RESUMO
Purpose: Wound swab cultures are frequently requested from patients suspected of having a wound infection. The quality of the sample should also be evaluated by performing a Gram-stained microscopic examination. "Q-scoring system" is not widely used and the literature on the subject is limited. Methods: A total of 4648 wound swab samples were evaluated. Samples with a Q-score of "0" were considered as "poor quality samples", and those with a score of " ≥ 1" were classified as "good quality samples". Microorganisms grown in the culture of samples that scored above one were identified by mass spectrometry, and antimicrobial susceptibility testing was performed. Results: Gram stain results were found to be consistent with the culture result in 57.10% (n = 1078) of and inconsistent with the culture result in 42.90% (n = 813) of the samples. The number of samples with Q-scores one, two, and three among the 813 samples was 62, 29, and 722, respectively. The value observed in Q3 was found to be statistically significantly higher than the values observed in Q1 and Q2 (p < 0.05). Samples sent from surgical departments (61.92%) with a Q-score of ≥ 1, were statistically significant compared to internal medicine departments (p < 0.0001). There was no significant difference between samples sent from intensive care units and those sent from other inpatient services. For both groups with Q-scores ≥ 1 and "0" similar microorganisms were identified. Conclusion: As a conclusion, the Q-scoring system will provide a common language between the laboratory and the clinic, especially by standardizing the evaluation of wound swab samples.
RESUMO
BACKGROUND: Studies on data collection and quality of care in Italian family medicine are lacking. The aim of this study was to assess the completeness of data collection of patients with diabetes in a large sample of family physicians in the province of Verona, Veneto region, a benchmark for the Italian National Health System. METHODS: We extracted the data on all the patients with diabetes from the electronic health records of 270 family physicians in 2006 and 2009. We reported the percentage of patients with data recorded for 12 indicators of performance derived from the National Institute for Clinical Excellence diabetes guidelines. Secondarily, we assessed quality of care using the Q-score (the lower the score, the greater the risk of cardiovascular events). RESULTS: Patients with diabetes were 18,507 in 2006 and 20,744 in 2009, and the percentage of patients registered as having diabetes was 4.9% and 5.4% of the total population, respectively (p < 0.001). Data collection improved for all the indicators between 2006 and 2009 but the performance was still low at the end of the study period: patients with no data recorded were 42% in 2006 and 32% in 2009, while patients with data recorded for ≥5 indicators were 9% in 2006 and 17% in 2009. The Q-score improved (mean ± SD, 20.7 ± 3.0 in 2006 vs 21.3 ± 3.6 in 2009, p < 0.001) but most patients were at increased risk of cardiovascular events in both years (Q-score ≤ 20). CONCLUSIONS: We documented an improvement in data collection and quality of care for patients with diabetes during the study period. Nonetheless, data collection was still unsatisfactory in comparison with international benchmarks in 2009. Structural interventions in the organization of family medicine, which have not been implemented since the study period, should be prioritised in Italy.

BACKGROUND: Aortic dilation (AoD) is commonly reported in patients with bicuspid aortic valve (BAV) and has been related to flow abnormalities and genetic predisposition. AoD-related complications are reported to be extremely rare in children. Conversely, an overestimate of AoD related to body size may lead to excess diagnoses and negatively impact quality of life and an active lifestyle. In the present study, we compared the diagnosis performance of the newly introduced Q-score (based on a machine-learning algorithm) versus the traditional Z-score in a large consecutive pediatric cohort with BAV. MATERIALS AND METHODS: Prevalence and progression of AoD were evaluated in 281 pediatric patients ages > 5 and < 18 years at first observation, 249 of whom had isolated BAV and 32 had BAV associated with aortic coarctation (CoA-BAV). An additional group of 24 pediatric patients with isolated CoA was considered. Measurements were made at the level of the aortic annulus, Valsalva sinuses, sinotubular aorta, and proximal ascending aorta. Both Z-scores using traditional nomograms and the new Q-score were calculated at baseline and at followup (mean 4.5 years). RESULTS: A dilation of the proximal ascending aorta was suggested by traditional nomograms (Z-score > 2) in 31.2% of patients with isolated BAV and 18.5% with CoA-BAV at baseline and in 40.7% and 33.3%, respectively, at followup. No significant dilation was found in patients with isolated CoA. Using the new Q-score calculator, ascending aorta dilation was detected in 15.4% of patients with BAV and 18.5% with CoA-BAV at baseline and in 15.8% and 3.7%, respectively, at followup. AoD was significantly related to the presence and degree of aortic stenosis (AS) but not to aortic regurgitation (AR). No AoD-related complications occurred during the followup. CONCLUSIONS: Our data confirm the presence of ascending aorta dilation in a consistent subgroup of pediatric patients with isolated BAV, with progression during followup, while AoD was less common when CoA was associated with BAV. A positive correlation was found with the prevalence and degree of AS, but not with AR. Finally, the nomograms used may significantly influence the prevalence of AoD, especially in children, with a possible overestimation by traditional nomograms. This concept requires prospective validation in long-term followup.
RESUMO
Background: This study investigated the reconstruction effect of skin-preserving breast cancer modified radical mastectomy combined with one-stage breast prosthesis implantation in female patients to analyze relevant factors and observe the effect of prosthesis reconstruction on short-term breast satisfaction, psycho-social functions, and quality of life (QOL) in patients with breast cancer after the operation. Methods: Patients were divided into two groups based on the reconstruction effect (an excellent effect group and a good and general effect group). Patients' short-term cosmetic effect on the breast after breast cancer modified radical mastectomy combined with one-stage breast prosthesis implantation was prospectively followed up to analyze influencing factors. At post-operative 6 months, the breast satisfaction dimension, psycho-social dimension, upper limb breast health dimension, and surgical satisfaction dimension in the prosthesis reconstruction module in the BREAST-Q scale were used for follow-up evaluation. Results: The excellent rate of prosthesis reconstruction was 91.3%. A significant correlation was observed among the reconstruction effect, implant volume, and number of children born by the patient (P < 0.05). The correlation with age, BMI (body mass index), operation time, nipple and areola retention, operation method, and incision was not statistically significant (P > 0.05). At post-operative 6 months, the Breast-Q score was significantly different in the overall breast satisfaction dimension and outcome satisfaction dimension between the two groups (P < 0.05). Conclusion: Breast cancer modified radical mastectomy combined with one-stage breast prosthesis implantation can not only fulfill patients' physical aesthetic needs but also positively affect their psychosocial behavior to improve post-operative QOL.

As a discipline, structural biology has been transformed by the three-dimensional electron microscopy (3DEM) "Resolution Revolution" made possible by convergence of robust cryo-preservation of vitrified biological materials, sample handling systems, and measurement stages operating a liquid nitrogen temperature, improvements in electron optics that preserve phase information at the atomic level, direct electron detectors (DEDs), high-speed computing with graphics processing units, and rapid advances in data acquisition and processing software. 3DEM structure information (atomic coordinates and related metadata) are archived in the open-access Protein Data Bank (PDB), which currently holds more than 11,000 3DEM structures of proteins and nucleic acids, and their complexes with one another and small-molecule ligands (~ 6% of the archive). Underlying experimental data (3DEM density maps and related metadata) are stored in the Electron Microscopy Data Bank (EMDB), which currently holds more than 21,000 3DEM density maps. After describing the history of the PDB and the Worldwide Protein Data Bank (wwPDB) partnership, which jointly manages both the PDB and EMDB archives, this review examines the origins of the resolution revolution and analyzes its impact on structural biology viewed through the lens of PDB holdings. Six areas of focus exemplifying the impact of 3DEM across the biosciences are discussed in detail (icosahedral viruses, ribosomes, integral membrane proteins, SARS-CoV-2 spike proteins, cryogenic electron tomography, and integrative structure determination combining 3DEM with complementary biophysical measurement techniques), followed by a review of 3DEM structure validation by the wwPDB that underscores the importance of community engagement.
RESUMO
In this controlled before-after study, wound swabs were only processed for culture, identification, and susceptibility testing if a quality metric, determined by the Q score, was met. Rejection of low-quality wound swabs resulted in a modest decrease in reflexive antibiotic initiation while reducing laboratory workload and generating few clinician requests.
RESUMO
Reports act as an important feedback tool in External Quality Assessment (EQA). Their main role is to score laboratories for their performance in an EQA round. The most common scores that apply to quantitative data are Q- and Z-scores. To calculate these scores, EQA providers need to have an assigned value and standard deviation for the sample. Both assigned values and standard deviations can be derived chemically or statistically. When derived statistically, different anomalies against the normal distribution of the data have to be handled. Various procedures for evaluating laboratories are able to handle these anomalies. Formal tests and graphical representation techniques are discussed and suggestions are given to help choosing between the different evaluations techniques. In order to obtain reliable estimates for calculating performance scores, a satisfactory number of data is needed. There is no general agreement about the minimal number that is needed. A solution for very small numbers is proposed by changing the limits of evaluation.Apart from analyte- and sample-specific laboratory evaluation, supplementary information can be obtained by combining results for different analytes and samples. Various techniques are overviewed. It is shown that combining results leads to supplementary information, not only for quantitative, but also for qualitative and semi-quantitative analytes.

The aims of this study were to investigate visual-construction and organizational strategy among individuals with severe obesity, as measured by the Rey Complex Figure Test (RCFT), and to examine the validity of the Q-score as a measure for the quality of performance on the RCFT. Ninety-six non-demented morbidly obese (MO) patients and 100 healthy controls (HC) completed the RCFT. Their performance was calculated by applying the standard scoring criteria. The quality of the copying process was evaluated per the directions of the Q-score scoring system. Results revealed that the MO did not perform significantly lower than the HC on Copy accuracy (mean difference -0.302, CI -1.374 to 0.769, p = 0.579). In contrast, the groups did statistically differ from each other, with MO performing poorer than the HC on the Q-score (mean -1.784, CI -3.237 to -0.331, p = 0.016) and the Unit points (mean -1.409, CI -2.291 to -0.528, p = 0.002), but not on the Order points score (mean -0.351, CI -0.994 to 0.293, p = 0.284). Differences on the Unit score and the Q-score were slightly reduced when adjusting for gender, age, and education. This study presents evidence supporting the presence of inefficiency in visuospatial constructional ability among MO patients. We believe we have found an indication that the Q-score captures a wider range of cognitive processes that are not described by traditional scoring methods. Rather than considering accuracy and placement of the different elements only, the Q-score focuses more on how the subject has approached the task.
RESUMO
BACKGROUND: This study assessed eating disorder pathology in persons with obesity before and after Roux-en-Y gastric bypass (RYGB) and biliopancreatic diversion with duodenal switch (DS), in a 5-year follow-up study. METHODS: Sixty participants with BMI 50-60 kg/m(2) were randomly assigned to RYGB (n = 31) or DS (n = 29). The participants completed the Eating Disorder Examination-Questionnaire (EDE-Q) before and 6 months, 1 year, 2 years, and 5 years after surgery. RESULTS: Before surgery, the prevalence of objective bulimic episodes was 29 % in the RYGB group and 32 % in the DS group. The prevalence improved during the first 12 months after surgery in both groups. After 5 years, the prevalence of objective bulimic episodes was 22 % in the RYGB group and 7 % in the DS group. The difference between groups throughout follow-up was non-significant (logistic regression model). A linear mixed model showed that global EDE-Q score was not a significant predictor for weight loss after surgery, but participants reporting objective bulimic episodes before surgery had significantly lower BMI than those with no episodes after 2 years (p = 0.042) and 5 years (p = 0.013). Global EDE-Q score was significantly lower in the DS group after 5 years (p = 0.009) (linear mixed model). CONCLUSIONS: Objective bulimic episodes but not global EDE-Q score before surgery predicted greater weight loss after RYGB and DS. The DS group had a significantly lower global EDE-Q score than the RYGB group 5 years after surgery.

OBJECTIVE(S): Sexual function is negatively influenced by endometriosis and women with endometriosis show less sexual and partnership satisfaction compared to patients with other gynaecological disorders. This study aims to compare sexual function between patients with deep infiltrating endometriosis (DIE) and healthy women using Sexual Health Outcomes in Women Questionnaire (SHOW-Q). STUDY DESIGN: Case-control study including 182 patients with histological diagnosis of DIE and 182 healthy women, who referred to our tertiary care university hospital from 2010 to 2012. SHOW-Q was used to collect data concerning satisfaction, orgasm, desire and pelvic problem interference with sex. The un-paired t-test was performed to compare the means of a continuous variable between groups when the data were normally distributed; otherwise the Mann-Whitney test was used to check t-test results. Pearson's χ(2) test and Z-test for proportions - independent groups were performed to investigate the difference among grouping variables. RESULTS: As described in a previous study, the prevalence of sexual dysfunction in women with endometriosis is around 61% and in women with other gynaecological disorders is 35%. Assuming 5% significance and 95% power, 106 women would be required for the study. Every area of sexual function investigated through the SHOW-Q questionnaire (satisfaction, desire, orgasm and pelvic problem interference) was significantly impaired compared to healthy women. Among patients with DIE, 58% (105/182) reported that pelvic pain severely affected sexual function, while only 1% (2/182) of healthy women (p<0.0001). Moreover, sexual desire was absent or less than one or two times per month in 45% (82/182) of women with DIE compared to 14% (26/182) of healthy women (p<0.0001). CONCLUSION(S): DIE severely affects sexual function. Endometriosis is a global disease, which affects patients physically, psychologically and sexually. The potential sexual consequences of this disease need to be considered.
