A Rare Case of Shock in a Patient with Non-Severe Range Babesiosis

Babesiosis is a tickborne illness caused by microscopic parasites that infect red blood cells. Infections present on a spectrum from asymptomatic to severe, life-threatening presentations. However, life-threatening disease is more typically seen in patients who are asplenic, immunocompromised, or with hepatic/renal disease. We present an unusual case of babesiosis where an immunocompetent patient with age as the only risk factor, became extremely ill with relatively low parasite burden and no co-infection with other tickborne illnesses. A 73-year-old man with essential hypertension and remote prior Lyme disease infection presented to the hospital in late Spring due to acute mental status change after being found acting erratically by police. Upon presentation, he was hypotensive to 70/40 mmHg, tachycardic, and unable to follow commands. Blood parasite smear was positive for Babesia species with 2.2% parasitemia. Ehrlichia, Anaplasma and Lyme IgM species testing was negative. The patient required treatment of septic shock with norepinephrine. Along with azithromycin and atovaquone, he ultimately underwent three exchange transfusions due to significant hemolytic anemia. This led to dramatic improvement in his mental status and he was discharged with 10 additional days of antibiotics. Babesia infections present heterogeneously ranging from asymptomatic to life-threatening presentations with hypotension, hemolysis, thrombocytopenia, DIC, organ failure, and even death, especially in patients with risk factors. Our patient had a critical presentation without an immunocompromised state, no prior splenectomy, lack of liver/renal abnormalities, and relatively low parasitemia. Additionally, exchange transfusion can be considered with hemolysis despite non-severe range parasitemia

A case of atypical scleroderma renal crisis

We present the case of a 63-year-old female diagnosed with atypical SSc in the setting of acute SRC. She was undergoing work-up for progressive dyspnoea in the outpatient setting when she was found to have newly diagnosed restrictive lung pathology and worsening renal function, thus prompting acute hospital admission. Given multisystem involvement of the pulmonary and renal systems, the differential diagnosis included autoimmune and connective tissue disorders. Although serologies were non-specific, renal biopsy confirmed scleroderma renal disease, and she was started on treatment with captopril. This case highlights the importance of clinical judgment and timely diagnosis, even when laboratory data might indicate otherwise

Cytokine Gene Expression in the Maternal-Fetal Interface in Somatic Cell Nuclear Transfer Pregnancies in Small Ruminants

The present retrospective study investigates pregnancy rates, incidence of pregnancy losses and large offspring syndrome (LOS), and immune-related gene expression of sheep and goat somatic cell nuclear transfer (SCNT) pregnancies. We hypothesized that significantly higher pregnancy losses observed in sheep SCNT pregnancies compared to goats are due to the increased amounts of T-helper 1 cytokines and pro-inflammatory mediators at the maternal-fetal interface. Sheep and goat SCNT pregnancies were generated using the same procedure. Control pregnancies were established by natural breeding. Although SCNT pregnancy rates at 45 days were similar in both species, pregnancy losses between 45 and 60 days and incidence of LOS were significantly increased in sheep compared with goats. At term, the expression of pro-inflammatory genes in sheep SCNT placentas was increased while the one of goat SCNT was similar to the control animals. Among the genes that had altered expression in sheep SCNT placentas are CTLA4, IL2RA, CD28, IFNG, IL6, IL10, TGFB1, TNF, IL1A and CXCL8. MHC-I protein expression was greater in sheep and goat SCNT placentas at term compared with control pregnancies. An unfavorable immune environment is present at the maternal-fetal interface in sheep SCNT pregnancies

Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.

Heart Disease and Heart Failure: Trends and Disparities in Mortality Rates in the United States from 2000 to 2020

Study objective: To describe the age, sex and racial disparities in mortality rates for heart disease (HD) and heart failure (HF) in the United States (US) between 2000 and 2020. Design: This was an ecological study with trend analysis of mortality rates. Setting: United States. Participants: Adults aged 18 years and above. Main outcomes measures: Mortality rates per 100,000 for HD and HF. Results: There was a significant decrease in the age-standardized mortality rate for HD over the past two decades (from 343.5 per 100,000 cases to 215.1 per 100,000 cases, p \u3c 0.001). HD mortality rates were significantly higher in males (p \u3c 0.001), non-Hispanic blacks (p \u3c 0.001) and in adults aged 65+ (p \u3c 0.001) and 75+ (p \u3c 0.001). There was no significant change in the age-standardized mortality rate for HF (from 26.9 per 100,000 cases to 25.7 per 100,000 cases (p = 0.706)) due to a reversal in the trend beyond 2011. Though the HF mortality rates were significantly lower in males (p = 0.001), and not significantly different in non-Hispanic blacks and non-Hispanic whites, there were shifts in trends beyond 2016, with higher rates in males and in non-Hispanic blacks compared to non-Hispanic whites. Conclusions: In summary, this study underscores significant reductions in heart disease mortality rates over the past two decades, alongside persistent disparities among different demographic groups. It also highlights emerging trends in heart failure mortality rates in particular population subgroups in recent years, necessitating further exploration to inform targeted interventions and policies
