    Abstract Background: A significant proportion of Coronavirus Disease 2019 (COVID-19) patients require admission to the intensive care unit (ICU) and invasive mechanical ventilation (IMV). Tracheostomy is increasingly performed when a prolonged course of IMV is anticipated.
    Objectives: To determine clinical and resource utilization benefits of early versus late tracheostomy among COVID-19 patients.
    Methods: Pubmed, Cochrane Library, Scopus, and Embase were used to identify relevant studies comparing outcomes of COVID-19 patients undergoing early and late tracheostomy from January 1, 2020, to December 1, 2021.
    Results: Twelve studies were selected, and 2222 critically ill COVID-19 patients hospitalized between January to December 2020 were included. Among the included patients, 34.5% and 65.5% underwent early and late tracheostomy, respectively. Among the included studies, 58.3% and 41.7% defined early tracheostomy using cutoffs of 14 and 10 days, respectively. All-cause in-hospital mortality was not different between the early and late tracheostomy groups (32.9% vs. 33.1%; OR = 1.00; P = 0.98). Sensitivity analysis demonstrated a similar mortality rate in studies using a cutoff of 10 days (34.6% vs. 35.5%; OR = 0.97; P = 0.89) or 14 days (31.2% vs. 27.7%; OR = 1.05; P = 0.78). The early tracheostomy group had shorter ICU length of stay (LOS) (mean: 23.18 vs. 30.51 days; P < 0.001) and IMV duration (mean: 20.49 vs. 28.94 days; P < 0.001) than the late tracheostomy group. The time from tracheostomy to decannulation was longer (mean: 23.36 vs. 16.24 days; P = 0.02) in the early tracheostomy group than in the late tracheostomy group, but the time from tracheostomy to IMV weaning was similar in both groups. Other clinical characteristics, including age, were similar in both groups.
    Conclusions: Early tracheostomy reduced the ICU LOS and IMV duration among COVID-19 patients compared with late tracheostomy, but the mortality rate was similar in both groups. The findings have important implications for the treatment of COVID-19 patients, especially in a resource-limited setting.

    Abstract Systemic sclerosis (SSc) should be considered in all patients initially diagnosed with idiopathic interstitial lung disease (ILD), even in the absence of classical scleroderma cutaneous features. Systemic sclerosis sine scleroderma (ssSSc) is a rare subtype of SSc, and the diagnosis requires the absence of characteristic skin thickening but the presence of the three following criteria: (A) Raynaud's phenomenon or the equivalent of abnormal nail fold capillaries, (B) positive antinuclear antibody (ANA), typically with nucleolar or speckled immunofluorescence pattern, and (C) at least one internal organ involvement of ILD, renal dysfunction, esophageal/bowel dysmotility or pulmonary arterial hypertension; in the absence of an alternative rheumatological diagnosis. The radiological and histopathological features of systemic sclerosis sine scleroderma-associated interstitial lung disease (ssSSc-ILD) are commonly those of non-specific interstitial pneumonia (NSIP) and usual interstitial pneumonia (UIP) that cannot help distinguish between idiopathic interstitial pneumonia, different types of connective tissue diseases, or even different subsets of SSc. Therefore, other than chest imaging, the use of nail fold capillaroscopy, positive serum ANA antibody, echocardiogram, and esophagram are essential, in conjunction with the clinical presentation for facilitating the diagnosis of ssSSc. We present a case of a 58-year-old woman presenting with chronic dyspnea, a positive review of systems for Raynaud's phenomenon, and found to have elevated nucleolar immunofluorescence pattern of ANA with chest imaging consistent with the diagnosis of ssSSc-ILD. The uniqueness of this case is that despite symptomatic alleviation with oral mycophenolate therapy, our patient's restrictive lung disease on pulmonary function tests continued to decline, requiring initiation of oral nintedanib therapy leading to stability and improvement. However, due to the rarity of ssSSc, the use of oral nintedanib for systemic sclerosis-associated ILD has only been formally assessed on patients with diffuse cutaneous systemic sclerosis and limited cutaneous systemic sclerosis.

    Abstract Before coronavirus disease 2019 (COVID-19) emerged, proning had been demonstrated to improve oxygenation in those with acute hypoxic respiratory failure and be performed in non-intensive care settings. This benefit was further exemplified by the COVID-19 pandemic, leading to awake prone positioning (APP). We assessed the efficacy of routine APP versus standard care in preventing death and invasive mechanical ventilation (IMV) in non-intubated hypoxic COVID-19 patients. PubMed, Cochrane Library, Scopus, and medRxiv databases were used from January 1st, 2020, to January 15th, 2022, to identify randomized controlled trials (RCTs). Routine APP group were encouraged to be self-prone, whereas the standard care group received care according to local clinical practice and allowed APP crossover as rescue therapy. We included eight COVID-19 RCTs assessing 809 APP vs. 822 standard care patients. APP group had less IMV requirement (26.5% vs. 30.9%; OR - odds ratio 0.77; P=0.03) than the standard care group, with subgroup analysis showing greater benefit (32.5% vs. 39.1%; OR 0.75; P=0.02) for those mainly requiring oxygen support of non-invasive mechanical ventilation (NIMV) and high-flow nasal cannula (HFNC). The time to IMV initiation was similar (mean 8.3 vs. 10.0 days; P=0.66) for patients requiring NIMV and HFNC. Patients mainly receiving supplemental oxygen and non-rebreather masks had improved oxygenation parameters, although not statistically significant. Other outcomes involving all-cause hospital mortality, hospital and ICU (intensive care unit) length of stay, and adverse events were comparable. APP appeared to be an important modality for reducing IMV requirements, especially in those requiring NIMV and HFNC.

    Abstract Case presentation: A 50-year-old woman was seen in the office for recurrent episodes of cough and right-sided chest pain. She had visited the ED three times in the past 15 months for the same complaint. Each time, the pain started gradually affecting the right lateral chest wall. It was pleuritic and was associated with cough and mild shortness of breath. During these episodes, she reported low-grade fever but denied any night sweats, chills, sputum production, wheezing, or hemoptysis. She was treated with antibiotics and systemic steroids with resolution of her symptoms. The patient was an active smoker with a more than 35-pack year history. She had no known medical condition and was not taking any medication routinely at home. She had no family history of alpha-1 antitrypsin deficiency or Marfan syndrome.
