The state of burnout is a nuanced condition primarily connected to enduring occupational stress, defined by emotional drain, disconnection from others, and a lesser feeling of personal competence. Identified by the World Health Organization as a critical concern within workplace, burnout is particularly widespread among healthcare professionals, attributed to rigorous workloads, bureaucratic obstacles, and inadequate support systems. This paper examines the underlying factors contributing to burnout- occupational, institutional, and individual aspects, and highlights the consequences for both healthcare providers and patient care. The analysis suggests that burnout adversely impacts both the psychological and physical health of medical workers and reduces the quality of patient care, consequently heightening systemic inefficiencies in the healthcare system. Furthermore, this research intends to delve into various individual, organizational, and systemic methods crafted to mitigate burnout, stressing the need for integrated interventions that cultivate resilience and advance well-being for healthcare practitioners. By examining the intricate aspects of burnout, this study aspires to impact policy and practice, consequently improving the standard of care and cultivating a healthier work environment in medical sector.

Background: The ability of hemoglobin to bind and dissociate oxygen is crucial in delivering oxygen to tissues and is influenced by a range of physiological states, compensatory mechanisms, and pathological conditions. This may be illustrated by the oxyhemoglobin dissociation curve (ODC). The key parameter for evaluating the oxygen affinity to hemoglobin is p50. The aim of this study was to evaluate the impact of hemodialysis on p50 in a group of patients with chronic kidney disease (CKD). An additional goal was to assess the correlation between p50 and the parameters of erythropoiesis, point-of-care testing (POCT), and other laboratory parameters. Methods: One hundred and eighty patients (106 male, 74 female), mean age 62.5 ± 17 years, with CKD stage G4 and G5 were enrolled in this cross-sectional study. Patients were divided into two groups, including 65 hemodialysis (HD) patients and 115 patients not receiving dialysis (non-HD). During the standard procedure of arteriovenous fistula creation, blood samples from the artery (A) and the vein (V) were taken for POCT. The causes of CKD, as well as demographic and comorbidity data, were obtained from medical records and direct interviews. Results: The weekly dose of erythropoietin was higher in HD patients than in non-HD patients (4914 ± 2253 UI vs. 403 ± 798 UI, p < 0.01), but hemoglobin levels did not differ between these groups. In the group of non-HD patients, more advanced metabolic acidosis (MA) was found, compared to the group with HD. In arterial and venosus blood samples, the non-HD group had significantly lower pH, pCO₂ and HCO₃⁻. This group had a higher proportion of individuals with MA with HCO₃⁻ < 22 mmol/L (42% vs. 24%, p < 0.01). The absolute difference of p50 in arterial and venous blood was determined using the formula Δp50 = (p50-A) − (p50-V). Δp50 was significantly higher in the HD group in comparison to non-HD (0.08 ± 2.05 mmHg vs. −0.66 ± 1.93 mmHg, p = 0,02). There was a negative correlation between pH and the p50 value in arterial (pH-A vs. p50-A, r = −0.56, p < 0.01) and venous blood (pH-V vs. p50-V, r = −0.45, p < 0.01). In non-HD patients, hemoglobin levels correlated negatively with p50 (r = −0.29, p < 0.01), whereas no significant relation was found in HD patients. Conclusions: The ODC in pre-dialysis CKD (non-HD) patients is shifted to the right due to MA, and this is an additional factor influencing erythropoiesis. Hemodialysis restores the natural differences in hemoglobin’s dissociation characteristics in the arterial and venous circulation.

Breathing is a fundamental physiological process essential for cellular respiration and energy production. Beyond its physiological necessity, controlled breathing techniques such as yogic breathing etc. pranayama, have been practiced for centuries due to their perceived spiritual and health benefits, including stress reduction and pain management. Recent studies have explored the physiological effects of deep slow breathing (DSB), particularly its impact on the autonomic nervous system (ANS) and pain perception. Evidence suggests that breathing at a low frequency, such as 6 h per minute (bpm), enhances heart rate variability (HRV), promotes parasympathetic activity, and reduces stress and pain levels.This review examines the mechanisms underlying these effects, highlighting the role of the vagus nerve in regulating relaxation and reducing inflammation. Empirical studies demonstrate that DSB positively influences chronic pain conditions, including menstrual pain and visceral pain, by modulating pain perception and emotional regulation. Additionally, the combination of DSB and vagus nerve stimulation (VNS) has shown promise in managing chronic pain and improving musculoskeletal pain thresholds. Despite promising findings in menstrual pain, visceral pain, and chronic conditions, further research is needed to elucidate the mechanisms and optimize breathing techniques for pain relief. However, while DSB and VNS have demonstrated potential in reducing pain and anxiety, current research is limited in scope and methodology. Further investigations are needed to establish their long-term benefits and optimize their use in pain management strategies. This review underscores the need for a deeper understanding of the connection between controlled breathing, vagal tone, and pain relief to support their clinical application.

Community-acquired pneumonia is a prevalent infectious disease with significant global morbidity and mortality. Atypical pneumonia, is characterized by milder symptoms and different pathogens, including Mycoplasma pneumoniae, Chlamydophila pneumoniae, and Legionella spp. Unlike typical pneumonia caused by Streptococcus pneumoniae and Haemophilus influenzae, atypical pneumonia presents with non-specific symptoms such as headache, fatigue, mild fever, and sore throat. Epidemiologically, atypical pneumonia constitutes over 15% of community-acquired pneumonia cases, with prevalence varying by region. It can be transmitted through aerosolized droplets, direct contact, or environmental exposure. Diagnostic challenges arise from inability of atypical pathogens to be detected via conventional Gram staining or culture techniques, it requires molecular assays like polymerase chain reaction and serological tests. Imaging, including X-ray, computed tomography, and ultrasonography, allow identifying characteristic lung abnormalities, yet their findings often overlap with other respiratory infections. Treatment strategies differ from those for typical pneumonia, as β-lactam antibiotics are ineffective against atypical pathogens due to lack of cell wall. Treatment recommendations include macrolides, tetracyclines, and fluoroquinolones. Complications of atypical pneumonia, though less frequent, can be severe, particularly in high-risk populations. Potential complications range from acute respiratory distress syndrome and cardiovascular conditions to neurological manifestations. Early diagnosis, coupled with targeted antibiotic therapy is essential to improve patients outcomes and reduce complications. This review provides a comprehensive overview of the etiology, clinical presentation, diagnostic challenges, treatment options, and potential complications of atypical pneumonia, emphasizing the need for continued research and improved diagnostic methodologies to enhance patient care.

Celiac disease (CD) is a chronic autoimmune disease triggered by the ingestion of gluten in genetically predisposed individuals, primarily those with HLA-DQ2 and HLA-DQ8 haplotypes. The global prevalence of CD ranges from 0.5% to 1%. Recent advances in diagnostic methods and raising awareness of this disorder have improved detection rates, but many cases remain undiagnosed due to the disease's multifaceted presentation. CD can manifest with a wide range of symptoms, including both gastrointestinal and extraintestinal signs. In smaller children common symptoms include mainly chronic or intermittent abdominal pain, abdominal distension, diarrhea and constipation. Older children and adolescent patients may frequently present atypical, vague symptoms such as fatigue, failure to thrive, weight loss, short stature, behavioral changes and anemia. Diagnosis involves primarily serological tests in patients presenting symptoms or in patients with high-risk of developing CD. A strict gluten-free diet is the principal treatment and it is highly effective in managing symptoms and promoting intestinal healing. In this paper, we will analyze epidemiology of CD, its pathogenesis, heterogeneous clinical presentation, the diagnostic process and treatment based on recent guidelines and literature.

Pressure injuries (PIs) represent a significant global health challenge, affecting approximately 10.8% of the European population in 2019. Their development is primarily attributed to ischemia and tissue necrosis resulting from prolonged pressure. According to the NPIAP classification, PIs are categorized into four stages, with surgical intervention predominantly indicated for stage III and IV ulcers. Reconstructive surgery encompasses various techniques, with debridement (the removal of necrotic tissue) being the most frequently performed procedure. An essential component of the healing process is negative pressure wound therapy (NPWT), which facilitates oxygen delivery to deeper tissue layers and promotes faster regeneration. Promising outcomes have also been observed with the use of regional flaps, particularly in the management of large bedsores and cases where other options are no longer viable. Despite advancements in surgical treatments, challenges such as graft rejection and high recurrence rates persist. The selection of the surgical approach should be guided by the patient’s overall health status and the specific characteristics of the ulcer. Effective management of PIs is critical for preventing prolonged hospitalizations and mitigating the risk of hospital-acquired infections, thereby significantly improving patients' quality of life.
