The international prevalence involving weakening of bones on earth: an extensive methodical review and also meta-analysis.
HIF-PHI (hypoxia-inducible factor prolyl hydroxylase inhibitor) was developed to improve renal anemia. This study was to evaluate the efficiency and safety of HIF-PHI in patients with non-dialysis-dependent chronic kidney disease (NDD-CKD).

The literature was extracted from PubMed, EMBASE, the Cochrane Central Register of Controlled Trials, and the Wanfang database. Statistical tests and forest plots were depicted by Review Manager Version 5.3. The primary outcome was a change in hemoglobin level from baseline (ΔHb). Secondary outcomes were changes in ferritin (ΔFerritin), hepcidin (ΔHepcidin), and transferrin saturation from baseline (ΔTSAT), and adverse events (AEs). This study is registered with PROSPERO (registration number CRD42020199656).

Ten trials were included. The results showed that HIF-PHI improved the ΔHb [SMD 3.03 (95% CI 2.10, 3.96), P < 0.00001] in NDD patients. HIF-PHI reduced hepcidin levels in the NDD patients [SMD - 1.44 (95% CI - 2.19-0.70), P = 0.0002]. ΔFerritin values were reduced significantly in the HIF-PHI group [SMD - 1.08 (95% CI - 1.63-0.53), P = 0.0001]. However, ΔTSAT values showed no significant difference in the HIF-PHI group compared to the placebo group [SMD - 0.23 (95% CI - 0.66-0.21), P = 0.31]. In the safety assessment, HIF-PHI did not increase adverse events significantly [RR 0.98 (95% CI 0.88-1.10), P = 0.74].

HIF-PHI improves renal anemia and iron utilization disorder in NDD-CKD patients, without significantly more adverse events.

To evaluate the effect of masturbation on the spontaneous expulsion of distal ureteral stones 5-10mm in size.

A total of 128 men with distal ureteral stones were randomly divided into 3 groups. All patients received standard medical therapy. Patients in group 1 (n = 43) were instructed to masturbate at least 3-4 times a week, patients in group 2 (n = 41) received tamsulosin 0.4mg/day, and patients in group 3 (controls, n = 44) received standard medical therapy alone. Rates of expulsion, need for analgesic, and ureterorenoscopic lithotripsy were compared between the groups.

The mean ages of the patients in groups 1, 2, and 3 were 37 ± 5.0, 37.6 ± 4.6, and 38.4 ± 6.8years, respectively (p = 0.7). The mean stone size in each group was 6.93 ± 1.1mm, 7.1 ± 0.9mm, and 6.87 ± 1.1mm, respectively (p = 0.4). Spontaneous passage rates in groups 1, 2, and 3 were 81.4%, 80.5%, and 43.2%, respectively, and were significantly higher in group 1 (p = 0.001) and group 2 (p = 0.001) when compared with group 3. Analgesic cantly lower in the tamsulosin group than in the control group (p = 0.004) CONCLUSION Masturbation and tamsulosin increased the spontaneous passage of distal ureteral stones 5-10 mm in size. Masturbating at least 3-4 times a week was as effective as tamsulosin. Masturbation and tamsulosin also reduced the need for ureterorenoscopic lithotripsy.Coronavirus disease 2019 (COVID-19) appears to be associated with increased arterial and venous thromboembolic disease. These presumed abnormalities in hemostasis have been associated with filter clotting during continuous renal replacement therapy (CRRT). We aimed to characterize the burden of CRRT filter clotting in COVID-19 infection and to describe a CRRT anticoagulation protocol that used anti-factor Xa levels for systemic heparin dosing. Multi-center study of consecutive patients with COVID-19 receiving CRRT. Primary outcome was CRRT filter loss. Sixty-five patients were analyzed, including 17 using an anti-factor Xa protocol to guide systemic heparin dosing. Fifty-four out of 65 patients (83%) lost at least one filter. Median first filter survival time was 6.5 [2.5, 33.5] h. There was no difference in first or second filter loss between the anti-Xa protocol and standard of care anticoagulation groups, however fewer patients lost their third filter in the protocolized group (55% vs. 93%) resulting in a longer median third filter survival time (24 [15.1, 54.2] vs. 17.3 [9.5, 35.1] h, p = 0.04). The rate of CRRT filter loss is high in COVID-19 infection. An anticoagulation protocol using systemic unfractionated heparin, dosed by anti-factor Xa levels is reasonable approach to anticoagulation in this population.The development of a stable nanobioconjugate based on gold nanoparticles (AuNPs) linked to single-strand DNA (ssDNA) is reported for amplification of the electrochemical signal of a Zika virus (ZIKV) genetic material-based bioassay, with high sensitivity. The genosensor was assembled either at a screen-printed gold electrode (SPAuE) or a screen-printed carbon electrode decorated with hierarchical gold nanostructures (SPCE/Au), with Ru3+ as an electrochemical reporter. The genosensor response, interrogated by differential pulse voltammetry (DPV) at the transient current density, was linear from 10 to 600 fM and from 500 fM to 10 pM of the target, with a sensitivity of 2.7 and 2.9 μA cm-2 M-1 and a limit of detection of 0.2 and 33 fM at the SPAuE and SPCE/Au, respectively. The resultant genosensor detected ZIKV genetic material in raw serum samples from infected patients, with no sample pretreatment in a polymerase chain reaction amplification-free assay. The proposed ultrasensitive nanobioconjugate-based system offers a step forward to the diagnosis of the ZIKV, closer to the patient, and holds the potential for signal amplification in biosensing of a myriad of applications.Graphical abstract.While technical considerations in lung transplantation for Kartagener syndrome have been discussed, little information is available about the postoperative morphological changes of the grafted lungs. Herein, we discuss both the technical aspects and postoperative morphological adaptation of the grafted lungs in a case of Kartagener syndrome. A 46-year-old male patient with Kartagener syndrome underwent bilateral cadaveric lung transplantation. The right arterial anastomosis for transplantation of the size-matched grafts required technical elaboration. After the transplantation, we found a free space in the cardiac notch of the left lung and partial collapse of the lower lobe of the right lung due to dextrocardia. Follow-up computed tomography performed on day 42 after the transplantation demonstrated resolution of the atelectasis and morphological adaptation of the grafts into the recipient's chest cavity with dextrocardia. find more Considering such early morphological adaptation of size-matched grafts, lobar reduction could be avoided in lung transplantation for Kartagener syndrome.
Meta-analysis was used to determine the association between rs3751143 polymorphism of P2RX7 gene and the risk of chronic lymphocytic leukemia (CLL).

Search for published articles about the association between the rs3751143 and CLL in PubMed, MEDINE, Web of Science, and Embase databases, with a calculated odds ratio of (OR) and 95% confidence interval (95%CI).

A total of 1184 cases and 1725 controls in 8 studies were pooled together for evaluation of the overall association between rs3751143 and risk of CLL. Allele model (A vs C, p = 0.16, OR = 0.85, 95%CI = 0.71-1.17), homozygous model (AA vs CC, p = 0.07; OR = 0.78, 95%CI = 0.84-1.08), and heterozygous model (AC vs CC, p = 0.76; OR = 0.85; 95%CI = 0.68-0.79) did not show decreased risk of developing CLL. Similarly, dominant model (AA + AC vs. CC p = 0.58; OR = 1.10, 95%CI = 0.69-1.75), and recessive model (AA vs AC + CC, p = 0.21, OR = 1.18, 95%CI = 0.70-1.99) failed to show decreased risk of developing CLL. However, in familial, heterozygous model (AC vs. CC p = 0.0006, OR = 0.64, 95%CI = 0.67-1.50) and recessive model (AA vs. AC + CC p = 0.0017; OR = 1.02, 95%CI = 0.73-2.35) indicated the association between the inheritance of rs3751143 and the risk of developing CLL. In the overall survival prognosis, no significant association between rs3751143 and CLL was detected with relatively high heterogeneity.

Our pooled data indicates that there is a correlation between the inheritance of rs3751143 and the risk of CLL in familial.

Computational modeling provides a helpful solution for obtaining estimates of in vivo loads. A multiscale model was constructed by combining musculoskeletal and finite element (FE) models of the lumbar spine to determine tissue loading during daily activities. Three-dimensional kinematic and ground reaction force data were collected from participants with ([Formula see text]) and without ([Formula see text]) a unilateral transtibial amputation (TTA) during 5 sit-to-stand trials. We estimated tissue-level load transfer from the multiscale model by controlling the FE model with intervertebral kinematics and muscle forces predicted by the musculoskeletal model. Annulus fibrosis stress, intradiscal pressure (IDP), and facet contact forces were calculated using the FE model. Differences in whole-body kinematics, muscle forces, and tissue-level loads were found between participant groups. Notably, participants with TTA had greater axial rotation toward their intact limb ([Formula see text]), greater abdominal muscle activity ([Formula see text]), and greater overall tissue loading throughout sit-to-stand ([Formula see text]) compared to able-bodied participants. Both normalized (to upright standing) and absolute estimates of L4-L5 IDP were close to in vivo values reported in the literature. The multiscale model can be used to estimate the distribution of loads within different lumbar spine tissue structures and can be adapted for use with different activities, populations, and spinal geometries.
The relationship between cervical degenerative pathology and total knee arthroplasty (TKA) revision rates is not well understood. The aim of the study was to determine whether cervical spine degenerative diseases have a role in complications following TKA within 2years.

Data were collected from the Humana insurance database using the PearlDiver Patient Records Database from 2007-2017. Patients who had a primary TKA were identified using Current Procedural Terminology (CPT) code 27,447, and patients with degenerative cervical disease were identified using CPT and International Classification of Diseases (ICD) codes. Data on patients' demographics, comorbidities and postoperative complications were recorded and analyzed with univariate and multivariate analysis with significance set at p < 0.05. A Kaplan-Meier analysis was conducted to estimate the 1- and 2-year rates of survival free from revision.

A total of 81,873 patients were included in this study. Following multivariate analysis, cervical spine degenerative disease patients were at increased risk of all-cause revision surgery following 1year (OR 1.342 95% CI 1.149-1.569; p < 0.001) and 2year (OR 1.338; 95% CI 1.184-1.512; p < 0.001). At 2years, patients with cervical spine degenerative disease had a survival rate of 97.7%, while the survival rate was 99.2% among the non-cervical degenerative cohort.

Based on these results, patients with cervical spine degenerative pathology should be counseled that their spinal pathology may impair outcomes following TKA.
