RESUMEN
OBJECTIVE: Tendinopathies are diseases that often entail long-term treatment consisting of analgesics, physiotherapy, orthotics, and sparing. The aim of this study was to investigate the effect of a single application of a high-energy PEMF (pulsed electromagnetic field) on pain perception and blood born inflammation parameters. METHODS: 34 patients were randomly assigned to a verum group (10â¯min PEMF, 0,78â¯T) or a placebo group (10â¯min sham condition). Prior to and up to one week after the patient blinded treatment (t1-t5), local pain state was assessed by means of algometry as pain pressure threshold (PPT). Accordingly, heat-shock protein 70 (HSP70) levels were analysed. Statistical analyses included 2way ANOVA (2â¯× 5). The clinical trial was registered (DRKS00031321). RESULTS: After randomization and drop-out (verum nâ¯= 17, placebo nâ¯= 13) baseline-analyses did not reveal significant between-group differences for PPT (pâ¯= 0,096), for HSP70 (pâ¯= 0,524), or any other sample characteristics (pâ¯> 0,05). Pain reduction during one week of observation showed to be significantly higher (pâ¯= 0,045, η2â¯= 0,013) for the PEMF group (PPT: +83 bis +139%) compared to the placebo group (PPT:â¯+10 bis +36%). There were no HSP70 associated effects. CONCLUSIONS: A single bout of high energy PEMF led to an immediate pain relief in tendinopathy patients lasting at least for one week, but the hypothesized underlying HSP70 associated inflammatory pathway could not be confirmed.
RESUMEN
BACKGROUND: Obesity rates are rising in the armed forces of Western democratic countries, impacting military readiness and health. This highlights the need for preventive health risk assessments and countermeasures. METHODS: Using mandatory health examination data from 2018 to 2022, we analyzed the prevalence of obesity, health risks, and associated specific military risk factors (rank and unit) in 43,214 soldiers of the German Armed Forces. Statistical methods included χ2 contingencies and binary logistic regressions. RESULTS: The prevalence of obesity (BMI ≥ 30) was 18.0%. Male soldiers (OR = 3.776) and those with an officer's rank (OR = 1.244) had an increased chance for obesity. Serving in a combat unit reduced the chance of being obese (OR = .886). Considering BMI and waist circumference, 2.4% of the total sample faced extremely high cardiovascular and metabolic health risks, while 11.0% and 11.6% had very high or high health risks, respectively. CONCLUSIONS: Our data underscore the importance of targeting obesity-related health risk factors in soldiers to ensure their well-being and deployment readiness.
RESUMEN
BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic is driven by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, which has led to an enormous burden on patient morbidity and mortality. The renin-angiotensin-aldosterone system (RAAS) plays a significant role in various pulmonary diseases. Since SARS-CoV-2 utilizes the angiotensin-converting enzyme (ACE)2 receptor to exert its virulence and pathogenicity, the RAAS is of particular importance in COVID 19. METHODS: Our preliminary study investigates retrospectively the influence of selected ACE-polymorphisms (I/D location at intron 16 in the B-coding sequence (rs4646994) and A-240T (rs 4291) at the A-promoter) as well as ACE1 and ACE2 serum levels on disease severity and the inflammatory response in inpatients and outpatients with COVID-19. RESULTS: Our study included 96 outpatients and 88 inpatients (65.9% male, mean age 60 years) with COVID-19 from April to December 2020 in four locations in Germany. Of the hospitalized patients, 88.6% participants were moderately ill (n = 78, 64% male, median age 60 years), and 11.4% participants were severely ill or deceased (n = 10, 90% male, median age 71 years). We found no polymorphism-related difference in disease, in age distribution, time to hospitalization and time of hospitalization for the inpatient group. ACE1 serum levels were significantly increased in the DD compared to the II polymorphism and in the TT compared to the AA polymorphism. There was no significant difference in ACE 1 serum levels l between moderately ill and severely ill patients. However, participants requiring oxygen supplementation had significantly elevated ACE1 levels compared to participants not requiring oxygen, with no difference in ACE2 levels whereas females had significantly higher ACE2 levels. CONCLUSIONS: Although there were no differences in the distribution of ACE polymorphisms in disease severity, we found increased proinflammatory regulation of the RAAS in patients with oxygen demand and increased serum ACE2 levels in women, indicating a possible enhanced anti-inflammatory immune response. CLINICAL TRIAL REGISTRATION: PreBiSeCov: German Clinical Trials Register, DRKS-ID: DRKS00021591, Registered on 27th April 2020.

Background: COVID-19 can show a variable course, from asymptomatic infections to acute respiratory failure and death. For efficient allocation of resources, patients should be stratified according to their risk for a severe course as early as possible. Methods: 135 hospitalized patients with COVID-19 pneumonia at four German hospitals were prospectively included in this observational study. A standardized clinical laboratory profile was taken at hospital admission and a panel of serum markers with possible roles in the COVID-associated cytokine storm were also determined. 112 patients could be evaluated. The primary endpoint of ventilator requirement or death within 30 days of symptom onset was met by 13 patients. Results: Serum elevations of interleukin-6 (IL-6), procalcitonin (PCT), and C-reactive protein (CRP) at hospital admission were each highly significantly (p < 0.001) associated with ventilator requirement/death within 30 days of symptom onset. With a sensitivity of 92% and a specificity of 65-67%, IL-6 ≥ 52.8 pg/ml, PCT ≥ 0.11 ng/ml, and CRP ≥ 71.1 mg/L were predictive of a severe course of COVID-19. Positive likelihood ratios were between 2.6-2.8 and negative likelihood ratios were between 0.11-0.13 for these three markers. Conclusion: Negative likelihood ratios indicate that IL-6, PCT, and CRP at hospital admission can be used for identifying patients at low risk for severe COVID-19 progression.
RESUMEN
BACKGROUND: For seafarers on the high seas health hazards are various and due to the setting also specific. The spectrum of job-related health impairments and accidents is mainly influenced by the maritime characteristics. The aim of this study is to assess the kind of accidents and the frequency of diseases and health complaints among seafarers on German container ships by evaluating medical log books. METHODS: A systematic analysis of 14,628 medical entries from 95 medical log books of 58 container ships under German flag from 1995 to 2015 was performed. This monocentric retrospective and descriptive study used information on accidents, diseases and health complaints among different occupational groups and medical treatment procedures for the analysis and evaluation. RESULTS: The analysis showed that more than one third of all consultations with the Health Officer on board are related to internal (33.7%) and surgical (31.3%) symptoms. Almost twenty percent of consultations were due to respiratory infections (19.6%) and accidents (17.9%). Accidents represented the most frequent reason for unfitness for sea service (31.2%). Based on occupational categories, most injuries occurred among deck crew (22.5%), followed by ratings working in the engine room (18.9%). In 106 cases, telemedical contact with a physician ashore was necessary. In total, 15 seafarers had to be evacuated from the ship for further medical treatment onshore. Medicine/drug application was the most common therapeutic measure on board, accounting for 77% of all consultations. CONCLUSIONS: The high proportion of health complaints and accidents among seafarers shows that there is a need to optimize medical care at sea and accident prevention, e.g. by standardized treatment algorithms or improving the medical training of Health Officers. The development and introduction of a digital patient file to record medical treatments on the vessels could also improve medical documentation on board.

The aim of this study was to assess body mass index (BMI) and the prevalence of overweight and obesity at entry and release of service at the German Armed Forces and related associations to service duration. In a cohort study, 85,076 paired BMI data sets (entry and release of service) of German soldiers (5.4% females) between 2010 to 2022 were analyzed retrospectively to assess BMI alterations and the prevalence of overweight (BMI ≥ 25) and obesity (BMI ≥ 30) after service durations of ≤2 years, 2−5 years, or ≥5 years. Between 2010 and 2022, we observed a trend for BMI increases of about 0.5 kg/m2 (X2 = 27.104, p = 0.007). BMI increases differed significantly (X2 = 7622.858, p < 0.001) after ≤2 years (0.0 kg/m2), after 2−5 years (1.1 kg/m2), and after ≥5 years (2.4 kg/m2) and were correlated to service duration (r = 0.34, p < 0.001). The prevalence of overweight increased from 33.0% to 39.5%. Obesity prevalence increased from 3.7% to 6.3%. The switch to obesity was more pronounced for longer service durations. Although secular trends for BMI increases among soldiers were in line with the general population, service duration was related to BMI increases. Especially, the service time depending on pronounced prevalence of obesity should be a matter of debate leading to counteracting measures at the German Armed Forces.
RESUMEN
In 2020, as part of the COVID-19 pandemic, governments around the world enacted a wide variety of regulations and laws to contain the incidence of infection. One of these measures was the relocation of work to the home office. The objective of this review was to analyze the influence of the home office in correlation with regulations on sedentary and activity behavior. A search was conducted on various electronic databases from November 2019 to January 2022, using the search terms physical activity (PA), COVID-19, and working from home. The primary outcomes were changes in PA and sedentary behavior (SB). Secondary outcomes included pain, mood, and parenting stress. The risk of bias was assessed using the (NHLBI) Quality Assessment Tool. For the review, 21 articles met the inclusion criteria (total n = 1268). There was a significant increase in SB (+16%) and a decrease in PA (-17%), Light PA (-26%), and moderate to vigorous PA (-20%). There was also an increase in pain and parenting stress and a decrease in well-being. Due to our significant results, programs that promote movement should be created. Future studies should explore how an increase of PA and a reduction of SB in the home office could be achieved.

INTRODUCTION: A wide variety of different types of wearable sensors are being developed around the world and introduced into the armed forces for military purposes. Competing states must rapidly develop ready-to-use systems that are robust, functional, valid, and practical. There appears to be potential for optimizing the successful and effective introduction of wearable sensors into the German armed forces (Bundeswehr) for military medical applications. The purpose of this study was to identify specific options for improving and optimizing the introduction of modern technologies such as wearable sensors into the structures of the German armed forces. MATERIALS AND METHODS: Nine stakeholders were identified who could provide a qualified statement on the introduction of wearable sensors, of which six agreed to participate in an expert interview. The six qualitative expert interviews, which were conducted for a master's thesis at the Bundeswehr University in Hamburg, were selected on the basis of their thematic involvement and readiness for an interview and provided the basis for exploring processes that can possibly optimize the introduction of wearable sensors into modern armed forces such as the Bundeswehr. These interviews were carried out and analyzed using the Lamnek's method. RESULTS: Six expert interviews were analyzed and the most relevant statements were summarized and presented. Thirteen options for optimization were identified and included, for example, interdisciplinary networking, optimization of information flow, and strategic weighting. CONCLUSIONS: Several potential options have been identified that can optimize the introduction of wearable sensors into the German armed forces to a greater or lesser extent. Bundeswehr experts agree that above all structurally relevant improvements such as "development of data analysis standards," "legal requirements," "interdisciplinarity," "acceleration of development," and "centralization and structured cooperation" should play an important role in the implementation of wearable sensors.

HISTORY AND CLINICAL FINDINGS: We report the case within a 22-year-old patient, initially seen because of fatigue, weight loss and discoloration of the skin. A Hashimoto-Thyroditis had been diagnosed a few months prior to the clinical presentation. DIAGNOSTICS: Blood samples showed a hyponatremia and hyperkalemia. Addison's disease was diagnosed by management of cortisol, ACTH and adrenal antibodies. In combination with the previously diagnosed Autoimmune thyreoiditis the criteria for a Schmidt's Syndrome were fulfilled. TREATMENT AND CLINICAL COURSE: We initiated the substitution of Hydrocortisone (20âmg/d) and Fludrocortisone (0.1âmg/d) in combination with an increased levothyroxin-dosage (100âµg/d). The patient's condition improved over the course of a few days. CONCLUSION: The presented case underlines the importance of focused examinations and diagnostics when dealing with a patient with unspecific symptoms and a pre-existing autoimmune disease. This also applies to patients with a positive family history for autoimmune disorders.

Anamnesis We report the case of a 57-year-old patient initially seen with stool irregularities and malignant ascites. Diagnostics Through further examinations we diagnosed a long standing untreated ulcerative colitis with endoscopic signs of a massive chronic inflammation of the entire colon. The origin of the malignant cells in the ascites remained unknown despite the exhaustion of all diagnostic means available. As an ultima ratio we performed a colectomy and an advanced adenocarcinoma of the appendix was found. Clinical course The patient's condition deteriorated very fast so that chemotherapy wasn't an option. Following his wishes he received palliative care in his home environment. Conclusion Patients with an inflammatory bowel disease have a higher risk of developing colorectal cancer. This is a well-known fact. But an adenocarcinoma of the appendix is still a rarity. Here we illuminate the possible link between the appendix and ulcerative colitis.
