Women's cardiovascular health - the cardio-oncologic jigsaw.

Improvements in cancer care have led to an exponential increase in cancer survival. This is particularly the case for breast cancer, where 5-year survival in Australia exceeds 90%. Cardiovascular disease (CVD) has emerged as one of the competing causes of morbidity and mortality among cancer survivors, both as a complication of cancer therapies and because the risk factors for cancer are shared with those for CVD. In this review we cover the key aspects of cardiovascular care for women throughout their cancer journey: the need for baseline cardiovascular risk assessment and management, a crucial component of the cardiovascular care; the importance of long-term surveillance for ongoing maintenance of cardiovascular health; and strong evidence for the beneficial effects of physical exercise to improve both cancer and cardiovascular outcomes. There is general disparity in cardiovascular outcomes for women, which is further exacerbated when both CVD and cancer co-exist. Collaboration between oncology and cardiac services, with an emergence of the whole field of cardio-oncology, allows for expedited investigation and treatment for these patients. This collaboration as well as a holistic approach to patient care and key role of patients' general practitioners are essential to ensure long-term health of people living with, during and beyond cancer.

The prevalence and risk factors associated with Iron, vitamin B12 and folate deficiencies in pregnant women: A cross-sectional study in Mbeya, Tanzania.

Maternal nutrition is an important forecaster of infant's and mother's health status in most developing countries. This study aimed at assessing the prevalence and associated risk factors of iron, vitamin B12, and folate deficiencies among pregnant women in Mbeya Tanzania. A cross-sectional study using a cluster randomized sampling was conducted among 420 pregnant women. A structured questionnaire was used to collect socio-demographic and dietary assessment. Body iron store was assessed using serum ferritin measured by immunoturbidimetric assays using a Roche Cobas 400+ biochemistry analyzer. Serum folate was measured by folate microbiological assay, while serum vitamin B12 was measured by immunochemiluminescence assay using a Roche Cobas e411 immunoassay analyzer. Multivariate analysis was performed using Poisson regression. The prevalence of iron, folate, and vitamin B12 deficiencies among pregnant women in Mbeya was 37.8%, 24.0%, and 9.7% respectively. Higher odds of iron deficiency were seen in pregnant women aged 20-24 years older [Adjusted OR = 1.20 (95%CI 1.03, 1.35)], not employed [Adjusted OR = 3.0(95%CI 1.03-1.77)] and, not received iron/folic acid supplementation [Adjusted OR = 1.11 (95%CI 1.003-1.23)]. Pregnant women with highest and middle socio-economic statuses had lower odds of vitamin B12 deficiency [Adjusted OR = 0.83 (95%CI 0.76-0.92)] and [Adjusted OR = 0.89 (95%CI 0.81-0.98)] respectively. Pregnant women who were not employed, not received iron and folic acid supplement during pregnancy and, not consumed edible vegetable cooking oil had significant higher odds of serum folate deficiency [Adjusted OR = 3.0 (95%CI 1.58-5.68)], [Adjusted OR = 1.53 (95%CI 1.21-1.93)] and, [Adjusted OR = 2.77 (1.03-7.44)] respectively. This study confirms that iron, folate and vitamin B12 deficiencies are still a major challenge among pregnant women in Tanzania. We recommend for public health interventions for the provision of vitamin B12 along with iron and folic acid supplementations, especially in pregnant women belong to low socio-economic status and limited knowledge of healthy diet.

A proposal for changing nomenclature from pseudomyxoma peritonei (PMP) to abdomino-peritoneal mucinous carcinoma (APM) based on its long journey and experience from tertiary oncology center in India.

INTRODUCTION: Pseudomyxoma peritonei (PMP) is a generalized term, usually known as "jelly belly" since 1884. Incidence is very low, 1-3 per million people per year. Because of its indolent nature, it is usually diagnosed at an advanced stage, thereby impacting the quality of life. The 5-year survival rate varies from 23 to 86% in world literature. Even 10 years and 20 years of survival have been described. With our experience, we like to propose rename of PMP as abdomino-peritoneal mucinous carcinoma (APM) as we strongly feel the time has come to specify the term and standardize the management strategy. METHODOLOGY: In the premier institute of India and as a tertiary referral center, we experienced the maximum number of advanced cases of APM. From 2012 to 2021, we analyzed all the APM patients based on a prospectively maintained computerized database in the department of surgical oncology and found the reasons for renaming from this traditional one. RESULTS: We included a total of 87 patients who underwent surgical intervention. Thirty-five patients underwent cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC), and 52 patients underwent debulking. In CRS-HIPEC patients, CC-0 was achieved in 28 patients (80%), CC-1 in 4 patients (11.4%), and CC-2 in 3 patients (8.6%). Palliative intent HIPEC was done in 3 patients (8.6%). Clavien-Dindo grade III and IV morbidity was observed in 18.8% of patients with 90 days mortality of 5.7%. CONCLUSION: With our long-term experience and advancement of scientific evidence, we like to propose a new name for PMP as APM. We strongly believe this paper will give a clear picture of this rare disease and standard management outlines.

Learning Curve of Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy - an Analysis of Critical Perioperative and Surgical Outcomes among 155 Peritoneal Surface Malignancy Patients Treated at a Tertiary Care Cancer Centre.

AIMS: Various factors can influence the learning curve of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Initiating CRS and HIPEC programmes in low- and middle-income countries is challenging due to resource constraints and limited availability of expertise. We present our experience of CRS and HIPEC from a learning curve perspective among a cohort 155 peritoneal surface malignancy patients. MATERIALS AND METHODS: Patients undergoing CRS and HIPEC between May 2015 and February 2019 were included in the study. Patients were divided into two consecutive cohorts: the first 73 cases comprised the learning phase, group 1; the subsequent cohort of 82 patients were considered as the implementation phase, group 2. A comparative analysis of clinical and surgical outcome parameters was carried out between the two groups. RESULTS: The clinical spectrum was comparable among group 1/group 2. Most were ovarian (56.8%), colorectal (13.5%) and appendiceal (11.0%) malignancies. Group 2 had a higher number of moderate to high peritoneal cancer index patients (34.1% versus 19.1%), total peritonectomies (48.8% versus 45.2%), multi-visceral resections (colonic 41.5% versus 27.4%, small bowel 25.6% versus 19.1%, diaphragmatic 8.5% versus 6.5% and hepatic resections 8.5% versus 2.7%) and completeness of cytoreduction 0/1 rates (97.6% versus 93.1%). A lower incidence of intraoperative urological injuries (2.6% versus 12.3%) was noticed in group 2 (P = 0.007). Non-significant improvements seen in group 2 included surgery duration (6.0 ± 1.3 h versus 6.4 ± 1.7 h), intensive care unit stay (1.3 ± 1.1 days versus 1.8 ± 1.5 days), overall hospital stay (8.1 ± 0.9 days versus 8.8 ± 1.4 days) and reduction in Clavien-Dindo grade 3-4 complications (25.4% versus 36.9%). CONCLUSIONS: The results of the current study indicate that by implementing standard protocols and mentoring by an experienced team, a learning curve of CRS and HIPEC can be achieved in fewer than 75 cases. The baseline expertise of the treating team can also influence the learning curve.

The Moderating Role of Resilience on Mindfulness, Experiential Avoidance, and Posttraumatic Stress Disorder (PTSD) Symptoms of College Student Veterans: A Cross-Sectional Study.

The purpose of the study was to investigate the moderating effect of resilience on the relationship between mindfulness, experiential avoidance, and posttraumatic stress disorder (PTSD) symptom severity. A cross-sectional study design was used on a sample of 133 college student military veterans. We found a direct effect of mindfulness on PTSD and a significant mediating effect of experiential avoidance on the relationship between mindfulness and PTSD. Resilience also had a significant moderating effect on the relationship between mindfulness and PTSD. This study provides preliminary evidence on the usefulness of integrating resilience development in mindfulness-based interventions for trauma-related disorders.

The use of a binary chelate formulation: Could gadolinium based linear contrast agents be rescued by the addition of zinc selective chelates?

Tissue and bone retention of gadolinium based contrast agents (GBCAs) has become a clinical concern because of the potential short and long term toxic effects of free gadolinium. This is a critical problem for most open-chain agents that more readily transmetallate in vivo, in comparison to macrocyclic compounds. Gadolinium diethylene tri-aminepentaacetic acid bis-glucosamide (Gd-DTPA-BIGA) is an experimental, open-chain contrast agent which has a significantly increased relaxivity coefficient in comparison to other GBCAs. This results in greater signal intensity and improved contrast enhancement. These superior imaging qualities initiated a search for a solution to the transmetallation of this agent. Plasma zinc is a well-known GBCA transmettalation agent. Since the base chelate of Gadodiamide (Gd-DPTA-Bis-Methylamide or Omniscan), DTPA-Bis-Methylamide (DTPA-BMA), readily transmettalates with and binds serum zinc, we hypothesized that a plasma "zinc sink," may significantly reduce transmetallation of linear agents. 5% DTPA-BMA was added to a formulation of Gd-DTPA-BIGA, which was tested against the original formulation of Gd-DTPA-BIGA with 0.2% of the base chelate DTPA-BIGA. These formulations, including gadodiamide, were labeled with 153GdCl3 followed by infusion into cohorts of Sprague Dawley rats which were sacrificed at 1, 30 and 60 days. Internal organs were harvested, along with blood, skin and femur, and analyzed for residual gadolinium. A subset of tissues were also interrogated with ICP-MS. Labeled Gadodiamide and saline where used as controls. Conclusion: The addition of 5% DTPA-BMA, as a zinc binding agent, reduced the transmetallation of the linear agent Gd-DTPA-BIGA, in comparison to its original formulation supplemented with 0.2% BIGA. This result indicates that supplementing linear GBCAs with ancillary chelates may hold promise for reducing, or eliminating the biological archiving of gadolinium in tissues. In addition, this paper provides valuable animal data on the long term retention of gadolinium from linear based contrast agents.

The Effect of Undaria pinnatifida Fucoidan on the Pharmacokinetics of Letrozole and Tamoxifen in Patients With Breast Cancer.

BACKGROUND: Although the use of complementary and alternative medicines is widespread in cancer patients, clinical evidence of their benefits is sparse. Furthermore, while they are often assumed to be safe with regard to concurrent use of anticancer therapies, few studies have been carried out to investigate possible interactions. Fucoidans are a group of sulfated carbohydrates, derived from marine brown algae, which have long been used as dietary supplements due to their reported medicinal properties, including anticancer activity. The aim of this study was to investigate the effect of co-administration of fucoidan, derived from Undaria pinnatifida, on the pharmacokinetics of 2 commonly used hormonal therapies, letrozole and tamoxifen, in patients with breast cancer. METHODS: This was an open label non-crossover study in patients with active malignancy taking letrozole or tamoxifen (n = 10 for each group). Patients took oral fucoidan, given in the form of Maritech extract, for a 3-week period (500 mg twice daily). Trough plasma concentrations of letrozole, tamoxifen, 4-hydroxytamoxifen, and endoxifen were measured using HPLC-CAD (high-performance liquid chromatography charged aerosol detector), at baseline and after concomitant administration with fucoidan. RESULTS: No significant changes in steady-state plasma concentrations of letrozole, tamoxifen, or tamoxifen metabolites were detected after co-administration with fucoidan. In addition, no adverse effects of fucoidan were reported, and toxicity monitoring showed no significant differences in all parameters measured over the study period. CONCLUSIONS: Administration of Undaria pinnatifida fucoidan had no significant effect on the steady-state trough concentrations of letrozole or tamoxifen and was well tolerated. These results suggest that fucoidan in the studied form and dosage could be taken concomitantly with letrozole and tamoxifen without the risk of clinically significant interactions.

Screening of the 'Open Scaffolds' collection from Compounds Australia identifies a new chemical entity with anthelmintic activities against different developmental stages of the barber's pole worm and other parasitic nematodes.

The discovery and development of novel anthelmintic classes is essential to sustain the control of socioeconomically important parasitic worms of humans and animals. With the aim of offering novel, lead-like scaffolds for drug discovery, Compounds Australia released the 'Open Scaffolds' collection containing 33,999 compounds, with extensive information available on the physicochemical properties of these chemicals. In the present study, we screened 14,464 prioritised compounds from the 'Open Scaffolds' collection against the exsheathed third-stage larvae (xL3s) of Haemonchus contortus using recently developed whole-organism screening assays. We identified a hit compound, called SN00797439, which was shown to reproducibly reduce xL3 motility by ≥ 70%; this compound induced a characteristic, "coiled" xL3 phenotype (IC50 = 3.46-5.93 µM), inhibited motility of fourth-stage larvae (L4s; IC50 = 0.31-12.5 µM) and caused considerable cuticular damage to L4s in vitro. When tested on other parasitic nematodes in vitro, SN00797439 was shown to inhibit (IC50 = 3-50 µM) adults of Ancylostoma ceylanicum (hookworm) and first-stage larvae of Trichuris muris (whipworm) and eventually kill (>90%) these stages. Furthermore, this compound completely inhibited the motility of female and male adults of Brugia malayi (50-100 µM) as well as microfilariae of both B. malayi and Dirofilaria immitis (heartworm). Overall, these results show that SN00797439 acts against genetically (evolutionarily) distant parasitic nematodes i.e. H. contortus and A. ceylanicum [strongyloids] vs. B. malayi and D. immitis [filarioids] vs. T. muris [enoplid], and, thus, might offer a novel, lead-like scaffold for the development of a relatively broad-spectrum anthelmintic. Our future work will focus on assessing the activity of SN00797439 against other pathogens that cause neglected tropical diseases, optimising analogs with improved biological activities and characterising their targets.

Fucoidan enhances the therapeutic potential of arsenic trioxide and all-trans retinoic acid in acute promyelocytic leukemia, in vitro and in vivo.

The morbidity and mortality associated with current therapies for acute promyelocytic leukemia (APL) remain a significant clinical concern, despite improvements in patient survival. Consequently, the development of adjuvant therapies that increase efficacy while reducing morbidities is important. Reducing the concentration of the toxic drugs in adjuvant therapy has the potential to reduce unwanted side effects. Therefore, this study aimed to determine the synergistic effects of fucoidan, an anti-tumor agent, with current APL therapies.When the human APL cell line, NB4, was treated in vitro with fucoidan plus ATO and ATRA at therapeutic and sub-therapeutic doses, there was an increase in sub-G0/G1 cells, annexin V/PI-positive-apoptotic cells and DNA fragmentation. This reduction in proliferation and increase in apoptosis was accompanied by enhanced myeloid differentiation as indicated by an increased expression of CD11b. This was not observed with the AML cell line Kasumi-1, suggesting specificity for APL.In vivo treatment of APL-bearing mice with fucoidan+ATRA or fucoidan+ATO delayed tumor growth, induced differentiation and increased tumor volume doubling time. The differentiated APL cells derived from the excised tumor mass exhibited decreased CD44 expression in fucoidan+ATRA treated mice. This could translate to decreased cell migration in APL patients.Our findings provide evidence supporting the use of fucoidan as an adjuvant therapeutic agent in the treatment of APL.

Antifolate Activity of Plant Polyphenols against Mycobacterium tuberculosis.

With the view of exploring phytochemicals as Mycobacterium tuberculosis (Mtb) dihydrofolate reductase inhibitors, known plant polyphenols from various classes were subjected to detailed docking studies. From this in-silico screening, seven polyphenols were selected and tested against Mtb H37 Rv in whole cell assays. The phytochemicals exhibited potential activity ranging from 3 to 183 µm. These molecules were then tested against the pathogenic and human enzymes in a high-throughput microtitre assay. Epigallocatechin gallate showed the best activity and selectivity. The in-silico analysis was in agreement with the assay results. Of these 7 polyphenols, 5 exhibiting minimum inhibitory concentration values of ≤15 µm were tested for synergistic activity with first line drug Ethambutol and second line folate inhibitor para-amino salicylic acid. Epigallocatechin gallate, Magnolol and Bakuchiol exhibited moderate synergistic association by lowering the minimum inhibitory concentration of these drugs. These simple phytochemicals could hence be considered as leads for further studies, or for preparation of semi-synthetic derivatives to be used in combination therapy, for increased anti-tuberculosis activity after validation in-vivo.

Fucoidan and cancer: a multifunctional molecule with anti-tumor potential.

There is a wide variety of cancer types yet, all share some common cellular and molecular behaviors. Most of the chemotherapeutic agents used in cancer treatment are designed to target common deregulated mechanisms within cancer cells. Many healthy tissues are also affected by the cytotoxic effects of these chemical agents. Fucoidan, a natural component of brown seaweed, has anti-cancer activity against various cancer types by targeting key apoptotic molecules. It also has beneficial effects as it can protect against toxicity associated with chemotherapeutic agents and radiation. Thus the synergistic effect of fucoidan with current anti-cancer agents is of considerable interest. This review discusses the mechanisms by which fucoidan retards tumor development, eradicates tumor cells and synergizes with anti-cancer chemotherapeutic agents. Challenges to the development of fucoidan as an anti-cancer agent will also be discussed.

Calcium and vitamin D metabolism in sarcoidosis.

BACKGROUND: Sarcoidosis associated hypercalcemia (SAHC) may be secondary to excessive levels of 1,25-(OH)2 vitamin D3 produced by autonomous 1-alpha-hydroxylase activity within the granulomas.  The frequency, treatment, and consequences of hypercalcemia remain unclear. STUDY DESIGN AND METHODS: Two patient cohorts were studied.  In Cohort 1, the prevalence of hypercalcemia in 1606 sarcoidosis patients seen during a six year period was analyzed along with treatment and outcome. Cohort 2 consisted of  261 sarcoidosis patients with measured 25-(OH) vitamin D3 and 1,25-(OH) vitamin D3 levels. In forty patients, serial levels of 25-(OH) vitamin D3 and 1,25-(OH) vitamin D3 were measured at least three months apart without change in therapy. RESULTS: SAHC was identified in 97 of 1606 (6%) of patients studied and additional nine (0.6%) patients had primary hyperparathyroidism. Post treatment follow up was available in 86 SAHC patients. Hypercalcemia improved in >90% of patients, including eight patients treated solely with vitamin D supplement withdrawal. Renal insufficiency, documented in 41 (42%) of SAHC patients, improved with hypercalcemia treatment.  In 80% of Cohort 2 patients low 25-(OH) vitamin D3 levels were measured with only one patient having a low 1,25(OH)2 vitamin D3 level. Elevated 1,25(OH)2 vitamin D3 levels, which were measured in 11% of patients, were higher for those with a history of hypercalcemia. CONCLUSION: Sarcoidosis associated hypercalcemia, which is often accompanied by renal insufficiency, responds to treatment of sarcoidosis and withdrawal of vitamin D supplementation. Measurement of serum vitamin 1,25(OH)2 vitamin D3 appears to best evaluate vitamin D status in sarcoidosis patients.

Self-rated job performance and absenteeism according to employee engagement, health behaviors, and physical health.

OBJECTIVE: To better understand the combined influence of employee engagement, health behavior, and physical health on job performance and absenteeism. METHODS: Analyses were based on 20,114 employees who completed the Healthways Well-Being Assessment from 2008 to 2010. Employees represented three geographically dispersed companies in the United States. RESULTS: Employee engagement, health behavior, and physical health indices were simultaneously significantly associated with job performance and also with absenteeism. Employee engagement had a greater association with job performance than did the health behavior or physical health indices, whereas the physical health index was more strongly associated with absenteeism. Specific elements of the indices were evaluated for association with self-rated job performance and absenteeism. CONCLUSION: Efforts to improve worker productivity should take a holistic approach encompassing employee health improvement and engagement strategies.

A practical molecular assay to predict survival in resected non-squamous, non-small-cell lung cancer: development and international validation studies.

BACKGROUND: The frequent recurrence of early-stage non-small-cell lung cancer (NSCLC) is generally attributable to metastatic disease undetected at complete resection. Management of such patients depends on prognostic staging to identify the individuals most likely to have occult disease. We aimed to develop and validate a practical, reliable assay that improves risk stratification compared with conventional staging. METHODS: A 14-gene expression assay that uses quantitative PCR, runs on formalin-fixed paraffin-embedded tissue samples, and differentiates patients with heterogeneous statistical prognoses was developed in a cohort of 361 patients with non-squamous NSCLC resected at the University of California, San Francisco. The assay was then independently validated by the Kaiser Permanente Division of Research in a masked cohort of 433 patients with stage I non-squamous NSCLC resected at Kaiser Permanente Northern California hospitals, and on a cohort of 1006 patients with stage I-III non-squamous NSCLC resected in several leading Chinese cancer centres that are part of the China Clinical Trials Consortium (CCTC). FINDINGS: Kaplan-Meier analysis of the Kaiser validation cohort showed 5 year overall survival of 71·4% (95% CI 60·5-80·0) in low-risk, 58·3% (48·9-66·6) in intermediate-risk, and 49·2% (42·2-55·8) in high-risk patients (p(trend)=0·0003). Similar analysis of the CCTC cohort indicated 5 year overall survivals of 74·1% (66·0-80·6) in low-risk, 57·4% (48·3-65·5) in intermediate-risk, and 44·6% (40·2-48·9) in high-risk patients (p(trend)<0·0001). Multivariate analysis in both cohorts indicated that no standard clinical risk factors could account for, or provide, the prognostic information derived from tumour gene expression. The assay improved prognostic accuracy beyond National Comprehensive Cancer Network criteria for stage I high-risk tumours (p<0·0001), and differentiated low-risk, intermediate-risk, and high-risk patients within all disease stages. INTERPRETATION: Our practical, quantitative-PCR-based assay reliably identified patients with early-stage non-squamous NSCLC at high risk for mortality after surgical resection.

Experiences with integrated concepts for the control of Haemonchus contortus in sheep and goats in the United States.

The generally warm, moist environmental conditions in the southern United States (U.S.) are ideal for survival and growth of the egg and larval stages of Haemonchus contortus and other gastrointestinal nematodes (GIN) of sheep and goats. Consequently, infection with GIN is the greatest threat to economic small ruminant production in this region. With anthelmintic resistance now reaching epidemic proportions in small ruminants in the U.S., non-chemical control alternatives are critically needed. The Southern Consortium for Small Ruminant Parasite Control (SCSRPC) was formed in response to this crisis and over the last decade has successfully validated the use of several novel control technologies, including FAMACHA(©) for the implementation of targeted selective treatments (TST), copper oxide wire particles (COWP), nematode-trapping fungi, and grazing or feeding hay of the high-tannin perennial legume sericea lespedeza [Lespedeza cuneata (Dum.-Cours. G. Don)]. Producer attitudes toward GIN control in the U.S. have been shifting away from exclusive dependence upon anthelmintics toward more sustainable, integrated systems of parasite control. Some novel control technologies have been readily adopted by producers in combination with appropriate diagnostic tools, such as FAMACHA(©). Others techniques are still being developed, and will be available for producer use as they are validated. Although new drugs will likely be available to U.S. goat and sheep producers in the future, these will also be subject to development of anthelmintic resistance. Therefore, the adoption and implementation of sustainable GIN control principles will remain important. With emerging markets for grass-fed or organic livestock, there will continue to be a critical need for research and outreach on development and on-farm application of integrated GIN control systems for small ruminants in the U.S. for the foreseeable future.

A comparison of religious orientation and health between Whites and Hispanics.

The study of religious orientation thus far has neglected the influence of race/ethnicity as well as all four religious orientations (intrinsic, extrinsic, pro-religious and nonreligious) in explaining differences in both physical and psychological health. A representative sample of 250 Hispanics and 236 non-Hispanic Whites in Utah was drawn and analysed for differences in health (self-rated health, life satisfaction, exercise) according to race/ethnicity, religious orientation and religious attendance. Responses to the Religious Orientation Scale differed significantly by race/ethnicity, indicating that future studies of religious orientation should take cultural context into account. For both Whites and Hispanics, pro-religious individuals reported the highest life satisfaction scores, which highlight the utility of employing the fourfold religious orientation typology.

The Coronary Health Improvement Project (CHIP) for lowering weight and improving psychosocial health.

This study extends previous research evaluating the association between the CHIP intervention, change in body weight, and change in psychological health. A randomized controlled health intervention study lasting 4 wk. was used with 348 participants from metropolitan Rockford, Illinois; ages ranged from 24 to 81 yr. Participants were assessed at baseline, 6 wk., and 6 mo. The Beck Depression Inventory (BDI) and three selected psychosocial measures from the SF-36 Health Survey were used. Significantly greater decreases in Body Mass Index (BMI) occurred after 6 wk. and 6 mo. follow-up for the intervention group compared with the control group, with greater decreases for participants in the overweight and obese categories. Significantly greater improvements were observed in BDI scores, role-emotional and social functioning, and mental health throughout follow-up for the intervention group. The greater the decrease in BMI through 6 wk., the better the chance of improved BDI score, role-emotional score, social functioning score, and mental health score, with odds ratios of 1.3 to 1.9. Similar results occurred through 6 mo., except the mental health variable became nonsignificant. These results indicate that the CHIP intervention significantly improved psychological health for at least six months afterwards, in part through its influence on lowering BMI.

Hypertension with elevated levels of oxidized low-density lipoprotein and anticardiolipin antibody in the circulation of premenopausal Indian women chronically exposed to biomass smoke during cooking.

UNLABELLED: This study aims to investigate whether indoor air pollution (IAP) from biomass fuel use was associated with hypertension, platelet hyperactivity, and elevated levels of oxidized low-density lipoprotein (oxLDL) and anticardiolipin antibody (aCL). We enrolled 244 biomass fuel-using (median age 34 year) and 236 age-matched control women who cooked with liquefied petroleum gas (LPG). Enzyme-linked immunosorbent assay was used to measure oxLDL in plasma and aCL in serum, flow cytometry for P-selectin expression on platelet and reactive oxygen species (ROS) generation by leukocytes, aggregometry for platelet aggregation, spectrophotometry for superoxide dismutase (SOD) in erythrocytes, and laser photometer for particulate matter <10 and 2.5 µm in diameter (PM(10) and PM(2.5), respectively) in cooking areas. Biomass users had three times more particulate pollution in kitchen, had higher prevalence of hypertension (29.5 vs. 11.0% in control, P < 0.05), elevated oxLDL (170.6 vs. 45.9 U/l; P < 0.001), platelet P-selectin expression (9.1% vs. 2.4%), platelet aggregation (23.2 vs. 15.9 Ohm), raised aCL IgG (28.7% vs. 2.1%), IgM (8.6% of vs. 0.4%), and ROS (44%) but depleted (13%) SOD. After controlling potential confounders, the changes were positively associated with PM(10) and PM(2.5) in indoor air, suggesting a positive association between IAP and increased cardiovascular risk. PRACTICAL IMPLICATIONS: The study showing high risk of developing cardiovascular diseases (CVD) among poor, underprivileged women in their reproductive ages in rural India is important from public health perspectives. It may motivate the government and the regulatory agencies of the country to take a serious note of the indoor air pollution (IAP) from biomass fuel use as it threatens the health of millions of women, children, and the elderly who mostly stay indoor. We hope the findings will strengthen the demand for setting up a standard for indoor air quality in the country in the line of national ambient air quality standard. The findings may also inspire the authorities to take measures for the reduction in IAP by improving housing, kitchen ventilation, and cook stoves. Moreover, the parameters used in this study can be utilized for large, population-based studies to identify women at a higher risk of developing CVD so that medical intervention can be taken at the formative stage of a disease.

The diminishing role of transurethral resection of the prostate.

BACKGROUND: This study provides an update of patterns in transurethral resection of the prostate (TURP) rates in the United States and the extent of TURP-detected prostate cancer incidence rates. METHODS: Analyses are based on data from the National Hospital Discharge Survey, the Surveillance, Epidemiology, and End Results Program, and the U.S. Census Bureau for the years 1996 through 2006. RESULTS: TURP procedure rates were 6, 14, and 18 times greater in men aged 60 to 69, 70 to 79, and >or=80 years compared with men aged 50 to 59, respectively. During 1996-2006, the estimated annual percentage change in TURP rates was -10.5 (95% confidence interval [95% CI] -14.1 to -6.7) for ages 50 to 59, -7.4 (95% CI -9.2 to -5.6) for ages 60 to 69, -6.2 (95% CI -7.6 to -4.8) for ages 70 to 79, and -7.7 (95% CI -9.5 to -5.8) for ages >or=80 years. TURP-detected prostate cancer incidence rates were 2, 7, and 17 times greater in men aged 60 to 69, 70 to 79, and >or=80 years compared with men aged 50 to 59, respectively. The estimated annual percentage change in trend was -17.8 (-20.6, -15.0) for ages 50 to 59, -14.8 (-16.6, -13.0) for ages 60 to 69, -10.8 (-12.0, -9.7) for ages 70 to 79, and -8.2 (-10.0, -6.5) for ages >or=80 years. Trends in prostate cancer incidence rates peaked in 2002 and decreased thereafter. Some of the decreasing trend in rates among older age groups is because of a decrease in TURPs and consequently a decrease in incidental TURP-detected cases. CONCLUSIONS: TURP procedure rates and incidental TURP-detected prostate cancer incidence rates have declined and will likely continue to decline in the future.

Effects of adjuvant and conidial concentration on the efficacy of Beauveria bassiana for the control of the two spotted spider mite, Tetranychus urticae.

Greenhouse experiments were conducted on various crops (cucumber, tomato, eggplant, green bean) to ascertain the effects of Break-thru (polyether-polymethylsiloxane-copolymer, a silicone surfactant) and an oil emulsion, on Beauveria bassiana (Balsamo) Vuillemin (Bb) applications for the control of the two spotted spider mite, Tetranychus urticae Koch. The objectives were to compare a) the efficacy of Bb control when applied in aqueous Break-thru or an oil emulsion; b) the effects of various concentrations of Bb conidia, as affected by each surfactant; and c) the effects of Break-thru on the activity of the fungus. Conidia were suspended either in an aqueous Break-thru or an emulsifiable formulation at different conidial concentrations (1.05 x 10(6), 2.1 x 10(6) and 4.2 x 10(6) conidia ml(-1)) and sprayed onto leaves 2 weeks after artificial pest inoculation. Two sprays were performed, with an interval of one week from one spray to another, and T. urticae population counts (both motile and egg stages) were made on plant leaves 7 days after each spray. Bb conidia in Break-thru((R)) were more efficacious than conidia in emulsifiable formulation. With the highest rate of conidia (4.2 x 10(6) conidia ml(-1)), mortality of adult mites ranged from 60 +/- 4.2 (mean +/- SE) to 85.7 +/- 4.3% in the Break-thru suspension and 39.4 +/- 7 to 61.3 +/- 6% in the oil emulsion. Leaf damage index was also substantially reduced from 70% in the unsprayed control to 40% by the application of Bb conidia at the highest rate with Break-thru. Break-thru can be combined with Bb in the integrated management of T. urticae and Isolate R444 is a promising candidate for the control of the pest.
