Objective: Investigating the relationship between physical activity (PA) and depressive symptoms is a vital field of research globally. Nonetheless, this association remains unexplored in the context of older Palestinian adults, highlighting the need for additional research on this population. Therefore, this study aimed to examine the association between PA and depressive symptoms among older Palestinian adults.

Subjects and methods: A cross-sectional study was conducted in the West Bank/Palestine with 266 participants. Data were collected using a PA socio-cultural adapted questionnaire (PA-SCAQ), the EuroQuol-5Dimensions-5Levels measure, and the Geriatric depression scale (GDS-15). Independent sample t tests and ANOVA tests were used to investigate mean differences in PA and GDS-15 scores between groups. Furthermore, multiple linear regression analysis was used to examine the relationship between study variables and the impact of the independent variable (PA level) on depressive symptoms.

Results: The mean age of the participants was 65.01 ± 8.02 years (range: 55-86), women 51.9%. Lower levels of PA and higher depressive symptoms were recorded among women, participants ≥65 years, and with recorded diagnosed disease (p < 0.05). The regression analysis showed a negative significant correlation between PA and GDS-15 scores (β = -0.235, p < 0.001), when controlling for age (model 2), and for age and sex (model 3), significant associations were recorded, respectively (β = 0.192, p = 0.002), and (β = 0.14, p = 0.015).

Conclusion: Participants who recorded higher depressive symptoms had a lower level of PA; regular moderate-intensity aerobic exercises can contribute to prevent depression symptoms in older adults.

Objectives: The objectives of this study were to determine the bacterial profiles and prevalence of antibiotic resistance patterns of bacteria causing bacteremia in febrile children and to compare levels of inflammatory markers between children with and without bacteremia in Kuwait from 2015 to 2022.

Materials and methods: Isolates from all episodes of significant bacteremia (n = 96) during the study period were recorded and evaluated. Microorganisms were identified using standard microbiological methods. Antimicrobial susceptibility testing was carried out using the VITEK2 system and Etest method. Extended-spectrum β-lactamase (ESBL) production by Enterobacterales was detected by the double-disk diffusion method and VITEK2 system. Patient age, gender, and inflammatory markers were collected at admission and compared between patients with and without bacteremia.

Results: A majority of the patients were infants (37, 40%) and newborns (13, 14%). The main ports of entry were the lower respiratory tract, the genitourinary tract, and the gastrointestinal tract. Streptococcus pneumoniae was the most common pathogen (16, 16.7%) followed by Escherichia coli (12, 12.5%), Staphylococcus aureus (10, 10.4%), and Streptococcus agalactiae (9, 9.4%). High rates of resistance to ampicillin, cefuroxime, ciprofloxacin, and trimethoprim-sulfamethoxazole were observed among the Enterobacterales. The prevalence of ESBL-producing E. coli and K. pneumoniae were 45% and 29%, respectively. The prevalence of methicillin-resistant S. aureus was 30%. Patients with bacteremia had significantly higher white blood cell (WBC) counts, absolute neutrophil count (ANC), C-reactive protein (CRP), and neutrophil-lymphocyte ratio (NLR).

Conclusion: Continuous surveillance of the prevalence and antimicrobial susceptibility patterns of blood isolates is imperative for the formulation of antibiotic policy. WBC, ANC, CRP, and NLR could be valuable indicators of bacteremia in febrile children.

Objective: Urinary incontinence (UI) is an involuntary leakage of urine and affects the social, physical, and psychological aspects of many individuals worldwide. The purpose of our study was to examine the prevalence, quality of life (QoL), severity, and different types of UI in overweight and obese women.

Methods: We conducted a cross-sectional study of 1,351 consecutive patients, who were recruited between June 2021 and May 2022.

Results: The mean age of the patients was 39.7 ± 14.2 years with less than a half in the 19-35-year age group (46.9%); 65% of the subjects were overweight or obese. The overall prevalence of UI was 61.2%. Overweight and obesity accounted to 70.2% of patients with mild to very severe UI. The risk estimates to have UI were 1.84 in overweight and 5.4 in obese group. The risk estimate for severe and very severe UI was 2.33 in overweight and 10.34 in obese group. When considering all subtypes, 67.9% of women with overweight and obesity had any of the subtypes, urge UI, stress UI, and mixed UI. Overweight and obesity were significantly associated with poor QoL in women with UI (p < 0.0001). Among 36.1% of all patients with poor QoL, 79.9% were overweight and obese.

Conclusions: Overweight and obesity are important risk factors of UI affecting daily activity and QOL considerably. As the number of people with obesity is increasing, the prevalence of UI with increased severity is likely to increase in young to mid-aged women. Weight loss should be considered as first-line treatment for this patient population.

Objectives: The contribution of pancreatic secretions in iron metabolism has been elucidated, but the clinical outcomes of iron deficiency on pancreatic function are debatable. This study aimed to investigate the modulation of euglycemic endocrine and exocrine pancreatic excretions in response to variations in iron availability.

Subjects and methods: Serum levels of insulin, glucagon, insulin-to-glucagon ratio (IGR), and amylase were determined in 170 adult subjects with variable levels of serum iron.

Results: Control (n = 46) and iron-deficient (n = 124) subjects had significant differences (p < 0.001) in their average levels of insulin (68.7 ± 0.5 vs. 100.0 ± 2.0 pmol/dL), glucagon (17.9 ± 0.6 vs. 10.8 ± 0.8 pmol/dL), IGR (4.0 ± 0.1 vs. 19.5 ± 2.1), and amylase (29.7 ± 0.9 vs. 17.5 ± 0.2). The upregulation of serum insulin levels increases proportionally and gradually to the extent of iron deficiency as compared to an abrupt downregulation of serum levels of glucagon and amylase. A significant association was observed between serum iron and IGR (r = -0.645, p < 0.001) and amylase levels (r = 0.653, p < 0.001). The receiver operating characteristic curve analysis defines an excellent predictivity of the reduced serum iron level to discriminate subjects with upregulated IGR and amylase levels with area under curves of 0.938 and 0.905, respectively.

Conclusion: Iron deficiency is associated with an adaptive modulation of euglycemic endocrine and exocrine secretions that is consistent with a status of insulin resistance.

Objective: Cannabinoid usage is widespread in the self-management of various medical ailments. However, adverse effects have been reported with use, especially pertaining to the gastrointestinal system in adults and aged patients. These range from nausea, vomiting, bloating, or abdominal pain. This systematic review of previously reported cannabis-induced gastrointestinal symptoms in the adult population from the literature provides an analysis of relevant data to enhance knowledge and awareness of this topic.

Methods: PubMed, Ovid MEDLINE, Cochrane Central, EMBASE, and Google Scholar databases were searched for relevant studies published from inception to March 2023.

Results: The search yielded 598 results, of which 13 were deemed relevant and underwent further review. These included two systematic reviews, one retrospective cohort study, one retrospective chart review, two cross-sectional studies, one survey, and six case reports. The Cochrane Risk Tool for bias analysis was applied where relevant. The total number of people in the studies selected for analysis was 79, 779. Twelve out of the thirteen included studies reported some type of gastrointestinal tract symptoms experienced in medical and/or recreational cannabis users ranging from nausea, vomiting, diarrhoea, abdominal pain to adult intussusception.

Conclusion: Potential limitations include small sample sizes, variation in research methodologies, varied studied designs, and limited availability of data on specific populations such as geriatric users. Further research is warranted to add to current evidence pertaining to this emerging topic of significance, fill the broad knowledge gaps and contribute to evidence-based guidelines for healthcare professionals, ensuring safe prescribing practices and provision of quality care.

Objectives: The incidence of soft tissue sarcomas (STSs) among older patients is increasing. Although surgical treatment of elderly patients with STS has been reported to improve their prognosis, most of these studies included patients with STS aged <85 years. This study aimed to analyze the clinical features and prognostic factors of STS in elderly patients aged ≥90 years.

Subject and methods: We retrospectively identified patients aged ≥90 years with STS who were treated at our two hospitals between 1994 and 2022. Data on clinical information and detailed assessments were collected. We evaluated the features and factors affecting the prognosis of patients with older-extremity STS. In addition, we compared the clinical courses and results of patients treated with surgery and radiotherapy for primary tumors.

Results: Among 454 patients with STS, 16 were aged ≥90 years. Kaplan-Meier curves for overall survival showed a significantly poorer prognosis in patients who did not receive surgical treatment (p = 0.0348) and those who received radiotherapy (p = 0.0070). Moreover, we investigated the difference in prognosis between surgical treatment and radiotherapy, excluding two cases with distant metastasis at initial diagnosis and one case with no treatment. Kaplan-Meier curves for overall survival showed a significantly better prognosis in patients who underwent surgical treatment (p = 0.0161). Univariate analysis revealed that only primary tumor size was a significant predictor of poor prognosis (p = 0.0426).

Conclusion: In patients with STS aged ≥90 years old, aggressive surgical treatment may improve the prognosis more than radiotherapy.

Objective: This study aimed to provide a comprehensive overview of the current state of the literature on the therapeutical application of bacteriophages.

Methods: First, a bibliometric analysis was performed using the database Web of Science to determine annual number of publications and citations. Second, a systematic literature review was conducted on randomized-controlled trials (RCTs) of phage therapy in PubMed.

Results: Over the past decade, the number of publications on bacteriophage therapy increased more than fourfold with 212 articles in 2011 and 739 in 2022. The systematic search in PubMed yielded 7 RCTs eligible for inclusion, reporting on a total of 418 participants. Identified indications in this study included bacterial diarrhea, urinary tract infections, infected burn wounds, chronic otitis, chronic venous leg ulcers, and chronic rhinosinusitis. In three studies, mild to moderate adverse events were reported in 10/195 participants (5.1%). Three of the studies reported a statistically significant difference in outcomes comparing phage therapy with standard of care or placebo.

Conclusion: Phage therapy has gained increasing interest over the years. RCTs on different indications suggest the safety of phage therapy; however, reasons why phage therapy is not yet well accepted are limitations in the study designs. For a successful translation into clinical practice researchers and clinicians should learn from the earlier experiences and consider issues such as the quality of phage preparation, sensitivity testing, titer and dosages, as well as access to the infection site and stability for standardized protocols and future trials.

Objective: Sepsis often prompts clinicians to start empirical antibiotics in suspected neonates while awaiting diagnosis. The next-generation testing with point-of-care (POC) techniques offers a lead-time advantage that could bridge the gap by providing a timely diagnosis.

Materials and methods: We conducted a prospective diagnostic study in 82 neonates enrolled between May and October 2022 in a level III neonatal intensive care unit. All neonates with a new episode of clinically suspected sepsis were included. Diagnostic accuracy of POC testing of C-reactive protein (CRP), interleukin-6 (IL-6), and procalcitonin (PCT) with standard laboratory methods was performed.

Results: The mean gestation age and birth weight of the neonates were 33.17 ± 4.25 weeks and 1,695.4 ± 700.74 grams, respectively. Most neonates were preterm (75%) with nearly equal proportions of early (51.22%) and late-onset (48.78%) sepsis. The POC CRP correlated well with standard CRP (r = 0.8001, 95% CI: 0.706-0.867, p < 0.0001). Among the three biomarkers, CRP had the maximum diagnostic accuracy (area under the curve [AUC] - 0.73) followed by PCT (AUC - 0.65) and IL-6 (0.55). There was no significant difference in the diagnostic accuracy of CRP (p = 0.46), PCT (p = 0.29), and IL-6 (p = 0.60) in early- and late-onset sepsis. The mean time for POC estimation of IL-6, PCT, and CRP was 12 ± 3 min which was significantly less compared to 366 ± 61 min for standard techniques (p < 0.001).

Conclusion: POC CRP correlates well with standard techniques of estimation, and CRP alone and in combination with PCT has good diagnostic accuracy in neonatal sepsis.
