With the limited availability of testing for the presence of the SARS-CoV-2 virus and concerns surrounding the accuracy of existing methods, other means of identifying patients are urgently needed. Previous studies showing a correlation between certain laboratory tests and diagnosis suggest an alternative method based on an ensemble of tests.
We have trained a machine learning model to analyze the correlation between SARS-CoV-2 test results and 20 routine laboratory tests collected within a 2-day period around the SARS-CoV-2 test date. We used the model to compare SARS-CoV-2 positive and negative patients.
In a cohort of 75,991 veteran inpatients and outpatients who tested for SARS-CoV-2 in the months of March through July, 2020, 7,335 of whom were positive by RT-PCR or antigen testing, and who had at least 15 of 20 lab results within the window period, our model predicted the results of the SARS-CoV-2 test with a specificity of 86.8%, a sensitivity of 82.4%, and an overall accuracy of 86.4% (with a 95% confidence interval of [86.0%, 86.9%]).
While molecular-based and antibody tests remain the reference standard method for confirming a SARS-CoV-2 diagnosis, their clinical sensitivity is not well known. The model described herein may provide a complementary method of determining SARS-CoV-2 infection status, based on a fully independent set of indicators, that can help confirm results from other tests as well as identify positive cases missed by molecular testing.

Disparities in access to screening often confound observed differences in HPV-associated genital tract cancer (FGTC) incidence between women living with HIV (WLWH) and their HIV-negative counterparts. We aimed to determine if there have been changes in cancer risk among WLWH during the anti-retroviral era in a single-payer health system.
We retrospectively selected WLWH and HIV-negative controls receiving care between 1999-2016 at the US Department of Veterans Affairs (VA) and identified FGTC diagnoses via Cancer Registry and ICD-9/10 codes. We extracted demographic and clinical variables from the VA's Corporate Data Warehouse; evaluated incidence rates (IR), incidence rate ratios (IRR), hazard ratios, and 95% confidence intervals (CI) for cancer risk; and conducted survival analyses.
We identified 1,454 WLWH and compared them to 5,816 matched HIV-negative controls. More WLWH developed HPV-associated FGTCs (total n=28 [2.0%]; cervical=22, vulvovaginal=4, and anal/rectal=2) than HIV-negative women (total n=32 [0.6%]; cervical=24, vulvovaginal=5, and anal/rectal=5) (log rank p<0.0001). Cervical cancer IR was >6-fold higher for WLWH (204.2 per 100,000 py [CI 83.8-324.7]) than HIV-negative women (IR = 31.2 per 100,000 py [CI 17.9-44.5]). The IRs for vulvovaginal and anal cancers were also higher in WLWH. Overall, WLWH were more likely to develop HPV-associated FGTCs compared to their HIV-negative counterparts (all log rank p values <0.0001).
Veteran WLWH are more likely to develop HPV-associated FGTCs despite equal access to health care. Even in single-payer health systems, WLWH continue to require special attention to ensure guideline-based high-risk HPV screening for prevention of FGTCs.

We aimed to study the prevalence of secondary antibiotic resistance of Helicobacter pylori in southern China and its risk factors, particularly geographical and socio-economic factors.
This was a municipality-wide, multicentre, prospective cohort study involving five major hospitals. Patients aged ≥18 years who failed first-line bismuth-based quadruple anti-H. pylori therapy between September 2016 and February 2018 were recruited. Participants underwent upper gastrointestinal endoscopy with biopsy from the antrum and body for H. pylori culture and antimicrobial susceptibility testing for six antibiotics (clarithromycin, levofloxacin, metronidazole, amoxicillin, tetracycline and furazolidone). Patients with failure of H. pylori culture were excluded. Participants completed a questionnaire profiling 22 potential risk factors of H. pylori infection and antibiotic resistance, including medical, social, household and birthplace factors.
A total of 1113 patients failed first-line therapy, with successful H. pigh in southern China. Certain population-level risk factors were associated with levofloxacin + metronidazole resistance.
The rates of secondary resistance of H. pylori to multiple antibiotics were high in southern China. Certain population-level risk factors were associated with levofloxacin + metronidazole resistance.The physiological stimulation of aldosterone production in adrenocortical glomerulosa cells by angiotensin II and high plasma K+ depends on the depolarization of the cell membrane potential and the subsequent Ca2+ influx via voltage-activated Ca2+ channels. Germline mutations of the low-voltage activated T-type Ca2+ channel CACNA1H (Cav3.2) have been found in patients with primary aldosteronism. Here, we investigated the electrophysiology and Ca2+ signaling of adrenal NCI-H295R cells overexpressing CACNA1H wildtype and mutant M1549V in order to understand how mutant CACNA1H alters adrenal cell function. Whole-cell patch-clamp measurements revealed a strong activation of mutant CACNA1H at the resting membrane potential of adrenal cells. Both the expression of wildtype and mutant CACNA1H led to a depolarized membrane potential. In addition, cells expressing mutant CACNA1H developed pronounced action potential-like membrane voltage oscillations. Ca2+ measurements showed an increased basal Ca2+ activity, an altered K+ sensitivity, and abnormal oscillating Ca2+ changes in cells with mutant CACNA1H.
