Background The importance of temperament in the selection of an individualized homeopathic medicine has not been evaluated systematically. The current study explored this under-researched area. Materials and Methods A prospective, open, randomized (1:1), two parallel arms, pilot trial was performed on patients suffering from various chronic diseases. Each patient's temperament was assessed using a newly developed “temperament diagnostic questionnaire”. Outcome measures were health status using the EQ-5D-5L questionnaire and a visual analog scale (VAS) of patient's self-rated health, measured at baseline and at 3 months. Homeopathic medicines were prescribed on the basis of individualization, randomly with or without accounting for individual temperament, and patients grouped accordingly (temperament(+) and temperament(−)). Baseline comparability of the two groups was checked, followed by analysis of group differences. A p-value < 0.01 was considered as statistically significant. Results Fifty protocol-compliant patients were analyzed. The two groups were comparable at baseline. Over 3 months of intervention, there was significant improvement (p < 0.01) in each group. Though improvement in the EQ-5D-5L score was greater in the temperament(+) group (mean difference, 2.4; 95% confidence interval [CI], 0.2 to 4.5), the change did not achieve the threshold for statistical significance (p = 0.029). Improvement in VAS score was significantly greater in the temperament(+) group than in temperament(–) patients (mean difference, 15.2; 95% CI, 4.9 to 25.4; p = 0.004). Conclusion Considering temperament as a key element of individualized prescription may enhance health improvement from homeopathic treatment in chronic diseases. Independently replicated rigorous trials with validated scales are warranted. Trial Registration CTRI/2018/03/012433.

Background: The American Orthopaedic Foot & Ankle Society (AOFAS) score is one of the most common and adapted outcome scales in hallux valgus surgery. However, AOFAS is predominantly physician based and not patient based. Although it may be straightforward to derive statistical significance, it may not equate to the true subjective benefit of the patient’s experience. There is a paucity of literature defining MCID for AOFAS in hallux valgus surgery although it could have a great impact on the accuracy of analyzing surgical outcomes. Hence, the primary aim of this study was to define the Minimal Clinically Important Difference (MCID) for the AOFAS score in these patients, and the secondary aim was to correlate patients’ demographics to the MCID. Methods: We conducted a retrospective cross-sectional study. A total of 446 patients were reviewed preoperatively and followed up for 2 years. An anchor question was asked 2 years postoperation: “How would you rate the overall results of your treatment for your foot and ankle condition?” (excellent, very good, good, fair, poor, terrible). The MCID was derived using 4 methods, 3 from an anchor-based approach and 1 from a distribution-based approach. Anchor-based approaches were (1) mean difference in 2-year AOFAS scores of patients who answered “good” versus “fair” based on the anchor question; (2) mean change of AOFAS score preoperatively and at 2-year follow-up in patients who answered good; (3) receiver operating characteristic (ROC) curves method, where the area under the curve (AUC) represented the likelihood that the scoring system would accurately discriminate these 2 groups of patients. The distribution-based approach used to calculate MCID was the effect size method. There were 405 (90.8%) females and 41 (9.2%) males. Mean age was 51.2 (standard deviation [SD] = 13) years, mean preoperative BMI was 24.2 (SD = 4.1). Results: Mean preoperative AOFAS score was 55.6 (SD = 16.8), with significant improvement to 85.7 (SD = 14.4) in 2 years ( P value < .001). There were no statistical differences between demographics or preoperative AOFAS scores of patients with good versus fair satisfaction levels. At 2 years, patients who had good satisfaction had higher AOFAS scores than fair satisfaction (83.9 vs 78.1, P < .001) and higher mean change (30.2 vs 22.3, P = .015). Mean change in AOFAS score in patients with good satisfaction was 30.2 (SD = 19.8). Mean difference in good versus fair satisfaction was 7.9. Using ROC analysis, the cut-off point is 29.0, with an area under the curve (AUC) of 0.62. Effect size method derived an MCID of 8.4 with a moderate effect size of 0.5. Multiple linear regression demonstrated increasing age (β = −0.129, CI = −0.245, –0.013, P = .030) and higher preoperative AOFAS score (β = −0.874, CI = −0.644, –0.081, P < .001) to significantly decrease the amount of change in the AOFAS score. Conclusion: The MCID of AOFAS score in hallux valgus surgery was 7.9 to 30.2. The MCID can ensure clinical improvement from a patient’s perspective and also aid in interpreting results from clinical trials and other studies. Level of Evidence: Level III, retrospective comparative series.

Abstract The co-occurrence analysis of Medical Subject Heading (MeSH) terms in the bibliographic database is popularly used in bibliometrics. Practically for making the result interpretable, it is necessary to apply a certain filter procedure of co-occurrence matrix for removing the low-frequency items that should not appear in the final result due to their low representativeness for co-occurrence analysis. Unfortunately, there is rare research referring to determine a critical threshold to remove noise of data for co-occurrence analysis. Here, we propose a probabilistic model for co-occurrence analysis that can calculate statistical significance (p-values) of co-occurred items. With help of this model, the dimensionality of co-occurrence network could be conveniently reduced according to selection of different levels of p-value thresholds. The conceptual model framework, simulation and practical applications are illustrated in the manuscript.

Neck contouring is one of the most frequent reasons patients seek cervicofacial rhytidectomy. But what makes for aesthetically pleasing youthful neck? Ellenbogen and Karlin described 5 criteria in their 1980 landmark publication, including having a cervicomental angle between 105° and 120° and a visible subhyoid depression. Recent advances in neck anatomy have revealed the existence of ligamentous like structures attaching the skin and platysma to the hyoid. These have been termed the hyoplatysmal ligament (HPL) and cervicomental suspensory angle ligament by different authors. This study was undertaken to determine whether surgically reestablishing the above structures utilizing a hyoid suspension technique resulted in statistically significant changes in cervicomental contour. A retrospective chart review was performed from January 2014 to present. After December 2016, the second author began utilizing a hyoid suspension technique where the inter- and subplatysmal fat was resected and the HPL was reestablished surgically (hyoid suspension). Cases before this date served as controls if a similar neck manipulation was performed without reestablishing the HPL. In total, 104 charts were queried, of which, 21 charts fit inclusion criteria to serve as controls and 20 as the experimental group. Before and after profile pictures were then compared for differences in cervicomental angle utilizing commercially available imaging software (Canfield Mirror, Parsippany, New Jersey). An unpaired Student t test was then performed to determine whether this 2 groups differed significantly utilizing a P value of .05 to denote statistical significance. The mean difference between pre- and postoperative cervicomental angle for the control group was 17.38° with a standard deviation of 8.05°. The mean difference between pre and postoperative cervicomental angle for the experimental group was 28.75° with a standard deviation of 15.52°. The resulting 11.37° difference in cervicomental angle between the 2 groups was found to be statistically significant with a P value of .0051. Our cosmetic surgical and anatomical knowledge continues to progress. Brant first described a ligamentous structure that attaches the platysma to the hyoid. Through biomechanical testing, he noted this ligament to be one of the weakest in the face and neck. Thereafter, in 2016 Yousif et al and Le Lourn separately described similar procedures to attach the platysma to the hyoid, in effect reestablishing this ligament. Utilizing one simple surgical maneuver, the hyoid suspension reestablishes the HPL. This surgically creates an acute cervicomental angle, resulting in less platysmal displacement postoperatively, with virtually no addition to surgical time or morbidity.

Purpose: Quality Function Deployment, (QFD) is a methodology which helps to satisfy customer requirements through the selection of appropriate Technical Attributes (TAs). The rationale of this article is to provide a method lending statistical support to the selection of TAs.  The purpose is to determine the statistical significance of TAs through the derivation of associated significance (P) values.   Design/Methodology/Approach: We demonstrate our methodology with reference to an original QFD case study aimed at improving the educational system in high schools in Pakistan; and then with five further published case studies obtained from literature. Mean weights of TAs are determined. Considering each TA mean weight to be a Test Statistic, a weighted matrix is generated from the VOCs’ importance ratings, and ratings in the relationship matrix. Finally using R, P-values for the means of original TAs are determined from the hypothetical population of means of TAs.  Findings: Each TA’s P-value evaluates its significance/insignificance in terms of distance from the grand mean. P-values indirectly set the prioritization of TAs. Implications/Originality/Value: The novel aspect of this study is extension of mean weights of TAs, to also provide P-values for TAs. TAs with significant importance can be resolved on priority basis, while other can be fixed with appropriateness.

Background: Psoriasis is an autoimmune chronic inflammatory disorder affecting the skin mediated by T-lymphocytes resulting in production of cytokines which cause hyperproliferation of keratinocytes.  Several factors and hormones like Prolactin have an action similar to these cytokines in promoting the multiplication of keratinocytes and other cells like lymphocytes and epithelial cells may have a role on the etiopathogenesis of psoriasis. Aim:-The aim of study is to compare the serum Prolactin levels in patients of psoriasis with a control group. Setting and study design: This is a case-control study conducted in the department of Dermatology, Venereology and Leprosy GMC, Kota over a period of 1year from July 2017 to June 2018 Material and method: The study included 100 cases of psoriasis (60 males and 40 females) and 100 controls similar for age and sex. Serum Prolactin levels were measured by ECLIA and results were obtained. Statistical analysis: Mean and standard deviation were calculated for each variable. Statistical significance of the results was analyzed using correlation analysis (Pearson correlation coefficient) and independent samples t-test. Statistical significance was assumed at p value<0.05. Result: Serum Prolactin level was significantly higher in cases of psoriasis compared to controls (p-value <0.001). PASI score and serum Prolactin levels were found to have a positive correlation (r value = 0.337; p-value: 0.001). No significant  correlation was found between serum levels of Prolactin and duration of disease r value= -0.034, P value =0.733). Serum Prolactin level was higher in male patients compared to females patients. Conclusion:- High serum Prolactin may be a biological marker of disease severity in psoriasis and may have a role in the pathogenesis of psoriasis. Further studies with large sample size are required to confirm this hypothesis.

BACKGROUND Radiology now plays a major role to diagnose, monitoring, and management of several diseases; numerous diagnostic and interventional radiology procedures involve exposure to ionizing radiation. Radiology now plays a major role to diagnose, monitoring, and management of several diseases; numerous diagnostic and interventional radiology procedures involve exposure to ionizing radiation. OBJECTIVE This study aimed to discover and compare the awareness level of radiation doses, protection issues, and risks among radiology staff in Jeddah hospitals. METHODS A cross-sectional survey containing 25 questions on personal information and various aspects of radiation exposure doses and risks was designed using an online survey tool and the link was emailed to all radiology staff in eight tertiary hospitals in Jeddah. The authors were excluded from the study. A P-value of < .05 was used to identify statistical significance. All analyses were performed using SPSS, version 21. RESULTS Out of 156 participants the majority 151 (96.8%) had poor knowledge score, where the mean scores were 2.4±1.3 for doses knowledge, 2.1±1.1for cancer risks knowledge, 2.3±0.6 for general information, and 6.7±1.9 for the total score. Only 34.6% of the participants were aware of the dosage of a single-view chest x-ray, and 9.0% chose the right answer for the approximate effective dose received by a patient in a two-view. 42.9% were able to know the correct dose of CT abdomen single phase. There is a significant underestimation of cancer risk of CT studies especially for CT abdomen where only 23.7% knew the right risk. A p-value of <0.05 was used to identify statistical significance. No significant difference of knowledge score was detected regarding gender (P =.2) or work position (P=.66). CONCLUSIONS Our survey results show considerable inadequate knowledge in all groups without exception. We recommended a conscientious effort to deliver more solid education and obtain more knowledge in these matters and providing periodic training courses to teach how to minimize the dose of radiation and to avoid risk related.

Ectopic Endometrium

Abstract Background Endometriosis is a common gynecologic disorder characterized by the implantation of the endometrial tissue ectopically outside the endometrial cavity. It affects about 10% of females at the childbearing period and is estimated to be present up to 20–50% in women complaining of infertility. While laparoscopy is considered the mainstay for diagnosis, magnetic resonance imaging (MRI) is recognized as a useful tool for definitive diagnosis, pre-surgical planning, and determining whether the patient will require multi-specialty involvement. The aim of this study is to evaluate the performance of MRI with the addition of diffusion-weighted imaging (DWI) and T2 star (T2*) to conventional MRI, for the accurate assessment of ectopic endometrium. Results Endometriotic lesions that showed diffusion restriction on DWI were 80.7%, and 96.1% of the endometriotic lesions had signal voids on the T2*W sequence, whereas only 65.4% of the lesions had typical signal intensities on T1WI and T2WI. Diagnostic performance of the MRI examination was improved by the use of the diffusion sequence and better improved by the T2* sequence, compared to the conventional MR protocol sensitivity (SE) = 96.12% and specificity (SP) = 85.7% in T2*-weighted images, SE = 80.7% and SP = 71.4% in DWI, and SE = 65.4% and SP = 71.4% in conventional MRI. P value for conventional MRI was 0.1, which is of no statistical significance (p < 0.05). P value for DWI was 0.016, which is statistically significant (p < 0.05). P value for T2*WI was 0.001, which is more statistically significant (p < 0.05) and could be adequately correlated with laparoscopy. Conclusion DWI and T2* significantly increase MRI diagnostic accuracy by allowing the detection of the hemorrhagic character of the endometriotic lesions. Studies with a large sample size are needed to confirm that they can replace invasive laparoscopy for the diagnosis of endometriosis.

Objective The study aimed to evaluate the efficacy of dual medication therapy (DMT) with oral acetaminophen and oral ibuprofen for the closure of a hemodynamically significant patent ductus arteriosus (hsPDA). Study Design In a prospective case–control cohort study (July 2017–May 2019), infants <29 weeks' gestational age and birth weight <1,000 g at ≤14 postnatal days with hsPDA and ratio of the smallest ductal diameter to the ostium of the left pulmonary artery diameter >0.5 were eligible. Infants received 10 mg/kg oral ibuprofen followed by two additional doses of 5 mg/kg at 24 and 48 hours after the initial ibuprofen dose and concomitant treatment with 15 mg/kg oral acetaminophen every 6 hours for 3 days (12 doses). Success of PDA treatment was defined as a small or absent PDA as ascertained by echocardiographic measurements. The p-values of comparisons were adjusted for multiple comparisons to preserve an error rate of 5%. Results Overall, 20 infants received oral DMT and 11 infants received intravenous single medication therapy (SMT) with ibuprofen. The rates of successful PDA treatment following the first treatment in DMT and SMT groups were not statistically different (11/20 [55%] vs. 4/11 [36%], p = 0.46). However, DMT significantly decreased PDA size (mean difference = 0.54 mm, 95% confidence interval [CI]: 0.21–0.96, adjusted p-value = 0.0002) and PDA/LPA ratio (mean difference = 0.27, 95% CI: 0.10–0.47, adjusted p-value = 0.0004). We observed no evidence of hematologic, hepatic, or renal impairment. Conclusion DMT achieved a greater degree of PDA closure than SMT and did not result in abnormalities in hepatic and renal profile. Key Points

Abstract Older adults consistently report young subjective age and provide high ratings of their subjective health. The current research examined which social comparisons older adults make when they assess their subjective age and health, as well as the effects of experimentally manipulated social comparisons on these assessments. In Study 1, 146 participants (aged 60 and over) reported to whom they compared themselves when assessing their subjective age or health. In Study 2, 100 participants (aged 60 and over) reported their subjective age and health after receiving feedback that compared them to younger adults or to their peers. Study 1 shows that participants compared themselves primarily to their peer group. Yet, individuals who selected a younger comparison group when assessing subjective age reported a younger subjective age, better self-rated health and more positive expectations regarding ageing relative to those who selected their peers as a comparison group. No equivalent differences emerged in any of the measures when participants were divided by their selection of comparison group after providing their self-rated health ratings. In Study 2, feedback that emphasised the performance of younger people led to reports of younger subjective age relative to feedback that emphasised peer performance, with no equivalent difference for self-rated health. These findings help explain why older adults feel younger and healthier than they actually are. We suggest that older adults use social comparisons as a strategy that protects them from the negative effects of ageing on self-perception.

Introduction Flow diversion is an effective treatment modality for intracranial aneurysms but is associated with ischemic and hemorrhagic complications. Patients treated with flow diversion require dual antiplatelet therapy and subsequent platelet function tests. At our institution, Thromboelastography with Platelet Mapping (TEG-PM) is the test of choice. The primary objective of this study was to identify TEG parameters that are predictive of postoperative complications in patients treated with elective flow diversion. Methods This was a retrospective study of 118 patients with unruptured intracranial aneurysms treated with flow diversion. Data was collected via chart review. Bivariate analyses were performed to identify significant variables in patients who suffered an ischemic stroke or a groin hematoma. ROC curves were constructed for the TEG parameters with statistical significance. Bivariate analyses were repeated using dichotomized TEG results. Results Patients who experienced a symptomatic ischemic stroke had a history of stroke (p value = 0.007), larger aneurysm neck width (p value = 0.017), and a higher alpha angle (p value = 0.013). Cut off point for ischemic complication is 63° on ROC curve with a sensitivity of 100% and specificity of 65%. Patients who experienced a groin hematoma were no different from their healthy peers but had a lower alpha angle (p value = 0.033). Cut off point for hemorrhagic complication is 53.3° with a sensitivity of 82% and specificity of 67%. Conclusion The Alpha Angle parameter of TEG-PM has a sizeable predictive ability for both ischemic complications of the central nervous system and hemorrhagic complications of the access site after elective flow diversion.
