[Vitamin D and its positive effect on the PTH/vitamin D/calcium-FGF23/klotho/phosphorus axis in kidney transplant recipients].

Background: hypovitaminosis D is frequent in kidney transplant recipient (KTR) patients and is associated with deleterious effects both at the bone and extraosseous levels. Treatment with cholecalciferol is effective for the normalization of 25(OH)D, demonstrating a beneficial effect on the calcium-tropic axis in other populations; however, its effect on the PTH/vitamin D/calcium and FGF23/klotho/phosphorus axis in RTR has not been reported. The aim of this study was to evaluate the effect of normalization of serum 25(OH)D concentrations on the PTH/vitamin D/calcium-FGF23/klotho/phosphorus axis in KTR treated with cholecalciferol, as well as the association between the components of this axis.

Diagnostic accuracy of symptoms as a diagnostic tool for SARS-CoV 2 infection: a cross-sectional study in a cohort of 2,173 patients.

Background: The SARS-CoV-2 pandemic continues to be a priority health problem; According to the World Health Organization data from October 13, 2020, 37,704,153 confirmed COVID-19 cases have been reported, including 1,079,029 deaths, since the outbreak. The identification of potential symptoms has been reported to be a useful tool for clinical decision-making in emergency departments to avoid overload and improve the quality of care.

Establishing consensus on the perioperative management of cholecystectomy in public hospitals: a Delphi study with an expert panel in Mexico.

Background: Several guidelines have put forward recommendations about the perioperative process of cholecystectomy. Despite the recommendations, controversy remains concerning several topics, especially in low- and middle-income countries. The aim of this study was to develop uniform recommendations for perioperative practices in cholecystectomy in Mexico to standardize this process and save public health system resources.

High Serum Levels of High-Mobility Group Box 1 (HMGB1) and Low Levels of Heat Shock Protein 70 (Hsp70) are Associated with Poor Prognosis in Patients with Acute Pancreatitis.

Introduction: Cell damage in Acute Pancreatitis (AP) lead to release of cytokines and HMGB1 and Hsp70. While Hsp70 plays a role in cytoprotection, when released to extracellular milieu constitutes, as HMGB1, a danger signal and trigger pro-inflammatory responses. These molecules seem to be related to the clinical progression; but because no evidence exists about them as molecular network in AP development, we quantify HSP70, HMGB1, and cytokines in patients with AP and search for correlations with severity and prognosis.

No abstract.

Management of acute bacterial skin and skin structure infections with a focus on patients at high risk of treatment failure.

Over the last 25 years, the terminology of skin and soft tissue infections, as well as their classification for optimal management of patients, has changed. The so-called and recently introduced term 'acute bacterial skin and skin structure infections' (ABSSSIs), a cluster of fairly common types of infection, including abscesses, cellulitis, and wound infections, require an immediate effective antibacterial treatment as part of a timely and cautious management. The extreme level of resistance globally to many antibiotic drugs in the prevalent causative pathogens, the presence of risk factors of treatment failure, and the high epidemic of comorbidities (e.

[Acute appendicitis. Surgical and non-surgical treatment].

Appendicitis represents a common disease for the surgeon with a relative risk between 7-8%. It was thought that if more time passed between diagnosis and treatment, the risk for complications, such as perforation or abscess formation, was higher; nevertheless; the evolution is variable, making necessary the development of different strategies such as antibiotic use only, interval surgery or endoscopic treatment. The purpose of this study is to make a revision in the management of appendicitis comparing conservative and surgical treatment.

[Subclavian central venous catheter, complications at insertion].

Background: Central Venous Catheters (CVC) are used as a tool in critically ill patients requiring hemodynamic monitoring and vasopressor support, as well as in stable patients requiring parenteral nutrition or chemotherapy. Placement of a CVC subclavian (CVCs) can present severe complications, even fatal. The aim of the present study was to determine the success of the placement of CVCs without ultrasonographic guidance and the number and type of complications associated with insertion.

Effect of Oral ω3-Polyunsaturated Fatty Acids as a Complement Management to Control Fistula Output and Inflammation in Patients With Digestive Fistula.

Background: The presence of digestive fistula involves chronic inflammation and fibrosis. It has been reported that ω3-polyunsaturated fatty acids stimulate the resolution of inflammation.

[Obscure gastrointestinal bleeding due to gastrointestinal stromal tumors].

Background: The gastrointestinal stromal tumours (GIST) are the most common soft tissue sarcomas of the digestive tract. They are usually found in the stomach (60-70%) and small intestine (25-30%) and, less commonly, in the oesophagus, mesentery, colon, or rectum. The symptoms present at diagnosis are, gastrointestinal bleeding, abdominal pain, abdominal mass, or intestinal obstruction.
