RESUMEN
OBJECTIVES: To assess and compare the immunogenicity of recombinant Insulin Aspart [manufactured by BioGenomics Limited (BGL-ASP)] with its originator NovoRapid® (manufactured by Novo Nordisk) in adult patients with type 2 diabetes mellitus. RESEARCH DESIGN AND METHODS: BGL-IA-CTP301 study was a randomized, open label, parallel group, multicenter phase-III clinical study to compare the efficacy and safety of recombinant Insulin Aspart 100 U/mL [manufactured by BioGenomics Limited (BGL-ASP)] with its reference medicinal product (RMP); NovoRapid® [manufactured by Novo Nordisk], in adult patients with Type 2 diabetes mellitus (T2DM). The primary objective of the study was to compare the immunogenicity of BGL-ASP and RMP; NovoRapid® in patient serum samples collected from phase-III clinical study. Immunogenicity was studied as the incidence of patients positive for anti-insulin Aspart (AIA) antibodies, developed against BGL-ASP/RMP at baseline, end of 12 week and end of 24 week of the treatment period. The changes in incidence of patients positive for AIA antibodies post-baseline were also studied to assess and compare the treatment-emergent antibody response (TEAR) between the treatment groups (BGL-ASP and RMP). Statistical evaluation was done by Fisher's exact test to compare the overall incidence of patients positive for AIA antibodies and the TEAR positives observed post-baseline in both the treated groups. An in-vitro neutralizing antibody assay (Nab assay) was also performed to study the effect of AIA antibodies in neutralizing the biological activity/metabolic function of the insulin. The neutralizing potential of AIA was studied by its effect on %glucose uptake. We also evaluated the association between AIA antibody levels and its impact on biological activity by studying the correlation between them. RESULTS: Analysis of immunogenicity data suggested that the percentage of patients positive for AIA antibodies until week 24 was similar and comparable in both the treatment groups, BGL-ASP and RMP; NovoRapid®. The changes in incidence of patients positive for AIA post-baseline in terms of TEAR positives were also similar and comparable between the treatment groups. The results of the Nab assay with confirmed positive AIA samples from BGL-ASP- and RMP-treated groups did not have any negative impact on %glucose uptake by the cells in Nab assay, confirming the absence of neutralizing antibodies in both the treatment groups. The correlation studies also showed absence of association between AIA antibody levels and percentage glucose uptake in both BGL-ASP and RMP-NovoRapid® treatment groups. CONCLUSIONS: The immunogenicity assessment based on the overall incidence of patients positive for AIA, changes in incidence of patients positive for AIA post-baseline, TEAR rates and absence of neutralizing antibodies, were found to be apparently similar and comparable in both the treatment groups (BGL-ASP and RMP). We conclude from our studies that the immunogenicity of BGL-ASP is similar and comparable to RMP and the observed immunogenicity in terms of anti-insulin Aspart antibody levels had no impact on the biological activity of insulin.

Familial Adult Myoclonus Epilepsy (FAME), with a prevalence of < 1/35 000, is known under different acronyms. The disease is transmitted in an autosomal dominant manner and is characterized by the occurrence of cortical myoclonic tremor, overt myoclonus, and rare bilateral tonic-clonic seizures. FAME is considered neurodegenerative, although it is relatively slow in progression. Diagnosis is based on specific neurophysiological testing, namely jerk-locked back-averaging, somatosensory evoked potentials, long latency reflex, and motor evoked potentials, among others. Imaging data, including functional magnetic resonance imaging, indicate a cortical origin of the cortical myoclonic tremor and decreased cerebellar activation. Cerebellar changes in Purkinje cells have been noted, from few neuropathology reports, in patients from isolated pedigrees. The differential diagnosis includes essential tremor, some forms of genetic generalized epilepsy, and progressive myoclonus epilepsies. Treatment is mainly symptomatic.

We have conceived, built, and operated a cryogenic vacuum valve with opening and closing times as short as 50 ms that can be used in strong magnetic fields and across a broad range of duty cycles. It is used to seal a cryogenic Penning trap at liquid-helium temperature for long-term storage of highly charged ions in a vacuum better than 10-15 hPa from a room-temperature ion beamline at vacuum conditions around 10-9 hPa. It will significantly improve any experiment where a volume at the most extreme vacuum conditions must be temporarily connected to a less demanding vacuum during repeated experimental cycles. We describe the design of this valve and show measurements that characterize its main features.
RESUMEN
The aluminium alloy (AA1100) was familiar with automotive flexible shaft coupling applications due to its high strength, good machinability, and superior thermal and resistance to corrosion characteristics. Machining tool life drives the prominent role for deciding the product quality (machining) act aims to productivity target with zero interruptions. The novelty of this present investigation is the focus on increasing tool life during the complexity of CNC turning operation for AA1100 alloy by using CBN coated insert tool with varied input parameters of spindle speed (SS), feed rate (f), and depth of cut (DOC). Design of experiment (L16), analysis of variance (ANOVA) statistical system adopted with response surface methodology (RSM) is implemented for experimental analysis. The turning input parameters of SS, f and DOC are considered as factors and its SS (900, 1100, 1300, and 1500 rpm), f (0.1, 0.15, 0.2, and 0.25), and DOC (0.1, 0.2, 0.3, and 0.4 mm) values are treated as levels. The investigational analysis was made with the ANOVA technique and the desirability of high tool life with input turning parameters was optimized by RSM, and sample no 11/16 was predicted as high tool life and performed with extended working hours compared to other samples. The RSM optimized best turning parameter combinations are 0.1 mm DOC, 0.2mm/rev to 0.25mm/rev f, and 1300 rpm-1500 rpm SS, facilitating a higher tool life of more than 20min.
RESUMEN
Natural fiber-reinforced polymer matrix composites are gathering significance in future trend applications such as automotive, aerospace, sport, and other engineering applications due to their superior enhanced mechanical, wear, and thermal properties. Compared to synthetic fiber, natural fiber is low adhesive and flexural strength properties. The research aims to synthesize the epoxy hybrid composites by utilizing the silane (pH = 4) treated Kenaf (KF) and sisal fiber (SF) as layering by uni, bi, and multi-unidirectional via hand layup techniques. Thirteen composite samples have been prepared by three-layer formation adopted with different weight ratios of E/KF/SF such as 100E/0KF/0SF, 70E/30KF/0SF, 70E/0KF/30SF, 70E/20KF/10SF, and 70E/10KF/20SF respectively. The effect of layer formation on the tensile, flexural, and impact strength of composites is studied by ASTM D638, D790, and D256 standards. The unidirectional fiber layer formed (sample 5) 70E/10KF/20SF composite is found maximum tensile and flexural strength of 57.9 ± 1.2 MPa and 78.65 ± 1.8 MPa. This composite is subjected to wear studies by pin-on-disc wear apparatus configured with a hardened grey cast-iron plate under an applied load of 10, 20, 30, and 40 N at different sliding velocities of 0.1, 0.3, 0.5, and 0.7 m/s. The wear rate of the sample progressively increases with increasing load and sliding speed of the composite. The minimum wear rate of 0.012 mg/min (sample 4) is found on 7.6 N frictional force at 0.1 m/s sliding speed. Moreover, sample 4 at a high velocity of 0.7 m/s with a low load (10 N) shows a wear rate of 0.034 mg/min. The wear-worn surface is examined and found adhesive and abrasive wear on a high frictional force of 18.54 N at 0.7 m/s. The enhanced mechanical and wear behavior of sample 5 is recommended for automotive seat frame applications.
RESUMEN
SETTING: The community-based primary palliative care programme in Kerala, India, has received international acclaim. Programme functioning is supported through Palliative Care Management Committees (PMCs) at the local government (LG) level. OBJECTIVE: To study the functioning of the PMCs within the decentralised governance space to identify achievements, gaps and notable innovations. DESIGN: This qualitative study included seven key informant interviews (KIIs), 28 in-depth interviews and a review of relevant publicly available policies and documents. Major themes were recognised from the KII transcripts. Codes emerging from the document review and in-depth interview transcripts were mapped into the identified thematic areas. RESULTS: Successful PMCs raised resources like money, human resource, equipment, had good skilled care options for symptom relief and facilitated reduced out-of-pocket expenditure by providing home care and free medicines, and improved access to interventions that addressed the social determinants of suffering like poverty. PMCs had varying managerial and technical capacities. In some LGs, the programme was weak and mostly limited to the supply of medicines, basic aids and appliances to patients' homes. CONCLUSION: Despite varied implementation patterns, PMCs in Kerala are examples of state-supported, community-owned care initiatives, that can potentially address medical and social determinants of suffering.
CONTEXTE: Le programme communautaire de soins palliatifs primaires du Kérala, Inde, a été applaudi sur la scène internationale. Le fonctionnement du programme est soutenu par des Comités de gestion des soins palliatifs (PMC) au niveau des gouvernements locaux (LG). OBJECTIF: Évaluer le fonctionnement des PMC au sein de l'espace de gouvernance décentralisée, afin d'identifier les réussites, les lacunes et les principales innovations. MÉTHODES: Dans le cadre de cette étude qualitative, sept entretiens avec des informateurs clés (KIIs), 28 entretiens approfondis et une analyse des politiques et documents accessibles au public ont été réalisés. Les transcriptions des KII ont permis de faire émerger les thèmes principaux. Les codes émergeant de l'analyse documentaire et des transcriptions des entretiens approfondis ont été associés aux domaines thématiques identifiés. RÉSULTATS: Les PMC les plus performants ont pu mobiliser des ressources, telles que de l'argent, des ressources humaines ou des équipements. Ils proposaient également des options de soins de qualité pour soulager les symptômes, facilitaient la réduction des frais à la charge du patient en fournissant des soins à domicile et des médicaments gratuits, et ont permis d'améliorer l'accès aux interventions qui s'attaquaient aux déterminants sociaux de la souffrance, tels que la pauvreté. Les capacités techniques et de gestion variaient d'un PMC à l'autre. Le programme de certains LG était faible, principalement limité à la fourniture de médicaments et d'aides et de matériels de base pour le domicile des patients. CONCLUSION: Malgré des schémas de mise en Åuvre variés, les PMC du Kérala sont des exemples d'initiatives communautaires de santé soutenues par l'état qui peuvent potentiellement s'attaquer aux déterminants sociaux et médicaux de la souffrance.
RESUMEN
INTRODUCTION: In the backdrop of the Sustainable Development Goals (SDGs), the state of Kerala, India, revamped its existing primary health centres (PHCs) into people-friendly family health centres (FHCs) in order to provide comprehensive primary care as part of a mission-based ('Aardram') initiative. It was envisioned that the mission's implementation and operation would make use of decentralised governance. The present study explored how the decentralised governance influenced reorganisation of primary care. METHODS: The study adopted an exploratory approach using qualitative methods: key informant interviews (n = 8), in-depth interviews (n = 20) and document reviews. Thematic analysis was done following deductive coding and the themes that emerged were organised under a schema. RESULTS: The results could be summarised under five overarching themes. Strong political commitment, combined with bureaucratic competence, facilitated implementation and functioning of 'Aardram' primary care. The insights developed through multi-sectoral training helped local governments (LGs) get involve and engage with the health system as a team in order to plan and implement interventions. The decentralised governance structures enabled re-engineering of PHCs by mobilisation of financial resources, provision of human resources, infrastructure modification, and enhanced community participation at various levels. Non-uniformity of commitment, sub-optimal engagement of urban LGs and issues of sustainability and monitoring were the shortcomings observed. CONCLUSION: Decentralised governance played a positive role in the re-engineering of PHCs, which was utilised as a platform to demonstrate best practices in health governance through a participatory approach. The importance of empowering LGs through capacity building to address challenges in achieving primary care SDGs is highlighted in this study.
INTRODUCTION: Dans le contexte des Objectifs de développement durable (SDG), l'État du Kérala, Inde, a transformé ses centres de soins primaires (PHC) existants en centres de santé familiale (FHC) conviviaux afin de fournir des soins primaires complets dans le cadre d'une initiative mandatée en mission ('Aardram'). Il était prévu que la mise en Åuvre et le fonctionnement de cette mission fassent appel à la gouvernance décentralisée. Cette étude a examiné l'influence de la gouvernance décentralisée sur la réorganisation des soins primaires. MÉTHODES: L'étude a eu recours à une approche exploratoire, en utilisant des méthodes qualitatives : entretiens avec des informateurs clés (n=8), entretiens approfondis (n=20) et analyses documentaires. Une analyse thématique a été réalisée selon un codage déductif et les thèmes identifiés ont été structurés sous forme de schéma. RÉSULTATS: Les résultats peuvent être résumés en cinq thèmes principaux. Un engagement politique fort, associé à des compétences bureaucratiques, ont facilité la mise en Åuvre et le fonctionnement des soins primaires de la mission 'Aardram'. Les connaissances acquises grâce à la formation multisectorielle ont aidé les gouvernements locaux (LG) à s'impliquer et à s'engager dans le système de santé en tant qu'équipe afin de planifier et de mettre en place des interventions. Les structures de gouvernance décentralisées ont permis de réorganiser les PHC en mobilisant des ressources financières, en fournissant des ressources humaines, en modifiant les infrastructures et en renforçant la participation communautaire à différents niveaux. Parmi les lacunes observées figurent le manque d'uniformité de l'engagement, l'engagement sous-optimal des LG urbains et les questions de durabilité et de suivi. CONCLUSION: La gouvernance décentralisée a joué un rôle positif dans la réorganisation des PHC, qui a été utilisée comme une plateforme pour illustrer les bonnes pratiques en matière de gouvernance sanitaire par le biais d'une approche participative. Cette étude met en évidence l'importance de l'autonomisation des LG au travers du renforcement des capacités afin de relever les défis liés à la réalisation des SDG en matière de soins primaires.
RESUMEN
OBJECTIVES: To study the risk factors of first episode simple febrile seizures in children. METHODS: This case control study was conducted at the pediatric department of our tertiary care hospital. Cases were children of age group 6 months to 5 years presenting with first simple febrile seizures (n=214), and Controls were children of same age group presenting with short febrile illness but without any seizures (n=214). Blood investigations were done to diagnose iron deficiency, which was diagnosed by adopting cut off of hemoglobin value <11 g/dL, serum ferritin < 12 ng/mL and red cell distribution width >15%. Other risk factors studied included age, gender, socioeconomic status, prematurity, family history of febrile seizure and epilepsy in first degree relatives, consanguinity, neonatal hospital admissions, day care attendance (for >1 mo), under nutrition, and immunization status of the child. Univariate analysis for crude odds ratio and multivariate analysis (logistic regression) was performed to study the adjusted odds ratio and independent risk factors. RESULTS: The significant risk factors for first episode simple febrile seizure were iron deficiency [OR (95% CI) 5.78 (3.56-9.38); P=0.001], family history of febrile seizure [OR 4.31 (2.37- 7.83), P<0.001] or epilepsy [OR 4.25(2.21-8.19), P<0.001] in first degree relatives, day care attendance for >1 month [OR 4.81 (2.41-9.59), P<0.001], and prematurity at birth [OR 5.18 (2.48-10.84), P<0.001]. CONCLUSION: Iron deficiency, family history of febrile seizure and epilepsy in first degree relatives, day care attendance and premature birth are the risk factors for first episode simple febrile seizures in children.

Outcomes of early cancers after kidney transplantation are not well-understood. We included recipients of first live and deceased donor kidney transplants who developed de novo cancers in Australia and New Zealand between 1980-2016. We compared the frequency and stage of specific cancer types that developed early (≤12-months) and late (>12-months) post-transplantation. Risk factors for death were evaluated using multivariable Cox regression analyses. Of 2,759 recipients who developed de novo cancer, followed-up for 40,035 person-years, 243 (8.8%) patients were diagnosed with early cancer. Post-transplant lymphoproliferative disease, urinary cancers and melanoma were the most common cancer types (26%, 18%, and 12%) and the majority were either in-situ or locally invasive lesions (55%, 84%, and 86%). Tumors arising early from the gastrointestinal and respiratory systems were uncommon but aggressive, with 40% presenting with metastatic disease at time of diagnosis. Overall, 32% of patients with early cancers died within a median of 4.7 months (IQR:0.6-16) post-diagnosis and 91% were cancer-related deaths. Older recipient and donor age were associated with an increased risk of all-cause death. Early cancers, though infrequent in kidney transplant recipients, are associated with poor outcomes, as nearly 1 in 3 died from cancer-related death; with majority of deaths occurring within 12-months of cancer diagnosis.

In this concept review, the fundamental and polymerization chemistry of inverse vulcanization for the preparation of statistical and segmented sulfur copolymers, which have been actively developed and advanced in various applications over the past decade is discussed. This concept review delves into a discussion of step-growth polymerization constructs to describe the inverse vulcanization process and discuss prepolymer approaches for the synthesis of segmented sulfur polyurethanes. Furthermore, this concept review discusses the advantages of inverse vulcanization in conjunction with dynamic covalent polymerization and post-polymerization modifications to prepare segmented block copolymers with enhanced thermomechanical and flame retardant properties of these materials.
RESUMEN
Pancreas transplantation (PT) allows improved glycaemic control for patients with complicated type 1 diabetes mellitus and is most commonly performed simultaneously with a renal transplant. Imaging modalities are critical for the assessment of pancreatic graft dysfunction, as clinical assessment and hyperglycaemia lack robust sensitivity for the transplant clinician. Biopsy represents the most conclusive standard of PT graft assessment but is challenging due to its invasive nature and the potential morbidity associated with the procedure. Innovative imaging technologies offer the opportunity to apply these modalities to improve PT outcomes while using non-invasive technologies to provide a diagnostic sensitivity that traditionally only biopsies can provide. Early graft dysfunction has traditionally been investigated with Computed tomography (CT) and ultrasound (US) scans. We explore adjuncts to these modalities including the application of contrast enhanced ultrasound (CEUS) for routine post-operative graft assessment to inform post-operative treatment strategies. There is currently a dearth of imaging modalities to reliably monitor long term graft function, but the use of innovative functional imaging techniques and how they can be applied to PT is discussed. Perfusion CT and glucose stimulated magnetic resonance imaging (MRI) to detect whole organ function are examined. In addition, early phase developments in beta-cell specific imaging methods to quantify beta-cell mass longitudinally are described. The clinical applications of such tools including Mn2+-enhanced MR and GLP-1R targeted PET/CT are reviewed and may demonstrate opportunities to provide the transplant clinician with greater information to support improved patient care.

Insufficient sleep is a major health issue. Inadequate sleep is associated with an array of poor health outcomes, including cardiovascular disease, diabetes, obesity, certain forms of cancer, Alzheimer's disease, depression, anxiety, and suicidality. Given concerns with typical sedative hypnotic drugs for treating sleep difficulties, there is a compelling need for alternative interventions. Here, we report results of a non-invasive electrical brain stimulation approach to optimizing sleep involving transcranial alternating current stimulation (tACS). A total of 25 participants (mean age: 46.3, S.D. ± 12.4, 15 females) were recruited for a null-stimulation controlled (Control condition), within subjects, randomized crossed design, that included two variants of an active condition involving 15 min pre-sleep tACS stimulation. To evaluate the impact on sleep quality, the two active tACS stimulation conditions were designed to modulate sleep-dependent neural activity in the theta/alpha frequency bands, with both stimulation types applied to all subjects in separate sessions. The first tACS condition used a fixed stimulation pattern across all participants, a pattern composed of stimulation at 5 and 10 Hz. The second tACS condition used a personalized stimulation approach with the stimulation frequencies determined by each individual's peak EEG frequencies in the 4-6 Hz and 9-11 Hz bands. Personalized tACS stimulation increased sleep quantity (duration) by 22 min compared to a Control condition (p = 0.04), and 19 min compared to Fixed tACS stimulation (p = 0.03). Fixed stimulation did not significantly increase sleep duration compared to Control (mean: 3 min; p = 0.75). For sleep onset, the Personalized tACS stimulation resulted in reducing the onset by 28% compared to the Fixed tACS stimulation (6 min faster, p = 0.02). For a Poor Sleep sub-group (n = 13) categorized with Clinical Insomnia and a high insomnia severity, Personalized tACS stimulation improved sleep duration by 33 min compared to Fixed stimulation (p = 0.02), and 30 min compared to Control condition (p < 0.1). Together, these results suggest that Personalized stimulation improves sleep quantity and time taken to fall asleep relative to Control and Fixed stimulation providing motivation for larger-scale trials for Personalized tACS as a sleep therapeutic, including for those with insomnia.
RESUMEN
STUDY OBJECTIVE: Due to the rarity of the Andersson lesion (AL), the literature is ambiguous regarding the type of surgical fixation, need for debridement and deformity correction. The purpose of this retrospective study is to evaluate the efficacy, feasibility and functional outcome of posterior fixation in AL. MATERIALS AND METHODS: This study included 35 patients having thoracolumbar AL operated for in situ fixation and fusion with minimum of 24-month follow-up. VAS (Visual Analogue Score) back pain, ODI (Oswestry Disability Index), Frankel's grade were compared and analyzed. Union status was noted with complications. RESULTS: The mean age of 35 patients was 56.34(± 11.3) years with average follow-up of 51.49 months. Two patients had AL at two levels. 27/37 AL were at discal level. Average estimated blood loss (EBL) was 276.43 ml and duration of surgery was 130.43 min. On an average, operated segments needed 7.77 screws. There were ten minor complications without long-term sequel. Neurological improvement was noted in 30 patients. Average preoperative VAS score improved from 8.69 to 3.14, ODI score improved from 68.76 to 18.77 at final follow-up which were significant (p < 0.05). There was significant improvement in Frankel's grading (Z = - 4.354, P = 0.00). CONCLUSIONS: Surgical management of AL by posterior approach and posterior stabilization can give satisfactory results without the need of extensive anterior reconstruction, bone grafting or deformity correction procedures without added morbidity and complications.

INTRODUCTION: To investigate the efficacy of Ultrasonic Bone Scalpel (UBS) in thoracic spinal stenosis (TSS) in comparison to traditional technique. MATERIAL AND METHODS: A total of 55 patients who had undergone conventional surgery (Group A) are compared with 45 patients of UBS (Group B) in TSS. The primary outcome measure of Modified Japanese Orthopaedic Association score (m JOA) with neurological complications and dural injury were assessed. Secondary outcome measures of total blood loss (TBL), time duration of surgery (ORT) and length of hospital stay (LHS) were analysed. RESULTS: The pre-operative mJOA score 5.00(4.00-6.00) in the group A and 5.00(4.00-6.00) in the group B improved to 7.00(7.00-8.00) in the group A and 9.00(9.00-10.00) in the group B, respectively (P<0.001) at final average follow-up of 117.55 months for group A and 75.69 months in group B. More significant grade of myelopathy improvement and mJOA recovery rate (RR) were noted in group B. The TBL, ORT and LHS were more favourable in group B as compared to group A (p<0.0001). The group A had 9 (16.36%) neurological deficits compared to 2 (4.44%) in group B (p<0.001). Dural tears occurred in both groups (A=11, B=9). It was more frequent and not repairable in group A but without significant statistical difference. CONCLUSION: UBS can reduce neurological deficits and improve outcomes in TSS. Secondarily, reduced blood loss, lesser surgical time and reduced LHS are significant added advantages of this new technology.
RESUMEN
INTRODUCTION: Various in vitro and in vivo animal studies have shown that adenosine triphosphate (ATP) has a stimulatory role and nitric oxide (NO) has an inhibitory role in modulating bladder contractility. However, it is not known what happens to the urinary levels of ATP and NO in humans with underactive bladder (UAB). METHODS: In this prospective case-control study, we compared ATP and NO levels in twenty six male patients of UAB with a bladder contractility index (BCI) of < 100 and 18 healthy male volunteers without any lower urinary tract symptoms (LUTS). RESULTS: The mean urinary ATP levels were significantly lower in cases compared to controls (546.1 ± 37.3 pg/µl vs. 610.7 ± 24.9 pg/µl, p value < 0.001) and the mean NO levels were significantly higher in cases compared to controls (1233.4 ± 91.2 pg/µl vs. 1126.3 ± 91.3.4 pg/µl, p value < 0.001). The mean NO/ATP ratio in cases was significantly higher than that of controls (2.26 ± 0.2 vs. 1.84 ± 0.18, p value < 0.000). Using receiver operating curve (ROC) analysis, we noted the area under the curve (AUC) for NO/ATP ratio to be 0.91 in the diagnosis of cases. A cut-off value of 2.06 for NO/ATP ratio had sensitivity, specificity and diagnostic accuracy of 88.5%, 88.9% and 88.6%, respectively, in diagnosing patients with UAB. CONCLUSION: Patients with UAB have significantly higher levels of urinary NO and decreased levels of urinary ATP. Urinary NO/ATP levels can be considered as a noninvasive alternate test for diagnosing bladder underactivity.

AIMS: The presence of foodborne pathogens in preharvest agricultural water has been identified as a potential contamination source in outbreak investigations, driving markets and auditing bodies to begin requiring water treatment for high-risk produce. Therefore, it is essential that we identify water treatment methods which are effective as well as practical in their application on farm. METHODS AND RESULTS: In this work, we evaluated two sanitizers which are most prominent in preharvest agricultural water treatment (calcium hypochlorite (free chlorine: 3-5 ppm) and peracetic acid (PAA: 5 ppm)), an EPA registered antimicrobial device (ultraviolet light (UV)), in addition to a combination approach (chlorine + UV, PAA + UV). Treatments were evaluated for their ability to inactivate total coliforms and generic Escherichia coli and consistency in treatment efficacy over 1 h of operation. Physicochemical variables were measured along with microbial populations at 0, 5, 15, 30, 45 and 60 min of operation. Escherichia coli and coliform counts showed a significant (P < 0·05) reduction after treatment, with combination and singular treatments equally effective at inactivating E. coli and coliforms. A significant increase (P < 0·05) in oxidation-reduction potential was seen during water treatment (Chlorine; UV + Chlorine), and a significant reduction (P < 0·05) in pH was seen after PAA and PAA + UV treatments (60 min). CONCLUSION: Overall, the results indicate that all treatments evaluated are equally efficacious for inactivating E. coli and coliforms present in surface agricultural water. SIGNIFICANCE AND IMPACT OF THE STUDY: This information when paired with challenge studies targeting foodborne pathogens of interest can be used to support grower decisions when selecting and validating a preharvest agricultural water treatment programme.

INTRODUCTION: To analyse the results of Cauda Equina Syndrome (CES) operated by Percutaneous Transforaminal Endoscopic Lumbar Discectomy (PTELD). MATERIAL AND METHODS: The study is a retrospective series of 15 patients operated by PTELD. Bladder dysfunction was classified as incomplete CES (CESI) and complete CES retention (CESR). Bladder / motor recovery rate and its timing, Oswestry Disability Index (ODI), Visual Analogue Score (VAS), patient satisfaction index, and sexual dysfunction were used to measure the outcome objectively. Additionally, in CESR patients, post-void residual (PVR) urine was measured by sonography. Complications and technical problems were noted. RESULTS: There were ten patients of CESI and five patients of CESR. The average follow-up was 20.33(12.05) months. Bladder symptoms recovery was 100%, and motor recovery was 80%. VAS for back pain recovered to 0.53(0.52) from 8(2.39). VAS for leg pain recovered to 0.13(0.35) from 9.20(1.32). ODI improved to 6.07(2.85) from 77.52(13.20). The time to the recovery of bladder function was 1.47(1.55) days. All CESR patient's abnormal PVR urine was normalised at five weeks post-operative. No complications were reported. However, five technical executional problems occurred. CONCLUSION: PTELD can be considered for CES treatment due to its substantial and quick recovery advantages. However, more evidence support is needed to make it a practice recommendation.
RESUMEN
