Although indirect data suggest a relationship between lymphatic pumping and CM production, this concept requires more experimental evidence before we can be sure that lymphatic pumping contributes significantly to the rate of CM appearance in the blood circulation.

The digested products of dietary fats absorbed by the small intestine are re-esterified and packaged by enterocytes into large, triglyceride-rich CM particles or stored temporarily in intracellular cytoplasmic lipid droplets. Secreted CMs traverse the lamina propria and are transported via lymphatics and then the blood circulation to liver and extrahepatic tissues, where they are stored or metabolized as a rich energy source. Although indirect data suggest a relationship between lymphatic pumping and CM production, this concept requires more experimental evidence before we can be sure that lymphatic pumping contributes significantly to the rate of CM appearance in the blood circulation.

The aim was to investigate whether pretreatment pain characteristics, psychological variables, and pelvic floor muscle (PFM) function predict the response to physical therapy (PT) in women with provoked vestibulodynia (PVD).

One hundred-five women diagnosed with PVD underwent 10 weekly sessions of individual PT comprising education, PFM exercises with biofeedback, manual therapy, and dilators. Treatment outcomes were evaluated at pretreatment, post-treatment, and 6-month follow-up and included pain intensity (numerical rating scale 0 to 10) and sexual function (Female Sexual Function Scale). Multilevel analyses were used to examine the potential predictors of response over time including pain characteristics (PVD subtype, pain duration), psychological variables (fear of pain, pain catastrophizing), and PFM function assessed with a dynamometric speculum (tone, flexibility, and strength).

PVD subtype and PFM tone were significant predictors of greater treatment response for pain intensity reduction. Secondary PVD (ie, pain developed after a period of pain-free intercourse) and lower PFM tone at baseline were both associated with greater reduction in pain intensity after PT and at follow-up. Among the psychological variables, fear of pain was the only significant predictor of better treatment response when assessed through improvement in sexual function, where higher fear of pain at baseline was associated with greater improvement after PT.

This study identified PVD secondary subtype, lower PFM tone, and higher fear of pain as significant predictors of better treatment response to PT in women with PVD.

This study identified PVD secondary subtype, lower PFM tone, and higher fear of pain as significant predictors of better treatment response to PT in women with PVD.Our work aims to identify and measure the morpho-anatomical characteristics of too-long anterior calcaneal process based on computed tomography scans done in patients with a history of pain and who have experienced repeated ankle sprains. The computed tomography scans of 69 feet were reviewed. These scans were used to calculate (1) the calcaneo-navicular distance; (2) the height, length, and width of the too-long anterior calcaneal process; (3) the length of the calcaneum; (4) the angle of the too-long anterior calcaneal process in the sagittal (anterior-superior angle), axial (anterior-medial angle), and frontal plane. Out of 69 feet, forty-nine were pathological (71%) with abnormalities of the too-long anterior calcaneal process, while the rest (29%) had no morphological abnormalities. The calcaneo-navicular distance was found to be less then 5 mm (mean 2.8 ± 1.2 mm) in all pathological feet, which also had significantly reduced calcaneo-navicular distance (P less then 0.001) and longer bone portion distal to the calcaneocuboid tangent (P less then 0.001) in comparison to normal feet. In pathological feet, the mean too-long anterior calcaneal process length was 10.7 ± 1.9 mm; the mean anterior-superior angle was 29.6 ° ± 11.6, the mean angle anterior-medial angle was 40.7 ° ± 8.3, the mean angle frontal plane was 74.2 ° ± 14.1. Similar to a cone or a parallelepiped, the too-long anterior calcaneal process has a complex three-dimensional anatomy, with a superior, medial, and anterior direction. Using the measurements obtained, four different too-long anterior calcaneal process morphotypes could be identified absence of TLAP, triangular shape, rectangular shape, and coalition (level of evidence III).The purpose of this study was to examine whether measurement accuracy is impacted with a low radiation radiograph technique. Treatment decisions for hip dysplasia require serial radiographs to monitor acetabular anatomy. However, radiation use creates concern for future malignancy. Standard radiograph technique utilizes a grid to enhance clarity, but requires a larger X-ray dose. We hypothesized grid removal would lower radiation exposure without decreasing measurement accuracy. This is a retrospective cohort study of patients with idiopathic DDH and neuromuscular hip displacement at a single institution from 2019 to 2020 receiving surveillance radiographs. A cohort receiving modified technique radiographs (grid removed) was compared to an age-matched cohort receiving standard technique radiographs. Four examiners measured radiographs on two separate occasions, a minimum of 2 weeks apart. Migration percentage (MP) was measured for neuromuscular patients and acetabular index (AI) for idiopathic DDH. Intraclass correlation coefficient (ICC) with a 95% confidence interval (CI) was used to evaluate inter-observer and intra-observer agreement for measurements. Average radiation dose for both techniques. A total of 134 age-matched patients were included for measurement of MP. Thirty age-matched patients were included for AI measurements. Inter and intra-rater reliability of MP and AI were not different with or without use of the grid. There was a 50-75% decrease in radiation dose per radiograph following grid removal, dependent on patient size. The adjusted radiograph technique showed no significant difference in MP or AI reliability. A slight decrease in picture contrast did not jeopardize measurement reliability and decreased radiation exposure for the patient significantly. This simple technique can be useful for patients requiring multiple radiographs over time.Apophyseal avulsion fractures of the ischial tuberosity (AFIT) in pediatric athletes are relatively uncommon injuries with treatment and return to sport (RTS) outcomes being largely unknown. The purpose of this review is to perform a systematic review analyzing RTS and predictors of successful RTS for pediatric athletes sustaining AFIT. Studies reporting on athletes strictly under the age of 18 years sustaining an AFIT with reported RTS status were included. RTS was analyzed based on injury acuity, mechanism, and management, whereas the incidence of any complications was recorded. A total of 33 studies comprising 90 cases of AFIT were identified. The mean age of athletes sustaining injuries was 14.7 + 1.4 years (range, 9-17 years), most commonly participating in soccer ( n = 25), sprinting ( n = 21), and gymnastics ( n = 7). Acute trauma during sporting activities was responsible for 74.4% ( n = 77/90) of injuries. A total of 82% ( n = 74/90) of athletes reported successful RTS at an average of 7.0 + 5.0 months. Athletes undergoing surgery had a significantly higher RTS rate ( n = 36/38, 94.7%) compared with athletes treated nonoperatively (n = 38/52, 73.08%; P = 0.008). When reported, a high rate of misdiagnosis was reported (39.4%, n = 28/71). Complications were reported in 15.8% ( n = 7/38) and 32.7% ( n = 17/52) of athletes managed surgically and conservatively, respectively. As such, the high rate of misdiagnosis and subsequent high rate of complications and poor rate of RTS highlight the importance of accurate diagnosis and treatment. Future prospective studies evaluating patient outcomes based on fracture displacement, sporting activity, and management strategies are warranted to better treat pediatric athletes. Study design Level IV, systematic review.Clavicle fractures are a common injury in the pediatric and adolescent population. Calpeptin datasheet Most fractures are located in the middle third of the clavicle. There has been no information in the literature regarding the management of extra-physeal medial clavicle shaft fractures in this population. The objective of this study is to evaluate demographic and injury characteristics, management options and clinical outcomes of medial clavicle fractures in children and adolescents and differentiate them from those in adults. A retrospective review was performed at a single institution to identify patients with medial clavicle shaft fractures. Radiographs, clinical features and patient-reported outcomes (QuickDASH) were analyzed. Eight patients were identified with medial clavicle fractures. Two fractures could not be diagnosed on anteroposterior radiographs. Both operative (four patients) and nonoperative (four patients) treatment had excellent radiographic and clinical outcomes, irrespective of initial displacement. Compared to high-energy and life-threatening injuries in adults, these fractures in children and adolescents were sports-related and isolated fractures. Conservative treatment should be considered for medial clavicle fractures in children and adolescents. These fractures are distinct from their adult counterparts and do not lead to increased morbidity or mortality.Despite the importance of blood pressure (BP) variability to estimate cardiovascular risk in patients with hypertension, not all exercise modalities can reduce short-term BP variability, and no studies have measured the acute effects of recreational sports on short-term BP variability. We investigated the acute effects of a single beach tennis (BT) session on short-term BP variability in individuals with hypertension. Twenty-two participants took part in this randomized clinical trial. They were randomly allocated to a BT session and a nonexercise control session (Con). BT and Con sessions lasted 45 min. Office BP and heart rate were measured throughout the experimental sessions to calculate rate-pressure products and estimate the cardiovascular demand of BT. To determine short-term BP variability after BT and Con sessions, average real variability (ARV) of systolic BP and diastolic BP was assessed over 24 h using ambulatory BP monitoring. Compared with Con, there were lower 24-h (Δ, -0.9 ± 0.4 mmHg; P = 0.049) and daytime (Δ, -1.4 ± 0.5 mmHg; P = 0.004) ARV of diastolic BP after BT. There were no significant differences in ARV of systolic BP between Con and BT. There was a higher rate-pressure product found during BT (P less then 0.001). However, after the experimental sessions, there was no significant difference between BT and Con for the rate-pressure product under ambulatory conditions. In conclusion, a single BT session reduced daytime and 24-h diastolic BP variability in adults with hypertension. Trial registration ClinicalTrials.gov, NCT03909308.

Hypertensive disorder complicating pregnancy (HDCP) consists of various heterogeneous conditions. Long noncoding RNAs (LncRNA) FAM99A is implicated in HDCP diagnosis. This study discussed the diagnostic efficiency of lncRNA FAM99A in HDCP.

Totally 130 singleton HDCP patients including 50 patients of gestation hypertension (GH), 44 of mild preeclampsia (mPE), and 36 of severe preeclampsia (sPEz) were enrolled, with 70 healthy pregnant women as the control. Serum lncRNA FAM99A expression was detected and its diagnostic efficiency in HDCP was analyzed using the receiver operating characteristic curve. The influencing factors of PE grade were analyzed using the logistic regression model.

Serum lncRNA FAM99A was downregulated in HDCP patients. The SBP/DBP, 24-h urinary protein, and serum creatinine (SCr), AST and ALT contents were elevated, and platelet count (PLT) was diminished in HDCP patients. Relative to the high-expression group, SBP/DBP, 24-h urinary protein, SCr, AST, and ALT contents were raised, and PLT was lowered in the low-expression group.
