Pneumonia and respiratory failure from swine-origin influenza A (H1N1) in Mexico.

National Institute of Respiratory Diseases, Mexico City, Mexico. perezpad@gmail.com
Abstract
BACKGROUND:

In late March 2009, an outbreak of a respiratory illness later proved to be caused by novel swine-origin influenza A (H1N1) virus (S-OIV) was identified in Mexico. We describe the clinical and epidemiologic characteristics of persons hospitalized for pneumonia at the national tertiary hospital for respiratory illnesses in Mexico City who had laboratory-confirmed S-OIV infection, also known as swine flu.
METHODS:

We used retrospective medical chart reviews to collect data on the hospitalized patients. S-OIV infection was confirmed in specimens with the use of a real-time reverse-transcriptase-polymerase-chain-reaction assay.
RESULTS:

From March 24 through April 24, 2009, a total of 18 cases of pneumonia and confirmed S-OIV infection were identified among 98 patients hospitalized for acute respiratory illness at the National Institute of Respiratory Diseases in Mexico City. More than half of the 18 case patients were between 13 and 47 years of age, and only 8 had preexisting medical conditions. For 16 of the 18 patients, this was the first hospitalization for their illness; the other 2 patients were referred from other hospitals. All patients had fever, cough, dyspnea or respiratory distress, increased serum lactate dehydrogenase levels, and bilateral patchy pneumonia. Other common findings were an increased creatine kinase level (in 62% of patients) and lymphopenia (in 61%). Twelve patients required mechanical ventilation, and seven died. Within 7 days after contact with the initial case patients, a mild or moderate influenza-like illness developed in 22 health care workers; they were treated with oseltamivir, and none were hospitalized.
CONCLUSIONS:

S-OIV infection can cause severe illness, the acute respiratory distress syndrome, and death in previously healthy persons who are young to middle-aged. None of the secondary infections among health care workers were severe.

a) The risk of infection was in young to mature persons
b) Some medical personnel were infected with influenza A (H1N1) virus (S-OIV)
c) The patients were treated in different hospitals
d) The patients were included in a retrospective study

Abstract
BACKGROUND:

The efficacy of influenza vaccines may vary from year to year, depending on a variety of factors, and may differ for inactivated and live attenuated vaccines.
METHODS:

We carried out a randomized, double-blind, placebo-controlled trial of licensed inactivated and live attenuated influenza vaccines in healthy adults during the 2007-2008 influenza season and estimated the absolute and relative efficacies of the two vaccines.
RESULTS:

A total of 1952 subjects were enrolled and received study vaccines in the fall of 2007. Influenza activity occurred from January through April 2008, with the circulation of influenza types A (H3N2) (about 90%) and B (about 9%). Absolute efficacy against both types of influenza, as measured by isolating the virus in culture, identifying it on real-time polymerase-chain-reaction assay, or both, was 68% (95% confidence interval [CI], 46 to 81) for the inactivated vaccine and 36% (95% CI, 0 to 59) for the live attenuated vaccine. In terms of relative efficacy, there was a 50% (95% CI, 20 to 69) reduction in laboratory-confirmed influenza among subjects who received inactivated vaccine as compared with those given live attenuated vaccine. The absolute efficacy against the influenza A virus was 72% (95% CI, 49 to 84) for the inactivated vaccine and 29% (95% CI, -14 to 55) for the live attenuated vaccine, with a relative efficacy of 60% (95% CI, 33 to 77) for the inactivated vaccine.
CONCLUSIONS:

In the 2007-2008 season, the inactivated vaccine was efficacious in preventing laboratory-confirmed symptomatic influenza A (predominately H3N2) in healthy adults. The live attenuated vaccine also prevented influenza illnesses but was less efficacious. (ClinicalTrials.gov number, NCT00538512.)





The primary objective of this study is to estimate the efficacy of two types of vaccines taking into account:

a) History of individual hypersensitivity to other vaccines component
b) The age and health status of elegibility
c) Randomization of vaccines
d) The study was performed from January throughout April


When do the vaccines under research were administered?

a) In the autumn season
b) When viruses A and B were present
c) The study was carried out in Massachusetts
d) The authors concern was about the f identification of the real-time polymerase-chain-reaction assay


How was determined the absolute efficacy in opposition of type A virus?

a) When the viruses were circulating during the influenza activity
b) When influenza virus A was 95 per cent CI
c) When the cultured virus was separated in culture
d) By the results of both vaccines



The conclusion of the study was as follows:

a) When one vaccine was effective and the other not as much as the other
b) That the efficacy of the vaccines were administered during the influenza season
c) The efficacy improved only in healthy male patients
d) The efficacy of influenza vaccines may vary from year to year, depending on a variety of factors

Risk factors for anastomotic leakage after laparoscopic intracorporeal colorectal anastomosis with a double stapling technique.
Kim JS, Cho SY, Min BS, Kim NK.

BACKGROUND:

Laparoscopic rectal transection carries the risk of anastomotic leakage because of its technical difficulty and long staple line with an inadequate cutting angle. Our objective was to investigate the risk factors affecting anastomotic leakage after laparoscopic intracorporeal colorectal anastomosis with a double stapling technique.
STUDY DESIGN:

Between November 2006 and September 2008, 270 consecutive patients underwent laparoscopic sigmoidectomy and anterior resection with double stapling technique for distal sigmoid and rectal cancer. Data were collected prospectively. Univariate and multivariate analyses were performed to determine risk factors for anastomotic leakage. Additionally, we evaluated the relationship between the number of stapler firings and clinical parameters.
RESULTS:

Anastomotic leakage was noted in 17 (6.3%) of 270 patients. In univariate analyses, tumor location (p = 0.021), operation time (p = 0.025), number of stapler firings (p = 0.040), and diameter of the circular stapler (p = 0.022) were significant risk factors for anastomotic leakage. Multivariate analyses showed that middle or lower rectal cancer was an independent factor affecting anastomotic leakage (p = 0.013). The number of stapler firings increased significantly in men (p = 0.023), in patients with a tumor at a lower level (p = 0.034), and in those with longer operation times (p < 0.001).
CONCLUSIONS:

A reduction in the number of linear stapler firings is necessary to avoid anastomotic leakage after laparoscopic colorectal anastomosis with a double stapling technique. We recommend that a diverting ileostomy is mandatory in patients with middle and lower rectal cancer where multiple linear staplers were used.




What is the technical complexity in the rectal transection?

a) The type of analysis performed
b) Extended staple row in addition to defective cutting edge
c) The double stapling technique
d) The anastomotic leakage


What was distinguished in a small amount of patients?

a) Number of stapler firings
b) Tumor location
c) An anastomotic leakage
d) A colorectal anastomosis






How was data accumulated?

a) It was collected prospectively
b) From patients with rectal cancer
c) By univariate analysis
d) By the amaount of risk factors


After the completion of the study the authors noted a…

a) Tumor location
b) A circular stapler
c) A need for less number of linear stapler firing
d) A diverting ileostomy

Abstract
BACKGROUND:

The prevalence of major depressive disorder (MDD) is highest in working age people and depression causes significant impairment in occupational functioning. Work productivity and work absence should be incorporated into clinical assessments but currently available scales may not be optimized for clinical use. This study seeks to validate the Lam Employment Absence and Productivity Scale (LEAPS), a 10-item self-report questionnaire that takes 3-5 minutes to complete.
METHODS:

The study sample consisted of consecutive patients attending a Mood Disorders outpatient clinic who were in full- or part-time paid work. All patients met DSM-IV criteria for MDD and completed during their intake assessment the LEAPS, the self-rated version of the Quick Inventory for Depressive Symptomatology (QIDS-SR), the Sheehan Disability Scale (SDS) and the Health and Work Performance Questionnaire (HPQ). Standard psychometric analyses for validation were conducted.
RESULTS:

A total of 234 patients with MDD completed the assessments. The LEAPS displayed excellent internal consistency as assessed by Cronbach's alpha of 0.89. External validity was assessed by comparing the LEAPS to the other clinical and work functioning scales. The LEAPS total score was significantly correlated with the SDS work disability score (r = 0.63, p < 0.01) and the Global Work Performance rating from the HPQ (r = -0.79, p < 0.01). The LEAPS total score also increased with greater depression severity.
CONCLUSION:

The LEAPS displays good internal and external validity in a population of patients with MDD attending an outpatient clinic, which suggests that it may be a clinically useful tool to assess and monitor work functioning and productivity in depressed patients.

Which of the assessment tools is mostly used?

a) QIDS-SR
b) LEAPS
c) HPQ
d) DSM-IV


According to the figures shown in the text, what could be the statistical meaning of them?

a) It showed high internal consistency
b) Low energy and motivation
c) The higher the score, the higher the intensity of depresion
d) Trouble with coworkers

How can work productivity be improved?

a) Provide incentive to employees
b) By its inclusion in clinical evaluations
c) Compare with other conditions that reduce productivity
d) Identify depression triggers at work


If LEAPS is a useful tool for assessing depression, it can also be used in

a) To monitor occupational functioning
b) To assess performance and productivity
c) To calculate the cost of a clinical trial
d) It can be used as an outcome for other clinical trials
