ABSTRACT

BACKGROUND AND PURPOSE: Vertical femoral neck fractures (VFNFs) are one of the most difficult fractures to stabilize, with high non-union (17%), avascular necrosis (AVN, 21%), and femoral neck shortening (FNS, 29.0%) rates. The objective of this investigation was to directly compare the long-term clinical complication rates of VFNFs repaired by crossed (Alpha fixation) or parallel screws in non-geriatric patients.

PATIENTS AND METHODS: We conducted a retrospective comparative study of VFNFs in patients (<60 years) between January 2014 and December 2017, with at least 2 years of follow-up. VFNFs were fixed with either three parallel screws (G-TRI) or augmented with a crossed screw (G-ALP). Confounding variables included age, gender, initial displacement, ISS (Injury Severity Score), general comorbidities, combined fractures, Pauwels angle, reduction quality. Complications, including non-union, AVN of the femoral head and FNS were compared as outcome indicators. Risk factors associated with these variables were further analysed using multivariate analysis.

RESULTS: A total of 157 patients (97 G-TRI; 60 G-ALP) met inclusion criteria. G-ALP had a significantly lower rate of FNS (8.3% vs. 28.9%, p = 0.039) than that of G-TRI. non-union (3.3% vs. 11.3%), AVN (21.7% vs. 25.8%), and reoperation rates (21.7% vs. 23.7%) were lower in G-ALP than G-TRI but was not statistically significant. Multivariate analyses showed significant relationships between NU and unacceptable reduction quality (OR=7.610; 1.823-31.770, adjusted-p = 0.015); between AVN and initial displacement (Garden III and IV) (OR=7.885; 1.739-35.744, adjusted-p = 0.021); and between FNS and screw configuration (OR=5.713; 1.839-17.743, adjusted-p = 0.009).

CONCLUSION: For the treatment of VFNFs, satisfactory reduction still remains the key surgical goal that prevents NU, while the incidence of AVN strongly depends on the initial displacement at the time of injury. Crossed screws were associated with a markedly lower FNS rate than parallel screws, which promote further randomised controlled trials to establish a guideline for optimal fixation selection in VFNFs.

ABSTRACT

Perineural anaesthesia is an essential part of lameness investigation in horses. Painful reactions to injections imply a high risk of accidents for veterinarians. To evaluate the efficacy of two topical anaesthetic creams on desensitization of the skin at two perineural injection sites and to evaluate the effects these formulations may have on pain perception distally to the application sites. Randomized, blind, prospective study. 14 healthy horses were randomly divided in two groups of 7 horses each, one treated with EMLA and one with PLIAGLIS preparations. The mechanical nociceptive threshold (MNT) was recorded via pressure algometer at the baseline and one hour after application (T1) on palmar and palmar digital nerve blocks sites. Skin sensation was also assessed on the distal limb, recording MNT on the coronary band and on both bulbs of the heels. Data were compared with a 3-way ANOVA statistical analyses. No significant difference was encountered in the MNT values between baseline records and records at T1 at the control sites. A significant difference of MNT values was detected between the two time points in the treated limbs. The significant sources of variation in our study were the time and the presence of anaesthetic cream. The type of treatment did not determine any differences. Furthermore, no significant difference of MNT values at sites distal to treatment was recorded between the two time points, both in the treated limb and control limbs. Both formulations are effective to obtain superficial skin desensitization.

ABSTRACT

Equine asthma is a common condition in horses, for which few host-related risk factors have been identified. The objective of this study was to identify host-related risk factors for the development of equine asthma. A retrospective, case-control study was performed, utilizing horses presented to the Texas A&M University, Veterinary Medical Teaching Hospital from January 2014 December 2018. Incident cases of mild to severe equine asthma (n = 37), diagnosed clinically with cytologic support of disease were examined. For each case, two control populations were identified, including one temporal control (n = 37) and one age-matched control (n = 37). Data collected included signalment, dietary and stable management, prior medical history, metabolic status, physical examination findings, and results of cytologic evaluation via bronchoalvelolar lavage or tracheal wash. Conditional logistic regression was used to compare data on equine asthma cases with data from each set of controls. Results indicated that obesity (Body Condition Score ≥ 7) was the only statistically significant risk factor for equine asthma in this population of horses. These results may aid in identification of targets for management, prevention, and further investigation into the pathogenesis of equine asthma. Early identification and intervention of horses at risk of lower airway disease could ameliorate the impact of disease.

ABSTRACT

BACKGROUND: LAMA2-related muscular dystrophy including LAMA2-related congenital muscular dystrophy (LAMA2-CMD) and autosomal recessive limb-girdle muscular dystrophy-23 (LGMDR23) is caused by LAMA2 pathogenic variants. We aimed to describe the natural history and establish genotype-phenotype correlations in a large cohort of Chinese patients with LAMA2-related muscular dystrophy.

METHODS: Clinical and genetic data of LAMA2-related muscular dystrophy patients enrolled from ten research centers between January 2003 and March 2021 were collected and analyzed.

RESULTS: One hundred and thirty patients (116 LAMA2-CMD and 14 LGMDR23) were included. LAMA2-CMD group had earlier onset than LGMDR23 group. Head control, independent sitting and ambulation were achieved in 76.3%, 92.6% and 18.4% of LAMA2-CMD patients at median ages of 6.0 months (range 2.0-36.0 months), 11.0 months (range 6.0-36.0 months), and 27.0 months (range 18.0-84.0 months), respectively. All LGMDR23 patients achieved independent ambulation at median age of 18.0 months (range 13.0-20.0 months). Motor regression in LAMA2-CMD mainly occurred concurrently with rapid progression of contractures during 6-9 years old. Twenty-four LAMA2-related muscular dystrophy patients died, mostly due to severe pneumonia. Seizures occurred in 35.7% of LGMDR23 and 9.5% of LAMA2-CMD patients. Forty-six novel and 97 known LAMA2 disease-causing variants were identified. The top three high-frequency disease-causing variants in Han Chinese patients were c.7147C > T (p.R2383*), exon 4 deletion, and c.5156_5159del (p.K1719Rfs*5). In LAMA2-CMD, splicing variants tended to be associated with a relatively mild phenotype. Nonsense variants were more frequent in LAMA2-CMD (56.9%, 66/116) than in LGMDR23 (21.4%, 3/14), while missense disease-causing variants were more frequent in LGMDR23 (71.4%, 10/14) than in LAMA2-CMD (12.9%, 15/116). Copy number variations were identified in 26.4% of survivors and 50.0% of nonsurvivors, suggesting that copy number variations were associated with lower rate of survival (p = 0.029).

CONCLUSIONS: This study provides better understandings of natural history and genotype-phenotype correlations in LAMA2-related muscular dystrophy, and supports therapeutic targets for future researches.

ABSTRACT

Although buprenorphine is the most frequently used opioid analgesic in common marmosets (Callithrix jacchus), thereis limited information in the literature supporting current dosing regimens used for this species. The purpose of this study was to determine the pharmacokinetic profiles of single-dose buprenorphine HCl administered intramuscularly (IM) at 0.01 mg/kg in 6 adult marmosets (1.8 to 12.8 y old; 2 males, 4 females) and subcutaneously (SQ) at 0.01 mg/kg in 6 adult marmosets(2.3-4.4 y old; 3 males, 3 females) by mass spectrometry. Blood was collected at multiple time points from 0.25 to 24 h from unsedated animals following a hybrid sparse-serial sampling design. The maximal observed plasma concentration of buprenorphine (Cmax) administered IM (2.57 ± 0.95 ng/mL) was significantly higher than administered SQ (1.47 ± 0.61 ng/mL). However, the time to Cmax (Tmax) was not statistically different between routes (17.4 ± 6 min for IM and 19.8 ±7.8 min for SQ). The time of the last quantifiable concentration of buprenorphine was 5 ± 1.67 h for IM compared with 6.33 ± 1.51 h for SQ, which was not statistically different. The mean buprenorphine plasma concentration-time curves were used to propose a dosing frequency of 4 to 6 h for buprenorphine at 0.01 mg/kg IM or SQ based on a theoretical therapeutic plasma concentration threshold of 0.1 ng/mL. Based on the mean pharmacokinetic parameters and plasma-concentration time curves, both IM and SQ routes of buprenorphine at this dose provide a rapid increase in the plasma concentration of buprenorphine above the therapeutic threshold, and may be more effective for acute rather than long-lasting analgesia. Further studies are neededto examine repeated dosing regimens and the efficacy of buprenorphine in common marmosets.

ABSTRACT

OBJECTIVES: To compare mortality, morbidity and neurodevelopment by mode of delivery (MOD) for very preterm births with low prelabour risk of caesarean section (CS).

METHODS: The study was a population-based prospective cohort study in 19 regions in 11 European countries. Multivariable mixed effects models and weighted propensity score models were used to estimate adjusted odds ratios (aOR) by observed MOD and the unit’s policy regarding MOD. Population: Singleton vertex-presenting live births at 24 + 0 to 31 + 6 weeks of gestation without serious congenital anomalies, preeclampsia, HELLP or eclampsia, antenatal detection of growth restriction and prelabour CS for fetal or maternal indications.

RESULTS: Main outcome measures: A composite of in-hospital mortality and intraventricular haemorrhage (grade III/IV) or periventricular leukomalacia. Secondary outcomes were components of the primary outcome, 5 min Apgar score <7 and moderate to severe neurodevelopmental impairment at two years of corrected age. The rate of CS was 29.6% but varied greatly between countries (8.0-52.6%). MOD was not associated with the primary outcome (aOR for CS 0.99; 95% confidence interval [CI] 0.65-1.50) when comparing units with a systematic policy of CS or no policy of MOD to units with a policy of vaginal delivery (aOR 0.88; 95% CI 0.59-1.32). No association was observed for two-year neurodevelopment impairment for CS (aOR 1.15; 95% CI 0.66-2.01) or unit policies (aOR 1.04; 95% CI 0.63-1.70).

CONCLUSIONS: Among singleton vertex-presenting live births without medical complications requiring a CS at 24 + 0 to 31 + 6 weeks of gestation, CS was not associated with improved neonatal or long-term outcomes.

ABSTRACT

INTRODUCTION: Patients with unresectable or recurrent gastric cancer who have an objective response (OR) to nivolumab monotherapy are expected to have a good long-term prognosis. However, the OR rate for nivolumab treatment is low at 11%, and there is a need for biomarkers to predict the treatment response. This study aimed to analyze the significance of systemic inflammation-related variables and clinicopathologic characteristics as predictive markers of response to nivolumab monotherapy in patients with advanced gastric cancer.

METHODS: In this retrospective cohort study, we enrolled 71 consecutive patients who received nivolumab monotherapy for unresectable or recurrent gastric cancer. Receiver operating characteristic curve analysis was performed to determine the cutoff values of systemic inflammation-related variables, predictors of treatment response, and other prognostic factors related to nivolumab therapy. We focused on systemic inflammation-related variables measured before nivolumab induction and 2 weeks after its first administration and performed multivariate analysis to assess whether they could be used as prognostic factors.

RESULTS: Multivariate analysis revealed that a lymphocyte-to-monocyte ratio (LMR) of ≤3.28 after 2 weeks of initial nivolumab treatment (2wLMR) is a statistically significant predictor of treatment response (p = 0.012). The progression-free survival (PFS) rate of patients with liver metastasis was significantly worse than that of the other patients (1-year PFS: 0.0 vs. 24.4%, respectively; p = 0.005). The overall survival (OS) of patients with a low 2wLMR was significantly longer than that in patients with a high 2wLMR (1-year OS: 37.4 vs. 18.9%, respectively; p = 0.022).

CONCLUSIONS: Thus, the 2wLMR could be a useful biomarker to predict response to nivolumab treatment and the prognosis of unresectable and recurrent gastric cancer.

ABSTRACT

BACKGROUND: This study investigates the effect of classical music, music of patients’ own choice, or no music on pain reduction during elective cystoscopy.

OBJECTIVES: The aim of the study was to describe the effect of listening to classical music, music of patients’ own choice, or no music on patient’s pain and satisfaction rates when carrying out an elective cystoscopy and the effect on the assessment capability of the performing urologist.

DESIGN, SETTING, AND PARTICIPANTS: This randomized trial included 127 patients undergoing elective cystoscopy at the Urological Department of the University Clinic of Munich between June 2019 and March 2020. Outcome Measurements and Statistical Analysis: Patients were assigned randomly to 3 groups: group I: listening to standardized classical music (n = 35), group II: listening to music according to the patients’ choice (n = 34), and control group III: no music (n = 44). Prior to cystoscopy, anxiety levels were assessed by the Beck Anxiety Inventory (BAI). The Visual Analog Scale (VAS, range 1-100) was used for a self-assessment of pain, discomfort, and satisfaction. Statistical analysis was done with Spearman’s rank correlation and t-tests.

RESULTS AND LIMITATIONS: The median age was 63 (range 27-91) years. The duration of cystoscopy was 5.7 (1-30) min. Patients had undergone a median of 2.3 cystoscopies in the past. Between giving informed consent and cystoscopy, patients had to wait for a median of 64 (0-260) min. The median VAS pain score was significantly lower in group I at 1.7 and group II at 2.3 versus 5.2 in the control group III (p < 0.001). The control group III had significantly worse pain and patient satisfaction rates compared with groups I and II. Group I had a significant lower VAS pain score than groups II and III (p < 0.001). Classical music also increased the assessment capability of the preforming urologist.

CONCLUSIONS: Listening to music during elective cystoscopy significantly reduces pain and distress and leads to higher patient and surgeon satisfaction. We recommend listening to classical music or music chosen by the patients during outpatient flexible/rigid cystoscopy in daily clinical routine. Patient Summary: In this study, we found that patients who listened to classical music or music of their own choice while undergoing a cystoscopy showed significant reduction of pain and distress.
