopexy was performed on all patients with grade IV and three patients with grade III hemorrhoids. Laser hemorroidoplasty is a day-care procedure, that is safe and efficacious and can be used in rural area settings with good patient satisfaction. Mucopexy is required in some cases of large hemorrhoidal mass to prevent recurrence.

Reintegration into the workforce after kidney transplantation based on urbanization status in Switzerland

IntroductionSwitzerland's urban areas concentrate most of its population and employment opportunities. While kidney transplantation (KT) is the preferred therapy for eligible candidates, individuals in rural areas face challenges accessing specialized medical services due to longer travel distances. Limited understanding exists regarding patients' perspectives on returning to work after KT and whether this correlates with their urbanization status, potentially influencing outcomes. MethodsRetrospective, nationwide (Swiss Transplant Cohort Study) study, from May 2008 to 2020, including 1926 patients aged 18-60 years who underwent KT. We investigated the self-reported work reintegration at 1-, 3- and 5-years after the KT, the recipient and allograft survival and the allograft function at 12 months, contingent on urbanization status (urban, suburban, rural). ResultsThe return rate of sufficiently filled-in questionnaires was 81% (1053 participants). Urban recipients were younger, had longer dialysis time before KT, less living donor KT (LDT). At baseline, the level of education was lower, as well as the workforce, defined as work capacity > 50% (37% urban, 39% suburban, 47% rural). Regression analysis revealed significantly higher Odds Ratio (OR) for employment 1-year post-KT among patients residing in rural and suburban areas (OR 1.31 [CI: 1.04-1.65] and 1.52 [CI: 1.16-1.98], respectively) compared to patients from urban regions. Stratified according to urbanization environment, recipient and allograft survival were comparable across groups. ConclusionsPatient and graft outcomes were favorable, with improved work reintegration observed at the 1-year mark post-KT for recipients from rural backgrounds compared to those from suburban and urban areas.

Dual-bonded polyethyleneimine network with electron-withdrawing groups at α, β-sites for ultra-stable and low-energy CO2 capture in harsh environments

As an innovative approach to addressing climate change, significant efforts have been dedicated to the development of amine sorbents for CO2 capture. However, the high energy requirements and limited lifespan of these sorbents, such as oxidative and water stability, pose significant challenges to their widespread commercial adoption. Moreover, the understanding of the relationship between adsorption energy and adsorption sites is not known. In this work, a dual-bond strategy was used to create novel secondary amine structures by a polyethyleneimine (PEI) network with electron-extracted (EE) amine sites at adjacent sites, thereby weakening the CO2 binding energy while maintaining the binding ability. In-situ FT-IR and DFT demonstrated the oxygen-containing functional groups adjacent to the amino group withdraw electrons from the N atom, thereby reducing the CO2 adsorption capacity of the secondary amine, resulting in lower regeneration energy consumption of 1.39 GJ t−1-CO2. In addition, the EE sorbents demonstrated remarkable performance with retention of over 90 % of their working capacity after 100 cycles, even under harsh conditions containing 10 % O2 and 20 % H2O. DFT calculations were employed to clarify for the first time the mechanism that the oxygen functional group at the α-site hinders the formation of the urea structure, thereby being an antioxidant. These findings highlight the promising potential of such sorbents for deployment in various CO2 emission scenarios, irrespective of environmental conditions.

Independent and joint relationships of cardiorespiratory fitness and body mass index with liver fat content.

To investigate the relationship between cardiorespiratory fitness (CRF) and liver fat content (LFC) in community-based participants and highlight their relationship in people with different body mass indices (BMIs). Using UK Biobank data, CRF was estimated with bicycle ergometer fitness testing and was evaluated based on physical work capacity at 75% maximum heart rate (PWC75%). LFC was quantified through liver proton density fat fraction (PDFF) on magnetic resonance imaging. Multivariate linear regression models were used to analyse the associations of CRF and BMI with absolute reduction and percentage change in PDFF (%). In total, 5765 participants with a mean age of 55.57 years and a median (range) follow-up of 10.7 (4.0-17.7) years were included. Compared with the lowest PWC75% tertile, the absolute reduction and percentage change in PDFF in the highest PWC75% tertile were -0.450 (95% confidence interval [CI] -0.699 to -0.192) and -4.152 (95% CI -6.044 to -2.104), respectively. These associations were independent of BMI, and individuals with obesity and normal weight had the largest absolute reduction and percentage change in LFC, respectively (p for interaction <0.001). Joint analysis showed that PWC75% and BMI had a negative dose-response relationship with PDFF. These associations were consistent in different sex and age subgroups (p for interaction >0.05). There was a significant negative association between CRF and LFC, and this association was independent of BMI. The results of this study strongly recommend improving CRF to mitigate LFC.

Massage prior to exercise delays the onset of the physical working capacity at the fatigue threshold (PWCFT).

Functional massage (FM) is a soft tissue technique that incorporates non-end range joint movement with tissue compression to treat musculotendinous pain and dysfunction. FM has been associated with promoting neural excitability and neuromuscular efficiency. In clinical practice, FM may be used at the beginning of a treatment session to prepare fibers of the target muscle and surrounding soft tissues for functional activity. The Physical Working Capacity at the Fatigue Threshold (PWC<inf>FT</inf>) uses surface electromyography (EMG) to demarcate between non-fatiguing and fatiguing exercise. To our knowledge, no studies have examined the efficacy of FM when performed prior to an exercise session. The purpose of this study was to determine whether pre-performance FM delays the onset of neuromuscular fatigue. We hypothesized that FM would increase maximal power output as well as PWC<inf>FT</inf> compared to the control condition. Thirteen healthy college-aged men (mean±SEM: age, 24.1±0.5 years; weight, 83.0±3.2 kg; and height, 1.80±0.02 m) ranging from 22 to 28 years-old volunteered for the present study. On two occasions separated by at least 7 days, participants visited the laboratory to perform single-leg knee-extensor ergometer exercise after either receiving 7 min of FM (experimental condition) or no FM (control condition). The results indicated that the onset of neuromuscular fatigue was significantly delayed for the absolute and relative PWC<inf>FT</inf> (~80%) values compared to the control condition. There was no significant mean difference between FM and control for maximal power output. The findings of the present study indicated that FM was effective in delaying neuromuscular fatigue as assessed by PWC<inf>FT</inf>. These findings may be applicable to both athletic and clinical settings as FM prior to exercise may help to prime a target muscle before training.

Validity and feasibility of four standardized aerobic fitness tests in patients with depression: A cross-sectional study

The objective of this study was to examine the validity and feasibility of four standardized aerobic fitness tests to either measure O2peak or to estimate O2max (e O2max) in patients with major depression disorder (MDD). To this end, all subjects (n=43) performed one maximal cardiopulmonary exercise test with gas exchange measurement (CPET) on a bicycle ergometer. Additionally, three submaximal tests (Åstrand-Rhyming bicycle ergometer test [ART], Physical work capacity test [PWC], and 6-min walk test [6MWT]) were performed within two weeks in counterbalanced order. e O2max from the submaximal tests was compared to the measured O2peak from CPET using rANOVAs, Bland-Altman plots, and correlation analyses. Feasibility outcomes (e.g., perceived exertion, discomfort, pretest anxiety, etc.) were compared via rANOVAs. On group level, e O2max estimated submaximally via ART and PWC did not differ from the CPET-based O2peak, whereas there was a bias in the 6MWT, as differences of the means increased in participants with higher O2peak. During CPET, only 56% achieved a primary or secondary criterion of maximum (physiological) exertion. On the group level, O2peak and e O2max determined with the different tests showed a sufficient degree of agreement (r≥.54, ICCs≥0.66, p<.001), but on the individual level, marked differences occurred between CPET-based O2peak and e O2max. Three of four CRF tests (CPET, ART, PWC) proved to be feasible and could be integrated into everyday therapy and monitoring of patients with MDD as an estimate for improvement of aerobic fitness. For the exact measurement of O2peak, CPET remains the gold standard, also in patients with MDD.

A new control strategy of direct exergy balance for coal-fired power plants: Fundamentals and performance evaluation

In order to facilitate the increasing penetration of grid-connected renewable power, coal-fired power plants should operate more and more flexibly. Most of the-state-of-the-art control strategies, which are mainly based on the idea of direct energy balance, cannot perform well when coal-fired power plants change load with high load cycling ramp rate. To enhance the operational flexibility of coal-fired power plants, the control idea of the direct exergy balance is proposed in this study, which directly characterizes the work capacity balance between the boiler and the steam turbine. The new control strategy of direct exergy balance emphasizes the feedback of the deviation between the turbine exergy demand signal and the boiler exergy signal. Dynamic models of a reference power plant were developed and validated, and performances of control strategies based on direct energy balance and direct exergy balance were evaluated and compared. In the 50 %–75 % load cycling process of the reference power plant, the control strategy of direct exergy balance demonstrated markedly improvements in the load cycling ramp rate (29 % relatively), the load cycling comprehensive index Kp (39.4 %), and reduction in the maximum deviations (28.2 %), overshoots (59.8 %), and cumulative deviations (36.9 %) of the key thermal parameters. In conclusion, the control strategy of direct exergy balance significantly strengthens the control performance during rapid load cycling processes and attains a notable enhancement in operational flexibility and a slight improvement in energy efficiency of coal-fired power plant.

Triggerpunkt-Behandlungs-Tool zur Selbsttherapie von Myogelosen im Berufsumfeld – eine Anwendungsbeobachtung

Trigger point treatment tool for self-therapy of myogelosis in the professional environment – An observational study Aim: There is a large number of occupations where workplace-associated movement patterns and/or forced postures lead to muscle tension in the shoulders and back. These tensions have a direct detrimental impact on the quality of life and capacity for work of those affected. In the medium to long term, they also promote the development of structural degeneration of the musculoskeletal system. If employees in the healthcare sector are affected, this impairs high-quality patient care. The trigger point self-treatment tool “TensionTerminator” (ErgoPhysion, Innsbruck, Austria) was developed for the self-therapy of such tension conditions in the workplace. The use of this device was evaluated as part of an application observation in six departments at Vienna General Hospital (AKH). Methods: Six departments at Vienna General Hospital from the areas of surgery, laboratory medicine, internal medicine and radiology were each provided with a “TensionTerminator” device for independent use for 4 months between May 2023 and March 2024. A contact person in each department was trained in the use of the device and how to handle the documentation. As part of the observation, users were asked to independently enter their user ID, the duration of use and their subjective assessment of the effect (“better”/”worse”/”no change”) in a list each time they used the device. Results: During the test period, a total of 430 uses by 145 users were documented in the six departments, i.e. an average of almost 3 uses per person. The average application duration was 6.5 minutes. In 85.1% of all uses, the patient’s condition after use was described as “better”, and in 14% of all cases as “no change”. One of the 430 uses received a negative rating (“worse”). Conclusion: The trigger point self-treatment tool “TensionTerminator” has proven to be an effective device against workplace-associated muscle tension. It was received very well in the hospital setting and was used regularly. Keywords: workplace health promotion – back pain – myogelosis – myofascial trigger points

Flyrock in surface mining-Part 3: Shock wave, stress wave, blasthole expansion

The generally accepted view in rock blasting is that the sources of energy for the fracture and movement of rock reside in the shock wave and gas action resulting from the explosion, and yet the mechanisms by which these sources interact with the rock have remained unclarified. It has also been noted that up to 50% of the work capacity of an explosive released in a blast cannot be accounted for by field measurements of energy partitioning. In this study, we describe a physical model that details the response of rock to both shock wave and gas action. An analytical model based on momentum conservation is derived to describe the dynamics of shock-driven expansion of the blasthole. Radial expansion of the hole is the key parameter that permits the derivation of the following characteristics of rock response to shock loads: hole expansion time; volume of displaced rock; energy consumed per unit volume; expansion energy efficiency; stress wave pulse length; gas pressure in enlarged hole. Soon after the completion of hole expansion, the shock wave degenerates to an elastic stress wave that runs through the burden. Blasthole expansions of between 50% and 300% of diameter are completed in under 1 ms and, depending on rock properties, consume 32% to 42% of the detonation energy or about 55% of the available mechanical (Gurney) energy. Gas pressure in the enlarged holes in five rock types is between 35 MPa and 650 MPa, and drives the mass movement of burden rock.

Construction of Highly Porous and Robust Hydrogen-Bonded Organic Framework for High-Capacity Clean Energy Gas Storage.

Development of highly porous and robust hydrogen-bonded organic frameworks (HOFs) for high-pressure methane and hydrogen storage remains a grand challenge due to the fragile nature of hydrogen bonds. Herein, we report a strategy of constructing the double-walled framework to target highly porous and robust HOF (ZJU-HOF-5a) for extraordinary CH4 and H2 storage. ZJU-HOF-5a features a minimized twofold interpenetration with double-walled structure, in which multiple supramolecular interactions are existed between the interpenetrated walls. This structural configuration can notably enhance the framework robustness while maintaining its high porosity, affording one of the highest gravimetric and volumetric surface areas of 3102 m2 g-1 and 1976 m2 cm-3 among the reported HOFs so far. ZJU-HOF-5a thus exhibits an extremely high volumetric H2 uptake of 43.6 g L-1 at 77 K/100 bar and working capacity of 41.3 g L-1 under combined swing conditions (77 K/100 bar→160 K/5 bar), and also impressive methane storage performance with a 5-100 bar working capacity of 187 (or 159) cm3 (STP) cm-3 at 270 K (or 296 K), outperforming most of the reported porous organic materials. Single-crystal X-ray diffraction studies on CH4-loaded ZJU-HOF-5a reveal that abundant supramolecular binding sites combined with ultrahigh porosities account for its high CH4 storage capacities. Combined with high stability, super-hydrophobicity, and easy recovery, ZJU-HOF-5a is placed among the most promising materials for H2 and CH4 storage applications.

Statistics on disability pensioners is important for assessing injury burden

Abstract Introduction We have little information about long term effects of injuries resulting in disability. In addition to human suffering and reduced quality of life, these consequences of injuries inflict a heavy burden on the national economy. All persons in Norway aged 16 - 66 years are entitled to disability pension benefits from the National Insurance Administration (NIA) if their working capacity is permanently reduced by at least 50 % due to disease, injury or defect. The burden of injuries in terms of “New disability pensioners” (NDP) related to traffic injuries was assessed in a study for the years 1992-97 and in a follow up study for 2005-12. Methods Each year, a number of persons will be registered as NDP in the Disability register of NIA. Between 1992 and 2012 accident types were classified by an additional code, one of them denoting traffic injury. To calculate rates, the number of NDP are related to the number of persons in Norway on the 1st of January minus the number of persons holding a disability pension at that time (risk population) and are shown as NDP pr 100 000 of the risk population. Results The rates for NDP due to traffic injuries increased from 16.8 in 1992 to 23.0 in 1997, an average annual increase of 7.4 %. These rates were compared with the mortality rates in the age group 15-64 years due to traffic injuries from 1988-1993. The average time lag between an injury and getting a disability pension is 4 years. These rates were 9.3 in 1988 and 6.4 in 1993, an average annual decrease of 6.2 %. The follow up study for 2005-2017 confirmed more or less this increasing trend in NDP due to traffic injuries. Conclusions The rate of NDP due to traffic injuries is increasing while mortality rates for same age group is decreasing. This might reflect that our emergency medicine now saves more and more lives, however many of them ending up as disabled. We need to get valid statistics on disability enabling us to describe the burden of traffic injuries.

6.X.1. Disentangling Long-COVID: prevalence, risk factors and impact

Abstract Background Prolonged symptoms after the acute SARS-COV2 infection significantly alter daily functioning and work ability for substantial number of people. Application of different long COVID definitions result in variable prevalence estimations, while aetiology of long COVID as well as its impact is insufficiently understood. Our workshop is set to discuss the public health impact of long COVID in the general population, to identify risk factors of developing long COVID, and stimulate dialog to advance adequate health care and public health actions aimed to reduce the impact of this condition. Objectives and Key Questions The overall objective is to discuss the public health impact as well as geographic variations across Europe in long COVID prevalence, major risk factors for long COVID and impact on work capacity, accounting for different population-based and hospital study settings. Specifically, the workshop will address the following key questions: 1) what are the challenges in estimating prevalence of long COVID? 2) what are the risk factors of long COVID and some of the most vulnerable population groups? 3) what is a distribution of long COVID in Europe? 4) what is the impact of long COVID on work ability? Brief Overview The workshop will include 3 presentations (in combined total duration of 12 min) on challenges for research and practice attributable to variability in defining long COVID, prevalence of long COVID across several European countries, risks factors of long COVID and impact on work ability. Active discussion of 13 min will conclude the session. Key messages • Standardized definitions, such as WHO-PCC definition with severity thresholds would facilitate surveillance of long COVID and advance knowledge on the risk factors related to this condition. • Understanding better the risk factors and impact of long COVID will inform more adequate screening and therapeutic strategies, and possibly anticipate effects of potential new infectious threats.

Workplace health promotion in the German Federal Armed Forces-Economic analysis and health benefits

Abstract Background In the German Federal Armed Forces (GFAF) workplace health promotion measures (WHPM) are implemented since 2015 to promote the health of military and civilian employees and thus improve the ability to defend state interests. Here the aim is to evaluate the social and health benefits associated with WHPM in relation to expenditures for WHPM. Methods Calculations are based on data from departmental reporting (full survey) on WHPM, the number of participants and days of incapacity for work (DIW). Mean indirect costs for the WHPM participation and DIW were calculated as 249.33 Euro per DIW. To assess the costs for the use of health care services and social and health benefits a longitudinal observational study (T0: 06-09/2022; T1: 06-09/2023) was conducted online and paper based. The survey invitation was addressed to 223.967 employees of the GFAF. Statistical analyses were performed using R software. Results In departments offering WHPM the chance of DIW is lower (-19%) compared to departments without WHPM offers and in case of DIW, the duration is shorter (-10%). In T0 23.568 (10.5%) and in T1 14.059 (6%) employees participated. 63.9% (T1: 3.070/4.805) reported positive effects of WHPM on their working ability and general health status (T1: 63.0% (3.013/4.782)). Of those participating in WHPM 81% (T0: 5.442/6.716) would recommend the GFAF as an employer. A number of 4.540 employees participated in both surveys, of which 2.249 participated in WHPM. The average costs per employee participating in WHPM compared to employees not participating are 0,4% higher (T0; T1: 3,5%) and thus almost equal. Conclusions Although WHPM need expenditures, the total costs per employee participating and not participating in WHPM are comparable. WHPM participants report better self-rated health status, higher working ability and commitment to the employer than non-participants. The chance of DIW is reduced in departments offering WHPM to its employees. *shared authorship Key messages • Although WHPM need expenditures, the total costs per employee participating and not participating in WHPM are comparable. • Employees participating in workplace health promotion measures report higher working ability and commitment to the employer.

Having paid work 1 year after disability claim in different types of mental and behavioural disorders

Abstract Background The majority of claimants diagnosed with a mental and/or behavioral disorder have residual work capacity, however, the chance of actual (return to) work after a disability claim assessment may differ within this diagnosis group depending on the specific type of disease. The aim of this study is to examine the associations of different mental and behavioural diseases with having paid employment one year after the claim assessment. Methods This longitudinal register based cohort study included all work disability applicants with mental and behavioural disorders assessed with residual work capacity in the Netherlands in 2016. Data were derived from the Dutch Social Security Institute (UWV) and were linked to register data on paid employment. ICD codes were used to categorize 11 disease groups (mental retardation, autism spectrum disorders, ADHD, somatoform disorders, adjustment disorders, PTSS, anxiety, personality disorders, mood affective disorders, addictions and delusional disorders. Multivariable logistic regression analyses were conducted separately for applicants who work and not work at time of the claim assessment. Results A total of 8544 claimants (mean age 45, 56% female; n = 1915 work at baseline) were included. In the working group being diagnosed with ADHD (OR 3.05, CI 1.08-8.61) or PTSS (OR 1.45, CI 1.04-2.02) was associated with paid work, and adjustment disorder was negatively associated (OR 0.74, CI 0.56-0.97). In the not-working group, autism spectrum disorder (OR 1.51, CI 1.02-2.22), personality disorder (OR 1.36, CI 1.02-1.81) and addiction (OR 1.94, CI 1.32-2.86) was associated with return to work, and somatoform (OR 0.51, CI 0.31-0.84) disorders and mood affective disorders (OR 0.83, CI 0.70-0.99) were negatively associated. Conclusions The findings of this study show different associations between type of mental and behavioural disease groups and paid employment one year after the claim assessment. Key messages • The association of either remaining at work or return to work is different among mental and behavioural diagnosis groups, therefore a different approach is indicated. • Active interventions to facilitate return to or remain at work might be indicated in specific diagnosis groups.
