Stress urinary incontinence often results from pelvic support structures' weakening or damage. This dysfunction is related to direct injury of the pelvic organ's muscular, ligamentous or connective tissue structures due to aging, vaginal delivery or increase of the intra-abdominal pressure, for example, defecation or due to obesity. Mechanical changes alter the soft tissues' microstructural composition and therefore may affect their biomechanical properties. This study focuses on adapting an inverse finite element analysis to estimate the in vivo bladder's biomechanical properties of two groups of women (continent group (G1) and incontinent group (G2))...

INTRODUCTION: For the diagnosis of Eustachian tube dysfunction (ETD), clinical procedures such as tympanometry, micro-otoscopy, and maneuvers according to Toynbee and Valsalva only allow an indirect assessment for the moment. With a prevalence of up to 5%, the selection of patients with ETD and its subtypes is clinically relevant. Dynamic methods of Eustachian tube function assessment include a hypo/hyperbaric pressure chamber and Estève's tubomanometer (TMM). One method of assessing ETD is the evaluation of Eustachian tube opening pressure (ETOP)...

IMPORTANCE: Paroxysmal supraventricular tachycardia (PSVT), defined as tachyarrhythmias that originate from or conduct through the atria or atrioventricular node with abrupt onset, affects 168 to 332 per 100 000 individuals. Untreated PSVT is associated with adverse outcomes including high symptom burden and tachycardia-mediated cardiomyopathy. OBSERVATIONS: Approximately 50% of patients with PSVT are aged 45 to 64 years and 67.5% are female. Most common symptoms include palpitations (86%), chest discomfort (47%), and dyspnea (38%)...

INTRODUCTION: Pelvic organ prolapse (POP) is a significant health concern for young Nepali women, with potential risk factors including pelvic floor trauma from vaginal delivery and heavy lifting. The prevalence of symptomatic POP (SPOP) among nulliparous women in Nepal is 6%, while the general population of Nepali women aged 15-49 years reports a prevalence of 7%. Surprisingly, the average age of SPOP onset in Nepal is 27 years, challenging the assumption that postmenopausal age and vaginal delivery are the sole risk factors...

Cerebral aneurysms are rarely encountered in pregnancy. Their antepartum and intrapartum management remain clinically challenging, primarily due to concern regarding potential rupture. We present a case of a patient in preterm labor at risk for imminent delivery with a 10mm cerebral aneurysm. She was recommended for cesarean section (CS), yet delivered via spontaneous vaginal delivery in the operating room after induction of general anesthesia for the intended CS. Her aneurysm and neurologic function remained intact postpartum...

BACKGROUND: A considerable link between personality types and cardiovascular diseases (CVDs) has been seen. Autonomic responses in both type A and type B personality individuals were found to be influenced by their personality traits. The study suggests further research on cardiac autonomic functions in larger sample sizes and the use of non-invasive screening techniques like cardiovascular reflex tests to stratify participants' risk of future illness. OBJECTIVE: This study aimed to assess autonomic stress reactivity tests in type A and type B personalities using cardiovascular reflex tests...

OBJECTIVES: The efficacy of using a single electrical or magnetic stimulation for treating pelvic floor dysfunction is limited. This study aims to investigate the efficacy of radiofrequency combined with magnetic stimulation treatment for mild to moderate pelvic organ prolapse. METHODS: Patients who completed the treatment in the Third Xiangya Hospital, Central South University were screened, and were divided into 2 groups based on different treatment plans. There were 28 patients who completed magnetic stimulation therapy (the magnetic stimulation therapy group) and 21 patients who completed radiofrequency combined with magnetic stimulation therapy (the combined treatment group)...

Postoperative pain is a major clinical problem imposing a significant burden on patients and society. In a survey 2 years after orthopedic surgery, 57% of patients reported persisting postoperative pain. However, only limited progress has been made in the development of safe and effective therapies to prevent the onset and chronification of pain after orthopedic surgery. We established a tibial fracture mouse model that recapitulates clinically relevant orthopedic trauma surgery, which causes changes in neuropeptide levels in dorsal root ganglia and sustained neuroinflammation in the spinal cord...

In rats and guinea pigs, sensory innervation of the airways is derived largely from the vagus nerve, with the extrapulmonary airways innervated by Wnt1+ jugular neurons and the intrapulmonary airways and lungs by Phox2b+ nodose neurons; however, our knowledge of airway innervation in mice is limited. We used genetically targeted expression of enhanced yellow fluorescent protein-channelrhodopsin-2 (EYFP-ChR2) in Wnt1+ or Phox2b+ tissues to characterize jugular and nodose-mediated physiological responses and airway innervation in mice...

Venipuncture is a common invasive clinical procedure, and pain management during puncture has been of interest to healthcare professionals. The purpose of this systematic review and meta-analysis was to evaluate the efficacy and safety of the Valsalva maneuver (VM) for the relief of venipuncture pain in children and adults. PubMed, Embase, Web of Science, Cochrane Library, CNKI, Wanfang, VIP database, and CBM were searched from inception to December 2023 for all available randomized controlled trials (RCTs) that evaluated the impact of VM on venipuncture...

A patient with a swelling of the abdominal wall is a regular occurrence in general practice and hospital. The diagnosis can often be made with a thorough history and physical examination. An abdominal wall hernia is characterized by an increase in swelling on standing physical examination and Valsalva maneuver, which is often reducible, and a hernia defect is palpable. If no interruption of the abdominal wall is palpable and there is hypoesthesia, there may be an abdominal wall paresis because of thoracic paramedian hernia nuclei pulposi (HNP)...

BACKGROUND: Although cardiac autonomic markers are commonly used to assess cardiac reinnervation in heart transplant patients (HTx), their relationship to the degree of sympathetic and vagal cardiac reinnervation is not well understood yet. To study this relationship, we applied a mathematical model of the cardiovascular system and its autonomic control. METHODS: By simulating varying levels of sympathetic and vagal efferent sinoatrial reinnervation, we analyzed the induced changes in cardiac autonomic markers including resting heart rate (HR), bradycardic and tachycardic HR response to Valsalva Maneuver, root mean square of successive differences between normal heartbeats (RMSSD), low-frequency- (LF), high-frequency- (HF), and total spectral power...

We explored the non-invasive evaluation of the sympathetic nervous system (SNS) by employing two distinct physiological signals: skin sympathetic nerve activity (SKNA), extracted from electrocardiogram (ECG) signals, and electrodermal activity (EDA), a well-studied marker in the context of the SNS assessment. Our investigation focused on cognitive stress and pain; two conditions closely associated with the SNS. We sought to determine if the information and dynamics of EDA could be derived from the novel SKNA signal...

Introduction  Balloon eustachian tuboplasty (BET) allows the treatment of the main etiology of eustachian tube disfunction (ETD). Objective  To evaluate the efficacy of isolated BET, through objective and subjective results, in the short and medium term, in patients with chronic obstructive ETD. Methods  Adult patients diagnosed with chronic obstructive ETD who underwent BET between January 2018 and December 2020 were enrolled in the study. We performed a prospective observational study of BET efficacy, by comparing subjective data, based on the Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7), and objective data, obtained by tympanometry, objective Valsalva maneuver and tubomanometry, prior to BET with these outcome tools on postprocedure follow-up...

Vagal maneuvers are techniques used to increase parasympathetic tone, particularly useful in the management of hemodynamically stable supraventricular tachycardias. If ineffective, adenosine can be attempted. We present a patient with atrioventricular nodal re-entrant tachycardia (AVNRT), who could not effectively perform Valsalva maneuvers and had contraindications for carotid massage and adenosine administration, that converted into sinus rhythm by using a rectal thermometer. This maneuver was reproduced on various occasions...
