Occult myocardial injury is prevalent amongst elderly patients in the hospital-at-home setting. A retrospective analysis of 213 patients. INTERNATIONAL JOURNAL OF CARDIOLOGY. CARDIOVASCULAR RISK AND PREVENTION 2023; 19:200215. [PMID: 37771606 PMCID: PMC10522968 DOI: 10.1016/j.ijcrp.2023.200215] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Revised: 09/10/2023] [Accepted: 09/17/2023] [Indexed: 09/30/2023]
Abstract
Background Hospital-at-Home (HAH) is a valid alternative for in-hospital stay for a wide variety of clinical indications. Occult myocardial injury, associated with acute illness, mainly occurs in patients with a background of non-obstructive coronary disease. The aim of this study was to describe the prevalence of this phenomenon in our HAH population. Methods A retrospective description and analysis of data collected for patients admitted to the Sheba beyond's HAH services during 14 months. Results During a period of 14 months (7/10/21-6/12/22), blood troponin measurements were available for 213 patients (median age 78 years, 52% males) hospitalized mainly for infectious causes. The median HS (highly sensitive) troponin level was 7.7 ng/L (IQR = 13.2 ng/L) (the normal upper limit is 12 ng/L) with 31% of all patients demonstrating an abnormally increased troponin level (68/213). Of all patients, 64% had a background diagnosis of a cardiovascular disease (138/213), of whom, 49% had abnormal HS troponin levels (68/138). No patient suffered from acute cardiac function deterioration and no patient died during their hospital-at-home stay. Conclusion The prevalence of occult myocardial injury amongst elderly patients admitted to hospital-at-home stay for diagnoses other than myocardial infarction is relatively high but it is not associated with worse short-term clinical outcomes.

Abstract
BackgroundEarly arthritis is an inflammatory disease with the potential to progress to persistent arthritis, such as established Rheumatoid Arthritis (RA) or other articular disease, to resolve spontaneously or remain undifferentiated for indefinite periods of time.ObjectivesTo identify predictors of persistent RA after 12 months follow up in the Argentinean early arthritis clinic (CONAART).MethodsWe conducted an observational, prospective longitudinal study, including patients with early arthritis (at least 1 swollen joint with <2 years of evolution) who had at least one year of follow-up.Sociodemographic and clinical data and characteristics of the disease were recorded at baseline, at 3, 6 and 12 months. After 1 year of follow-up, each patient was classified according to diagnosis: self-limited arthritis, persistent non-erosive arthritis, or persistent erosive arthritis.The association between the different predictors of diagnosis at 12 months was evaluated using multiple logistic regression, adjusted by potential confounders. Rheumatoid Factor (RF) and Anti Citrullinated Peptide Antibodies (ACPA) were included in separate models in order to avoid multicollinearity. A value of p<0.05 was considered significant.ResultsWe included 839 patients, 83% females, mean age of 57±14 years and mean disease duration of 8.2±6.2 months; 67.5% were rheumatoid factor positive and 59% ACPA positive. Disease characteristics at baseline were DAS28 5.1±1.4, swollen joints 6±5, erythrocyte sedimentation rate (ESR) 34±25 mm/h, C Reactive Protein (CRP) 4±6 and Health Assessment Questionnaire-Argentinean (HAQ-A) 1.2±0.8.After 12 months follow up, 11% of the patients were diagnosed as self-limited disease, whereas 89% were diagnosed as persistent disease. For the persistent disease, 34% presented radiograph erosions and therefore were catalogued as persistent erosive disease.The seropositivity for both, RF and ACPA, together with baseline DAS28, were the variables independently associated with the development of persistent disease at 12 months. [Model 1a: RF OR 2.33 (95% CI 1.44, 3.78) and DAS28 1.27 (1.06, 1.52); Model 2a: ACPA 2.61 (1.38, 4.93) and DAS28 1.59 (1.24, 2.04)].

Abstract
BackgroundFor children with polyarticular juvenile idiopathic arthritis (pJIA) and inadequate response or intolerance to initial treatment with MTX, treatment options include abatacept.1 Abatacept, a selective T-cell co-stimulation modulator, has a distinct mechanism of action from other current treatments for rheumatic diseases,2 and factors predicting clinical response can help determine optimal treatment strategy. Two phase 3 studies demonstrated the efficacy and safety of IV and SC abatacept in patients with pJIA and an inadequate response to other DMARDs.2,3ObjectivesTo determine baseline and post-baseline factors that may predict a clinical response in children and adolescents with pJIA treated with abatacept for 2 years.MethodsBaseline demographic and disease characteristics and post-baseline factors (50% and 70% improvement in ACR criteria [ACR50, ACR70] at days 57 and 85) were analyzed using data from 2 phase 3 studies of abatacept in patients with JIA aged 2–17 years (SC administration) and 6–17 years (IV administration). Efficacy endpoints were Juvenile Arthritis Disease Activity Score in 10 joints based on CRP (JADAS10-CRP) inactive disease (ID; score of ≤ 2.7),4 and remission, defined as 6 consecutive months of post-baseline JADAS10-CRP ID. Data were analyzed over the entire 2-year study period. The earliest time point at which patients achieved these outcomes was reported. The aforementioned study factors were subjected to a time-to-event analysis, including Cox proportional hazards univariate regression analysis and Cox proportional hazards multivariate regression analysis using stepwise regression; results of the multivariate analysis are reported. Kaplan–Meier analysis was used to estimate time to achieve clinical response. Receiver operating characteristic curves were used to determine threshold values for continuous variables.ResultsOverall, 347 patients were included in the analysis (SC, n = 219; IV, n = 128; 73.8% female; mean [SD] age, 11.3 [4.0] years). Following abatacept treatment, both time to JADAS10-CRP ID and time to JADAS10-CRP remission were predicted (nominal P ≤ 0.05) by age (≤ 11 years: hazard ratio [HR], 1.52 [95% CI, 1.14–2.02] and ≤ 10 years: HR, 1.73 [95% CI, 1.20–2.48], respectively), high-sensitivity CRP (hsCRP; ≤ 0.6 mg/dL: HR, 1.67 [95% CI, 1.22–2.28] and ≤ 0.21 mg/dL: HR, 1.67 [95% CI, 1.15–2.42], respectively), Parent/Patient Global Assessment of well-being (≤ 35.86: HR, 1.88 [95% CI, 1.41–2.51] and ≤ 43.16: HR, 2.05 [95% CI, 1.35–3.10], respectively), and Childhood HAQ-DI (CHAQ-DI; ≤ 1.63: HR, 2.23 [95% CI, 1.47–3.39] and ≤ 0.75: HR, 1.84 [95% CI, 1.24–2.73], respectively) (remission data shown in Figure 1). Disease duration ≤ 2 years from baseline (HR, 1.66 [95% CI, 1.25–2.21]) and SC route of administration (HR, 2.05 [95% CI, 1.45–2.91]) also predicted ID. Among the post-baseline factors, ACR50 at days 57 and 85 predicted both ID (HR, 1.57 [95% CI, 1.04–2.36] and HR, 1.88 [95% CI, 1.41–2.51], respectively) and remission (HR, 1.96 [95% CI, 1.11–3.45] and HR, 3.05 [95% CI, 1.47–6.34], respectively); ACR70 at day 57 also predicted ID (data not shown). Patients with predictive factors for age, hsCRP, Parent/Patient Global Assessment of well-being, and CHAQ-DI, and with lower disease activity achieved ID and/or remission earlier than patients with high disease activity.ConclusionWe identified baseline and post-baseline factors that predicted JADAS10-CRP ID and remission in patients with pJIA treated with abatacept for 2 years. Screening of abatacept-treated patients with pJIA for such factors may help predict earlier achievement of ID and/or remission.References[1]Ringold S, et al.

Abstract
Abstract
Background
Autoimmune systemic inflammatory diseases are associated with an increased risk of cardiovascular disease, particularly myocardial infarction (MI). However, there are limited data on the prevalence and effects of inflammatory disease among U.S. adults who experience an MI at a young age.
Purpose
We sought to determine the prevalence and prognostic value of inflammatory disease in U.S. adults who experience an MI at a young age.
Methods
The YOUNG-MI registry is a retrospective cohort study of consecutive patients who experienced a Type 1 MI at or below the age of 50 years from 2000 to 2016 at two large medical centers. A diagnosis of rheumatoid arthritis (RA), psoriasis (PsO), systemic lupus erythematosus (SLE), or inflammatory arthritis was determined through physician review of electronic medical records (EMR). Demographic information, presence of cardiovascular (CV) risk-factors, medical procedures, and medications upon discharge were also ascertained from the EMR. Incidence of death was determined using a combination of EMR and national databases. Cox proportional hazard modeling was performed on a sub-sample following Mahalanobis Distance matching on age, sex, and CV risk factors.
Results
The cohort consisted of 2097 individuals (median age 45 years, 19% female, 53% ST-elevation MI). Among these, 53 (2.5%) individuals possessed a diagnosis of systemic inflammatory disease at or before their index MI (23% SLE, 9% RA, 64% PsO, 4% inflammatory arthritis). When compared to the remainder of the cohort, patients with a diagnosis of systemic inflammatory disease were more likely to be female (36% vs 19%, p=0.004) and be diagnosed with hypertension (62% vs 46%, p=0.025). There was, however, no significant difference in the prevalence of other CV risk factors – diabetes, smoking, dyslipidemia – or a family history of premature coronary artery disease. Despite these similarities, patients with inflammatory disease were less likely to be prescribed aspirin (88% vs 95%, p=0.049) or a statin (76% vs 89%, p=0.008) upon discharge. Over a median follow-up of 11.2 years, patients with inflammatory disease experienced an increased risk of all-cause mortality when compared with the full-cohort (Figure). Compared to the matched sample (n=138), patients with systemic inflammatory disease exhibited an increased risk of all-cause mortality (HR=2.68, CI [1.18 to 6.07], p=0.018), which remained significant after multivariable adjustment for length of stay and GFR (HR=2.38, CI [1.02 to 5.54], p=0.045).
Conclusions
Among individuals who experienced an MI at a young age, approximately 2.5% had evidence of a systemic inflammatory disease at or before their MI. When compared with a population of individuals with similar cardiovascular risk profiles, those with inflammatory disease had higher rates of all-cause mortality. Our findings suggest that the presence of a systemic inflammatory disorder is independently associated with worse long-term outcomes.

Abstract
Abstract
Background
Pulmonary artery (PA) injury is a rarely reported complication following percutaneous left atrial appendage closure (LAAC). This study aims to systematically review all reported cases of PA injury associated with LAAC.
Methods
PubMed/Medline, SCOPUS, EMBASE, Google Scholar and the MAUDE databases were searched to find studies reporting PA injury during or after LAAC with the Amplatzer Amulet (AA), Amplatzer Cardiac Plug (ACP) or Watchman device through October 2019. Categorical data were reported in terms of numbers and/or percentages (%).
Results
We found 13 cases (mean age 71.4 yrs) with reported PA injury associated with LAAC. Of these, 9 were case reports, 3 were reported in observational studies, and 1 was in the MAUDE database. Most cases (n=8) were reported in Europe followed by Australia (n=2) and Asia (n=2). The indication for device implantation in all patients was a high bleeding risk with anticoagulation for atrial fibrillation. Five cases were reported with the ACP (1/5 patients died), 5 with AA (2/5 patients died), and 3 with the Watchman (1/2 patients died). Acute and late presentations following implantation were reported for all three devices. 69.2% of cases (9/13) occurred acutely (during or within 24 hours of intervention). Of these, 3/9 occurred during device implantation. 2/4 of the delayed cases occurred >2 weeks following implantation. The mortality rate for acute and delayed cases was 22% (2/9 patients) and 50% (2/4 patients), respectively. A majority of the cases were attributable to barb/strut/hook injury of the PA. PA injury was associated with a mortality rate of approximately 31%. All surviving patients were managed with surgical intervention.
Conclusion
PA injury is an infrequently reported complication following LAAC and is associated with high mortality. Cases can present acutely (intra-procedurally or within 24 hours) or delayed (>24 hours post-implantation). A majority of cases are due to direct injury of the PA by the struts/hooks/barbs of the device. Practitioners should be cognizant of this life-threatening complication, which requires a high index of suspicion for diagnosis and can occur weeks after device implantation.

Abstract
Polymer gel dosimeters are instrumental for clinical and research applications in radiotherapy. These dosimeters possess the unique ability to record dose distribution in three dimensions. A Polymer gel dosimeter is composed of organic molecules in a gel matrix, which upon irradiation polymerize to form a conjugated polymer with optical absorbance proportional to the irradiated dose. Other required characteristics of a radiotherapy clinical dosimeter are soft-tissue equivalency, linear dose-response in a range of clinical treatments, and long term stability for the duration of the analysis. The dosimeter presented in this paper is based on diacetylene bearing fatty acid aggregates embedded in a soft-tissue equivalent gel matrix, Phytagel™, which upon irradiation polymerize to form a blue phase polydiacetylene with a strong optical absorption. Initial characterization showed that PDA-gel irradiated with 160 kV x-ray responded linearly to the irradiated dose, and the calculated diffusion coefficient is [Formula: see text] what is very low. It was also found that the percentage depth dose (PDD) curve of the PDA-gel in a 4 × 4 cm2 field, irradiated with 6 MV x-rays, was with good agreement with the literature. PDA-gel has the potential to detect absorbed dose in a range of clinical radiological irradiation regimes.

Abstract
INTRODUCTION 3D printing is being used more extensively in modern biomedicine. One of the problems is selecting a proper crosslinking method of bioprinted material. Amongst currently used techniques we can distinguish: physical crosslinking (e.g. Ca2+ and Sr2+) and chemical crosslinking-the UV light crosslinking causing the biggest discussion. UV radiation is selectively absorbed by DNA, mainly in the UV-B region but also (to some extent) in UV-A and UV-C regions. DNA excitement results in typical photoproducts. The amount of strand breaks may vary depending on the period of exposition, it can also differ when cells undergo incubation after radiation. AIM The aim of this study was to show whether and how the time of irradiation with 405 nm and 365 nm wavelengths affect DNA damage in cell lines and micro-organs (pancreatic islets). MATERIALS AND METHODS The degree of DNA damage caused by different wavelengths of radiation (405 nm and 365 nm) was evaluated by a comet assay. The test was performed on fibroblasts, alpha cells, beta cells and porcine pancreatic islets after 24 hours incubation period. Samples without radiation treatment were selected as a control group. Results analysis consisted of determining the percent of cells with damaged DNA and the tail intensity evaluation. RESULTS The degree of DNA damage in pancreatic islets after exposure to 405 nm wavelength oscillated between 2% and 6% depending on the tested time period (10 - 300 seconds). However, treating islets using 365 nm wavelength resulted in damage up to 50%. This clearly shows significantly less damage when using 405 nm wavelength. Similar results were obtained for the tested cell lines. CONCLUSIONS Crosslinking with 405 nm is better for pancreatic islets than crosslinking with 365 nm UV light.

An overview of heat stress relief with global warming in perspective. INTERNATIONAL JOURNAL OF BIOMETEOROLOGY 2019; 63:493-498.

Abstract
Global warming seems more probable, whether as gradual warming or increased frequency of warmer episodes. The productivity of cattle in temperate countries will decline unless counteracting steps are adopted. The probability of pre-emptive breeding for maintaining temperate breed performance coupled with heat stress tolerance is too low to be adopted for counteracting warming. The expected warming will mostly involve temperature increases. These will indirectly affect radiant heat gain in animals owing to reduced radiant heat dissipation from the body by convective heat loss, which results in an increased sensitivity to incoming radiant heat at higher air temperatures. These necessitate an emphasis on increasing convective heat loss by structure design and forced air flow by fans. Convective heat loss diminishes with increasing air temperatures. Evaporative heat loss remains the alternative. Evaporative cooling of the ambient requires partial enclosing of the space surrounding the animals and is limited by the humidity in ambient air. An alternative was developed of coupling forced ventilation with wetting of animal surface. The exchange of ambient air flowing on animal surface makes the evaporation practically independent of air humidity and the loss of heat from animal surface practically independent of the surface to air temperature gradient. The coupling of forced ventilation with wetting combination may be attained in various parts of the dairy farm, the holding area of the milking parlour, the feeding trip and the resting area. Each of these requires differing structural and technological adaptations. Climate and farming systems vary between locations which require specific solutions.

Abstract
BACKGROUND Total pancreatectomy and autologous transplantation of pancreatic islets is a treatment option for patients with severe pain due to chronic pancreatitis. In the standard procedure, pancreatic islets are isolated and subsequently administered into the portal vein. In the case of patients with a history of thrombosis or at risk of thrombosis, this route of administration is not viable. Animal studies conducted in our department led to the development of a technique of endoscopic islets transplantation into the gastric submucosa. In 2013 and 2014, the first human autologous transplant procedures were performed. The objective of this study was to present the results of a 3-year follow-up of these patients. METHODS Two pancreatectomies were performed in our department, the first in 2013 and another in 2014, along with subsequent autologous transplantation of pancreatic islets into the gastric submucosa. RESULTS Both patients had been diagnosed previously with diabetes, and both had endogenous islet activity detected. Peptide C concentration after pancreatectomy and before pancreatic cell transplantation was 0.1 ng/mL. After the transplantation, peptide C concentrations for the 2 patients were 0.8 and 0.5 ng/mL on day 7, 1.2 and 0.6 ng/mL on day 30, 1.3 and 0.8 ng/mL on day 180, 1.1 and 0.7 ng/mL on day 360, and 3.0 and 0.6 ng/mL at 3 years, respectively, after transplantation. The pain symptoms resolved in both cases. CONCLUSION Pancreatic islets may survive in the gastric wall. Endoscopic submucosal transplantation may present an alternative for the management of patients who cannot undergo a classic transplantation procedure.

Abstract
BACKGROUND Islets transplantation is an established treatment method for patients suffering from brittle diabetes with hypoglycemia unawareness. The standard implantation technique is through the portal vein into the liver. In case of liver diseases or portal hypertension, finding an extra-hepatic site is recommended. There have been attempts to perform islets transplantations into muscles and into the gastric submucosa. OBJECTIVE The aim of this study is to show a 4-year follow-up of allotransplantation into gastric submucosa in a case of portal hypertension observed during the procedure of islets infusion. PATIENTS AND METHODS A 36-year-old woman with complicated diabetes for over 30 years was selected to receive simultaneous islets and kidney transplantation. The patient underwent an unsuccessful simultaneous pancreas and kidney transplantation 2 years earlier in another transplantation center. The patient's daily insulin requirement was 60 IU, which corresponded to 1.15 IU/kg of body weight. The HbA1c level was 7.4%. C-peptide levels, both fasting and stimulated, were 0.01 ng/mL. On December 7, 2013, the patient received transplanted kidney and islets procured from the same donor. Only 124,000 islets equivalents (IEQ) were isolated (2400 IEQ/kg body weight). Islets were suspended in 300 mL of Ringer's solution along with albumin, antibiotics, and heparin. After infusing 100 mL of the islets suspension into the portal vein, pressure in portal vein increased from 5 mm Hg to 23 mm Hg. Despite stopping the infusion, pressure did not drop after 30 minutes. The decision was made to transplant the reminder of the islets (200 mL) into the gastric wall. RESULTS No complications were observed after the procedure. Serum creatinine level was 1.6 mg/dL on day 10 and 1.5 mg/dL 4 years after the transplantation. Fasting C-peptide levels were 1.7, 0.65, 0.55, 0.69, 0.68, and 0.2 ng/mL at 1, 3, 6, 12, 18, and 36 months after the transplantation, respectively. HbA1c levels were 5.2, 6.4, 4.7, 5.2, and 5.9% at 3, 6, 12, 18, and 36 months, respectively. The patient's insulin requirement dropped to 15 U/day immediately after transplantation and equaled 20 and 27 U/day at 18 and 48 months after the simultaneous islet and kidney transplantation, respectively. CONCLUSION Allotransplantation of islets into the gastric wall may be a safe alternative in cases of contraindications for transplantation into the portal vein.

Abstract
AIM A major problem for the transplant society is a shortage of organs for transplantation compared with the number of patients on the waiting list. This study aimed to assess the results of the transplantation of kidneys procured from older donors. PATIENTS AND METHODS A total of 27 kidneys procured from donors age 70 years or older were transplanted between January 1, 2010, and April 25, 2015. These represented only 4.1% of the 657 kidneys transplanted from deceased donors during this period at the same center. RESULTS Delayed graft function (DGF) in the recipients of kidneys procured from donors age 70 or older occurred in 46.1% of patients, whereas the recipients of kidneys from younger donors showed DGF at a frequency of 32.7% (P = NS). The annual and 3-year survival rates of kidneys in the study group were 85% and 80%, respectively, and in the control group were 92.5% and 88.6%, respectively (P = NS). According to the Polish National Organ Procurement Organization (Poltransplant), the annual survival rate of a transplanted kidney in Poland stands at 89%, whereas the 3-year survival rate is 82%. We detected no significant posttransplantation differences in the serum creatinine concentration and in the estimated glomerular filtration rate between the study and control groups. The donor age and donor creatinine were the variables independently associated with DGF. CONCLUSIONS The results of transplantation of kidneys from elderly donors were comparable to those of transplantation from younger donors. Kidneys harvested from elderly donors should be used for a transplant after a preliminary assessment.

Abstract
OBJECTIVES To determine the interest of saline contrast sonohysterography in the evaluation of number, size and shape of cesarean scar defects in comparison with 3D-transvaginal ultrasound examination. METHODS Patients who had surgical reparation of cesarean scar defect by operative hysteroscopy were included in this retrospective study. Before surgery, they all had 3D-transvaginal ultrasound examination and saline contrast sonohysterography to establish the diagnosis. Then those two exams were compared to determine which one is better for cesarean scar defect evaluation, in terms of diagnosis and severity. RESULTS Fourteen patients were enrolled, they underwent transvaginal ultrasound and saline contrast sonohysterography before the surgery. 3D-transvaginal ultrasound examination made the diagnosis in 50% of patients with cesarean scar defect, whereas saline contrast sonohysterography enabled to detect 86% of defects, in comparison with hysteroscopy (100%). In 29% of patients, the size and depth of the cesarean scar defect was more important with saline contrast sonohysterography and hysteroscopy than expected by 3D-transvaginal ultrasound examination. After surgical repair, symptoms improvement was found in 82% of case (pain or abnormal uterine bleeding), and fertility was restored in 67%. CONCLUSION Saline contrast sonohysterography is better to characterize cesarean scar defects than 3D-transvaginal ultrasound, with a higher sensibility. Moreover, it evaluates more precisely the size and shape of the defect, thus severity.

A comparison of THI indices leads to a sensible heat-based heat stress index for shaded cattle that aligns temperature and humidity stress. INTERNATIONAL JOURNAL OF BIOMETEOROLOGY 2016; 60:1453-1462. [PMID: 26817655 DOI: 10.1007/s00484-016-1136-9] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/25/2015] [Revised: 11/25/2015] [Accepted: 01/12/2016] [Indexed: 06/05/2023]
Abstract
The combined temperature-humidity heat stress is estimated in farm animals by indices derived of an index based on human thermal comfort sensation. The latter index consists of temperature and humidity measures that sum to form the temperature-humidity index (THI). The hitherto unknown relative contribution of temperature and humidity to the THI was examined. A temperature-humidity data set (temperature 20-42 °C and relative humidity 10-70 %) was used to assess by regression procedures the relative weights of temperature and humidity in the variance of THI values produced by six commonly used heat stress indices. The temperature (Ta) effect was predominant (0.82-0.95 of variance) and humidity accounted for only 0.05 to 0.12 of THI variance, half of the variance encountered in animal responses to variable humidity heat stress. Significant difference in THI values was found between indices in the relative weights of temperature and humidity. As in THI indices, temperature and humidity are expressed in different physical units, their sum has no physical attributes, and empirical evaluations assess THI relation to animal responses. A sensible heat THI was created, in which at higher temperatures humidity reaches 0.25 of sensible heat, similarly to evaporative heat loss span in heat stressed animals. It relates to ambient temperature-humidity similarly to present THI; its values are similar to other THI but greater at higher humidity. In warm conditions, mean animal responses are similar in both indices. The higher sensitivity to humidity makes this index preferable for warm-humid conditions.

Abstract
Globally, over 800 000 people died by suicide in 2012 and there are indications that for each adult who died of suicide there were likely to be many more attempting suicide. There are many millions of people every year who are affected by suicide and suicide attempts, taking into consideration the family members, friends, work colleagues and communities, who are bereaved by suicide. In the WHO Mental Health Action Plan 2013-2020, Member States committed themselves to work towards the global target of reducing the suicide rate in countries by 10% by 2020. Hence, the first-ever WHO report on suicide prevention, Preventing suicide: a global imperative, published in September 2014, is a timely call to take action using effective evidence-based interventions. Their relevance for low- and middle-income countries is discussed in this paper, highlighting restricting access to means, responsible media reporting, introducing mental health and alcohol policies, early identification and treatment, training of health workers, and follow-up care and community support following a suicide attempt.

Inter-animal radiation as potential heat stressor in lying animals. INTERNATIONAL JOURNAL OF BIOMETEOROLOGY 2014; 58:1683-1691.

Abstract
A model for predicting inter-animal radiant heat exchange in shaded animals is presented, with emphasis on mature cattle. When a cow's surface temperature is 35 °C, as is common in warmer climates, it loses ∼510 Watt m(-2) as radiant heat. Net radiant heat balance depends on radiation coming from bodies in the vicinity. In the 30 °C radiant temperature shaded environment typical of warm climates, net radiant loss from a lactating cow is ∼60 Watt m(-2), i.e., 30 % of its ∼173 Watt m(-2) heat production. Cows rest for 8-14 h day(-1). The heat exchange of a lying cow differs from that of a standing one: the body center is low and 20-30 % of its surface contacts a surface of relatively low heat conductance. Lying reduces the impact of the surrounding shaded area on heat exchange but increases that of heat radiating from neighboring cows. When a cow rests adjacent to other cows, with 1.25 m between body centers when in stalls, it occupies about 140° of the horizontal plane of view. Heat emitted from the animal's surface reduces the net radiant heat loss of a resting cow by ∼30 Watt m(-2). In contrast, the presence of cows at 5 and 10 m distance, e.g., cows resting on straw in loose yard housing, reduces the net radiant heat loss of the resting cow by 9 and 5 Watt m(-2), respectively. Radiant heat input increases with animal density, which is beneficial in cooler climates, but acts as a stressor in warm climates.

Abstract
Reducing thermal radiation on shaded animals reduces heat stress independently of other means of stress relief. Radiant heat exchange was estimated as a function of climate, shade structure, and animal density. Body surface portion exposed to radiant sources in shaded environments was determined by geometrical relations to determine angles of view of radiation sources (roof underside, sky, sun-exposed ground, shaded ground) on the animal's surface. The relative representation of environment radiation sources on the body surface was determined. Animal thermal radiation balance was derived from radiant heat gained from radiation sources (including surrounding animals) and that lost from the animal surface. The animal environment was assumed to have different shade dimensions and temperatures. These were summed to the radiant heat balance of the cow. The data formed served to estimate the effect of changes in intensity of radiation sources, roof and shaded surface dimensions, and animal density on radiant heat balance (Rbal) of cattle. Roof height effect was expressed by effect of roof temperature on Rbal. Roof underside temperature (35 to 75°C) effect on Rbal was reduced by roof height. If roof height were 4m, an increase in its underside temperature from 35 to 75°C would increase mean Rbal from -63 to -2 W·m⁻², whereas if roof height were 10 m, Rbal would only increase from -99 to -88 W·m⁻². A hot ground temperature increase from 35 to 65°C reduced mean Rbal heat loss from -45 to 3 W·m⁻². Increasing the surface of the shaded area had only a minor effect on Rbal and on the effect of hot ground on Rbal. Increasing shade roof height reduced the effect of roof temperature on Rbal to minor levels when height was > 8m. Increasing the roof height from 4 to 10 m decreased Rbal from -32 to -94 W·m⁻². Increasing indirect radiation from 100 to 500 W·m⁻² was associated with an increase in Rbal from -135 to +23 W·m⁻². Their combined effects were lower Rbal with increasing roof height and a reduction in rate of decrease with increasing level of indirect radiation. Roof height as an Rbal attenuator declined with increasing indirect radiation level. The latter factor might be reduced by lowering roof surface radiation absorption and through roof heat transfer, as well as by use of shade structure elements to reduce indirect radiation in the shaded area. Radiant heat from the cow body surface may be reduced by lower cow density. Radiant heat attenuation may thus further elevate animal productivity in warm climates, with no associated operation costs.

Abstract
Amyloidosis results from proteins being deposited as insoluble β-pleated sheets and disrupting organ function. Each precursor protein induces a separate spectrum of organ involvement, and different disease manifestations within the lung. Although autopsy findings often demonstrate amyloid deposits in various compartments of the lung, few are manifested pathologically. Amyloid lung nodules with positron emission tomography (PET) uptake are rare. We describe a rare case where PET uptake was detected in a pulmonary amyloid nodule. To our knowledge there are six previously reported cases in the English literature. This review also focuses on amyloid derived from immunoglobulin light-chain protein (AL disease), which most frequently involves the lung in both systemic and localized forms of the disease. Manifestations of AL-related lung disease range from nodules identified on incidental chest films to diffuse alveolar and septal deposition mimicking malignancy and or diffuse alveolar damage.

Abstract
Sea urchin skeletal elements are composed of single crystals of calcite. Unlike their synthetic counterparts, these crystals do not have well-developed cleavage and are consequently much more resistant to fracture. This phenomenon is due in part to the presence of acidic glycoproteins occluded within the crystals. By means of x-ray diffraction with synchrotron radiation, it is shown that the presence of the protein in synthetic calcite only slightly decreases the coherence length but significantly increases the angular spread of perfect domains of the crystals. In biogenic calcite, the coherence length is 1/3 to 1/4 as much as that in synthetic calcite and the angular spread is 20 to 50 times as wide. It is proposed that the presence of macromolecules concentrated at mosaic boundaries that are oblique to deavage planes is responsible for the change in fracture properties. These results may be important in the material sciences, because of the unusual nature of this material, namely, a composite based on the controlled intercalation of macromolecules inside single-crystal lattices.

Abstract
The objective was to determine the prevalence of the metabolic syndrome (MS) in patients with systemic lupus erythematosus (SLE) in Argentina, to assess the factors associated to it, and to compare the results with a control group with non-inflammatory disorders. The study included 147 patients with SLE and 119 controls. MS was defined according to criteria by the American Heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI) Scientific Statement. Demographic characteristics, Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and Systemic Lupus International Collaborating Clinics/ACR Damage Index (SDI) were assessed as well as administration, maximum dose and cumulative dose of prednisone and hydroxychloroquine (HCQ). MS prevalence was 28.6% (CI 95%: 21.4-36.6) in patients with SLE and 16% in controls (P = 0.0019). Patients with SLE presented higher arterial hypertension frequency compared with controls (43 vs 25%, P = 0.007). When comparing lupus patients with MS (n = 41) and without MS (n = 106), no significant differences were observed regarding duration of the disease, SLEDAI or cumulative prednisone dose. Cumulative damage was associated independently with MS (OR 1.98; P = 0.021), whereas HCQ use was found to be protective (OR 0.13; P = 0.015). Patients with lupus presented higher MS prevalence than controls with non-inflammatory disorders, and occurrence of arterial hypertension was also higher. MS was associated with cumulative damage; the use of HCQ showed to be protective against presence of MS.

Abstract
7589 Background: Thymic malignancies are rare tumors. Chemotherapy is used for advanced disease. There is no established role of second-line therapy in patients with refractory or recurrent disease. Belinostat is an HDAC inhibitor with activity in cutaneous and peripheral T cell lymphoma and is being investigated in several solid tumors. One prolonged minor response (31 m) was seen in a phase I study of this agent in a patient with thymoma. Methods: Patients with recurrent thymoma or thymic carcinoma, progressing after platinum-based chemotherapy were eligible. They were also required to have measurable disease, PS 0–2 and normal organ functions. Belinostat was given iv at 1.0 g/m2 on days 1–5 of a 21-day cycle until disease progression or intolerable side effects. Correlative markers of activity in blood and tumor were performed. Results: From December 07 to December 08, 22 patients have been accrued from 2 institutions; 12 patients were males, median age 52 (23–72), 14 thymomas and 8 thymic carcinomas, mean number of prior regimens 3.5 (1–10), 16 prior tumor resection and 3 myasthenia gravis. A median of 4 cycles have been given (1–15+). Treatment was well tolerated, with nausea being the most common side effect and well controlled with prophylactic antiemetics. 21 patients are evaluable for response: 2 had a partial response (9+, 9+ m), 13 stable disease (3–11+ m) and 6 progression. No responses were seen in 8 evaluable patients with thymic carcinomas. Acetylated lysine and tubulin were analyzed in lymphocytes and monocytes by multiparameter flow cytometry. An increase of protein acetylation (2–10 fold) over baseline was observed at 1 hour post-infusion on day 3 of the first cycle in all patients analyzed. Other correlative markers are being investigated. Conclusions: The thymoma cohort has been expanded to the second stage of the study. Belinostat has activity in patients with recurrent or refractory thymoma. No significant financial relationships to disclose.
