Meta Analysis
Effects of vitamin C supplementation on essential hypertension: A systematic review and meta-analysis.
Vitamin C as a supplement to treat hypertension has been proposed. However, it remains controversial whether vitamin C can improve blood pressure in patients with primary hypertension. ⋯ VitC supplementation resulted in a significant reduction of blood pressure in patients with essential hypertension.

The purpose of this study was to investigate the association of herpes zoster infection with peptic ulcer disease in a Korean population. The Korean National Health Insurance Service selects samples directly from the entire Korean population database, and 1,125,691 participants with 114,369,638 medical claim codes were selected from the entire Korean population (50 million). A total of 127,802 peptic ulcer disease participants were matched with 127,802 control participants at a ratio of 1:1, considering age group, sex, income group, region of residence, hypertension, diabetes, and dyslipidemia. ⋯ In subgroup analyses performed according to age and sex, all crude and adjusted hazard ratios of herpes zoster were higher in the peptic ulcer disease group than in the control group (each P < .05). In another subgroup analysis according to follow-up periods, the crude and adjusted hazard ratios of herpes zoster were higher in the peptic ulcer disease group than in the control group except for < 1 year periods after the index dates (each P < .001). The hazard ratios of herpes zoster were significantly increased in the peptic ulcer group compared with those in the control group in all age and sex groups.

Multicenter Study
Prevalence and predictors of peripherally inserted central venous catheter associated bloodstream infections in cancer patients: A multicentre cohort study.
Despite increasing use, the exact prevalence and predictors of peripherally inserted central catheter-associated bloodstream infection (PICC-CLABSI) in hospitalized patients with cancer are not elucidated. This retrospective cohort study included consecutive patients who underwent peripherally inserted central catheter (PICC) placement in 4 institutions (during 12 months in 3 hospitals and 10 months in 1 hospital). The prevalence of PICC-CLABSI was evaluated. ⋯ PICC for chemotherapy (hazards ratio [HR] 11.421; 95% confidence interval (CI), 2.434-53.594; P = .019), double lumen catheter [HR 5.466; 95% CI, 1.257-23.773; P = .007], and PICC for antibiotic therapy [HR 2.854; 95% CI, 1.082-7.530; P = .019] were associated with PICC-CLABSI. PICC for chemotherapy or antibiotics, and number of catheter lumens are associated with increased risk of PICC-CLABSI in cancer patients. Careful assessment of these factors might help prevent PICC-CLABSI and improve cancer patients care.

Observational Study
An acceptability pilot of the facilitating active management in lung illness with engaged surrogates (FAMILIES) study.
Approximately half of the surrogate decision makers of critically ill adults are at risk for negative emotional burden. Decision support and effective surrogate-clinician communication buffers against such experiences. The objective of this study is to evaluate the acceptability of a new surrogate-targeted educational tool that promotes engagement with clinicians and advocacy for 2 evidence-based practices in the provision of mechanical ventilation for acute respiratory failure: spontaneous awakening and breathing trials. ⋯ A significant number of previously unsure participants were able to identify what spontaneous awakening and breathing trials are and when they occur, and 16% to 36% reported significant improvements in their subjective understanding of the target evidence-based practices, after being exposed to the educational tool. This line of work seeks to reduce surrogates' negative emotional burden while also promoting quality critical care. The educational tool provides a promising new way to promote surrogate-clinician communication, by increasing surrogates' knowledge about and encouraging advocacy for evidence-based practices in the provision of mechanical ventilation.

Case Reports
Metastatic serous borderline tumor with micro-invasive ovarian carcinoma presenting as a breast lump: A case report.
Breast metastasis from serous borderline tumor with micro-invasive carcinoma of ovary is a very rare condition. The breast lump as the only clinical presentation is rarely seen in ovarian carcinoma, which may lead to be misdiagnosed, and the mechanism of breast metastasis from ovarian tumors in early stage still needs to be explored. Differentiation from primary breast cancer and extramammary malignancy is crucial because the treatment and prognosis are significantly different. ⋯ Distant metastasis may occur in early stage of ovarian carcinoma. It is important to determine the origin of the primary tumor and develop an effective treatment strategy for patients. Imaging findings and pathological diagnostic criteria are important to accurately differentiate between metastasis and primary breast lesions, which may improve the patient's outcomes.
