Objective: The aim of this study was to determine body composition, gynecological, and obstetric data, sex hormones, and prolactin serum levels in pre- (PREW) and postmenopausal women (PMW) with breast cancer (BC) and compare them with a control group (CG) of healthy women. Methodology: BC patients without treatment or use of hormone replacement therapy, or hormonal birth control, and without data of metastasis were included. CG was matched for age, BMI, and menstrual cycle status. FSH, LH, E2, progesterone, testosterone, and prolactin (PRL) were measured using radioimmunoassay kits. Comparisons between BC and CG were made with “t” tests, and with the Mann-Whitney U-test;χ2 test was used to compare the qualitative variables between the groups. Results: Seventy-two patients with BC, and 74 CG women were evaluated. Both groups presented overweight data, BMI (kg/mt2) = 27.21 ± 5.51 vs. 28.40 ± 4.66, p = ns, for BC patients and CG, respectively. In PREW, the age at menarche was later in BC patients compared to the CG (13.3 ± 1.36 years vs. 12.41 ± 1.27 years, p = 0.005). The PMW with BC presented a higher age at menarche and menopause compared to the women of the CG (13.51 ± 1.48 vs. 12.91 ± 1.41, p = 0.09, and 49.03 ± 2.86 vs. 45.5 ± 8.78, p = 0.03, respectively). PRL levels were significantly higher in PMW with BC, in comparison with the CG;median and minimum and maximum values (min-max) were: 14.7 ng/mL (3.6 - 52.7) vs. 5.9 ng/mL (1.9 - 33.3), p = 0.005). A higher percentage of PMW with BC (26.0% vs. 7.1%, χ2 = 5.57, p = 0.01) presented hyperprolactinemia (PRL serum levels > 20 ng/mL), compared to the GC. Conclusions: The higher levels of PRL in PMW with BC compared with CG, suggest a proliferative effect of this hormone in the affected breast tissue. This study demonstrates the need to use biological markers such as PRL to determine the risk of BC in PMW.

Plant-based antimicrobial agents are readily available, cost-effective, and exhibit low toxicity, making them promising alternatives in combatting microbial infections. Among these plants, garlic (Allium sativum) stands out for its traditional medicinal use in effectively combating various microorganisms. In the poultry industry, preventing avian virus and bacterial infections is paramount for chicken husbandry. However, using conventional drugs poses potential risks to human health. Garlic, a widely used Asian plant in traditional medicine for various pathologies, has shown potential as an herbal prophylactic remedy against viral and bacterial infections. Recently, researchers explored garlic and its derivatives as a scientific strategy in veterinary practices for diverse purposes, such as improving poultry production characteristics and acting as antibiotic growth promoters. This comprehensive review delves into garlic and its derivatives as preventive and corrective treatments for viral diseases in laying hens and broilers. The paper highlights their potential effectiveness and safety as a natural means to enhance poultry health and welfare while mitigating the risks associated with conventional drug usage in the food industry.

Surgical Science 2024年第9期15卷 514-521页

Introduction: Necrotizing pancreatitis management is complex and varies significantly among clinicians. Minimally invasive approaches like transgastric necrosectomy via laparoscopy are emerging as effective treatment options. This case report underscores the technique’s efficacy, clinical outcomes, and role in reducing complications. Clinical Observation: A 59-year-old male with a history of smoking and alcoholism presented with severe abdominal pain, nausea, and vomiting. Over the following weeks, he developed symptoms including asthenia, weight loss, and melena. Diagnostic workup revealed severe anemia and Balthazar E necrotizing pancreatitis, with significant intra-abdominal fluid collections and signs of infection. After initial conservative management, the patient underwent transgastric necrosectomy via laparoscopy due to deteriorating clinical status. The procedure involved removing necrotic tissue and performing a cystogastroanastomosis and jejunostomy. Postoperative care included fasting, parenteral nutrition, broad-spectrum antibiotics, and enzymatic replacement. The patient recovered well, with reduced necrotic tissue on follow-up imaging, and was discharged twelve days post-surgery [1]. Conclusion: Transgastric necrosectomy by laparoscopy is a valuable first-line surgical option for patients with symptomatic necrotizing pancreatitis, particularly in cases without prior interventions. This minimally invasive technique helps reduce major complications and mortality, offering a less invasive alternative to traditional open necrosectomy. The multidisciplinary approach and careful postoperative management were crucial to the patient’s favorable outcome. The case highlights the potential of transgastric necrosectomy as an effective treatment strategy in managing complex pancreatitis cases, including those with associated duodenal perforation [2].

AIM：To analyze the relationship between the score obtained in the Risk Score System（RSS）proposed by Hicks et al with penetrating keratoplasty（PKP）graft failure at 1y postoperatively and among each factor in the RSS with the risk of PKP graft failure using univariate and multivariate ***：The retrospective cohort study had 152 PKPs from 152 patients. Eighteen cases were excluded from our study due to primary failure（10 cases）,incomplete medical notes（5 cases）and follow-up less than 1y（3cases）. We included 134 PKPs from 134 patients stratified by preoperative risk score. Spearman coefficient was calculated for the relationship between the score obtained and risk of failure at 1y. Univariate and multivariate analysis were calculated for the impact of every single risk factor included in the RSS over graft failure at 1y. RESULTS：Spearman coefficient showed statistically significant correlation between the score in the RSS and graft failure（P〈0.05）. Multivariate logistic regression analysis showed no statistically significant relationship（P〉0.05）between diagnosis and lens status with graft failure. The relationship between the other risk factors studied and graft failure was significant（P〈0.05）,although the results for previous grafts and graft failure was unreliable. None of our patients had previous blood transfusion,thus,it had no impact. CONCLUSION：After the application of multivariate analysis techniques,some risk factors do not show the expected impact over graft failure at 1y.
