Antibiotic prophylaxis with sulbactam/ampicillin in colon surgery

We evaluated the effectiveness of sulbactam/ampicillin (S/A) as a perioperative prophylaxis regimen in elective colic surgery (procedures lasting less than 4 hours). We studied 18 patients (11 males, 7 females; mean age 46 yrs, range 21-72), by an open, non-comparative trial: S/A was given soon before anesthesia (1 g + 2 g) and the same dose was repeated every 6 hours, up to 5 doses. The drug was well tolerated, and there were no side effects requiring the interruption of the prophylaxis. Infection rate was low (only one case of evident suppuration of the wound).     

Prevalence and risk factors for Chlamydia trachomatis infection in adolescent females and young women in central Brazil

In order to determine the prevalence and risk factors for Chlamydia trachomatis infection in adolescent females and young women in central Brazil, 296 subjects attending two public health services were evaluated. The overall prevalence of C. trachomatis infection, as determined using polymerase chain reaction, was 19.6% (95% confidence interval [CI], 15.3–24.7). In multivariate analysis, young age (odds ratio [OR]_adjusted 2.32, 95%CI 1.1–4.8, p<0.05) and having 2–3 (OR_adjusted 3.41, 95%CI 1.6–6.3, p<0.05) or ≥4 sexual partners in life (OR_adjusted 3.10, 95%CI 1.1–6.3, p<0.05) were factors significantly associated with chlamydial infection. In conclusion, the prevalence of C. trachomatis infection was high in the studied population and risk factors were related to age and sexual behavior.     

Early and long-term prognostic factors after liver resection for HCC

The Authors discuss the principal early and long term predictive factors after liver resection in patients with hepatocellular carcinoma (HCC). The Authors report (131 cases) early mortality as 7.6%, entirely confined in the group, numerically prevalent and affected by cirrhosis. None of the 50 patients with chronic hepatitis (29 cases) or normal liver (21 cases) died after hepatic resection. Mortality is higher in Child B patients (20.7%) and in cases in which a massive haemotransfusion was given (p < 0.05), apart from the width of resection and from the number of hepatic resections. None of 41 cirrhotic Child A patients undergoing a limited hepatic resection (< or = 1 segment) died during the perioperative period. In the group of patients which survived to the resection, global survival at 5 years was 45%. The most important prognostic factor is local recurrence while cirrhosis and the degree of liver failure are not statistically significant. No feature can identify a subgroup of patients with a higher risk of recurrence, which is observed in 52% of patients with a follow up observation after more than 1 year. Among the 29 patients alive after more than 4 years from liver resection, only 11 didn't have local recurrence. The others were treated with iterative hepatic resections or with radiological techniques. In conclusion, the present experience suggests that, in selected cases, hepatic resection could be a low risk therapy (in cirrhotic patients as well). The long term results could improve with an aggressive attitude towards recurrence.     

Validation of the Sexual Inhibition/Sexual Excitation Scales (SIS/SES) in Italy: Assessing Gender and Age Differences of Sexual Functioning

The Sexual Inhibition Scales and Sexual Excitation Scales (Janssen et al., 2002a), based on the dual control model by Bancroft and Janssen (2000), are part of a 45-item self-report questionnaire evaluating individual tendencies to sexual inhibition or excitation according to three factors: two inhibition factors, SIS1, threat of performance failure, and SIS2, threat of performance consequences, and one excitation factor, SES. In this paper, we aimed to validate and explore psychometric properties of the SIS/SES in a sample of 2260 Italian men and women aged 18 to 75 years. Confirmatory factor analyses showed that the three-factor structure proposed in the original version of the scales fit with our sample. Moreover, our data confirmed the results of the original validation sample: Women scored higher on the SIS and lower on the SES than men did, but no significant differences appeared in the factor scores by age group, except for a gender × age interaction, where younger women had higher SIS2 scores. The SIS/SES appeared to be an effective, appropriate cross-cultural measurement of human sexuality in Italian samples, also shedding light on sexual arousal differences in women and men in our country. We also discuss clinical and therapeutic aspects.

     

Effectiveness of diaphragmatic stimulation with single-channel electrodes in rabbits

Every year, a large number of individuals become dependent on mechanical ventilation because of a loss of diaphragm function. The most common causes are cervical spinal trauma and neuromuscular diseases. We have developed an experimental model to evaluate the performance of electrical stimulation of the diaphragm in rabbits using single-channel electrodes implanted directly into the muscle. Various current intensities (10, 16, 20, and 26 mA) produced tidal volumes above the baseline value, showing that this model is effective for the study of diaphragm performance at different levels of electrical stimulation

Public Health Perspectives on Hearing Loss and Aging Outcomes: Preventive Care Utilization among Adults with Hearing Loss in the United States

Hearing loss (HL) can negatively impact patient–provider communication and limit access to health promotion information, which may lead to decreased preventive care utilization. Using data from the 2015 and 2018 National Health Interview Survey, we examined the association between perceived HL with and without hearing aid use with self-reported age-appropriate uptake of breast and colon cancer screening, and influenza and pneumococcal vaccination. In models adjusted for sociodemographic characteristics, access to care, and health status, people with HL had lower odds of receiving breast cancer screening (odds ratio [OR] = 0.83, 95% confidence interval [CI] = 0.72–0.96) and higher odds of receiving pneumococcal vaccination (OR = 1.11, 95% CI = 1.00–1.24) relative to those without HL. There were no differences in their colon cancer or influenza vaccination uptake. Compared with those without HL, people with HL who used hearing aids had increased odds of colon cancer screening and influenza and pneumococcal vaccination, while people with HL who did not use hearing aids were less likely to report cancer screening. Overall, Americans with untreated HL were less likely to report completing cancer screening. Hearing aid use may modify the association between HL and preventive care uptake. Screening for HL in primary care settings and communication trainings for providers may help reduce cancer screening disparities.     

Diagnostic yield of CT-guided lung biopsies: how can we limit negative sampling?

Objectives:To investigate whether lesion imaging features may condition the outcome of CT-guided lung biopsy (CTLB) and to develop a scoring system of biopsy outcome prediction.Methods:This is a single center retrospective study on 319 CTLBs that were performed in 319 patients (167 males/152 females, mean age 68 ± 12.2). Uni- and multivariate analysis were performed aiming to assess the imaging features that are likely to be correlated to a negative biopsy outcome and patients were stratified in groups accordingly.Results:Technical success was 100%. 78% of the biopsies (250/319) led to a concrete histology report (218 malignant/32 benign). The remaining lesions led to concrete histology at a second attempt that occurred on a later time. Multivariate analysis revealed increased risk of inconclusive result for nodules with low fludeoxyglucose uptake [odds ration (OR) = 2.64, 95% confidence interval (CI) 1.4–4.97; p = 0.003], for nodules with diameter smaller than 18 mm (OR = 2.03, 95% CI 1.14–3.62; p = 0.017) and for nodules that are located in one of the lung bases (OR = 1.96, 95% CI 1.06–3.62; p = 0.033). Three different groups of patients were identified accordingly with low (<30%), medium (30–50%) and high (>50%) probability of obtaining an inconclusive biopsy sample.Conclusion:This study confirms that percutaneous CT-guided biopsy in nodules that are either small in diameter or present low positron emission tomography-fludeoxyglucose uptake or are in one of the lung bases may lead to inconclusive histology. This information should be factored when planning percutaneous biopsies of such nodules in terms of patient informed consent and biopsy strategy.Advances in knowledge:Inconclusive histology after lung biopsy may be subject to factors irrelevant to technical success. Lung biopsy histology outcomes may be predicted and avoided after adequate planning.
