Abstract
PURPOSE The study compared the efficacy of commencing supervised exercise in men with prostate cancer before and after prostatectomy on objective and patient-reported outcomes, hospital length of stay, and urinary incontinence. METHODS Forty-one men were randomised to a 6-week prehabilitation or rehabilitation exercise programme. Prehabilitation involved resistance and aerobic exercise thrice weekly pre-surgery, while rehabilitation comprised the same commencing 6-weeks post-surgery. Assessments included strength, function (chair rise, stair climb, 400-m, 6-m usual, fast, and backwards walk), body composition, fatigue and quality of life, undertaken at pre-surgery, early post-surgery and late post-surgery phase, with urinary incontinence (24-h pad test) assessed at 2, 6, and 12-weeks post-surgery. Intention-to-treat and sensitivity analyses were undertaken. RESULTS Of thirty-eight men (48-73 years), 29 completed all assessments with most undergoing robotic-assisted laparoscopic prostatectomy (92.1%). In the pre-surgery phase, prehabilitation improved muscle strength (leg press: 17.2 kg; chest press: 2.9 kg; p ≤ 0.001), 400-m, chair rise, 6-m fast and backward walk tests (p ≤ 0.001-0.028). Strength and function declines in the early post-surgery phase were maintained late post-surgery. Rehabilitation showed declines of these outcomes after surgery with improvement late post-surgery (leg press: 14.6 kg, p < 0.001; chest press: 6.8 kg, p < 0.001; 400-m walk: -12.0 s, p = 0.005), resulting in no difference between groups at 12 weeks. There were no significant differences between groups for patient-reported outcomes, hospital length of stay or urinary incontinence. CONCLUSION Pre-surgical exercise enhanced strength and function, protecting against post-surgery declines. Although exercise post-surgery is beneficial for recouping strength and function, where possible men undergoing prostatectomy are encouraged to exercise pre-surgery.

Abstract
BACKGROUND Obesity has been recognized as a risk factor in the development and recurrence of breast cancer and is also associated with poor prognostic outcomes. This systematic review and network meta-analysis aimed to identify the most effective exercise, physical activity, and dietary interventions to reduce fat mass, body fat percentage and body weight as well as potentially increase lean mass in women diagnosed with or at high risk of breast cancer. METHODS A systematic search of databases was performed up to May 2022. Eligible randomized controlled trials examined the effects of exercise, physical activity and/or dietary interventions on fat mass and lean mass in women diagnosed with or at high risk of breast cancer. A random-effects network meta-analysis was conducted to determine the effects of different interventions across outcomes when sufficient studies were available. RESULTS Eighty-four studies (n = 6428) were included in this review. Caloric restriction and combined exercise + caloric restriction significantly reduced fat mass (range, -3.9 to -3.7 kg) and body weight (range, -5.3 to -4.7 kg), whereas physical activity + caloric restriction significantly reduced body fat percentage (-2.4%; 95% confidence interval [CI], -3.4% to -13%) and body mass index (-2.2 kg × m-2 ; 95% CI, -3.0 to -1.4 kg × m-2 ) in breast cancer patients. Resistance exercise was the most effective intervention to increase lean mass (0.7 kg; 95% CI, 0.5-1.0 kg) in breast cancer patients. CONCLUSION Multimodal exercise and diet programs were the most effective interventions to reduce fat mass, body fat percentage, and body weight and increase and/or preserve lean mass.

Abstract
PURPOSE This study aimed to examine the feasibility and potential efficacy of presurgical exercise in patients with bladder cancer scheduled for open radical cystectomy with follow-up postsurgery. METHODS Prospective single-group design with assessments at baseline, presurgery, and 3 months postsurgery was used in this study. Multimodal supervised resistance and aerobic exercise was undertaken 2-3 d·wk -1 at moderate intensity for a median of 3.5 wk (interquartile range [IQR] = 1.3-5.6). Feasibility was assessed by recruitment and completion rates, patient safety, program tolerance, adherence, and compliance. Lean and fat mass were assessed by dual-energy x-ray absorptiometry, physical function by a battery of tests (chest press and leg press strength, 6-min walk test [6MWT], timed up-and-go, repeated chair rise), and quality of life (QoL), psychological distress, and body image by questionnaire. Hospital length of stay (LOS) and complications were assessed by medical records. RESULTS Thirty-seven patients were referred with 20 recruited (67.3 ± 12.2 yr) and a presurgery intervention completion rate of 80% (16 of 20). The individual median program adherence was 100.0% (IQR = 89.4-100.0) with compliance of 100.0% (IQR = 90.5-100.0) for resistance exercise and 81.8% (IQR = 55.0-99.5) for aerobic exercise. There were no exercise-related adverse events. Body composition did not change presurgery; however, there were improvements ( P < 0.05) in leg press strength (16%), 6MWT distance (8%), timed up-and-go (12%), chair rise (10%), and multiple QoL domains including mental health. Median LOS was 8.0 d (IQR = 7.0, 15.0). Postsurgery, there were declines in components of QoL and apparent body image dissatisfaction. CONCLUSIONS A preradical cystectomy exercise program is feasible, safe, and well tolerated with improvements in physical function and QoL. Supervised multimodal exercise in bladder cancer patients before cystectomy can enhance physical and mental health potentially buffering the effects of surgery.

Abstract
PURPOSE To determine the feasibility, safety and preliminary efficacy of a telehealth supervised exercise programme in patients with advanced melanoma receiving checkpoint inhibitor therapy. METHODS A 8-week non-randomised feasibility pilot trial utilising a telehealth delivered multimodal exercise programme undertaken thrice weekly with assessments at baseline and post-intervention. The study was considered feasible if there were no severe or life-threatening adverse events as a result of exercise, and three or more of the following criteria were met: the recruitment rate was >50%, completion rate was >80%, median programme attendance was >75%, median exercise compliance >75%, and average tolerance was >70%. Preliminary efficacy was assessed for objective measures of physical function (2-min step test, repeated chair stand test, 30-s push-up test, and a modified static balance test) and quality of life (QoL), fatigue and other patient-reported outcomes were assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30. RESULTS Eleven patients (32-80 years) were included in the study (6 female, 5 male). The recruitment rate was 48%, completion rate 91%, programme attendance 88%, median exercise compliance 82.1% and 84.9% for resistance and aerobic exercise, respectively, and tolerance 88%, with no severe or life-threatening adverse events as a result of exercise. In terms of preliminary efficacy, physical function significantly improved while QoL was maintained following the intervention. CONCLUSION An 8-week telehealth exercise intervention is feasible and safe for patients with advanced melanoma and appears to improve physical function while preserving QoL during checkpoint inhibitor therapy.

Abstract
To investigate the association between skeletal muscle mass and adiposity measures with disease-free progression (DFS) and overall survival (OS) in patients with advanced lung cancer receiving immunotherapy, we retrospectively analysed 97 patients (age: 67.5 ± 10.2 years) with lung cancer who were treated with immunotherapy between March 2014 and June 2019. From computed tomography scans, we assessed the radiological measures of skeletal muscle mass, and intramuscular, subcutaneous and visceral adipose tissue at the third lumbar vertebra. Patients were divided into two groups based on specific or median values at baseline and changes throughout treatment. A total number of 96 patients (99.0%) had disease progression (median of 11.3 months) and died (median of 15.4 months) during follow-up. Increases of 10% in intramuscular adipose tissue were significantly associated with DFS (HR: 0.60, 95% CI: 0.38 to 0.95) and OS (HR: 0.60, 95% CI: 0.37 to 0.95), while increases of 10% in subcutaneous adipose tissue were associated with DFS (HR: 0.59, 95% CI: 0.36 to 0.95). These results indicate that, although muscle mass and visceral adipose tissue were not associated with DFS or OS, changes in intramuscular and subcutaneous adipose tissue can predict immunotherapy clinical outcomes in patients with advanced lung cancer.

Abstract
INTRODUCTION Evidence regarding the role of exercise in pancreatic cancer (PanCa) is limited and is derived exclusively under tightly controlled research conditions. This study aimed to quantify adherence, adverse events, and changes in physical and psychological outcomes in any patients with PanCa referred to undertake exercise during nonsurgical treatment. METHODS The study involved 22 patients with localized or metastatic PanCa undertaking a clinic-based exercise program during chemotherapy or chemoradiotherapy. The program included supervised aerobic and resistance exercise undertaken twice weekly for 12 wk and a 12-wk follow-up with supervised exercise optional dependent on patient preference and condition. Patients were monitored for adherence and adverse events. Objective and patient-reported outcomes were assessed at baseline, 12 wk, and 24 wk. RESULTS A total of 251 sessions were attended by 19 patients over the first 12 wk (attendance rate, 55%). Complete case analyses indicated significant ( P < 0.05) improvements in functional ability (5.2%-17.2%), muscle strength (16.9%-25.1%), and static balance (6.8%). There were no significant changes in body composition or patient-reported outcomes except for sleep quality, which deteriorated; however, at an individual level, several patients had clinically relevant improvements in cancer-related fatigue and quality of life. Patients who continued with supervised exercise to week 24 largely preserved improvements in functional ability, muscle strength, and static balance. No serious adverse events resulted from the exercise program. CONCLUSIONS Individualized, supervised aerobic and resistance exercise in a clinic-based setting appears to be safe and may improve or maintain physical and psychological health in patients with PanCa undergoing nonsurgical treatment.

Abstract
Breast cancer is the most prevalent cancer in women worldwide and is the most common cancer diagnosis made during pregnancy or in the postpartum period. When breast cancer is diagnosed either during pregnancy or in the first-year postpartum, it is referred to as pregnancy-associated breast cancer. The aim of this review is to assess existing literature regarding the recommendations and outcomes of participating in exercise for people with pregnancy-associated breast cancer. The occurrence of pregnancy-associated breast cancer is increasing as a growing number of women delay first pregnancies. Women undergoing treatment for pregnancy-associated breast cancer are dealing with both cancer and its treatment as well as a pregnancy or postpartum period, and often encounter symptoms associated with cancer diagnosis and treatment, such as nausea, pain and fatigue while simultaneously navigating a pregnancy or early motherhood. These experiences can be barriers to participating in exercise, despite exercise being associated with numerous benefits for both pregnancy health and breast cancer outcomes. Numerous studies report the benefits of exercising during breast cancer treatment in ameliorating associated symptoms, and some studies report that engaging in exercise can lead to healthier and lower risk pregnancies. However, there is a lack of consensus around appropriate exercise programmes for this specific population. Given the associated benefits of participating in exercise for both breast cancer patients and pregnant/postpartum women as separate groups, research into exercise medicine designed specifically for the pregnancy-associated breast cancer population is needed.

Abstract
PURPOSE To perform a systematic review and network meta-analysis to investigate the most effective intervention for improving body composition outcomes in prostate cancer patients during or after treatment. METHODS A systematic search was undertaken in multiple databases from inception to December 2020. Randomized clinical trials examining the effects of exercise/physical activity and/or nutrition interventions on body composition and body weight measures in prostate cancer patients were included. The primary endpoints were both whole-body and regional fat mass and lean mass measures, with body weight and BMI as secondary outcomes. A frequentist random-effects network meta-analysis was undertaken to examine the clustering effect of intervention modalities or control groups on the outcomes of interest. The study protocol is publicly available on PROSPERO (CRD42020202339). RESULTS Fifty articles describing 47 trials (n = 3207) were included. Resistance training and combined resistance and aerobic exercise were the most effective interventions to reduce body fat percentage (-0.9%; 95% confidence interval [CI], -1.4% to -0.3%) and fat mass (-0.5 kg; 95% CI, -0.9 to -0.1 kg), respectively. For whole-body and regional lean mass, combined resistance and aerobic exercise + healthy diet (0.6 kg; 95% CI, 0.1 to 1.0 kg) and resistance training alone (0.7 kg, 95% CI: 0.4 to 1.0 kg) were the best intervention, respectively. A low-fat diet was the most effective for reducing body weight immediately after or at follow-up, while no intervention promoted significant reductions in BMI. CONCLUSIONS These results indicate that a resistance-based exercise program alone or combined with a general healthy diet are the most effective interventions for improving overall body composition in men with prostate cancer.

Abstract
Background The benefits of resistance training for patients with type 2 diabetes (T2D) are well documented; however, the effects of exercise with different muscle contraction types such as eccentric versus concentric contractions on physiological outcomes for this population are not clear. This study compared eccentric-only (ECC) and concentric-only resistance training (CON) to test the hypothesis that ECC would be superior to CON to improve insulin sensitivity, lipid profile, body composition, muscle strength and physical function of patients with T2D. Methods Adults with T2D (50–79 years) were allocated to the ECC (n = 9) or CON group (n = 9). Resistance exercises (chest press, lateral pulldown, bicep curl, triceps extension, leg extension, leg curl, calf raise, abdominal crunch) consisting of 2–3 sets of 10 eccentric-only (5 s) or concentric-only contractions (1–2 s) was performed twice a week for 12 weeks. Changes in blood biomarkers, body composition, muscle strength and physical function from pre- to post-intervention were compared between groups. Results Overall rating of perceived exertion (RPE, 1–10 Borg scale) was lower (p < 0.05) for ECC (2.9 ± 1.2) than CON (5.4 ± 1.1). No significant changes in blood biomarkers were found for both groups. Lean mass increased [effect size (ES) = 0.148, ECC 3.2 ± 6.9%; CON 3.6 ± 2.3%], and fat mass decreased (ES = 0.545, ECC − 6.1 ± 12.4%; CON − 7.1 ± 16.4%) (p < 0.05) similarly. One-repetition maximal strength of each exercise increased (p < 0.05) for both ECC (12–37%) and CON (27–68%). Both groups improved (p < 0.05) 6-min walk distance (ES = 0.083, ECC 12.2 ± 2.3%; CON 12.5 ± 15.3%) and chair rise time (ES = 0.463, ECC − 13.4 ± 25.4%; CON − 20.0 ± 53.3%) but only ECC improved (p < 0.05) the timed up-and-go test (− 11.3 ± 13.6%, ES 0.014). No significant changes in balance tests were found for both groups. Conclusion These results did not fully support the hypothesis but showed that ECC was as effective as CON to improve body composition, muscle strength, and physical function with lesser RPE. Future studies should investigate whether larger differences between ECC and CON are evident when increasing the exercise frequency and matching the intensities of the two-exercise protocols.

Abstract
Purpose: Although exercise medicine is recommended to counter treatment-related
side-effects and improve health-related outcomes of patients affected by
different cancers, no specific recommendations exist for patients with
melanoma. As a result, we systematically examined the current evidence
regarding the effects of physical activity and exercise on
objectively-measured and patient-reported outcomes among patients with
melanoma. Methods: Searches were conducted in PubMed, CINAHL,
EMBASE, SPORTDiscus, and Web
of Science databases. This review included published data
involving physical activity or exercise and objectively-measured or
patient-reported outcomes of patients with cutaneous melanoma. The quality
of included studies was assessed using the McMaster University Critical
Appraisal Tool for Quantitative Studies. Results: Six studies including 882 patients with melanoma were included. Studies
presented heterogeneity of design with 2 cross-sectional surveys, 2
retrospective analyses, and 2 non-randomized intervention trials. No
statistically significant change in quality of life, fatigue, physical
function, cardiorespiratory fitness, body composition, psychological
distress, cognitive function, or treatment-related side-effects were
attributable to physical activity or exercise. Importantly, physical
activity or exercise during melanoma treatment or into survivorship did not
adversely impact patients/survivors. Conclusion: In summary, physical activity or exercise did not adversely impact quality of
life, objectively-measured or patient-reported outcomes in patients with
melanoma. In addition, there is a paucity of quality studies examining the
effects of physical activity or exercise on patients with melanoma
throughout the cancer care continuum.

Abstract
The present study was planned to detect the genes encoding carbapenemases, ESBLs and class 1 integron-integrase among bacteria obtained from retail goat meat. Fermenting and non-fermenting bacterial isolates (n = 57), recovered from 61 goat meat samples, were identified by 16S rRNA gene sequencing. Antimicrobial susceptibility of isolates was tested by the broth dilution method using ceftazidime, cefotaxime, meropenem and imipenem. Plasmids were isolated and tested for their physical characters. Plasmids were subjected to screening of carbapenemase, ESBL and intI1 gene. Conjugation assay was performed using blaNDM -positive isolates as the donor, and Escherichia coli HB101 as the recipient. Isolates showed the high rates of resistance to ceftazidime (77·2%), cefotaxime (70·2%), meropenem (22·8%) and imipenem (17·5%). They showed variability in number and size (~1 to >20 kb) of plasmids. Among all, 1, 4, 13 and 31 isolates showed the blaKPC , blaNDM , blaSHV and blaTEM genes, respectively. The blaKPC-2 gene was observed in one E. coli isolate. The blaNDM-1 gene was detected in Stenotrophomonas maltophilia (n = 2), Acinetobacter baumannii (n = 1) and Ochrobactrum anthropi (n = 1) isolates. These isolates co-harboured the blaTEM and blaSHV genes. The intI1 gene was detected in 22 (38·6%) isolates, and 16 of these isolates showed the carbapenemase and/or ESBL genes. The conjugative movement of blaNDM gene could not be proved after three repetitive mating experiments. The presence of genes encoding carbapenemases and ESBLs in bacteria from goat meat poses public health risks.

Abstract
OBJECTIVE Employ the Reach, Effectiveness, Adoption, Implementation, Maintenance framework to evaluate the effectiveness of a co-located exercise clinic model in increasing access to exercise for people undergoing cancer treatment in a private clinic in Western Australia. METHODS This retrospective evaluation utilised a mixed-method approach to gather feedback from key stakeholder groups involved with the exercise clinic. Questionnaires and workout summary sheets were gathered from 237 exercise clinic participants over the 50-month evaluation period. These were supplemented by survey results from 119 patients who received cancer treatment at the facility, and semi-structured interviews from seven radiation oncologists, eight nurses, and three accredited exercise physiologists involved with the exercise clinic. RESULTS The co-located clinic demonstrated positive outcomes related to effectiveness and adoption. Participant feedback indicated satisfaction with the exercise programming (effectiveness), and clinicians were receptive to referring patients to the clinic (adoption). However, no clear implementation or maintenance plan was employed and overall reach (12%) remained suboptimal throughout the evaluation period. CONCLUSION Co-locating an exercise clinic into a treatment facility does not in itself overcome the logistical challenges of providing integrated exercise services to people during cancer treatment. To enhance its utilisation, an implementation plan needs to accompany the intervention.

Abstract
The present study was aimed to detect the carbapenemase, extended-spectrum β-lactamase (ESBL), and intI1 gene of class 1 integron among fermenting (n = 61) and nonfermenting (n = 10) bacterial isolates recovered from water samples (n = 128). Isolates were identified by 16S rRNA sequencing. These isolates showed reduced-susceptibility to third-generation cephalosporins and carbapenems. The isolates varied in number and size of plasmids (2 kb to >20 kb). Plasmid DNA screening showed 5·6, 7, 11·2 and 26·7% prevalence of blaKPC , blaNDM , blaSHV and blaTEM genes respectively. Diverse blaNDM (blaNDM-1 and blaNDM-4 ) and blaSHV subtypes (blaSHV-2 and blaSHV-11 ) were recorded, unlike the single allelic blaKPC (blaKPC-2 ) and blaTEM (blaTEM-1 ) gene. Of the total 27 bla-gene-producing bacterial isolates, seven isolates co-harboured the carbapenemase genes (blaNDM or blaKPC or the both) along with the ESBL genes (blaSHV or blaTEM ). The intI1 gene of class 1 integron was detected among 12 (44·4%) of ESBL- and/or carbapenemase-harbouring isolates. Gene transferability was seen among four of the 10 Enterobacteriaceae donors. Carbapenemases and ESBLs with class 1 integron among aquatic environmental isolates raise the serious issue of the biosecurity and health of the ecosystem. SIGNIFICANCE AND IMPACT OF THE STUDY: Anthropologically affected and polluted environment harbours the resistance threats, where a diverse bacterial species maintain, develop and exchange genetic determinants that constitute a risk to human and ecological health. The antimicrobial resistance (AMR) in Enterobacteriaceae and non-Enterobacteriaceae bacteria caused the failure of the therapy of last resort (carbapenems) and thus lead to life-threatening infections affecting public health. Surveillance and monitoring of AMR could be important for epidemiological, diagnostic testing and control of pathogens. This is a point-prevalence study reporting the comparative occurrence and co-occurrence of carbapenemase and extended-spectrum β-lactamase genes among fermenting and nonfermenting bacteria isolated from the aquatic environment in India.

Abstract
Herein, a high temperature-induced phase transformation (PT) in chemically grown CdO thin films is demonstrated, and its corresponding electronic origin further investigated by density functional theory. In particular, the cubic rocksalt to hexagonal wurtzite PT in the CdO thin film annealed at 900 °C was confirmed by X-ray diffraction (XRD), which was consistent with the high-resolution transmission electron microscopy (TEM) results. Moreover, atomic force microscopy and scanning electron microscopy clearly evidenced the morphological evolution via the formation of a nanosheet network in the wurtzite-phase CdO film. The high temperature treatment also led to a significant enhancement in the optical band gap from 2.2 to 3.2 eV, as manifested by UV-visible spectroscopy. The enhanced surface roughness of the nanosheet caused a deviation in the net dipole moment, which may break the polarizable bonds and help in reducing the average dielectric constant, resulting in a band gap opening for the transformed phase. Furthermore, X-ray absorption spectroscopy at the oxygen k-edge revealed a notable shift in the inflection point of the absorption edge, while the X-ray photoelectron spectroscopy (XPS) Cd 3d and O 1s spectra suggested a gradual reduction in the CdO2 phase with an increase in annealing temperature. In addition, different complementary techniques including Rutherford backscattering and Raman spectroscopy were exploited to understand the aforementioned PT and its structural correlation. Finally, molecular dynamics simulation together with density functional theory calculation suggested that the symmetry modification at the Brillouin zone boundary provides a succinct signature for the PT in the CdO thin film.

Abstract
BACKGROUND Patients with advanced lung cancer have a high symptom burden, which is often complicated by coexisting conditions. These issues, combined with the indirect effects of cancer treatment, can cumulatively lead patients to continued deconditioning and low exercise capacity. This is a concern as exercise capacity is considered a measure of whole body health, and is critical in a patient's ability to participate in life activities and tolerate difficult treatments. There is evidence that exercise training improves exercise capacity and other outcomes, such as muscle force and health-related quality of life (HRQoL), in cancer survivors. However, the effectiveness of exercise training on these outcomes in people with advanced lung cancer is currently unclear. OBJECTIVES The primary aim of this review was to investigate the effects of exercise training on exercise capacity in adults with advanced lung cancer. Exercise capacity was defined as the six-minute walk distance (6MWD; in meters) measured during a six-minute walk test (6MWT; i.e. how far an individual can walk in six minutes on a flat course), or the peak oxygen uptake (i.e. VO₂peak) measured during a maximal incremental cardiopulmonary exercise test (CPET).The secondary aims were to determine the effects of exercise training on the force-generating capacity of peripheral muscles, disease-specific global HRQoL, physical functioning component of HRQoL, dyspnoea, fatigue, feelings of anxiety and depression, lung function, level of physical activity, adverse events, performance status, body weight and overall survival in adults with advanced lung cancer. SEARCH METHODS We searched CENTRAL, MEDLINE (via PubMed), Embase (via Ovid), CINAHL, SPORTDiscus, PEDro, and SciELO on 7 July 2018. SELECTION CRITERIA We included randomised controlled trials (RCTs) which compared exercise training versus no exercise training in adults with advanced lung cancer. DATA COLLECTION AND ANALYSIS Two review authors independently screened the studies and selected those for inclusion. We performed meta-analyses for the following outcomes: exercise capacity, disease-specific global HRQoL, physical functioning HRQoL, dyspnoea, fatigue, feelings of anxiety and depression, and lung function (forced expiratory volume in one second (FEV1)). Two studies reported force-generating capacity of peripheral muscles, and we presented the results narratively. Limited data were available for level of physical activity, adverse events, performance status, body weight and overall survival. MAIN RESULTS We identified six RCTs, involving 221 participants. The mean age of participants ranged from 59 to 70 years; the sample size ranged from 20 to 111 participants. Overall, we found that the risk of bias in the included studies was high, and the quality of evidence for all outcomes was low.Pooled data from four studies demonstrated that, on completion of the intervention period, exercise capacity (6MWD) was significantly higher in the intervention group than the control group (mean difference (MD) 63.33 m; 95% confidence interval (CI) 3.70 to 122.96). On completion of the intervention period, disease-specific global HRQoL was significantly better in the intervention group compared to the control group (standardised mean difference (SMD) 0.51; 95% CI 0.08 to 0.93). There was no significant difference between the intervention and control groups in physical functioning HRQoL (SMD 0.11; 95% CI -0.36 to 0.58), dyspnoea (SMD -0.27; 95% CI -0.64 to 0.10), fatigue (SMD 0.03; 95% CI -0.51 to 0.58), feelings of anxiety (MD -1.21 units on Hospital Anxiety and Depression Scale; 95% CI -5.88 to 3.45) and depression (SMD -1.26; 95% CI -4.68 to 2.17), and FEV1 (SMD 0.43; 95% CI -0.11 to 0.97). AUTHORS' CONCLUSIONS Exercise training may improve or avoid the decline in exercise capacity and disease-specific global HRQoL for adults with advanced lung cancer. We found no significant effects of exercise training on dyspnoea, fatigue, feelings of anxiety and depression, or lung function. The findings of this review should be viewed with caution because of the heterogeneity between studies, the small sample sizes, and the high risk of bias of included studies. Larger, high-quality RCTs are needed to confirm and expand knowledge on the effects of exercise training in this population.

Abstract
Background: Neoadjuvant chemoradiation treatment (CRT) in rectal cancer patients is associated with a reduction in physical capacity, lean mass and increased fatigue. As a countermeasure to these treatment-related adverse effects, we examined the feasibility and preliminary efficacy of a 10-week exercise program during CRT. Methods: Ten rectal cancer patients (7 men, aged 27-70 years, body mass index = 26.4 ± 3.8 kg/m2) receiving CRT undertook supervised resistance and aerobic exercise twice weekly. Assessments were undertaken pre- and post-intervention for upper and lower body muscle strength by 1-RM, muscle endurance, physical performance tests, body composition by dual X-ray absorptiometry, quality of life, and fatigue. Results: There was a significant loss in appendicular skeletal muscle (−1.1 kg, P = .012), and fat mass (−0.8 kg, P = .029) following CRT. Despite the loss in skeletal muscle, leg press (P = .030) and leg extension (P = .046) strength improved by 27.2% and 22.7%, respectively, and leg press endurance by 76.7% (P = .007). Changes in strength were accompanied by improved performance (P < .05) in 6-m fast walking speed (6.9%) and dynamic balance as determined by the 6-m backwards walk (15.5%). There was minimal change in quality of life and fatigue, and no adverse events related to training. Conclusions: Exercise during neoadjuvant CRT appears to be feasible and well tolerated in rectal cancer patients and may enhance physical function while minimizing adverse changes in body composition and cancer-related fatigue. These initial findings need to be confirmed in randomized controlled trials.

Abstract
Porcine reproductive and respiratory syndrome (PRRS) is an economically important transboundary viral disease of pigs confronting the swine industry worldwide. This study was aimed to assess the pathogenic potential of PRRS virus belonging to genotype 2 that emerged in India in 2013. Nine 6-week-old piglets were inoculated intranasally with 2 × 105.75 TCID50 /ml of PRRSV (Ind-297221/2013). Three piglets were kept as uninfected controls. Blood and nasal swabs were collected daily up to 7 days post-infection (dpi) and on alternate days subsequently. Piglets were necropsied for tissue sample collection either on death or after euthanasia on 7, 14 or 21 dpi (one uninfected control and three PRRSV-infected piglets per interval). The virus caused high fever, typical blue ear, weight loss, respiratory distress, diarrhoea and leucopenia between 2 and 8 dpi. Two infected piglets died (on 3 and 17 dpi) during the course of study. The presence of virus in serum and nasal secretion was observed up to 19 and 17 dpi, respectively, with the maximum load between 4 and 7 dpi. Seroconversion started 6 dpi and the mean PRRSV antibody titre reached up to 640 by 21 dpi. Virus load was highest in tonsils at all the intervals, whereas in spleen and lymph nodes load was higher in later intervals. Major microscopic lesions in PRRSV-infected piglets included moderate to severe interstitial pneumonia, lymphoid depletion in tonsils and lymph nodes (cystic), thymic atrophy, reactive hyperplasia followed by lymphoid depletion in spleen. PRRSV antigen was consistently demonstrated by immunoperoxidase test in the lungs, spleen, tonsils and lymph nodes. Antigen distribution was more widespread on 7 and 14 dpi than on 21 dpi. The findings establish that the Indian PRRSV is highly pathogenic to piglets.

Abstract
BACKGROUND Prostatectomy is associated with short- and long-term morbidity, which includes attenuation of muscle function and deterioration of lean body mass. Physical function is a known predictor of morbidity and mortality, with initial evidence indicating that presurgical exercise is associated with fewer postsurgical complications and shorter hospitalization. The aim was to determine the feasibility of a supervised presurgical exercise program for prostate cancer (PCa) patients scheduled for prostatectomy. METHODS Ten men (68+6.4 years old) with localized PCa undertook a 6-week resistance and aerobic exercise program prior surgery. Training was undertaken twice weekly and patients were assessed at baseline, presurgery, and 6 weeks postsurgery. Outcome measures included muscle and physical performance, body composition, urinary incontinence and questionnaire. RESULTS Muscle strength increased by 7.5% to 24.3% ( P < .05) from baseline to presurgery but decreased to pretraining levels postsurgery, except for knee extensor strength ( P = .247). There were significant improvements ( P < .05) in the 6-m fast walk (9.3%), 400-m walk (7.4%), and chair rise (12.3%) at presurgery. Following surgery, improvements in physical performance were maintained. There was no change in lean or fat mass prior to surgery, but lean mass declined by 2.7 kg ( P = .014) following surgery. There were no adverse effects from the exercise program. CONCLUSIONS Exercise undertaken prior to prostatectomy improved muscle and physical performance, with functional benefits maintained 6 weeks postsurgery. Presurgical exercise for PCa patients has the potential to facilitate recovery by improving physical reserve capacity, especially in men with poor muscle nd physical performance.

Abstract
This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: The primary aim of this study is to investigate the effects of exercise training on exercise capacity in adults with advanced lung cancer. Exercise capacity is defined as the Six‐Minute Walk Distance (6MWD; in meters) measured during a 6MWT (i.e. how far an individual can walk in 6 minutes on a flat course) or the peak oxygen uptake (i.e. VO₂peak) measured during a maximal incremental CPET. The secondary aims are to determine the effects of exercise training on the force‐generating capacity of peripheral muscles, HRQoL, dyspnea, fatigue, feelings of anxiety and depression, lung function, and physical activity levels in adults with advanced lung cancer.

Abstract
Draft genome sequence in pigeonpea offers unprecedented opportunities for genomics assisted crop improvement via enabling access to genome-wide genetic markers. In the present study, 421 hypervariable simple sequence repeat (SSR) markers from the pigeonpea genome were screened on a panel of eight pigeonpea genotypes yielding marker validation and polymorphism percentages of 95.24 and 54.11%, respectively. The SSR marker assay uncovered a total of 570 alleles with three as an average number of alleles per marker. Similarly, the mean values for gene diversity and PIC were 0.44 and 0.37, respectively. The number of polymorphic markers ranged from 39 to 89 for different parental combinations. Further, 60 of these SSRs were assayed on 94 genotypes, and model based clustering using STRUCTURE resulted in the identification of the two subpopulations (K = 2). This remained in close agreement with the clustering patterns inferred from genetic distance (GD)-based approaches i.e., dendrogram, factorial and principal coordinate analysis (PCoA). The AMOVA accounted majority of the genetic variation within groups (89%) in comparison to the variation existing between the groups (11%). A subset of these markers was implicated for hybrid purity testing. We also demonstrated utility of these SSR markers in trait mapping through association and bi-parental linkage analyses. The general linear (GLM) and mixed linear (MLM) models both detected a single SSR marker (CcGM03681) with R2 = 16.4 as associated with the resistance to Fusarium wilt variant 2. Similarly, by using SSR data in a segregating backcross population, the corresponding restorer-of-fertility (Rf) locus was putatively mapped at 39 cM with the marker CcGM08896. However, The marker-trait associations (MTAs) detected here represent a very preliminary type and hence demand deeper investigations for conclusive evidence. Given their ability to reveal polymorphism in simple agarose gels, the hypervariable SSRs are valuable genomic resource for pigeonpea research community, particularly in South Asia and East Africa where pigeonpea is primarily grown.

Abstract
BACKGROUND Cardiac muscle cryopreservation is a challenge for both diagnostic procedure requiring viable tissues and therapeutic advance in regenerative medicine. Mitochondria are targets of both direct and indirect damages, secondary to congelation per se and/or to cryoprotectant's toxic effects, which participate to diminution of viability and/or functioning of cells after freezing. At the cardiac muscle level, only one study had investigated mitochondrial respiration after cryopreservation. OBJECTIVE To determine the effect of cryopreservation on mitochondrial respiration of cardiac muscle. MATERIALS AND TMETHODS We recorded mitochondrial respiration through complexes I, II, III and IV along with mitochondrial coupling in fresh and cryopreserved rat left ventricles samples and assessed difference of the means, correlation and agreement between the measures in all samples. RESULTS Mitochondrial respiration was partly maintained up to 70% in cryopreserved samples whatever the substrate. A significant correlation was observed between fresh and cryopreserved samples (r = 0.71, p < 0.0001). However, mitochondrial coupling significantly decreased after cryopreservation (- 1.44 ± 0.15; p < 0.005) suggesting that mitochondrial intactness was not totally preserved by cryopreservation. Further, the fluctuations around the mean difference were wide (-14.06, +5.08 µmol/min/g), increasing with respiration rates (p < 0.0001). CONCLUSION Thus, fresh samples extemporaneous analysis should be preferred when available despite the fact that cryopreservation using DMSO partly protect cardiac mitochondrial respiration and coupling. These data support the interest to further refine cryopreservation methods.

Abstract
Background Malignant brain tumors are unpredictable and incurable, with 5-year survival rates less than 30%. The poor prognosis combined with intensive treatment necessitates the inclusion of complementary and supportive therapies that optimize quality of life and reduce treatment-related declines in health. Exercise therapy has been shown to be beneficial in other cancer populations, but no evidence is available for brain cancer survivors. Therefore, we report results from 2 preliminary cases. Methods Two female patients diagnosed with glioblastoma multiforme and oligodendroglioma participated in a structured and supervised 12-week exercise program. The program consisted of two 1-hour resistance and aerobic exercise sessions per week and additional self-managed aerobic sessions. Outcome measures of strength, cardiovascular fitness, and several psychological indicators (depression, anxiety, and quality of life) were recorded at baseline, after 6 weeks and at the conclusion of the intervention. Results Exercise was well tolerated; both participants completed all 24 sessions and the home-based component with no adverse effects. Objective outcome measures displayed positive responses relating to reduced morbidity. Similar positive responses were found for psychological outcomes. Scores on the Hospital Anxiety and Depression Scale showed clinically meaningful improvements in depression and total distress. Conclusion These findings provide initial evidence that, despite the difficulties associated with brain cancer treatment and survivorship, exercise may be safe and beneficial and should be considered in the overall management of patients with brain cancer.

Abstract
The effects of mitochondrial uncoupling on skeletal muscle mitochondrial adaptation and maximal exercise capacity are unknown. In this study, rats were divided into a control group (CTL, n = 8) and a group treated with 2,4-dinitrophenol, a mitochondrial uncoupler, for 28 days (DNP, 30 mg·kg−1·day−1in drinking water, n = 8). The DNP group had a significantly lower body mass ( P < 0.05) and a higher resting oxygen uptake (V̇o2, P < 0.005). The incremental treadmill test showed that maximal running speed and running economy ( P < 0.01) were impaired but that maximal V̇o2(V̇o2max) was higher in the DNP-treated rats ( P < 0.05). In skinned gastrocnemius fibers, basal respiration (V0) was higher ( P < 0.01) in the DNP-treated animals, whereas the acceptor control ratio (ACR, Vmax/V0) was significantly lower ( P < 0.05), indicating a reduction in OXPHOS efficiency. In skeletal muscle, DNP activated the mitochondrial biogenesis pathway, as indicated by changes in the mRNA expression of PGC1-α and -β, NRF-1 and −2, and TFAM, and increased the mRNA expression of cytochrome oxidase 1 ( P < 0.01). The expression of two mitochondrial proteins (prohibitin and Ndufs 3) was higher after DNP treatment. Mitochondrial fission 1 protein (Fis-1) was increased in the DNP group ( P < 0.01), but mitofusin-1 and -2 were unchanged. Histochemical staining for NADH dehydrogenase and succinate dehydrogenase activity in the gastrocnemius muscle revealed an increase in the proportion of oxidative fibers after DNP treatment. Our study shows that mitochondrial uncoupling induces several skeletal muscle adaptations, highlighting the role of mitochondrial coupling as a critical factor for maximal exercise capacities. These results emphasize the importance of investigating the qualitative aspects of mitochondrial function in addition to the amount of mitochondria.

Abstract
BACKGROUND Recent reviews suggest that enhancing fitness and functional capacity prior to surgery can accelerate post-surgery recovery and reduce mortality. However, the effect of pre-surgical exercise interventions in cancer patients is not fully explained. The aim of this paper is to systematically review the available literature regarding pre-surgery exercise training interventions in cancer patients and examine their effects on physiological outcomes as well as quality of life (QOL) and length of hospital stay. METHODS Relevant studies were identified through a search on MEDLINE, PreMEDLINE, AMED, MEDLINE Daily Update, CINAHL and SPORTDiscus. All randomized controlled trials (RCTs) and non-RCTs that had some form of physical exercise undertaken prior to surgery were included. Descriptive characteristics such as participant characteristics, study design, types of cancer, length of study, and primary outcomes were extracted. Methodological rigour was assessed using a modified Delphi List. Due to the heterogeneity and the dearth of pre-surgical studies, we were limited to a systematic review rather than a meta-analysis. RESULTS Eighteen studies were included consisting of a total of 966 participants. Lung cancer studies were the predominant group represented. Most of the studies prescribed an aerobic intervention programs done prior to surgery. Mode, frequency, duration, and intensity of exercise intervention varied across the different cancer groups. The majority of studies showed preliminary positive change in clinical outcomes with significant improvements in the rate of incontinence, functional walking capacity and cardiorespiratory fitness. CONCLUSION Pre-surgical exercise may benefit cancer patients through positive effects on function and physical capacity. Surgical oncologists may consider pre-surgical exercise interventions as a potential adjuvant therapy to improve patients' outcomes.

Abstract
The effect of swift heavy oxygen ion irradiation of hydroxyapatite on its in vitro bioactivity was studied. The irradiation experiment was performed using oxygen ions at energy of 100 MeV with 1 x 10(12) and 1 x 10(13) ions/cm2 fluence range. The irradiated samples were characterized by glancing angle X-ray diffraction (GXRD), photoluminescence spectroscopy (PL) and scanning electron microscopy (SEM). GXRD showed that irradiated samples exhibited better crystallinity. The irradiated samples revealed an increase in PL intensity. In addition, the irradiated hydroxyapatite was found to have enhanced bioactivity.

Abstract
An in situ x-ray diffraction (XRD) setup is designed and installed in the materials science beam line of the Pelletron accelerator at the Inter-University Accelerator Centre for in situ studies of phase change in swift heavy ion irradiated materials. A high vacuum chamber with suitable windows for incident and diffracted X-rays is integrated with the goniometer and the beamline. Indigenously made liquid nitrogen (LN2) temperature sample cooling unit is installed. The snapshots of growth of particles with fluence of 90 MeV Ni ions were recorded using in situ XRD experiment, illustrating the potential of this in situ facility. A thin film of C60 was used to test the sample cooling unit. It shows that the phase of the C60 film transforms from a cubic lattice (at room temperature) to a fcc lattice at around T=255 K.

Abstract
In the present work, magnetic force microscopy is employed to investigate the magnetic ordering in ion irradiated fullerene films. It is observed that magnetic domain size is approximately 100-200 nm and magnetic signal is stronger at the domain boundaries. Magnetic signal arise in irradiated films is confirmed by magnetic measurements using a superconducting quantum interference device which increases with the ion fluence. The induced magnetism is possibly due to structural defects in the amorphous carbon phase formed by ion irradiation.

Abstract
A line x tester analysis of combining ability involved five male-sterile lines from different sources and 10 inbreds of Pearl millet developed at Hissar (India). Additive x additive and additive x dominance types of gene interaction were found to predominate in the material under study. A high degree of association was found between general combining effects and the mean performance of lines and testers over crosses but no association was observed betweenper se performance of the crosses and their specific combining ability effects. Among the male sterile lines, L-110 proved to be the best general combiner, whereas H-297, followed by H-198, was the best of the inbreds. The crosses L-110 x H-440, L-110 x H-406, 18D2A x H-297, 18 A x H-198 and L-110 x H-297, were superior to the released variety, Hybrid-1, used as control.
