The paper presents some preliminary results of the monitoring of Tulipa biebersteiniana Schult. et Schult. fil. plants (category of rare and endangered plant species). By summarizing the available sources of science literature we have compiled a general description of morphological and bio-ecological species characteristics. The results of the field study fulfilled in 2012-2015 in two population groups of the Krasnosamarsky forestry (Samara region) were used to determine morphometric parameters of Tulipa biebersteiniana plants. The data also helped us to assess the variability level and to make a comparison with plant quantitative traits given in the literature. It was found that the shoot length of Tulipa biebersteiniana plants varied in the range of 23 50 cm, the maximum average length of 40 cm are presented in plants of population group number two. The distribution of shoot length among individuals of the second population group is more stable, changes depending on the year of vegetation are poorly expressed. The lengths of shoots inside the range specified for the various parts of the area in the literature with a significant proportion of high plants in the population is studied. This may be a sign of good growth conditions for Fritillaria ruthenica that gives an opportunity to the plant conservation in natural communities in the absence of limiting anthropogenic factors.

The article presents some preliminary results of the monitoring of Fritillaria ruthenica Wikstr. plants (category of rare and endangered plant species, included in the Red Books of Russia and Samara Region). By summarizing the available sources of science literature we have compiled a general description of morphological and bio-ecological species characteristics. The results of the field study fulfilled in 2012-2014 in Krasnosamarsky forestry (Samara region) were used to determine morphometric parameters of Fritillaria ruthenica plants. The data also helped us to assess the variability level and to make a comparison with plant quantitative traits given in the literature. It was found that the shoot length of Fritillaria ruthenica plants from model biotope in Krasnosamarsky forest in 2012-2014 varied in the range of 20 ... 70 cm, in 2012 and 2013 individuals with long shoots about 50 cm dominated, in 2014 - with shoot length about 50 and 60 cm. The feature of the shoot length is characterized by plasticity, the highest level of variation was observed in 2013. The lengths of shoots are inside the range specified for the various parts of the area in the literature with a significant proportion of tall plants in the studied population. This may be a sign of good growth conditions for Fritillaria ruthenica that gives an opportunity to the plant conservation in natural communities in the absence of limited anthropogenic factors.

The paper presents some preliminary results of the monitoring of Fritillaria meleagroides Partin ex Schult. et Schult. fil. and Tulipa biebersteiniana Schult. et Schult. fil. plants (category of rare and endangered plant species). The results of the field study fulfilled in 2012-2016 in two population groups of quarter 80 and cenopopulation of quarter 69 in the Krasnosamarsky forestry (Samara Region) were used to determine morphometric parameters of plant species. The data also helped us to assess the variability level and to make a comparison with plant quantitative traits given in the literature. It has been found that the sample indicators fit into the range of values specified in literature sources, with a significant proportion of large fruit 2,0-3,0 cm in length. The dynamics of the fruit size of Fritillaria meleagroides Partin ex Schult. et Schult. fil. and Tulipa biebersteiniana Schult. et Schult. fil. plants in population groups of quarter 80, as a whole, has general patterns in the difference during some seasons of vegetation. Prevailing values of fruit length of plants in cenopopulations of quarter 69 changed slightly according to year of vegetation, these populations are more resistant and numerous comparing with the populations of quarter 80. As for variability of signs, the values of fruit length and width coefficients of variation does not exceed 25% for Fritillaria meleagroides Partin ex Schult. et Schult. fil. plants and 20% for Tulipa biebersteiniana Schult. et Schult. fil. plants which is optimal for this type of indicators and is consistent with the bioecological specificity of fruit plant. The conditions of ecosystems in 69 and 80 quarters of Krasnosamarsky forestry are favorable for the vegetation of two species plants, the successful preservation and restoration in natural communities can be in the absence of anthropogenic factors limits.

Abstract Background Frailty is common in patients with heart failure (HF) and is associated with increased morbidity and mortality. A better understanding of the causes of hospitalisations and death in frail patients might help to tailor interventional strategies for these at-risk patients. Purpose We studied the cause of death and hospitalisations in ambulatory patients with HF and frailty. Methods We assessed frailty using the clinical frailty scale (CFS) in consecutive HF patients attending a routine follow-up visit. Those with CFS ≥5 were classified as frail. Mortality and hospitalisations were ascertained from medical records (updated systematically using an NHS electronic database), discharge letters, autopsy reports and death certificates. We studied the primary cause of death and hospitalisations within one year of enrolment. Results 467 patients (67% male, median (IQR) age 76 (69–82) years, median (IQR) NT-proBNP 1156 (469–2463) ng/L) were enrolled. 206 (44%) patients were frail. Frail patients were more likely to not receive or receive suboptimal doses of ACEi/ARB and Beta-blockers; while non-frail patients were more likely to be treated with optimal doses. At 1-year follow up, there were 56 deaths and 322 hospitalisations, of which 46 (82%) and 215 (67%) occurred in frail patients. Frailty was associated with an increased risk of all-cause mortality (HR (95% CI): 4.27 (2.60–7.01)) and combined mortality/ hospitalisation (HR (95% CI): 2.85 (2.14–3.80)), all p<0.001. 57% (n=26) of frail patients died of cardiovascular causes (of which 58% were due to HF progression); although deaths due to non-cardiovascular causes (43%, n=20), especially severe infections, were also common (26%, n=12). (Figure 1) The proportion of frail patients who had non-elective hospital admissions within 1 year was more than double that of non-frail patients (46% (n=96) vs 21% (n=54); p<0.001). Compared to non-frail patients, frail patients had more recurrent (≥2) hospitalisations (28% (n=59) vs 9% (n=24); p<0.001) but median (IQR) average length of hospital stay was not significantly different (frail: 6 (4–11) vs non-frail: 6 (2–12) days, p=0.50). A large proportion of hospitalisations (64%, n=137) in frail patients were due to non-cardiovascular causes (of which 34%, 30% and 20% were due to infections, falls and comorbidities respectively). Of cardiovascular hospitalisations (36%, n=78), the majority were due to decompensated HF (67%, n=46). (Figure 1) Conclusion Frailty is common in patients with HF and is associated with an increased risk of mortality and recurrent hospitalisations. A significant proportion suffered non-cardiovascular deaths and hospitalisations. This implies that interventions targeted at HF alone can only have limited impact on outcomes in frail patients.

ABSTRACT Aim The aim of this study was to describe the characteristics and the nutritional approaches implemented with patients undergoing alcohol withdrawal. Methods A retrospective analysis of medical records for patients admitted to a tertiary hospital for alcohol withdrawal was completed over a 5-year period 2013–2017. Data on nutrition-related assessment and management were extracted and descriptively analysed. Results A total of 109 medical records were included (M = 73, F = 36), with the mean age of patients 47.3 years (SD ± 11.2, range 22–70). The average length of stay was 3.7 days (SD ± 3.9, range 0.70–27.8). Approaches towards nutritional care emerged from micronutrient assessment and supplementation and/or dietetic consultation. Nutrition-related biochemistry data was available for most patients, notably serum levels of sodium, urea and creatinine (102 patients; 93.5%) and magnesium and phosphate (66 patients, 60.5%). There was evidence of some electrolyte abnormalities on admission to hospital. Eight patients had serum micronutrient status assessed; no patients had serum thiamine levels assessed. Parenteral thiamine was provided to 96 patients (88.0%) for 1.9 days (SD ± 1.1, range 1.0–6.0) with a mean dose of 2458.7 mg (SD ± 1347.6, range 300–6700 mg). Multivitamin supplementation was provided to 24 patients (22.0%). Only 23 patients (21.2%) were seen by a dietician of whom 16 underwent a comprehensive nutritional assessment and 3 were screened using the malnutrition screening tool. Conclusion Inconsistent nutritional assessment and management practices were identified across a diverse population group, whilst nutritional professionals were underutilized. Future research should benchmark current guidelines and multidisciplinary approaches considering the role of nutritional specialists in the team.

Large bare-root liners of Gleditsia triacanthos `Moraine' and Pyrus calleryana `Aristocrat' were planted in spring, 1989. Five trees of each species were pruned by removing 50% of the length of each shoot at planting; 5 control trees were not pruned. After 4 months the trees were harvested and the following measurements were taken on the season's new growth increment: total number of elongated shoots and unelongated shoots (< 1 cm in length), total and average length of elongated new shoots, stem and leaf dry weights.Growth responses of the 2 species to treatments were nearly identical. Pruned trees had fewer shoots than controls but a much higher proportion of elongated to unelongated shoots. This could be the result of a release of apical dominance. The average new shoot length of pruned trees was 2-3 times that of controls, and the total new shoot length was significantly greater. New stem dry weights of the pruned trees were also greater than the controls, but leaf dry weights were not significantly different. Total shoot weights (stems plus leaves) were not different. In this study there was no difference between treatments in the total seasonal growth increment as measured by weight. An equivalent amount of new growth was distributed on fewer, but more rapidly-elongating branches in the pruned trees.

Abstract Introduction Solar panels are associated with a number of potential injuries from manufacturing through installation. Among these are electrical injuries, which increased in frequency with the recent increase in the production of photovoltaic panels. The burn literature is currently limited regarding these injuries, the aim of this study was to summarize our institutional experience with electrical injuries from solar panels. Methods A retrospective review of all electrical injuries evaluated at an ABA verified Burn Center from 2014–2018 was performed. Electrical burns unrelated to solar were excluded from analysis. Data collected included demographics, injury severity, and associated morbidity and mortality. Results A total of 39 electrical burns were treated during the study duration, 5 of which (13%) were related to solar panel production or installation. Two patients were burned while working in a solar factory, two while installing solar panels, and one while cleaning solar panels. The average age was 29 years (range 20–47) and all were male. All patients had &lt; 5% TBSA; 1 patient had burns to the face, 1 had burns to the foot, 2 patients had burns to the hand/finger, and 1 patient had burns including the hands, abdomen, and thigh. One patient developed v-fib following his injury. He had a prolonged hospital stay of 74 days complicated by pneumonia, encephalitis, and acute kidney injury with rhabdomyolysis causing compartment syndrome of the hand which required fasciotomy. When excluding this outlier, the average length of stay was 2 days and none required ICU care. One patient required toe amputations and one presented with corneal abrasions, but no other significant complications including cardiac arrhythmias. All 5 patients survived. Conclusions Electrical burns from solar panels make up a significant proportion of electrical burns cared for at our institution. With the recent and continued rise in solar panel production and installation, burn centers should expect to see an increase in patients presenting with electrical burns associated with these products, especially in states seeing a greater push to adopt this technology. Applicability of Research to Practice Burn center staff should be aware of this emerging pattern and prepared to care for the patient injured though this mechanism.

This assessment is based on reviews of the extent of wetland inventory in seven regions of the world. A key conclusion is that little is still known about the extent and condition of the global wetland resource. It was not possible to make reliable overall estimates of the size of the wetland resource globally or regionally. Previous estimates range from 5.3 to 9.7 million km2 but present analyses now suggest a tentative minimum of 12.8 km2. Recommendations focus on the need for national inventory programmes and the inclusion of basic information on the location and extent of each wetland and its major ecological features as a forerunner to collecting further management-oriented information. Thus, the following core data should be collected: area and boundary, location, geomorphic setting, general description, soil characteristics, water regime, water quality, and biotic characteristics. Further, the development of standardized methods for data collection, collation and storage are called for. These should address the use of remotely sensed data and storage of information in electronic formats, including Geographic Information Systems and recording key information in a meta-database. Habitats of priority for future inventory are seagrasses, coral reefs, salt marshes and coastal flats, mangroves, arid-zone wetlands, peatlands, rivers and streams, and artificial wetlands.

Introduction: Diabetic ketoacidosis (DKA) is a potentially life-threatening complication of diabetes mellitus. Recent epidemiological studies indicate that hospitalizations for DKA in the U.S. are increasing. Epidemiological studies from India are limited. We undertook this observational study to analyse the clinical profiles of DKA in adults in south India.Methods: This study was conducted in at a tertiary care center in Andhra Pradesh for one year from Aug 2010 to July 2011. Diagnosis of DKA was made by the presence of (1) Plasma glucose level of 250mg/dl or higher (2) Serum bicarbonate level of 15mEq/lt or lower (3) Arterial blood pH of 7.3 or lower or a venous blood pH of 7.25 or lower (4) Presence of moderate or large urine ketones. All the patients were treated with institutional treatment protocol.Results: Of 27 patients, 22(81%) had type2 diabetes and 5(19%) had type 1 DM .10 were females and 17 males. Age of the patients ranged between 18 to 70 years, with an average of 45.3 years. Precipitating factors were present in 60% of the admissions. Non-compliance or discontinuation of drug therapy was seen in fifty per cent of patients. Average length of hospital stay was slightly longer in type 1 than type 2 DM patientsConclusion: A significant proportion of DKA occurs in patients with type 2 diabetes and many of these cases can be prevented with proper patient education and effective communication with a health care provider during an inter-current illness.DOI: http://dx.doi.org/10.3126/hren.v10i2.6569 Health Renaissance 2012; Vol 10 (No.2); 80-86

The Impact

AbstractPersian sturgeon, Acipenser persicus Borodin, has been the most significant proportion of Iranian commercial sturgeon catches in the Caspian Sea over in the last three decades. This endemic species has suffered continuous population declines from the impact of anthropogenic factors. The present study filled in information gaps on underlying population biology parameters, evaluated the population status, and determined the vulnerability risk of the stock extinction of Persian sturgeon in the south Caspian basin of Iran. Growth parameters were L∞ = 224.7 cm, K = 0.058 years−1, t0 = -3.4 years. Sexual maturity of 50% for males and females was FL = 127.2 cm and 137.5 cm, respectively. The long-term age composition data showed 35 age groups, and the ages of 14–18 years comprised 80% of the total catch. Natural mortality was 0.123 years−1, and fishing mortality ranged between 0.104 and 0.331 years −1. The total biomass trend decreased and collapsed from 6,071.3 tons in 1990–91 to 144.1 tons in 2014–15. Although >93% of the catch included maturing specimens, the Persian sturgeon stock is now critically endangered because of several anthropogenic factors.
