Distribution of uterocervical angles of pregnant women at 16+ 0 to 23+ 6 weeks gestation with low risk for preterm birth: first vietnamese cohort of women with singleton pregnancies

BMC Pregnancy Childbirth. 2023 Apr 28;23(1):301. doi: 10.1186/s12884-023-05597-3.

ABSTRACT

BACKGROUND: Cervical length (CL) measured by ultrasound in the second trimester is a predictor of spontaneous preterm birth (sPTB). The uterocervical angle (UCA) has recently been suggested as a predictor to identify women at risk of sPTB. The aim of this study was to investigate the UCAs’ distribution in singleton pregnant women at 16+ 0 – 23+ 6 weeks of gestation with low risk for sPTB.

METHODS: This was a prospective cohort study of 1,051 pregnant women with singleton pregnancies at low risk for preterm delivery. Pregnant women with a viable singleton fetus at 16+ 0 – 23+ 6 weeks of gestation were enrolled in the study conducted at the Haiphong Hospital of Obstetrics and Gynecology, Vietnam, from 09/2019 to 09/2020. CL and the UCA were assessed using transvaginal ultrasonography (TVS) by a single sonographer. Subjects were followed-up until the end of pregnancy, and maternal and neonatal outcomes were recorded. The UCAs’ range and their relationship with gestational age were evaluated using regression analysis. P < 0.05 was considered statistically significant.

RESULTS: The normal range of the UCA (5th – 95th percentiles) was 46.47° (95% CI, 40.27°-51.81°) to 127.06° (95% CI, 123.02° – 130.71°). The UCAs in the preterm birth (< 37 weeks) and full-term groups were 117.86° ± 20.25° and 83.80° ± 24.18°, respectively (p < 0.001). Linear regression analysis showed a significant change in the UCA range from 16+ 0 to 23+ 6 weeks of gestation (2.51 degrees per week, p < 0.001). The linear function yielded the highest correlation coefficient in the variation rule of the UCA values (r = 0.22). A total of 42/63 (66.7%) patients with preterm birth < 37 weeks had a UCA above the 75th percentile. The majority of women with preterm birth had a UCA ≥ 95° compared with those with full-term delivery (88.9% vs. 31.3%, p < 0.001).

CONCLUSIONS: The results of this study present background information about the normal range of UCA values in singleton pregnant women at 16+ 0 to 23+ 6 weeks at low risk for sPTB in this Vietnamese cohort. In this study population at low risk for sPTB, pregnant women with a UCA value ≥ 95o were also considered at risk for preterm birth.

Reliability of prostate imaging reporting and data system version 2.1 for excluding clinically significant prostate cancer using a 1.5 tesla scanner

BMC Urol. 2023 Apr 28;23(1):69. doi: 10.1186/s12894-023-01241-6.

ABSTRACT

INTRODUCTION: Multiparametric magnetic resonance imaging (mpMRI) of the prostate gland is now the recommended initial investigation of choice for the detection of Prostate cancer (PCa). It effectively identifies patients who require prostate biopsies due to the risk of clinically significant PCa. It helps patients with clinically insignificant PCa avoid the invasive biopsies and possible accompanying complications. Large clinical trials have investigated the accuracy of mpMRI in detecting PCa. We performed a local review to examine the reliability of omitting tissue sampling in men with a negative (PIRADS 2 (P2) or less) mpMRI in the primary diagnostic setting.

METHODS: This was a retrospective study of patients with clinical suspicion of PCa within a 2-year period. Patients had a mpMRI prior to having trans-perineal prostate gland biopsies. Clinically significant disease was defined as Gleason 7 and above. The descriptive data was analysed using contingency table methods. A p-value less than 0.05 was statistically significant.

RESULTS: Out of 700 patients 90 had an mpMRI score of PIRADS 2. Seventy-seven (85.5%) of these patients had a negative biopsy, 9(10%) showed Gleason 6, 4 patients showed Gleason 7 or above. 78 patients with PIRADS 2 had a PSA density of < 0.15, none of which had a clinically significant biopsy result. The negative predictive value of mpMRI from this study is 95%.

CONCLUSION: Our results are in line with negative predictive values demonstrated in the current literature. This local study, likely applicable to other district general hospitals, shows that mpMRI is a safe and reliable initial investigation to aid decisions on which patients require biopsies.

Can regulatory T cells improve outcomes of sensitised patients after HLA-Ab incompatible renal transplantation: study protocol for the Phase IIa GAMECHANgER-1 trial

BMC Nephrol. 2023 Apr 28;24(1):117. doi: 10.1186/s12882-023-03157-7.

ABSTRACT

BACKGROUND: Kidney transplantation is the gold-standard treatment for patients with kidney failure. However, one-third of patients awaiting a kidney transplant are highly sensitized to human leukocyte antigens (HLA), resulting in an increased waiting time for a suitable kidney, more acute and chronic rejection, and a shorter graft survival compared to non-highly sensitised patients. Current standard immunosuppression protocols do not adequately suppress memory responses, and so alternative strategies are needed. Autologous polyclonally expanded regulatory T cells (Tregs) have been demonstrated to be safe in transplant settings and could be a potential alternative to modulate memory immune alloresponses.

METHODS: The aim of this trial is to determine whether adoptive transfer of autologous Tregs into HLA sensitised patients can suppress memory T and B cell responses against specific HLA antigens. This is a two-part, multi-centre, prospective clinical trial, comprising an observational phase (Part 1) aiming to identify patients with unregulated cellular memory responses to HLA (Pure HLA Proteins) followed by an interventional phase (Part 2). The first 9 patients identified as being eligible in Part 1 will undergo baseline immune monitoring for 2 months to inform statistical analysis of the primary endpoint. Part 2 is an adaptive, open labelled trial based on Simon’s two-stage design, with 21 patients receiving Good Manufacturing Practice (GMP)-grade polyclonally expanded Tregs to a dose of 5-10 × 106 cells/kg body weight. The primary EP is suppression of in vitro memory responses for 2 months post-infusion. 12 patients will receive treatment in stage 1 of Part 2, and 9 patients will receive treatment in stage 2 of Part 2 if ≥ 50% patients pass the primary EP in stage 1.

DISCUSSION: This is a prospective study aiming to identify patients with unregulated cellular memory responses to Pure HLA Proteins and determine baseline variation in these patterns of response. Part 2 will be an adaptive phase IIa clinical trial with 21 patients receiving a single infusion of GMP-grade polyclonally expanded Tregs in two stages. It remains to be demonstrated that modulating memory alloresponses clinically using Treg therapy is achievable.

TRIAL REGISTRATION: EudraCT Number: 2021-001,664-23. REC Number: 21/SC/0253. Trial registration number ISRCTN14582152.

Surgical treatment of rare pediatric cardiac myxomas:12 years clinical experience in a single institution

BMC Cardiovasc Disord. 2023 Apr 28;23(1):219. doi: 10.1186/s12872-023-03255-2.

ABSTRACT

BACKGROUND: Primary cardiac tumors are rare, and cardiac myxoma (CM) accounts for the majority of these tumors. Most of the reports in the literature are case reports. This study summarizes our clinical experience in the surgical treatment of CM over the past 12 years.

METHODS: We retrospectively analyzed the clinical data of 23 children with CM(8 boys, 15 girls; median age: 8.92 months, range: 2 years 5 months-12 years 9 months; body weight: 11-45 kg, median body weight: 28.21 kg) admitted to our hospital in the previous 12 years, and we statistically analyzed their clinical manifestations and surgical methods.

RESULTS: 23 cases underwent myxoma excision under cardiopulmonary bypass(CPB). The follow-up period was 0.2 to 12.6 years (mean:7.2 years). Two patients could not be traced, and the follow-up completion rate was 91.30%. One patient (4.35%) died of myocardial infarction early after surgery with low continuous cardiac output. There were no cerebral embolism, acute heart failure, atrioventricular block and other related complications in 19 cases. A patient with cerebral infarction complicated with right hemiplegia recovered well after rehabilitation treatment. There was no recurrence of CM in 19 cases and all patients recovered after surgery. One patient relapsed 5 years after surgery, and no tumor recurrence was observed after the second surgery. Among the 20 long-term survivors, 13 (65.00%) were NYHA Class I patients and 7(35.00%) were NYHA Class II patients.

CONCLUSIONS: Although CM in children is rare, it may cause cerebral infarction and other multi-organ embolism. Once CM is found and removed as soon as possible, it can reduce serious complications. If the complete resection is possible, surgery provides better palliation. Follow-up echocardiographic should be paid attention to after surgery.

Telepractice in the diagnosis and treatment of pediatric speech-language disorders: The opinions and experiences of speech-language pathologists

Int J Pediatr Otorhinolaryngol. 2023 Apr 19;169:111560. doi: 10.1016/j.ijporl.2023.111560. Online ahead of print.

ABSTRACT

PURPOSE: This prospective cross-sectional study aimed to investigate the opinions and experiences with telepractice (TP) of Dutch-speaking speech-language pathologists (SLPs) living in the Dutch-speaking part of Belgium (Flanders). This study will help to optimize care for children with speech-language disorders as we will gain more insight into the experienced barriers and facilitators while using TP for assessing and treating these disorders.

METHOD: Twenty-nine Dutch-speaking speech-language pathologists living in Flanders (age category 20-30 years: n = 16/29, 55.2%, 31-40 years: n = 10/29, 34.2%, 41-50 years: n = 2/29, 6.9%, 51-60 years: n = 1/29, 3.4%) were recruited through the social media. An online questionnaire was developed based on the available literature and administered to the SLPs. To compare the opinions and experiences of SLPs with TP, χ2 tests or Fisher’s exact tests were used.

RESULTS: The study showed a statistically significant association between years of clinical experience of SLPs and their opinion that TP does not provide more options in a clinical setting compared to face-to-face contact. SLPs who had expertise in multiple domains experienced significantly more added value of TP during the corona pandemic than SLPs who had expertise in only one specific domain. Additionally, SLPs who worked in a private practice indicated significantly more difficulties in developing a therapeutic relationship due to a lack of personal contact than SLPs who worked in other settings. 51.7% (15/29) of the SLPs experienced technical barriers using TP.

CONCLUSION: Expertise in multiple domains of pediatric speech-language therapy resulted in experiencing more added value of TP during the corona pandemic, possibly because of the experience of multiple different and simultaneous advantages of TP in several domains. Additionally, SLPs in a private practice experienced more difficulties in developing a therapeutic relationship due to a lack of personal contact with their clients. This is in contrast to hospitals where children are often seen for a shorter period. Hence, there may be less chance of a negative perception of relationships with clients. Another conclusion is that treatment drop-out was not larger using TP compared to face-to-face therapy. However, SLPs experienced that the use of TP was not promoted/encouraged by their employer possibly because of technical barriers. It is hoped that the findings of this study will help SLPs and policymakers overthrow existing barriers and make telepractice a substantial, effective, and efficient service delivery model.

CT characterization of retractor related liver injuries after pancreaticoduodenectomy: Retrospective analysis of a single institution experience

Clin Imaging. 2023 Apr 18;99:53-59. doi: 10.1016/j.clinimag.2023.04.006. Online ahead of print.

ABSTRACT

PURPOSE: Retractor related liver injuries (RRLI) are reported after upper gastrointestinal tract surgeries; most commonly laparoscopic cholecystectomy and gastric surgeries. The aim of this study was to characterize the incidence, identification, type, severity, clinical features and risk factors for RRLI after open and robotic pancreaticoduodenectomy.

METHODS: A 6-year retrospective study of 230 patients was performed. Clinical data was extracted from the electronic medical record. Post-operative imaging was reviewed and graded using the American Association for the Surgery of Trauma (AAST) liver injury scale.

RESULTS: 109 patients met eligibility criteria. RRLI occurred in 23/109 (21.1%), with a higher incidence in the robotic/combinedapproach (4/9) compared with open (19/100). Most common injury was an intraparenchymal hematoma (56.5%), grade II (78.3%), located in segments II/III (77%). 39.1% of injuries were not reported on the CT interpretation. There was a statistically significant elevation of postoperative AST/ALT in the RRLI group [median AST 219.5 vs. 72.0 (p < 0.001), ALT 203.0 vs. 69.0 (p < 0.001)]. Trends toward lower preoperative platelet counts and longer operations were observed in the RRLI group. No significant difference in hospital length of stay or post-operative pain scores were noted.

CONCLUSION: RRLI occurred frequently after pancreaticoduodenectomy, however most injuries were low grade and the only clinical significance was a transient increase in transaminases. A trend toward higher injury rates was observed in robotic cases. In this population, RRLI was often unrecognized on postoperative imaging.

Investigation of low and high dose rate X-ray effects on histopathological changes and prognostic importance of Ki-67 in laryngeal cancer radiotherapy

Appl Radiat Isot. 2023 Apr 17;197:110823. doi: 10.1016/j.apradiso.2023.110823. Online ahead of print.

ABSTRACT

The aim of this study is to analyze the effect on histopathological changes and Ki-67 expression levels of Flattening Filter (FF) and Flattening Filter Free (FFF) beams to investigate the radiobiological mechanisms underlying laryngeal cancer (LCa) post-radiotherapy (RT) on mice models. Forty adult NOD SCID gamma (NSG) mice models were randomly divided into four groups; the sham, LCa, FF-RT and FFF-RT groups. The head and neck region of mice in FF-RT and FFF-RT groups (LCa plus RT groups) were irradiated with a single dose of 18 Gy at 400 MU/min and 1400 MU/min. The NSG mice received radiotherapy 30 days after tumor transplantation and sacrificed 2 days after radiotherapy for analysis of histopathology parameters and K-67 expression levels. Comparing the LCa, FF-RT and FFF-RT groups with the sham group, statistically significant differences were observed in histopathological parameters depending on tumor tissue and dose rate (p < 0.05). When the histopathological effects of FF-RT beam on LCa tissue were compared with FFF-RT beam, it was observed that statistically significant differences occurred (p < 0.05). Comparing the LCa group with the sham group, it was observed that the Ki-67 level affected significantly depending on the development of cancer (p < 0.01). It was concluded that FF and FFF beams caused significant changes in the histopathological parameters and Ki-67 expression levels. When the effects of FFF beam on Ki-67 levels, cell nucleus and cytoplasmic findings were compared with FF beam, significant radiobiological differences were observed.

The stability of personality disorders and personality disorder criteria: A systematic review and meta-analysis

Clin Psychol Rev. 2023 Apr 23;102:102284. doi: 10.1016/j.cpr.2023.102284. Online ahead of print.

ABSTRACT

The aim of this systematic review and meta-analysis was to investigate the diagnostic, the dimensional mean-level, and rank-order stability of personality disorders (PDs) and PD criteria over time. EMBASE, PsycInfo, PubMed, and Web of Science were searched for peer-reviewed studies published in either English, German, or French between the first publication of the third edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III) in 1980 and December 20, 2022. Inclusion criteria were a prospective longitudinal study design, assessing the stability of PDs or PD criteria over at least two measurement occasions at least one month apart, and using the same assessment at baseline and follow-up. Effect sizes included proportion of enduring cases (i.e., diagnostic stability), test-retest correlations (i.e., dimensional rank-order stability), and within-group standardized mean differences (i.e., dimensional mean-level stability), based on the first and last available measurement occasion. From an initial pool of 1473 studies, 40 were included in our analyses, covering 38,432 participants. 56.7% maintained the diagnosis of any PD, and 45.2% maintained the diagnosis of borderline PD over time. Findings on the dimensional mean-level stability indicate that most PD criteria significantly decreased from baseline to follow-up, except for antisocial, obsessive-compulsive, and schizoid PD criteria. Findings on the dimensional rank-order stability suggested moderate estimates, except for antisocial PD criteria, which were found to be high. Findings indicated that both PDs and PD criteria were only moderately stable, although between study heterogeneity was high, and stability itself depended on several methodological factors.

Air pollution exposure and social responsiveness in childhood: The cincinnati combined childhood cohorts

Int J Hyg Environ Health. 2023 Apr 26;251:114172. doi: 10.1016/j.ijheh.2023.114172. Online ahead of print.

ABSTRACT

Autism Spectrum Disorder (ASD) affects about 1 in 44 children and environmental exposures may contribute to disease onset. Air pollution has been associated with adverse neurobehavioral outcomes, yet little research has examined its association with autistic-like behaviors. Therefore, our objective was to examine the association between exposure to air pollution, including NO2 and PM2.5, during pregnancy and the first year of life to ASD-like behaviors during childhood. Participants (n = 435) enrolled in the Cincinnati Childhood Allergy and Air Pollution Study and the Health Outcomes and Measures of the Environment Study were included in the analysis. Daily exposures to NO2 and PM2.5 at the residential addresses of participants were estimated using validated spatiotemporal models and averaged to obtain prenatal and first year exposure estimates. ASD-like behaviors were assessed via the Social Responsiveness Scale (SRS) questionnaire at age 12. Linear regression models adjusting for confounders were applied to estimate the association between pollutants and SRS scores. After adjusting for covariates, the association between NO2 and PM2.5 and SRS scores remained positive but were no longer statistically significant. Prenatal and first year exposure to NO2 were associated with total SRS T-scores with an estimated 0.4 point increase (95% CI: -0.7, 1.6) per 5.2 ppb increase in NO2 exposure and 0.7 point (95% CI: -0.3, 1.6) per 4.2 ppb increase in NO2 exposure, respectively. For PM2.5, a 2.6 μg/m3 increase in prenatal exposure was associated with a 0.1 point increase (95% CI: -1.1, 1.4) in SRS Total T-scores and a 1.3 μg/m3 increase first year of life was associated with a 1 point increase (95% CI: -0.2, 2.3). In summary, exposure to NO2 and PM2.5 during pregnancy and the first year of life were not significantly associated with higher autistic-like behaviors measured with SRS scores after adjustment of covariates. Additional research is warranted given prior studies suggesting air pollution contributes to ASD.

Usual source and better quality of primary care are associated with lower loneliness scores: a cross-sectional study

Fam Pract. 2023 Apr 28:cmad049. doi: 10.1093/fampra/cmad049. Online ahead of print.

ABSTRACT

BACKGROUND: Loneliness is a global issue, and primary care physicians play an important role in assessing and intervening with loneliness. This study aimed to examine the association between having a usual source of care (USC) or a good quality of primary care, and loneliness.

METHODS: This cross-sectional study was conducted in Japan in 2022. A total of 6,000 residents were randomly sampled from the general population, aged 20-74 years. The outcome was the total score of the University of California, Los Angeles (UCLA) 3-item loneliness scale. The exposure included USC and the Person-Centered Primary Care Measure (PCPCM), which assesses the quality of primary care. We conducted a linear regression analysis to adjust for age, sex, educational status, annual household income, self-rated health, living status (whether alone or not), and the existence of physical health problems.

RESULTS: Of the 6,000 residents, 1,277 responded to the survey. The median score of the UCLA 3-item loneliness scale was 6.0 and the mean total score of the PCPCM was 2.62. Of the 1,277 individuals, 713 (55.8%) had USC. Having USC was significantly associated with lower scores on the UCLA 3-item loneliness scale; the coefficient was -0.34 (95% confidence interval (CI): -0.57 to -0.12). Also, the total PCPCM score was significantly associated with lower loneliness scores; the coefficient was -0.56 (P < 0.001, 95% CI: -0.78 to -0.35).

CONCLUSIONS: Having USC and a better quality primary care were associated with a lower loneliness score. The quality of primary care could be a factor to mitigate patient loneliness.
