    Abstract: Although ketamine has become the second most popular recreational drug in Taiwan, there have been very few reported studies that investigated female sexual dysfunction (FSD) in ketamine abusers (KAs). Aims We sought to compare the difference between street and hospital KAs and explored the risk factors for FSD and lower urinary tract symptoms (LUTS) in KAs. Methods In this cross-sectional study, female KAs aged 18 years or older were invited to complete anonymous questionnaires during an educational course provided by the departments of substance control and prevention of the local government or under the instruction of medical providers at a urology clinic. Data were reported as median (IQR) and OR and analyzed with commercial statistical software. Outcomes Key outcome measurements were illicit drug use history, FSD symptoms, and LUTS severity. Results We included 139 women (104 street and 35 hospital KAs) with a median age of 27.08 years. FSD was reported in 76% of all the participants (street vs hospital KAs, 68% vs 97%, P  & lt; 0.001). LUTS (Interstitial Cystitis Symptom Index [ICSI] + Interstitial Cystitis Problem Index [ICPI] ≥12) was found to be a significant risk factor for FSD in KAs. More hospital KAs (71%) reported experiencing LUTS (ICSI + ICPI ≥12) than street KAs (8%, P  & lt; 0.001). Longer duration of ketamine use (≥36 months) and mild to severe psychological symptoms (5-item Brief Symptom Rating Scale [BSRS-5] ≥6) were significant risk factors for LUTS. Clinical Implications Sexual problems among KAs should not be overlooked since more severe sexual dysfunction was observed in patients reporting LUTS. Strengths and Limitations To our knowledge, the present study is the largest study using validated and reliable questionnaires to examine FSD in KAs and also the first study to include street KAs. The main limitation of this study is using self-report questionnaires as they are subjective and susceptible to human errors and recall biases. Conclusions Women who abused ketamine and reported experiencing LUTS were found to be more likely to have FSD.

    Abstract: Our previous study identified that the Mycobacterium abscessus subsp. abscessus T28 sequevar does not fully represent inducible macrolide resistance. Thus, we initiated a correlation study between genotypes and phenotypes. In total, 75 isolates from patients with skin and soft tissue infections were enrolled in the study. These strains were tested against 11 antimycobacterial agents using Sensitire RAPMYCO plates and the CLSI-recommended broth microdilution method. In order to analyze erm (41) and partial hsp65 , rpoB , secA1 , and rrl genes, bacterial genomic DNA was extracted from bacteria. The MEGA X software was used for phylogenetic analyses. The most active agents against most M. abscessus species were amikacin and tigecycline. Clarithromycin was effective toward M. abscessus subsp. massiliense and nearly all M. abscessus subsp. abscessus C28 sequevars. Two varieties of M. abscessus subsp. abscessus T28 sequevars did not represent inducible macrolide resistance. Most M. abscessus species showed intermediate susceptibility to cefoxitin and imipenem. Six additional agents were less effective against M. abscessus species. Following phylogenetic analyses, two outliers of M. abscessus subsp. abscessus T28 sequevars seem to represent no inducible macrolide resistance. In addition, we discovered genetic mosaicism of hsp65 , rpoB , and secA1 in M. abscessus species was common. T28 sequevars of M. abscessus subsp. abscessus do not fully represent inducible macrolide resistance. The outlier of erm (41) phylogeny of the M. abscessus subsp. abscessus T28 sequevar is possibly due to macrolide susceptibility. Evaluation of the antimicrobial susceptibility of M. abscessus species is a reliable tool for assisting physicians in selecting the most effective antimycobacterial agent(s). IMPORTANCE Macrolides are the mainstays of the antimycobacterial regimens against Mycobacterium abscessus species (formerly Mycobacterium abscessus complex). erm (41) confers inducible macrolide resistance for M. abscessus subsp. bolletii strains, and the majority of M. abscessus subsp. abscessus T28 sequevars. Furthermore, the acquired macrolide resistance of M. abscessus species is due to a point mutation in rrl . However, not all M. abscessus subsp. abscessus T28 sequevars have inducible macrolide resistance. Exploration of the mechanism of macrolide resistance requires an understanding of genetic diversity. The genetic mosaicism of the erm (41), rpoB , hsp65 , and secA1 genes within three subspecies of M. abscessus species is not uncommon. The T28 sequevar of erm (41) confers inducible macrolide resistance to the genetic mosaic strain. The development of new anti- M. abscessus species infection overcoming inducible macrolide resistance and/or acquired macrolide resistance is a crucial issue.
