ABSTRACT

BACKGROUND: Coronal and sagittal malalignment of the knee are well-recognized risk factors for failure after anterior cruciate ligament (ACL) reconstruction (ACLR). However, the effect of axial malalignment on graft survival after ACLR is yet to be determined.

PURPOSE: To evaluate whether increased tibiofemoral rotational malalignment, namely, tibiofemoral rotation angle (TFA) and tibial tubercle-trochlear groove (TT-TG) distance, is associated with graft failure after ACLR.

STUDY DESIGN: Cohort study; Level of evidence, 3.

METHODS: In this retrospective matched control study of a single center’s database, 151 patients who underwent revision ACLR because of graft failure (ACLR failure group, defined as symptomatic patients with anterior knee instability and an ACL graft tear appreciated on magnetic resonance imaging [MRI] and confirmed during arthroscopic surgery) were compared with a matched control group of 151 patients who underwent primary ACLR with no evidence of failure after ≥2-year follow-up (intact ACLR group). Patients were matched by sex, age, and meniscal injury during primary ACLR. Axial malalignment was assessed on preoperative MRI through the TFA and the TT-TG distance. Sagittal alignment was measured through the posterior tibial slope on MRI. The optimal TFA cutoff associated with graft failure was identified by a receiver operating characteristic curve. The Kaplan-Meier curve with log-rank analysis was performed to evaluate the influence of the TFA on ACLR longevity.

RESULTS: The mean age was 25.7 ± 10.4 years for the ACLR failure group and 25.9 ± 10.0 years for the intact ACLR group. Among all the included patients, 174 (57.6%) were male. In the ACLR failure group, the mean TFA was 5.8°± 4.5° (range, -5° to 16°), while it was 3.0°± 3.3° (range, -3° to 15°) in the intact ACLR group (P < .001). Neither the TT-TG distance nor the posterior tibial slope presented statistical differences between the groups. The receiver operating characteristic curve suggested an optimal TFA cutoff of 4.5° for graft failure (area under the curve = 0.71; P < .001; sensitivity, 68.2%; specificity, 75.5%). Considering this a threshold, patients who had a TFA ≥4.5° had 6.6 times higher odds of graft failure compared with patients with a TFA <4.5° (P < .001). Survival analysis demonstrated a 5-year survival rate of 81% in patients with a TFA <4.5°, while it was 44% in those with a TFA ≥4.5° (P < .001).

CONCLUSION: An increased TFA was associated with increased odds of ACLR failure when the TFA was ≥4.5°. Measuring the TFA in patients with ACL tears undergoing reconstruction may inform the surgeon about additional factors that may require consideration before ACLR for a successful outcome.

ABSTRACT

OBJECTIVE: To evaluate the efficacy of bee venom acupuncture in humeroscapularis (PHS) patients.

METHODS: One hundred and twenty patients diagnosed with PHS were assigned into four groups: BV1 (0.01 mg/kg), BV2 (0.005 mg/kg), BV3 (0.0025 mg/kg), and control group (vitamin B1 plus novocain 3% injection) with 15 d of treatment. The outcomes of the study including visual analogue scale (VAS) score and β-endorphin, inflammatory cytokines including interleukin-10 (IL-10), IL-1β and tumor necrosis factor α (TNF-α) and shoulder function score were assessed at baseline, after 10 and 15 d of treatment.

RESULTS: All four groups reported statistically significant improvement in VAS score, motion range, and shoulder function score ( < 0.01), only the BV3 group showed significant increase of anti-inflammatory (IL-10) and decrease of pro-inflammatory (IL-1β, TNF-α) cytokines after treatment ( < 0.05). The BV3 group presented a significant difference between all outcomes compared to the control and other groups.

CONCLUSION: BV3 groups showed better recovery including reduced pain, improved motor function and normalized inflammatory cytokines than current therapy used in Vietnam and other groups.

ABSTRACT

OBJECTIVE: To observe the clinical efficacy on improving the quality of meibum in patients suffer from dry eye disease (DED) due to meibomian gland dysfunction (MGD) with hyperactivity ofdue todeficiency pattern after being treated with Pinggan Yuyin Qingre formula (, PGYYQR).

METHODS: Totally 120 patients who met the inclusion criteria were included and stratified into three levels according to the level of MGD (1-3), and patients in each level was randomly allocated into the treatment group and control group according to a 1∶1 ratio. Both groups were treated with sodium hyaluronate eye drops, and the treatment group was also given PGYYQR granules. Both groups were treated continuously for eight weeks. The score of the properties of meibomian gland (MG) secretion, the score of the palpebral margins, the average noninvasive tear breakup time (NITBUTav), lipid layer thickness (LLT), and Traditional Chinese Medicine (TCM) syndrome efficacy were compared between the two groups after treatment.

RESULTS: A total of 116 cases were included in the statistical analysis. The differences were statistically significant in the score of the properties of MG secretion, the score of the palpebral margins, and NITBUTav between the two groups after treatment, the treatment group was superior to the control group; there was no evidence of a difference in LLT. In terms of TCM syndrome efficacy, the total effective rate was 84.7% in the treatment group and 50.9% in the control group, with the statistically significant difference. None of the included cases had adverse reactions.

CONCLUSIONS: PGYYQR is effective in improving the quality of meibum, and the tear film stability which thereby relieving the ocular symptoms in MGD-related DED patients with hyperactivity ofdue todeficiency pattern.

ABSTRACT

OBJECTIVE: To explore the mechanism by which Qinghua decoction regulates neuroendocrine inflammation in chronic nonbacterial prostatitis (CNP) model rats and provide an experimental basis for clinical treatment.

METHODS: The rats were randomly divided into six groups: normal control, model, Qianlie Tongyu capsule, low-dose Qinghua decoction, medium-dose Qinghua decoction, and high-dose Qinghua decoction group with six rats in each group. Rats in each group were sacrificed on the 29th day of treatment, and blood and prostate tissues were collected. Serum levels of tumor necrosis factor-alpha and interleukins 1-beta, 6, 8, and 10 (TNF-α and IL-1β, -6, -8, and -10, respectively) were measured using enzyme-linked immunosorbent assay. The pathological changes in the rat prostate tissue in each group were observed under a light microscope. The expression levels of chromogranin A (CgA), nerve growth factor (NGF), and tyrosine kinase A (TrkA) were detected using reverse transcription quantitative polymerase chain reaction. Western blotting was used to detect protein expression of CgA, NGF, and TrkA.

RESULTS: In the model group, the prostate capsule membrane and stroma were significantly dilated with more inflammatory cells infiltrating the stroma and perivessels. TNF-α, IL-1β, -6, and -8, CgA, NGF, and TrkA levels increased, whereas the content of IL-10 decreased, which was statistically significant compared to that in the normal control group ( < 0.05). Prostate tissue cells in the high-dose group were neatly arranged with no obvious inflammatory cell infiltration. When compared with the model group, the high-dose Qinghua decoction group showed a significant improvement in these indices ( < 0.05).

CONCLUSION: Qinghua decoction led to inhibition of pathological changes in the prostate tissue of rats with CNP, regulation of inflammatory cytokine expression, and inhibition in the expression of CgA, NGF, and TrkA. This mechanism may be primarily related to regulation of the CgA/NGF/TrkA signaling pathway mediated by various inflammatory factors.

ABSTRACT

OBJECTIVE: To systematically evaluate the efficacy and safety of Angong Niuhuang pill (, ANP) in the treatment of acute stroke. This can provide ideas and basis for the treatment of this disease with integrated Traditional Chinese and Western Medicine.

METHODS: Randomized controlled trials (RCTs) of China National Knowledge Infrastructure Database, Wanfang Database, Chinese BioMedical Literature Database, PubMed, Embase, and the Cochrane Library were searched from the establishment to March 2022. Two researchers screened the literature and extracted the data according to inclusion and exclusion criteria. Meta-analysis was performed using RevMan 5.3 software.

RESULTS: A total of 28 RCTs were included, including 2745 patients in the acute stage of stroke (1375 in the experimental group and 1370 in the control group). Meta-analysis showed that compared with conventional treatment, combined treatment with ANP could improve the effective rate of acute stroke patients [relative risk () = 1.26, 95% confidence interval () (1.21, 1.31)], Glasgow Coma Scale scores [mean difference () = 2.01, 95% (1.04, 2.98)], Mini-mental State Examination scores [ = 4.79, 95% (2.22, 7.37)], Activities of Daily Living scores [ = 15.70, 95% (14.05, 17.36)] and the Barthel index scores [ = 13.89, 95% (12.12, 15.65)], reduce National Institute of Health stroke scale scores [ = -3.90, 95% (-4.96, -2.84)] and serum brain natriuretic peptide [ = -38.50, 95% (-46.85, -30.15)]. In terms of safety, the incidence of adverse reactions showed no statistical differences between the two groups [ = 0.71, 95% (0.43, 1.15), = 0.16], and no serious adverse reactions/events were observed, indicating a good safety.

CONCLUSIONS: Existing clinical research evidence shows that ANP has good efficacy and safety in the treatment of acute stroke, which can provide a basis for the treatment of integrated Traditional Chinese and Western Medicine. However, the quality of included research methodology needs to be improved, and the above conclusions need to be verified by more high-quality studies.

ABSTRACT

Infectious diseases spread rapidly, and epidemiological surveys are vital to detect high-risk transmitters and reduce transmission rates. To enhance efficiency and reduce the burden on epidemiologists, an automatic tool to assist with epidemiological surveys is necessary. This study aims to develop an automatic epidemiological survey to predict the influence of COVID-19-infected patients on future additional infections. To achieve this, the study utilized a dataset containing interaction information between confirmed cases, including contact order, contact times, and movement routes, as well as individual properties such as symptoms. Graph neural networks (GNNs) were used to incorporate interaction information and individual properties. Two variants of GNNs, graph convolutional and graph attention networks, were utilized, and the results showed that the graph-based models outperformed traditional machine learning models. For the area under the curve, the 2nd, 3rd, and 4th order spreading predictions showed higher performance by 0.200, 0.269, and 0.190, respectively. The results show that the contact information of an infected person is crucial data that can help predict whether that person will affect future infections. Our findings suggest that incorporating the relationships between an infected person and others can improve the effectiveness of an automatic epidemiological survey.

ABSTRACT

The Bouba-Kiki effect is the systematic mapping between round/spiky shapes and speech sounds (“Bouba”/”Kiki”). In the size-weight illusion, participants judge the smaller of two equally-weighted objects as being heavier. Here we investigated the contribution of visual experience to the development of these phenomena. We compared three groups: early blind individuals (no visual experience), individuals treated for congenital cataracts years after birth (late visual experience), and typically sighted controls (visual experience from birth). We found that, in cataract-treated participants (tested visually/visuo-haptically), both phenomena are absent shortly after sight onset, just like in blind individuals (tested haptically). However, they emerge within months following surgery, becoming statistically indistinguishable from the sighted controls. This suggests a pivotal role of visual experience and refutes the existence of an early sensitive period: A short period of experience, even when gained only years after birth, is sufficient for participants to visually pick-up regularities in the environment, contributing to the development of these phenomena.

ABSTRACT

Methylmercury (MeHg) is a microbially produced neurotoxin derived from inorganic mercury (Hg), which accumulation in rice represents a major health concern to humans. However, the microbial control of MeHg dynamics in the environment remains elusive. Here, leveraging three rice paddy fields with distinct concentrations of Hg (Total Hg (THg): 0.21-513 mg kg^-1 dry wt. soil; MeHg: 1.21-6.82 ng g^-1 dry wt. soil), we resorted to metagenomics to determine the microbial determinants involved in MeHg production under contrasted contamination settings. We show that Hg methylating Archaea, along with methane-cycling genes, were enriched in severely contaminated paddy soils. Metagenome-resolved Genomes of novel putative Hg methylators belonging to Nitrospinota (UBA7883), with poorly resolved taxonomy despite high completeness, showed evidence of facultative anaerobic metabolism and adaptations to fluctuating redox potential. Furthermore, we found evidence of environmental filtering effects that influenced the phylogenies of not only hgcA genes under different THg concentrations, but also of two housekeeping genes, rpoB and glnA, highlighting the need for further experimental validation of whether THg drives the evolution of hgcAB. Finally, assessment of the genomic environment surrounding hgcAB suggests that this gene pair may be regulated by an archaeal toxin-antitoxin (TA) system, instead of the more frequently found arsR-like genes in bacterial methylators. This suggests the presence of distinct hgcAB regulation systems in bacteria and archaea. Our results support the emerging role of Archaea in MeHg cycling under mining-impacted environments and shed light on the differential control of the expression of genes involved in MeHg formation between Archaea and Bacteria.

ABSTRACT

Tuberculosis, an airborne disease, is the deadliest human infectious disease caused by one single agent. The African region is among the most affected and most burdensome area in terms of tuberculosis cases. In this paper, we modeled the number of new cases of tuberculosis for 2000-2021 by integer time series. For each African country, we fitted twenty different models and selected the model that best fitted the data. The twenty models were mostly based on the number of new cases following either the Poisson or negative binomial distribution with the rate parameter allowed to vary linearly or quadratically with respect to year. The best fitted models were used to give predictions for 2022-2031.

ABSTRACT

BACKGROUND: Youth is a vulnerable period. To classify lifestyle behaviors and its relationship with health-related outcomes of Spanish children and adolescents.

METHODS: Cross-sectional study including 3261 children aged 7.5-17.5 y (52.8% females). Physical activity (PA), screen-time, sleep time, adherence to Mediterranean diet (MD), weight status (WS) by validated methods. Cluster analysis was run considering chronological age.

RESULTS: Six clusters were identified: C1: high screen time, low adherence to MD and sleep time (n = 431,13.20%); C2: high WS, medium adherence to MD,high sleep time, and low screen time (n = 466,14.30%); C3: young group with low screen time and high PA, adherence to MD and sleep (n = 537,16.40%); C4: worst profile regarding adherence to MD, PA, WS and sleep time (n = 609,18.70%); C5: low screen time and PA, high sleep time (n = 804,24.70%); C6: high PA and screen time, low WS (n = 414,12.70%). Mean absolute values were statistically different among PA levels, screen and sleep time, adherence to MD, age, and WS (all p < 0.001).

CONCLUSIONS: The most prevalent pattern was low levels of PA, MD, and screen time, and high sleep time. The second most prevalent was characterized by very low levels of PA, sleep time, and adherence to MD, and high screen time, and WS in adolescents.

IMPACT STATEMENT: The main identified lifestyle behavior was poor physical activity, low adherence to Mediterranean Diet and high screen and sleep time. Children should increase physical activity levels, adherence to Mediterranean diet, decrease screen and sleep the appropriate hours per day. Families, schools, and medical communities must work together to gloss over present and future diseases. Sleep time had not been previously included in cluster analysis with physical activity, sedentary behaviors, obesity, and nutritional status, thus the present data open a new perspective in Spanish population. Health policies should focus on promoting physical activity, Mediterranean diet, adequate sleep and reducing screen time.
