Effect of extra virgin olive oil consumption on glycemic control: A systematic review and meta-analysis

Nutr Metab Cardiovasc Dis. 2021 Feb 24:S0939-4753(21)00086-7. doi: 10.1016/j.numecd.2021.02.017. Online ahead of print.

ABSTRACT

AIMS: Several health benefits are contributed to extra virgin olive oil (EVOO). The polyphenol fraction of EVOO may be responsible for its cardioprotective impacts. This systematic review and meta-analysis aimed to investigate the effect of EVOO intake on glycemic parameters. Electronic literature searched through 1 September 2020 across MEDLINE/PubMed, Web of Science, and SCOPUS databases to find all clinical trials that reported the effect of EVOO intake on glycemic parameters [FBS(fasting blood glucose), insulin, HOMA-IR (Homeostatic Model Assessment for Insulin Resistance) and HbA1c (glycated hemoglobin A1c)] vs. control.

DATA SYNTHESIS: We pooled standardized mean differences (SMD) and 95% confidence intervals (CIs) from randomized clinical trials (RCTs) using random-effects models. Heterogeneity was assessed by Cochran Q-statistic and quantified (I2). We found 13 related trials comprising a total of 633 subjects. In pooled analysis, EVOO intake had no effect on FBS (SMD: -0.07; 95% CI: -0.20, 0.07; I2 = 0.0%), insulin (SMD: -0.32; 95% CI: -0.70, 0.06; I2 = 38.0%), and HOMA-IR (SMD: -0.32; 95% CI: -0.75, 0.10; I2 = 51.0%). However, a decreasing trend was observed in these effects. Subgroup analysis based on age, health status, dose, and EVOO intake duration also did not significantly change results.

CONCLUSION: Although EVOO seems a promising hypoglycemic effects, we did not find any significant evidence that EVOO consumption impacts glucose homeostasis. Furthermore, well-designed RCTs with longer durations are still needed to evaluate the EVOO’s efficacy on glycemic parameters.

A clinicoradiological classification and a treatment algorithm for traumatic triceps tendon avulsion in adults

Chin J Traumatol. 2021 Feb 27:S1008-1275(21)00031-6. doi: 10.1016/j.cjtee.2021.02.008. Online ahead of print.

ABSTRACT

PURPOSE: Triceps tendon avulsion (TTA) is an uncommon injury, and there are no classifications or treatment guidelines available. This study aims to describe a clinicoradiological classification and treatment algorithm for traumatic TTA in adults. The functional outcome of surgical repair has been evaluated too.

METHODS: A retrospective analysis of adult patients with traumatic TTA treated in our institution between 2012 and 2017 was done. We only included complete TTA injuries. Children below 15 years, open injuries, associated fractures, and partial TTA were excluded. The data were obtained from hospital records. The intraoperative findings were correlated with the clinicoradiological presentation for classifying TTA. The functional outcome was analyzed using the Mayo Elbow Performance index and Hospital for Special Surgery elbow score. ANOVA test was used to assess the statistical significance.

RESULTS: There were 15 patients included, including 11 males and 4 females. The mean age was (31.5 ± 9.15) years, and the mean follow-up was (22.4 ± 8.4) months. Fall on outstretched hand was the mode of injury. In 6 patients, diagnosis was missed on the initial visit. TTA were classified as Type 1: palpable soft-tissue defect without bony mass; Type 2: palpable soft-tissue defect with a wafer-thin/comminuted bony fragment on X-ray; Type 3: palpable soft-tissue defect with a bony mass and a large bony fragment on X-ray without extension to the articular surface; and Type 4: an olecranon fracture with less than 25% of the articular surface. An algorithm for treatment was recommended, i.e. transosseous suture repair/suture anchor for Type 1, transosseous suture repair for Type 2, and tension band wiring or steel wire sutures for Types 3 and 4. All the patients achieved good to excellent outcome: the mean Mayo Elbow Performance index was 100 and Hospital for Special Surgery score was 98.26 ± 2.60 on final follow-up.

CONCLUSION: Our clinicoradiological classification and treatment algorithm for TTAs is simple. Surgical treatment results in excellent functions of the elbow. Since it is a single-center study involving a very small number of cases, a multicenter study with a larger number of patients is required for external validation of our classification and treatment recommendations.

Missed childhood immunizations during the COVID-19 pandemic in Brazil: Analyses of routine statistics and of a national household survey

Vaccine. 2021 Apr 27:S0264-410X(21)00505-3. doi: 10.1016/j.vaccine.2021.04.046. Online ahead of print.

ABSTRACT

INTRODUCTION: There is widespread concern that disruption to health services during the COVID-19 pandemic has led to declines in immunization coverage among young children, but there is limited information on the magnitude of such impact. High immunization coverage is essential for reducing the risk of vaccine preventable diseases.

METHODS: We used data from two nationwide sources covering the whole of Brazil. Data from the Information System of the National Immunization Program (SIPNI) on the monthly number of vaccine doses administered to young children were analyzed. The second source was a survey in 133 large cities in the 27 states in the country, carried out from August 24-27. Respondents answered a question on whether children under the age of three years had missed any scheduled vaccinations during the pandemic, and available vaccination cards were photographed for later examination.

RESULTS: SIPNI data showed that, relative to January and February 2020, there was a decline of about 20% in vaccines administered to children aged two months or older during March and April, when social distancing was at the highest level in the country. After May, vaccination levels returned to pre-pandemic values. Survey data, based on the interviews and on examination of the vaccine cards, showed that 19.0% (95% CI 17.0;21.1%) and 20.6% (95% CI 19.0;23.1%) of children, respectively, had missed immunizations. Missed doses were most common in the North (Amazon) region and least common in the South and Southeast, and also more common among children from poor than from wealthy families.

INTERPRETATION: Our results show that the pandemic was associated with a reduction of about 20% in child vaccinations, but this was reverted in recent months. Children from poor families and from the least developed regions of the country were most affected. There is an urgent need to booster immunization activities in the country to compensate for missed doses, and to reduce geographic and socioeconomic inequalities.

Carotid Ultrasound Boundary Study (CUBS): An Open Multicenter Analysis of Computerized Intima-Media Thickness Measurement Systems and Their Clinical Impact

Ultrasound Med Biol. 2021 Apr 30:S0301-5629(21)00141-1. doi: 10.1016/j.ultrasmedbio.2021.03.022. Online ahead of print.

ABSTRACT

Common carotid intima-media thickness (CIMT) is a commonly used marker for atherosclerosis and is often computed in carotid ultrasound images. An analysis of different computerized techniques for CIMT measurement and their clinical impacts on the same patient data set is lacking. Here we compared and assessed five computerized CIMT algorithms against three expert analysts’ manual measurements on a data set of 1088 patients from two centers. Inter- and intra-observer variability was assessed, and the computerized CIMT values were compared with those manually obtained. The CIMT measurements were used to assess the correlation with clinical parameters, cardiovascular event prediction through a generalized linear model and the Kaplan-Meier hazard ratio. CIMT measurements obtained with a skilled analyst’s segmentation and the computerized segmentation were comparable in statistical analyses, suggesting they can be used interchangeably for CIMT quantification and clinical outcome investigation. To facilitate future studies, the entire data set used is made publicly available for the community at http://dx.doi.org/10.17632/fpv535fss7.1.

Poor guideline adherence in type 1 diabetes education in real-world clinical practice: Evidence from a multicentre, national survey

Patient Educ Couns. 2021 Apr 17:S0738-3991(21)00248-2. doi: 10.1016/j.pec.2021.04.010. Online ahead of print.

ABSTRACT

OBJECTIVE: To examine how physicians implement guidelines to deliver insulin dosing education for type 1 diabetes patients in real-world settings.

METHODS: A nationally representative sample of endocrinologists from top tertiary hospitals in China was obtained by a multistage random sampling method (n = 385). Knowledge, perceptions and practices of insulin dosing were assessed by validated questionnaires. Multivariable logistic regression was used to identify independent determinants of clinical practice and knowledge.

RESULTS: Only 20.5% of endocrinologists correctly answered> 75% of the items regarding insulin dosing knowledge. Only 37.7% of endocrinologists reported often teaching insulin-to-carbohydrate ratio and insulin sensitivity factor. Practice behaviours were independently associated with guideline familiarity (OR: 5.92, 95% CI: 3.36-10.41), receiving standardized training (OR: 2.00, 95% CI:1.23-3.25), self-reported lack of time (OR: 0.58, 95% CI:0.34-0.99) and insufficient teaching approaches (OR: 0.57, 95% CI:0.33-0.97) CONCLUSIONS: There was a large gap between guidelines and clinical practice in insulin dosing education. Modifiable factors, including self-reported lack of time, unfamiliarity with guidelines, the shortage of medical training and educational tools hinder insulin dosing education.

PRACTICE IMPLICATIONS: Sufficient medical training and educational tools are important to optimize insulin dosing education. The current care paradigm should also be modified to relieve the burden of physicians.

Expanding telehealth options during the COVID pandemic eliminated racial and age disparities in electronic communication by inflammatory bowel disease patients

J Natl Med Assoc. 2021 Apr 30:S0027-9684(21)00052-3. doi: 10.1016/j.jnma.2021.03.005. Online ahead of print.

ABSTRACT

BACKGROUND: Electronic messaging and telemedicine visits increased during the COVID pandemic. African-Americans and older patients have less frequently used electronic messaging with their physicians. This study compares the utilization of virtual health care before and during the COVID pandemic for inflammatory bowel disease (IBD) patients.

METHODS: A chart review of all IBD patients seen at an academic medical center from 2014-2020 was conducted to evaluate the use of telehealth options (e-messaging, e-visits) during a pre-COVID and COVID timeframe. Analysis of telehealth use from March – August 2018 and March – August 2020 was performed. Patient age, gender, race, IBD type, electronic messaging and telehealth visits were obtained. A confidential database was created. Statistical analysis was performed using Fisher Exact test with significance set at p < 0.05. The study was IRB approved.

RESULTS: 392 patients were in the pre-COVID cohort. There were 204 White, 99 African-American, 11 Asian, and 78 racially un-identified patients. 160 (40.8%) initiated E-communication with their physicians. There was a significant difference in the use of e-messaging based upon age (51.1% < 50 vs 39.7% ≥ 50; p = 0.0396) and race (62.3% White vs 28.2% African-American; p < 0.00001).There were no significant differences in the use of e-messaging based upon patient gender (p = 0.6840) or IBD type (p = 0.6374). There were 295 patients in the COVID cohort. There were 155 White, 83 African American patients, 24 Hispanic patients, 10 Asian patients, and 22 racially un-identified patients. 109 (36.9%) utilized a telehealth option (53 via e-messaging; 56 via telemedicine visit). There was no significant difference in the use of a telehealth option based upon age (36.8% < 50 vs 37.25% ≥ 50 years; p = 1.00), race (42.6% White vs 35.9% African-American; p = 0.2693) or IBD type (p = 0.331). Males used telehealth more than females (46.1% vs 29.7%, respectively; p = 0.0051).

DISCUSSION: The COVID pandemic emergency increased e-visits and e-messaging for care delivery. Expanded telemedicine options for IBD patients eliminated previously identified racial and age disparities in virtual medical care. African Americans utilized electronic communication as frequently as Whites during the pandemic. Post-pandemic policy consideration for continued telemedicine options may expand patient-physician engagement and eliminate disparities in health care.

Genetics, not the uterine environment, drive the formation of trophoblast inclusions: Insights from a twin study

Placenta. 2021 Apr 18:S0143-4004(21)00128-4. doi: 10.1016/j.placenta.2021.04.010. Online ahead of print.

ABSTRACT

INTRODUCTION: Trophoblast inclusions (TIs) are associated with aneuploidy and pregnancy loss and have thus been considered to be a marker of genetic abnormality. However, to date, no study has specifically explored whether TIs are a manifestation of fetal genetics or, rather, the result of the intrauterine environment. The goal of this study was to compare the frequency of TIs in the placentas of monozygotic (MZ) and dizygotic (DZ) twin pairs in order to determine whether the formation of TIs is genetically driven or not.

METHODS: We performed a retrospective case series of placentas from 48 twin pairs. The placentas were grouped based on zygosity: MZ, DZ, or unknown (UZ). The average number of total TIs per slide was calculated for each twin individual and the mean absolute difference in the total TIs per slide between the twin pairs was calculated for each zygosity group and compared.

RESULTS: The mean difference in the total TIs per slide for DZ twins was significantly greater than the mean difference in the total TIs per slide for MZ twins (p = 0.003). The mean difference in the total TIs per slide for the UZ group was also significantly greater than the mean difference in total TIs per slide between MZ twin pairs (p = 0.028).

DISCUSSION: Our finding that MZ twins were significantly more concordant than DZ twins for the average number of TIs per slide supports the conclusion that TIs are intrinsic to the genetics of the fetus, not the uterine environment.

Combined Effect of a Polygenic Risk Score and Rare Genetic Variants on Prostate Cancer Risk

Eur Urol. 2021 May 1:S0302-2838(21)00253-0. doi: 10.1016/j.eururo.2021.04.013. Online ahead of print.

ABSTRACT

Although prostate cancer is known to have a strong genetic basis and is influenced by both common and rare variants, the ability to investigate the combined effect of such genetic risk factors has been limited to date. We conducted an investigation of 81 094 men from the UK Biobank, including 3568 prostate cancer cases, to examine the combined effect of rare pathogenic/likely pathogenic/deleterious (P/LP/D) germline variants and common prostate cancer risk variants, measured using a polygenic risk score (PRS), on prostate cancer risk. The absolute risk of prostate cancer for HOXB13, BRCA2, ATM, and CHEK2 P/LP/D carriers ranged from 9% to 56%, and the absolute risk in noncarriers ranged from 2% to 31%, by age 85 yr, for men in the lowest and highest PRS decile, respectively. The high-penetrant HOXB13 G84E prostate cancer risk variant was most common in cases in the lowest PRS quintile (4.4%) and least common in cases in the highest PRS quintile (0.5%; p = 0.005), whereas there was no statistically significant difference in frequencies by PRS in controls. While rare and common variants strongly and distinctly influence prostate cancer onset, consideration of rare and common variants in conjunction will lead to more precise estimates of a man’s lifetime risk of prostate cancer. PATIENT SUMMARY: We found that the risk of prostate cancer conveyed by rare variants could vary depending on an individual’s genetic profile of common risk variants. This implies that in order to comprehensively assess genetic risk of prostate cancer, it is important to consider both rare and common variants.

The regression of the bovine tuberculin reaction: Results from the Reactor Quality Assurance study in Northern Ireland

Vet J. 2021 Jun;272:105664. doi: 10.1016/j.tvjl.2021.105664. Epub 2021 Mar 26.

ABSTRACT

Tuberculin skin tests remain widely used in the control of bovine tuberculosis (bTB) in cattle. Little is known about the rate of regression of tuberculin reactions after the comparative intradermal cervical test (CICT) in cattle. This study aimed to collect data to describe tuberculin regression in reactors following the CICT at 72 ± 4 h post injection. Reactors were also tested using the interferon gamma (IFN-γ) assay to establish if any pattern existed between these results and the CICT reaction regression. The data were derived from 108 herds, 112 herd-level CICTs and 1008 animals. A multivariable linear mixed model was built to explore the regression of the bovine tuberculin reaction over time and the influence of potential predictors. The results confirmed a proportional decline in the bovine tuberculin reaction occurred over time. The predictors in the final model demonstrated that regression of the tuberculin reaction differed between reactors according to their IFN-γ test results and whether visible lesions were present at slaughter. Follow-up measurement of tuberculin reactions and the serial use of the IFN-γ assay in large breakdowns has the potential to provide both a mechanism for quality assurance of the current CICT bTB surveillance and the identification of atypical breakdowns or reactors requiring further investigation.

68Ga-PSMA-11 PET, 18F-PSMA-1007 PET, and MRI for Gross Tumor Volume Delineation in Primary Prostate Cancer: Intermodality and Intertracer Variability

Pract Radiat Oncol. 2021 May-Jun;11(3):202-211. doi: 10.1016/j.prro.2020.11.006.

ABSTRACT

PURPOSE: To assess the intermodality and intertracer variability of gallium-68 (68Ga)- or fluorine-18 (18F)-labeled prostate-specific membrane antigen (PSMA) positron emission tomography (PET) and biparametric magnetic resonance imaging (bpMRI)-based gross tumor volume (GTV) delineation for focal boosting in primary prostate cancer.

METHODS: Nineteen prospectively enrolled patients with prostate cancer underwent a PSMA PET/MRI scan, divided into a 1:1 ratio between 68Ga-PSMA-11 and 18F-PSMA-1007, before radical prostatectomy (IWT140193). Four delineation teams performed manual contouring of the GTV based on bpMRI and PSMA PET imaging, separately. Index lesion coverage (overlap%) and interobserver variability were assessed. Furthermore, the distribution of the voxelwise normalized standardized uptake values (SUV%) was determined for the majority-voted (>50%) GTV (GTVmajority) and whole prostate gland to investigate intertracer variability. The median patientwise SUV% contrast ratio (SUV%-CR, calculated as median GTVmajority SUV% / median prostate gland without GTVmajority SUV%) was calculated according to the tracer used.

RESULTS: A significant difference in overlap% favoring PSMA PET compared with bpMRI was found in the 18F subgroup (median, 63.0% vs 53.1%; P = .004) but was not present in the 68Ga subgroup (32.5% vs 50.6%; P = .100). Regarding interobserver variability, measured Sørensen-Dice coefficients (0.58 vs 0.72) and calculated mean distances to agreement (2.44 mm vs 1.22 mm) were statistically significantly lower and higher, respectively, for the 18F cohort compared with the 68Ga cohort. For the bpMRI-based delineations, the median Sørensen-Dice coefficient and mean distance to agreement were 0.63 and 1.76 mm, respectively. Median patientwise SUV%-CRs of 1.8 (interquartile range [IQR], 1.6-2.7) for 18F-PSMA and 3.3 (IQR, 2.7-5.9) for 68Ga-PSMA PET images were found.

CONCLUSIONS: Both MRI and PSMA PET provided consistent intraprostatic GTV lesion detection. However, the PSMA tracer seems to have a major influence on the contour characteristics, owing to an apparent difference in SUV% distribution in the prostate gland.
