About 20% of patients with systemic sclerosis have symptoms of another connective tissue disease (CTD). Interstitial lung disease (ILD) is one of the most common organ manifestations in systemic sclerosis (SSc) as well as viral illnesses, such as COVID-19, and can lead not only to diffuse alveolar damage, but also trigger an exacerbation of fibrosis among patients with preexisting ILD. It is also associated with substantial morbidity and mortality. According to the World Scleroderma Foundation, SSc-ILD can mask or mimic early COVID-19 lesions and there are no available computed tomography guidelines on how to discern those two conditions. We present a case of systemic sclerosis exacerbation after COVID-19 in a patient with SSc-Lupus Overlap Syndrome.

Acute pancreatitis is an inflammatory disorder of the pancreas associated with substantial morbidity and mortality, which is characterized by a rapid depletion of glutathione (GSH). Cysthionine-β-synthase (CBS) is a key coenzyme in GSH synthesis, and its deficiency is related to a variety of clinical diseases. However, whether CBS is involved in the pathogenesis of acute pancreatitis remains unclear. First, we found that CBS was downregulated in both in vivo and in vitro AP models. The pancreatic damage and acinar cell necrosis related to CBS deficiency were significantly improved by VB 12, which stimulated clearance of reactive oxygen species (ROS) by conserving GSH. Furthermore, EX-527 (a specific inhibitor of SIRT1) exposure counteracted the protective effect of VB 12 by promoting oxidative stress and aggravating mitochondrial damage without influencing CBS, indicating that vitamin B12 regulates SIRT1 to improve pancreatical damage by activating CBS. In conclusion, we found that VB 12 protected acute pancreatitis associated with oxidative stress via CBS/SIRT1 pathway.

COVID-19 outbreak has resulted in a substantial morbidity and mortality, and has put the health system under tremendous stress. A need for devising and adopting newer methods and techniques is being emphasized in the healthcare facilities to combat the effects of the SARS-CoV-2. Besides patient care, focus needs to be laid on the effective and dignified management of the deceased and medico-legal services provided by the hospitals and medical institutions during the COVID-19 pandemic. Considering the likelihood of forensic experts and autopsy personnel being exposed to SARS-CoV-2 inadvertently during the autopsy, it is recommended to resort to safer and minimally invasive techniques of postmortem examination of the dead. In this regard, employing radiological techniques for postmortem examination appears to be a promising option during the COVID-19 pandemic. An inherent advantage of postmortem radiography over conventional autopsies is the minimization of the risk of transmission of infection to the health care workers. Our correspondence highlights on the possibility of using radiological facilities as an effective replacement of high-risk conventional autopsy procedures during the COVID-19 pandemic.

Abstract Burn injuries are among the most traumatic incidences which could be associated with substantial morbidity and mortality. The incidence of these injuries differs based on population socioeconomic characteristics. In this study, we aim to evaluate the distribution of burn injuries based on socioeconomic and causative factors. Relative features from the targeted population were obtained and evaluated. Data were extracted in August 2019 and statistical analysis of the data was conducted from February 2020 to April 2020. This cross-sectional record-based study was conducted from 2008 to 2016 in a main referral center for burn injuries in the southern Iran. Participants included burn survivors and burn patients who were registered as outpatients or inpatients. A total of 4919 burn cases with a mean age of 31.91 ± 17.33, including 2926 (59.5%) males and 1993 (40.5%) females was reported. The majority of our cases had an educational level of under diploma (40.72%). A significant correlation between age, gender, and percentage of burn with the level of education was recorded (P < .001). The most frequent cause of burn injuries was flame with 2537 (51.9%) cases. The most susceptible population to burn injuries were reported to be poorly educated individuals, which emphasizes the preventive role of education.

Objectives. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an emerging virus causing substantial morbidity and mortality worldwide. We performed a cross-sectional investigation of SARS-CoV-2 clusters in Suzhou to determine the transmissibility of the virus among close contacts and to assess the demographic and clinical characteristics between index and secondary cases. Methods. We review the clustered patients with SARS-CoV-2 infections in Suzhou between 22 January and 29 February 2020. The demographic and clinical characteristics were compared between index and secondary cases. We calculated the basic reproduction number ( R 0 ) among close contacts with SLI model. Results. By 22 February, 87 patients with SARS-CoV-2 infection were reported, including 50 sporadic and 37 clustered cases, who were generated from 13 clusters. On admission, 5 (20.8%) out of 24 secondary cases were asymptomatic. The male ratio of index cases was significantly higher than that of secondary cases. Additionally, the index cases were more likely to have fever and increased CRP levels than the secondary cases. The R 0 values of clusters displayed a significantly declining trend over time for all clusters. The relative risk of infection in blood-related contacts of cases versus unrelated contacts was 1.60 for SARS-CoV-2 (95% CI: 0.42-2.95). Conclusions. In conclusion, SARS-CoV-2 has great person-to-person transmission capability among close contacts. The secondary cases are more prone to have mild symptoms than index cases. There is no increased RR of secondary infection in blood relatives versus unrelated contacts. The high rate of asymptomatic SARS-CoV-2 infections highlights the urgent need to enhance active case finding strategy for early detection of infectious patients.

The progression of diabetes leads to macro and microvascular complications, including diabetic neuropathy, which is the most prevalent microvascular complication with diabetes. Clinical manifestations of diabetic neuropathy begin with the loss of distal sensory function, pain, and substantial morbidity. It has been evident that ~50% of diabetic patients develop neuropathy at a certain stage in their lifetime. Interestingly, two major subtypes (type I and II) of diabetes do not share the same epidemiology and pathophysiology of diabetic neuropathy; thus, their management or treatment strategies may vary from each other. The past few decades of research suggest that many etiological features, diagnosis, and management complexities depend on the type of diabetes. However, the underlying mechanism of neuropathy in type I and type II diabetes remains unclear. This review provides the current knowledge on successful assessment, management, and pharmacological biomarkers to explore the treatment and surpass current challenges in diabetic neuropathy.

BackgroundInterstitial lung diseases (ILD) are diffuse parenchymal lung disorders that cause substantial morbidity and mortality. In patients with ILD, elevated antinuclear antibody (ANA) titers may be a sign of an autoimmune process. Inhalational exposures contribute to ILD pathogenesis and affect prognosis and may trigger autoimmune disease. The association of inhalational exposures with ANA seropositivity in ILD patients is unknown.MethodsThis was a retrospective cohort study of adult ILD patients from five US centers. Exposures to tobacco, inhaled organic antigens, and inhaled inorganic particles were extracted from medical records. A multivariable logistic regression model was used to analyse the effects of confounders including age, ILD diagnosis, gender, and exposure type on ANA seropositivity.ResultsAmong 1,265 patients with ILD, there were more ANA seropositive (58.6%, n=741) than ANA seronegative patients (41.4%, n=524). ANA seropositive patients had lower total lung capacity (69% versus 75%, p<0.001) and forced vital capacity (64% versus 70%, p<0.001) than patients who were ANA seronegative. Amongst patients with tobacco exposure, 61.4% (n=449) were ANA positive compared to 54.7% (n=292) of those without tobacco exposure. In multivariable analysis tobacco exposure remained independently associated with increased ANA seropositivity (OR=1.38, 95%CI=1.12–1.71). This significant difference was similarly demonstrated among patients with and without a history of inorganic exposures (OR=1.52, 95%CI=1.12–2.07).ConclusionPatients with ILD and inhalational exposure had significantly higher prevalence of ANA seropositivity than those without reported exposures across ILD diagnoses. Environmental and occupational exposures should be systematically reviewed in patients with ILD, particularly those with ANA seropositivity.

Severe invasive infections caused by group A Streptococcus (GAS) result in substantial morbidity and mortality in children and adults worldwide. Previously, GAS clonal strain replacement has been attributed to acquisition of exogenous DNA leading to novel virulence gene acquisition or increased virulence gene expression.
