Predominance of ST22-MRSA-IV clone and Emergence of Clones for Methicillin-resistant Staphylococcus aureus clinical isolates collected from a Tertiary Teaching Hospital over a two-year period.

This study aimed to determine the genotypic and phenotypic characteristics of clinical MRSA isolates collected from a teaching hospital from 2014 - 2015. These isolates were genotyped by multilocus sequence typing (MLST), staphylococcal cassette chromosomal mec (SCCmec) typing, virulence genes detection and pulsed-field gel electrophoresis (PFGE) and phenotyped based on their vancomycin susceptibility profiles. The most prevalent sequence type was ST22. ST3547 was identified from a blood isolate from 2015. Three SCCmec types (III in 26.26%, IV in 70.71% and V in 3.03%) were detected. Agr type I, II, III were detected among the isolates. The most prevalent virulence genes were hemolysin (100%) and intracellular adhesion (91.9%). At least one staphylococcal enterotoxins was detected in 83 (83.8%) of the isolates. All of the isolates were susceptible to vancomycin (MIC ≤ 2 µg/ml). Statistical analysis revealed significant increase in hypertension (p = 0.035), dyslipidemia and obesity (p = 0.046), and previous exposure to any quinolone (p = 0.010) cases over the two-year period. Emergence and circulation of community-associated MRSA variants were observed in our hospital. PMID: 30814457 [PubMed - as supplied by publisher]

Conclusion. Patients with higher BMI had lower preoperative PROMIS PF scores and experienced similar improvement in PROMIS PF scores in the postoperative period. This study established that PROMIS PF may be utilized to evaluate the recovery of obese patients following MIS TLIF. Level of Evidence: 3

CONCLUSION: Patient, tumor, and bony pelvic anatomical characteristics are not seen to influence laparoscopic total mesorectal excision operative difficulty. Mesorectal area is identified as a risk factor for intraoperative and postoperative morbidity. See Video Abstract at http://links.lww.com/DCR/B35. FACTORES QUE PREDICEN LA DIFICULTAD OPERATIVA DE LA ESCISIÓN MESORRECTAL TOTAL LAPAROSCÓPICA ANTECEDENTES: La escisión mesorrectal total laparoscópica es un procedimiento desafiante. Para obtener resultados óptimos, se requiere cirugía de alta calidad. Se cree que, factores co...

Hypertension is possibly the most powerful, modifiable risk factor for the development of heart failure. Chronic hypertension drives cardiac remodeling within the left ventricle resulting in hypertensive heart disease, which ultimately manifests as heart failure. Early detection and appropriate management are necessary to prevent heart failure as well as other cardiovascular diseases. Achieving blood pressure goals in conjunction with using evidence-based treatments can improve clinical outcomes for patients with comorbid hypertension and heart failure.

Obesity has reached worldwide epidemic proportions, adversely impacting health on a global scale. Overweight and obesity adversely impact cardiac structure and function, affecting systolic and diastolic ventricular function. Studies and meta-analyses have documented an obesity paradox in large heart failure cohorts, where overweight and obese individuals with established heart failure have a better short- and medium-term prognosis compared with lean patients; this relationship is strongly impacted by level of cardiorespiratory fitness. There are implications for therapies aimed at increasing lean and muscle mass, and weigh...

Pulmonary hypertension (PH) often complicates chronic left-sided heart failure, with a remarkable impact on quality of life, exercise capacity, and survival. PH in chronic left-sided heart failure (PH-LHD) is not only caused by backward transmission of pressures but also involves impairment of atrial function, inflammation, and vasoconstriction. Once the left atrium loses its reservoir capacity, usually pulmonary vascular resistances increase. Right atrial dilation commonly represents the first sign of PH-LHD, before right ventricle dilatation and systolic dysfunction develop, leading to right heart insufficiency, and ulti...

The objectives of this retrospective study were to characterize hospitalized ABSSSI patients including comorbidities and identify the microorganisms associated with the infection. Methods Adults (>18 years) hospitalized with 1 or more primary ABSSSI diagnosis were selected from the Cerner Health Facts electronic medical records database between 2009 and 2013. Causative microorganisms for ABSSSI and Gram-stain type were identified from microbiology culture, including patients with methicillin-resistant Staphylococcus aureus (MRSA). Results Of the 11,705 patients identified, 51.8% were male, with a mean age of 55 ye...
