Review on Databases and Bioinformatic Approaches on Pharmacogenomics of Adverse Drug Reactions.

Pharmacogenomics has been used effectively in studying adverse drug reactions by determining the person-specific genetic factors associated with individual response to a drug. Current approaches have revealed the significant importance of sequencing technologies and sequence analysis strategies for interpreting the contribution of genetic variation in developing adverse reactions. Advance in next generation sequencing and platform brings new opportunities in validating the genetic candidates in certain reactions, and could be used to develop the preemptive tests to predict the outcome of the variation in a personal response to a drug. With the highly accumulated available data recently, the in silico approach with data analysis and modeling plays as other important alternatives which significantly support the final decisions in the transformation from research to clinical applications such as diagnosis and treatments for various types of adverse responses.

Laparoscopic living donor right nephrectomy: Assessment of outcome and association of BMI to length of right renal vein. / Nefrectomía laparoscópica derecha de donante vivo: evaluación del resultado y asociación del IMC con la longitud de la vena renal derecha.

AIMS: The aim of this study was to describe outcomes of laparoscopic living donor right nephrectomy (LLDRN) and study factors affecting the length of right renal vein from the donors. MATERIAL AND METHODS: This study was conducted in 60 donors (48 males and 12 females) from January 2016 to December 2017. We performed a retrospective review of consecutive patients who underwent transperitoneal right laparoscopic living donor nephrectomy at our unit. RESULTS: LLDRN was successfully performed in all subjects by the same surgeons. Among 60 cases, 47 donors had single renal artery and vein, 2 cases had one artery and 2 veins, and 5 donors had 2 arteries and one vein, and the rest had 2-3 arteries with 1-3 veins. Operative time was 142.60±33.73min. Warm ischemic time was 2.64±0.76min. The mean hospital stay was 6.69±0.63 days. The median length of right renal vein was 1.92±0.41cm. All transplanted kidneys showed immediate function. No graft losses were recorded. Almost no gender differences were found in study variables except BMI and warm ischemic time, that was higher BMI but shorter warm ischemic time in female versus male donors. Further analysis showed a negative correlation between BMI and right renal vein (r=-0.282, P<0.05), but a positive correlation between operative time and estimate blood loss (r=0.37, P<0.01). CONCLUSIONS: LLDRN is a feasible safe procedure, less traumatic approach, and provides good outcomes kidney for recipients. Notably, in the study group the higher BMI was associated with resulting more difficult LLDRN and kidney transplantation.

Lipoxin A(4) and interleukin-8 levels in cystic fibrosis sputum after antibiotherapy.

UNLABELLED: Antibiotics are largely prescribed for cystic fibrosis (CF) respiratory exacerbations. Effects of antibiotics on the inflammatory profile of the patients have been shown but remain controversial. Lipoxin A(4) (LXA(4)) is a lipid mediator, reported to play a central role in resolving airway inflammation. The aim of the study was to investigate the consequences of antibiotherapy on LXA(4) and IL-8 levels in CF patients' airways. METHODS: Eighteen CF patients (7 females, median age 20, range 8 to 47 years) consecutively admitted at the CF center of Montpellier for antibiotics during pulmonary exacerbation, were enrolled. Before and after antibiotics, all patients underwent spirometry (FEV(1) and FVC), bacterial cultures and cell counts in sputa. IL-8 and LXA(4) concentrations were determined in sputum samples by the median of immunometric assays. RESULTS: As previously reported, after antibiotics therapy, FEV(1) and FVC significantly improved. While neutrophil cell counts and IL-8 levels decreased, the LXA(4) levels significantly increased after antibiotics therapy and were inversely correlated with IL-8 levels. In conclusion, we reported a correlation between antibiotics treatments and inflammatory markers in CF sputum. Our data provide evidences for a novel effect of antibiotics increasing the concentration of the anti-inflammatory lipid mediator LXA(4).

Parasitic infections in dairy cattle around Hanoi, northern Vietnam.

In northern Vietnam, dairy cattle are mainly managed in small-scale farms, where animals are kept confined and feeding occurs by cut and carry methods. In the present study the occurrence of parasitic infections was examined in five provinces around Hanoi. A total of 201 farms were visited, and 334 stool and 239 blood samples were collected from calves younger than 3 months, animals between 3 and 24 months and adult cows. Furthermore, 254 milk samples were collected from lactating animals. Coproscopical examination indicated a high prevalence of nematode eggs (Cooperia spp., Haemonchus and Oesophagostomum spp.) in animals (n=176) between 3 and 24 months (66%) and in adult cows (n=90; 54%). In these age groups the prevalence of Fasciola was 28% and 39%, respectively, and for Paramphistomum the prevalence was 78% and 82%, respectively. Fifty percent of the calves younger than 3 months (n=68) were positive for Giardia, and none for Cryptosporidium. Most Giardia isolates were identified as the non-zoonotic G. duodenalis assemblage E on the beta-giardin gene. The blood samples were examined with commercially available Svanovir((R))Elisa's for the presence of Anaplasma marginale and Babesia bigemina specific antibodies, and a prevalence of 28% and 54% was found, respectively. In the milk samples Neospora caninum specific antibodies (Svanovir((R))Elisa) were detected in 30% of the lactating animals. The present study demonstrates that parasitic infections occur frequently in dairy cattle around Hanoi although animals are mainly kept confined, and indicates that further research on the economic impact of these infections is needed.
