The influence of PROP taster status on habitual sweet food consumption and dietary intake amongst obese and non-obese adults

@#Introduction: Ability to taste 6-n-propylthiouracil (PROP) predicts both taste sensitivity and food preferences, with PROP tasters being more sensitive to sweet taste in foods, which may lead to less intake of sugary foods. However, when obesity progresses, the individual’s sense of taste and eating patterns may change. The aim of this study was to evaluate if PROP taster status affected habitual sweet food consumption and nutritional intake in obese and non-obese people. Methods: A total of 88 obese and 92 non-obese Malay male and female participants aged 20-45 years were classified into PROP non-tasters, medium tasters, or supertasters by using PROP filter paper screening procedure. Sweet food consumption was assessed using food frequency questionnaire (FFQ), while dietary intake was measured by using 3-day food diary. Data were analysed using General Linear Model (GLM) Analysis of Covariance (ANCOVA) to compare for differences and associations among variables. Results: Overall, there was no significant association between body mass index groups and PROP taster status (p>0.05). No significant differences were found on any habitual sweet food intake and dietary intake according to PROP taster status in both obese and non-obese participants (p>0.05). However, there was a significant difference (p<0.05) in fruit intake according to PROP taster status among obese participants. Conclusion: The findings suggest that PROP taster status does not play a role in nutrient intakes among obese and non-obese individuals.

Association Between TAS1R2 Gene Polymorphism (rs12033832) and Sweet Taste Perception Amongst Malay Obese and Nonobese Subjects

@#Introduction: A growing evidence supported that variation of sweet taste perception, mediated by TAS1Rs gene variants could lead to excess sweetened food and beverages intake and also obesity. However, obesity development may also alter individuals' taste sensitivity and perception. Thus, it is best to further investigate whether or not the individuals' sweet taste sensitivity and acceptance are associated with variation in TAS1R2 gene and Body Mass Index (BMI) status. Methods: This comparison cross sectional study comprised of 88 obese and 92 non-obese subjects aged 20-45. All the subjects were genotyped for TAS1R2 gene variant at rs12033832 using polymerase chain reaction – restriction fragment length polymorphism (PCR-RFLP). Suprathreshold sensitivity for sweet taste was assessed using general Labeled Magnitude Scales. Intensity rating and hedonic test were carried out on 2 food samples (tea drink and rose flavoured agar) to examine subject's intensity rating and liking at different sugar contents. Results: Our results showed that rs12033832 of TAS1R2 gene is associated with sweet taste perception among obese and non-obese subjects. No interaction effect between BMI status and TAS1R2 gene variant (rs12022832) was found on sweet taste measures. Overall, non-obese subjects with AA genotype on rs12033832 had the highest sweet taste sensitivity and dislike high sugar content products the most. The effect was reverse among the obese subjects with GG homozygous. Conclusion: These findings suggest that TAS1R2 gene variation plays an important role in sweet taste perception among individuals and may have nutritional implications and obesity.

Interleukin-10 is increased in successful drug desensitization regardless of the hypersensitivity reaction type

BACKGROUND: Little is known about the mechanism of desensitization in hypersensitivity drug reactions. OBJECTIVE: The aim of this study was to evaluate the effects of drug desensitization on some cytokine levels in patients desensitized for drug hypersensitivity reactions. METHODS: Patients with a hypersensitivity reaction to any drug for whom desensitization was planned with the culprit drug, patients who could tolerate the same drugs and healthy subjects who were not exposed to these drugs were enrolled. Bead-based Milliplex MAP multiplex technology was used to determine interleukin (IL)-4, IL-5, interferon-γ and IL-10 levels in the sera of the subjects as a baseline and 24 hours after desensitization had been completed in the patients. RESULTS: A total of 26 patients (16 female [61.5%]; mean age 48.46 ± 15.97 years old), 10 control patients (5 female [50%]; mean age 47.4 ± 15.4 years old) and 5 healthy subjects (3 female [60%]; mean age 34.2 ± 5.6 years old) were enrolled. Four of the 26 patients did not tolerate the procedure and were grouped as the ‘unsuccessful desensitization group’ whereas 22 patients successfully completed the procedure and formed the ‘successful desensitization group.’ Baseline cytokine levels in the 3 groups were not statistically different. Postdesensitization IL-10 levels in the successful desensitization group were significantly higher than their initial levels (p = 0.005) whereas none of the cytokine levels significantly changed in the unsuccessful desensitization group. The rise in IL-10 levels was greater in chemotherapeutic desensitizations when compared to other drugs (p = 0.006). CONCLUSION: Successful desensitization independent of the hypersensitivity reaction type seems to be related to the increase of IL-10.

An unusual dual hypersensitivity reaction to moxifloxacin in a patient

Both immediate and nonimmediate type hypersensitivity reactions (HRs) with a single dose of quinolone in the same patient have not been previously reported. A 47-year-old female patient referred to us because of the history of a nonimmediate type HR to radio contrast agent and immediate type HR to clarithromycin. She experienced anaphylaxis in minutes after the second dose of 50 mg when she was provocated with moxifloxacin. She was treated immediately with epinephrine, fluid replacement and methylprednisole and pheniramine. On the following day she came with macular eruptions, and she was treated with methylprednisolone. The positive patch test performed with moxifloxacin as well as the lymphocyte transformation test proved the T-cell mediated HR. In order to prove the immediate type HR, basophil activation test was performed but was found negative. This case report presents for the first time the 2 different types of HRs in a patient with a test dose of quinolone.

Effectiveness of prophylactic cervical cerclage in prolonging higher-order multiple pregnancies

Objectives: This study aimed to assess the value of prophylactic cervical cerclage in prolonging higherorder multiple pregnancies

Methods: This retrospective study included all women with higher-order multiple pregnancies beyond 24 gestational weeks treated at the King Abdullah University Hospital in Irbid, Jordan, and King Fahad Medical City in Riyadh, Saudi Arabia, between February 2014 and January 2015. Selected maternal characteristics and obstetric outcomes were compared between women who received prophylactic cervical cerclage and those who did not

Results: A total of 146 women with higher-order multiple pregnancies were included in the study; of these, 94 [64.4%] underwent a prophylactic cervical cerclage insertion procedure and 52 [35.6%] women did not. No significant difference was found between the two groups with regards to maternal age, parity or number of fetuses. However, the mean gestational age at delivery was significantly higher for women without compared to those with prophylactic cervical cerclage [32.9 weeks versus 31.7 weeks] according to both univariate and multivariate analyses [P = 0.013 and 0.046, respectively]. Additionally, 40.4% of women without and 14.9% of women with prophylactic cervical cerclage gave birth after 34 gestational weeks [P = 0.003]

Conclusion: Overall, prophylactic cervical cerclage was not associated with prolongation of the pregnancy among women with higherorder multiple pregnancies in the current study

Serum total oxidant/anti-oxidant status, ischemia-modified albumin and oxidized-low density lipoprotein levels in patients with vitamin D deficiency

Objective Oxidative damage may be responsible for the pathogenesis and complications of many diseases. Vitamin D deficiency has been suggested as a potential mediator of various extra-skeletal pathologies. However, there are limited data on anti-oxidant properties of vitamin D.Materials and methods Forty-one subjects with vitamin D deficiency and 30 healthy controls were enrolled into the study. The levels of total anti-oxidant status (TAS), total oxidant status (TOS), ischemia-modified albumin (IMA), oxidized-low density lipoprotein (ox-LDL), high-sensitivity C-reactive protein (hs-CRP) and fibrinogen were measured in both groups. The measurements were repeated in 17 patients after the replacement of vitamin D.Results Serum IMA and TOS levels were significantly higher (p < 0.001 and p = 0.035, respectively), while TAS levels were significantly lower in patients, compared to controls (p < 0.001). Additionally, fibrinogen was significantly higher in patients than controls (p = 0.003), while ox-LDL and hs-CRP levels were similar between two groups. After the replacement of vitamin D, TAS level significantly increased (p = 0.037), and TOS and fibrinogen levels significantly decreased (p = 0.043 and p = 0.010, respectively). Vitamin D levels were negatively correlated with IMA and fibrinogen levels (r = -0.500, p < 0.001 and r = -0.391, p = 0.002, respectively), although positively correlated with TAS levels (r = 0.430, p < 0.001). No correlation was found between vitamin D levels, and the TOS, ox-LDL and hs-CRP levels.Conclusions In this study, while serum IMA, TOS and fibrinogen levels were increased, TAS levels were seen to be decreased in patients with vitamin D deficiency. These results suggest that oxidative/anti-oxidative balance shifts in favours of oxidative status in vitamin D deficiency.

Analysis of primary intrathoracic extrapulmonary hydatid cysts a rare clinical entity

To evaluate the anatomic location of cysts, operative characteristics of intrathoracic extrapulmonary hydatid cyst and to determine the outcome of aggressive surgical interventions.Case series. Thoracic Surgery Unit Lady Reading Hospital Peshawar from 1[st] July 2008 to 30[th] June 2011. All patients admitted to Thoracic unit from July 2008 to June 2011 with intra thoracic hydatid cysts were evaluated prospectively as to age, sex, symptoms, diagnostic procedures, anatomic location of cysts, surgical procedures, complications, and outcomes. Chest radiography, computed tomography, and thoracic and abdominal ultrasonography had been performed preoperatively in all of them. Bronchoscopy and spirometry was also performed in all patients for assessment and operability.Echocardiography had been used in 2 patients to determine the contiguity of the cyst to the pericardium. Cystectomy and wide resection were the chief operative procedures. Most of the patients were having cysts in the pulmonary parenchyma only 10 patients had intrathoracic cysts in extrapulmonary locations. This group of patients was included in the study. We excluded patients who had a parenchymal cyst that had perforated to the pleura, myocardial hydatid and patients who had Total of 149 patients were operated for hydatid cystectomy, out of these 139 patients had pulmonary hydatid and 10 patients had intrathoracic extrapulmonary hydatid cysts. These 10 patients constitute our study group; out of these 7 were men and 3 women whose mean age was 39.14 +/- 16.8 years range, [16-69 years]. Eight [80%] of these were symptomatic, most commonly with chest pain, two patients were asymptomatic. There were 2 [20%] mediastinal hydatid, 2 [20%] diaphragmatic, 2 [20%] pericardial, 2 [20%] oblique fissure, and 1 [10%] each in chest wall and pleural hydatid in our study. Albendazole [10 mg/kg] was prescribed to all patients for as long as 3 months postoperatively. No complication, recurrence, or death occurred during the follow up period of 13 +/- 15.4 months [range, 2-36 months].The extrapulmonary location of Hydatid cysts within the thorax is very rare. This rarity may cause difficulties in diagnosis. To avoid recurrence, it is necessary to resect the affected tissues completely and an anthelmintic medical regimen post operatively
