Effect of porcine placental extract on menopausal symptoms in postmenopausal women: A prospective,randomized, double-blind,placebo-controlled trial

ObjectivesTo determine the effect of oral administration of porcine placental extract (PPE) on the menopausal symptoms of Korean women.Materials and methodsThis study was a multicenter, randomized double-blind placebo-controlled trial. A hundred menopausal Korean women were randomly allocated either to the PPE 400 mg per day or the control group during 12 weeks of the study period. Menopausal symptoms were evaluated using the Kupperman Index (KMI).ResultsThe KMI decreased after 12 weeks in both groups; however, the difference in the changes was not statistically significant. Among overweight or obese women whose body mass index (BMI) was 23 kg/m² or higher, the KMI decreased more significantly in the PPE group than placebo group after 12 weeks (−18.52 ± 9.09 vs −11.40 ± 10.68, P < 0.05). Among 49 early menopausal women whose duration of menopause was less than 3 years, the KMI decreased more significantly in the PPE group after 12 weeks (−17.29 ± 9.07 vs −11.29 ± 10.68, P < 0.05). The baseline estradiol level was not statistically different between the two groups before trial, but the estradiol level of the PPE group was significantly increased at 12 weeks (11.13 ± 35.13 pg/m, P < 0.05).ConclusionsOral administration of 400 mg PPE per day decreases menopausal symptoms in women with BMI 23 kg/m² or higher or in early menopausal women. PPE may be considered as a short-term complementary treatment to reduce menopausal symptoms, especially in overweight or early menopausal women.     

Effects of pomegranate supplement on menopausal symptoms and quality of life in menopausal women: A double-blind randomized placebo-controlled trial

BackgroundMenopausal symptoms have negative effects on the aspects of quality of life and impose a high cost on the health system. In traditional Persian medicine, pomegranate is recommended to alleviate menopausal symptoms.Material and methodsA randomized double-blind placebo-controlled trial was performed among 78 healthy women. Participants were interviewed three times: Before receiving the supplement/placebo, after completing the treatment, and after 3 weeks with no intervention. They filled out the demographic information sheet, modified-Kupperman index, and Menopause-Specific Quality of Life (MENQOL) questionnaires.ResultsThe mean scores of the modified-Kupperman index and MENQOL characteristics before and after the treatment and after the follow-up period were significantly different between pomegranate and placebo groups in both modified-Kupperman and MENQOL scores (p < 0.001).ConclusionThis study demonstrated that 4 weeks' treatment with the pomegranate supplement significantly ameliorates the irritating symptoms of menopause and improves the quality of life in menopausal women even after 4 weeks' medicine deprivation.     

Efficacy and safety of Buyang-Huanwu-Tang (Boyang-Hwano-Tang) in patients with vascular dementia: A systematic review and meta-analysis

BackgroundBuyang-Huanwu-Tang (Boyang-Hwano-Tang, BHT) is a widely used traditional Chinese herbal medicine for treating ischemic stroke in South Korea and China. Its efficacy in vascular dementia has been reported. There has been no comprehensive systematic review of BHT for vascular dementia.MethodsWe searched 15 electronic databases from inception to November 25, 2021. We included only randomised controlled clinical trials. Studies that used BHT alone or with Western medicine were included. Two independent reviewers conducted the screening, data extraction, and the Cochrane risk of bias and quality of evidence assessment. A meta-analysis was performed.ResultsA total of 18 eligible trials with 1254 participants were included. Of these, 15 were included in the meta-analysis. The pooled results suggested that BHT alone (mean difference [MD] 1.31; 95% confidence interval [CI] −2.94 to 5.56; P = 0.55) was similar to Western medicine alone in terms of the Mini-Mental State Examination(MMSE). Additive BHT therapy showed a significant improvement in the MMSE (MD 1.42; 95% CI 0.28 to 2.56; P = 0.01), Hasegawa Dementia Scale score (MD 3.91; 95% CI 2.87 to 4.94; P < 0.001) and total effective rate (risk ratio 1.35; 95% CI 1.20 to 1.52; P < 0.001). The overall risk of bias was unclear or high. The quality of evidence was very low to moderate. Only four studies reported minor or no adverse events.ConclusionsThe results support the clinical use of BHT for the improvement of cognitive function in patients with vascular dementia. The methodological quality of the included studies was relatively poor. Therefore, further rigorously designed trials are required.     

Meta analysis for insomnia Guizhi Gancao Longgu Muli decoction for insomnia A meta-analysis

BackgroundGuizhi Gancao Longgu Muli Decoction can make a good effect on the insomnia under the catalogue of traditional Chinese medicine.MethodTo search the databases:Pubmed, Web of Science, EMBASE, the Cochrane Library, the China National Knowledge Infrastructure (CNKI), the China Biology Medicine disc (CBMdisc), the China Science and Technology Journal Database (VIP), the Wanfang.ResultsFifteen randomized controlled trials were included, totally including 1164 participants. After summarizing the observational index revised according to the “Guiding Principles for Clinical Research of New Chinese Medicines”, we found that the curative effect of the trial group is 2.29 times that of the control group in the fixed effect model which had a statistically significant difference [OR = 2.293681, 95%CI = 0.3266112–5.83]. And the Pittsburgh Sleep Quality Index (PSQI) which had 7 different dimensions, including subjective sleep quality[p = 0.001 < 0.05], sleep latency, sleep duration[p = 0.000 < 0.05], habitual SE[p = 0.000 < 0.05], sleep disorders[p = 0.002 < 0.05], use of sleep medications[p = 0.000 < 0.05], and daytime dysfunction[p = 0.000 < 0.05], showed a higher scores in the trial group than the one in the control group in every dimension. The final results of the total scores in PSQI also showed a higher scores in trial group with a p = 0.000 < 0.05 (Test of WMD), suggest a statistically significant difference. While the adverse effects showed a lower rate in the trial group than the one in the control group under a fixed-effect model, with a p = 0.000 < 0.05, indicate a statistically significant difference.ConclusionThe efficacy and safety of GGLMD in the trial groups are better than the modern western medicine in the control groups.     

Restoring tubal patency with laparoscopic tubocornual anastomosis

ObjectiveTo assess the technical feasibility of laparoscopic tubocornual anastomosis (TCA) at restoring tubal patency in patients with proximal tubal occlusions.Materials and methodsA retrospective analysis of fourteen females with identified proximal tubal occlusions seeking to restore their tubal patency in a university-affiliated tertiary hospital between 2011 and 2018. Tubal patency within one year after the surgery was evaluated.ResultsThe patients had a mean age of 34.0 ± 3.6 years old, median parity of 1 child, and mean BMI of 23.0 ± 5.2 kg/m². Of the fourteen patients, two (14.3%) received bilateral TCA, eight (57.1%) received only unilateral TCA, and four (28.6%) received TCA on one side and tubal anastomosis on the other. The operative time was 126.4 ± 37.9min for unilateral procedure and 201.0 ± 1.4 min for bilateral anastomoses. Postoperative hysterosalpingogram (HSG) demonstrated a patency rate of 64.2% at the TCA sites. Two ectopic pregnancies were reported thereafter.ConclusionThis preliminary series demonstrates that laparoscopic TCA is technically feasible and provides promising results for patients with proximal tubal occlusions hoping to restore their tubal function in order to conceive naturally. A larger prospective series is mandatory to establish its significance and application in clinical practices. Notably, infertile patients without surgically correctable factors are not suitable for this procedure.     

Acute chorioamnionitis and intra-amniotic inflammation are more severe according to outside-in neutrophil migration within the same chorio-decidua

ObjectiveNo information exists about whether acute histologic chorioamnionitis (acute-HCA) is more advanced and severe, and intra-amniotic inflammation is more frequent and intense according to outside in neutrophil migration within the same chorio-decidua. The objective of current study is to examine this issue.Materials and methodsWe included 106 singleton preterm-births (gestational age at delivery: 20–34 weeks) due to either preterm-labor or preterm-PROM in the context of acute chorio-deciduitis. Study-population was divided into 3 groups according to outside-in neutrophil migration within chorio-decidua as follows: 1) group-1: ‘inflammation restricted to the decidua’ (n = 22); 2) group-2: ‘inflammation restricted to the MT of chorion and the decidua’ (n = 31); 3) group-3: ‘inflammation in the CT of chorion’ (n = 53). We examined the frequency of inflammation in each placental compartment beyond chorio-decidua (i.e., amnion, umbilical cord, and chorionic-plate), and total grade (1–8) of acute-HCA. Moreover, the frequency of intra-amniotic infection (defined as positive amniotic-fluid culture for aerobic and anaerobic bacteria and genital mycoplasmas) and intra-amniotic inflammation (defined as amniotic fluid WBC ≥ 19 cells/mm³), and an intra-amniotic inflammatory response gauged by amnioticfluid WBC count (cells/mm³) were examined in 50 amniotic fluid samples within 7 days of birth.ResultsAmnionitis, funisitis and chorionic plate inflammation were more frequent (each for P < 0.01) and median total grade of acute-HCA was increased (P < 0.001) according to outside-in neutrophil migration within chorio-decidua (group-1vs.group-2vs.group-3). Moreover, intra-amniotic infection and inflammation were more frequent (each-for P < 0.05) and median amniotic-fluid WBC count was increased (P < 0.01) according-to outside-in neutrophil-migration within chorio-decidua (group-1 vs. group-2 vs. group-3).ConclusionAcute-HCA is more advanced and severe, and intra-amniotic inflammation is more frequent and intense according to outside in neutrophil migration within the same chorio-decidua. This finding suggests that what is now acute chorio-deciduitis should be subdivided.     

Characterizing the Adolescent Premature Ovarian Insufficiency Phenotype: A Case Control Study

Study ObjectivesTo characterize the skeletal, cardiometabolic, cognitive, and mental health phenotype of adolescents with idiopathic premature ovarian insufficiency (POI)DesignCase controlSettingPediatric tertiary referral center in Cincinnati, OhioParticipantsNine adolescents (ages 11-18.99 years) with newly diagnosed POI and 9 normally menstruating controls, matched by age and body mass indexMain Outcome MeasuresBetween-group comparisons of bone characteristics assessed by dual energy x-ray absorptiometry (DXA) and peripheral quantitative computed tomography (pQCT), psychosocial health (anxiety, depression, and quality of life), and cognition and memory by questionnaireResultsAdolescents with POI had lower bone density Z-scores by DXA (lumbar spine −1.93 vs 0.80; whole body less head −2.05 vs 0.00; total hip −1.03 vs 0.83; and femoral neck −1.23 vs 0.91; all P < .001), as well as lower trabecular volumetric bone mineral density (tibia 3% site 226 vs 288 mg/mm³, P < .001; radius 3% site 200 vs 251, P = .001), smaller cortical area (tibia 66% site 251 vs 292 mm², P = .028), and thickness (tibia 66% site 3.56 vs 4.30 mm, P = .001) than controls. No abnormalities in cardiometabolic biomarkers were detected in POI cases. Adolescents with POI were also more likely to report low energy (78% vs 22%, P = .02).ConclusionEstrogen deficiency adversely affects bone health in adolescents with POI. However, we did not find associations with cardiometabolic, mental health, or cognitive outcomes in this small sample.     

Pulmonary rehabilitation in subterranean chambers combined with neuro-orthopedic activity-dependent plasticity therapy influences patients’ quality of life – A preliminary study

ObjectiveThe aim of the study was to evaluate if Neuro-orthopedic Activity-dependent Plasticity (N.A.P.) therapy combined with standard subterranean pulmonary rehabilitation (SPR) conducted in the salt mine influences the health-related quality of life (HRQoL) and chest mobility in patients with asthma or chronic upper respiratory tracts diseases.Methods54 patients enrolled for the study completed a 3-week SPR. The 15D questionnaire, chest mobility and back scratch flexibility tests were conducted before and after SPR. In the study group (N = 23,16 women, 7 men) the N.A.P. therapy was added to SPR, while the control group (N = 31, 21 women and 10 men) completed the SPR program.ResultsAfter the SPR statistically significant improvements were observed on the 15D dimensions of breathing and vitality dimensions, in the chest mobility and back flexibility in both groups.With the baseline gender distribution, age, generic 15D score, chest mobility and back scratch adjusted, the change in the 15D score was 0.068 greater in the study group than in the control group. This difference is clinically important and statistically significant (p = 0.022). There was no statistically significant difference in the chest mobility and back scratch flexibility between the groups.ConclusionsAdding N.A.P. therapy techniques to the SPR program in the underground part of the ‘Wieliczka’ Salt Mine Health Resort results in a statistically significant and clinically important improvement in the subjects' HRQoL.     

Maternal blood concentration of tadalafil in pregnancy: Comparison of pregnant and non-pregnant women

ObjectiveIn this study, the drug kinetics of tadalafil were compared between pregnant and non-pregnant women to determine the ideal dosage to promote uterine blood flow.Materials and methodsWe recruited five pregnant and five non-pregnant women, all of which were administered tadalafil (20 mg/day). The blood concentration of tadalafil was measured 1, 2, 4, 6, 8, and 24 h after administration. We investigated the side effects within 4 days of tadalafil administration and compared the cumulative frequency between the two groups.ResultsThe mean area under the concentration–time curve and maximum blood concentration of tadalafil were not different between the pregnant and non-pregnant groups. Time to maximum blood concentration was delayed by 1 min on average in the pregnant group compared with the non-pregnant group. The cumulative frequency of side effects was significantly lower in the pregnant group than in the non-pregnant group (P = 0.026). No side effects were observed in either group after the fifth day of the tadalafil administration.ConclusionAlthough there was no difference in maximum blood concentration between non-pregnant and pregnant women, the rate of side effects was lower in pregnant women than in non-pregnant women. Therefore, pregnant women may tolerate tadalafil better.     

A novel approach in the management of placenta accreta spectrum disorders: A single-center multidisciplinary surgical experience at Tu Du Hospital in Vietnam

ObjectivePlacenta accreta spectrum disorders (PASD) are the leading cause which results in highly maternal mortality during pregnancy. Although hysterectomy has been the gold standard for PASD, the recent study along with our experience has been demonstrated that the association between uterine myometrial resection and transverse B-Lynch suture in conservative management might be effective in the appropriate patients, thus we hereby attempted to determine this issue.Materials and methodsA retrospective observational study enrolled 65 patients at Tu Du Hospital in Vietnam between January 2017 and December 2018. This study included all pregnant women above 28 weeks of gestational age, who had undergone cesarean delivery due to PASD diagnosed preoperatively by ultrasound or upon laparotomy. Additionally, all patients who desired uterine preservation underwent modified one-step conservative uterine surgery (MOSCUS), avoiding peripartum hysterectomy.ResultsOverall, the rate of successful preservation was 93.8%. Other main outcomes such as average operative blood loss was 987 mL, mean blood transfusion was 831 ± 672 mL; mean operative time was 135 ± 31 min and average postoperative time was 5.79 days. Postoperative complications included six out of 65 cases due to intraoperative bleeding and postoperative infection, requiring hysterectomy in 4 patients.ConclusionMOSCUS was associated with less operative blood loss and blood transfusion amount. Its success rate of uterine preservation was approximately 94% in our study. Thus, this method can be acceptable in PASD management at our maternity health care center. Further studies might be necessary to evaluate the long-term effects of this method in PASD management.     

Bleeding-related outcomes of low-risk total placenta previa are equivalent to those of partial/marginal placenta previa

ObjectiveTo clarify whether “low-risk total PP” patients bleed more than partial/marginal PP patients.Materials and methodsThe retrospective cohort study was performed involving patients with PP between April 2006 and December 2018. The placental position was determined by ultrasound. From medical charts, the backgrounds as well as obstetric and neonatal outcomes of PP patients were retrieved.ResultsThis study included 349 patients with PP, which was classified into three types according to the distance between the placenta and internal ostium: total (n = 174), partial (n = 52), and marginal (n = 123) PP. In total PP patients, three factors (prior CS, anterior placenta, and placental lacunae on ultrasound) significantly increased blood loss at CS, the need for hysterectomy, homologous transfusion (≥10 U), and ICU admission. No significant difference was observed in bleeding-related poor outcomes (rate of blood loss ≥2000 mL, amount of homologous transfusion, need for hysterectomy, and ICU admission) between total PP patients without all three factors: “low-risk total PP patients” and partial/marginal PP patients (19.8 vs. 17.1%; p = 0.604, 3.7 vs. 1.1%; p = 0.330, 1.2 vs. 1.1%; p = 1.000, and 1.2 vs. 1.1%; p = 1.000, respectively).ConclusionPrior CS, anterior placenta, and placental lacunae on ultrasound were risk factors for a bleeding-related poor outcome in total PP patients. Total PP patients without these three factors showed the same bleeding-related poor outcome as partial/marginal PP patients.     

Creative versus repetitive dance therapies to reduce the impact of fibromyalgia and pain: A systematic review and meta-analysis

Background and purposePhysical exercise is one of the most effective interventions to reduce fibromyalgia symptoms. Previous studies have reported benefits of dance-based intervention on the fibromyalgia impact, health-related quality of life and pain, regardless the interventions were based on creative- or repetitive dance. This study aimed to compare the effectiveness of creative and repetitive dance interventions.MethodsPRISMA guidelines were followed in this systematic review. The Cochrane Library, PubMed, Trip, Google Scholar, Web of Science (WOS), Embase and Scopus databases were selected to identify potential articles. Studies were included if they met the following inclusion criteria: to be a clinical trial or a randomized controlled trial, include people with fibromyalgia, have a comparison group and evaluate the impact of the disease, pain or quality of life. Fifteen articles fulfilled the inclusion criteria. The methodological quality of the studies was assessed using the Cochrane Collaboration's tool.ResultsDance-based interventions significantly reduced fibromyalgia impact (standardized mean difference = −0.69), pain (standardized mean difference = −0.70 and increased quality of life (standardized mean difference = 0.43) of people with fibromyalgia. The effectiveness of dance interventions is increased when a creative component is added, since it can lead to higher improvements in pain, impact of the disease and improving quality of life.ConclusionDance-based interventions are significantly effective in reducing the impact of fibromyalgia, pain as well as increasing health-related quality of life. Subgroup analyses suggest that creative dance-based interventions could be more effective than repetitive dance-based interventions to reduce pain and fibromyalgia impact. However, results must be taken with caution due to the large heterogeneity and the small number of articles.     

Pravastatin improves fetal survival in mice with a partial deficiency of heme oxygenase-1

IntroductionStatins induce heme oxygenase-1 (HO-1) expression in vitro and in vivo. Low HO-1 expression is associated with pregnancy complications, e.g. preeclampsia and recurrent miscarriages. Here, we investigated the effects of pravastatin on HO-1 expression, placental development, and fetal survival in mice with a partial HO-1 deficiency.MethodsAt E14.5, untreated pregnant wild-type (WT, n=13–18), untreated HO-1^+/− (Het, n=6–9), and Het mice treated with pravastatin (Het+Pravastatin, n=12–14) were sacrificed. Numbers of viable fetuses/resorbed concepti were recorded. Maternal livers and placentas were harvested for HO activity. Hematoxylin and eosin (H&E) and CD31 immunohistochemical staining were performed on whole placentas.ResultsCompared with WT, HO activity in Het livers (65±18%, P<0.001) and placentas (74±7%, P<0.001) were significantly decreased. Number of viable fetuses per dam was significantly lower in Untreated Het dams (6.0±2.2) compared with WT (9.1±1.4, P<0.01), accompanied by a higher relative risk (RR) for concepti resorption (17.1, 95% CI 4.0–73.2). In Hets treated with pravastatin, maternal liver and placental HO activity increased, approaching levels of WT controls (to 83±7% and 87±14%, respectively). The number of viable fetuses per dam increased to 7.7±2.5 with a decreased RR for concepti resorption (2.7, 95% CI 1.2–5.9). In some surviving Untreated Het placentas, there were focal losses of cellular architecture and changes suggestive of reduced blood flow in the labyrinth. These findings were absent in Het+Pravastatin placentas.DiscussionPravastatin induces maternal liver and placental HO activity, may affect placental function and improve fetal survival in the context of a partial deficiency of HO-1.     

The influence of early virtual reality intervention on pain,anxiety, and function following primary total knee arthroplasty

BackgroundTotal knee arthroplasty (TKA) is one of the most popular surgeries in the orthopedic field. One of the reasons for a failed TKA is pain and difficulty to return to normal function. A pain control method that is becoming more and more popular is the use of virtual reality (VR). We aimed to examine VR intervention in the immediate post-operative physiotherapy following TKA.MethodsThis prospective randomized-controlled study recruited a total of 55 patients undergoing primary TKA in a single institute, operated by three surgeons. They were assigned either study group or control group. Both groups were treated with conventional physiotherapy and CPM equipment (Continuous passive motion device), the study group received additional VR modality. Both groups completed a series of questionnaires prior and after the intervention: State-Trait Anxiety Inventory (STAI) questionnaire (used to diagnose anxiety), Visual analog scale (VAS) for pain and the Western Ontario and McMaster Universities Arthritis Index (WOMAC) (knee function score).ResultsThe average age was 70 years-old with equal distribution of male and female. Both groups showed a decrease in pain and anxiety following the intervention (p value < 0.05) but there was no difference between the groups (p value > 0.05 for all parameters). The was no difference in the WOMAC scores in the six-month post-operative examination between groups (p-value = 0.653).ConclusionsVirtual reality intervention in the immediate post-operative period following total knee arthroplasty decrease pain and anxiety but did not influence the pain, anxiety, and long-term function results more than conventional physiotherapy.     

Long-term outcome of fetus with ameliorated cystic hygroma

ObjectiveCystic hygroma often ameliorates or disappears with pregnancy progression. Fetuses/neonates with amelioration, when without chromosomal or major structural abnormality, generally show a favorable outcome at birth. The present study was aimed to clarify the short/long-term outcomes of fetuses/neonates with the amelioration of cystic hygroma during pregnancy.Material and methodsThis was a retrospective observational study. We focused on fetuses with cystic hygroma managed in our institute between January 2006 and June 2019. The infants were followed by pediatricians (neonatologist, pediatric cardiologist, and pediatric neurologist) and pediatric outcomes were retrieved from the medical records up to 3 years old.ResultsOne hundred and seven fetuses with cystic hygroma were included. Of the 107, cystic hygromas ameliorated in 31 fetuses (31/107: 29%). Of the 31, there were 26 livebirths. Half (n = 13) of the 26 fetuses had a good outcome, whereas the remaining half (n = 13) had abnormalities. Various abnormalities were detected in their infancies. A nuchal thickness (diameter of hygroma) of ≥5 mm was significantly correlated with abnormalities (P = 0.047).ConclusionPhysicians should pay attention to fetuses/neonates with ameliorated cystic hygroma. Of those, special attention should be paid to fetuses/neonates with a nuchal thickness at diagnosis ≥5 mm.     

Intravaginal electrical stimulation as a monotherapy for female stress urinary incontinence: A systematic review and meta-analysis

Background and purposeSince patients, physiotherapists and gynaecologists continue to seek effective conservative treatments for stress urinary incontinence (SUI), the aim of this systematic review and meta-analysis was to determine the therapeutic efficacy of intravaginal electrical stimulation (ES) in women with SUI.MethodsWe searched PubMed, Embase, EBSCOHost and Ovid for randomized controlled trials. For dichotomous data, we calculated the risk ratio (RR) and 95% confidence interval (CI). For continuous data, we calculated the mean difference (MD) and 95% CI. Heterogeneity was assessed with I² statistics.ResultsOf the 686 records identified, a total of 10 articles met the inclusion criteria. A meta-analysis revealed significant differences between the ES and no active treatment groups in the pooled objective cure rates (RR: 4.20; 95% CI: 1.70 to 10.40; p = 0.001; I² = 0%) and subjective cure or improvement rates (RR: 4.96; 95%: 1.01 to 24.37; p = 0.04; I² = 0%). No significant differences were found in the pooled number of incontinence episodes per 24 h (MD: 0.16; 95% CI: 0.68 to 0.37; p = 0.56; I² = 0%), the pooled Incontinence Quality of Life Questionnaire scores (MD: 1.84; 95% CI: 2.11 to 5.80; p = 0.36; I² = 0%) or the pooled number of adverse effects (RR: 0.69; 95% CI: 0.38 to 1.27; p = 0.23; I² = 0%) between the ES and other conservative treatment groups.ConclusionThere was insufficient evidence for or against the use of intravaginal ES therapy for women with SUI, partly due to the variability in the interventions of the included trials and the small number of trials included.     

First trimester genetic sonogram for screening fetal Down syndrome: A population-based study

ObjectiveTo evaluate the performance of first trimester sonomarkers in the detection of fetal Down syndrome among Thai pregnant women.Materials and methodsPregnant women at 11–13⁺⁶ weeks’ gestation underwent ultrasound examination for assessment of nuchal translucency (NT), nasal bone (NB), tricuspid regurgitation (TR), and abnormal ductus venosus (aDV) Doppler waveforms. The women were followed up for final outcomes. Fetal abnormalities other than trisomy 21 were excluded. The performances of each sonomarker and their combinations in predicting fetal Down syndrome were calculated.ResultsA total of 7820 pregnant women meeting the inclusion criteria were available for analysis, including 20 cases with fetal Down syndrome and 7800 unaffected cases. Of the four sonomarkers, NT, as a single sonomarker, had the highest detection rate (55.0% at a false positive rate of about 5%), whereas the remaining single sonomarkers had low detection rate (15–20%). The combination of all sonomarkers had the highest detection rate of 70% but the false positive rate was as high as 10.8%. The combination of NT and NB had a detection rate of 60% with an acceptable false positive rate of 6.9%, whereas the other combinations yielded relatively high false positive rates.ConclusionThe first trimester genetic sonogram in screening for Down syndrome among Asian women is acceptably effective and may be offered to some selected groups of the population. NT is the best sonomarker with a detection rate of 55% at 5% false positive rate and its combination with NB can improve performance with minimal increase in false positive rate.     

Dance intervention for negative symptoms in individuals with autism spectrum disorder: A systematic review and meta-analysis

BackgroundAutism spectrum disorder (ASD) is a neurodevelopment disorder, marked by deficits in social communication and social interaction as well as by a restricted, repetitive patterns of behaviors, interests and activities. There is an increasing interest in the use of dance as part of rehabilitation for individuals with ASD. However, it is not clear how dance can influence on ASD symptoms. And few studies have measured and compared the outcomes of multiple studies. This study was aimed to provide a more comprehensive perspective of the efficacy of dance practice on ASD symptoms by conducting a systematic review with meta-analysis.MethodsThe electronic databases PubMed, EBSCO, MEDLINE, Cochrane and PsycINFO were searched for relevant studies reporting on the effects of dance on ASD symptoms. Only randomized controlled trials (RCTs) and non-randomized controlled studies were included in this review. Two review authors independently performed literature search, data extraction, and study quality assessment. Effect sizes for ASD symptoms were expressed as standardized mean differences (SMD) with 95% confidence intervals.ResultsSeven eligible studies were included for meta-analysis. Dance interventions varied in frequency (1–2 sessions/week), time (40 − 90 min), duration (7 − 17 weeks) and type. As compared to control groups, dance practice showed significant alleviation of overall symptoms of ASD (−1.48 points, CI −2.55 to − 0.42 points, p = 0.006, I² = 75%) and improvement in social interaction (0.88, CI 0.46 to 1.30, p < 0.0001, I² = 0%), but no significant effect on empathy (0.09, CI − 0.25 to 0.42, p = 0.61, I² = 2%).ConclusionsDance probably alleviate the negative symptoms and social deficits of individuals with ASD. However, little difference is found in empathy. Further research and studies are needed to determine the optimal dose and if dance results in greater benefits than other types of physical activity.
