RESUMEN

This study aimed to evaluate the effectiveness of ICI of platelet-rich plasma (PRP) in addition to daily oral tadalafil intake in diabetic erectile dysfunction (ED) patients non-responding to PDE5 inhibitors. Overall, 48 patients complaining of ED non-responding to on-demand PDE5 inhibitors were allocated into 2 equal groups, diabetics and non-diabetics that were given a daily dose of 5 mg tadalafil plus vardenafil 20 mg on demand during the study besides being subjected to 3 doses of ICI of PRP, 4 weeks apart. Responses to on-demand PDE5 inhibitors, International index of erectile function-5 (IIEF-5) score, erection hardness scores (EHS) and pharmaco-dynamic duplex studies were assessed. After PRP injections, 33% and 50% of cases were satisfied with on-demand PDE5 inhibitors, respectively, whereas 41% and 66% of them showed improved EHS response. Compared with baseline scores, the mean IIEF-5 scores were significantly improved after PRP therapy in the diabetic ED group (12.1 vs. 8.04, p = 0.003) as well as in the non-diabetic ED group (14.8 vs. 10.2, p = 0.001) linked to pharmaco-penile duplex readings. Both good and fair diabetic control exhibited significant responses to ICI therapy of PRP compared with bad controlled cases. The significant improvement included; the IIEF-5 score increase (86.7%, 126% vs. 16.1%), improved EHS as well as penile duplex readings. Baseline HbA1C demonstrated a significant negative correlation with IIEF-5 score before (p = 0.019) and after PRP therapy (p = 0.002) respectively. It could be concluded that ICI of PRP could be an effective therapy for treating ED patients non-responding to on-demand oral PDE5 treatment.

RESUMEN

Peripartum cardiomyopathy is a form of idiopathic systolic heart failure which occurs during the end of pregnancy or the early post-partum in the absence of an identifiable etiology. The exact pathogenesis remains unknown, and the incidence is higher in African ancestry, multiparous and hypertensive women, or older maternal age. Delay in diagnosis is common, mainly because symptoms of heart failure mimic those of normal pregnancy. Echocardiography showing decreased myocardial function is at the center of the diagnosis. Management relies on the general guidelines of management of other forms of non-ischemic cardiomyopathy; however, special attention should be paid when choosing medications to ensure fetal safety. Outcomes can be variable and can range from complete recovery to persistent heart failure requiring transplant or even death. High rates of relapse with subsequent pregnancies can occur, especially with incomplete myocardial recovery. Additional research about the etiology, experimental drugs, prognosis, and duration of treatment after recovery are needed.

RESUMEN

Erectile dysfunction (ED) is a common condition with a significant impact on the quality of life. Regenerative medicine maladies are intended to repair or replace damaged tissues and organs through different therapeutic mechanisms. Our aim was to study the effect of intra-corporeal injection (ICI) of platelet-rich plasma (PRP) in ED patients. Thirty-four patients' erectile function was evaluated by filling up an abridged form of the international index of erectile function (IIEF-5) before and after PRP therapy. ICI of PRP was done once per week for 2 months. All patients were prescribed PDE5Is for one month after PRP therapy. Penile haemodynamics was assessed using 20 µg of PGE1 before and 3 months after initiating PRP therapy. Interestingly, our study had shown that there was a statistically significant difference in the IIEF-5 score after ICI of PRP (-5.5, ±5.2, p=<0.001). Furthermore, in multiple logistic regression model for PRP responsiveness, smoking and IIEF score before PRP were the only significant independent variables (p = .040, p = .023 respectively). PRP injection for ED patients may be a promising modality as well as baseline IIEF-5, and smoking status can be used as predictors for a satisfactory response to PRP in such patients.

RESUMEN

BACKGROUND: We examined the clinical and functional outcomes of the simultaneous anterior distal femoral 8-plate hemiepiphysiodesis (ADF8PH) and hamstring release, for fixed knee flexion deformity in children with neuromuscular disease. To our knowledge, no published evidence is available that reports the outcomes of this combined techniques. METHODS: Electronic medical records were retrospectively reviewed for 19 consecutive children who underwent bilateral ADF8PH and concomitant hamstrings release in our institution from 2012 to 2019. Relevant demographics, Gross Motor Functional Classification Score and preoperative and postoperative knee flexion contractures and popliteal angles were documented. RESULTS: The average age at the time of operation was 12±2.1 years. There were 15 males and 4 females. Diagnoses included cerebral palsy (n=16), Cornelia de Lange syndrome (n=1), hereditary spastic paraplegia type 56 (n=1) and fructose-1,6 bisphosphonate aldose B deficiency (n=1). Mean length of follow-up was 3.8 years (range: 1.5 to 7 y). Mean fixed knee flexion deformity improved from 28.9 to 13.4 degrees (P<0.001) at an average correction rate of 0.94 degrees per month. Mean popliteal angle improved from 81.8 to 44.4 degrees (P<0.001) in the early postoperative phase and to 51.8 degrees (P<0.001) in latest clinic review. Mean time to correction was 18.9 months. The agreed treatment goals of maintaining or promoting the use of standing frame and spinal/postural symmetry was attained in 18 patients (94.7%). Postoperative knee pain was reported in 2 cases (10.5%). We report 2 complications; 1 case of neurapraxia and 1 case of sepsis because of respiratory infection. CONCLUSION: Simultaneous bilateral ADF8PH with hamstrings release is a promising effective technique for correction of knee flexion contractures in skeletally immature individuals with neuromuscular disabilities. Our findings demonstrate improvement in clinical outcomes and maintaining functional outcomes, indicating the validity of this approach as a satisfactory, less invasive alternative in the management of this deformity. LEVEL OF EVIDENCE: Level IV-therapeutic study.

RESUMEN

BACKGROUND: Among heart failure patients with implantable cardioverter defibrillators (ICDs), monomorphic ventricular tachycardia (MMVT) failing antitachycardia pacing (ATP) and terminated by shock renders higher mortality as compared to MMVT terminated by ATP only. It is unknown if the higher mortality in ATP failure reflects decompensated heart failure. OBJECTIVE: It was the purpose of the present study to determine if ICD heart failure diagnostics can predict the failure of ATP and the need to shock to terminate MMVT. METHODS: This was a single-center retrospective review of 103 consecutive patients with Medtronic ICDs who had MMVT and received ICD therapy. Heart failure diagnostics preceding each MMVT event were reviewed including atrial fibrillation burden, patient activity, night heart rate, heart rate variability, Optivol® fluid index, and MMVT heart rate. RESULTS: A total of 452 MMVT events were analyzed, of which 23% required shock. Compared to MMVT that responded to ATP, MMVT that failed ATP and required shock had significantly faster heart rates and higher atrial fibrillation burden. Patient activity, night heart rate, heart rate variability, and OptiVol® fluid index were similar between ATP responsive MMVT events and those that failed ATP. In a multivariate analysis adjusting for baseline characteristics, higher atrial fibrillation burden and lower patient activity were associated with ATP failure and shock termination. CONCLUSION: Device diagnostics associated with decompensated heart failure identified MMVT events that failed ATP and necessitated shock.

RESUMEN

BACKGROUND: Penile length and girth have long been sources of anxiety for men. OBJECTIVES: The authors sought to measure satisfaction with intercourse and erectile function 3 and 6 months after girth augmentation in patients with semi-rigid penile implants who received autologous fat injections. METHODS: Thirty married participants in Egypt were recruited and divided into 2 groups between January 2016 and August 2017. Fifteen patients who underwent semi-rigid penile implant insertion and 15 controls all received autologous fat injections and were followed-up for 3 and 6 months. RESULTS: Median penile girth increased significantly in both groups, although fat loss was noted after 6 months. There was a positive correlation between the amount of fat injected and the change in penile girth measured 6 months after the procedure in the controls. CONCLUSIONS: Autologous fat transfer is a simple and safe procedure that can be used to augment penile girth in patients whose girth is less than 11.5 cm after penile prosthesis insertion.

RESUMEN

In the cow, cryopreserved semen is inseminated into the uterus, and most of sperm are removed by backflow and phagocytes. Nevertheless, the mechanism responsible for sperm phagocytosis is unclear. Here, we used cultured bovine uterine epithelial cells (BUECs) to investigate the uterine response to sperm and the mechanism that activates polymorphonuclear neutrophils (PMNs). BUEC monolayers were co-cultured with different numbers of washed sperm obtained from cryopreserved semen (104 , 105 , and 106 sperm/ml) for 3 hr. Sperm dose-dependently up-regulated IL8 (Interleukin 8). Sperm at 106 /ml increased mRNA expression of TNFA (Tumor necrosis factor alpha), IL1B (Interleukin 1B), NFKB2 (Nuclear factor kappa B2), and C3 (Complement factor 3), as well as PGES (Prostaglandin E synthase) expression and PGE2 release. Live sperm, but not dead sperm, attached to BUECs, and dead sperm did not induce an acute inflammatory response. Time-dependent effects were evaluated by co-culture of 106 /ml washed sperm with BUECs for 0, 1, 3, and 6 hr. The number of detached sperm increased gradually toward 6 hr. Maximum mRNA expression of IL8, TNFA, IL1B, and NFKB2 was induced at 3 hr, while C3 continued to increase toward 6 hr. Sperm did not stimulate mRNA expression of anti-inflammatory cytokines TGFB1 (Transforming growth factor beta 1) or IL10 (Interleukin 10). Medium conditioned by sperm co-incubated with BUECs stimulated PMNs phagocytosis of sperm in vitro. Fresh media supplemented with low levels of IL1B, TNFA, and PGE2 up-regulated sperm phagocytosis by PMNs as well. In conclusion, our findings strongly suggest that the active sperm attach to BUECs and trigger uterine local innate immunity with induction of a pro-inflammatory response that enhances sperm phagocytosis by PMNs.

RESUMEN

BACKGROUND: A head that is "clinically cold welded" to a stem is one of the commonest reasons for unplanned removal of the stem. It is not clear which hip designs are at greatest risk of clinical cold welding. METHODS: This was a case-control study of consecutively received hip implant retrievals; we chose the design of hip that had the greatest number of truly cold-welded heads (n = 11). For our controls, we chose retrieved hips of the same design but without cold welding of the head (n = 35). We compared the clinical variables between these 2 groups using nonparametric Mann-Whitney tests to investigate the significance of differences between the cold-welded and non-cold-welded groups. RESULTS: The design that most commonly caused cold welding was a combination of a Ti stem and Ti taper: 11 out of 48 (23%) were truly cold welded. Comparison of the clinical data showed that no individual factor could be used to predict this preoperatively with none of the 4 predictors tested showing any significance: (1) time to revision (P = .687), (2) head size (P = .067), (3) patient age at primary (P = .380), and (4) gender (P = .054). CONCLUSION: We have shown that clinical cold welding is most prevalent in Ti-Ti combinations of the stem and taper; approximately 25% of cases received at our center were cold welded. Analysis of clinical variables showed that it is not possible to predict which will be cold welded preoperatively. Surgeons should be aware of this potential complication when revising a Ti-Ti stem/head junction.

RESUMEN

Four new sesquiterpene lactones, 4α-hydroxy-guaia-10(14),11(13)-diene-12,6α-olide (1), 4α-hydroxy-9α-acetoxy-guaia-1(10),2-diene-12,6α-olide (4), 4α-hydroxy-9ß-acetoxy-guaia-1(10),2-diene-12,6α-olide (5), and 1α,4α-dihydroxy-9α-acetoxy-guaia-10(14),2-diene-12,6α-olide (6), were isolated from the aerial parts of Anthemis scrobicularis. Their structures were elucidated on the basis of their IR, NMR, and MS spectroscopic data. In addition, two known sesquiterpene lactones micheliolide (2) and achillin (3) were also isolated. The cytotoxicity of some of the isolated compounds was tested against HCT 116, HepG-2, and MCF-7 cell lines. Micheliolide and 4α-hydroxy-guaia-10(14),11(13)-diene-12,6α-olide showed pronounced inhibitory activity while 4α-hydroxy-9α-acetoxy-guaia-1(10),2-diene-12,6α-olide showed weak activity.

RESUMEN

The current research was designed to evaluate the phytochemical contents, cytotoxic and antimicrobial activity of Emex spinosa extracts. The different plant extracts and Aloe-emodin glucoside were screened using the colorimetric MTT method (3-(4,5-dimethylthiazo-2-yl)-2,5-diphenyl- tetrazolium bromide) assay to test their in vitro cytotoxic activity against HepG2, MCF-7, Caco-2 and HCT. The clinically used anticancer drug doxorubicin was used as standard for comparative purposes. Anthraquinones (Aloe-emodin-O-glucoside, Emodin and nataloin (1, 2, 8-trihydroxy, 6-methyl, 10-anthrone-C-glucoside) together with ß-sistosterol and ß-sitisterol-O-ß-D-glucoside were isolated from Emex spinosa. Aloe-emodin glucoside together with four fractions from this plant were evaluated for their anticancer and antimicrobial activities. Aloe-emodin glucoside showed anticancer activity against HCT, HepG-2, MCF-7 and Caco-2 cell lines. The total ethanol extract of E. spinosa and diethyl ether, chloroform, ethyl acetate and butanol fractions shown antibacterial activity against Staphylococcus aureus, Streptococcus pyogenes and Bacillus subtilis.

RESUMEN

OBJECTIVES: The study examined the impact of long term COVID-19 infection on the patients' erectile function and anxiety and depression in the same patients as well as the impact of daily tadalafil 5 mg supplementation on their erectile function. METHODS: Recovered 114 men were evaluated by the validated Arabic version of the international index of erectile function (ArIIEF-5) and the Arabic versions of the patient health questionnaire-9 (PHQ-9) and the generalized anxiety disorder-7 (GAD-7) at time of presentation, at 3 months and at 6 months, respectively. Forty recovered patients who still complained of ED received tadalafil 5 mg daily for 2 months then were evaluated again at 3 and 6 months by penile duplex, the Arabic versions of the patient health questionnaire-9 (PHQ-9) and the generalized anxiety disorder-7 (GAD-7) at the same periods, respectively. RESULTS: At the time of presentation, there was a positive correlation between the severity of COVID-19 infection, ArIIEF-5 and PHQ-9 (r = 0.249, p = 0.008; r = 0.241, p = 0.010, respectively). Most of the patients showed normal penile duplex parameters. There were 40 ED patients at presentation, 5 ED patients at 3 months and 3 ED patients at 6 months, respectively. CONCLUSIONS: ED in COVID-19 patients who were not suffering from chronic illnesses before the affection, is primarily psychological and completely responsive to tadalafil.

RESUMEN

Periprosthetic acetabular fractures are rare but potentially devastating complications of total hip arthroplasty. As the number of total hip arthroplasties performed annually increases, so has the incidence of periprosthetic fractures, with the topic being spotlighted more frequently in the orthopaedic community. There is a particular sparsity of literature regarding periprosthetic acetabular fractures, with periprosthetic femoral fractures after total hip arthroplasty being traditionally far more commonly reported. This article aims to provide an up-to-date review of the epidemiology, risk factors, diagnostic challenges, classifications, and management strategies for periprosthetic acetabular fractures after total hip arthroplasty.

RESUMEN

BACKGROUND: Studies evaluating the role of midodrine as an adjunctive therapy to liberate patients with shock from intravenous (IV) vasopressors have yielded mixed results. The aim of our study was to evaluate the efficacy and safety of midodrine as an adjunctive therapy to liberate patients with shock from IV vasopressors. METHODS: Electronic searches of the MEDLINE, EMBASE, and Cochrane databases through April 2022 for randomized controlled trials (RCTs) that evaluated the use of midodrine versus control in patients with shock and a low dose of IV vasopressors. The primary outcome was total IV vasopressor time, while the secondary outcomes included time-to-IV vasopressor discontinuation, IV vasopressor restart, intensive care unit (ICU) length of stay (LOS), hospital LOS, and incidence of bradycardia. RESULTS: The final analysis included four RCTs with a total of 314 patients: 158 in the midodrine group and 156 in the control group, with a weighted mean age of 64 years (54.2% men). There was no significant difference in the total IV vasopressor time between the midodrine and control groups (standardized mean difference [SMD] - 0.53; 95% confidence interval [CI] - 1.38 to 0.32, p = 0.22; I2 = 92%). Also, there were no significant differences between the two groups in the time-to-IV vasopressor discontinuation (SMD - 0.05; 95% CI - 0.57 to 0.47, p = 0.09), IV vasopressor restart (19.3 vs. 28.3%; risk ratio [RR] 0.74; 95% 0.25-2.20, p = 0.59), ICU LOS (SMD - 0.49; 95% CI - 1.30 to 0.33, p = 0.24), and hospital LOS (SMD 0.01; 95% CI - 0.27 to 0.29, p = 0.92). However, compared with the control group, the midodrine group had a higher risk of bradycardia (15.3 vs. 2.1% RR 5.56; 95% CI 1.54-20.05, p = 0.01). CONCLUSIONS: Among patients with vasopressor-dependent shock, midodrine was not associated with early liberation of vasopressor support or shorter ICU or hospital length of stay. Adding midodrine increased the risk of bradycardia. Further large RCTs are needed to better evaluate the efficacy and safety of midodrine in liberating patients from IV vasopressors.

RESUMEN

BACKGROUND: Scarce data exist on the evolution of device-related thrombus (DRT) after left atrial appendage closure (LAAC). OBJECTIVES: This study sought to assess the incidence, predictors, and clinical impact of persistent and recurrent DRT in LAAC recipients. METHODS: Data were obtained from an international multicenter registry including 237 patients diagnosed with DRT after LAAC. Of these, 214 patients with a subsequent imaging examination after the initial diagnosis of DRT were included. Unfavorable evolution of DRT was defined as either persisting or recurrent DRT. RESULTS: DRT resolved in 153 (71.5%) cases and persisted in 61 (28.5%) cases. Larger DRT size (OR per 1-mm increase: 1.08; 95% CI: 1.02-1.15; P = 0.009) and female (OR: 2.44; 95% CI: 1.12-5.26; P = 0.02) were independently associated with persistent DRT. After DRT resolution, 82 (53.6%) of 153 patients had repeated device imaging, with 14 (17.1%) cases diagnosed with recurrent DRT. Overall, 75 (35.0%) patients had unfavorable evolution of DRT, and the sole predictor was average thrombus size at initial diagnosis (OR per 1-mm increase: 1.09; 95% CI: 1.03-1.16; P = 0.003), with an optimal cutoff size of 7 mm (OR: 2.51; 95% CI: 1.39-4.52; P = 0.002). Unfavorable evolution of DRT was associated with a higher rate of thromboembolic events compared with resolved DRT (26.7% vs 15.1%; HR: 2.13; 95% CI: 1.15-3.94; P = 0.02). CONCLUSIONS: About one-third of DRT events had an unfavorable evolution (either persisting or recurring), with a larger initial thrombus size (particularly >7 mm) portending an increased risk. Unfavorable evolution of DRT was associated with a 2-fold higher risk of thromboembolic events compared with resolved DRT.

RESUMEN

AIM: Liver cirrhosis is the result of a vicious cycle of both chronic oxidative stress and inflammation. NADPH oxidase-4 (NOX4) and its companion, NOD-like receptor protein 3 (NLRP3) inflammasome, are emerging as therapeutic targets of liver fibrosis. MAIN METHODS: Baicalin (BA), a natural flavone, has been investigated for its therapeutic potential against cirrhosis induced by thioacetamide (TAA) (200 mg/kg, twice/week) for 12 weeks in Sprague-Dawley rats. Two doses of BA were administered (25 and 75 mg/kg/day, orally, a week after TAA was stopped and continued for 4 weeks). KEY FINDINGS: BA was able to reduce fibrosis visualized by Masson trichrome and immunohistochemical staining of the hepatic α-smooth muscle actin (α-SMA) and transforming growth factor-ß1. Moreover, BA was able to ameliorate inflammation by reducing hepatic NLRP3 inflammasome subunits, NLRP3 and caspase-1, both parts of the complex responsible for the activation of different interleukins (IL), measured as IL-1ß. In addition, BA was able to reduce hepatic nuclear factor kappa B (NF-κB)-driven inflammation through IL-6. BA targeted inflammation through its anti-oxidant ability evidenced by the enhancement of the hepatic superoxide dismutase (SOD) and reduced glutathione (GSH) activity and level, respectively, and the reduction of both hepatic malondialdehyde (MDA) and nitric oxide (NOx) contents. Treatment with BA significantly decreased TAA-induced elevation in hepatic NOX4, a key enzyme for reactive oxygen species (ROS) generation, as well as, inducible nitric oxide synthase (iNOS). SIGNIFICANCE: therefore, the study could conclude, the anti-fibrotic effect of BA through TGF- ß1/NOX4/NF-κB/NLRP3 pathway, exerting both anti-inflammatory and anti-oxidant effects.

RESUMEN

A new homoisoflavan, identified as (3 R)-7-hydroxy-3',4'-methylenedioxyhomoisoflavan, was isolated from Dracaena cinnabari Balf. f. resin. The structure was elucidated by one- and two-dimensional NMR spectroscopy as well as high resolution mass spectrometry. In addition, a diverse group of flavonoids were isolated, representing homoisoflavans, flavans, flavanones, chalcones and dihydrochalcones. The compounds were evaluated for their α-glucosidase and COX-II inhibition activity. The obtained IC50 values of the tested flavonoids gave an insight about some key structural features to their α-glucosidase and COX-II inhibitory activity. For α-glucosidase inhibitory activity, a flavanone skeleton was favorable over a flavan. For COX-II inhibition, the introduction of a fused heterocyclic ring at the homoisoflavan skeleton enhanced the activity.

RESUMEN

Imaging has long been taking its place in the diagnosis, monitor, and prognosis of rheumatic diseases. It plays a vital role in the appraisal of treatment. Key progress in the clinical practice of rheumatology is the innovation of advanced imaging modalities; such as musculoskeletal ultrasound (MSUS), computerized tomography (CT) and magnetic resonance imaging (MRI). These modalities introduced a promising noninvasive method for visualizing bone and soft tissues to enable an improved diagnosis. The use of MSUS in rheumatology is considered a landmark in the evolution of the specialty and its ease of use and many applications in rheumatic diseases make it a forerunner instrument in the practice. The use of MSUS among rheumatologists must parallel the development rate of the excellence revealed in the specialty. Moreover, innovative interventional imaging in rheumatology (III-R) is gaining fame and key roles in the near future for a comprehensive management of rheumatic diseases with precision. This review article throws light on the emergence of these robust innovations that may reshape the guidelines and practice in rheumatology, in particular, efforts to enhance best practice during the coronavirus disease 2019 (COVID-19) pandemic are endorsed.

RESUMEN

A 57-year-old postmenopausal woman presented with vague lower abdominal symptoms, dysuria and recurrent urinary tract infection of a year's duration. She had an intrauterine contraceptive device (IUCD) inserted 25 years previously and denied having any significant gynecological or urinary tract symptoms since the device was inserted. CT scan of her pelvis confirmed the presence of an IUCD that had migrated into the urinary bladder and on which a calculus had formed. An attempt at removal of the calculus and IUCD during cystoscopy failed. At cystolithotomy, the IUCD and the calculus were removed intact. IUCDs may produce complications several years after insertion.
