Restrictive Pulmonary Disease in Diabetes Mellitus Type II Patients.

Background The present study aimed to evaluate the proportion of restrictive pulmonary disease in individuals with diabetes mellitus type II patients. Methodology A cross-sectional study was performed at Liaquat University of Medical & Health Sciences between May 2020 and June 2021. All individuals aged between 40 and 65 years, irrespective of gender were included in the study. While those individuals with known obstructive lung diseases, blood disorders, or malignancy were excluded. Spirometry, total lung capacity (TLC), and carbon monoxide diffusing capacity (DLCO) measurements were conducted to obtain a pattern of restrictive disease in patients. Patients were divided into three main groups; i) prediabetes, ii) newly diagnosed cases of diabetes, iii) longstanding diabetes mellitus type II, and iv) control group. The parameters like the patients' age, sex, medication, history of smoking, and cardiac diseases, among other demographics were recorded. The data collected was recorded on a predesigned proforma. Results The majority of the newly diagnosed cases, as well as long-standing diseases, were elderly males (p=0.014 and p<0.0001). Dyspnea was significantly correlated with longstanding diabetes mellitus type II as indicated by a higher mean score of 0.65 ± 0.10 (p=0.006). Smoking did not significantly correlate with diabetes mellitus type II. In patients with longstanding diabetes, 27 (14.4%) had a modified Medical Research Council (mMRC) score of greater than two while none of the controls had severe breathlessness. Reduced forced vital capacity (FVC) was detected in 16.0% of patients with longstanding diabetes and 12.8% in patients with newly diagnosed disease. Similar results were obtained for total lung capacity (TLC) and diffusing capacity (DLCO) (p=0.003 and p=0.02). Conclusion Diabetes mellitus type II is significantly associated with restrictive lung disease in patients as indicated by a high number of patients with longstanding diabetes in our study who were found to have restrictive lung disease and severe dyspnea. Screening for lung dysfunction could aid in optimum management of this debilitating disease.

The behavior of neutrophil extracellular traps and NADPH oxidative activity in pediatric systemic lupus erythematosus: relation to disease activity and lupus nephritis.

OBJECTIVES: To evaluate the neutrophil extracellular traps (NETs) assay and NADPH oxidase (Nox2) activity in pediatric systemic lupus erythematosus (pSLE) in relation to each other and SLE characteristics. METHODS: This cross-sectional study included 50 children and adolescents with pSLE who were clinically evaluated and underwent routine laboratory work up of SLE (CBC, ESR, 24 hrs urinary proteins, serum creatinine, complement-3 (C3), anti-dsDNA, and antiphospholipid antibodies). NETs assay and dihydrorhodamine (DHR) test were done for patient group and 50 age- and sex-matched control group. RESULTS: The level of NETs was found significantly elevated among the patients (median 74.6 mU/ml) as compared to the controls (median 8.9 mU/ml) (p < 0.001), while values of DHR test were comparable between patients (median 95.5%) and controls (median 96.1%) (P = 0.55). There was a significant negative correlation between levels of NETs and DHR (p < 0.001). A significant positive correlation was noted between the 24 hrs urinary protein and NETs level (p < 0.001), but a significant negative correlation with DHR (p < 0.0001). Both NETs and DHR test values did not differ significantly between classes of lupus nephritis. NETs showed a significant positive correlation with anti-dsDNA titer (p = 0.004) and SLEDAI (p < 0.001), but a negative correlation with C3 (p < 0.001). DHR test was positively correlated with C3 levels (p = 0.003), but negatively correlated with anti-dsDNA titers (p = 0.008) and SLEDAI (p < 0.001). CONCLUSION: NETs seem to have strong association with biomarkers of pSLE activity. On the other hand, Nox2 activity of the neutrophils was noted to be linked to quiescent state of SLE. KEY POINTS: • Neutrophils have displayed different actions in pSLE through the NETs and Nox2 activity. • The inverse correlation between NETs and Nox2 activity makes the later a non-fundamental pathway for NETs formation. • NETs are associated with pSLE flare and LN activity, while neutrophil Nox2 activity is related to disease remission.

Relative Contribution of Obesity, Sedentary Behaviors and Dietary Habits to Sleep Duration Among Kuwaiti Adolescents.

The aim of this study was to investigate whether body mass index (BMI), eating habits and sedentary behaviours were associated with sleep duration among Kuwaiti adolescents. The study is part of the Arab Teens Lifestyle Study (ATLS), which is a school-based cross-sectional multi-center collaborative study. A sample of 906 adolescents (boys and girls) aged 14-19 years was randomly selected from 6 Kuwaiti Governances using a multistage stratified cluster sampling technique. The findings revealed that the prevalence of overweight and obesity was 50.5% in boys and 46.5% in girls. The majority of boys (76%) and of girls (74%) fell into the short sleep duration category (6 hours/day or less). Sleep duration were found to be negatively associated with BMI (girls only). Watching television (boys and girls) and working on computers (boys only) were also negatively associated with sleep duration. While the consumption of breakfast (both genders) and milk (boys only) was positively associated with sleep duration (p<0.05). In contrast, the consumption of fast foods (both genders), sugar-sweetened drinks and sweets (boys only) potatoes (girls only) were negatively associated with sleep duration (p<0.05). It can be concluded that the majority of Kuwaiti adolescents exhibit insufficient sleep duration which was associated with obesity measure, a combination of poor eating habits and more sedentary behaviors. The findings also suggest gender differences in these associations. Therefore, adequate sleep is an important modifiable risk factor to prevent obesity and was positively associated with some unhealthy lifestyle habits.

The impact of pulmonary hypertension on morbidity and mortality following major lung resection.

OBJECTIVES: Pulmonary hypertension is considered a poor prognostic factor for or even a contraindication to major lung resection, but evidence for this claim is lacking. This study evaluates the impact of pulmonary hypertension on morbidity and mortality following pulmonary lobectomy. METHODS: Adult patients who underwent a lobectomy for cancer and had a transthoracic echocardiogram (TTE) performed within the year prior to the operation were included. Pulmonary hypertension was defined as an estimated right ventricular systolic pressure (RVSP) of ≥36 mmHg by TTE. The preoperative characteristics, intraoperative data and postoperative outcomes of patients with and those without pulmonary hypertension based on TTE were compared. A model for morbidity including published risk factors as well as pulmonary hypertension was developed by multivariable logistic regression. RESULTS: There were 279 patients without pulmonary hypertension and 19 patients with pulmonary hypertension. Patients with pulmonary hypertension had a lower preoperative forced expiratory volume in 1 s and diffusing capacity of the lung for carbon monoxide than patients without pulmonary hypertension and a higher incidence of tricuspid regurgitation and mitral regurgitation, but the groups were otherwise similar. The mean RVSP in the group of patients with pulmonary hypertension was 47 mmHg. Perioperative mortality (0.0 vs 2.9%; P = 1.0) and postoperative complications (57.9 vs 47.7%; P = 0.48) were not significantly different between patients with and those without pulmonary hypertension. The presence of pulmonary hypertension was not a predictor of adverse outcomes in either univariate or multivariate analysis. CONCLUSIONS: Lobectomy may be performed safely in selected patients with pulmonary hypertension, with complication rates comparable with those experienced by patients without pulmonary hypertension.

Botulinum toxin: could it be an effective treatment for chronic tension-type headache?

Several clinical trials suggest that botulinum toxin type-A (BTX-A) may be an effective treatment option for patients with chronic tension-type headache (CTTH); however, controversy remains as to how the botulinum toxin optimally should be used for treating headache and which patient's profile fits this treatment. The objective of this study was to evaluate the efficacy and tolerability of BTX-A for the prophylactic treatment of CCTH in Egyptian patients. This was a randomized, single-blind, placebo-controlled study of BTX-A for the treatment of patients aged 25-50 years old with CCTH. Following a 30-day screening, headache parameters and severity assessed by the standard visual analogue scale (VAS), and the 25-item Henry Ford Hospital Headache Disability Inventory (HDI) were recorded as a baseline. Then, injection was done with either BTX-A or with saline by a combination of two methods for detecting injection sites (the fixed-site approach and follow-the-pain approach). Our study showed significant improvement after 1 month of BTX-A injection regarding headache days/month, severity measured by VAS and HDI in headache severity. There was significant reduction of prophylactic medications, and there were minor complications, but these reversed spontaneously without further treatment. BTX-A was an effective and well-tolerated prophylactic treatment in Egyptian patients with CCTH.
