ABSTRACT

IMPORTANCE: New and expectant parents experience perinatal mood disorders, with consequences to parenting ability, bonding with the neonate, interpersonal relationships, and health and well-being of parents. Research shows that maternal and paternal perinatal mood disorders are associated, but no recent systematic review has addressed the prevalence of perinatal mood disorders in both mothers and fathers (parental dyad).

OBJECTIVE: To examine the prevalence of perinatal mood disorders in parental dyads and identify factors associated with perinatal mood disorders in parental dyads.

DATA SOURCES: Ovid (MEDLINE, Embase, and PsycINFO) and Web of Science were searched from January 1, 1990, to June 8, 2021, for observational studies reporting on the prevalence of perinatal depression or anxiety in a parental dyad.

STUDY SELECTION: Studies reporting the prevalence of anxiety or depression in both members of a parental dyad were included, with diagnosis according to established criteria (Diagnostic and Statistical Manual of Mental Disorders [Fifth Edition], International Classification of Diseases, 11th Revision) or use of validated screening tools.

DATA EXTRACTION AND SYNTHESIS: Prevalence data were extracted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Data were analyzed in subgroups: antenatal depression, early postnatal depression (0-12 weeks), late postnatal depression (3-12 months), and perinatal anxiety. Pooled prevalence was calculated using a random-effects meta-analysis model. Quality assessment was performed using Joanna Briggs Institute Appraisal Checklist for Studies Reporting Prevalence Data. Data were analyzed in June 2021.

MAIN OUTCOMES AND MEASURES: Prevalence of perinatal anxiety and perinatal depression in parental dyads.

RESULTS: Twenty-three studies were included, with data from 29 286 couples. The pooled prevalence of antenatal depression in both parents was 1.72% (95% CI, 0.96%-2.48%; P < .001). The prevalence of early postnatal depression (up to 12 weeks post partum) was 2.37% (95% CI, 1.66%-3.08%; P < .001) and the prevalence of late postnatal depression (3-12 months post partum) was 3.18% (95% CI, 2.3-4.05; P < .001). Only 3 studies reported on perinatal anxiety in both parents, precluding a quantitative analysis.

CONCLUSIONS AND RELEVANCE: In up to 3.18% of couples, both parents may concurrently experience perinatal depression. Perinatal health care must consider the mental health needs of parents, both as individuals and as a parental dyad. Further research is needed to examine outcomes in families where both parents experience perinatal mood disorders.

ABSTRACT

The objective of this study was to evaluate the effect of feed restriction on some physical and blood parameters in horses kept outdoors under natural conditions. Twenty horses were deprived of food for 48 h. They were closely monitored and examined, and blood samples were taken at the beginning (0) of the experiment and 6, 12, 18, 24, 30, 36, 42 and 48 hours afterward. During the experimental period, the control group (12 animals) had free access to water and hay, while the restricted group had free access to water only. Data were submitted to two-way analysis of variance with repeated measures, and statistical significance was P ≤ 0.05. The horses tolerated feed restriction without complications. Feed restriction had no effect on body mass and body condition score, heart rate, respiratory rate, capillary filling time and body temperature. However, feed restriction decreased the intensity of gastrointestinal sounds (P<0.05) compared to the control horses. Feed restriction did not cause any changes in erythrocyte variables and gamma glutamyl transferase, creatinine, total protein, and albumin concentrations. During fasting, there was a reduction in the leukocyte response (P<0.05). Feed restriction significantly raised the levels of blood urea nitrogen (24 to 48 hours), aspartate aminotransferase (36 to 48 hours) and total cholesterol (42 to 48 hours). During 48 hours of fasting, there was a continuous increase in triglyceride concentration. Feed restriction for 48 h had a marked effect on the intensity of gastrointestinal sounds and was responsible for important metabolic changes in the healthy horses of our sample.

ABSTRACT

OBJECTIVE: The lack of information about the normal trend of the CRP blood levels in the post-operative days in gynecological benign surgery led us to start our study. We investigate the impact of different surgical techniques on the CRP trend. We carried on a comparative analysis between CRP trend and White Blood Cells (WBC) trend in postoperative monitoring.

METHODS: All of 207 participants were surgical patients for benign gynaecological pathology. We analized CRP and WBC levels after surgery on the total amount of women and separately by approaches.

RESULTS: CRP mean log-scores show a typical behavior. Moreover, the Chi-Square test result underlines that the proportion of women who report this behavior is independent from the type of surgery they had been undergone. Logscore mean values of CPR differ between any groups and between any times. No difference in mean of amount of white cells between the second and the third day was found, as observed for CRP.

CONCLUSION: Our study produced a trend reference model in post-operative monitoring of benign gynecological patients. The comparative analysis between CRP trend and WBC trend in post-operative days provided us data demonstrating the superiority of CRP in post-surgical patient outcomes monitoring.

ABSTRACT

INTRODUCTION: Despite their popularity in many EDs, little is known regarding perceptions of turkey sandwiches among patients. Given the importance of turkey sandwiches as a form of nutrition provided in EDs, we sought to quantify the composition and taste of ED turkey sandwiches through a quantitative assessment of turkey sandwiches by ED staff.

METHODS: This was a blinded observational study performed at a tertiary, urban academic medical center in Boston, MA. We collected ED turkey sandwiches up to 48 hours prior to study days from 4 emergency departments in the Boston area (2 community hospitals and 2 academic medical centers). We enrolled ED physicians, nurses, physician assistants, and staff who were exposed to four sandwiches in a random fashion. Participants were asked to assess sandwiches on a Likert scale of 1 to 5 on a variety of factors including, nutritional value “goodness”, smell “olfactory”, texture “bite”, ingredient distribution “balance”, appearance “look”, and flavor “edibility” to produce a composite score for sandwich quality (GOBBLE score). Next, participants were asked standardized questions surrounding suitability for consumption and nutrition on a 10 point Likert scale. We calculated mean scores and measured differences using t-tests.

RESULTS: We enrolled 22 participants over the study period. Twenty-one participants completed all measures. GOBBLE scores were calculated and averaged for sandwiches. A One-way ANOVA test was performed to measure statistically significant differences between mean GOBBLE scores (p<0.05) with a post hoc Tukey HSD procedure used to assess for statistically significant difference for pairwise comparison. A significant difference (p=0.009) was noted between the 4 sandwiches being compared, with a single site outperforming the others. Aggregating for academic and community sites demonstrated no statistically significant difference (p=0.08). Sandwiches in general were not considered healthy or palatable by study subjects.

CONCLUSION: Despite out-performance by a single ED, there is no significant difference in the quality of sandwiches provided to patients in EDs between academic and community hospitals. ED turkey sandwiches do not appear to be food items that are viewed as healthy or recommended to patients by ED staff who participated in this study.

ABSTRACT

Due to the scarcity of information on Breton horses, the objective was to study hematobiochemical values of this breed. Blood samples were collected from 29 Bretons, males and females, of different ages, in Brasília-DF, distributed into groups, according to age, without distinction of sex (G1): animals from 4 to 9 years old (n=16) and (G2): from 10 to 26 years old (n=13). The horses were also distributed into males and females for comparisons between the sexes. Values for red blood cells, hemoglobin, creatinine, and urea were statistically higher in females. Fibrinogen was higher in males. Lymphocyte values were higher in G1, but mean corpuscular volume, monocytes, neutrophils, and GGT in G2 were higher than G1. The hematocrit value differed between the ages of the females and was higher than that of the males, while the older male animals showed higher values than the young animals. Females presented lower platelet values than males, with older females having higher platelet values than younger females, in the same way as males. G1 females had the highest leukocyte values. The leukocyte values in males of G2 were higher than those of G1. This same behavior occurred for lymphocytes, eosinophils, and creatine kinase. Considering the albumin and aspartate aminotransferase variables, females had the highest values in the group of animals aged 4 to 9 years. Bretons are considered cold-blooded animals, which is consistent with the observed blood count values. However, it is concluded that these horses have biochemical values similar to warm-blooded breeds.

ABSTRACT

PURPOSE: To provide a method for determining the vector that, when added to the preoperative astigmatism, results in no prediction error (PE) and to specify statistical methods for evaluating astigmatism and determining the 95% confidence convex polygon.

SETTING: Baylor College of Medicine, Houston, Texas, and University of Southern California, Los Angeles, California.

DESIGN: Retrospective consecutive case series.

METHODS: An analysis of 3 clinical trials involving toric intraocular lenses was performed. 3 formulas were evaluated (generic vergence formula with zero surgically induced astigmatism, the Barrett toric formula, and the Holladay toric formula). Scalar and vector analyses were performed on each dataset with each formula and the results compared. Since the PE was not a Gaussian distribution, a 95% convex polygon was used to determine the spread of the data.

RESULTS: The mean values for the vector absolute astigmatism PEs were not different for the 3 formulas and 3 datasets. The Barrett and Holladay toric calculators were statistically superior to the zero formula for 3 intervals (0.75, 1.0, and 1.25) in the high astigmatism dataset.

CONCLUSIONS: Residual astigmatism and vector absolute astigmatism PE mean values and SDs are useful but require extremely large datasets to demonstrate a statistical difference, whereas examining percentages in 0.25 diopters (D) steps from 0.25 to 2.0 D reveals differences with far fewer cases using the McNemar test for a P value. Double-angle plots are especially useful to visualize astigmatic vector PEs, and a 95% confidence convex polygon should be used when distributions are not Gaussian.

ABSTRACT

COVID-19 is a systematic disease that frequently implies neurological and non-neurological manifestations, predominantly by inducing hypoxia. Brain-derived neurotrophic factor (BDNF) is a key factor in regulating functions of nervous and respiratory systems and has been strongly related to hypoxia. Therefore, this study planned to investigate BDNF association with the COVID-19 manifestations especially neurological impairments and the infection-induced hypoxia. We enrolled sixty-four COVID-19 patients and twenty-four healthy individuals in this study. Patients were divided into two groups, with and without neurological manifestations, and their serum BDNF levels were measured by enzyme-linked immunosorbent assay (ELISA). COVID-19 patients had significantly lower BDNF levels than healthy individuals (p = 0.023). BDNF levels were significantly lower in patients with neurological manifestations compared to healthy individuals (p = 0.010). However, we did not observe a statistically significant difference in BDNF levels between patients with and without neurological manifestations (p = 0.175). BDNF’s levels were significantly lower in patients with CNS manifestations (p = 0.039) and higher in patients with fever (p = 0.03) and dyspnea (p = 0.006). Secondly, BDNF levels have a significant negative association with oxygen therapy requirement (p = 0.015). These results strongly suggest the critical association between dysregulated BDNF and hypoxia in promoting COVID-19 manifestations, particularly neurological impairments.

ABSTRACT

INTRODUCTION: To compare surgical outcomes of 2.2 mm clear corneal incision (CCI) between a three-dimensional (3D) visualization system and traditional binocular microscope (BM) for phacoemulsification and intraocular lens implantation surgery.

METHODS: In this randomized controlled clinical study, 60 eyes with age-related cataracts were divided into two groups receiving cataract surgery using either a 3D vision system (n = 30 eyes) (3D group) or a binocular microscope (n = 30 eyes) (BM group). We recorded and statistically analyzed surgical parameters and pre- and postoperative ocular parameters. Primary outcomes included the change in endothelial cell density (ECD) and CCI architecture, and secondary outcomes comprised other ocular parameters and surgical parameters. All procedures complied with the tenets of the Declaration of Helsinki.

RESULTS: Of the 60 eyes randomly assigned between January 5, 2021, and May 9, 2021, 55 (26 eyes in the 3D group and 29 eyes in the BM group) were analyzed. The ECD loss rate was 8.1% in the 3D group and 12.3% in the BM group, but the difference was not statistically significant. Local detachment of Descemet’s membrane was seen in 50% (13 eyes, 3D group) and 51.6% (15 eyes, BM group), wound gaping at the endothelial side in 15.4% (four eyes, 3D group) and 10.3% (four eyes, BM group), gaping at the epithelial side in 11.5% (three eyes, 3D group) and 6.9% (two eyes, BM group), and misalignment of the incision in 3.4% (one eye, BM group) 1 day after surgery. These abnormalities improved with time. There was no difference between the 3D group and BM group in terms of other ocular parameters or surgical parameters before and after surgery.

CONCLUSIONS: Using the 3D surgical system for phacoemulsification and IOL implantation surgery seems to result in similar ECD and CCI conditions as using a conventional binocular microscope.

TRIAL REGISTRATION: The protocol was registered on ClinicalTrials.gov (NCT04839250).

ABSTRACT

For neuromorphic computing and high-density data storage memory, memristive devices have recently gained a lot of interest. So far, memristive devices have suffered from switching parameter instability, such as distortions in resistance values of low- and high-resistance states (LRSs and HRSs), dispersion in working voltage (set and reset voltages), and a small ratio of high and low resistance, among other issues. In this context, interface engineering is a critical technique for addressing the variation issues that obstruct the use of memristive devices. Herein, we engineered a high band gap, low Gibbs free energy Al₂O₃ interlayer between the HfO₂ switching layer and the tantalum oxy-nitride electrode (TaN) bottom electrode to operate as an oxygen reservoir, increasing the resistance ratio between HRS and LRS and enabling multilayer data storage. The Pt/HfO₂/Al₂O₃/TaN memristive device demonstrates analog bipolar resistive switching behavior with a potential ratio of HRS and LRS of > 10⁵ and the ability to store multi-level data with consistent retention and uniformity. On set and reset voltages, statistical analysis is used; the mean values (µ) of set and reset voltages are determined to be – 2.7 V and + 1.9 V, respectively. There is a repeatable durability over DC 1000 cycles, 10⁵ AC cycles, and a retention time of 10⁴ s at room temperature. Quantum conductance was obtained by increasing the reset voltage with step of 0.005 V with delay time of 0.1 s. Memristive device has also displayed synaptic properties like as potentiation/depression and paired-pulse facilitation (PPF). Results show that engineering of interlayer is an effective approach to improve the uniformity, ratio of high and low resistance, and multiple conductance quantization states and paves the way for research into neuromorphic synapses.

ABSTRACT

Orofacial cleft (OFC) is one of the most common congenital defects, with worldwide cases occurring in approximately 1:700 to 1:1000 births. This incidence is among the highest birth defects in Indonesia, and the incidence rate in Bandung Regency (14.69%) is the second-highest in West Java province. The purpose of this study was to analyze the association of heavy metal factors that accumulate in infants to the risk of OFC in Bandung Regency. The method was used by testing heavy metals Hg, Pb, Cd, Co, and Cr in infant blood. The total sample were 54 samples, where the case respondent of 32 and 22 respondents as the control group. Blood samples were analyzed using ICP-MS Agilent 7900. The correlation using statistic analyze namely chi-square analysis (bivariate) and multiple logistic regression (multivariate). The results showed that there was a significant difference in the concentration of heavy metals Hg, Pb, and Cd as well as an increase in Pb and Cd in the infant’s blood which was thought to be significantly associated with the risk of OFC.
