Objective: Patients with Richieri-Costa-Pereira syndrome (RCPS) present severe craniofacial alterations and frequently require orthodontic and surgical procedures. Thus, this study aims to describe the craniofacial relationships in patients with RCPS. Design: Panoramic radiographs and lateral cephalometric teleradiographs of 7 patients with RCPS and 7 age- and sex-matched nonsyndromic patients were analyzed. Cephalometric measurements were used to determine the size of apical bases, the relationship between them, the pattern of craniofacial growth, and the facial heights of the patients. Interobservers’ concordance was verified by intraclass coefficient. For comparison between the groups, paired t test was employed. P values <.05 indicated statistical significance. Results: Average age of patients with RCPS was 18.5 years. Six patients were female. All patients with RCPS had Pierre-Robin sequence while 2 also presented cleft mandible. Most patients with RCPS had missing lower central incisors (100%), lower lateral incisors (85.7%), lower second premolars (85.7%), and/or upper lateral incisors (57.1%). Concordance between observers was excellent for all cephalometric measurements (0.87-0.99). Patients with RCPS presented severe craniofacial alterations when compared to control group: sella–nasion–B point (SNB) angle (73.8o ± 4.86o vs 78.85o ± 4.53o, P = .029), maxillary length (7.89 cm ± 0.58 cm vs 16.36 cm ± 0.75 cm, P = .001), mandibular length (9.90 cm ± 0.46 cm vs 20.61 cm ± 0.45 cm, P = .001), upper anterior face height (5.41 cm ± 0.50 cm vs 9.40 cm ± 0.47 cm, P = .001), lower anterior face height (5.48 cm ± 0.75 cm vs 11.66 cm ± 0.55 cm, P = .001), and posterior face height (6.70 cm ± 0.33 cm vs 13.65 cm ± 1.06 cm, P = .001). There was no difference in SNB, A point–nasion–B point, pogonion–nasion–B point, and mandibular place angles between the groups ( P > .05). Conclusion: Patients with RCPS present deficient development of maxilla and mandible when compared with nonsyndromic patients.

<p><strong>OBJECTIVE:</strong> We aimed to measure abdominal pressure and placental levels of malondialdehyde in patients with preeclampsia and investigate the relationship between intraabdominal pressure and clinical features of preeclampsia.<br /><strong>STUDY DESIGN:</strong> Study was conducted at a tertiary referral clinic. Study group consisted of patients with preeclampsia and control group consisted of normotensive pregnant women. Both placental malondialdehyde and intraabdominal pressure levels were studied in all patients. Intraabdominal pressure was assessed indirectly via a Foley bladder catheter both antepartum and postpartum period. Statistical comparisons among groups were made using the Mann-Whitney U test, independent T test and Chi-square test. Statistical significance was set as p&lt;0.05.<br /><strong>RESULTS:</strong> Study and control group consisted of 35 pregnant patients. The mean patients’ age, gravidity, parity, weight and BMI were not different between study and control groups. In the study group, Caesarean, preterm delivery and abdominal hypertension rate were significantly higher whereas the mean neonatal birth weight was lower. The mean antepartum and postpartum intraabdominal pressure levels were significantly higher in study group. The mean intraabdominal pressure was highest in patients with oliguria (19.8±1.8 cmH2O). Abdominal hypertension was detected in 30 (86%) patients in study group and in 3 (9%) patients in control group. The mean placental malondialdehyde level was significantly higher in patients with intraabdominal hypertension.<br /><strong>CONCLUSION:</strong> Abdominal hypertension rate is very high in patients with preeclampsia. Abdominal hypertension may have an additional role in preeclampsia.</p>

Abstract Background: The pathogenesis of non-traumatic osteonecrosis of the femoral head (ONFH ) is related to the interruption of blood supply caused by lipid metabolism and hypercoagulability. The purpose of this study was to explore the relationship between clinical biochemical parameters and non-traumatic ONFH. Methods: The basic information and biochemical indexes of 1292 patients with non- traumatic ONFH and 1880 healthy controls were collected. SPSS software (version 22.0) was used to process and analyze the data. T-test was used for quantitative analysis. Chi-square test was used for categorical variables.p< 0.05 were the index with statistical significance. Results: In the population sample, TC (p= 0.00004), LDL (p= 0.014) and PLT (p= 0.000005) levels were statistically significant between the two groups.In men, levels of TC (p = 0.004), LDL (p= 0.011), and PLT (p= 0.00005) were statistically significant between the two groups.In women, TC (p= 0.001) and PLT (p= 0.048) levels were statistically significant between the two groups.There were differences in TC (p= 0.00001) and PLT (p= 0.031) levels between the case group and the control group in samples aged less than 45 years.There were differences in LDL (p= 0.00002) and PLT (p= 0.022) levels between the two groups in samples older than 45 years.Compared with the control group, patients with alcohol-induced ONFH had HDL (p = 0.002).LDL (p= 0.00002);The level of PLT (p= 0.0001) was significantly different.HDL (p = 0.005) was found in alcohol-induced ONFH patients younger than 45 years of age.The PLT level (p=0.045) was different from that of the control group.There was a difference in LDL (p= 0.000003) levels between control and alcohol-induced ONFH patients older than 45 years.The older the onset age, the TC in vivo;HDL;LDL;ApoA1;ApoB;The lower the PLT level.With the prolongation of the onset time, the PLT level in the patient's body is decreasing continuously.Conclusion: The changes of biochemical indexes are closely related to the occurrence of non-traumatic ONFH. Our research can provide a new direction for the prevention of ONFH.

Introduction: Endometriosis affects around 10% of women of reproductive age with symptoms of pelvic pain, dysmenorrhoea, dyspareunia, dyschezia, and infertility. Current research highlights a possible relationship between endometriosis and poor sleep quality. The aim of this study was to assess the relationship between sleep quality and endometriosis. Outcomes measured included sleep quality and quality of life and pain score. Methods: Thirty women with a histological diagnosis of endometriosis and 30 control patients completed an online questionnaire that assessed sleep quality (Pittsburgh Sleep Quality Index) and quality of life (WHO-QOL-BREF). Pain scores within the endometriosis group were evaluated using a visual analogue scale. Results: Women with endometriosis had significantly poorer sleep quality (80% vs 50%, p = 0.015) and lower quality of life scores when compared to the control group. Within the endometriosis group, there were trends between poor sleep, a reduced quality of life, and higher pain scores; however, these did not reach statistical significance. Discussion: Sleep quality and quality of life were significantly reduced in women with endometriosis when compared to controls.

The genetic heterogeneity of apolipoprotein E (apo E) has been associated with lipid profile and atherothrombotic stroke, however this association remains inconclusive. OBJECTIVE: To evaluate the relationship between the isoforms of apo E and atherothrombotic stroke, by ascertaining the frequency of its alleles and genotypes associated with the lipid profile in patients with stroke. METHOD: A total of 207 individuals were divided into two groups, consisting of 107 patients with stroke and 100 individuals without clinical symptoms of the disease. Blood samples were taken from patients and controls for molecular investigation of the apo E (epsilon2, epsilon3 and epsilon4 alleles) for the analysis of the lipid profile. RESULTS: The epsilon3 allele was the most common and its prevalence was significantly higher in patients (0.93) compared to the controls (0.86; p=0.024). The epsilon2 allele was rarely seen specifically in patients (0.02 versus 0.05 in controls, p=0.191). The epsilon4 allele was not associated with stroke showing a reduced frequency in patients (0.05) when compared to controls (0.09; p=0.011). Although higher average levels of lipid profile were found in patients when compared to controls, with statistical significance for the values of total cholesterol (TC) (203.6mg/dL±57.98 and 181.9mg/dL±68.47 respectively; p=0.003) and low-density lipoprotein cholesterol (LDLc) (131.4mg/dL±52.60 and 116mg/dL±56.38, respectively; p=0.014), these were independent of the presence of the epsilon4 allele. In control group the higher TC and LDLc values occurred in the absence of the epsilon4 allele, confirming the conflicting effect of the alleles of apo E on the plasmatic lipids and atherothrombotic stroke. CONCLUSION: The isoforms of apo E cannot be regarded as an isolated risk factor for stroke and do not show association with lipid profile in this study.

Aim: Cardiac depolarization occurs in patients experiencing pain from acute traumas, and changes in QT interval could indicate the state of ventricular depolarization. Thus, we aimed to determine the relationship between pain severity and QT interval in patients experiencing acute trauma. Material and Method: Seventy patients, who were conscutively- admitted to the Emergency Department due to moderate or severe trauma (study group), and sixty healthy individuals (control group) were included in this study. The QT interval was calculated for each group before and after analgesia and visual analog scale pain levels were recorded. Statistical analyses were performed using SPSS for Windows software (ver. 21.0; SPSS Inc., Chicago, IL, USA). Data are presented as medians±interquartile range (IQR). Statistical significance was determined using Mann-Whitney U, Wilcoxon, and chi-square tests, with a p-value <0.05 considered significant. Results: The mean age of patients with trauma and control patients was 31.50±25 years and 35.00±20 years, respectively. Among trauma patients, QT, RR and corrected QT (QTc) intervals were significantly different before and after analgesia (P<0.001). Similarly, the average pre-analgesia QT, RR and QTc values also differed between pre- and post-analgesia trauma patients (p=0.007, p<0.001, and p<0.001, respectively). However, no differences in QT values were observed before and after analgesia between patients experiencing moderate versus severe pain (p>0.05). Conclusion: In trauma patients, acute pain prolonged the QT interval, which reverted to normal following the administration of nonsteroidal anti-inflammatory drugs. However, additional comparative studies on this topic are required.

This study aimed to determine the relationship between hepcidine levels and some hematological and biochemical parameters after anemia in natural theileriosis cows. This research was conducted with a total of 25 cattle, including 10 healthy controls and 15 cattle with natural theileriosis. 1098 bp positivity was determined according to the PCR result. Leukocyte (WBC), erythrocyte (RBC), hematocrit (HCT) and hemoglobin (HGB) levels were decreased. However, red blood cell distribution width (RDW), Platelet (PLT) and hepcidin levels were increase determined in natural theileriosis cows according to the control group. In addition, a positive correlation was detected between hepsin and iron parameters although there is no statistical significance between them and a negative correlation was determined between hepcidine and HCT, HGB and RDW parameters. As a result, it was determined that erythrocyte parameters decrease and increase in iron parameters and heptidine levels in cattle with theileriosis. It can be concluded that the diagnostic importance.

Suggested Modification

The modified Rankin Scale (mRS) at 90 days after stroke onset has become the preferred outcome measure in acute stroke trials, including recent trials of interventional therapies. Reporting the range of modified Rankin Scale scores as a paired horizontal stacked bar graph (colloquially known as “Grotta bars”) has become the conventional method of visualizing modified Rankin Scale results. Grotta bars readily illustrate the levels of the ordinal modified Rankin Scale in which benefit may have occurred. However, complementing the available graphical information by including additional features to convey statistical significance may be advantageous. We propose a modification of the horizontal stacked bar graph with illustrative examples. In this suggested modification, the line joining the segments of the bar graph (e.g. modified Rankin Scale 1–2 in treatment arm to modified Rankin Scale 1–2 in control arm) is given a color and thickness based on the p-value of the result at that level (in this example, the p-value of modified Rankin Scale 0–1 vs. 2–6)—a thick green line for p-values <0.01, thin green for p-values of 0.01 to <0.05, gray for 0.05 to <0.10, thin red for 0.10 to <0.90, and thick red for p-values ≥0.90 or outcome favoring the control group. Illustrative examples from four recent trials (ESCAPE, SWIFT-PRIME, IST-3, ASTER) are shown to demonstrate the range of significant and non-significant effects that can be captured using this proposed method. By formalizing a display of outcomes which includes statistical tests of all possible dichotomizations of the Rankin scale, this approach also encourages pre-specification of such hypotheses. Prespecifying tests of all six dichotomizations of the Rankin scale provides all possible statistical information in an a priori fashion. Since the result of our proposed approach is six distinct dichotomized tests in addition to a primary test, e.g. of the ordinal Rankin shift, it may be prudent to account for multiplicity in testing by using dichotomized p-values only after adjustment, such as by the Bonferroni or Hochberg-Holm methods. Whether p-values are nominal or adjusted may be left to the discretion of the presenter as long as the presence or absence is clearly stated in the statistical methods. Our proposed modification results in a visually intuitive summary of both the size of the effect—represented by the matched bars and their connecting segments—as well as its statistical relevance.

The Relationship

<p class="abstract">Reporting statistical tests for baseline measures of clinical trials does not make sense since the statistical significance is dependent on sample size, as a large trial can find significance in the same difference that a small trial did not find to be statistically significant. We use 3 published trials using the same baseline measures to provide the relationship between trial sample size and p value. For trial 1 sequential organ failure assessment (SOFA) score, p=0.01, 10.4±3.4 vs. 9.6±3.2, difference=0.8; p=0.007 for vasopressors, 83.0% vs. 72.6%. Trial 2 has SOFA score 11±3 vs. 12±3, difference=1, p=0.42. Trial 3 has vasopressors 73% vs. 83%, p=0.21. Based on trial 2, supine group has a mean of 12 and an SD of 3 for SOFA score, while prone group has a mean of 11 and an SD of 3 for SOFA score. The p values are 0.29850, 0.09877, 0.01940, 0.00094, 0.00005, and &lt;0.00001 when n (per arm) is 20, 50, 100, 200, 300 and 400, respectively. Based on trial 3 information, the vasopressors percentages are 73.0% in the supine group vs. 83.0% in the prone group. The p values are 0.4452, 0.2274, 0.0878, 0.0158, 0.0031, and 0.0006 when n (per arm) is 20, 50, 100, 200, 300 and 400, respectively. Small trials provide larger p values than big trials for the same baseline differences. We cannot define the imbalance in baseline measures only based on these p values. There is no statistical basis for advocating the baseline difference tests</p>

Objective Investigation

Objective. Investigation of the relationship between the first trimester complete blood count parameters and miscarriage. Materials and Methods. The study group consisted of 39 patients who admitted to the hospital with the diagnosis of abortus imminens between January 2016 and December 2019, and whose pregnancy ended as miscarriage before the 20th week. The control group consisted of 200 randomly selected healthy pregnant women, with follow-up and delivery in our hospital. Patient information was obtained retrospectively from the hospital records. Results. Age and BMI of both groups were similar. There was no significant difference between the two groups in terms of basophil, neutrophil, eosinophil, lymphocyte, monocyte, platelets, RBC, hemoglobin, hematocrit, MCV, MCH, MCHC, RDW, MPV, Pct and PDW, while leukocyte and neutrophil counts was statistically significantly higher in the miscarriage group (p=0,002, p=0,001, respectively). NLR was statistically higher in the miscarriage group (p=0,005), PLR was also higher in the miscarriage group, but this did not reach statistical significance (p=0,056). Both groups were similar in terms of MLR. Conclusions. High NLR levels obtained from the hemogram results in the first trimester seems to be associated with miscarriage. NLR can be an easy, cheap and useful tool for predicting pregnancy prognosis in patients with abortus imminens.

The Relationship

The aim of this study, which was carried out in the French-speacking part of Switzerland, was to examine the relationship between suicide attempts and self-mutilation by adolescents and young adults. The population, aged 14-25 years (N = 308), included a clinical sample of dependent subjects (drug abuse and eating disorders) compared to a control sample. On the basis of the Mini Neuropsychiatric Interview ( Sheehan et al., 1998 ), DSM-IV criteria were used for the inclusion of the clinical population. The results concerning the occurrence of suicide attempts as well as on self-mutilation confirm most of the hypotheses postulated: suicidal attempts and self-mutilation were more common in the clinical group compared to the control group, and there was a correlation between suicide attempts and self-mutilation. However, there was only a partial overlap, attesting that suicide and self-harm might correspond to two different types of behaviour.
