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 15months 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.

A previously healthy 47-year-old nonsmoking woman was admitted to our hospital with an 8-month history of progressive exertional dyspnea and fatigue. Chest high-resolution CT (HRCT) on admission showed diffuse, bilateral, patchy ground-glass opacity (GGO) (Fig 1A). She was diagnosed with interstitial lung disease, and corticosteroid therapy with 8weeks prednisone taper was completed, with initial good response. Eight months later, she was readmitted because of worsening of the dyspnea, with no fever, wheeze, dry cough, chest pain, weight loss, or hemoptysis. She denied a history of hair loss, skin rash, oral ulcers, or arthralgia. She denied a history of allergy or taking other drugs. She had no occupational or environmental exposures. There was no family history of respiratory diseases or hematologic diseases.

Although adult patients at advanced stage have been increasingly reported, there are few reports on clinical characteristics and pulmonary angiography (PAG) findings of early stage PPAS. We present two Japanese siblings with PPAS with homozygosity of RNF213 p.Arg4810Lys-one with advanced stage and the other with early stage. The latter case was an asymptomatic 37-year-old woman with mild PH. Notably, her PAG demonstrated nonthrombotic stenosis in the subsegmental branches of the pulmonary arteries with varying degrees of stenosis among lung segments. Taken together with a family history, genetic analysis, and cerebral angiography, the obtained images were considered as showing PPAS with early stage. This result is clinically informative to diagnose PPAS at an early stage and is also important to understand the pathogenesis of PPAS.Idiopathic pulmonary fibrosis (IPF) is a fatal interstitial lung disease characterized by progressive scar tissue formation. An acute exacerbation of IPF (AE-IPF) is a clinically significant respiratory decompensation that accounts for a significant proportion of IPF-related morbidity and mortality. AE-IPF can be idiopathic or associated with pulmonary embolism, infection, aspiration, surgery, and drug toxicity. In this novel case report, we describe a potential association between AE-IPF and BNT162b2 mRNA COVID-19 vaccination that was successfully treated with a short course of glucocorticoids. While our aim is to raise awareness for this yet-to-be-described adverse event, immunization against vaccine-preventable disease remains widely recommended in vulnerable patients with chronic lung disease such as IPF.
A 19-year-old, previously healthy man presented with 3days of cough, high-grade fevers (40 °C), and dyspnea. Apart from a resolved history of seizures not requiring medications, he had no medical or surgical history. He had no known drug allergies. He took montelukast for allergies and trimethoprim-sulfamethoxazole (TMP-SMX) for 2weeks before admission for acne, but no other medications, including over-the-counter medications and supplements. He had animal exposures to a new puppy and a friend's bird. He had no history of smoking, vaping, or recreational drug use. His paternal grandmother had rheumatoid arthritis.

An 85-year-old Japanese man, who was taking aspirin and edoxaban for previous myocardial infarction and atrial fibrillation, came to our hospital with a chief complaint of dyspnea for 3weeks. Chest radiography showed a massive left pleural effusion (Fig 1A). Analysis of pleural fluid showed an elevated hematocrit level at 32.8%(blood hematocrit level, 32.0%), and he was diagnosed with hemothorax. However, he had neither coagulation disorder nor thrombocytopenia, and the pleural effusion was negative for atypical cells. These findings suggested that the antithrombotic and anticoagulant medications might have induced the hemothorax.

In part two, we discuss the practical and ethical debates surrounding the exact timing of death. Although the irreversible cessation of cardiopulmonary systems remains the most common criteria used for the determination of death, identification of the moment of irreversibility is imprecise. In most cases, this imprecision is not problematic, but, when the cessation of circulation is used to identify the time of organ procurement for transplantation, it becomes critical. The phenomenon of autoresuscitation highlights these issues because patients who meet all the criteria for circulatory death (sometimes for periods of observation well beyond the norm) apparently return to life. Were these patients resurrected (like Lazarus) or did we simply not wait long enough?
Digital proximity tracing apps were rolled out early in the COVID-19 pandemic in many countries to complement conventional contact tracing. Empirical evidence about their benefits for pandemic response remains scarce. We evaluated the effectiveness and usefulness of COVIDSafe, Australia's national smartphone-based proximity tracing app for COVID-19.
In this prospective study, done in New South Wales (NSW), Australia, we included all individuals in the state who were older than 12 years with confirmed, locally acquired SARS-CoV-2 infection between May 4 and Nov 4, 2020. We used data from the NSW Notifiable Conditions Information Management System, the national COVIDSafe database, and information from case interviews, including information on app usage, the number of app-suggested contacts, and the number of app-suggested contacts determined by public health staff to be actual close contacts. We calculated the positive predictive value and sensitivity of COVIDSafe, its additional contact yield, and the numbled to a reduced sensitivity estimate in our study, given that only contacts who were using the app could be detected. COVIDSafe was not sufficiently effective to make a meaningful contribution to the COVID-19 response in Australia's most populous state over a 6 month period. We provide an empirical evaluation of this digital contact tracing app that questions the potential benefits of digital contact tracing apps to the public health response to COVID-19. Effectiveness evaluations should be integrated into future implementations of proximity contact tracing systems to justify their investment.

Vaccine effectiveness against COVID-19 beyond 6 months remains incompletely understood. We aimed to investigate the effectiveness of COVID-19 vaccination against the risk of infection, hospitalisation, and death during the first 9 months after vaccination for the total population of Sweden.
This retrospective, total population cohort study was done using data from Swedish nationwide registers. The cohort comprised all individuals vaccinated with two doses of ChAdOx1 nCoV-19, mRNA-1273, or BNT162b2, and matched unvaccinated individuals, with data on vaccinations and infections updated until Oct 4, 2021. Two outcomes were evaluated. The first was SARS-CoV-2 infection of any severity from Jan 12 to Oct 4, 2021. The second was severe COVID-19, defined as hospitalisation for COVID-19 or all-cause 30-day mortality after confirmed infection, from March 15 to Sept 28, 2021.
Between Dec 28, 2020, and Oct 4, 2021, 842 974 individuals were fully vaccinated (two doses), and were matched (11) to an equal number of unvaccinated individuals (total study cohort n=1 685 948).
