Multidrug-resistant tuberculosis (MDR-TB) is increasing among migrants in Canada. To what extent this increase is attributable to local transmission, recent immigration, or changed proportion of MDR-TB in immigrants' country of birth, is unknown.

We performed a retrospective cohort study in a Canadian province with substantially increased immigration between 1982-2001 and 2002-2019. The proportion of MDR-TB among migrants arriving from high MDR-TB burden (HMDR-TB) countries during these two periods was used to estimate the proportion of cases due to immigration versus change in proportion in country of birth. Epidemiologic, spatio-temporal, and drug resistance pattern data were used to confirm local transmission.

Fifty-two of 3,514 (1.48%) foreign-born culture-positive TB patients had MDR-TB; 8 (0.6%) in 1982-2001, 44 (2.0%) in 2002-2019. Between time periods, the proportion of MDR-TB among migrants with TB from HMDR-TB countries increased from 1.11% to 3.62%, p=0.003; 31.6% attributable to recent immigration, 68.4% to a higher proportion of MDR-TB in cases arrived from HMDR-TB countries. No cases of MDR-TB were attributable to local transmission.

In stark contrast to HMDR-TB countries, local transmission plays no important role in the occurrence of MDR-TB in Canada. Overseas investments to improve TB programming in HMDR-TB countries are urgently needed.

The treatment success rate of drug-resistant tuberculosis (DR-TB) is alarmingly low. Therefore, more effective and less complex regimens are urgently required.

We compared the efficacy of an all oral DR-TB drug regimen consisting of bedaquiline (25mg/kg), delamanid (2.5mg/kg) and linezolid (100mg/kg) (BDL) on the mycobacterial load in the lungs and spleen of TB infected mice during a treatment period of 24 weeks. This treatment was compared to the standard regimen of isoniazid, rifampicin, pyrazinamide and ethambutol (HRZE). Relapse was assessed 12 weeks post-treatment. Two logistic regression models were developed to compare the efficacy of both regimens.

Culture negativity in the lungs was achieved at 8 and 20 weeks of treatment with BDL and HRZE, respectively. After 14 weeks of treatment only one mouse relapsed in the BDL group, while in the HRZE group relapse was still observed at 24 weeks of treatment. Predictions from the final mathematical models showed that a 95% cure rate was reached after 20.5 and 28.5 weeks of treatment with BDL and HRZE, respectively.

The BDL regimen was observed to be more effective than HRZE and could be a valuable option for the treatment of DR-TB.

To assess the impact of Florida's 3-day opioid prescription supply law, effective July 2018, on opioids dispensed for acute pain patients.

Pharmacy claims from a health plan serving a large Florida employer from January 2015 through March 2019 were analyzed. We used an interrupted time series study design accounting for autocorrelation of trends before and after policy change. Acute pain patients met inclusion criteria if they had not received any opioid containing medications in the past 180 days. Patients could contribute to additional new use time if subsequent opioid claims occurred ≥180 days since the previous claim. Outcomes included mean number of units dispensed of the initial opioid prescription, mean morphine milligram equivalents (MMEs) per day of initial prescription by month, and mean total MMEs per initial prescription by month.

A total of 8,375 enrollees had 10,583 unique opioid starts in the given timeframe. Following the policy, there was an immediate significant decrease in the units dispensed per prescription of 4.9 (95% CI -8.95, -0.82 units). this website Additionally, there was a significant immediate reduction in total MMEs dispensed per prescription of 25.6 (95% CI -44.76, -6.44 MMEs).

Among a group of privately-insured plan enrollees in Florida, and as a result of the law, there were significant decreases in the number of units dispensed, and total MMEs of opioid prescriptions. The immediate reduction in new opioid utilization following policy implementation suggests effective policy; however, impacts on chronic pain patients were not assessed.

Breast cancer (BC) is a leading cause of morbidity, mortality, and disability for women, worldwide. There is substantial variation in treatment outcomes, which is function of multiple variables, including access to treatment. Treatment standards can promote quality and improve survival; thus, their development should be a priority for the cancer control planning.

We extracted the guidelines for the treatment of BC from a systematic review of the literature. We evaluated the development process, the methodology and the recommendations formulated, and surveyed the country resource stratification. Metrics of health system capacity were selected, to study the guidelines context- appropriateness.

We analysed 49 distinct guidelines for BC, mostly in English language (n = 23), developed in upper-middle and high-income countries of the European and American Regions (n = 39). A resource-stratified approach was identified in a quarter of the guidelines (n = 11), mostly from resource- constrained settings. Only a half of the guidelines reached a gender balance of the authorship and 10.2% were based on a multidisciplinary steering committee. A number of efforts and solutions of resource adaptations were recognized, mostly in low- and middle-income countries. Overall, the national guidelines appeared not enough sensitive of the local health system capacity in formulating recommendations, with possible exception for the radiation therapy availability.

This global landscape of treatment standards for BC demonstrates that the majority are not context appropriate. Research on the formulation of cancer treatment standards is highly warranted, along with novel platforms for developing and disseminating resource-appropriate guidance.
