The media is the most popular vehicle through which consumers receive nutrition information, and is powerful in influencing food selection and health behaviors. Unfortunately, media messages surrounding nutrition are often inconsistent, confusing, and do not enable the public to make positive changes in health behaviors. The process to improve this scenario begins with communication between scientists and journalists. Scientists can take several steps to insure the results of their research are reported to the public accurately and, thereby, contribute to the achievement of the nation's public health goals.     

Changes in sputum cytology,airway inflammation and oxidative stress due to chronic inhalation of biomass smoke during cooking in premenopausal rural Indian women

To perform sputum analysis for verification of pulmonary changes in premenopausal rural Indian women chronically exposed to biomass smoke during cooking.Three consecutive morning sputum samples were collected from 196 women (median age 34 years) cooking with biomass and 149 age-matched control women cooking with cleaner fuel liquefied petroleum gas. Smears made on slides were stained with Papanicolaou and Perl's Prussian blue. Airway oxidative stress was estimated as reactive oxygen species (ROS) generation (by flow cytometry) and superoxide dismutase (SOD) level (by spectrophotometry) in sputum cells. Airway inflammation was measured as sputum levels of interleukin (IL)-6, -8 and tumor necrosis factor- alpha (TNF-α). Particulate matter of diameter less than 10 (PM₁₀) was measured using laser photometer while benzene exposure was monitored by measuring trans, trans-muconic acid (t,t-MA) in urine by HPLC-UV. Compared with control, sputum of biomass users contained more neutrophils, lymphocytes, eosinophils, alveolar macrophages, and showed presence of ciliocytophthoria, Charcot-Leyden crystals, Curschmann's spiral. ROS generation was increased by 2-fold while SOD was depleted by 31% in biomass users. They also had higher sputum levels of IL-6, -8 and TNF-α. Levels of PM₁₀ and t,t-MA were 2.9- and 5.8-times higher in biomass-using women. PM₁₀ and t,t-MA levels were positively associated with cellular changes in the sputum, markers of airway inflammation, and oxidative stress. Cooking with biomass alters sputum cytology, and increases airway inflammation and oxidative stress that might result in further amplification of the tissue damaging cascade in women chronically exposed to biomass smoke.     

Plantar fasciitis and calcaneal spur formation are associated with abductor digiti minimi atrophy on MRI of the foot

Objective To determine the association of atrophy of the abductor digiti minimi muscle (ADMA), an MRI manifestation of chronic compression of the inferior calcaneal nerve suggesting the clinical diagnosis of Baxter’s neuropathy, with MRI markers of potential etiologies, including calcaneal spur formation, plantar fasciitis, calcaneal edema, Achilles tendinosis and posterior tibial tendon dysfunction (PTTD). Materials and methods Prevalence of calcaneal spur formation, plantar fasciitis, calcaneal edema, Achilles tendinosis and PTTD was assessed retrospectively on 100 MRI studies with ADMA and 100 MRI studies without ADMA. Patients ranged in age from 10–92 years. Pearson chi-square analyses and Fisher’s exact test were used to compare prevalence of the above findings in patients with and without ADMA. Logistic regression was used to determine which variables were significantly associated with ADMA. Results Among patients with ADMA, there was significantly greater age (57.2 years vs 40.8 years, p < 0.001), presence of Achilles tendinosis (22.0% vs 3.0%, P < 0.001), calcaneal edema (15.0% vs 3.0%, P = 0.005), calcaneal spur (48.0% vs 7.0%, P < 0.001), plantar fasciitis (52.5% vs 11.0%, P < 0.001), and PTTD (32.0% vs 11.0%, P < 0.001). After multivariate logistic regression analysis, only age [odds ratio (OR) 1.06, 95% confidence interval (CI) 1.03, 1.09], calcaneal spur (OR 3.60, 95% CI 1.28, 10.17), and plantar fasciitis (OR 3.35, 95% CI 1.31, 8.56) remained significant. Conclusion Advancing age, calcaneal spur, and plantar fasciitis are significantly associated with ADMA. Their high odds ratios support the notion of a possible etiologic role for calcaneal spur and plantar fasciitis in the progression to Baxter’s neuropathy.     

Spinal cord imaging by transesophageal echocardiography: A new modality of monitoring

A 45-year-old patient with known history of Aortic arch aneurysm presented in the emergency ward with features of rupture of the aneurysm into the left lung with compressive signs in the pulmonary parenchyma. Diagnosis was confirmed by magnetic resonance imaging. The patient underwent repair of thoracic aortic aneurysm with left upper lobectomy under general anesthesia and cardio-pulmonary bypass support. Transesophageal echocardiography (TEE) was used for an intraoperative monitoring. While imaging the thoracic aorta with TEE was underway, we accidentally visualized an image that was confirmed to be the spinal cord. So, in this article we discuss how the spinal cord monitoring can be made possible with TEE.     

Comparison of the Prognostic Value of Tumour- and Patient-Related Factors in Patients Undergoing Potentially Curative Resection of Oesophageal Cancer

Background

Evidence is increasing that elevated systemic inflammation is associated with poor survival in patients with oesophageal carcinoma. However, it is not yet established if any specific component of systemic inflammatory response is a better predictor of cancer survival. The aim of the present study was to compare the predictive value of selected markers of systemic inflammation in patients who undergo surgical resection of oesophageal cancer.

Methods

One hundred twelve patients who underwent potentially curative resection for oesophageal carcinoma, including type I and type II tumours of the gastro-oesophageal junction (Siewert and Stein in Dis Esophagus 9:173?C182, 1996), between 1996 and 2008 were included in the study. Patients had laboratory measurement of white cells, neutrophils, lymphocytes, platelet counts, albumin, and C-reactive protein. Glasgow Prognostic Score (mGPS), neutrophil lymphocyte ratio (NLR), platelet lymphocyte ratio (PLR), and metastatic lymph node ratio (LNR) were calculated.

Results

On multivariate analysis, only the LNR (HR 2.87, 95% CI 1.99-4.15, p?p?p?p?=?0.001).

Conclusion

The present study indicates that the mGPS, an acute-phase protein-based prognostic score, better predicts cancer survival compared with the cellular components of systemic inflammation in patients with oesophageal carcinoma.     

Outcome of 234 pregnancies in 140 renal transplant recipients from five middle eastern countries

OBJECTIVE: To study the pregnancy and offspring outcomes in postrenal transplant recipients. METHODS: This is a retrospective case-note review study investigating the outcome of 234 pregnancies in 140 renal transplant recipients from five different Middle Eastern countries. RESULTS: Of the overall pregnancies 74.4% were successful albeit with high prevalences of preterm and Caesarean deliveries (40.8% and 53%, respectively). The mean serum creatinine did not rise significantly during pregnancy in the group as a whole but did so in patients who had serum creatinine of or above 150 micromol/L at the beginning of their pregnancies. The mean birth weight was (2,458 g) with 41.3% of the newborns being of low birth weight (<2,500 g). The prevalences of stillbirths were 7.3% and of spontaneous abortion was 19.3%. Preeclampsia and gestational diabetes were observed in 26.1% and 2% of pregnancies, respectively. CONCLUSIONS: In the presence of good allograft function, the majority of pregnancies in renal transplant recipients have a good outcome but with increased incidence of preeclampsia, reduced gestational age, and low birth weights. Patients with baseline serum creatinine of above 150 micromol/L have an increased risk of allograft dysfunction resulting from the pregnancy.     

Morbidity and Mortality Associated with Gastrectomy for Gastric Cancer

Background

Surgery alone is often inadequate for advanced-stage gastric cancer. Surgical complications may delay adjuvant therapy. Understanding these complications is needed for multidisciplinary planning.

Material and Methods

The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database was queried for patients who underwent gastrectomy for malignancy (ICD-9 code 151.x) from 2005 to 2010. Thirty-day mortality and morbidity were evaluated.

Results

Overall, 2,580 patients underwent gastrectomy for malignancy, divided as total gastrectomy 999 (38.7 %) and partial gastrectomy 1,581 (61.3 %). Overall, serious morbidity occurred in 23.6 %, and the 30-day mortality was 4.1 %. Patients receiving a total gastrectomy were younger and healthier than those receiving a partial gastrectomy for the following measured criteria: age, diabetes, chronic obstructive pulmonary disease and hypertension. Serious morbidity and mortality were significantly higher in the total gastrectomy group than the partial gastrectomy group (29.3 vs. 19.9 %, p < 0.001; and 5.4 vs. 3.4 %, p < 0.015, respectively). The inclusion of additional procedures increased the risk of mortality for the following: splenectomy (odds ratio [OR] 2.8; p < 0.001), pancreatectomy (OR 3.5; p = 0.001), colectomy (OR 3.6; p < 0.001), enterectomy (OR 2.7; p = 0.030), esophagectomy (OR 3.5; p = 0.035). Abdominal lymphadenectomy was not associated with increased morbidity (OR 1.1; p = 0.41); rather, it was associated with decreased mortality (OR 0.468; p = 0.028).

Conclusions

Gastrectomy for cancer as currently practiced carries significant morbidity and mortality. Inclusion of additional major procedures increases these risks. The addition of lymphadenectomy was not associated with increased morbidity or mortality. Strategies are needed to optimize surgical outcomes to ensure delivery of multimodality therapy for advanced-stage disease.
