    Abstract Genomic screened homeobox 1 (Gsx1 or Gsh1) is a neurogenic transcription factor required for the generation of excitatory and inhibitory interneurons during spinal cord development. In the adult, lentivirus (LV) mediated Gsx1 expression promotes neural regeneration and functional locomotor recovery in a mouse model of lateral hemisection spinal cord injury (SCI). The LV delivery method is clinically unsafe due to insertional mutations to the host DNA. In addition, the most common clinical case of SCI is contusion/compression. In this study, we identify that adeno-associated virus serotype 6 (AAV6) preferentially infects neural stem/progenitor cells (NSPCs) in the injured spinal cord. Using a rat model of contusion SCI, we demonstrate that AAV6 mediated Gsx1 expression promotes neurogenesis, increases the number of neuroblasts/immature neurons, restores excitatory/inhibitory neuron balance and serotonergic neuronal activity through the lesion core, and promotes locomotor functional recovery. Our findings support that AAV6 preferentially targets NSPCs for gene delivery and confirmed Gsx1 efficacy in clinically relevant rat model of contusion SCI.

    Abstract Pain after lower limb orthopedic surgery can be severe. Poorly controlled pain is associated with adverse outcomes. Peripheral nerve blocks (PNB) have become popular in foot and ankle surgery for their effective pain control and low complication rates. It has always been assumed that hindfoot procedures are more painful than midfoot/forefoot procedures often requiring inpatient stay for pain relief. There are no published studies evaluating this assumption. To investigate whether hindfoot procedures are more painful than forefoot/midfoot procedures by measuring pain scores, assessing effectiveness of PNBs and patient satisfaction. One hundred forty patients undergoing elective foot and ankle surgery were prospectively studied. Inclusion criteria: Adults undergoing elective foot and ankle surgery. Exclusion criteria: Patients 16 years or under, those with alternate sources of pain, peripheral neuropathy, known substance abuse, psychiatric illness and incomplete pain scores. Pain was measured via the Visual Analog Scale at 3 time intervals: immediately, 6 hours and at 24 hours postoperatively. Analysis was via t-test. A p value of <.05 demonstrated a statistical significance. Forefoot/midfoot versus hindfoot surgery pain scores showed that there was no significant difference at any postoperative interval. PNB versus no PNB pain scores showed there was no significant difference, except at 24 hours postoperatively (p value .024). Patients who had a PNB experienced rebound pain at 24 hours. Hindfoot surgery is not more painful than forefoot/midfoot surgery. Patients who had a PNB experienced rebound pain at 24 hours postoperatively, a finding that requires further research.

    Abstract Purpose: Active surveillance is a safe and effective strategy for men with lower-risk prostate cancer who want to avoid local therapy; however, many patients on active surveillance progress to active treatment (eg, prostatectomy or radiation). We hypothesized that apalutamide would decrease active surveillance attrition rates through downstaging low-grade tumors.
    Materials and methods: This was an open-label, single-arm, phase II study testing 90 days of oral apalutamide 240 mg daily in men with low- to intermediate-risk prostate cancer on active surveillance. The primary objective was to determine the percentage of patients with a negative biopsy immediately following treatment. Secondary objectives were to assess long-term clinical outcomes, quality of life, safety, and biomarkers of response/resistance.
    Results: Twenty-three patients enrolled and 22 completed 90 days of apalutamide with post-treatment biopsy. Fifteen (65%) had Grade Group 1 disease, and all others had Grade Group 2 disease. Seven (30%) had favorable- to intermediate-risk disease. Of 22 evaluable patients, 13 (59%) had no residual cancer on post-treatment biopsy. The median time to first positive biopsy was 364 days (95% CI: 91-742 days). The impact of apalutamide on quality of life was minimal and transient. Decipher risk classifier revealed a greater number of negative post-treatment biopsies in those with higher baseline genomic risk score (
    Conclusions: The negative repeat biopsy rate following 90 days of apalutamide was high in men with prostate cancer followed on active surveillance. Apalutamide was safe, well tolerated, and had minimal impact on quality of life. Randomized studies evaluating the effects of apalutamide in men enrolled on active surveillance are warranted.

    Abstract Purpose: This study was conducted to review data gathered during a pilot project which trialed the use of a tablet computer, the iPad.
    Methods: Students from a segregated special education school and pre-vocational centre, with a wide range of intellectual and physical disabilities, were previously observed participating in 5-10-min introductory learning sessions with the iPad. This study reviewed quantitative and qualitative data collected during these sessions which included data regarding students' level of engagement and overall ability to learn how to operate the iPad and its applications.
    Results: Results were positive for level of engagement and ease of use with cause and effect applications. For lower functioning students or students not previously exposed to tablet technology, scores were lower but overall remained high based on the 5-point scaling used in this study.
    Conclusion: Regular use of tablet technology in the classroom with applications appropriate to the level of ability of the student has the potential to enhance engagement in learning as well as maximise independence in the classroom. Implications for Rehabilitation The iPad has the capacity to be used with learners of all different ability levels if applications are selected appropriately and learners are given equal opportunity to access this type of technology. Enjoyment when using the iPad was high overall and this type of technology has the potential to promote more engagement in the learning process. Many applications are easy to use and progress students through step by step increasing the potential for independent learning in the classroom.

    Abstract The study focused to evaluate and investigate optimized (using QbD) and novel ketoconazole (KTZ)-loaded solid lipid nanoparticles (KTZ-SLNs; 2% w/v KTZ) for enhanced permeation across skin. KTZ-SLNs were evaluated for size, distribution, zeta potential (ZP), percent entrapment efficiency (%EE), drug release, morphology (HRTEM and FESEM), thermal behaviour (DSC), spectroscopic (FTIR), and solid-state/diffraction characterization (X-ray diffraction, XRD). Moreover, ex vivo permeation and drug deposition into rat skin were conducted using Franz diffusion cell. The same was confirmed using human dermatome skin and fluorescence, confocal Raman, and vibrational ATR-FTIR microscopic methods. An in vivo dermatokinetics study was performed in rats to assess the extent of KTZ permeation into the skin. Stability including accelerated and photostability studies were conducted at different temperatures (2-8, 30, and 40 °C) for 12 months. The spherical, optimized KTZ-SLN formulation (KOF1) showed particle size of 293 nm and high EE of 88.5%. Results of FTIR, DSC, and XRD confirmed formation of KTZ-SLNs and their amorphous nature due to presence of KTZ in a dissolved state in the lipid matrix. In vitro release was slow and sustained whereas ex vivo permeation parameters were significantly high in KTZ-SLNs as compared to free drug suspension (KTZ-SUS) and marketed product (Nizral®; 2% KTZ w/v). Drug retention was 10- and five-fold higher than KTZ-SUS and marketed product, respectively. In vivo dermatokinetics parameters improved significantly with SLN formulation (410-900% enhanced). Confocal Raman spectroscopy experiment showed that KTZ-SLNs could penetrate beyond the human stratum corneum into viable epidermis. Fluorescent microscopy also indicated improved penetration of KTZ-SLNs. KTZ-SLNs were photostable and showed long-term stability over 12 months under set conditions.

    Abstract Foot osteoarticular tuberculosis is uncommon. Late diagnosis and sub-optimal management can lead to significant morbidity, deformity and even death. Preservation of life, limb and function can be achieved with prompt diagnosis and treatment. In 1882, Robert Koch published his discovery of mycobacterium tuberculosis as the causative agent of tuberculosis (TB), and showed the disease was infectious rather than inherited. Over two centuries later, TB remains one of the top 10 causes of death worldwide. Whilst in 90% of cases TB infects the respiratory system, in 10% it is extrapulmonary and can infect the skeletal, nervous, lymphatic and genitourinary systems. The spine is the most frequently affected site in the musculoskeletal system and this is known as Pott's disease. The foot and ankle is affected in only 0.13% cases of extrapulmonary TB. A high index of suspicion is thus required. This infrequency in incidence, heterogeneity of its presentation along with the difficulty in early diagnosis often causes significant delays in its treatment and hence results in a considerable disability. The medical treatment is well established but the role of surgery, its usefulness and its correct timing remain controversial. The main diagnostic issues include imaging being non-specific. Plain radiographs remain the first line imaging modality. MRI and CT scans provide greater detail and capture the disease at an earlier stage. Microbiological testing has low sensitivity and specificity becasue TB lesions are paucibacillary. Bone biopsy is of significant diagnostic value as it not only allows histological examination to detect granulomas but enables sensitivity and resistance testing of anti-tuberculous therapy (ATT). Issues relating to treatment include timing, duration, combination of chemotherapy and the challenge of multi drug resistant tuberculosis MDR-TB. The selection and timing of appropriate surgical techniques and optimal duration of follow-up are further points to consider. In this article we aim to review the literature on diagnosis and treatment of foot and ankle TB.

    Abstract Medical devices, being life-saving tools, are considered to be a boon for healthcare system. However, in addition to their therapeutic effects, there are several ill consequences that are caused by these devices. An effective cohort vigilant system was needed to manage such adverse effects. This had led to the introduction of materiovigilance. Materiovigilance is the study and follow-up of occurrences that arise as a result from the usage of the medical equipment. It not only manages adverse events (AE) but also creates harmonization among countries. Keeping these objectives in focus, the principles, perspectives, and practices with regard to materiovigilance that are followed in the USA, Europe, China, Japan, Australia, Canada, and India are being compared. Such a comparison is essential, which will help us to understand the gaps in the current regulatory systems in the above-mentioned countries and furthermore will provide a comprehensive picture to the regulatory authorities to amend any existing laws if required. These amendments may ensure optimal patient safety by providing them a benign experience from the use of medical devices.

    Abstract Research to understand the sources of stress and job satisfaction in pediatric oncology staff is limited. The aim of the authors' qualitative study was to describe the key work-related demands and rewards in relation to working closely with parents from the perspective of health care providers (HCPs). Semistructured interviews were conducted with 13 doctors, 9 nurses, 5 social workers, and 6 child life specialists. Line-by-line, focused, and theoretical coding was used to establish categories and themes. Constant comparisons were used to examine the relationships within and across codes and categories. Interviewing continued until no new themes emerged. HCPs found it rewarding when they established close or long-term relationships with parents and to helped families through the entire cancer journey, including palliative care. HCPs found it challenging to work with complex families; with parents who are demanding, rude, or angry; with parents who have differing views about the treatments and palliative care; and with having to relay bad news to parents. Future research could explore the relationship between the factors that the authors have identified and burnout syndrome.
