METHODS A systematic literature search was performed using PubMed, supplemented with additional references. Studies assessing the association of IBD or bariatric surgery with renal stones in both paediatric and adulthood were included. RESULTS Certain types of stones are seen more frequently with IBD. Hyperoxaluria and hypocitraturia are the main metabolic changes responsible for urolithiasis. The incidence of renal stones in malabsorptive types of bariatric surgery such as gastric bypass is high; this is not as common in modern restrictive surgical methods. Preventative methods and urine alkalinisation have been shown to be beneficial.CONCLUSION Both conditions are associated with renal stones. Patients' counselling and prevention strategies are the mainstay of urolithiasis management in these patients.展开更多

The results revealed that the adsorption of the dye on TiO2 is a physical adsorption in accordance with Langmuir isotherm, with a constant of adsorption KL ： 0.52 mg/L and a maximum adsorption capacity b = 18.1 mg/g. The temperature variation of the reaction medium made it possible to consider thermodynamic parameters. Indeed, the adsorption is exothermic （enthalpy： △H 〈 0）, and spontaneous （free enthalpy： △G 〈 0）. The negative entropy （△S 〈 0） confirms the affinity of the dye molecules for TiO2. 20 min of CGAD treatment in the pres- ence of an optimal quantity of TiO2 （2 g/L enabled us to bleach the solution of AO7 （100 μM） completely. The discoloration rate with and without the addition of TiO2 was 100% and 28%, respectively. 40 additional minutes of treatment allowed a total abatement of the chemical oxy- gen demand. The elimination of AO7 molecules during the plasma-catalytic treatment follows Langmuir-Hinshelwood （L-H） model kinetics. According to this model, the speed constant is kr = 14.97 mg-L-1 ·min-1 and the adsorption coefficient is KL-H= 0.010 L/mg. The latter being negligible compared to kr, adsorption is therefore weakly performed during the plasma treatment.展开更多

Primary menopause symptoms in Westem countries included hot flashes, insomnia, somatic pain, depression, and fatigue. Hot flashes were most commonly treated. Menopausal hormone replacement therapy （HRT） continues to have a clinical role in the management of vasomotor symptoms, but since 2002 there has been a marked global decline in its use due to concerns about the risks and benefits of HRT; consequently many women with menopause symptoms are now seeking alternatives including acupuncture. Acupuncture has a long tradition of use for the treatment of different menopause symptoms. Its effectiveness has been studied for natural menopause or chemical and surgery induced menopause. Here we provide an update on recent advances in the field for clinicians. The recent systematic reviews on acupuncture in menopausal symptoms suggest that acupuncture is aneffective and valuable option for women suffering from menopause. However, the science of acupuncture therapies is still inadequate to sufficiently support the benefits of acupuncture therapies. Finally, we discuss our points of view on clinical trials of acupuncture for menopause symptoms.展开更多
