A silence full of words: sociocultural beliefs behind the sexual health of Iranian women undergoing breast cancer treatment, a qualitative study.

PURPOSE: Therapeutic interventions lead to impaired sexual health in women undergoing breast cancer treatment. There are some problem such as vaginal dryness, decreased libido, decreased sexual satisfaction, and decreased frequency of sexual intercourse among breast cancer survivors. This study was conducted to discover the sexual experiences of women undergoing breast cancer treatment. METHODS: A total of 39 semi-structured interviews were held with the women undergoing breast cancer treatment, husbands, and health care providers. Recorded interviews were transcribed and analyzed using qualitative content analysis. RESULTS: Three categories of cultural and gender taboos, adherence to subjective norms, and hidden values in sexuality were revealed. The cultural and gender taboos category consisted of subcategories of learned sexual shame, fear of judgment, sexual schemas, and gender stereotypes. The adherence to subjective norms category consisted of subcategories of sexual socialization, being labeled as a disabled woman and the priority of being alive to sexuality. The hidden values in sexuality category consist of subcategories of Task-based sexuality, Tamkin, and Sexuality prevents infidelity. CONCLUSIONS: Socio-cultural beliefs affect the sexual health of women undergoing breast cancer treatment, so paying attention to this issue can improve the quality of sexual health services.

The Effects of Oxytocin on Craving, Mental Health Parameters, and Stress Hormones in Methamphetamine-Dependent Patients Undergoing Matrix Treatment Model: A Randomized, Double-Blind Clinical Trial.

BACKGROUND: Methamphetamine (METH) dependence is an increasing public health problem with a wide range of mental and physical adverse effects. Recent studies report that oxytocin (OXT) has potential therapeutic properties in drug dependence. Hence, the present study was designed to evaluate the effects of OXT on craving, mental health (depression and anxiety), and stress hormones (ACTH and cortisol) in METH-dependent patients undergoing matrix treatment model (MTM), an intensive outpatient approach for stimulant abuse treatment. METHODS: This randomized placebo-controlled clinical trial was conducted in 42 METH-dependent patients undergoing MTM to receive either intranasal OXT 40 IU (n = 21) or normal saline as placebo (n = 21) for 4 weeks. Clinical and biochemical parameters were measured at baseline and end of trials in METH-dependent patients. RESULTS: Our findings indicated that OXT administration for 4 weeks is associated with a significant improvement in the craving and depression scores, respectively (p < 0.001 and p < 0.001), but there was no significant difference for anxiety scores compared with the placebo group. In addition, OXT administration significantly decreased cortisol (p < 0.001) and ACTH levels (p < 0.002). CONCLUSIONS: These findings suggest that OXT can be considered as a new potential therapeutic for the treatment of METH-dependent patients undergoing MTM. Further studies are required to explore the effectiveness and safety of OXT.

Comparing the effect of two educational interventions on mothers' awareness, attitude, and self-efficacy regarding sexual health care of educable intellectually disabled adolescent girls: a cluster randomized control trial.

BACKGROUND: Sexual problems of intellectually disabled adolescents are associated with their inability to understand sexuality. Given the important role of parents in forming the attitude of their adolescents towards sexuality, the present study aimed to compare the effect of two educational interventions on mothers' awareness, attitude and self-efficacy regarding sexual health care of intellectually disabled adolescent girls. MATERIALS AND METHODS: This cluster randomized control trial was conducted in six intellectually disabled adolescent education centers in Isfahan, Iran in 2018. The centers were randomly assigned to intervention groups (group training and training through booklet) and control group. Mothers of educable intellectually disabled adolescent girls (n = 81) were entered into the three groups using convenience sampling and their awareness, attitude and self-efficacy regarding sexual health care of adolescent girls were assessed using questionnaires before and after the educational intervention. Data were analyzed using descriptive and inferential statistical methods. RESULTS: The mean score of mothers' awareness, attitude and self-efficacy in each of the "group training", "training through booklet group" and "control group" was significantly different after the intervention compared to before the intervention (p < 0.05). The mean score of mothers' awareness and self-efficacy after the intervention in the "group training" was higher than the "control group" and "training through booklet group" (p < 0.001). The mean score of mothers' awareness and self-efficacy after the intervention in the "training through booklet group" was higher than in "control group" (p = 0.005, p = 0.02). Also, after the intervention, the mean score of mothers' attitude in the "group training" was higher than the "control group" and the "training through booklet group" (p < 0.001), but there was no significant statistical difference between the mean score of mothers' attitude in "control group" and "training through booklet group" (p > 0.05). CONCLUSION: Implementation of the group training intervention for mothers of intellectually disabled adolescent girls in comparison with training through booklet was associated with a greater increase in their awareness, attitude and self-efficacy regarding sexual health care of adolescent girls. Therefore, group training is suggested as a suitable way to educate mothers about sexual health care of intellectually disabled adolescent girls. Trial registration IRCT, IRCT20160224026756N5.

Gender identity development in the shadow of socialization: a grounded theory approach.

Gender identity is one of the basic forms of identity which has a key role in the mental health during adolescence. The present study was conducted to determine the process of gender identity development among Iranian female adolescents. In this grounded theory study, semi-structured interviews were conducted with 55 purposefully and theoretical selected participants including 30 female adolescents and 25 key informants who lived in urban society of Isfahan, Iran, in 2016-2018. Data were analyzed using Strauss and Corbin's mode of analysis (2008), through constant comparative method, applying levels of open, axial, and selective coding with MAXQDA software. Development of gender identity in the shadow of socialization was presented as the core category extracted from the data in this study. Female adolescents would use "sexual self-expression during puberty," "attachment to parents and peers," "tendency towards the opposite sex," and "effort for social acceptance" as the main strategies in the development of gender identity until achieving "stabilized gender identity." "Girls' communicational skills" and "parents' empowerment" were the causal conditions in this process. "Gender differences" and "sociocultural texture of the society" were the contextual conditions and the influence of "peers" and "media" was the interventional conditions in the development of gender identity in female adolescents. Improving girls' communicational skills, empowering parents for managing their interactions with their daughters, adjusting gender roles in the society, and creating appropriate content by the media could have an important role in helping female adolescents achieving stabilized gender identity.

First evidence of the presence of adenovirus type 8 in myocardium of patients with severe idiopathic dilated cardiomyopathy.

Previous studies have detected adenovirus and cytomegalovirus (CMV) in cardiac tissue of patients with myocarditis. Therefore, in this study, we investigated the frequency of these viruses, which may be involved in the development of severe dilated cardiomyopathy (DCM). Myocardial tissue from of 23 cardiac transplant candidates with acute idiopathic DCM below the age of 40 years were analyzed by amplification of adenovirus and CMV DNA and subsequent sequencing. Adenovirus was detected in four (17.4%) and CMV in one (4.3%) of the patients. All controls were negative for the presence of both viruses. Our study shows that myocardial infection with adenovirus may play an important role in the pathogenesis of severe DCM and suggests that vaccination against adenovirus might be helpful in decreasing the prevalence of severe idiopathic DCM. This is the first study in which adenovirus type 8 has been detected in the hearts of patients with DCM.

A comprehensive sexual health care program for educable intellectually disabled adolescent girls: protocol for a mixed methods study.

BACKGROUND: Protection and promotion of sexual health is of great importance for educable intellectually disabled adolescent girls; since they are prone to high risk sexual vulnerabilities and consequences, such as unwanted pregnancy, sexually transmitted infections, and acquired immune deficiency syndrome. Although the rights of intellectually disabled adolescents have been emphasized through the recent years, their sexual health care is still a challenge for parents, teachers, caregivers, and service providers. This study aims to present a comprehensive sexual health care program for educable intellectually disabled adolescent girls. METHODS: This study is carried out by an exploratory sequential mixed qualitative-quantitative methods approach including three sequential phases. The researcher represents sexual health state of educable intellectually disabled adolescent girls using a qualitative approach. In the onset of the second phase, a comprehensive sexual health care program is designed for educable intellectually disabled adolescent girls. In this regard, in addition to qualitative studies, some related papers and texts are used. The suggested program of expert panel is approved based on prioritization guidelines. Then, in the third phase and after different stages of finalization of the program, its affectability is evaluated regarding improvement of sexual health state of educable intellectually disabled adolescent girls. DISCUSSION: It is expected that from the results of the present mixed methods study, by presenting a comprehensive sexual health program for educable intellectually disabled adolescent girls, lead to improvements in the sexual health of these girls. Moreover, it wants to reduce risky sexual behaviors, sexual abuse and harassment, and their consequences in adolescent girls in order to improve sexual health state of the society. If this program works, it can become one of the leading education and care guidelines for sexual health care of intellectually disabled adolescent girls. TRIAL REGISTRATION: IRCT20160224026756N5 .

Appropriate blood component therapy can reduce postcardiac surgery acute kidney injury through packed cell transfusion reduction.

BACKGROUND: Acute kidney injury (AKI) can happen due to different factors such as anemia. Packed cell (PC) transfusion is an important cause of AKI occurrence. The aim of the study is to investigate whether appropriate blood component (BC) therapy can reduce blood transfusion and it would result in AKI decreasing. MATERIALS AND METHODS: We conducted a cohort study of 1388 patients who underwent cardiac surgery in one university hospital. A serum creatinine higher than 2 mg/dl, renal disease history, renal replacement therapy (chronic dialysis) were our exclusion criteria. RESULTS: From our 1088 samples, 701 (64.43%) patients had normal kidney function, 277 (25.45%) were in the AKI-1 group, 84 (7.72%) had an AKI-2 function, and the rest of patients were classified as end stage. A mean of more than three PC units were transfused for the second and third stage of AKI, which was significantly higher than other AKI groups (P = 0.009); this higher demand of blood product was also true about the fresh frozen plasma, platelet, and fibrinogen. However, there were no needs of fibrinogen in the patients with normal kidney function. The cardiopulmonary bypass time had an average of 142 ± 24.12, which obviously was higher than other groups (P = 0.032). Total mortality rate was 14 out of 1088 (1.28%), and expiration among the AKI stages 2 and 3 was meaningfully (P = 0.001) more than the other groups. CONCLUSION: A more occurrence of AKI reported for the patients who have taken more units of blood. However, BC indicated to be safer for compensating blood loss because of low AKI occurrence among our patients.

Acceleration rate of mitral inflow E wave: a novel transmitral doppler index for assessing diastolic function.

BACKGROUND: We performed comprehensive transmitral and pulmonary venous Doppler echocardiographic studies to devise a novel index of diastolic function. This is the first study to assess the utility of the acceleration rate (AR) of the E wave of mitral inflow as a primary diagnostic modality for assessing diastolic function. METHODS: Study group consisted of 84 patients (53 + 11 years) with left ventricle (LV) diastolic dysfunction and 34 healthy people (35 ± 9 years) as control group, who were referred for clinically indicated two-dimensional transthoracic echocardiogram (TTE) during 2012 and 2013 to Imam Hospital. Normal controls were defined as patients without clinical evidence of cardiac disease and had normal TTE. LV diastolic function was determined according to standardized protocol of American Society of Echocardiography (ASE). As our new parameter, AR of E wave of mitral inflow was also measured in all patients. It was represented by the slope of the line between onset of E wave and peak of it. Correlation between AR of E wave and LV diastolic function grade was measured using the Spearman correlation coefficient. Receiver operating characteristic (ROC) curve was used to determine the sensitivity and specificity of AR of E wave in diagnosing LV diastolic dysfunction in randomly selected two-thirds of population then its derived cutoff was evaluated in rest of the population. The institutional review board of the hospital approved the study protocol. All participants gave written informed consent. This investigation was in accordance with the Declaration of Helsinki. RESULTS: The mean value of AR was 1010 ± 420 cm/s(2) in patients whereas the mean value for the normal controls was 701 ± 210 cm/s(2). There was a strong and graded relation between AR of E wave of mitral inflow and LV diastolic function grade (Spearman P ≤0.0001, rs =0.69). ROC curve analysis revealed that AR of E wave of mitral inflow =750 cm/s(2) predicted moderate or severe LV diastolic dysfunction with 89 % sensitivity and 89 % specificity (area under curve [AUC] = 0.903, P <0.0001). Application of this cutoff on test group showed 96 % sensitivity and 77 % specificity with AUC = 0.932 and P <0.0001. CONCLUSION: AR of E wave of mitral inflow could be used for assessment of diastolic function, especially moderate or severe diastolic dysfunction. However, before its clinical application, external validation should be considered.

Paradoxical attitudes toward premarital dating and sexual encounters in Tehran, Iran: a cross-sectional study.

BACKGROUND: The purpose of this study is to assess attitudes toward premarital dating and sexual encounters in individuals aged 15-49 years in Tehran. METHODS: Utilizing the attitudes section of an original cross-sectional study (n = 755) aimed at assessing sexual health needs of adults, this paper examined personal attitudes towards premarital dating, non-sexual relationships and sexual encounters in both male and female adults aged between 15-49 years. Multi-stage cluster random sampling and a validated/reliable questionnaire were used. Descriptive, bivariate and multivariate analyses were conducted using statistical software. RESULTS: The results indicated that the majority of the participants were supportive of dating. Almost three-fourths of the males were more positively inclined towards non-sexual, yet tactile, affectionate interactions between unmarried males and females as opposed to only half of the females (70 % vs. 50.5 %). Also, males held significantly more liberal attitudes than females in their acceptance of premarital sex. On preserving virginity prior to marriage, 43 % of the males felt that it was important for a female to be a virgin, whereas only 26 % felt it was important for males to remain a virgin. Interestingly, more females (61 %) supported the importance of a female's virginity compared with the importance of males' virginity (48 %). This study showed that, being a male, of a younger age, single, and being less religious or being secular were important determinants of a liberal sexual attitude. CONCLUSION: These results might reflect a socio-cultural transition in the sexual attitudes of different age groups of participants - a phenomenon that will need empirical studies to unpack in the Iranian socio-cultural context.

The Effect of Buprenorphine on Methamphetamine Cravings.

BACKGROUND: Methamphetamine (METH) abuse and dependence present a major global problem. We investigated the efficacy of adding buprenorphine in reducing METH cravings during treatment with the Matrix program. METHODS: This was a randomized, double-blind, controlled clinical trial of 40 men between the age of 18 and 40 years who were referred to the addiction treatment center at Noor Hospital from December 2012 to September 2013. All of the selected subjects participated in the Matrix program and were randomly assigned into 2 groups and given either buprenorphine or a placebo. A 4-month intervention program with buprenorphine or a placebo was arranged for each group. Demographic variables of the 2 groups, descriptive indices from the cocaine craving questionnaire-brief (CCQ-Brief), the ratio of urine tests positive for METH, and the frequency of drug complications were regularly evaluated in both groups every 2 weeks and, if not possible, by the third or fourth week. All analyses were performed by SPSS20 using analysis of covariance, χ, and t tests. RESULTS: The average of indices from the cocaine craving questionnaire-brief score, except the 2 initial measurements, was significantly lower in the intervention group in all measurements (P < 0.05). Apart from weeks 3 and 28, the ratio of positive tests was significantly different in all measurements in both groups (P < 0.05). CONCLUSIONS: Buprenorphine augmentation, in comparison with the placebo, significantly reduced the craving to use METH during treatment with the Matrix program.

Self-esteem, general and sexual self-concepts in blind people.

BACKGROUND: People with visual disability have lower self-esteem and social skills than sighted people. This study was designed to describe self-esteem and general and sexual self-concepts in blind people. MATERIALS AND METHODS: This was a cross-sectional study, conducted in the Isfahan University of Medical Sciences in 2013-2014. In this study, 138 visually impaired people participated from Isfahan Province Welfare Organization and were interviewed for measuring of self-esteem and self-concept using Eysenck self-esteem and Rogers' self-concept questionnaires. The correlation between above two variables was measured using Statistical Package for the Social Sciences (SPSS) software by Pearson correlation test. RESULTS: Mean [± standard deviation (SD)] age of patients was 30.9 ± 8 years. The mean (±SD) of general self-concept score was 11 ± 5.83. The mean (±SD) of self-esteem score was 16.62 ± 2.85. Pearson correlation results showed a significant positive correlation between self-esteem and general self-concept (r = 0.19, P = 0.025). The mean of sexual self-concept scores in five subscales (sexual anxiety, sexual self-efficacy, sexual self-esteem, sexual fear, and sexual depression) were correspondingly 11 ± 4.41, 19.53 ± 4.53, 12.96 ± 4.19, 13.48 ± 1.76, and 5.38 ± 2.36. Self-esteem and self-concept had significant positive correlation with sexual anxiety (r = 0.49; P < 0.001) (r = -.23; P < 0.001) and sexual fear (r = 0.25; P = 0.003) (r = 0.18; P = 0.02) and negative correlation with sexual self-efficacy (r = -0.26; P = 0.002) (r = -0.28; P = 0.001) and sexual-esteem (r = -0.34; P < 0.001) (r = -0.34; P < 0.001). CONCLUSION: Self-esteem and self-concept had significant correlation with sexual anxiety and sexual fear; and negative correlation with sexual self-efficacy and sexual-esteem.

Community knowledge and practices regarding malaria and long-lasting insecticidal nets during malaria elimination programme in an endemic area in Iran.

BACKGROUND: Since malaria is one of the foremost public health problems in Iran, a malaria elimination phase has been initiated and application of long-lasting insecticidal nets (LLINs) is an important strategy for control. Success and effectiveness of this community based strategy largely dependent on proper use of LLINs. In this context, to determine the community's knowledge and practices about malaria and LLINs, a study was conducted in Rudan County, one of the important malaria endemic areas in southeast of Iran. METHODS: In this cross-sectional study, 400 households in four villages were selected by cluster randomly sampling method. Community knowledge and practices about malaria and LLINs including symptoms and transmission of malaria and washing, drying and using of bed nets were investigated using pre-tested structured questionnaires. The data were analysed using SPSS.16 software. RESULTS: In this study nearly 89% of the respondents knew at least one symptom of malaria and 86.8% considered malaria as an important disease. The majority of respondents (77.8%) believed that malaria transmits through mosquito bite and 72.5% mentioned stagnated water as a potential mosquito breeding place. About 46% of respondents mentioned the community health worker as the main source of their information about malaria. Approximately 44.8% of studied population washed the LLINs once in six months and 92% of them mentioned that they dry the bed nets in direct sunlight. While 94% of households reported they received one or more LLINs by government and 60.8% of respondents mentioned that LLINs were the main protective measure against malaria, only 18.5% of households slept under bed nets the night before the survey, this use rate is lower than the targeted coverage (80%) which is recommended by World Health Organization. CONCLUSION: Although, majority of studied population were aware of the symptoms and cause of malaria, a majority had misconceptions about LLINs. Therefore, appropriate educational intervention by trained health workers should be developed for a behaviour change and motivating people to use LLINs which would improve malaria elimination programme.

Development and validation of the multidimensional vaginal penetration disorder questionnaire (MVPDQ) for assessment of lifelong vaginismus in a sample of Iranian women.

BACKGROUND: Vaginismus is considered as one of the most common female psychosexual dysfunctions. Although the importance of using a multidisciplinary approach for assessment of vaginal penetration disorder is emphasized, the paucity of instruments for this purpose is clear. We designed a study to develop and investigate the psychometric properties of a multidimensional vaginal penetration disorder questionnaire (MVPDQ), thereby assisting specialists for clinical assessment of women with lifelong vaginismus (LLV). MATERIALS AND METHODS: MVPDQ was developed using the findings from a thematic qualitative research conducted with 20 unconsummated couples from a former study, which was followed by an extensive literature review. Then, during a cross-sectional design, a consecutive sample of 214 women, who were diagnosed as LLV based on Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV-TR criteria completed MVPDQ and additional questions regarding their demographic and sexual history. Validation measures and reliability were tested by exploratory factor analysis and Cronbach's alpha coefficient via Statistical Package for the Social Sciences (SPSS) version 16. RESULTS: After conducting exploratory factor analysis, MVPDQ emerged with 72 items and 9 dimensions: Catastrophic cognitions and tightening, helplessness, marital adjustment, hypervigilance, avoidance, penetration motivation, sexual information, genital incompatibility, and optimism. Subscales of MVPDQ showed a significant reliability that varied between 0.70 and 0.87 and results of test-retest were satisfactory. CONCLUSION: The present study shows that MVPDQ is a valid and reliable self-report questionnaire for clinical assessment of women complaining of LLV. This instrument may assist specialists to make a clinical judgment and plan appropriately for clinical management.

Psychological Experiences in Women with Polycystic Ovary Syndrome: A Qualitative Study.

Background: Polycystic Ovary Syndrome (PCOS) is the most common endocrine disorder among women of reproductive years. In addition to multiple physical problems, this syndrome has many psychological complications. Thus, the present study attempted to explore the psychological experiences of women with PCOS in Iran's sociocultural context. Materials and Methods: The study was carried out in Isfahan, Iran, using a qualitative content analysis method. The participants were selected through purposive sampling from women with PCOS, their spouses, and healthcare providers in hospitals, clinics, workplaces, universities, and physicians' offices between September 2018 and November 2019. Data collection was performed through semi-structured interviews until data saturation. Data analysis was based on conventional content analysis. The interviews were transcribed and coded. Afterward, categories and concepts were extracted by grouping similar codes. Results: A total of 13 women with PCOS, four spouses, and 13 healthcare providers participated in this study. Data analysis yielded five main categories, including the patient's psychological reactions following infertility and its probability, psychological issues following menstrual disorders, patients' fear and concerns about the probability of developing chronic diseases, psychological problems following the disease, and psychological problems resulting from body appearance. Conclusions: The results of this study showed that women with PCOS were exposed to multiple psychological problems. Therefore, preventing and controlling the psychological consequences of PCOS and its complications requires healthcare providers' support and comprehensive and long-term planning to promote the mental health of these women.

Effectiveness of online sexual education based on the extended PLISSIT model on sexual function and sexual satisfaction in women undergoing breast cancer treatment.

BACKGROUND: Despite therapeutic interventions having increased the survival rate of women with breast cancer, sexual dysfunction occurs in cancer survivors due to treatment. The aim of this study is to determine the effect of online sexual education, based on the Ex-PLISSIT model on sexual function and satisfaction, on women undergoing breast cancer treatment. MATERIALS AND METHODS: The present study was a quasi-experimental and interventional control study. It was conducted with a pretest-posttest design between April and July 2022 in Isfahan, Iran. The participants were divided into an intervention (n = 40) and a control group (n = 40). The intervention group received sexual education based on the Ex-PLISSIT model that consisted of four levels of intervention, namely, permission (P), limited information (LI), specific suggestions (SS), and intensive therapy (IT), presented in four sessions. The Female Sexual Function Index (FSFI) and Larson's Sexual Satisfaction Questionnaire were used to measure the sexual function and sexual satisfaction of the participants. Data were analyzed using the Statistical Package for the Social Sciences (SPSS) version 21. P values below 0.05 were considered statistically significant. RESULTS: The results showed that the mean of sexual satisfaction and function scores in the intervention group significantly increased after intervention. Moreover, the results showed a statistically significant difference in the mean of sexual satisfaction scores between the intervention and control groups after intervention (P = 0.020). Although there was a difference between the mean of sexual function scores in the intervention and control groups after the intervention, the t-test showed no statistically significant difference (P = 0.176). CONCLUSIONS: According to the results of the study, sexual education based on the Ex-PLISSIT model could effectively enhance sexual satisfaction of women undergoing breast cancer treatment. It seems that this model can help health care providers evaluate the sexual needs of the patients and provide appropriate suggestions in order to decrease sexual problems.

Successful Pregnancy after a Heart Transplant in Iran: A Case Report.

Pregnancy after a heart transplant is a concern for many female recipients, and it remains a medical challenge that raises many questions. A 24-year-old woman, gravida 3, para 0, contacted us for obstetric care in the first trimester of gestation, about 3 years after an orthotopic cardiac transplant. She was a known case of dextrocardia with congenitally corrected transposition of the great arteries. The transplant had been performed for severe retractable heart failure, manifesting during her previous lost pregnancy. The course of the current gestation was uneventful. The patient's cardiovascular function was good throughout the pregnancy. She was admitted to the hospital for dyspnea at 35 weeks and 4 days of gestational age. A cardiovascular consult and echocardiography were performed. The results were within the normal range, and labor pains explained the patient's dyspnea. Because of labor pain, a repeat Cesarean section was performed at 35 weeks and 4 days of gestational age. A male baby weighing 2700 g, with an Apgar score of 7/9, was delivered. The patient was discharged after delivery with enoxaparin (40 mg), prednisolone (5 mg), levothyroxine, and mycophenolate mofetil (500 mg) without any complications. Follow-up was carried out at 1 month, and no abnormality was found. Here, we report a case of a successful pregnancy in a young woman after a heart transplant.

Sonification as a reliable alternative to conventional visual surgical navigation.

Despite the undeniable advantages of image-guided surgical assistance systems in terms of accuracy, such systems have not yet fully met surgeons' needs or expectations regarding usability, time efficiency, and their integration into the surgical workflow. On the other hand, perceptual studies have shown that presenting independent but causally correlated information via multimodal feedback involving different sensory modalities can improve task performance. This article investigates an alternative method for computer-assisted surgical navigation, introduces a novel four-DOF sonification methodology for navigated pedicle screw placement, and discusses advanced solutions based on multisensory feedback. The proposed method comprises a novel four-DOF sonification solution for alignment tasks in four degrees of freedom based on frequency modulation synthesis. We compared the resulting accuracy and execution time of the proposed sonification method with visual navigation, which is currently considered the state of the art. We conducted a phantom study in which 17 surgeons executed the pedicle screw placement task in the lumbar spine, guided by either the proposed sonification-based or the traditional visual navigation method. The results demonstrated that the proposed method is as accurate as the state of the art while decreasing the surgeon's need to focus on visual navigation displays instead of the natural focus on surgical tools and targeted anatomy during task execution.

Cardiovascular surgical experiences of IVC tumor and thrombus: Operative strategies Based on 51 consecutive patients.

BACKGROUND: The only beneficial treatment option for the management of inferior vena cava (IVC) tumor thrombus is complete tumor removal. The aim of this study was to report our experience in surgical and clinical outcomes in patients with tumor thrombosis in IVC. METHODS: A retrospective chart review of patients who underwent surgical resection of IVC tumor at our institution over the past 10 years was performed. The patients were identified using a prospectively maintained database. RESULTS: We identified 51 patients, the mean age was 53.4 ± 16.8 years, and 25.4% were female. They were divided into three groups based on tumor thrombosis level. Twenty patients (39.2%) required sternotomy, and cardiopulmonary bypass (CPB) was used in 19 (37.2%) patients, and 2 (3.9%) cases underwent coronary artery bypass graft. The perioperative complications were severe bleeding (3 patients), pulmonary embolism (2 patients), and duodenal perforation (1 patient). Three (5.8%) in-hospital deaths occurred, and all were due to severe abdominal bleeding. After a mean follow-up time of 46.5 ± 42.0 months, 29 (56.9%) patients were alive. The mean survival time was 75.2 ± 8.4 months. In multivariate analysis, higher age (p = 0.033) and male gender (p = 0.033) proved to be independent prognostic factors. CONCLUSIONS: Tumor thrombus extending to the IVC is a rare and challenging event. Although using CPB may be safe and result in long-term survival with acceptable function, excessive bleeding during surgery may limit the use of this method.

Comparison of spontaneous intracerebral hemorrhage treatment in Germany between 1999 and 2009: results of a survey.

BACKGROUND AND PURPOSE: The aim of our study was to examine surgical practice in the therapy of spontaneous intracerebral hemorrhage in Germany over a period of 10 years. METHODS: In 1999 and 2009 a questionnaire with 10 different cases of spontaneous intracerebral hemorrhage was sent to all neurosurgical centers in Germany. It included a cranial CT as well as a case description. The question asked if a conservative or surgical procedure was most suitable. When choosing surgery, the participants could decide between large open approach or microsurgery as well as stereotactic aspiration or external ventricular drainage. RESULTS: In 1999, 85 of 121 (70%) and in 2009 111 of 125 (89%) questionnaires could be evaluated. The results of the questionnaires from 1999 and 2009 showed no difference in the decision for or against a surgical procedure, except for a move toward conservative treatment in 1 patient with a massive spontaneous intracerebral hemorrhage. In 2 cases of isolated basal ganglia bleeding, a conservative approach was chosen by approximately 98% of the participants both in 1999 and in 2009. In all other cases of spontaneous intracerebral hemorrhage, in particular when the patient was in poor clinical condition, the decision was very heterogeneous. CONCLUSIONS: Despite new studies, there were no significant differences regarding the decision for or against a surgical procedure in 1999 and 2009. Although clearly unfavorable prognostic factors are known, many patients still undergo a surgical procedure. It appears that at least spontaneous intracerebral hemorrhage in the area of the basal ganglia is a unique domain of conservative treatment.

Effect of using 5A's model for lifestyle counseling on psychological symptoms in women with polycystic ovary syndrome: a randomized field trial.

Lifestyle modification in women with polycystic ovary syndrome (PCOS) could be associated with increased psychological symptoms. This study aimed to evaluate the effect of lifestyle modification counseling using 5A's model on the psychological symptoms of women with PCOS. This double-blind, randomized field trial was performed on 70 women with PCOS in two groups of lifestyle modification counseling based on 5A's model and counseling without using the model. The intervention was performed based on five stages of the 5A's model (Assess, Advise, Agree, Assist, Arrange) during a week, and psychological symptoms were assessed using Symptom Checklist-90-R before the intervention and one and three months after the intervention. The results showed that one and three months after the intervention, the level of psychological symptoms, except obsessive-compulsive level, were significantly lower in the intervention group than in the control group (p < 0.05). Moreover, the level of these symptoms decreased over time in the intervention group (p < 0.0001). Using the 5A's model in lifestyle modification counseling is associated with the promotion of psychological health in women with PCOS, and this model is recommended for lifestyle counseling in women with polycystic ovary syndrome.
