To explore radiologist characteristics and case features associated with diagnostic performances in cancer detection on mammograms in a South East Asian population.
Fifty-three radiologists reported 60 mammographic examinations which consisted of 40 normal and 20 cancer-containing cases at the BREAST workshops. Radiologists were asked to examine each mammogram using the BIRADS on diagnostic monitors. Differences in reader characteristics and case features between correct and incorrect decisions were assessed separately for cancer and normal cases. Univariate and multivariate logistic regressions were applied to generate odds ratios (OR) for significant factors related to correct decisions.
Radiologists who spent ≥10hours/week reporting mammograms had a higher possibility of detecting cancer lesions (OR=1.6; P=0.01). A higher rate of accuracy in reporting negative cases was associated with female radiologists (OR=1.4; P=0.002), radiologists who read ≤20 mammograms per week (OR=1.5; P<0.0001), had compast cancer detectability of radiologists.Several strategies have been successfully utilised to obtain a wide range of interlocked molecules. However, some interlocked compounds are still not obtained directly and/or efficiently from non-interlocked components because the requisites for self-assembly cannot always be enforced. To circumvent such a synthetic problem, a strategy that consists of synthesizing an isolable and storable interlocked building block in a step that precedes its modification is an appealing chemical route to more sophisticated interlocked molecules. Synthetic opportunities and challenges are closely linked to the fact that the mechanical bond might greatly affect the reactivity of a functionality of the encircled axle, but that the interlocked architecture needs to be preserved during the synthesis. Hence, the mechanical bond plays a fundamental role in the strategy employed. This Review focuses on the challenging post-synthetic modifications of interlocked molecules, sometimes through cleavage of the axle's main chain, but always with conservation of the mechanical bond.
The most common extra pulmonary organ dysfunction in acute respiratory distress syndrome is acute kidney injury. Current data so far indicate low incidence of AKI in Covid-19 disease.
In this retrospective study, we analysed the clinical features of patients diagnosed with Covid-19 and investigated the effect of Covid-19 on kidney function.
Ninety-six patients diagnosed with Covid-19 were included in our study. Demographic features (Age, gender, co-morbidities), symptoms, thorax CT findings, Covid-19 PCR results and laboratory findings were recorded. The clinical features of the patients were analysed and kidney function values before Covid-19 diagnosis were compared with kidney function values after Covid-19 diagnosis.
Most presenting symptom was fever (51%). Most accompanying co-morbidity was hypertension (56%). According to laboratory findings; ferritin, D-dimer and C-reactive protein levels were statistically significantly higher in ARDS group than severe pneumonia and pneumonia group (P=.002, P=.001 and P<.001, respectively). Also lymphocyte levels were statistically significantly lower in ARDS group than severe pneumonia and pneumonia group (P=.042). According to KDIGO criteria 3 (3.1%) patients had AKI during the hospital stay. For all patients, there was statistically significant difference between basal, 1st, 5th and 10th day BUN and SCr levels (P=.024 and P=.018, respectively). For severe pneumonia group there was statistically significant difference between basal, 1st, 5th and 10th day SCr levels (P=.045).
Our study demonstrated that Covid-19 can cause renal impairment both with pneumonia and ARDS. A large-scale prospective randomised studies are needed to reach final judgement about this topic.

Markovnikov hydrofunctionalization products are obtained under mild ligand-free conditions, with up to 99 % yield and >201 selectivity. Alternatively, anti-Markovnikov products can be accessed with a novel 4,4-disubstituted Pyrox ligand in excellent yield and >201 selectivity. Both electronic and steric effects on the ligand contribute to the high yield and selectivity. Mechanistic studies suggest a change in the turnover-limiting and selectivity-determining step induced by the optimal ligand. DFT calculations reveal that in the anti-Markovnikov pathway, repulsion between the ligand and the alkyl group is minimized (by virtue of it being 1° versus 2°) in the rate- and regioselectivity-determining transmetalation transition state.
The mechanisms underlying hypertriglyceridemia-induced impaired glucose tolerance in Japanese individuals remain unclear. We aimed to evaluate the effect of hypertriglyceridemia on glucose metabolism in comparison with that of increased low-density lipoprotein or decreased high-density lipoprotein levels and to elucidate the sex differences in hypertriglyceridemia-related dietary intake among Japanese individuals.
We randomly selected 898 (384 men and 514 women) participants aged 40-78years in the Gifu Diabetes Study; those taking medication for dyslipidemia or diabetes mellitus were excluded. Serum levels of glucose metabolism parameters and the food frequency were measured cross-sectionally. The glycated hemoglobin was measured again after 5years.
Glucose metabolism parameters and the percentage of individuals with impaired glucose tolerance were significantly higher in the high triglyceride group in men and women. Similar trends were observed in the low high-density lipoprotein group, but only in menergy intake in non-obese men and increased total energy intake in obese women were associated with hypertriglyceridemia.
