474 Productive and reproductive performance of Goat Breeds of Sindh

The study was carried out in Sindh province of Pakistan to investigate productive and reproductive performance of ten local goat breeds. The ten goat breeds included in the study were Kamori, Tapri, Bugi-Turi, Pateri, Kachan, Jattan, Lohri, Chappar, Barri, and Thari. The data were collected using a detailed survey on various productive (birth weight, weaning weight, weaning age, average daily gain, milk yield and lactation length) and reproductive (age at first heat, age at first kidding, kidding interval, service period, number of services per conception and twinning percentage) traits of goats. Up sixteen local farmers of each breed were visited by the investigators and information was recorded/collected on prescribed performas. The highest birth weight was observed in Pateri goat (2.90 ± 0.11kg). In case of weaning weight maximum was observed in Kachan (16.0 ± 0.50kg) and lowest in Thari (11.19 ± 0.40 kg). Moreover weaning age was lowest in Thari (3.0 ± 0.11months) and highest was in Bugi-Turi (8.0 ± 0.14months). The highest milk yield was observed in Tapri and Kamori (~ 3.50 kg) followed by Pateri (~2.90 kg), Bugi Tori, Kacchan, Jattan (~ 2.00 kg) and Lohri, Chapper, Barri and Theri (~1 kg). As far as reproductive traits are concerned; age at first heat was lowest in Pateri (around 7 months) while all other breeds ranged from 11 to 15 months). The maximum twining percentage at first kidding was observed in Chappar (25%). Jattan had lowest kidding interval (5.0 ± 0.16 months). On the basis of overall average pre-weaning growth rate of kids, Tapri and Thari appear to have higher growth potential followed by Kamori and Kachhan. It could be concluded that Tapri, Thari and Kamori may be utilized for meat production under existing circumstances in the order of priority. Similarly, Tapri, Kamori and Pateri may be better utilized as dairy goats as well.

Green Synthesis of Hydrophobic Magnetite Nanoparticles Coated with Plant Extract and Their Application as Petroleum Oil Spill Collectors

In this study, an easy, rapid and eco-friendly method was used successfully to synthesize the magnetite nanoparticles (MNPs). In order to fine-tune the synthesized MNPs for the collection of heavy crude oil spills, the particles’ surface was modified with green hydrophobic biocomponents that were extracted from Anthemispseudocotula (AP). The surface modified reaction carried with that of the MNPs in the presence of n-hexane extract (APH) resulted in the formation of APH-MNPs, while in the presence of chloroform extract (APC), resulted in APC-MNPs formation. The as-formed MNPs were thoroughly characterized using transmittance electron microscopy, X-ray powder diffraction, vibrating sample magnetometer and thermogravimetric analysis. The efficiency of the surface-modified MNPs for the collection of oil spills in the presence of an external magnetic field was evaluated by taking different ratios of MNPs:crude oil. From the analysis of the results, we found that the APH-MNPs particles have higher efficiency in the collection of heavy crude oil than the corresponding APC-MNPs.

Urban HEART Detroit: a Tool To Better Understand and Address Health Equity Gaps in the City

The Urban Health Equity Assessment Response Tool (Urban HEART) combines statistical evidence and community knowledge to address urban health inequities. This paper describes the process of adopting and implementing this tool for Detroit, Michigan, the first city in the USA to use it. The six steps of Urban HEART were implemented by the Healthy Environments Partnership, a community-based participatory research partnership made up of community-based organizations, health service providers, and researchers based in academic institutions. Local indicators and benchmarks were identified and criteria established to prioritize a response plan. We examine how principles of CBPR influenced this process, including the development of a collaborative and equitable process that offered learning opportunities and capacity building among all partners. For the health equity matrix, 15 indicators were chosen within the Urban HEART five policy domains: physical environment and infrastructure, social and human development, economics, governance, and population health. Partners defined the criteria and ranked them for use in assessing and prioritizing health equity gaps. Subsequently, partners generated a series of potential actions for indicators prioritized in this process. Engagement of community partners contributed to benchmark selection and modification, and provided opportunities for dialog and co-learning throughout the process. Application of a CBPR approach provided a foundation for engagement of partners in the Urban HEART process of identifying health equity gaps. This approach offered multiple opportunities for discussion that shaped interpretation and development of strategies to address identified issues to achieve health equity.

Optimized laser-induced breakdown spectroscopy for the determination of high toxic lead in edible colors

An optimized laser-induced breakdown spectroscopy (LIBS) system was utilized as a robust tool for the detection of high toxic lead (Pb) in often used edible colors available in local markets. Edible colors are extensively used in different food stuffs and sweet dish items. To attain a highly sensitive LIBS system for the determination of trace amounts of toxic Pb in edible colors and to achieve the best detection limit, various parametric dependence studies were performed. The quantitative determinations were accomplished under the condition of local thermodynamic equilibrium in terms of optically thin plasma. Besides toxic Pb, other elements like Ca, Mg, Fe, and Na were also detected in edible colors. To estimate the concentration of toxic lead in edible colors, calibration curves were plotted by preparing standard samples of different lead concentrations in an edible colors matrix. Results of the LIBS technique were compared with the outcomes of the same samples studied using a standard analytical technique of inductively coupled plasma-optical emission spectroscopy to confirm the contemporary LIBS setup. The color samples were found above the safe permissible level due to the mass of toxic lead. Limit of detection of the LIBS setup was found at 0.86+/-0.03  ppm for toxic lead present in edible color samples.

Alterations in endothelin receptors following hemorrhage and resuscitation by centhaquin

Endothelin-1 (ET-1) acts on ET(A) and ET(B) receptors and has been implicated in hemorrhagic shock (shock). We determined effect of shock and resuscitation by hypertonic saline (saline) or centhaquin on ET(A) and ET(B) receptor expression. Rats were anesthetized, a pressure catheter was placed in the left femoral artery; blood was withdrawn from the right femoral artery to bring mean arterial pressure (MAP) to 35 mm Hg for 30 min, resuscitation was performed and 90 min later sacrificed to collect samples for biochemical estimations. Resuscitation with centhaquin decreased blood lactate and increased MAP. Protein levels of ET(A) or ET(B) receptor were unaltered in the brain, heart, lung and liver following shock or resuscitation. In the abdominal aorta, shock produced an increase (140 %) in ET(A) expression which was attenuated by saline and centhaquin; ET(B) expression was unaltered following shock but was increased (79 %) by centhaquin. In renal medulla, ET(A) expression was unaltered following shock, but was decreased (-61 %) by centhaquin; shock produced a decrease (-34 %) in ET(B) expression which was completely attenuated by centhaquin and not saline. Shock induced changes in ET(A) and ET(B) receptors in the aorta and renal medulla are reversed by centhaquin and may be contributing to its efficacy.

Surgical management of focal ionising radiation burns

The management of focal radiation burns after prolonged exposure to ionising radiation remains a relatively rare but significant therapeutic challenge. This narrative aims to highlight certain aspects of management that can be overlooked and mitigation strategies in the management of these potentially fatal injuries.

Emergent management of the suspected pelvic fracture: challenges in the obese patient

Pelvic fractures, although infrequent, are a significant cause of morbidity and mortality in the trauma population. Currently, the mainstay of emergent management of a suspected pelvic fracture is placement of a pelvic binder, and their use in the prehospital setting is recommended for any individual involved in high-energy trauma. Obesity in the trauma patient has been shown to be an independent risk factor of morbidity and mortality, and the incidence of pelvic and lower extremity fractures has consistently demonstrated to be higher in the obese patient compared with an individual with a normal body habitus. This article aims to highlight the challenges associated with pelvic fracture in the obese population.

Delayed presentation of grade-IV renal injury post blunt trauma

High-grade renal injuries are relatively uncommon in blunt trauma. They typically occur in the context of multisystem injuries. When present, these renal injuries are usually identified at the time of hospital presentation. Here, we present a case of delayed presentation of American Association for the Surgery of Trauma (AAST) grade-IV renal injury in a 61-year-old female who sustained multisystem injuries during a high-speed motor vehicle accident. To our knowledge, this is the first report case of delayed presentation of grade-IV renal injury. This case highlights the importance of serial examination and repeated imaging in complex trauma patients.

Radiation-Induced Myelitis: Initial and Follow-Up MRI and Clinical Features in Patients at a Single Tertiary Care Institution during 20 Years

Myelitis is a rare complication of radiation exposure to the spinal cord and is often a diagnosis of exclusion. A retrospective review of clinical records and serial imaging was performed to identify subjects with documented myelitis and a history of prior radiation. Eleven patients fulfilled the inclusion criteria. All patients had longitudinally extensive cord involvement with homogeneous precontrast T1 hyperintense signal in the adjacent vertebrae, corresponding to the radiation field. T2 signal abnormalities involving the central two-thirds of the cord were seen in 6/11 patients (55%). The degree of cord expansion and contrast enhancement was variable but was seen in 6 (54%) and 5 (45%) patients, respectively. On follow-up, 2 patients developed cord atrophy, while complete resolution was noted in 1. Clinical improvement was noted in 5 patients, with symptom progression in 2 patients. Our results suggest that radiation myelitis is neither universally progressive nor permanent, and some radiographic and clinical improvement may occur.

Optimal ventilator strategies for trauma-related ARDS

BACKGROUND

Acute respiratory distress syndrome (ARDS) was first described in the 1960s and has become a major area of research due to the mortality and morbidity associated with it. ARDS is currently defined using the Berlin Consensus; however, this is not wholly applicable for trauma-related ARDS.

METHODS

A systematic review of the literature was undertaken using the Preferred Reporting for Systematic Reviews and Meta Analyses methodology. The Ovid Medline, Web of Science and PubMed online databases were interrogated for papers published between 1 January 1995 and 31 December 2017.

RESULTS

The literature search yielded a total of 64 papers that fulfilled the search criteria.

CONCLUSIONS

Despite decades of dedicated research into different treatment modalities, ARDS continues to carry a high burden of mortality. The ARDS definitions laid out in the Berlin consensus are not entirely suited to trauma. While trauma-related ARDS represents a small portion of the available research, the evidence continues to favour low tidal volume ventilation as the benchmark for current practice. Positive end expiratory ventilation and airway pressure release ventilation in trauma cohorts may be beneficial; however, the evidence to date does not show this.

The Pattern of Serum Calcium, Phosphate and Parathyroid Hormone Levels in Pre-Diagnosed Chronic Kidney Disease Patients

Chronic kidney disease (CKD) is an international health problem affecting 5-10% of the world population. Patients with chronic kidney disease were known to have higher prevalence of changes in serum calcium, phosphate and parathyroid hormone in Western countries, but data on the impact of CKD on serum calcium, phosphate and parathyroid hormone in our country are scarce. This cross-sectional type of descriptive study was conducted in the Department of Medicine, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from March 2016 to September 2016. The aim of this study is to estimate serum calcium, phosphate and parathyroid hormone levels in chronic kidney disease (CKD) patients for early recognition of abnormalities, understanding of their patho-physiological consequences & planning management strategies to prevent their progression, thus reducing the morbidity & mortality. This study shows Hypocalcemia, hyperphosphataemia and elevated serum PTH levels are noted in later CKD stages & worsen with disease progression.
