There are currently various fixation or suspension techniques for pelvic organ prolapse (POP) surgery. Laparoscopic colposacropexy is considered the gold standard. We present the surgical steps of the laparoscopic latero-abdominal colposuspension (LACS) technique and the preliminary results obtained.

Patients with anterior and/or apical compartment symptomatic POP undergoing LACS are included. The Baden-Walker scale, the Overactive Bladder Questionnaire-Short Form (OAB-q SF), the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) and the Patient Global Impression of Improvement (PGI-I) scale were used to assess the degree of prolapse, urinary filling and sexual symptoms and the level of satisfaction before and after surgery, respectively. Conventional laparoscopic material and a polyvinylidene fluoride (PVDF) mesh were used.

Eighteen patients were included with a minimum follow-up time of 6months. The mean surgical time was 70.3±23.8min. Anatomic correction of prolapse was seen in all cases. Only one recurrence was detected. High levels of patient satisfaction were achieved.

LACS allowed the anatomical reconstruction of the pelvic floor and proved to be a minimally invasive, fast, effective, safe and reproducible technique. More series are needed to evaluate its role against laparoscopic colposacropexy.

MEK inhibitor The aim of this study was to survey national measures to manage and combat these shortages. A questionnaire survey was conducted with public authorities involved in the Pharmaceutical Pricing and Reimbursement Information (PPRI) network. Reponses relating to measures as of March / April 2020 were received from 24 countries (22 European countries, Canada and Israel). In 20 countries, manufacturers are requested to notify - usually on an obligatory basis - upcoming and existing shortages, which are recorded in a register. Further measures include a regular dialogue with relevant stakeholders (18 countries), financial sanctions for manufacturers in cases of non-supply and/or non-compliance with reporting or stocking requirements (15 countries) and simplified regulatory procedures (20 countries). For defined medicines, supply reserves have been established (14 countries), and legal provisions allow the issuing of export bans (10 countries). Some measures have been introduced since the end of 2019 and countries are planning and discussing further action. While governments reacted by taking national measures, the COVID-19 crisis might serve as an opportunity to join forces in cross-country collaboration and develop joint (e.g. European) solutions to address the shortage issue in a sustainable manner. A practical first step could be to work on a harmonisation of the national registers.
Rotavirus remains the commonest cause of dehydrating diarrhoea, particularly in developing countries. Human infection challenge studies in children in these countries offers an opportunity to rapidly evaluate new vaccine candidates that may have improved efficacy. We evaluated use of Rotarix™ as a live-attenuated challenge agent.

We undertook an open label, exploratory study in infants receiving two standard doses of Rotarix™ at 6 and 10 weeks of age in a cohort of 22 Zambian infants. The first vaccine dose was considered as primary vaccination, and the second at day 28 as a live-attenuated virus challenge. Saliva, stool and serum samples were collected on days 0, 3, 5, 7, 14, and 28 following each dose. The primary outcome was stool shedding of rotavirus, determined by NSP2 qPCR. We calculated mean shedding index as average of natural logarithm of viral copies per gram of stool.

After the first dose, viral shedding was high at day 3, peaked by day 5. After the second dose, viral shedding at day 3 was low and reduced gradually in most infants until day 14. Mean shedding index was significantly lower post dose 2 across all infants and timepoints (5.0 virus copies/g of stool [95%CI 0.3-9.7] vs 10.4 virus copies/g of stool [95%CI 6.2-14.6]; p-value < 0.0001; rho = 0.20, SD = 4.97. Seroconversion at day 28 was associated with a mean reduction of -1.03 (95%CI = -8.07, 6.01) in viral shedding after challenge dose but this was not statistically significant (p = 0.774). A borderline positive correlation between fold-change in IgA titre at day 28 from day 0 in saliva and serum was observed; Spearman's correlation coefficient, r = 0.69; p = 0.086.

Shedding after the 'challenge' dose was reduced compared with the first dose, consistent with the induction of mucosal immunity by the first dose. This supports the use of Rotarix vaccine as a live-attenuated infection challenge.

This systematic review and meta-analysis assesses the pharmacokinetic (PK) summary estimates of isoniazid (INH) between healthy volunteers and patients with tuberculosis (TB), evaluates whether the current INH dose regimen is appropriate in patients with TB, and evaluates the impact of N-acetyl-transferase-2 (NAT2) status on the PK properties of INH.

A systematic approach was conducted to find studies with relevant INH PK data published in the English language up to February 2018. The PK properties of INH were extracted with their respective INH dosages and were dose normalized to allow a fair comparison between healthy volunteers and patients with TB. Meta-analysis was then performed for the C
and AUC estimates for all INH dosages.

Ninety studies were included in this systematic review. TB status significantly affected the INH C
and AUC estimates. In healthy volunteers, the dose-normalized INH C
and AUC were statistically higher than those of patients with TB. No significant differences were founence, testing for acetylator status is highly recommended, and therapeutic drug monitoring would help reduce INH toxicity.
