Laparoscopy in Low-Income Countries: 10-Year Experience and Systematic Literature Review
2021
Laparoscopy is a procedure that ultimately reduces hospital stay time and speeds up post-operative recovery. It is mainly performed in high-income countries but its implementation in many low-and middle-income countries (LMICs) is increasing. However, no aggregate data exist regarding the outcomes of this procedure in resource-limited settings. We retrospectively reviewed all cases of laparoscopy recorded from January 2007 to March 2017 at the Department of Surgery of Beira to assess the related outcomes. Moreover, we performed a systematic review of the laparoscopic practices and outcomes in low-income countries. Data from the Department of Surgery of Beira identified 363 laparoscopic proc…
Meta-analysis of Randomized Controlled Trials and Individual Patient Data Comparing Minimally Invasive With Open Oesophagectomy for Cancer
2021
Minimally invasive oesophagectomy (MIO) for oesophageal cancer may reduce surgical complications compared with open oesophagectomy. MIO is, however, technically challenging and may impair optimal oncological resection. The aim of the present study was to assess if MIO for cancer is beneficial.A systematic literature search in MEDLINE, Web of Science and CENTRAL was performed and randomized controlled trials (RCTs) comparing MIO with open oesophagectomy were included in a meta-analysis. Survival was analysed using individual patient data. Random-effects model was used for pooled estimates of perioperative effects.Among 3219 articles, six RCTs were identified including 822 patients. Three-yea…
Epidemiology and social costs of hip fracture.
2018
Hip fracture is an important and debilitating condition in older people, particularly in women. The epidemiological data varies between countries, but it is globally estimated that hip fractures will affect around 18% of women and 6% of men. Although the age-standardised incidence is gradually falling in many countries, this is far outweighed by the ageing of the population. Thus, the global number of hip fractures is expected to increase from 1.26 million in 1990 to 4.5 million by the year 2050. The direct costs associated with this condition are enormous since it requires a long period of hospitalisation and subsequent rehabilitation. Furthermore, hip fracture is associated with the devel…
[Effect of flecainide on longitudinal and transverse conduction velocities in ventricular myocardium. An experimental study].
2007
It is known that the effect of flecainide on longitudinal and transverse ventricular conduction velocities depends on the coupling interval. If this is so, whether the longitudinal or transverse direction is predominantly affected could depend on the magnitude of the coupling interval. In order to investigate this hypothesis, we studied the effect of flecainide, 1 micromol/L, on conduction velocities in excised heart preparations from 11 rabbits using a basal cycle length of 250 ms and inserting two extrastimuli at a decreasing coupling interval. Flecainide significantly reduced both conduction velocities. However, the effect increased as the coupling interval decreased for only the longitu…
Factors Affecting Flutter Kicking Speed in Women Who Are Competitive and Recreational Swimmers
2009
The purpose of this study was to determine the relationships between possible predictive measures of a 50 m front crawl swimming and a 22.86 m flutter kicking speed. Ten women who were National Collegiate Athletic Association Division I collegiate swimmers and 10 women who were recreational swimmers (mean +/- SD = 20.6 +/- 1.6 years; 66.7 +/- 10.3 kg; 166.7 +/- 8.8 cm) volunteered for the study. Anthropometric measures were obtained including height, leg length, lower leg length, and foot length. Ankle flexibility was assessed by measuring ankle plantar flexion and ankle inversion. Lower body power was measured using a vertical jump. Swimming and kicking speed were measured as the time to c…
Distribution of Ha-ras alleles in patients with colorectal cancer and Crohn's disease.
1991
The allele distribution of the Ha-ras gene on chromosome 11p was analysed by the restriction fragment length polymorphism of the enzymes Mspl/Hpall in 238 individuals. The investigation covered 116 patients with colorectal carcinoma and 122 patients with Crohn's disease, representing two patient populations with the same ethnic origin, one with a malignant and the other a benign disease of the same organ system. A total of 17 different alleles were detected belonging to the common, intermediate, and rare classes according to the original nomenclature of Ha-ras alleles. Patients with Crohn's disease showed no difference in the distribution of Ha-ras alleles when compared with expected freque…
Role of comprehensive geriatric assessment in the management of osteoporotic hip fracture in the elderly: an overview
2013
Purpose: To highlight the advantages of comprehensive geriatric assessment (CGA) over usual care in the management of elderly patients with fragility hip fractures in terms of reducing the related mortality and disability. Method: An overview of publications on the topic was conducted using the MEDLINE and EMBASE databases. Results: Several models of geriatric and orthopedic comanagement have been developed in recent years, all characterized by a variable degree of integration, and they have been shown to reduce complications, disability and mortality in elderly hip-fracture patients. Preoperatively, CGA should identify the comorbidities that need to be treated in view of surgery, so as to …
Treatment of pulmonary hypertension in patients undergoing cardiac surgery with cardiopulmonary bypass: a randomized, prospective, double-blind study
2006
Pulmonary hypertension can already be present in patients undergoing cardiac surgery or can be exacerbated by cardiopulmonary bypass. Postoperative treatment is still a challenge for physicians. The aim of this study was to evaluate the effects of inhaled prostacyclin (iPGI2) and nitric oxide (iNO) compared with those of intravenous vasodilators.This prospective, randomized, double-blind study included 58 patients affected by severe mitral valve stenosis and pulmonary hypertension with high pulmonary vascular resistance (250 dynes x s x cm(-5)) and a mean pulmonary artery pressure25 mmHg. All patients were monitored by central venous, radial arterial and Swan-Ganz catheters. Data were recor…
Robotic Hysterectomy in Severely Obese Patients With Endometrial Cancer: A Multicenter Study
2015
Abstract Study Objective The aim of this study was to evaluate the surgical and oncologic outcomes of robotic hysterectomy with or without or less pelvic and aortic lymphadenectomy in severely obese patients (body mass index [BMI] ≥ 40 kg/m 2 ) with endometrial cancer. Material and Methods Between August 2010 and November 2014, patients with histologically confirmed endometrial cancer and BMI ≥40 kg/m 2 were deemed eligible for the study and underwent RH with or without pelvic and aortic lymphadenectomy. Results Seventy patients were divided into 3 groups according to their BMI: group A, BMI between 40 and 45 kg/m 2 (50 patients); group B, BMI between 45 and 50 kg/m 2 (10 patients); and gro…
