Critically ill,tubular injury,delayed early recovery: characteristics of acute kidney disease with renal oxalosis

ObjectsThis study aimed to analyze the clinicopathological features of acute kidney disease (AKD) with renal oxalosis.MethodsData for biopsy-proven AKD with oxalosis diagnosed from Jan 2011 to Oct 2018 was collected. The underlying diseases, dietary habits, clinical and pathological characteristics of newly emerging kidney disease were analyzed. The long-term renal prognosis was observed.ResultsA total of 23 patients were included, comprised of 18 men and 5 women with a mean age of 51.6 ± 15.9 years. The peak Scr was 669.9 ± 299.8 μmol/L, and 95.7% of patients had stage 3 acute kidney injury (AKI). Drug-induced tubulointerstitial nephritis (TIN) was the most common cause (65.2%) of AKD, followed by severe nephrotic syndrome (17.4%). All patients had pathological changes indicating TIN, and 11 patients were complicated with the newly emerging glomerular disease (GD). The risk of oxalosis caused by increased enterogenous oxalate absorption accounted for only 26.1%, and others came from new kidney diseases. The majority (75%) of abundant (medium to severe) oxalosis occurred in patients without GD. There were no significant differences in the score for tubular injury (T-IS) and interstitial inflammation with different severities of oxalosis. Rate of Scr decrease (ΔScr%) at 2 weeks was negatively correlated with the severity of oxalosis (R = −0.542, p = 0.037), score for T-IS (R = −0.553, p = 0.033), and age (R = −0.736, p = 0.002). The decrease in Scr at 4 weeks was correlated with T-IS (R = −0.433), but had no correlation with oxalosis.ConclusionsThe present findings revealed that 95.7% of AKD with secondary renal oxalosis occurred in critically ill patients. AKD from tubular injury was the prominent cause. Severe oxalosis contributed to delayed early recovery of AKD.     

Effect of clinical factors on trajectory of functional performance in patients undergoing hemodialysis

PurposeThis study aimed to investigate the association between clinical factors and temporary changes in functional performance in patients undergoing hemodialysis.MethodsThis was a retrospective, longitudinal observational study conducted from 2015 to 2017. Eight-two patients undergoing hemodialysis in the outpatient clinic were enrolled. Functional performance was measured using the Karnofsky Performance Status (KPS) scale. Collected data for analysis included demographics, laboratory parameters, and KPS scale scores. All participants were grouped into a high KPS cluster and a low KPS cluster based on dynamic changes in KPS scales from 2015 to 2017.ResultsParticipants in the high KPS cluster demonstrated an approximate trend, and those in the low KPS cluster demonstrated a low pattern. By stepwise selection model analysis, age (OR 1.12, 95% CI 1.03–1.23, p = 0.011), serum BUN (OR 1.08, 95% CI 1.02–1.16, p = 0.015), calcium levels (OR 3.24, 95% CI 1.2–8.73, p = 0.02), and beta-2-microglobulin (OR > 1.0, CI >1.00-<1.01, p = 0.031) showed risk for the low KPS cluster. Male sex (OR 0.20, 95% CI 0.04–0.96, p = 0.045) and albumin level (OR 0.02, 95% CI 0–0.4, p = 0.009) showed a low risk for the low KPS cluster.ConclusionsA different trajectory pattern was observed between the high and low KPS clusters in a 3-year period. Risk factors for the low KPS cluster were age, serum BUN, calcium, and beta-2-microglobulin levels. Male sex and serum albumin levels reduced the risk for the low KPS cluster.     

Estrogen and estrogen receptors in kidney diseases

Acute kidney injury (AKI) and chronic kidney disease (CKD) are posing great threats to global health within this century. Studies have suggested that estrogen and estrogen receptors (ERs) play important roles in many physiological processes in the kidney. For instance, they are crucial in maintaining mitochondrial homeostasis and modulating endothelin-1 (ET-1) system in the kidney. Estrogen takes part in the kidney repair and regeneration via its receptors. Estrogen also participates in the regulation of phosphorus homeostasis via its receptors in the proximal tubule. The ERα polymorphisms have been associated with the susceptibilities and outcomes of several renal diseases. As a consequence, the altered or dysregulated estrogen/ERs signaling pathways may contribute to a variety of kidney diseases, including various causes-induced AKI, diabetic kidney disease (DKD), lupus nephritis (LN), IgA nephropathy (IgAN), CKD complications, etc. Experimental and clinical studies have shown that targeting estrogen/ERs signaling pathways might have protective effects against certain renal disorders. However, many unsolved problems still exist in knowledge regarding the roles of estrogen and ERs in distinct kidney diseases. Further research is needed to shed light on this area and to enable the discovery of pathway-specific therapies for kidney diseases.     

Hand grip strength as a predictor of recovery from low back pain in the pregnant women-a prospective study

BackgroundLow back pain (LBP) is a common musculoskeletal problem during pregnancy with an estimated prevalence ranging from 30% to 78%. The symptoms usually disappear gradually after delivery, but some women may have persistent problems even later in their lives. The definite mechanism behind LBP during pregnancy remains unknown. Therefore, the purpose of this study was to investigate whether hand grip strength (HGS), which is a straightforward and reliable indicator of overall muscle strength, is associated with unrecovered LBP after delivery.Methods257 pregnant women who registered at obstetrics units in two tertiary hospitals from January 2016 to June 2017 and meanwhile suffered the LBP during pregnancy were included. They were grouped based on whether they recovered from LBP after delivery (recovery was de?ned as a pain rating of ≤3). The variables such as age, HGS, and education level were recorded and examined for the risk analysis of unrecovered LBP. Also, the Pearson correlation between HGS levels and pain intensities was investigated.ResultsLBP without recovery at two years after delivery was reported among 22.7% of the subjects. Women with increasing age, low HGS (<25 kg), LBP in a previous pregnancy, back pain, sick leave, and a large amount of physical demand (all p < 0.05), were more likely to report LBP without recovery. Besides, there was a significant correlation between HGS values and the intensities of LBP (r = ?0.525; p = 0.003).ConclusionsLow HGS has the highest OR value (adjusted OR = 9.12, P < 0.001) among these factors. The present findings may be used to design and encourage a specific stabilization exercise regime to build well stability of the lumbar spinal column and thus alleviating the LBP.

Multivisceral resection for locally advanced gastric cancer: A retrospective study

BackgroundMultivisceral resection may be the exclusive radical procedure for cT4b gastric cancer patients. However, most surgeons refuse to select surgery because of the theoretical higher mortality, morbidity and poorer prognosis.MethodsWe retrospectively reviewed cT4b gastric cancer patients who underwent surgery from January 1,1997 to December 31,2018. The primary endpoint was overall survival. Short-term results and prognostic values of clinical and pathologic factors were also analyzed.ResultsPatients underwent multivisceral resection had an acceptable mortality and morbidity. The overall 5-year survival rate of multivisceral resection was higher than that of palliative surgery (P < 0.05). And independent prognostic factors of multivisceral resection were R+ resection, extensive lymph node involved (>15), vascular cancer emboli, and postoperative chemotherapy.Conclusions: cT4b gastric cancer patients underwent multivisceral resection experience acceptable mortality and morbidity. The independent prognostic factors for multivisceral resection were completeness of resection, extensive lymph node involvement (>15), vascular cancer emboli, and postoperative chemotherapy.
