Rectal prolapse is a life-altering problem and laparoscopic ventral mesh rectopexy (LVMR) is emerging as the surgical intervention of choice. However, the literature is ambiguous on its effect on bowel function and sparse as regards bladder and sexual function. This study assesses short-term functional outcomes following LVMR.

This quantitative retrospective study with a pretest-post-test design included 130 adults who had undergone LVMR from October 2010 to December 2018 in a tertiary centre. Analysis with paired-samples
-test and Wilcoxon matched pairs test was done using SPSS (v26).

The median age was 58 years (interquartile range, 48-74 years); 123 (94.6%) were female. The median length of stay was two days (interquartile range, 1-2 days). A total of 104 (80%) sets of medical notes were reviewed. One patient had recurrence of rectal prolapse. Synthetic mesh was used in 24 patients (23.1%) and biological mesh in 80 (76.9%). One patient had extrusion of a synthetic mesh and required surgery; 31(23.8%) completed the Electronic Patient Assessment Questionnaire for Pelvic Floor. Overall, the improvement in bladder function was not statistically significant (
 = 0.670). A statistically significant improvement was seen for all bowel symptoms (
 = 0.002) excluding constipation (
 = 0.295). Irritable bowel symptoms associated with rectal prolapse improved significantly following LVMR (
 = 0.001). Vaginal prolapse (
 < 0.0005), dyspareunia (
 = 0.001) and bowel symptoms affecting sexual intercourse (
 = 0.01) improved, but improvement in overall sexual function was not statistically significant (
 = 0.081).

LVMR improves bowel function overall, although it can worsen constipation. It has the potential to improve sexual function but makes negligible difference to bladder function.

Thyroid nodules are lesions that are radiologically distinct from the thyroid parenchyma. Cervical ultrasound diagnoses 19-67% of nodules and is crucial in identifying those that lack cytological characterisation. Approximately 25% of biopsies reveal an indeterminate cytological result (Bethesda III), in which the risk of malignancy is variable (5-15%). The clinical importance of the diagnostic strategy used for thyroid nodules results from the need to exclude malignancy. The aim of this study was to evaluate the usefulness of serum thyroid-stimulating hormone (TSH) levels as a predictor of malignancy in cytologically indeterminate thyroid nodules.

Our retrospective study included 40 patients with cytologically indeterminate thyroid nodules seen in our hospital between January 2013 and December 2017. Clinical parameters were reviewed, including age, gender, serum TSH levels, family history of thyroid carcinoma, radiation exposure and some sonographic features of the nodules. Statistical analysis was performed using SPSS. Statistical significance was defined as
<0.05.

Female gender was predominant (85%) and the mean (SD) age was 53.3 (15) years. Thyroid carcinoma was confirmed in 28% of patients. Median TSH levels were higher in patients with malignant (2.73µIU/ml) compared with benign (1.56µIU/ml) nodules (
<0.05). We demonstrated an increased risk of malignancy in patients with TSH levels of 2.68µIU/ml or above (
<0.05).

Higher serum TSH levels are associated with an increased risk of thyroid carcinoma in cytologically indeterminate nodules. TSH can become a fundamental diagnostic tool in stratifying the risk of malignancy and assist in diagnostic and therapeutic approaches to these nodules.

Currently there is no single test for periprosthetic joint infection (PJI) that demonstrates an acceptable level of sensitivity. The aim of this pilot study was to identify a combination of biomarkers that could exclude periprosthetic infection prior to revision surgery in hip and knee arthroplasty. This would help in equivocal cases of PJI, such as those with low-virulence organisms, chronic low-grade infection or 'aseptic' loosening. Current research has focused on measuring the levels of biomarkers in the patient's synovial fluid, and these can be combined to improve accuracy.

We selected synovial white cell count (SF-WCC) and C-reactive protein (SF-CRP), as they demonstrated an acceptable level of sensitivity and specificity which could be measured using existing equipment. One hundred and sixty-one synovial fluid samples from 134 patients were collected and analysed prospectively using calculated cut-off values of 10mg/l for SF-CRP and 3,000×10
/l for SF-WCC. Samples were deemed positive for infection when either of the SF-CRP or SF-WCC values were above the cut-off.

The combined test demonstrated a sensitivity greater than 98.5% and specificity above 80% in all samples analysed or looked at separately for total hip replacement and total knee replacement infections. All ten aspirates taken from chronically infected joints tested positive.

The combination of SF-CRP and SF-WCC measurement has been shown to have high sensitivity of over 99% in detecting both acute and chronic PJI in both hip and knee arthroplasty. This ability of the test to exclude infection with a high degree of certainty will help in preoperative planning of PJIs.

We estimated the number of primary total hip and knee replacements (THR and TKR) that will need to be performed up to the year 2060.

We used data from The National Joint Registry for England, Wales, Northern Ireland and the Isle of Man on the volume of primary THRs (
=94,936) and TKRs (
=100,547) performed in 2018. We projected future numbers of THR and TKR using a static estimated rate from 2018 applied to population growth forecast data from the UK Office for National Statistics up to 2060.

By 2060, THR and TKR volume would increase from 2018 levels by an estimated 37.7% (
=130,766) and 36.6% (
=137,341), respectively. For both males and females demand for surgery was also higher for patients aged 70 and over, with older patients having the biggest relative increase in volume over time 70-79 years (44.6% males, 41.2% females); 80-89 years (112.4% males, 85.6% females); 90 years and older (348.0% males, 198.2% females).

By 2060 demand for hip and knee joint replacement is estimated to increase by almost 40%. Demand will be greatest in older patients (70+ years), which will have significant implications for the health service requiring forward planning given that morbidity and resource use is higher in this population. These issues, coupled with two waves of COVID-19, will impact the ability of health services to deliver timely joint replacement to many patients for a number of years, requiring urgent planning.

A major reason why mothers undergo early, unplanned breastfeeding cessation is perceived inadequate of milk supply (PIMS). We hypothesized that defining genetic polymorphisms associated with PIMS could aid early identification of at-risk mothers, providing an opportunity for targeted lactation support. Materials and Methods This prospective observational cohort study followed 221 breastfeeding mothers for 12 months, collecting medical, demographic, and breastfeeding characteristics. Eighteen mammary secretory genes were assessed for single-nucleotide polymorphisms in 88 women (45 with PIMS and 43 with perceived adequate milk supply [PAMS]), matched by age/race/parity. Hierarchical regressions were used to assess the ability of genotype to aid PIMS prediction. Results Mothers with PIMS exclusively breastfed for a shorter period (7 ± 12 weeks; p = 0.001) and reported lower mion support.

Does moderate altitude affect VO2max in acclimatized mountain guides? High Alt Med Biol 00000-000, 2021. Selleckchem PIN1 inhibitor API-1 Background Altitude exposure reduces maximal oxygen uptake (VO2max). Usually, the reduction is not restored with acclimatization (at least at altitudes above 2,500 m) and is more pronounced in highly trained athletes compared to nonathletes. It still remains to be elucidated whether these also apply for well-acclimatized individuals (i.e., mountain guides) acutely exposed to moderate altitude (i.e., 2,000 m). Methods A total of 128 acclimatized male mountain guides of the Austrian armed forces (42.2 ± 7.0 years, 177.8 ± 5.6 cm, 77.2 ± 7.0 kg) of different fitness levels performed 2 incremental cycle ergometer tests 1 week apart, one at low (600 m) and one at moderate altitude (2,000 m). Oxygen uptake, heart rate (HR), and lactate concentration were measured during the tests. Results In acclimatized mountain guides, lower baseline VO2max levels were associated with better preservation of VO2max at moderate altitude compared to higher levels.
