RESUMO
OBJECTIVE: Plasma D-dimer levels >0.5 mg/L are encountered in various conditions besides venous thromboembolism (VTE). Recent studies use them as a prognostic indicator for systemic and inflammatory diseases. The clinical significance of abnormal levels is unclear in osteomyelitis patients with baseline elevation. Our study reviews the occurrence and significance of >0.5 mg/L D-dimer levels in different types of osteomyelitis. PATIENTS AND METHODS: This study involved 125 individuals, out of which 94 were male and 31 were female. The patients were divided into two groups based on the results of bacterial culture testing. Group A comprised those who tested positive for bacterial culture, while group B included those who tested negative. Out of 68 samples tested, 56% were found to have Staphylococcus aureus. All 125 patients underwent blood testing, which included measuring the D-dimer levels, neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), lymphocyte to monocyte ratio (LMR), and MHR monocyte to high-density lipoprotein cholesterol (HDL-C) ratio in different types of osteomyelitis. The statistical analysis of these tests was carried out. RESULTS: Although there were no significant differences in white blood cell (WBC) count, Neutrophil count, Lymphocyte count, or erythrocyte sedimentation rate (ESR) as well as the NLR, PLR, LMR, MHR, HDL-C ratio. The C-reactive protein (CRP) levels were significantly higher in group A (26.13±50.30) than in group B (10.76±18.70) (p<0.05). D-dimer levels were elevated in 40.8% of patients with bacterial culture-positive osteomyelitis, negative culture osteomyelitis, implants with fractures, and no trauma osteomyelitis. No correlation was found between the increase in D-dimer levels and the presence of bacterial culture or implant-related osteomyelitis in patients. CONCLUSIONS: No significant correlation was found between D-dimers and osteomyelitis, including positive bacterial cultures, implant-related osteomyelitis, or osteomyelitis without trauma. However, 40% of the patients had higher D-dimer levels.

OBJECTIVE: Evaluate days alive and out of the hospital (DAOH) as an outcome measure after orthotopic heart transplantation in patients with mechanical circulatory support (MCS) as a bridge to transplant compared to those patients without prior MCS. DESIGN: A retrospective observational study of adult patients who underwent cardiac transplantation between January 1, 2015, and January 1, 2020. The primary outcome was DAOH at 365 days (DAOH365) after an orthotopic heart transplant. A Poisson regression model was fitted to detect the association between independent variables and DAOH365. SETTING: An academic tertiary referral center. PARTICIPANTS: A total of 235 heart transplant patients were included-103 MCS as a bridge to transplant patients, and 132 direct orthotopic heart transplants without prior MCS. MEASUREMENTS AND MAIN RESULTS: The median DAOH365 for the entire cohort was 348 days (IQR 335.0-354.0). There was no difference in DAOH365 between the MCS patients and patients without MCS (347.0 days [IQR 336.0-353.0] v 348.0 days [IQR 334.0-354.0], p = 0.43). Multivariate analysis identified patients who underwent a transplant after the 2018 heart transplant allocation change, pretransplant pulmonary hypertension, and increased total ischemic time as predictors of reduced DAOH365. CONCLUSIONS: In this analysis of patients undergoing orthotopic heart transplantation, there was no significant difference in DAOH365 in patients with prior MCS as a bridge to transplant compared to those without MCS. Incorporating days alive and out of the hospital into the pre-transplant evaluation may improve understanding and conceptualization of the post-transplantation patient experience and aid in shared decision-making with clinicians.

OBJECTIVE: Non-steroidal anti-inflammatory drugs (NSAIDs) are the most studied chemoprophylaxis for post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP). While previous systematic reviews have shown NSAIDs reduce PEP, their impact on moderate to severe PEP (MSPEP) is unclear. We conducted a systematic review and meta-analysis to understand the impact of NSAIDs on MSPEP among patients who developed PEP. We later surveyed physicians' understanding of that impact. DESIGN: A systematic search for randomized trials using NSAIDs for PEP prevention was conducted. Pooled-prevalence and Odds-ratio of PEP, MSPEP were compared between treated vs. control groups. Analysis was performed using R software. Random-effects model was used for all variables. Physicians were surveyed via email before and after reviewing our results. RESULTS: 7688 patients in 25 trials were included. PEP was significantly reduced to 0.598 (95%CI, 0.47-0.76) in the NSAIDs group. Overall burden of MSPEP was reduced among all patients undergoing ERCP: OR 0.59 (95%CI, 0.42-0.83). However, NSAIDs didn't affect the proportion of MSPEP among those who developed PEP (p = 0.658). Rectal Indomethacin and diclofenac reduced PEP but not MSPEP. Efficacy didn't vary by risk, timing of administration, or bias-risk. Survey revealed a change in the impression of the effect of NSAIDs on MSPEP after reviewing our results. CONCLUSIONS: Rectal diclofenac or indomethacin before or after ERCP reduce the overall burden of MSPEP by reducing the pool of PEP from which it can arise. However, the proportion of MSPEP among patients who developed PEP is unaffected. Therefore, NSAIDs prevent initiation of PEP, but do not affect severity among those that develop PEP. Alternative modalities are needed to reduce MSPEP among patients who develop PEP.

OBJECTIVE: To study the anti-inflammatory and anti-tussive effects of Qingfei Dayuan granules (, QFDY), and to evaluate the acute and sub-chronic toxicity of QFDY. METHODS: Anti-inflammatory effects were evaluated by murine model of xylene induced ear edema in mice. Ear swelling degree was calculated and tumor necrosis factor-α, interleukin-1ß and interleukin-6 were determined. Anti-tussive evaluations were carried out in the mouse cough model induced by ammonia liquor. Latent period cough and number of cough within 3 min were counted. In acute toxicity study, the rats were randomly divided into test group and solvent control group. Body weighs, food intakes and general clinical signs were monitored. In the sub-chronic toxicity study, QFDY was administered to rats at 0, 4, 8 and 16 g/kg per day for 28 and 30 d of post treatment was conducted. Mortalities, clinical signs, body weight changes, food intakes, ophthalmological examinations, hematological parameters, biochemical indicators, electrolyte indicators, urinalyses and histopathological examinations were monitored. RESULTS: QFDY significantly inhibited the development of ear edema in anti-inflammatory assay and decreased cough frequency caused by ammonia liquor. The results presented a dose-effect relationship. In acute toxicity study, no abnormality exhibited at dose of 24.0 g/kg per day during the 14-d observation period. In the sub-chronic toxicity study, higher reticulocyte count, lymphocyte and lower Cl-, blood urea nitrogen were analyzed compared with the solvent control group. But the differences were considered to be incidental and not clinically toxic. Obvious dose-effect relationship of urine color was observed, and the three test groups at the end of the experiments resulted in significant increase in urobilinogen, bilirubin, ketone body and urine leukocyte. However, all the positive indicators returned to normal in the recovery period. Therefore, no toxicological changes were found during the study period. CONCLUSION: QFDY showed significant anti-inflammatory and anti-tussive effects in mice. The lethal dose (LD50) of per oral QFDY in rats was estimated to be more than 24.0 g/kg per day and the no observed adverse effect level was over 16 g/kg per day, which suggested that QFDY is relatively safe for oral medication at the present dose on rats. Our experimental results provide a reference for the further development and research of QFDY.

AbstractPurpose: to characterize ethics course content, structure, resources, pedagogic methods, and opinions among academic administrators and course directors at U.S. medical schools. METHOD: An online questionnaire addressed to academic deans and ethics course directors identified by medical school websites was emailed to 157 Association of American Medical Colleges member medical schools in two successive waves in early 2022. Descriptive statistics were utilized to summarize responses. RESULTS: Representatives from 61 (39%) schools responded. Thirty-two (52%) respondents were course directors; 26 (43%) were deans of academic affairs, medical education, or curriculum; and 3 with other roles also completed the survey (5%). All 61 schools reported some form of formal ethics education during the first year of medical school, with most (n = 54, 89%) reporting a formal mandatory introductory course during preclinical education. Schools primarily utilized lecture and small-group teaching methods. Knowledge-based examinations, attendance, and participation were most commonly used for assessment. A large majority regarded ethics as equally or more important than other foundational courses, but fewer (n = 37, 60%) provided faculty training for teaching ethics. CONCLUSIONS: Despite a response rate of 39 percent, the authors conclude that medical schools include ethics in their curricula in small-group and lecture formats with heterogeneity regarding content taught. Preclinical curricular redesigns must innovate and implement best practices for ensuring sound delivery of ethics content in future curricula. Additional large-scale research is necessary to determine said best practices.

Objective: To investigate the risk factors associated with the development of proximal junctional kyphosis (PJK) after posterior spinal fusion for in children with Lenke type 5 adolescent idiopathic scoliosis (AIS). Methods: It was a retrospective case-control study that included medical records of 98 children with Lenke type 5 AIS who underwent posterior orthopedic surgery under general anesthesia at the Honghui Hospital Affiliated to Xi'an Jiaotong University from January 2013 to December 2018. There were 23 males and 75 females with a mean age of (14.5±2.2) years (10-18 years). Patients were divided into PJK and non-PJK groups according to whether the posterior junctional angle (PJA) was greater than 10° and increased for more than 10° from the preoperative period at the the last follow-up. Univariate analysis was used to analyze the correlation of general data of the children with occurrence of PJK after the operation. Multivariate logistic regression analysis was used to analyze the risk factors of postoperative PJK. Results: There were 35 cases in the PJK group and 63 cases in the non-PJK group. The PJK and non-PJK groups were followed up for (35.6±7.3) months and (36.4±7.5) months, respectively, and the difference was not statistically significant (P=0.637). There was no statistically significant difference between the two groups in general data such as gender, age, and body mass index (all P>0.05), while there were statistically significant differences between the two groups in upper instrumented vertebrea (UIV) location and junctional area posterior ligamentous complex (PLC) injury (all P<0.05). The results of univariate analysis showed that UIV location at T10-T12, junctional area PLC injury, preoperative coronal thoracic curve (TC), preoperative and final follow-up PJA, and preoperative and final follow-up pelvic incidence-lumbarlordosis (PI-LL) were correlated with postoperative PJK (OR=2.50, 5.37, 0.92, 1.12, 1.32, 1.06, 3.35, all P<0.05). Multifactorial logistic regression analysis showed that UIV located at T10-T12 (OR=2.346, 95%CI: 1.582-3.481, P=0.001), junctional area PLC injury (OR=5.112, 95%CI: 1.283-20.418, P=0.023) and last follow-up PI-LL (OR=1.826, 95%CI: 1.558-24.745, P=0.012) were risk factors for the occurrence of postoperative PJK in children with Lenke type 5 AIS. Conclusions: Postoperative UIV fixation to the thoracolumbar segment, PLC injury in the junctional area and excessive postoperative PI-LL in children with Lenke type 5 AIS may be the risk factors for the occurrence of PJK after the operation. It is suggested that avoidance of UIV selection to the thoracolumbar segment, intraoperative protection of the PLC located near the UIV and restoration of a good PI-LL relationship may reduce the incidence of PJK.

BACKGROUND: Literature evaluating intraoperative temperature/humidity and risk of surgical site infection (SSI) is lacking. METHODS: All operations at three centers reported to the ACS-NSQIP were reviewed (2016-2020); ambient intraoperative temperature (°F) and relative humidity (RH) were recorded in 15-min intervals. The primary endpoint was superficial SSI, which was evaluated with multi-level logistic regression. RESULTS: 14,519 operations were analyzed with 179 SSIs (1.2%). The lower/upper 10th percentiles for temperature and RH were 64.4/71.4 °F and 33.5/55.5% respectively. Low or high temperature carried no significant increased risk for SSI (Low °F OR = 0.95, 95% CI 0.51-1.77, P = 0.86; High °F OR = 1.13, 95% CI = 0.69-1.86, P = 0.63). This was also true for low and high RH (Low RH OR = 0.96, 95% CI 0.58-1.61, p = 0.88; High RH OR = 0.61, 95% CI = 0.33-1.14, P = 0.12). Analysis of combined temperature/humidity showed no increased risk for SSI. CONCLUSION: Significant deviations in intraoperative temperature/humidity are not associated with increased risk of SSI.

OBJECTIVE: To investigate the effect of Tuina on the plasma metabolites of lipopolysaccharide-induced febrile in infant rabbits. METHODS: Twenty-four infant New Zealand rabbits were selected and randomly divided into three groups: saline, model, and Tuina. The fever model was established by injecting LPS intravenously through the ear margin vein in the model group and Tuina group, respectively. The modeling was considered successful when the anal temperature increased by 0.5â or above within 1 h. In the Tuina group, six Tuina techniques (i.e., opening Tianmen / the heaven gate, pushing Kangong / the superciliary arch, kneading Taiyang and the prominent bone behind the ears, clearing Tianheshui, spine pinching) that alleviate fever were performed on the young rabbits 1 h after the modeling, whereas the model and saline groups were not given Tuina treatment, with the real-time anal temperature monitored during the experiment. The plasma was taken 3 h after the modeling for liquid chromatography-mass spectrometry (LC-MS) untargeted metabolomics study. RESULTS: Our results showed a fever-reducing effects of Tuina therapy on lipopolysaccharide-induced fever in young rabbits, as indicated by a significantly lower anal temperature, maximum rise in body temperature, and body response index at 2 and 3 h after modeling in the Tuina group compared to the model group, with reductions in the PGE2 expression observed in the blood and hypothalamus. The differential metabolites including riboflavin, nicotinamide N-oxide, porphobilinogen, 5-hydroxyindoleacetic acid, gamma-aminobutyric acid, and lysoPC (16:1 (9Z)/0:0) were found following the Tuina intervention. Tuina primarily involves glycine-serine-threonine, arginine-proline, porphyrin-chlorophyll, pyrimidine, primary bile acid biosynthesis, and cyanoamino acid metabolic pathways. CONCLUSION: Tuina therapy has proven to be effective in reducing body temperature and down-regulating PGE2 expression in LPS-induced febrile young rabbits, with its mechanism of fever-reducing action possibly associated with the changes in plasma metabolites and metabolic pathways.

INTRODUCTION: Surgical site infections are common postoperative complications. Some operating rooms have open-floor drainage systems for fluid disposal during endourologic cases, although nonendoscopy cases are not always allowed in these rooms. We hypothesized that operating rooms with open-floor drainage systems would not materially affect risk of surgical site infections for patients undergoing open and laparoscopic procedures. METHODS: Patients who had surgical site infections from 2016 through 2020 were identified from data of the National Surgical Quality Improvement Program. Patients without surgical incisions, with open wounds, and with surgical site infections at surgery were excluded. The primary outcome was surgical site infection occurrence within 30 days of surgery. Multilevel multivariable logistic regression was used to estimate the observed-to-expected surgical site infection ratio for each operating room (2 with and 23 without open-floor drainage systems). RESULTS: We identified 8,419 surgical cases, of which 802 (9.5%) were performed in operating rooms with open-floor drainage systems; 166 patients (2.0%) had surgical site infections. Of the surgical site infections, 7 (4.2%) occurred in operating rooms with open-floor drainage systems. Surgical specialty, American Society of Anesthesiologists physical status, higher case acuity, dyspnea, immunosuppression, longer surgical duration, and wound classification were associated with surgical site infections (P < .05 for all). The observed-to-expected ratios of surgical site infections occurring in the 2 operating rooms with open-floor drainage systems were 0.85 and 1.15. The odds ratio of surgical site infections for urologic cases performed in room with vs without open-floor drainage systems was 1.30 (P = .65). CONCLUSIONS: Urology operating room designs often include open-floor drainage systems for water-based cases. These drainage systems were not associated with an increased risk of surgical site infections.
RESUMO
Rheumatology research often involves correlated and clustered data. A common error when analyzing these data occurs when instead we treat these data as independent observations. This can lead to incorrect statistical inference. The data used are a subset of the 2017 study from Raheel et al consisting of 633 patients with rheumatoid arthritis (RA) between 1988 and 2007. RA flare and the number of swollen joints served as our binary and continuous outcomes, respectively. Generalized linear models (GLM) were fitted for each, while adjusting for rheumatoid factor (RF) positivity and sex. Additionally, a generalized linear mixed model with a random intercept and a generalized estimating equation were used to model RA flare and the number of swollen joints, respectively, to take additional correlation into account. The GLM's ß coefficients and their 95% confidence intervals (CIs) are then compared to their mixed-effects equivalents. The ß coefficients compared between methodologies are very similar. However, their standard errors increase when correlation is accounted for. As a result, if the additional correlations are not considered, the standard error can be underestimated. This results in an overestimated effect size, narrower CIs, increased type I error, and a smaller P value, thus potentially producing misleading results. It is important to model the additional correlation that occurs in correlated data.

In 2018, periprosthetic joint infection (PJI) criteria were revised to include a new category labeled "inconclusive." The purpose of this study was to characterize and describe the fate of the inconclusive PJI workup and to analyze preoperative factors associated with outcomes. We reviewed all PJI workups at our institution during a 3-year period (426 patients). Patients were labeled "infected," "not infected," or "inconclusive" according to 2018 PJI preoperative criteria. In addition to standard diagnostic variables, the presence or absence of clinical elements that increase the pretest probability of infection were collected. Patients with any missing preoperative diagnostic test results and those with clinical follow-up less than 30 days were excluded. Logistic regression was used to identify the factors associated with infection. Two hundred ninety-six workups remained after exclusion criteria were applied, consisting of 66 (22.2%) with a preoperative score of 6 or greater defined as infected, 52 (17.6%) inconclusive (score 2-5), and 178 (60.1%) not infected (score 0-1). Postoperative re-scoring of the inconclusive group based on intraoperative findings as per the 2018 criteria identified 6 of 52 (11.5%) as infected, 12 (23.1%) inconclusive, and 34 (65.4%) not infected. Among those preoperatively scored as inconclusive, variables statistically correlated with the presence of infection included history of PJI, factors that increase skin barrier penetration (eg, psoriasis and venous stasis), and presence of comorbidities predisposing to infection. For patients labeled inconclusive, clinical elements of the pretest probability for infection (eg, history of prior PJI) were as reliable as any diagnostic test, including alpha-defensin, in the diagnosis of PJI.

BACKGROUND: In response to the opioid epidemic, the United States declared a public health emergency in 2017. We evaluated pain medication prescribing practices among plastic and reconstructive surgeons, assessing pain medication prescription rates and opioid-related mortality both nationally and regionally within the United States. METHODS: A retrospective analysis of Medicare Part D prescriber data among plastic surgeons from 2013 through 2017 was conducted. Pain medications were categorized as opioid and nonopioid medications. Trends in surgeon prescribing habits were evaluated using the Cochrane-Armitage trend test. RESULTS: A total of 708,817 pain medication claims were identified: 612,123 claims (86%) were for opioid pain medications and 96,694 claims (14%) were for nonopioid pain medications. Total pain medication claims decreased from 44% of all medications in 2013 to 37% in 2017 (P < 0.001). Opioid medications decreased from 37% of total medication claims to 32% (P < 0.001). The overall opioid prescription rate fell from 1.53 claims per beneficiary in 2013 to 1.32 in 2017 (P < 0.001). Nonopioid pain medications decreased from 7% in 2013 to 6% in 2017 (P < 0.001); nonsteroidal anti-inflammatory drug claims increased by 44%. The prescription rate of nonopioid medications decreased from 2.40 claims per beneficiary in 2013 to 2.32 in 2017 (P < 0.001). An overall increase in opioid-related mortality was observed. Trends in pain medication prescriptions varied significantly among US regions and divisions. CONCLUSIONS: Plastic surgeons are prescribing less opioids and relying more on nonopioid pain medications. Increased adoption of multimodal pain treatment approaches among surgeons is a likely explanation for this trend in face of the current opioid crisis.

Cost-effective and safe air disinfection methods are urgently needed in various environmental public settings. A novel UVC-based disinfection system was designed and tested to provide a promising solution because of its effective inactivation of indoor bioaerosols at a low cost. UVC light-emitting diodes (UVC-LEDs) were utilized as the irradiation source. This system has the unique feature of rotating the UVC-LEDs to generate a "scanning irradiation" zone. Escherichia coli was aerosolized into an experimental chamber, exposed to UVC-LEDs, and sampled using an impactor. Effects of air mixing (well-mixed vs. poorly-mixed), transmission range (short vs. long), and irradiation mode (stationary vs. rotating) were evaluated. The system performs significantly well under the poorly-mixed condition. The results obtained from the short disinfection range indicate that the rotating UVC was approximately 70.5 % more effective than the stationary UVC for the poorly-mixed case. Further, we evaluated the performance of the long disinfection range under a poorly-mixed situation, and the disinfection efficacy was 84.6 % higher for the rotating irradiation than that of the stationary. About 0.59-1.34 J/m2 UV dose can be used to obtain one-log inactivation of E. coli. In conclusion, the novel rotating upper-room UVC-LED system is effective in reducing indoor pathogen transmission, and our findings are highly significant to a growing field where LEDs are applied for disinfection.

INTRODUCTION: The use of alvimopan at the time of cystectomy has been associated with improved perioperative outcomes. Naloxegol is a less costly alternative that has been used in some centers. This study aims to compare the perioperative outcomes of patients undergoing cystectomy with urinary diversion who receive the mu-opioid antagonist alvimopan versus naloxegol. MATERIALS AND METHODS: This was a retrospective review that included all patients who underwent cystectomy with urinary diversion at our institution between 2007-2020. Comparisons were made between patients who received perioperative alvimopan, naloxegol and no mu-opioid antagonist (controls). RESULTS: In 715 patients who underwent cystectomy, 335 received a perioperative mu-opioid antagonist, of whom 57 received naloxegol. Control patients, compared to naloxegol and alvimopan patients, experienced a significantly (p < 0.05) delayed return of bowel function (4.3 vs. 2.5 vs. 3.0 days) and longer hospital length of stay (7.9 vs. 7.5 vs. 6.5 days), respectively. The incidence of nasogastric tube use (14.2% vs. 12.5% vs. 6.5%) and postoperative ileus (21.6% vs. 21.1% vs. 13.3%) was also most common in the control group compared to the naloxegol and alvimopan cohorts, respectively. A multivariable analysis revealed that when comparing naloxegol and alvimopan, there was no difference in return of bowel function (OR 0.88, p = 0.17), incidence of postoperative ileus (OR 1.60, p = 0.44), or hospital readmission (OR 1.22, p = 0.63). CONCLUSIONS: Naloxegol expedites the return of bowel function to the same degree as alvimopan in cystectomy patients. Given the lower cost of naloxegol, this agent may be a preferable alternative to alvimopan.

PURPOSE: The tumor immune microenvironment impacts the biological behavior of the tumor, but its effect on clinical outcomes in head and neck cutaneous squamous cell carcinomas (HNcSCC) is largely unknown. EXPERIMENTAL DESIGN: We compared the immune milieu of high-risk HNcSCC that never progressed to metastasis with those that metastasized using multiparameter imaging mass cytometry. The cohort included both immunosuppressed patients (IS) and patients with an absence of clinical immune-suppression (ACIS). Spatial analyses were used to identify cellular interactions that were associated with tumor behavior. RESULTS: Nonprogressing primary HNcSCC were characterized by higher CD8+ and CD4+ T-cell responses, including numerically increased regulatory T cells. In contrast, primary lesions from HNcSCC patients who progressed were largely devoid of T cells with lower numbers of innate immune cells and increased expression of checkpoint receptors and in the metastatic lesions were characterized by an accumulation of B cells. Spatial analysis reveals multiple cellular interactions associated with nonprogressing primary tumors that were distinct in primary tumors of disease-progressing patients. Cellular regional analysis of the tumor microenvironment also shows squamous cell-enriched tumor regions associated with primary nonprogressing tumors. CONCLUSIONS: Effective responses from both CD8+ and CD4+ T cells in the tumor microenvironment are essential for immune control of primary HNcSCC. Our findings indicate that the early events that shape the immune responses in primary tumors dictate progression and disease outcomes in HNcSCC.

Neoadjuvant chemotherapy allows a minimally invasive approach for interval debulking in patients with ovarian cancer considered unresectable to no residual disease by laparotomy at diagnosis. The aim of the study was to evaluate the type of surgical approach at interval debulking (ID) after three courses of carboplatin and taxol in patients with unresectable ovarian cancer at diagnosis compared with the type of surgical approach at primary debulking (PD). A secondary objective was to compare the perioperative outcomes of MIS vs. laparotomy at ID. A retrospective review of the type of surgical approach at ID following three courses of carboplatin and taxol was compared with the surgical approach at PD, and a review of the perioperative outcomes of MIS vs. open at ID was performed during the period from 21 January 2012, through 21 February 2013, for stage IIIC > 2 cm or IV epithelial ovarian cancer (EOC) unresectable at diagnosis and the surgical approach at PD. During the study period, 127 patients with stage IIIC or IV EOC met the inclusion criteria. Minimally invasive surgery (MIS), laparoscopic or robotic, was used in 21.6% of patients at ID and in 23.3% of patients at PD. At ID, MIS patients had a shorter hospital stay as compared to laparotomy (2 vs. 8 days; p < 0.001). At 5 year follow-up, 31.5% of EOC patients were alive (ID MIS: 47.5% vs. ID open: 30%; PD MIS: 41% vs. PD open: 28%), while 24.4% had no evidence of disease (ID MIS: 39% vs. ID open: 19.5%; PD MIS: 32% vs. PD open: 22%). Among living patients, 22% had evidence of disease. Neoadjuvant chemotherapy is a form of chemo-debulking and allows a minimally invasive approach at interval debulking in about one-fifth of the patients, with initial disease deemed unresectable to no residual tumor at initial diagnosis.
RESUMO
PURPOSE: Use of the electronic health record (EHR) during face-to-face clinical encounters affects communication, and prior research has been inconclusive regarding its effect. This survey study assessed health care practitioner use of EHR-specific communication skills and patient and practitioner experiences and attitudes regarding EHR use during clinical encounters. METHODS: For this US-based study, we distributed previously validated surveys to practitioners and adult patients (aged >18 years) at academic primary care practices from July 1, 2018 through August 31, 2018. The electronic practitioner survey was completed first; a paper survey was administered to patients after appointments. Descriptive statistics were calculated, and the Cochran-Armitage test was used to assess for associations between key variables. RESULTS: The practitioner response was 72.9% (43/59); patient response, 45.2% (452/1,000). Practitioners reported maintaining less eye contact (79.1%), listening less carefully (53.5%), focusing less on patients (65.1%), and visits feeling less personal (62.8%). However, patients reported that practitioners provided sufficient eye contact (96.8%) and listened carefully (97.0%); they disagreed that practitioners focused less on them (86.7%) or that visits felt less personal (87.2%). Patients thought EHR use was positive (91.7%); only one-third of practitioners (37.2%) thought that patients would agree with that statement. Practitioners reported stress, burnout, and a lack of sufficient time for EHR documentation. CONCLUSIONS: A discrepancy existed in this study between patient and practitioner experiences and attitudes about EHR use, which appeared to negatively affect the experience of health care practitioners but not patients. Organizations should adopt formal strategies to improve practitioner experiences with EHR use.

The efficacy of the in-duct application of ultraviolet waveband C (UVC) emitting at 254 nm wavelength and air ions against aerosolized bacteria was studied in a full-scale 9-m long ventilation duct. Combined positive and negative ion polarities (bipolar ions) and combined UVC and ions were tested. The UVC was generated by a mercury-type UVC lamp and air ions were generated by positive and negative polarity ionizers. Escherichia coli (E. coli), Salmonella typhimurium (S. typhimurium), and Staphylococcus epidermidis (S. epidermidis)were tested at a concentration of 108 to 109 cells in 50 ml of sterilized distilled water. The case in which the positive ionizer was placed first, followed by the negative ionizer, demonstrated significantly higher disinfection efficiencies for E. coli (p = 0.007) and S. typhimurium (p < 0.001), but lower efficiency for S. epidermidis (p = 0.01) than the reversed sequence. The combination of UVC (3.71 J/m2 ) and air ions (1.13 × 1012 ions/m3 for positive ions and 8.00 × 1011 ions/m3 for negative ions) led to higher inactivation than individual disinfection agents operating under the same dose. A synergetic inactivation effect was observed for S. epidermidis under the combined UVC and positive ion case, while the combined UVC and negative ion case showed significant synergy effects for E. coli and S. typhimurium.
