Abstract
The number of patients with drug-resistant tuberculosis (DR-TB) is increasing worldwide. This review summarises the global epidemiology of DR-TB and current treatment challenges. Luckily, novel regimens comprising bedaquiline, pretomanid, linezolid, and moxifloxacin have seemingly mitigated the global threat posed by DR-TB. However, emerging resistance against bedaquiline and pretomanid, among other factors, persists as ongoing concerns in the global fight against DR-TB. While the new regimens are groundbreaking, the sustained development of novel drugs targeting the most resistant forms of tuberculosis is of utmost importance for future efforts against DR-TB.

Abstract
OBJECTIVES To describe demographics, clinical features, and treatment outcomes of patients with highly drug-resistant tuberculosis (TB) in Ukraine, and to evaluate risk factors for an unsuccessful outcome. METHODS Data from patients with multi-, pre-extensively, or extensively drug-resistant TB were collected prospectively from TB dispensaries in 15 out of 24 Ukrainian oblasts (regions) from 2020 to 2021. Treatment outcomes were evaluated using WHO definitions. Risk factors for an unsuccessful outcome were identified using a multivariable logistic regression model. RESULTS Among 1748 patients, the overall proportion of successful outcomes was 58% (95% confidence interval [95% CI] 56-60) (n = 1015/1748), ranging from 65% (95% CI: 62-69) (n = 531/814) for multidrug-resistant TB to 54% (95% CI: 49-58) (n = 301/563) for pre-extensively drug-resistant TB and 49% (95% CI: 44-55) (n = 183/371) for extensively drug-resistant TB. Results were similar across oblasts, with few exceptions. The strongest risk factors for an unsuccessful outcome were extensively drug-resistant TB (adjusted OR [aOR] 3.23; 95% CI: 1.88-5.53), total serum protein below 62 g/L in adults and below 57 g/L for children and adolescents (aOR 2.79; 95% CI: 1.93-4.04), psychiatric illness (aOR 2.79; 95% CI: 1.46-5.33), age at TB diagnosis >65 years (aOR 2.50; 95% CI: 1.42-4.42), and alcohol misuse (aOR 2.48; 95% CI: 1.89-3.26). DISCUSSION The overall proportion of successful outcomes among Ukrainians treated for highly drug-resistant TB was 58%, notably better compared with previous years, but still low for extensively drug-resistant TB. Risk factors for unsuccessful outcomes highlight that addressing socioeconomic factors in TB management is crucial. Efforts in maintaining TB dispensaries during and following the ongoing war are highly warranted.

Abstract
INTRODUCTION Historically, extensively drug-resistant tuberculosis has been notoriously difficult to treat with devasting outcomes. As we are coming to the end of an era where the 2006 extensively drug-resistant tuberculosis definitions and old treatment regimens are being replaced, we aimed to estimate the proportion of extensively drug-resistant tuberculosis patients globally who achieved successful treatment outcomes. METHODS We conducted a systematic review of PubMed/MEDLINE, Scopus, Web of Science, and Embase from January 1, 2005, through April 3, 2023. Included studies reported WHO treatment outcomes, or adaptions hereof, for pre-extensively and/or extensively drug-resistant tuberculosis patients according to the 2006 WHO definition. Eligible studies included cohorts of at least 10 adults (aged>18 years) that were not pregnant. Using a random-effects model, we calculated pooled proportions of treatment outcomes and performed sensitivity and subgroup analyses. PROSPERO registration number: CRD42022340961. RESULTS Among 5056 studies reviewed, we identified 94 studies from 26 countries, involving 10,223 extensively drug-resistant tuberculosis patients. The pooled proportion of successful treatment outcomes was 44.2% (95%CI: 38.3-50.3). Sensitivity analyses consistently produced similar estimates. A slight improvement in treatment outcomes was observed after 2013. Furthermore, 25 studies reported outcomes for 3564 individuals with pre-extensively drug-resistant tuberculosis, of which 63.3% achieved successful treatment (95%CI: 43.1-72.5). CONCLUSION Globally, the success rate of extensively drug-resistant tuberculosis treatment is 44.2%, far below the WHO's target rate of 75%. These results may serve as a reference for future studies assessing extensively drug-resistant tuberculosis treatment outcomes under the 2021 definition treated with better treatment regimens available. Comprehensive surveillance data of extensively drug-resistant tuberculosis outcomes from the whole world are desirable to monitor treatment progress.

Abstract
Non-nucleoside reverse transcriptase inhibitors (NNRTIs) are promising drugs for the treatment of HIV when used in combination with other anti-HIV drugs such as nucleoside reverse transcriptase (RT) inhibitors and protease inhibitors. The first generation of NNRTIs have, however, suffered from the rapid development of resistance. This review discusses the properties of the FDA-approved NNRTI drugs and focuses on the recent efforts being made to produce second generation inhibitors that circumvent this resistance problem.

Abstract
Oxytocin (OT), lysine vasopressin (L8VP), arginine vasopressin (A8VP) or arginine vasotocin (A8VT) are found in plasma from several species and stimulate various cell types by activation of the polyphosphoinositide metabolism and mobilization of intracellular calcium. We therefore studied the effects of the nonapeptides OT, A8VT, L8VP or A8VP on cytoplasmic calcium (Ca2+) and the effect of the nonapeptides on A8VP-induced Ca2+ mobilization. The preincubation of platelets with 'physiological' concentrations of A8VP (2-4 pmol l-1) did not enhance the intracellular calcium increase caused by the agonists used. However, the ADP-induced calcium increase was enhanced by prior addition of subthreshold concentrations of A8VP (less than 1 nmol l-1) to the platelet suspension (by 10%, P = 0.027, n = 12). Neither OT nor A8VT in concentrations from 10(-5) mumol l-1 to 1 mumol l-1 increased the cytoplasmic calcium concentration. We found that both OT and A8VT blocked the effect of subsequent exposure to A8VP. ADP (0.4 mumol l-1) did not block the effect of A8VP.

Abstract
We have isolated a tripeptide from normal plasma and autistic urines which stimulates the uptake of serotonin (5-HT) into platelets. This peptide was purified by high-performance liquid chromatography (HPLC) and characterized by sequenation and mass-spectrometry. Synthetic peptide showed co-chromatography with the biological sample in the HPLC systems used. Close to 60% of the autistic children diagnosed using the Diagnostic Statistical Manual III-R had an increased HPLC peak eluting like this peptide in their urines compared with controls.

Abstract
Seasonal changes in cell physiology are well known. Fluctuations of mood in humans are reflected in the serotonin metabolism in platelets. The mechanisms involved remain unknown. Over four years we have studied the increase in levels of platelet calcium caused by minimal doses of the agonists adenosine 5' diphosphate (ADP) and arginine vasopressin (A8VP) using the calcium-selective fluorescent probe fura-2. We found that in blood platelets from healthy people the basal level of calcium, the amount of calcium mobilized to the cytoplasm and, for vasopressin, the rate of calcium rise, varied periodically and sufficiently to be statistically significant.

Abstract
A novel self-injector for the administration of subcutaneous sumatriptan in the treatment of migraine attacks was tested in 138 patients recruited by family physicians in Denmark: 108 patients completed the initial double-blind, crossover part of the study. Sumatriptan 6 mg s.c. was significantly better than placebo at 30, 60, 90 and 120 min after injection in relieving moderate or severe headache to mild or none as well as relieving any headache to none. At 60 min after injection, the treatment response rate was 61% for sumatriptan and 6% for placebo. During the following open-phase trial of four attacks treated with sumatriptan, treatment response rates were 68-74%. During the total of 538 attacks treated, 12 attempts at using the self-injector failed. In the double-blind and open phases, 81% and 90% of patients respectively found the device easy or very easy to use. Adverse effects were benign and short-lasting, but led seven patients to discontinue the study. In conclusion, subcutaneous sumatriptan administered with a novel self-injector is an effective treatment for migraine compared to placebo in patients treated by their family physician.

Abstract
By focusing the consequences of loading platelets with the fluorescent calcium indicator, fura-2, in buffer or plasma the influences of plasma constituents on calcium responses in blood platelets has been worked out. Proteins were removed from the pre-incubation medium before agonist stimulation and measurement of intracellular calcium concentration [Ca2+]i. We found that moderate amounts (1-33%, v/v) of plasma added to the buffer during pre-incubation stimulated the mobilization of cytoplasmic calcium, delta[Ca2+]i, and reduced the time from agonist stimulation to peak level of [Ca2+]i in platelets stimulated with ADP or arginine vasopressin A8VP. With the buffer used, calcium response was restored by addition of 33% (v/v) plasma to the same level as found for unwashed platelets in the platelet rich plasma (cf. methods). The presence of human serum albumin during the pre-incubation also influenced the calcium response, but not to the same extent as plasma. From a resting level of 73 +/- 10 nmol l-1, addition of 0.4 mumol l-1 ADP increased the [Ca2+]i by 24 +/- 13 nmol l-1 (n = 20), 65 +/- 30 nmol l-1 (n = 5), and 144 +/- 44 nmol l-1 (n = 22) in platelets pre-incubated with buffer, 5 gl-1 albumin, and 33% (v/v) plasma, respectively. The corresponding values after stimulation with 0.05 mumol l-1 A8VP were 49 +/- 34 nmol l-1, 105 +/- 27 nmol l-1, and 170 +/- 39 nmol l-1, (n = 7). In platelets incubated in buffer only, the delta t from stimulation with 0.4 mumol l-1 ADP was 18.9s.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Blood platelets from women showed increased sensitivity to adenosine diphosphate (ADP) during ovulation compared with menstruation. The increased sensitivity was registered as an increase in cytoplasmic calcium response measured with the fluorescent indicator fura-2. Agonist dose-response studies revealed an increased maximal response, but the dose that gave half maximal response was unchanged. This indicates an increased mobility of calcium, without changed affinity to receptor(s).

Abstract
The problems in the evaluation of children with suspected infravesical obstruction are shortly reviewed. Based upon literature studies it is concluded, that an isolated urinary flow measurement determining the Qmax is a suitable procedure of screening. Due to different shortcomings of earlier published normal materials, we investigated the spontaneous urination of 205 normal children aged 3 to 13 years in their normal environment. The mictiograph was installed in the toilet of two kindergartens and one school, enabling the children freely to void into the machine upon desire. From the flow curves the following parameters were calculated: Q1 sec, Qmax, Qmax time, and the micturition time, all of them being related to the square root of the voided volume. The data were non-parametrically statistically processed, and the limits of normal values (2 1/2% and 97 1/2% percentiles) are defined for different groups of age and sex. Furthermore, the different flow curve patterns are described, and it is found, that in 90% of the cases they are identical to the adult pattern.
