Introduction: Sleep disturbances are a common and often underestimated complication during intensive care unit (ICU) stays. These disturbances can significantly impact patients' recovery and overall well-being. This study aimed to assess the sleep quality of ICU patients and investigate the environmental and clinical factors that affect sleep quality during their ICU stay.

Methods: We conducted a six-month cross-sectional study involving patients who had stayed in the ICU for at least three nights and were oriented to time and place upon discharge. Sleep quality was assessed using the Arabic version of the Freedman Sleep Questionnaire. Both environmental factors (e.g., noise, light, and nursing interventions) and clinical variables (illness severity and pain) were examined. The differences across three time periods were analyzed using the Wilcoxon test and Spearman's correlation. Multiple regression analysis identified the factors influencing sleep quality. Statistical analyses were performed using JAMOVI software (version 2.3.28).

Results: The study enrolled 328 patients, with an average age of 49.74 ± 17.89 years. Of the participants, 75.3% were adults. The primary reasons for admission were circulatory distress (45.73%) and metabolic disorders (24.09%). Sleep quality was significantly lower in the ICU compared to patients' sleep at home (Z = -14.870, p < 0.001). The EVA and APACHE II scores had a statistically significant effect on sleep quality (p < 0.001 and p = 0.015, respectively). In contrast, the Charlson and Quick SOFA scores did not show significant effects (p = 0.128 and p = 0.894). Environmental factors, including noise (p = 0.008), light (p = 0.009), and nursing interventions (p = 0.009), significantly impacted sleep quality.

Conclusions: Patients in the ICU generally reported poor sleep quality. Our findings suggest that improving pain management, minimizing environmental noise, and reducing staff-related disturbances could significantly enhance sleep quality for patients in the intensive care unit (ICU).

Allergic rhinitis (AR) is a global health problem on the rise. More and more people are affected, and climate change is exacerbating this health problem in the long term. The quality of life of those affected is often severely compromised, and the financial burden on healthcare systems cannot be disregarded. Therefore, effective and safe medicines are needed to counteract this trend. P. hybridus (butterbur) leaf extract (Ze 339) displays a promising alternative to antihistamines in the treatment of AR symptoms. More than two decades after the first market launch it is now possible to draw a meaningful conclusion on its safety and efficacy. This review summarizes the available preclinical and clinical data, real-world data (RWD) as well as data from post-marketing pharmacovigilance monitoring about the herbal medicinal drug Ze 339. It focusses on the current knowledge about the mode of action as well as the evaluation of its efficacy and safety in the treatment of AR. Given its favourable safety profile and lack of sedative side effects, Ze 339 offers a valuable alternative to antihistamines and should therefore continue to be considered by medical practitioners for the treatment of allergic rhinitis symptoms.

Background: Depression and anxiety are common in patients with chronic respiratory diseases (CRDs), but their prevalence in intensive care settings, particularly in low-resource regions, remains underexplored.

Objective: To assess the prevalence and severity of depression and anxiety in patients with CRDs admitted to an intensive care unit (ICU) and identify associated factors.

Methods: A cross-sectional study was conducted at Gulab Devi Teaching Hospital, Lahore, Pakistan. Adult patients with CRDs admitted to the ICU were assessed using the Hamilton Depression Rating Scale. Statistical analyses included Fisher's exact test, Mann-Whitney/Kruskal-Wallis tests, and logistic regression.

Results: Depression was highly prevalent across all CRD categories: 83%, 89%, 84%, and 93% in obstructive, restrictive, infectious, and other respiratory disease categories, and severe depression in 16%, 18%, 14%, and 37%, respectively. Anxiety symptoms were also widespread (77-100%), with no significant differences across disease groups. Depression was significantly associated with older age (p < 0.001, OR 1.08) and anxiety symptoms (p < 0.001, OR 47.07). Female gender was linked to anxiety (p = 0.034, OR 4.17).

Conclusion: The high burden of depression and anxiety in ICU patients with CRDs underscores the need for routine psychiatric screening and integrated mental health care in critical-care settings.

Introduction: Idiopathic pulmonaryy fibrosis (IPF) is a progressive interstitial lung disease with a poor prognosis. While comorbidities like pulmonary hypertension and lung cancer have been studied extensively, less attention has been paid to the implications of malnutrition and sarcopenia in patients with IPF. This study aimed to assess the prevalence of malnutrition, sarcopenia, and the combined malnutrition-sarcopenia syndrome in patients with IPF using the latest diagnostic criteria from the Global Leadership Initiative on Malnutrition (GLIM) and the European Working Group on Sarcopenia in Older People 2 (EWGSOP2). Methods: A prospective, observational, multicenter study was conducted, focusing on patients with idiopathic pulmonary fibrosis (IPF). All participants provided informed consent, and the study followed ethical guidelines. Malnutrition was diagnosed based on the GLIM criteria, requiring one phenotypic and one etiological criterion, with muscle mass assessed via bioelectrical impedance analysis (BIA). Sarcopenia was screened following the EWGSOP2 recommendations. The statistical analysis was performed using JAMOVI version 2.3.22, with significance set at p < 0.05. Results: The findings revealed that 77.65% of the participants were malnourished, and 20% had sarcopenia. The malnourished patients had significantly lower body weight, height, and muscle mass compared to the non-malnourished patients. Furthermore, the patients with malnutrition exhibited poorer health-related quality of life scores. This study also identified the malnutrition-sarcopenia syndrome in 8.23% of the participants. Conclusions: Malnutrition, based on the GLIM criteria was identified in three out of four patients with IPF, while sarcopenia according to the EWGSOP2 was present in one out of five. This study underscores the necessity for routine screening for malnutrition and sarcopenia in patients with IPF.

Aim: This study aimed to evaluate the effects of inspiratory muscle training on inspiratory muscle strength and cardiorespiratory performance in patients undergoing open heart surgery.

Method: This study was conducted as a randomized controlled trial with two groups. Fifty-eight patients who underwent open heart surgery were randomly assigned to either the intervention group or the control group 29 in the control group and 29 in the intervention group. Patients in the intervention group participated in a physical therapy program combined with inspiratory muscle training using the Thammasat University (TU) Breath Trainer. Patients in the control group received only the standard physical therapy program. The maximum inspiratory pressure, maximum expiratory pressure and 6 min walk test distance were assessed both before surgery and prior to hospital discharge.

Results: The intervention group had a significant increase in maximum inspiratory pressure (p < 0.001), maximum expiratory pressure (p < 0.001) and 6 min walk test distance (p = 0.013). The control group had a significant decrease in maximum inspiratory pressure (p < 0.001), maximum expiratory pressure (p = 0.002) and 6 min walk test distance (p < 0.001).

Conclusions: Inspiratory muscle training can be performed using maximum pressure resistors, such as the TU-Breath Trainer device. This training has been shown to effectively improve inspiratory muscle strength and cardiorespiratory performance in patients undergoing open heart surgery, as well as reduce pulmonary complications and shorten the length of hospital stay.

There is limited research on the impact of a physiotherapy-guided rehabilitation program (PGRP) on lung structure in systemic sclerosis (SSc). Lung ultrasound (LUS) has been used for over a decade to identify interstitial lung disease associated with SSc (SSc-ILD). This study aims to evaluate the impact of a PGRP on LUS signals in women with SSc-ILD and women without ILD (SSc-wILD). This is a longitudinal quasi-experimental study that included 33 women with SSc. The results show that changes in LUS were observed in 22 participants, especially B-lines > two. Before the PGRP the median of B-lines > two was three (0-7), while after the PGRP it was three (0-6) (p = 0.020). The aeration score was eight (0-16.5) pre-PGRP and three (0-16) post-PGRP (p = 0.013). Analyzing the impact of the PGRP on LUS signals in SSc-ILD and SSc-wILD groups, the main change observed was a reduction in B-lines > two between pre-PGRP and post-PGRP in the SSc-ILD group (p = 0.0004). The SSc-ILD group had a higher aeration score than the SSc-wILD group both pre-PGRP (p < 0.0001) and post-PGRP (p = 0.0001)]. In conclusion, LUS may be a complementary tool for assessing pre- and post-PGRP changes in people with SSc-ILD and SSc-wILD. Our data also suggest that the PGRP can elicit measurable changes in LUS findings in SSc, particularly in SSc-ILD. These findings support the inclusion of LUS in the routine monitoring of SSc and the use of a PGRP as a non-pharmacologic adjunctive strategy in SSc.

Chronic Obstructive Pulmonary Disease (COPD) is a progressive respiratory disorder that poses significant challenges in treatment adherence. This systematic review evaluates the effectiveness of mobile health (mHealth) interventions compared to conventional therapy in improving treatment adherence among COPD patients. A total of 13 randomized controlled trials and comparative cohort studies published up to July 2023 were included, analyzing interventions such as medication reminders and remote monitoring in adult COPD patients. Studies involving participants under 18 years of age or with severe comorbidities were excluded. This review identified 4688 records from MEDLINE, WEB OF SCIENCE, and SCOPUS. Of these, 13 studies met the inclusion criteria. The selection process was conducted by two independent reviewers, with discrepancies resolved by consensus with a third reviewer. The results showed that mHealth interventions improved treatment adherence in some studies, particularly in exercise and symptom monitoring; however, the evidence was inconsistent, and results varied across studies. This review concludes that mHealth interventions have the potential to improve adherence but higher-quality studies and more robust designs are needed to confirm these findings and support their clinical implementation.

Introduction: Bronchopulmonary Neuroendocrine Neoplasms (NEN) occur in 2-7% of patients with multiple endocrine neoplasia type 1 (MEN1). Precursor lesions have been identified for MEN1-related pancreatic, duodenal, and gastric NEN. The aim of the current study using a MEN1 mouse model was to define the precursor lesions of bronchopulmonary NEN and evaluate the potential prophylactic antitumor effects of somatostatin analogues in a transgenic MEN1 mouse model.

Methods: Fifteen mice, germline heterozygous for Men1(+/T), were treated with subcutaneous injections of lanreotide autogel (Somatuline Autogel^®, IPSEN Pharma), while 15 mice were treated with subcutaneous injections of physiologic sodium chloride as the control group. Five mice from each group were euthanized after 12, 15, and 18 months, respectively. The complete lungs were resected and evaluated after hematoxylin and eosin staining and immunohistochemistry for synaptophysin and chromogranin A.

Results: In the lungs of the 30 evaluated mice, whether treated or placebo treated, no bronchopulmonary neuroendocrine cell hyperplasia nor neuroendocrine neoplasia was detected through histopathology. However, pulmonary adenocarcinoma developed in 2 (13%) of the 15 untreated mice and in 1 (7%) of the 15 lanreotide-treated mice.

Conclusions: Heterozygous Men1(+/T) knockout mice do not develop bronchopulmonary NEN or precursor lesions, but pulmonary adenocarcinoma. This surprising result needs to be investigated in more detail.

Background: Acute exacerbation (AE) of idiopathic pulmonary fibrosis (IPF) is one of the most challenging events in the disease course due to the high mortality despite treatment. The role of corticosteroid treatment in AE-IPF has never been defined, even though it is used in current clinical practice. We performed a meta-analysis to determine the effects of steroid treatment on the acute exacerbation outcomes in idiopathic pulmonary fibrosis (IPF). Objectives: To evaluate the impact of steroids on mortality in patients affected by an acute exacerbation of IPF. Methods: This meta-analysis was performed in accordance with the PRISMA statement. A systemic literature search was conducted through Google Scholar, Scopus, WoS, PubMed, and JSTOR. Manuscripts from January 2014 to September 2024 were included in the analysis. Articles were included on whether participants had an acute exacerbation of IPF. Regarding the intervention performed, we evaluated the studies in which patients underwent treatment with corticosteroids. As outcomes, studies were included if they analyzed the overall mortality. Results: A total of 2156 records were initially identified. Nineteen studies (3277 patients) were ultimately included in the final analysis, comparing 1552 patients who received steroids to 1725 patients without steroids. Steroid treatment poses a higher risk, as suggested by the summary measures (RR of 1.78; CI 1.29-2.76, p = 0.00001). Conclusions: This meta-analysis investigated the debated role of corticosteroid treatment during acute exacerbation of idiopathic pulmonary fibrosis. Overall, steroid therapy is associated with increased risk. Clinicians should carefully weigh the risks and benefits of corticosteroid therapy in acute exacerbation of IPF.
