Background: Intravascular leiomyomatosis (IVL) is a histologically benign smooth muscle tumor arising from the uterus that can spread through the pelvic veins and, on rare occasions, extend as far as the heart via the inferior vena cava. Despite its benign characteristics, it can behave like a malignant tumor leading to significant morbidity and even mortality if left untreated., Case Presentation: The patient is a 42-year-old woman with a past medical history of uterine leiomyomas. She presented with heavy bleeding and frequent spotting; therefore, she went to her gynecologist. After further evaluation, a mass within the uterus that expanded into the pelvic veins, inferior vena cava, and right atrium was discovered. After the complete removal of the mass, the patient underwent full recovery. IVL with cardiac extension was the final diagnosis., Conclusion: Although IVL is rare, it must be considered in women who underwent previous hysterectomies or myomectomies and present with symptoms of right heart failure. The ideal therapy will need the aid of a multidisciplinary team and will depend on the patient's symptoms, previous operative history, the tumor's extension, and resectability., (© 2023.

The potential for suboptimal psychometric performance of reverse-coded items may be particularly pronounced when scales are translated and administered in Spanish with these problems exacerbated in youth respondents. This is a significant concern, given the rapid rise in Hispanic-American and Spanish-speaking individuals in the US and their rightful, growing representation in psychological research and clinical care. The aim of this study was to examine the psychometric performance of reverse-coded items across four Spanish-speaking samples spanning developmental stages including youth, college students, and parents ( N = 1,084; Adolescents n  = 107; M  = 19.79; SD  = 2.09; 41.1% female; Caregivers n  = 58; M  = 40.79; SD  = 7.94; 60.3% female; Spanish-speaking adults in the US n  = 157; M  = 33.4; SD  = 9.5; 68.8% female; and College students living in Latin America n  = 783; M  = 21.04; SD  = 3.13; 69.2% female) and four scales (Big Five Inventory; Strengths and Difficulties Questionnaire; Difficulties in Emotion Regulation Scale; Beck Hopelessness Scale); we expected reverse-coded items would demonstrate inadequate item-total correlations and their inclusion would compromise scale internal consistency. Hypotheses were supported with evidence of poor psychometric performance for at least two reverse-coded items on each instrument, such that un-reversing the items improved their item-total correlations. Across every instrument, alpha was either improved by excluding reverse-coded items or by including them in an un-reversed fashion and, overall, there was a moderate, negative effect of reverse-coded items on scale alphas. In growing consensus with previous authors, we recommend that reverse-coded items not be included in Spanish scales., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Venta, Bailey, Walker, Mercado, Colunga-Rodriguez, Ángel-González and Dávalos-Picazo.)

Young adults and racial/ethnic minorities report the worst mental health outcomes during the COVID19 pandemic, according to the Center for Disease Control (2020). The objectives of this study were (1) to identify common mental health symptoms among Latin American, US Hispanic, and Spanish college students, and (2) to identify clinical features predictive of higher post-traumatic stress symptoms (PTSS) among this population. The study sample included 1,113 college students from the USA, Mexico, Chile, Ecuador, and Spain who completed an online survey containing demographic questions and mental health screeners. Findings revealed higher scores of depression, suicidality, and PTSS compared to pre-pandemic levels and current scores by non-Spanish speaking college students; however, less than 5% of participants endorsed clinical levels of anxiety. After controlling for demographic profiles and sociocultural values, clinical symptoms of depression, loneliness, perceived stress, anxiety, and coping strategies explained 62% of the PTSS variance. Age, history of mental illness, perceived social support, and familism were not significant predictors. This sample of college students revealed higher mental health symptoms during the COVID-19 pandemic. The high prevalence of PTSS highlights the need to develop pragmatic, cost-effective, and culturally sensitive prevention and intervention strategies to mitigate these symptoms. Implications for college administrators and clinicians are discussed., Competing Interests: Conflict of InterestThe authors declare no competing interests., (© The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2022.)

Endoscopy is essential in the assessment and treatment of the bariatric patient, especially in the postoperative state. Since bariatric surgery is increasing exponentially, endoscopists should be familiar with the anatomy and how to manage possible complications. New less invasive therapeutic tools will have a major impact on the prognosis of these patients. Dreaded complications such as leaks, stenosis or weight regain can be successfully assessed and treated by endoscopy. Postoperative evaluation of symptoms requires the precise search of details that can change patient's management.

Background: Free amino acids and acylcarnitines circulating in the blood can be used for diagnosis for metabolic illness and imbalances. To date, the normal reference ranges of amino acids and acylcarnitines in horse peripheral blood have not been established. In this study, the concentrations of 12 amino acids and 26 acylcarnitines were determined by tandem mass spectrometry in complete blood from 100 healthy horses (50 Quarter horses (QH) [23 males and 27 females] and 50 American Miniature horses (AMH) [15 males and 35 females]) with no signs of metabolic disease. The means and standard deviations were determined and data statistically analyzed., Findings: Concentrations of short, medium, and long chain acylcarnitines were significantly higher in male AMH than in male QH. The concentrations of the amino acids alanine, arginine, glycine, proline (glycogenic), and leucine (ketogenic) were higher in the QH than in the AMH. Female AMH had higher concentrations of propionylcarnitine, leucine, proline, arginine, and ornithine than female QH., Conclusions: Normal reference ranges of amino acids and acylcarnitines were established for AMH and QH. Significant differences were found in concentration of these compounds between breeds and gender.

Objective: To know factors related to job satisfaction among primary care Physicians from the Mexican Social Security Institute., Material and Methods: Cross-sectional survey applied to physicians of outpatient visit areas in four Family Medicine Units in Leon, Guanajuato, from February to May 2007. The survey explored six areas. We used 95% confidence intervals and One-Way ANOVA to compare means among clinics and Chi square and OR'95% confidence intervals to compare proportions., Results: One hundred sixty physicians participated (response rate 88.9%), three were excluded. Most physicians were satisfied with their work (86%). Half of the doctors feel satisfied with their economic benefits (48%), non-economic benefits (52%), and those from the collective bargaining agreement (53%), as well as with the labor union (46%) and their actual insurances (45%). Only one third or less of participants refer to receive incentives (31%) or recognitions for their work (33%), were satisfied with the opportunities for training (31%), the economic incentives (29%), or the salary (24%). The satisfaction's means of work, benefits, insurances, labor union and collective bargaining agreement were significantly higher than the means of salary and economic incentives. Satisfaction means were significantly higher in Clinic #53 than in Clinic #51 for job satisfaction and opportunities for training, as well as percentages of response in institutional support, incentives and recognitions for their work, were higher in Clinic 53 compared to all other clinics; however, it's the smallest clinic in this study., Conclusions: Family doctors find satisfaction in their practice, and factors such as institutional support, recognition and incentives may improve their general job satisfaction.

Objective: Paratesticular tumors are very rare and mostly bening. Wa aport a new case of adenomatoid tumor of epididymis, Method: Male of 40 years old with solid lesion in epidididymis tale treated with mass exéresis, Results: Adenoamotid tumor of the epididymis confirmed with hystopathologic technique, Conclusion: Adenomatoid tumor of epididymis is the most frequent paratesticular tumors and when is suspected, conservative surgery must be performed.

Objectives: The Nesbit technique is the reference technique for the surgical correction of the penile incurvation of Peyronie's disease. We report our experience at the Centro Urológico San Ignacio., Methods: 68 patients with stable penile incurvation who requested surgical correction. Correction of the curvature is defined as > or = 80% rectification of the pathologic angle. Mean patient age was 44 years (31-77). 53% of the patients presented difficulties for penetration, 20% partner's discomfort on intercourse, and 27% requested surgery for aesthetic reasons. Penile deviation was dorsal in 42% of the patients, to the left in 46% and to the right in 12%. The curvature angle was less than 30 degrees in 28%, between 30 degrees-45 degrees in 36%, between 45 degrees-60 degrees in 37% and > 60 degrees in 7%., Results: Mean follow-up of the series was 36 months. 20% of the patients had a penile shortening longer than 1.5 cm. 85% of the patients are satisfied with the results. The most frequent complaint was penile shortening. Correction was achieved in 92% of the patients. Four patients were reoperated: two of them for significant phimosis three months after surgery, and the other two for curvature recurrence., Conclusions: The Nesbit technique is a simple technique, with a low complication rate, and good results both in curvature correction and patient satisfaction.

Objectives: Bladder leiomyoma is a rare tumor, its frequency being estimated below 1%., Methods: We report the case of a 17-year-old mole patient presenting with hematuria and lower urinary tract irritative symptoms whose work up discovered two small bladder tumors., Results: After TUR of the lesions the diagnosis of bladder leiomyoma was established; no recurrences have appeared on follow-up., Conclusions: Bladder leiomyoma is a benign tumor, therefore surgery should be the most conservative. Bibliographic review of the Spanish urologic journals shows that this is the youngest patient reported to date.

The identification of QTL related to production traits that are relevant for the pig industry has been mostly performed by using divergent crosses. The main objective of the current study was to investigate whether these growth, fatness, and meat quality QTL, previously described in diverse experimental populations, were segregating in a Landrace commercial population selected for litter size, backfat thickness, and growth performance. We have found QTL for carcass weight (posterior P > 0.75), cutlet weight (posterior P > 0.99), weight of ham (posterior P > 0.75), shoulders weight (posterior probability > 0.99), and shear firm-ness (posterior P > 0.99) on pig Chromosome 2. Moreover, QTL with posterior P > 0.75 for fat thickness between the 3rd and 4th ribs (Chromosome 7), rib weights (Chromosome 8), backfat thickness (Chromosomes 8, 9, and 10), and b Minolta color component (Chromosome 7) were identified. These results indicate that commercial purebred populations retain a significant amount of genetic variation, even for traits that have been selected for many generations.

Objectives: Ureteroscopy with endoscopical stone fragmentation is effective in the treatment of ureteral lithiasis. We report our experience, as well as our methods., Methods: 1803 cases of ureteral stones were treated as outpatient. 44% were located in the lumbar ureter, 11% in the iliac ureter, and 45% in the pelvic ureter. Average size was 0.87 (0.4-2.2) cm. A 7 Fr Wolf rigid ureteroscope and a lithoclast type pneumatic lithotripter were employed. Lithotripsy was performed to an extent that small fragments might be spontaneously passed., Results: 98% of the stones were solved. 16% required additional ESWL. 16% of the patients required the insertion of a double J stent. 12% of the patients required more than one session. Complications appeared in 8% of the patients., Conclusions: Good results: 98% success rate. It can be performed as outpatient. The support of an ESWL unit is basic.

A 64-year-old man with dilated cardiomyopathy and chronic renal insufficiency (without dialysis) was admitted in cardiogenic shock urgently requiring a circulatory biventricular assist device (Thoratec). Twenty-nine days later we performed orthotopic cardiac and heterotopic renal transplantations with organs from the same donor. Postoperatively secondary renal insufficiency occurred due to rejection of the graft, bleeding ulcer with hypovolemic shock, and peritonitis due to Streptococcus faecalis and Candida. In the postoperative course only one rejection of the cardiac graft was detected. The patient was discharged after 4 months, resuming a normal life.

The healing process carried out during the first 72 hours of the anastomotic line of the small intestine has not been satisfactorily studied. This is a time during which intestinal transit is evaluated and oral feeding is given without being really sure whether there is resistance to rupture and if the open surgical technique favors local infection. For this study, 120 guinea pigs submitted to end-to-end anastomosis were used, 30 with continuous sutures and 30 with separate stitches, who were examined 24, 48 and 72 hours after the surgery, plus another group similarly evaluated immediately after the surgery, finding that rupture resistance is greater immediately after surgery than 48 or 72 hours later and that in these, the inflammatory process is greater and a more positive number of cultures are found. The antibiotic orally and parenterally administered did not do away with the infection but did limit further complications.

We studied 490 women aged 35 to 55 years randomly selected from the urban population of León, México. The mean age for the onset of menopause, calculated with a probit regression was 48.5 years. The median of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) increased with the rate of menopause women, but the 10th percentile for both hormones did not increase above 15 IU/L in older groups. Meanwhile, prolactin did not change. In menopause women FSH correlated positively with cigarette smoking, and negatively with body mass index. Luteinizing hormone had negative correlation with the number of pregnancies. Most symptoms studied were not associated with menopause or gonadotropins levels, except hot flushes, and the empty nest syndrome. It was concluded that during menopause, FSH increases with the smoking habit, and decreases with overweight.
