A novel, selective and sensitive method is developed for simultaneous estimation of canagliflozin and metformin and successfully applied to fast and fed pharmacokinetic studies in healthy Indian volunteers. The current study reports the development, optimization, and validation of liquid chromatography-mass spectrometry (LC-MS/MS) method for simultaneous quantification of canagliflozin and metformin in human plasma using deuterated canagliflozin D4 and metformin D6 as an internal standard (IS). The solid-phase extraction technique was employed where strata X polymeric reverse phase (30 mg-1 cc) SPE cartridges were used for the extraction of analytes and IS from plasma. The ACE 5 C18 column (50 × 4.6 mm, 5µ) was used to chromatograph the prepared samples. The mobile phase consisted of methanol and 5 mM ammonium trifluoroacetate in water, pH 5 (5050, v/v) at a flow rate of 0.8 mL/min. Detection was performed by positive ion Turbo ion spray in Multiple reaction monitoring (MRM) mode, monitoring the transitions m/z 461.9 → m/z 191.1 and m/z 461.9 → m/z 267.2, for quantification of canagliflozin. The response of canagliflozin fragments m/z 461.9 → m/z 191.1 and m/z 461.9 → m/z 267.2 was combined. Also, for metformin transitions were monitored at m/z 130.0 → m/z 71.1.

Linearity was in the range of 24.95-2806.55 ng/mL for canagliflozin and 24.99-3400.72 ng/mL for metformin. The mean extraction recovery of canagliflozin, canagliflozin D4, metformin, and metformin D6 was 77.240, 84.663, 66.747, and 67.449, respectively across four QC levels. This rapid method with the run time of 2.80 min allows the analysis of more than 400 plasma samples per day.We encourage studies on the effectiveness of multiple sclerosis drugs for the treatment of ARDS in COVID-19 infection. These drugs, through the inhibition of the RhoA/actin-dependent expression of virus receptors in the macrophages and macrophage recruitment to the lungs, have the potential to inhibit cytokine storm of lung macrophages, reduce or eliminate ARDS and improve the outcome of COVID-19 infection.<br /><br /> Urinary tract infections (UTIs) are one of the commonest reasons for patients with multiple sclerosis (PwMS) presenting to hospital. Management of recurrent UTIs in PwMS can be challenging and characteristics of such patients are not well described.<br /><br /> To describe the neurological and urological features of PwMS presenting to hospital for UTIs and identify areas of management that could be improved to reduce UTI frequency.<br /><br /> Health episode statistics data were used to identify PwMS presenting to a tertiary hospital with UTI over a 5-year period. Medical records were reviewed for demographic, MS and urological history. The seven PwMS with the highest numbers of encounters were seen in a multidisciplinary clinic to enable detailed assessments.<br /><br /> 52 PwMS (25 female, 27 male) with mean age of 60 had 112 emergency department presentations and 102 inpatient admissions for UTI. 24 presented multiple times and were more likely to be older and male with progressive MS. Almost two-thirds were using a urinary catheter. Less than half were under current urological and neurological follow-up. Escherichia coli and Pseudomonas spp were the commonest organisms cultured. Resistance to antibiotics was more frequent in patients with multiple presentations.<br /><br /> PwMS presenting to hospital for UTIs are more often male, older, with progressive MS and high levels of disability. A small group of PwMS accounted for a large number of encounters. Preventative and management strategies can be applied in primary and secondary care settings, with an emphasis on bladder, catheter and general physical care.<br /><br />PwMS presenting to hospital for UTIs are more often male, older, with progressive MS and high levels of disability.

Consequently, management of NMOSD patients in Latin American (LATAM) has become more complex and challenging in clinical practice. In making these consensus recommendations, the aim was to review how the disease should be managed and treated among LATAM patients, in order to improve long-term outcomes in these populations.<br /><br /> A panel of LATAM neurologists who are experts in demyelinating diseases and dedicated to management and care of NMOSD patients gathered virtually during 2019 and 2020 to make consensus recommendations on management and treatment of NMOSD patients in LATAM. To achieve this consensus, the RAND/UCLA methodology for reaching formal consensus was used.<br /><br /> The recommendations focused on diagnosis and differential diagnoses, disease prognosis, tailored treatment, identification of suboptimal treatment response and special circumstances management. They were based on published evidence and expert opinions.<br /><br /> The recommendations of these consensus guidelines seek to optimize management and specific treatment of NMOSD patients in LATAM.<br /><br />The recommendations of these consensus guidelines seek to optimize management and specific treatment of NMOSD patients in LATAM.<br /><br /> The family-caregiver role is of critical importance to the success of symptom-related self-management of patients with advanced cancer. This study examined the perspectives of patients and family-caregivers regarding the role of the family-caregiver in symptom-related self-management support ( SMS).<br /><br /> Semi-structured interviews were conducted in patients with advanced cancer experiencing significant symptom burden and their family-caregivers. An inductive content analysis approach was used to analyse data.<br /><br /> Eleven patients and ten family caregivers were included. Identified themes were 1) engaging in specific symptom-related SMS; 2) interacting with health care professionals; and 3) balancing patient need versus expectation. These themes were applicable to both the family-caregiver and patient cohorts, regardless of the individual symptom profile of each patient.<br /><br /> The role of family-caregivers of patients with advanced cancer is complex and varied in providing symptom-related SMS at home; often requiring family-caregivers to have diverse knowledge and skills in the management of a range of cancer-related symptoms.
