UK defence news, 1920-1938 : estimates based on contemporary sources

This paper employs the concept of ‘defence news’ proposed by Ramey (2009) to develop a time series of shocks to UK defence spending in the interwar period at a quarterly frequency. ‘Defence news’ is the present value of changes to defence spending plans. Information on this is taken from contemporary sources, in particular, The Economist. The estimates in this paper can be used as an input to assessing the size of the fiscal multiplier in interwar Britain as in Crafts and Mills (2012)

Did NAFTA Help Mexico? An Update After 23 Years

This paper compares the performance of the Mexican economy with that of the rest of the region and with its own economic performance, over the 23 years since NAFTA took effect, based on the available economic and social indicators. Among the results, it finds that Mexico ranks 15th out of 20 Latin American countries in growth of real GDP per person, the most basic economic measure of living standards; Mexico's poverty rate in 2014 was higher than the poverty rate of 1994; and real (inflation-adjusted) wages were almost the same in 2014 as in 1994. It also notes that if NAFTA had been successful in restoring Mexico's pre-1980 growth rate -- when developmentalist economic policies were the norm -- Mexico today would be a high-income country, with income per person comparable to Western European countries. If not for Mexico's long-term economic failure, including the 23 years since NAFTA, it is unlikely that immigration from Mexico would have become a major political issue in the United States, since relatively few Mexicans would seek to cross the border. This report updates a version released in February 2014

Benefit of viral load testing for confirmation of immunological failure in HIV patients treated in rural Malawi.

Objective  Viral load testing is used in the HIV programme of Chiradzulu, Malawi, to confirm the diagnosis of immunological failure to prevent unnecessary switching to second-line therapy. Our objective was to quantify the benefit of this strategy for management of treatment failure in a large decentralized HIV programme in Africa. Methods  Retrospective analysis of monitoring data from adults treated with first-line antiretroviral regimens for >1 year and meeting the WHO immunological failure criteria in an HIV programme in rural Malawi. The positive predictive value of using immunological failure criteria to diagnose virological failure (viral load >5000 copies/ml) was estimated. Results  Of the 227 patients with immunological failure (185 confirmed with a repeat CD4 measurement), 155 (68.2%) had confirmatory viral load testing. Forty-four (28.4%) had viral load >5000 copies/ml and 57 (36.8%) >1000 copies/ml. Positive predictive value was 28.4% (95% CI 21.4-36.2%). Repeat CD4 count testing showed that 41% of patients initially diagnosed with immunological failure did no longer meet failure criteria. Conclusions  Our results support the need for confirming all cases of immunological failure with viral load testing before switching to second-line ART to optimize the use of resources in developing countries

CD4+T cells and natural killer cells: Biomarkers for hepatic fibrosis in human immunodeficiency virus/hepatitis C viruscoinfected patients

To characterize peripheral blood natural killer (NK) cells phenotypes by flow cytometry as potential biomarker of liver fibrosis in human immunodeficiency virus (HIV)/hepatitis C virus (HCV) coinfected patients. Samples from 11 patients were included in G1 and from 13 in G2. All patients were on ARV, with undetectable HIV viral load. Liver fibrosis was evaluated by transient elastography in 90% of the patients and with biopsy in 10% of the patients. Mean HCV viral load was (6.18 ± 0.7 log10). Even though, no major significant differences were observed between G1 and G2 regarding NK surface markers, it was found that patients with higher liver fibrosis presented statistically lower percentage of NK cells than individual with low to mild fibrosis and healthy controls (G2: 5.4% ± 2.3%, G1: 12.6% ± 8.2%, P = 0.002 and healthy controls 12.2% ± 2.7%, P = 0.008). It was also found that individuals with higher liver fibrosis presented lower CD4 LT count than those from G1 (G2: 521 ± 312 cells/μL, G1: 770 ± 205 cells/μL; P = 0.035). Higher levels of liver fibrosis were associated with lower percentage of NK cells and LTCD4+ count; and they may serve as noninvasive biomarkers of liver damage.Fil: Laufer, Natalia Lorna.

Bronchial and arterial sleeve resection for centrally-located lung cancers

The use of bronchial and arterial sleeve resections for the treatment of centrally-located lung cancers, when available, has become the option of choice in comparison with pneumonectomy (PN). Technical expertise, in particular in vascular reconstruction, and perioperative management improved over time allowing excellent short-term and long-term results. This is even truer if considering literature data from the main experiences published in the last years. These evidences have given to such lung sparing reconstructive procedures more and more acceptance among the surgical community. This article focuses on the main technical aspects and literature data regarding bronchovascular sleeve resections

Contributing Factors to Under-Five Child Malnutrition in Rural Bangladesh

Background and objectives: Bangladesh has the highest malnutrition rates in the world. The main objective of this study is to identify and determine the main factors for child malnutrition among children under the age 5 years in rural Bangladesh. Material and methods: This research was conducted in rural areas at Meherpur district in Bangladesh. Convenience sampling method is used and 85 under 5 child information is collected through a structured questionnaire. The information’s of child’s are gathered from the mothers of the child. Malnourished children is measured by using APLS method and WHO Child Growth Standard Median Index. Binary logistic regression model is used to find out the key factors of malnutrition. Results: It is found that family income, maintain proper diet during pregnancy period, proper diet maintain for children have negative significant (p\u3c0.05) effect on child malnutrition. Conclusion: The magnitude of the child’s malnutrition still is of great concern in Bangladesh. Since, poverty, imbalanced diet during pregnancy period and imbalanced diet for under 5 children influences to malnutrition are significantly associated with high prevalence of malnutrition, so government and people should reduce these factor to reduce malnutrition in rural area of Bangladesh

An International Survey on Taking Up a Career in Cardiovascular Research: Opportunities and Biases toward Would-Be Physician-Scientists

Background Cardiovascular research is the main shaper of clinical evidence underpinning decision making, with its cyclic progression of junior researchers to mature faculty members. Despite efforts at improving cardiovascular research training, several unmet needs persist. We aimed to appraise current perceptions on cardiovascular research training with an international survey. Methods and Results We administered a 20-closed-question survey to mentors and mentees belonging to different international institutions. A total of 247 (12%) surveys were available (out of 2,000 invitations). Overall, mentees and mentors were reasonably satisfied with the educational and research resources. Significant differences were found analyzing results according to gender, geographic area, training and full-time researcher status. Specifically, women proved significantly less satisfied than men, disclosed access to fewer resources and less support from mentors (all P Conclusions Several potential biases appear to be present in the way training in cardiovascular research is provided worldwide, including one against women. If confirmed, these data require proactive measures to decrease discriminations and improve the cardiovascular research training quality

Variation in annual volume at a university hospital does not predict mortality for pancreatic resections.

Annual volume of pancreatic resections has been shown to affect mortality rates, prompting recommendations to regionalize these procedures to high-volume hospitals. Implementation has been difficult, given the paucity of high-volume centers and the logistical hardships facing patients. Some studies have shown that low-volume hospitals achieve good outcomes as well, suggesting that other factors are involved. We sought to determine whether variations in annual volume affected patient outcomes in 511 patients who underwent pancreatic resections at the University of California, San Francisco between 1990 and 2005. We compared postoperative mortality and complication rates between low, medium, or high volume years, designated by the number of resections performed, adjusting for patient characteristics. Postoperative mortality rates did not differ between high volume years and medium/low volume years. As annual hospital volume of pancreatic resections may not predict outcome, identification of actual predictive factors may allow low-volume centers to achieve excellent outcomes
