Chronic obstructive pulmonary disease (COPD) is a disease state characterized by persistent respiratory symptoms and airflow obstruction determined by spirometry, including emphysema, chronic bronchitis, and small airway disease. Traditional treatment settings for COPD exacerbations typically involve in-hospital care. However, hospital-at-home (HaH) programs have emerged as an innovative model to provide hospital-level care at a patient's home. I synthesized available randomized controlled trials (RCTs) and compared the outcomes of COPD management in HaH and in-hospital settings. I searched for English language medical literature studies of COPD patients in HaH programs compared to in-hospital. Searches were performed in PubMed, EMBASE, Scopus, and CENTRAL. Outcomes were compared, meta-analyses were performed, and pooled odds ratios (ORs) and 95% confidence intervals (95%CIs) were calculated. Heterogeneity was evaluated and I² statistic was used to measure the proportion of inconsistency in individual studies. Potential publication bias was also calculated. Seven controlled studies representing 19 sub-studies (data sets) were selected according to the inclusion criteria. The OR of the HaH and in-hospital comparison was 0.542, 95%CI 0.379–0.774, P = 0.001. The different clinical outcomes of HaH were better or similar to those at regular hospitals, but with higher patient preference (OR 0.316, 95%CI 0.198–0.506). Heterogeneity and inconsistency were small, with no significant publication bias. HaH may be recommended for COPD patients' hospitalization when needed according to the specific indications and patients matching HaH criteria.

We presented the emergent development of pulmonary hypertension and right ventricular impairment in a 64-year-old woman with metastatic breast cancer undergoing carboplatin–gemcitabine combination therapy. The patient's acute decompensation, characterized by dyspnea and desaturation, occurred 2 days after chemotherapy initiation. Clinical assessments revealed right ventricular dilation and systolic dysfunction, a rare manifestation not previously associated with the administered drugs, but which may be associated with cardiopulmonary toxicity of gemcitabine therapy. Prompt discontinuation of chemotherapy and initiation of diuretic therapy resulted in clinical improvement and resolution of the right ventricular dysfunction within several weeks. While a definitive causal link to gemcitabine remains inconclusive, this report highlights a potential and under-reported side effect, emphasizing the need for increased awareness and further investigation into the cardiopulmonary effects of gemcitabine.

A full-term 1-month-old female was brought to our pediatric emergency department (ED) due to 3 days of increasing respiratory distress. She was born at term to healthy, consanguineous (2nd degree) Bedouin parents after a pregnancy that lacked adequate monitoring. At birth, a physical examination revealed an imperforate anus and a recto-vestibular fistula, left hydronephrosis, large patent ductus arteriosus (PDA), and an atrial septal defect (ASD). The diagnosis of VACTER association was made. Importantly, she had no respiratory difficulties, nor hemivertebra or tethered cord.

On admission to the ED, she presented with severe respiratory distress, tachypnea, dyspnea, and hypoxemia without evidence of upper airway obstruction or stridor. Due to impending respiratory failure, she was transferred to the pediatric intensive care unit and started on non-invasive respiratory support through a high-flow nasal cannula (HFNC), which partially relieved her work of breathing. The nasal swab for respiratory viruses was positive for enterovirus, and her urine culture grew Escherichia coli. She was transferred to the pediatric ward after clinical improvement on day 3. Echocardiography performed for evaluation of pulmonary hypertension estimated normal pressures but revealed a vascular ring anomaly. A computed tomography (CT) angiography performed confirmed the presence of an aberrant left pulmonary artery also referred to as a left pulmonary artery sling (LPAS) [Figure 1A].

Peripartum cardiomyopathy (PPCM) is an idiopathic cardiomyopathy presenting with heart failure (HF) secondary to left ventricular systolic dysfunction (defined as left ventricular ejection fraction [LVEF]) < 45% toward the end of pregnancy or in the months following delivery, where no other cause of HF is found. Complete understanding of the etiology is lacking, with higher incidence seen in advanced maternal age, multiple gestations, preeclampsia, and anemia [1]. Potential suggested causes include pathological immune response, hormonal abnormalities, stress cytokines, and nutritional deficiencies. Genetic predisposition was demonstrated in some PPCM, most commonly pathogenic loss-of-function truncating variants in Titin gene (TTN) [1]. Other causative genes reported are DMD, LAMP2, DSP, MYH6, SYNM, TPM1, and VCL [1].

A 69-year-old woman with a 30-year history of rheumatoid arthritis (RA) on leflunomide presented with dizziness and weakness. Vital signs, cardiopulmonary auscultation, and laboratory studies were normal. The serological status of her RA was unknown. She exhibited ulnar deviation and swan-necking of the hands but no nodular skin lesions. She was an active smoker. Chest radiography revealed an opacity in the right lung. Computed tomography (CT) showed multiple pulmonary nodules and a dominant thick-walled cavitary mass in the periphery of the right lower lobe [Figure 1A]. Due to concern for a malignancy or infection, she underwent a bronchoscopy with a biopsy of the mass, which was non-diagnostic. A subsequent transthoracic needle biopsy demonstrated a central zone of necrosis surrounded by a cuff of palisading epithelioid histiocytes with the presence of occasional giant cells [Figure 1B]. There was no malignancy, and stains for micro-organisms were negative. In this clinical context, biopsy results were consistent with a pulmonary rheumatoid nodule (PRN).

Background: Pulmonary aspiration is a potentially lethal perioperative complication that can be precipitated by gastric insufflation. Face mask ventilation (FMV), a ubiquitous anesthetic procedure, can cause gastric insufflation. FMV with an inspiratory pressure of 15 cm H₂O provides the best balance between adequate pulmonary ventilation and a low probability of gastric insufflation. There is no data about the effects of FMV > 120 seconds.

Objectives: To investigate the effect of prolonged FMV on gastric insufflation.

Methods: We conducted a prospective observational study at a tertiary medical center with female patients who underwent oocyte retrieval surgery under general anesthesia FMV. Pre- and postoperative gastric ultrasound examinations measured the gastric antral cross-sectional area to detect gastric insufflation. Pressure-controlled FMV with an inspiratory pressure of 15 cm H₂O was continued from the anesthesia induction until the end of the surgery.

Results: The study comprised 49 patients. Baseline preoperative gastric ultrasound demonstrated optimal and good image quality. All supine measurements were feasible. The median duration of FMV was 13 minutes (interquartile range 9–18). In the postoperative period, gastric insufflation was detected in only 2 of 49 patients (4.1%). There was no association between the duration of FMV and delta gastric antral cross-sectional area (β -0.01; 95% confidence interval -0.04 to 0.01, P = 0.31).

Conclusions: Pressure-controlled FMV with an inspiratory pressure of 15 cm H₂O carries a low incidence of gastric insufflations, not only as a bridge to a definitive airway but as an alternative ventilation method for relatively short procedures in selective populations.

Chronic obstructive pulmonary disease (COPD) is a common lung disease characterized by restricted airflow, changes of lung tissues, and breathing difficulties [1]. Most patients are treated at home to maintain a stable lifestyle and quality of life [2].

An important feature of COPD is exacerbation, which is an acute worsening of symptoms that can result in decreased pulmonary functions, increased risk of death, and poorer quality of life. The frequency and severity of each exacerbation results in further worsening of pulmonary function [3]. Depression in COPD patients may cause objective impairment in function and decreased adherence to therapeutic interventions [4].

Acute stress disorder is characterized by acute reaction in the first month following exposure to a traumatic event such as threatened death, serious injury, or sexual assault. Symptoms include intrusion, dissociation, negative mood avoidance, and arousal [5]. Stress on a more continuous basis can significantly debilitate a person's emotional and physical wellbeing, lead to depression and weakened immune system, and influence patients with already stressful and progressive conditions such as COPD.

We present a patient previously diagnosed with COPD who experienced an acute terror attack, which was a major and stressful event that caused severe exacerbation of the disease.

Metastatic pulmonary calcinosis (MPC) is characterized by deposits of calcium in normal pulmonary parenchyma. Diffuse pulmonary calcinosis commonly occurs in hypercalcemia and/or hyperphosphatemia and is more commonly related to renal failure than primary hyperparathyroidism, skeletal metastases, or multiple myeloma [1]. Calcium depositions favor alkaline tissue and are thus more common in the upper lobes of the lung, which have a higher ventilation to perfusion ratio and a low capillary pCO₂, resulting in an alkaline pH [2]. Therefore, the most common radiographic manifestation consists of poorly defined nodular opacities bilaterally in the upper lung zones [3].

Twenty years after being closed due to unfavorable results, a new lung transplant program was started at the Sheba Medical Center. The new team included an experienced lung transplant surgeon, an anesthesiologist, an intensive care specialist, and a pulmonologist with extensive experience in the field.

Pulmonary embolism (PE) is very common in cancer patients and is a marker of increased mortality in these patients. Treatment is associated with increased rates of recurrent thrombosis and bleeding and has undergone significant change in the last years with the increasing use of direct oral anticoagulants. Diagnosis of PE and risk stratification is possible with minor changes to existing risk scores. Thrombolytic therapy should be considered in appropriate patients.

Background: Venous thromboembolism (VTE) is a serious disease, which demands a fast accurate diagnosis to begin suitable treatment. It presents a major problem in the emergency department (ED), and its confirmation requires adequate evaluation.

Objectives: To evaluate a potential role of mean platelet volume (MPV) in differentiating VTE from other potential diagnosis in patients with suspected VTE.

Methods: We conducted a retrospective case-controlled study of 440 consecutive patients who presented to the ED of our hospital with clinical VTE, but only 316 with proven VTE. A control group was composed of patients (124) who presented with clinical VTE but without proven VTE. We checked the MPV value in all 440 patients and the correlation with VTE occurrence in the study group vs. control group.

Results: Statistical analysis of the acquired results indicated that MPV value could not aid in determining the difference of real VTE vs. patients with VTE-like clinical picture presenting to the ED. We found an inverse correlation between MPV value and proven VTE, in contrast to most researchers who have studied the same issue.

Conclusions: Although MPV can be a useful diagnostic marker in many diseases, we found no definite association between low MPV and VTE

Background: The coronavirus disease-2019 (COVID-19) pandemic had enormous impact on many aspects of our society, including huge medical, social, and economic challenges.

Objective: To evaluate the impact of the first wave of the COVID-19 pandemic and the related movement restrictions on the incidence of hip fractures in different age groups.

Methods: This single center retrospective observational study included all patients over 60 years old admitted to our hospital with the diagnosis of hip fracture during March and April 2020. Exclusion criteria were periprosthetic or pathologic fractures and multitrauma. We collected the same data on all patients with hip fractures admitted during March and April of 2018 and 2019.

Results: Mean patient age increased from 81.7 to 85.0 years. Only two of 49 patients tested positive for COVID-19. The data show a decrease of 38% in fracture load, but a striking decrease of 85% and 59% among sexagenarians and septuagenarian, respectively. There was no decrease among nonagenarians. Early mortality, both at 30 days and 90 days, was twice as common during the pandemic. However, stratification by age group demonstrated that the risks of early mortality were the same as previous years. Mean waiting time for surgery decreased from 27.5 to 18.9 hours. Patient discharge to home over a rehabilitation facility increased from 9% to 17%.

Conclusions: The COVID-19 pandemic affected the epidemiology of hip fractures in the elderly. The incidence of fractures and age distribution were significantly different from other years. Discharge destinations were also affected. The management of hip fracture patients was not compromised.
