RESUMEN

Gastrointestinal (GI) symptoms such as bloating, constipation, and nausea are common in the days before menstruation, experienced by as many as 73 % of menstruating individuals. Mood may influence the link between menstrual cycle and GI symptoms, with prior studies indicating that even among healthy controls, GI symptoms worsen premenstrually and are associated with worsening mood. Associations between GI symptoms and mood are poorly understood among those with premenstrual syndrome (PMS), a cluster of mood and/or physical symptoms that occur in the week before menses affecting roughly 20 % of menstruators. Our primary aim was to examine associations between GI symptoms and mood symptoms across the menstrual cycle, in those who do and do not report PMS using a menstrual tracking app. We hypothesized that GI symptoms would be reported more frequently in the luteal phase than follicular phase, and that frequency of GI symptoms would be positively associated with mood symptoms in those with PMS. We analyzed data from 33,628 menstrual cycles across 32,241 participants, including n = 27,897 controls (29,137 menstrual cycles) and n = 4344 PMS participants (4491 menstrual cycles). GI symptoms were reported significantly more frequently in the luteal phase than the follicular phase in both control and PMS groups (p < 0.001). Mood symptoms were significantly positively associated with GI symptoms in both groups, in both follicular and luteal phases (p < 0.001). Results suggest that premenstrual GI symptoms are a common issue, and additional work is needed to explore associations between mood and GI symptoms in the context of the menstrual cycle.

RESUMEN

BACKGROUND AND AIMS: The present study evaluated the effects of two 5-HT3 serotonin receptor antagonists; granisetron and palonosetron on hemodynamics, sensory, and motor blockade induced by intrathecal bupivacaine in patients undergoing abdominal hysterectomy. MATERIAL AND METHODS: In total, 126 female patients (ASA I and II physical status) undergoing abdominal hysterectomy under spinal anesthesia with intrathecal bupivacaine were randomly divided into three groups out of which 40 patients in each group were evaluated for final outcome. Group G received intravenous 1 mg granisetron, group P received intravenous palonosetron 0.075 mg, and group C received intravenous normal saline. Study drug was given 5 min before the spinal anesthesia. Systolic, diastolic and mean arterial blood pressure, heart rate, sensory and motor blockade were assessed. RESULTS: The systolic blood pressure, diastolic blood pressure, mean arterial pressure, and heart rate showed no significant differences among the three groups. Time to reach peak sensory block and modified Bromage 3 motor block, time to two segmental regression of sensory block, and motor regression to modified Bromage score of 0 were not statistically different among the three groups. Although statistically significant early regression of sensory block to segment S1 was seen in group G as compared to group P and group C, it was of no clinical significance. The incidence of nausea and vomiting was significantly lower in group G and P. CONCLUSION: Intravenous administration of granisetron and palonosetron before intrathecal bupivacaine does not attenuate the hemodynamic changes in patients undergoing abdominal hysterectomy. Further, both 5-HT3 receptors antagonists do not have clinically significant effects on the spinal blockade produced by hyperbaric bupivacaine.

RESUMEN

BACKGROUND AND AIMS: ProSeal laryngeal mask airway (PLMA) is an established device for airway management, while Air-Q Blocker (AQB) is a relatively new supraglottic device. The aim of this study is to compare AQB against PLMA in adults undergoing laparoscopic cholecystectomy under general anesthesia. MATERIAL AND METHODS: Eighty-eight adult patients scheduled for laparoscopic cholecystectomy under general anesthesia were randomly allocated into two groups. A drain tube (gastric tube for PLMA and blocker tube for AQB) was inserted through the drain channel of the respective device. PLMA was inserted in Group P (n = 44) and AQB was inserted in Group A (n = 44) to secure the airway. The primary endpoint was airway seal pressure. Secondarily, we sought to compare overall insertion success, ease of insertion, hemodynamic effects after initial placement, ease of drain tube placement, and perioperative oropharyngolaryngeal morbidity between the devices. RESULTS: Oropharyngeal seal pressures for AQB and PLMA were 31.5 ± 2.41 and 29.41 ± 2.14 cm H2O, respectively (P = 0.01). Insertion time was longer with AQB than PLMA, 25.59 ± 5.71 and 18.66 ± 3.15 seconds, respectively (P = 0.001). Ease and success rate of insertion was better with PLMA compared to AQB. Failure of device insertion was seen in 2 cases of Group A. Gastric distension was seen in 4 patients in Group A, requiring replacement with endotracheal tube in two patients. Ventilation was successful in all 44 patients with PLMA. Both the devices were comparable in providing a patent airway and adequate oxygenation during controlled ventilation. There was an increased trend of airway trauma and complications in the AQB group. CONCLUSION: Both PLMA and AQB show similar efficacy in maintaining ventilation and oxygenation, during laparoscopic surgery. However, proper positioning and functioning of the blocker tube of AQB is a limiting factor, and needs further evaluation.

RESUMEN

Our aim was to examine the impact of TLR5 ligation in rheumatoid arthritis (RA) and experimental arthritis pathology. Studies were conducted to investigate the role of TLR5 ligation on RA and mouse myeloid cell chemotaxis or osteoclast formation, and in addition, to uncover the significance of TNF-α function in TLR5-mediated pathogenesis. Next, the in vivo mechanism of action was determined in collagen-induced arthritis (CIA) and local joint TLR5 ligation models. Last, to evaluate the importance of TLR5 function in RA, we used anti-TLR5 Ab therapy in CIA mice. We show that TLR5 agonist, flagellin, can promote monocyte infiltration and osteoclast maturation directly through myeloid TLR5 ligation and indirectly via TNF-α production from RA and mouse cells. These two identified TLR5 functions are potentiated by TNF-α, because inhibition of both pathways can more strongly impair RA synovial fluid-driven monocyte migration and osteoclast differentiation compared with each factor alone. In preclinical studies, flagellin postonset treatment in CIA and local TLR5 ligation in vivo provoke homing and osteoclastic development of myeloid cells, which are associated with the TNF-α cascade. Conversely, CIA joint inflammation and bone erosion are alleviated when TLR5 function is blocked. We found that TLR5 and TNF-α pathways are interconnected, because TNF-α is produced by TLR5 ligation in RA myeloid cells, and anti-TNF-α therapy can markedly suppress TLR5 expression in RA monocytes. Our novel findings demonstrate that a direct and an indirect mechanism are involved in TLR5-driven RA inflammation and bone destruction.

RESUMEN

Although the role of IL-7 and IL-7R has been implicated in the pathogenesis of rheumatoid arthritis (RA), the majority of the studies have focused on the effect of IL-7/IL-7R in T cell development and function. Our novel data, however, document that patients with RA and greater disease activity have higher levels of IL-7, IL-7R, and TNF-α in RA monocytes, suggesting a feedback regulation between IL-7/IL-7R and TNF-α cascades in myeloid cells that is linked to chronic disease progression. Investigations into the involved mechanism showed that IL-7 is a novel and potent chemoattractant that attracts IL-7R(+) monocytes through activation of the PI3K/AKT1 and ERK pathways at similar concentrations of IL-7 detected in RA synovial fluid. To determine whether ligation of IL-7 to IL-7R is a potential target for RA treatment and to identify their mechanism of action, collagen-induced arthritis (CIA) was therapeutically treated with anti-IL-7 Ab or IgG control. Anti-IL-7 Ab treatment significantly reduces CIA monocyte recruitment and osteoclast differentiation as well as potent joint monocyte chemoattractants and bone erosion markers, suggesting that both direct and indirect pathways might contribute to the observed effect. We also demonstrate that reduction in joint MIP-2 levels is responsible for suppressed vascularization detected in mice treated with anti-IL-7 Ab compared with the control group. To our knowledge, we show for the first time that expression of IL-7/IL-7R in myeloid cells is strongly correlated with RA disease activity and that ligation of IL-7 to IL-7R contributes to monocyte homing, differentiation of osteoclasts, and vascularization in the CIA effector phase.

RESUMEN

INTRODUCTION: Bladder stones account for 5% of all urolithiasis. Patients present with LUTS or acute urinary retention. Thus, warranting an early intervention. Minimally invasive approach with laser lithotripsy is the present gold standard to treat bladder stones. AIMS AND OBJECTIVES: To evaluate the outcomes of TFL (60 W) for bladder stones performed under local anesthesia as a day-care procedure. MATERIALS AND METHODS: This was a retrospective single-center study conducted after obtaining IRB approval. Study period was between June 2021 and June 2022 were included. All patients were operated under local anesthesia as a day care procedure. The procedure was carried out using an 18 Fr laser sheath and calculus dusted using TFL energy (15-30 W). Parameters including operative time in minutes, complications were recorded. Patients were encouraged oral and normal voiding in the immediate post-op period. RESULTS: A total of 47 patients with bladder stones presented during this period. Of these, 30 underwent laser lithotripsy (TFL) for bladder calculi. The clinical presentation of patients was LUTS in 28 (93%) and 5 (16%) patients had AUR. The average size of the stone in this series was 15 ± 2.8 mm. The mean duration of laser lithotripsy was 15 ± 5.4 min. Energy to dust the stone was variable with mean LASER energy of 18.23 ± 10 W. All patients tolerated the procedure well and none required conversion to conventional anesthesia. One patient failed to void in the post-op period. 100% clearance rate was documented in all patients. CONCLUSION: Thulium fiber laser for transurethral cystolithotripsy of bladder stones under local anesthesia is a feasible technique with minimal morbidity and good outcome.

RESUMEN

Introduction: Clinical observation skills are fundamental to the practice of medicine. Yet, the skill of looking carefully is rarely taught within the medical curriculum. This may be a contributory factor in diagnostic errors in healthcare. A growing number of medical schools, especially in the United States, have turned to the humanities to offer visual arts-based interventions to foster medical students' visual literacy. This research aims to map the literature on the relationship between art observation training and diagnostic skills of medical students, highlighting effective teaching methodologies. Methods: Based on the Arksey and O'Malley framework, a comprehensive scoping review was conducted. Publications were identified by searching nine databases and hand searching the published and grey literature. Two reviewers independently screened each publication using the pre-designed eligibility criteria. Results: Fifteen publications were included. Significant heterogeneity exists between the study designs and the methods employed to evaluate skill improvement. Nearly all studies (14/15) reported an increase in the number of observations made post-intervention, but none evaluated long-term retention rates. There was an overwhelmingly positive response to the programme, but only one study explored the clinical relevance of the observations made. Discussion: The review establishes improved observational acumen following the intervention, however, uncovers very limited evidence towards improved diagnostic abilities. There is a need for greater rigour and consistency within the experimental designs, through using control groups, randomisation, and a standardised evaluation rubric. Further research on the optimal intervention duration and the application of skills gained to clinical practice, should be performed.

RESUMEN

Acrogeria is a rare disorder that is characterized by premature aging of the distal extremities. It was first described by Gottron in 1941. Only about 50 cases have yet been reported worldwide. It is diagnosed clinically, and patients have a normal life expectancy. The disorder is seen from birth and could have an autosomal dominant or recessive inheritance. The classic features include a characteristic pinched face, thin lips, fine hair, skeletal defects, and thin, taut parchment-like skin of the extremities. We describe a case of Acrogeria, Gottron type, who also had a borderline personality disorder. However, there is very little information on the prevalence of psychopathology in patients having syndromes of premature aging.

RESUMEN

INTRODUCTION: Retrocaval ureter (RCU) is a rare congenital abnormality, secondary to anomalous development of inferior vena cava (IVC) presenting as ipsilateral obstruction needing surgical intervention. The aim of this article is to present surgical techniques and outcome of transperitoneal laparoscopic ureteropyeloplasty in patients with RCU treated by a single surgeon at a tertiary care center and with review of literature. MATERIAL AND METHODS: We conducted a retrospective, institutional review board approved chart review of patients who underwent transperitoneal laparoscopic ureteropyeloplasty for RCU at our unit between January 2010 and December 2020. A total of 10 patients were identified. Preoperative evaluation involved a computed tomography-intravenous urography in addition to the conventional evaluation. All the patients underwent dismembered transperitoneal laparoscopic ureteropyeloplasty over a Double J stent. Data analyzed included the demographic profile, operative time difficulty if any, postoperative, intraoperative complications and functional outcome. RESULTS: All cases were completed laparoscopically and no open conversion was required. Average operating time was 96.6 minutes ± 8.16. Average blood loss was 71 ± 14.49 mL with an analgesia requirement of 115 ± 33.74 mg. One patient developed postoperative urinary leak and responded to percutaneous nephrostomy drainage. Patients were followed up for 3 to 12 months with a serial ultrasound and a follow-up diethylene-triamine-penta-acetic acid renal scan at 3 months to rule out any anastomotic site obstruction. CONCLUSION: Transperitoneal laparoscopic ureteropyeloplasty for RCU was associated with minimal morbidity and good outcomes.

RESUMEN

PRCIS: In this population-based, cross-sectional study of Indian and Malay adults in Singapore aged 40 years or above, intermediate or high risk of obstructive sleep apnea (OSA) was associated with 50% higher odds of having glaucoma. BACKGROUND/AIMS: The relationship between OSA and glaucoma is unclear. We assessed the association between the risk of OSA and glaucoma in an Asian population. MATERIALS AND METHODS: In this population-based, cross-sectional study, we included Indian and Malay adults aged 40 years or above recruited between 2011 and 2015. Glaucoma was assessed by trained ophthalmologists and classified into primary open angle glaucoma (POAG) and primary angle closure glaucoma (PACG). OSA risk was assessed with the Snoring, Tiredness, Observed apnea, High blood pressure, Body mass index, Age, Neck circumference, and male Gender (STOP-Bang) questionnaire and categorized as low risk (<3) or intermediate/higher risk (≥3). We used multivariable logistic regression models to evaluate the relationship between risk of OSA and glaucoma adjusted for key variables, and further stratified for subtype and ethnicity. RESULTS: Of the 3126 participants (mean age: 63.1±9.6 y; 52.5% female), 134 (4.3%) had glaucoma, comprising 86 (2.8%) POAG, 22 (0.7%) PACG and 26 (0.8%) secondary glaucomas, and 1182 (37.8%) had an intermediate/higher risk of OSA. Compared with individuals with a low risk of OSA, individuals with intermediate/higher risk had 50% greater odds of having glaucoma (odds ratio: 1.55, 95% confidence interval: 1.03-2.33; P =0.035). We observed a nonsignificant increase in likelihood of having POAG in those with intermediate/higher risk of OSA compared with those with low risk. The OSA-glaucoma relationship was modified by ethnicity, with Malays with intermediate/higher risk of OSA having a 2-fold risk of having any glaucoma (odds ratio: 2.01, 95% confidence interval: 1.12-3.59 P =0.019); while the same elevated risk was not observed for Indians. CONCLUSIONS: Intermediate or high risk of OSA is associated with 50% higher odds of having glaucoma in our Singaporean population, with a 2-fold higher risk of glaucoma observed in Malays (but not Indians); however a conformational sleep study is needed.
