Sleep Habits and Disturbances Among Tunisian Adults: A Cross-Sectional Online Survey.

Background: Sleep quality and disturbances have gained heightened scholarly attention due to their well-established association with both mental and physical health. This study aims to assess sleep-wake habits and disturbances in Tunisian adults. Methodology: This cross-sectional study employed an online questionnaire to assess 3074 adults ≥ 18 years. Primary outcomes, including sleep quality, daytime vigilance, mood, and subjective well-being, were measured using validated questionnaires [the Pittsburgh Sleep Quality Index (PSQI), the Insomnia Severity Index (ISI), the Epworth Sleepiness Scale (ESS), the Patient Health Questionnaire (PHQ)-9, and the World Health Organisation-Five Well-Being Index (WHO-5)]. Results: Less than two-thirds (n= 1941; 63.1%) of participants were females and the mean age was 36.25±13.56. The prevalence of poor sleep quality was 53.8% when defined as a PSQI > 5. The prevalence of insomnia, short sleep duration, long sleep duration, EDS, severe depression, and poor well-being were 14.5%, 34.7%, 12.3%, 32.4%, 7.4%, and 40.2%, respectively. Some factors were associated with an increased likelihood of poor sleep quality, including female gender, chronic hypnotics use, internet use close to bedtime, daily time spent on the internet >3 hours, smoking, university- level education, nocturnal work, severe depression, impaired well-being status, insomnia, and EDS. Conclusion: The high prevalence of sleep-wake disturbances among Tunisian adults emphasizes the need for an appropriate screening strategy for high-risk groups. Individuals with unhealthy habits and routines were significantly more likely to experience these kinds of disturbances. Consequently, there is a pressing need for educational programs on sleep to foster healthier sleep patterns.

Sleep habits and quality among war and conflict-affected Palestinian adults in the Gaza strip.

OBJECTIVES/BACKGROUND: Sleep may be affected by traumatic experiences leading to an increased risk of poor quality of life and daily functioning. However, studies related to sleep habits and problems in conflict-affected areas are still sparse. The present study attended to describe sleep habits, estimate the prevalence rate of sleep disturbances, and identify associated factors in the Gaza strip. PATIENTS/METHODS: A population-based cross-sectional study including 1458 Palestinian adults aged ≥18 years living in the Gaza strip was carried out during the period between 18 February and March 31, 2022. An electronic survey through the free-of-charge Google Forms tool was used for data collection. A range of self-report measures related to sleep, mood, and subjective quality of life were used: the Pittsburgh Sleep Quality Index (PSQI), the World Health Organisation-Five Well-Being Index (WHO-5), the Epworth Sleepiness Scale (ESS), and the Patient Health Questionnaire (PHQ)-9. RESULTS: Three out of five of participants (n = 882, 60.5%) were females and the mean age was 34.8 ± 12.77 years. More than one-third of participants (n = 556, 38.1%) had poor well-being as assessed by the WHO-5 and 108 (7.4%) had a PHQ-9 score ≥ 20 indicating severe depression. The prevalence of poor sleep quality was 52.8% when defined as PSQI ≥ 6 and 30.5% when defined as PSQI ≥ 8. The prevalence of excessive daytime sleepiness (EDS), short sleep duration, severe depression, and poor well-being were 43.6%, 26.4%, 7.1%, and 38.1% respectively. Women and the youngest participants reached the highest prevalence rates for sleep and mood disturbance as well as for daytime dysfunction. Using multivariate binary logistic regression analysis, severe depression, being divorced, a history of psychological disease, poor well-being and previous war injuries were identified as the strongest predictors of poor sleep quality. CONCLUSION: Poor sleep quality, EDS, severe depression, and poor well-being in our sample were strikingly increased. Females and the youngest participants were the most affected. The conflict-affected situation in the Gaza strip combined with the high population density and worsening socio-economic conditions may play an important role in sleep disturbances, mainly because of a high prevalence of mood disturbances. Sleep and mood disturbances also adversely affect the quality of life.

Nonspecific interstitial pneumonia revealing an antisynthetase syndrome.

One of the most common interstitial lung diseases in antisynthetase syndrome is nonspecific interstitial pneumonia (NSIP). A 49-year-old woman presented with slow progression exertional dyspnea, myalgia, and arthralgia. The radiological findings indicated an NSIP pattern. Autoantibodies were found to be positive, but no lung biopsy was performed. Even though corticosteroid therapy significantly improved the patient's dyspnea, the patient developed mechanic's hands, the anti-synthetase antibody (PL12) became positive, and creatine phosphokinase (CPK) levels increased. As a result, the antisynthetase syndrome was established. The patient follow-up after three years revealed an improvement in symptoms under corticosteroid therapy.

Coronavirus disease 19 (COVID-19) and Cerebral venous sinus thrombosis (CVST): A case series and review of the literature.

A large proportion of patients with coronavirus disease 19 (COVID-19) suffer from excessive coagulation activation and coagulopathy which predisposes them to a wide spectrum of thrombotic events including in situ pulmonary thrombosis, deep-vein thrombosis, and associated pulmonary embolism, as well as arterial thrombotic events. Cerebral venous sinus thrombosis (CVST) have also been reported but in a very small number of cases. This report aims to increase awareness about CVST as a potential neurological thromboembolic complication in patients with coronavirus disease. We report three COVID-19 patients presenting with CVTS. We also review all previously described cases and present an overview of their demographic, clinical, and diagnostic data. We describe three patients with concomitant coronavirus disease and CVST among 1000 hospitalized COVID-19 patients (2 males, 1female, and mean age of 37 years). One patient was previously healthy, while the two others had a history of chronic anemia and ulcerative colitis, respectively. CVST symptoms including seizure in two patients and headache in one patient occurred day to weeks after the onset of COVID-19 symptoms. Three months of anticoagulant therapy was given for all three patients with favorable outcomes. No neurological sequelae and no recurrence occurred within 6 months after hospital discharge. Our search identified 33 cases of COVID-19 complicated by CVST. The mean age was 45.3 years, there was a slight male predominance (60%), and more than half of cases were diagnosed in previously healthy individuals. All cases of CVT were clinically symptomatic and were observed in patients with a different spectrum of coronavirus disease severity. Headache was the most common complaint, reported by just less than half of patients. There was a high mortality rate (30.3%). CVT is a very rare, but potentially life-threatening complication in patients with COVID-19. It's mainly reported in relatively young individuals with no or little comorbid disease and can occur even in patients who do not display severe respiratory symptoms. Atypical clinical presentations may pose a challenge to the early diagnosis and treatment. High suspicion is necessary as early diagnosis and prompt treatment with anticoagulation in all patients with COVID-19 and CVT could contain the mortality rate and improve neurological outcomes in these patients.

Characteristics of Obese Patients with Acute Hypercapnia Respiratory Failure Admitted in the Department of Pneumology: An Observational Study of a North African Population.

BACKGROUND: Acute hypercapnic respiratory failure (AHRF) is a common life-threatening event in patients with obesity hypoventilation syndrome (OHS). OBJECTIVES: To study the clinical pattern, noninvasive ventilatory support, as well as the short- and long-term outcomes of patients with OHS admitted in a ward because of AHRF. METHODS: We conducted a retrospective cohort study including all adults with OHS aged ≥ 18 - year - old, admitted in a 90-bed-ward for AHRF. RESULTS: A total of 44 patients were included. Fifteen (34.1%) and 29 (65.9%) patients were diagnosed with malignant OHS (mOHS) and nonmalignant OHS (non-mOHS), respectively, while 36 (81.8%) had coexisting obstructive sleep apnea hypopnea syndrome (OSAHS). Patients with mOHS had a significantly higher rate of heart failure (100% vs. 31%; p < 0.001), chronic renal insufficiency (CRI) (73.3% vs. 41.4%; p = 0.04), and dyslipidemia (66.7% vs. 34.5%; p = 0.04) than those with non-mOHS. The mean forced vital capacity (FVC) in our patients was of 59.5% ± 18.5 of the predicted value, lower than what is usually reported in stable patients with OHS. At hospital admission, more than two-thirds (n = 34, 77.3%) were misdiagnosed as having asthma exacerbation (n = 4, 4.9.1%), chronic obstructive pulmonary disease (COPD) exacerbation (n = 12, 27.3%) and/or heart failure (n = 29, 65.9%). Acute pulmonary oedema (ACPE) (n = 16, 36.4%) and acute viral bronchitis (n = 12, 27.3%) were the main identified causal factors, while no cause could be determined in 5 (11.4%) patients. Noninvasive positive pressure ventilation (NIPPV) using bilevel positive airway pressure (BIPAP) was very highly effective to treat AHRF, with only 2.27% of patients failing the modality. Median overall duration of ventilation was 9 hours per day (1.3-20) and was significantly longer in patients with mOHS than in those with non-mOHS (10 [6-18] vs. 8 [1.3-20], respectively; p = 0.01). Forty two of the forty-three patients discharged alive were treated with BIPAP or continuous positive airway pressure (CPAP) in 26 and 16 patients, respectively. The probability of survival was 90% at 12 months, while the probability of readmission for a new episode of AHRF was 56% at 6 months and 22% at 12 months, respectively. CONCLUSION: AHRF in OHS patients is a life-threatening event which can be successfully and safely treated with BIPAP, with a low long-term mortality even in patients with mOHS.

Clinico-radiological particularities of common pulmonary tuberculosis among smokers in Tunisia.

INRODUCTION: Smoking and tuberculosis are two major public health issues worldwide, particularly in emerging countries. Currently, the relationship between these two scourges is well established. AIM: Describe the clinical, radiological and progressive features of common pulmonary tuberculosis in smokers. METHODS: Comparative study, carried out at the Pneumology department of the Hédi Chaker in Sfax, Tunisia, including 120 patients hospitalized for common pulmonary tuberculosis  from January 2014 to December 2016 and who completed their follow-ups for a minimum period of 2 years . The patients were divided into 2 groups: Group1 (G1) consisting of 60 smoking patients and Group 2 (G2) consisting of 60 non-smoking patients. To assess the severity of radiological lesions, we used the International Labour Organization classification for simple pneumoconiosis and the Brouet classification. RESULTS: The mean age of the patients was comparable in the two groups with a predominance of male for G1 (91%) and female for G2 (70%). The smokers consulted later (113 days versus 60 days (p=0.023). Dyspnea, hemoptysis and chest pain were significantly more frequent in the smokers. The radiological lesions were more serious in smoking group. Bilateral lesions were more observed in smokers (58% vs 25% p = 0.004). A positive association was noted between the extent of radiological lesions, stage 3 and 4 according to the Brouet classification, and smoking status (p <0.001). Similarly for the International Labour Organization classification for simple pneumoconiosis , the radiological lesions were more severe (scores 6 - 15) in the smokers (p <0.001).Smoking was associated with poor adherence (p <0.008), prolonged anti-tuberculosis treatment (p <0.001), delayed RBK negativation in sputum (p <0.001), and more frequent reactivation of tuberculosis (p=0.001). After the diagnosis of CPT, 83% of patients continued to smoke at the same rate and only 7% of patients had quit smoking. CONCLUSION: Smoking worsens CPT by making the clinical picture noisier, radiological lesions more aggressive, negativation of BK in sputum later, and reactivation of CPT more frequent.

An isolated spontaneous pneumomediastinum as a rare complication of COVID 19.

The Coronavirus Disease 2019 (COVID-19) pandemic has displayed heterogeneity in disease manifestations and complications. This case report illustrates a rare issue : the spontaneous pneumomediastinum. A 73-year-old male presented with chills, and respiratory symptoms. A reverse transcriptase polymerase chain reaction (RT-PCR) test- confirmed COVID19. At admission, the patient was in severe respiratory distress. C reactive protein was 54 mg/l (normal: 0-5 mg/l), , troponin were negative, brain natriuretic peptid 55 pg/ml (normal range <100 pg/ml) and D-dimer 700 mcg/l (normal: 0-500 mcg/l). Arterial blood gases showed pH 7.49 (normal: 7.35-7.45), PCO2 33,8 mmHg (normal: 34-46 mmHg) and PO2 56 mmHg (normal: 80-97 mmHg) with 16 liter per minute of oxygen. Computed tomography of the chest (CT chest) showed diffuse groundglass opacities (60-70%) without pulmonary embolism. Diagnosis of acute respiratory distress syndrome (ARDS) was made. Low flow oxygen was provided (Oxygen saturation target ≥ 94%), intermediate dose of low molecular weight heparin and 8mg of dexamethason were administarted daily. On day 10, worsening hemodynamics and blood oxygen levels was noted. CT chest showed moderate bilateral pneumomediastinum, without pneumothorax, persistent groundglass opacities (75%) with early fibrosis elements. The patient recovered with no pulmonary sequelae. This case report encourages health workers to get used with infrequent clinical and radiological manifestations of COVID-19 that is still surprising the world.

Aortic thrombosis associated with COVID 19 pneumonia.

Coronavirus disease 19 (COVID-19) predispose to both venous and arterial thrombotic events, especially in severe patients. There are reports of lowe risk patients whose courses are complicated by arterial thrombosis. We report the case of 53 year-old woman who presented  with severe acute respiratory syndrome due to COVID-19 with descending aortic thrombosis. The evolution was favorable under anticoagulant treatment.

How does serum brain natriuretic peptide level change under nasal continuous positive airway pressure in obstructive sleep apnea-hypopnea syndrome?

BACKGROUND: Obstructive sleep apnea-hypopnea syndrome (OSAHS) is associated with cardiovascular morbidity and mortality, which can be improved by using continuous positive airway pressure (CPAP) therapy. However, the pathophysiological links between the two kinds of disease and the mechanism of the CPAP effect remain incompletely understood. We aimed to inquire into the myocardial involvement in this relationship. We suggested that serum brain natriuretic peptide (BNP) is sensitive enough to detect myocardial stress caused by OSAHS. DESIGN AND METHODS: Sixty-four subjects without cardiovascular disease (21 controls, 24 normotensive OSAHS patients, and 19 hypertensive OSAHS patients) were analyzed for serum BNP at baseline and serially over 6 months. CPAP was applied to 23 patients with severe OSAHS. RESULTS: At baseline, the serum BNP levels were significantly higher (p=0.0001) in the OSAHS group (22.3±14.79 pg/ml) than in the control group (9.2±6.75 pg/ml). Increased serum BNP levels were significantly associated with mean transcutaneous oxygen saturation (SpO2) (p<0.0001), minimal SpO2 (p=0.002), oxygen desaturation index (p=0.001), and total sleep time spent with SpO2 lower than 90% (p=0.002). All patients with elevated BNP levels (≥37 pg/ml) had moderate or severe OSAHS (11/43 OSAHS patients). The more severe the OSAHS, the higher the BNP levels were. However, only the difference between severe and mild OSAHS was statistically significant (p=0.029). Hypertensive OSAHS patients had the highest baseline BNP levels (27.7±16.74 pg/ml). They were significantly higher (p=0.001) than in normotensive OSAHS patients (18±11.72 pg/ml) (p=0.039) and the controls (9.2±6.75 pg/ml). As compared with baseline, treatment with CPAP significantly decreased BNP levels in both hypertensive and normotensive OSAHS patients (respectively, from 36±16.10 to 29.7±14.29 pg/ml, p<0.001, and from 20±10.09 to 16±8.98 pg/ml, p<0.001). In contrast, the BNP levels slightly increased in the controls (from 9.2±6.75 to 9.5±7.02 pg/ml, p=0.029), but there was no statistically significant difference in comparison with the baseline value. The effect of CPAP on BNP levels was more marked in patients with higher baseline BNP levels and those with the most prolonged nocturnal desaturation (p=0.001, r=0.65). It was also more marked in hypertensive OSHAS patients (p=0.015, r=0.72) in comparison with normotensive OSAHS patients (p=0.03, r=0.62). CONCLUSION: BNP seems to be sensitive enough to detect myocardial stress caused by OSAHS. As such, it is a potential marker for screening of preclinical cardiovascular damage in patients with untreated OSAHS. Application of CPAP decreases levels significantly in normotensive and particularly in hypertensive OSAHS. These findings are consistent with previous results suggesting the potential benefits of CPAP on cardiovascular outcome in OSAHS patients.

[A rare complication of generalized tetanus: pulmonary embolism]. / Une complication exceptionnelle du tétanos généralisé: l'embolie pulmonaire.

Tetanus is a disease characterized by spastic paralysis and spasms. It is a serious pathology that requires treatment in the ICU. Mortality rate is primarily due to neurodegenerative and infectious complications. Thromboembolic complications are rare. To the best of our knowledge, pulmonary embolism has never occorred and been confirmed in patients with generalized tetanus. Our study reports the case of a patient with generalized tetanus complicated by fibrin, cruoric pulmonary embolism.
