Erythrocyte fatty acids and desaturase indices in early pregnancy are associated with risk of preeclampsia.

Preeclampsia (PE) is a pregnancy disorder that may be associated with inadequate maternal nutrition. Fatty acids are vital for placental and fetal growth. Fatty acid desaturases, key enzymes influencing the metabolism of polyunsaturated fatty acids, are reported to be associated with cardiometabolic risk. Any imbalance in the levels of omega-3 and omega-6 fatty acids can result in increased inflammatory response. The current study reports the levels of erythrocyte fatty acids and desaturase index across gestation in women who develop PE (n = 108) and compares them with non-PE women (n = 216). Maternal erythrocyte fatty acids were measured at 4 time points during pregnancy (i.e., 11-14, 18-22, 26-28 weeks and at delivery) using gas chromatography. Maternal total erythrocyte saturated fatty acids and omega-6/omega-3 fatty acid ratio was higher in the PE group as compared to the non-PE group at 11-14 weeks and 18-22 weeks respectively. Maternal Δ5 desaturase index was lower while Δ6 desaturase index was higher in the PE group at 11-14 and 18-22 weeks. Maternal stearoyl CoA desaturase-18 (SCD-18) index was lower at 11-14 weeks and at delivery. These changes were mainly observed in the early onset PE (EOP) group. Δ6 desaturase index at 11-14 weeks predicted the risk of EOP. Imbalance in fatty acid levels and desaturase indices predate the clinical diagnosis of PE, indicating their role in its pathophysiology. Measurement of fatty acids and desaturase indices in early pregnancy merits evaluation as predictors of risk of PE.

Minimizing Hepatic Artery Thrombosis and Establishing Safety of Grafts With Dual Arteries in Living Donor Liver Transplantation.

BACKGROUND: Hepatic artery thrombosis (HAT) is a dreaded complication following living donor liver transplantation (LDLT) and can lead to graft failure and biliary complications. We evaluated the results of our arterial anastomotic technique and outcomes in grafts with dual arterial supply. PATIENTS AND METHODS: Between July 2010 and June 2015, 225 patients underwent LDLT. The hepatic artery anastomosis was done using our "W technique". In grafts with a dual arterial supply, two anastomoses were performed unless there was significant pulsatile back-bleeding in the smaller artery after the larger anastomosis. RESULTS: The mean age of the recipients was 43±15.2 years (6 months to 66 years). There were 184 right liver, 30 left liver, 10 left lateral segment, and 1 dual lobe (right liver and left lateral segment) grafts. Twenty-three (10.2%) patients had 2 graft arteries, 10 of which required 2 separate anastomoses, and an interposition saphenous vein conduit was used in one. HAT occurred in 3 (1.3%) patients. The median intensive care unit and postoperative hospital stays were 5 and 14 days, respectively. Post-transplant operative mortality was 12.4%. There was no difference in mortality (8.7% vs 12.4%, P = >.99) and biliary complications (11.9% vs 21.7%, P = .19) between recipients of grafts with single or dual graft arteries, respectively. CONCLUSIONS: A careful surgical "W technique" and intraoperative confirmation of a good arterial flow helps in reducing the incidence of early HAT. The presence of two arteries in the graft was not associated with increased incidence of HAT, mortality, or biliary complications.

Effect of informed consent on patients undergoing gastrointestinal surgery and living donor liver transplantation and on their relatives in a developing country.

BACKGROUND: Informed consent is a systematic process for obtaining permission before conducting a healthcare intervention. In a developing country, gaining informed consent is generally perceived to be a ritual only to comply with legal requirements. The present study examined this by assessing the process of informed consent in patients undergoing gastrointestinal surgery or living donor liver transplantation (LDLT) and their relatives, based on their comprehension and overall satisfaction, in India. METHODS: All patients undergoing any gastrointestinal surgery or LDLT procedure between August 2015 and July 2016 and their relatives were included, and were administered a structured questionnaire 5 days after the procedure. RESULTS: The majority of patients (94·2 per cent) could recall the nature of their disease, the surgery performed (81·6 per cent) and anticipated complications (55·6 per cent). Among their relatives, these proportions were 97·8, 87·3 and 58·5 per cent respectively. Recall was associated with age, occupation and education among both patients and relatives. Patients undergoing LDLT, their donors and their relatives had better recall than those who had other gastrointestinal procedures (P < 0·001). Many patients found the process of informed consent useful and reassuring. CONCLUSION: The details and risks of an operation were understood by most of the patients, especially those undergoing liver transplantation. Patients from developing countries can generally understand 'informed consent', and value it.

Efficacy, Immunogenicity, and Safety of a 9-Valent Human Papillomavirus Vaccine: Subgroup Analysis of Participants From Asian Countries.

Background: A 9-valent human papillomavirus-6/11/16/18/31/33/45/52/58 (9vHPV) vaccine extends coverage to 5 next most common oncogenic types (31/33/45/52/58) in cervical cancer versus quadrivalent HPV (qHPV) vaccine. We describe efficacy, immunogenicity, and safety in Asian participants (India, Hong Kong, South Korea, Japan, Taiwan, and Thailand) from 2 international studies: a randomized, double-blinded, qHPV vaccine-controlled efficacy study (young women aged 16-26 years; NCT00543543; Study 001); and an immunogenicity study (girls and boys aged 9-15 years; NCT00943722; Study 002). Methods: Participants (N = 2519) were vaccinated at day 1 and months 2 and 6. Gynecological samples (Study 001 only) and serum were collected for HPV DNA and antibody assessments, respectively. Injection-site and systemic adverse events (AEs) were monitored. Data were analyzed by country and vaccination group. Results: 9vHPV vaccine prevented HPV-31/33/45/52/58-related persistent infection with 90.4%-100% efficacy across included countries. At month 7, ≥97.9% of participants seroconverted for each HPV type. Injection-site AEs occurred in 77.7%-83.1% and 81.9%-87.5% of qHPV and 9vHPV vaccine recipients in Study 001, respectively, and 62.4%-85.7% of girls/boys in Study 002; most were mild to moderate. Conclusions: The 9vHPV vaccine is efficacious, immunogenic, and well tolerated in Asian participants. Data support 9vHPV vaccination programs in Asia. Clinical Trials Registration: NCT00543543; NCT00943722.

Does the presence of Klebsiella pneumoniae carbapenemase and New Delhi metallo-ß-lactamase-1 genes in pathogens lead to fatal outcome?

INTRODUCTION: Infections due to multidrug-resistant (MDR) pathogens are a medical challenge. There is considerable apprehension among clinicians regarding pathogens reported as carrying New Delhi metallo-ß-lactamase-1 (NDM) and Klebsiella pneumoniae carbapenemase (KPC) genes from their patients. In the face of extremely high rates of antimicrobial resistance, it is essential to gauge the clinical significance of isolation of pathogens carrying these genes from clinical samples. This study compares the outcome of patients infected with pathogens carrying NDM/KPC genes versus those without these genes. METHODS: The study was conducted over a 1-year period at a Level-1 trauma centre. Hospital-acquired infections were diagnosed on the basis of CDC's criteria. The correlation of isolation of a multi-resistant pathogen carrying KPC or NDM genes with the clinical outcome was ascertained. RESULTS: A total of 276 consecutive patients admitted to the Intensive Care Units/wards of the JPNA Trauma Centre were included in this study. Of the 371 isolates recovered from these patients, 116 were from patients who had a fatal outcome. The difference in prevalence of blaNDMand blaKPCwas not significant in any genera of Gram-negative pathogens isolated from patients who survived versus those who had a fatal outcome. CONCLUSION: Isolation of MDR pathogens carrying NDM/KPC genes from clinical samples is not always a harbinger of a fatal outcome. Efforts should be made to prevent cross-transmission of these pathogens.

Endoscopic management of post-liver transplant billiary complications: A prospective study from tertiary centre in India.

BACKGROUND: Liver transplantation has become common in India over the last decade and biliary strictures after the procedure cause a significant morbidity. Endoscopic retrograde cholangiopancreatography (ERCP) is a safe and effective treatment modality for post-transplant biliary strictures so we decided to evaluate prospectively the outcomes of endoscopic treatment in post-living donor liver transplantation (LDLT) biliary strictures. METHODS: We studied ten consecutive patients who had developed biliary strictures (out of 312 who had undergone liver transplantation between June 2009 and June 2013) and had been referred to the Department of Gastroenterology for management. All patients underwent liver function tests, ultrasound of the abdomen, magnetic resonance cholangiography and liver biopsy, if this was indicated. RESULTS: Of these 312 patients who underwent liver transplantation, 305 had living donors (LDLT) and 7 deceased donors (DDLT). Ten patients in the LDLT group (3.3%) developed biliary strictures. There were seven males and three females who had median age of 52 years (range 4-60 years). The biliary anastomosis was duct-to-duct in all patients with one patient having an additional duct-to-jejunum anastomosis. The mode of presentation was cholangitis in four patients (40%), asymptomatic elevation of liver enzymes in four (40%) and jaundice in two patients (20%). The median time from transplantation to the detection of the stricture was 12 months (2-42.5 months). ERCP was attempted as initial therapy in all patients: seven were managed entirely by endoscopic therapy, and three required a combined percutaneous and endoscopic approach. Cholangiography demonstrated anastomotic stricture in all patients. A total of 32 sessions of ERCP were done with mean of 3.2 (2-5) endoscopic sessions and 3.4 (1-6) stents required to resolve the stricture. The median time from the first intervention to stricture resolution was 4 months (range 2-12 months). In four patients, the stents were removed after one session and in two patients each after two, three and four sessions. In six patients more than one stent was placed and all of them required dilatation of stricture. Seven patients completed treatment and are off stents at a median follow up period of 9.5 months (7-11 months). Two patients developed recurrence of their stricture after 7.5 months. Both had long strictures and required a combined endoscopic and percutaneous approach. There was one mortality due to sepsis secondary to cholangitis. CONCLUSIONS: Post-LDLT biliary strictures can be successfully treated with ERCP, and most patients remain well on follow up (median 9.5 months). A combined endoscopic and percutaneous approach is useful when ERCP alone fails.

Device-associated infections at a level-1 trauma centre of a developing nation: impact of automated surveillance, training and feedbacks.

PURPOSE: Device-associated infections constitute the majority of health care-associated infections (HAIs) in ICUs. Trauma patients are predisposed to acquire such infections due to various trauma-related factors. The prevalence of HAIs is underreported from developing nations due to a lack of systematic surveillance. This study reports the impact of an intensive surveillance on the rates and outcome of device-associated infections in trauma patients from a developing country and compares the rates with a previous pilot observation. MATERIALS AND METHODS: The study was conducted at a level-1 trauma centre of India. Surveillance for ventilator-associated pneumonia (VAP), central line-associated blood stream infections (CLA-BSIs) and catheter-associated urinary tract infections (CA-UTIs) was done based on centre for disease control-National Healthcare Safety Network (CDC-NHSN) definitions. The impact of an intensive surveillance, education and awareness drive on the rates of infections over the study period, and compliance to preventive bundles and hand hygiene was assessed. RESULTS: A total of 15,462 ventilator days, 12,207 central line days and 17,740 urinary catheter days were recorded in the study population. The overall rates of VAP, CLA-BSI and CA-UTI were respectively 17, 7.2 and 15.5/1000 device days. There was a significant correlation between device days and the propensity to develop infections. Infections were the cause of death in 36.6% of fatal trauma cases. A significantly higher rate of VAP, CLA-BSI and CA-UTIs was noted in fatal cases. The compliance to ventilator bundle, central line bundle, bladder bundle and hand hygiene were 74.5%, 86%, 79.3% and 64.6%, respectively. A high rate of multi-drug-resistance was observed in all pathogens. A gross reduction in the rates of all infections was observed over time during the study due to implementation of a stringent surveillance system, feedbacks and education. The compliance to hand hygiene and preventive bundles also increased over time. CONCLUSION: The automated surveillance was easy and useful for data entry and analysis. Surveillance had a significant impact on reduction of HAIs and mortality in trauma patients.

Mortality profile of patients with traumatic spinal injuries at a level I trauma care centre in India.

BACKGROUND & OBJECTIVES: There is no national spinal trauma registry available in India at present and the research on epidemiology of these injuries is also very limited. The purpose of this study was to describe the mortality profile of patients with spinal injuries brought to a level I trauma centre in India, and to understand the predictive factors which identify patients at an increased risk of spinal trauma mortality. METHODS: Retrospective data were collected from computerized patients records and autopsy reports maintained in the department of Forensic Medicine. All the cases with spinal injuries whether in isolation or as a part of polytrauma were reviewed. A total of 341 such cases were identified between January 2008 to December 2011. The demographic data, type of trauma, duration of survival, body areas involved, level of spinal injury and associated injuries if any, were recorded. RESULTS: There were 288 (84.45%) males and 53 (15.55%) females. Most victims (73%) were between 25 and 64 yr of age, followed by young adults between 16 and 24 yr (19.35%). Male: female ratio was 5.4:1. Fifty five per cent cases had spinal injuries in isolation. Injury to the cervical spine occurred in 259 (75.95%) patients, thoracic spine in 56 (16.42%) and thoraco-lumbar spine in 26 (7.62%) patients. The commonest cause of injury was high energy falls (44.28%), followed by road traffic accidents (41.93%). The majority of deaths (51.6%) occurred in the phase IV (secondary to tertiary complications of trauma, i.e. >1 wk). Forty patients died in phase I (brought dead or surviving <3 h), 55 in phase II (>3 to 24 h) and 70 in phase III (> 24 h to 7 days). INTERPRETATION & CONCLUSIONS: Our data suggest that there is an urgent need to take steps to prevent major injuries, strengthen the pre-hospital care, transportation network, treatment in specialized trauma care units and to improve injury surveillance and the quality of data collected which can guide prevention efforts to avoid loss of young active lives.

Diagnosis of ventilator-associated pneumonia: comparison between ante-mortem and post-mortem cultures in trauma patients.

PURPOSE: To evaluate the diagnostic utility of ante-mortem tracheal aspirates for diagnosis of ventilator-associated pneumonia (VAP). Trauma victims represent an otherwise healthy population, who are on multiple invasive life-support devices, which predispose them to severe infections like VAP. The diagnosis of VAP is challenging, due to the difficulty in obtaining a representative sample from lungs. We studied the diagnostic utility of tracheal aspirates by comparing its results with the post-mortem lung cultures. MATERIALS AND METHODS: A total of 106 fatal trauma patients were included in the study. Lung samples and cardiac blood were taken for culture at the time of autopsy. The results of ante-mortem and post-mortem cultures were compared. RESULTS: Septicemia was the cause of death in 51 (48%) of the fatal cases and VAP was identified in 36 (34%) cases. A total of 96 (90.5%) cases had pathogens isolated from lung samples. In 62 (58%) cases, the same organism was isolated from ante-mortem and post-mortem respiratory samples. CONCLUSIONS: Culture results of a properly collected tracheal aspirate should be taken into consideration along with Centre for Disease Control and Prevention (CDC's) diagnostic criteria to maximise the diagnosis of VAP.

E-suicide note: A newer trend and its medico-legal implications in India.

Rapid advancements of information and communication technology in the form of electronic mails, mobile phones, social networking sites, etc have an increasing impact on people's day to day life. It has been observed that these readily available applications are used frequently to express suicidal intentions. There are many studies on conventional handwritten suicide notes but suicide note in electronic format is an emerging issue and an under-researched phenomena. The authors have termed it as "E-suicide note" and discuss its medico-legal implications in India with examples from their observations.

Mortality due to septicemia at a level 1 Indian trauma care centre: an epidemiological analysis.

Trauma contributes to a significant proportion of mortality and morbidity in the economically productive age group of 15-45 years. Infections are the second most important cause of death in trauma patients after head injury. Despite advances in trauma care, deaths due to septicemia are increasing. An epidemiological study of septicemia-related deaths were conducted at a level 1 Trauma Centre from January 2011 to December 2011. A total of 201 patients died due to suspected septicemia. The average age of the deceased trauma victims was 35.9 years and the median length of stay in hospital before death was 27 days. In our study, a high proportion of patients had grown pathogens in significant counts from respiratory specimens (36%) and blood (23%) during ante-mortem period, which may have contributed to their fatal outcome. Infections are one of the most common and fatal complications following trauma and complicate the recovery of a significant number of injured patients.

Management of diabetic ketoacidosis in PICU.

OBJECTIVE: This study was undertaken to analyze the outcome of children with DKA treated with a modified protocol at a tertiary level teaching hospital PICU in Pune, Maharashatra. METHODS: We retrospectively analyzed case records of 12 patients (8 males and 4 females) with DKA (11 new and 1 readmission) admitted in our PICU from January 2005 to June 2006. Patients were managed according to a modified protocol (that is with less intensive biochemical monitoring when compared with standard book protocols). Laboratory parameters measured were blood glucose, urinary ketones, electrolytes, urea creatinine, arterial blood gas (ABG) and infectious screen. Treatment included fluid therapy and insulin infusion- 0.1 u/Kg short acting intravenously followed by 0.1 u/Kg/hr. No bicarbonate was administered as a bolus. RESULTS: Total fluid deficit was corrected slowly over a period of 36 hr. The median time to normalize ABG was 19 hr (5.3-39) while the median time for the urinary ketones to disappear was 1day (1-3). The child to nurse ratio was 1:2, there were 2 pediatric residents in house all 24 hr with an intensivist and pediatric endocrinologist on call. CONCLUSION: We have shown that when DKA is managed in a PICU setting using modified protocol, the outcome is good and complications such as brain edema can be prevented.

Skeleton used for anatomical study brought for medico-legal autopsy: a case report.

Knowledge of human anatomy is essential for all those practising medicine. The human skeleton is invariably used to study the anatomy of body structures. For this, many human skeletons are obtained from the market by students and teachers and are kept at home or in hostel rooms. However, after use the skeleton has to be disposed off properly. In the present case, a human skeleton used for study purposes was thrown away in garbage and someone informed the police about presence of skeletal remains in the garbage. The case was registered by the police and the skeletal remains were brought for medico-legal autopsy.

Fatal pulmonary oedema following laparoscopic chromopertubation.

The body of a 30-year-old woman was received for autopsy. The available medical case records mentioned that she had been married for the past 3 years and had had primary infertility. She had undergone a diagnostic-cum-operative laparoscopy under general anaesthesia in a private nursing home. On laparoscopy, the internal genital organs were normal except for a fimbrial cyst on each side. Chromopertubation was done using methylene blue dye along with diagnostic dilatation and curettage. The patient was extubated and shifted to the recovery room. About 15 minutes later she developed cyanosis and became unconscious. She died despite sustained efforts at resuscitation.

Fatal occupational injuries in the South Delhi construction industry: a retrospective study.

One hundred and forty-five unselected autopsy cases of construction site accidents received from South Delhi were studied during the period from 1996--2002. Data for the study was gathered from autopsy reports and hospital records. The cases represented approximately 1.61% of all autopsy cases received from South Delhi at the All India Institute of Medical Sciences, New Delhi (India). Data was analysed with regard to the age and sex of the victim, the part of the body involved, the manner of accident, the cause of death and the pattern of injuries in different body regions. Death occurred at the scene of the fatal event in thirty-four cases; forty-three cases were dead on arrival at the hospital; sixty-eight cases died after being admitted to the hospital. Ethanol was detected in the blood of 16% of the cases.

A fatal impaling injury in a road traffic accident: a case report.

A 17-year old, thin-built male was sitting in a bus on the right side of the rear seat. The same side of the bus accidentally hit some iron rods, meant for construction work, projecting from the tail end of a small truck. The incident happened when the bus driver tried to manoeuvre the bus towards the left side of the truck, standing at a red traffic light intersection. One of the iron-rods entered the bus through the glass window next to which the victim had been sitting and penetrated his chest cavity from the side, lacerating both the lungs and exiting through the left shoulder blade. The individual died on his way to hospital.

Problems with evidence-based medicine.

Evidence-based medicine is a modern paradigm by which to practice clinical medicine. It is rapidly gaining acceptance among academicians and clinicians as the optimal way to care for patients. Modern technology has facilitated easy access to information, improving the ability to put evidence-based medicine into practice. Data demonstrating its value are accumulating; however, like any innovation, evidence-based medicine has come under attack for a variety of shortcomings. These problems are both secondary to misapplication of basic principles inherent to the concept. (J Am Assoc Gynecol Laparosc 6(2):237-240, 1999)
