Abstract
The knowledge of pollen morphology, suitable storage condition, and species compatibility is vital for a successful grapevine improvement programme. Ten grape genotypes from three different species, viz., Vitis vinifera L., Vitis parviflora Roxb., and Vitis champini Planc., were studied for their pollen structure and pollen storage with the objective of determining their utilization in grape rootstock improvement programs. Pollen morphology was examined through the use of a scanning electron microscope (SEM). The viability of the pollen was assessed using 2,3,5-triphenyltetrazolium chloride (TTC). In vitro pollen germination was investigated using the semi-solid medium with 10 % sucrose, 100 mg/L boric acid, and 300 mg/L calcium nitrate. The results revealed variations in pollen micro-morphology in 10 genotypes, with distinct pollen dimensions, shapes, and exine ornamentation. However, species-wise, no clear difference was found for these parameters. Pollen of V. parviflora Roxb. and Dogridge was acolporated and did not germinate. The remaining eight genotypes exhibited tricolporated pollen and showed satisfactory in vitro pollen germination. Storage temperature and duration interactions showed that, at room temperature, pollen of most of the grape genotypes can be stored for up to 1 day only with an acceptable pollen germination rate (>30 %). However, storage for up to 7 days was successfully achieved at 4 °C, except for 'Pearl of Csaba'. The most effective storage conditions were found to be at -20 °C and -196 °C (in liquid N2), enabling pollen storage for a period of up to 30 days, and can be used for pollination to overcome the challenge of asynchronous flowering. Four interspecific combinations were studied for their compatibility, among which V. parviflora Roxb. × V. vinifera L. (Pusa Navrang) and V. parviflora Roxb. × V. champini Planc. (Salt Creek) showed high cross-compatibility, offering their potential use for grape rootstock breeding. However, V. parviflora Roxb. × V. vinifera L. (Male Hybrid) recorded the lowest compatibility index among studied crosses. In the case of self-pollinated flowers from V. parviflora Roxb. and V. parviflora Roxb. × V. champini Planc. (Dogridge), pollen failed to germinate on the stigma due to male sterility caused by acolporated pollen. As a result, the flowers of these genotypes functioned as females, which means they are ideal female parents for grape breeding without the need for the tedious process of emasculation.

Abstract
Background Scotland first demonstrated that adherence to nationally agreed hip fracture standards improve patient survival, reduces the duration of admission, and reduces the need for high dependency care. Our study aims to assess adherence to the Irish Hip Fracture Standards (IHFS) in our hospital for 2021 amidst the COVID-19 pandemic, translating to improved clinical outcomes for our patients. Methods The IHF database was retrospectively analysed, comparing quarters 1-4 in 2021 with our 2020 results. Results IHFS1, patient time to the ward < 4hours, was maintained at 67% in 2021 versus 71% overall in 2020. There was improvement in IHFS2, time to surgery within 48 hours, up to 73% in 2021 versus 66% in 2020. IHFS3 was 4% in 2021 versus 3% overall in 2020. Further improvements were noted for IHFS4, with 95% of patients reviewed by a Geriatrician in 2021 versus 87% in 2020. IHFS5 also improved with 97% of patients receiving a bone health assessment in 2021 versus 87% in 2020. Moreover, IHFS6, improved with 97% of patients undergoing a specialised falls assessment in 2021 versus 87% in 2020. Conclusion The improvement in 2021 figures is reflective of the return of redeployed services during the COVID-19 pandemic inclusive of the Orthogeriatric Service, the Fracture Liaison Service Advanced Nurse Practitioner, the Trauma Co-ordinator, and the specialist Orthopaedic ward complete with its Orthopaedic nurses and Multi-Disciplinary Team, and improved Emergency Department pathways. These continued improvements in the IHFS further emphasise that success is dependent on a team that is joined at the hip

Abstract
Abstract
Background
Nationally agreed hip fracture standards have contributed to the improvement of outcomes in hip fracture patients. In 2020, our hospital was awarded “The Golden Hip” for achieving highest compliance with Irish Hip Fracture Standards (IHFS) nationally for 2019.
Methods
Data from the Irish Hip Fracture Database (IHFD)was retrospectively analysed to assess our performance in 2020 versus 2019 in hip fracture patients over sixty. Multiple quality improvement interventions were put in place throughout 2019 to ensure improvement in IHFS1-6 compliance: Creation of the Hip Fracture Pathway Subgroup, IHFS 1 Breaches Audit, Orthogeriatric input at Orthopaedic inductions, weekly Multi-disciplinary Team meetings, a Nutritional Hip Fracture Pathway and addition of the Fracture Liaison Service Advanced Nurse Practitioner.
Results
There were 239 hip fracture patients in 2020 vs 249 in 2019. IHFS1 compliance improved with the percentage of patients admitted to the Orthopaedic ward within 4 hours increasing to 71% in 2020 from 56% in 2019. There was improvement in IHFS2-time to surgery <48 hours- 66% in 2020 vs 60% in 2019. IHFS3-pressure ulcer rate-was at the national average, 3% in 2020 vs 2% in 2019. IHFS4 (reviewed by a Geriatrician), IHFS5 (received a bone health assessment) and IHFS6 (received a specialised falls assessment) were lower overall; 87% in 2020 vs 98% in 2019. For all quarters (Q),43% of patients met all IHFS in our hospital in 2020 vs 32% in 2019, resulting in €90,000 in Best Practice Tariff funding.
Conclusion
Lower results for IHFS 4,5 and 6 reflect the arrival of the COVID-19 pandemic which led to redeployment of the Orthogeriatric Service and redeployment of the MDT from end of Q1 to Q3. When services in 2020 were preserved,1 in 2 hip fracture patients met all IHFS, vs 1 in 3 patients in 2019. Despite the pandemic, we continued to achieve the highest level of IHFS compliance nationally, being awarded a second consecutive “Golden Hip” for 2020.

Abstract
Locoregional recurrences following surgery for esophageal cancers represent a significant clinical problem with no standard recommendations for management. We conducted this systematic review and meta-analysis with the objective of studying safety and efficacy of salvage radiotherapy in this setting. All prospective and retrospective cohort studies, which studied patients who developed locoregional recurrence following initial radical surgery for esophageal cancer and subsequently received salvage radiation therapy (RT)/chemoradiation with all relevant information regarding survival outcome and toxicity available, were included. The quality of eligible individual studies was assessed using the Newcastle-Ottawa Scale score for risk of bias. R package MetaSurv was used to obtain a summary survival curve from survival probabilities and numbers of at-risk patients collected at various time points and to test the overall heterogeneity using the I2 statistic. Thirty studies (27 retrospective, 3 prospective) published from 1995 to 2020 with 1553 patients were included. The median interval between surgery and disease recurrence was 12.5 months. The median radiation dose used was 60 Gy and 57% received concurrent chemotherapy. The overall incidence of acute grade 3/4 mucositis and dermatitis were 8 and 4%, respectively; grade 3/4 acute pneumonitis was reported in 5%. The overall median follow-up of all studies included was 27 months. The 1-, 2- and 3-year overall survival (OS) probabilities were 67.9, 35.9 and 30.6%, respectively. Factors which predicted better survival on multivariate analysis were good PS, lower group stage, node negativity at index surgery, longer disease-free interval, nodal recurrence (as compared to anastomotic site recurrence), smaller disease volume, single site of recurrence, RT dose >50 Gy, conformal RT, use of concomitant chemotherapy and good radiological response after radiotherapy. Salvage radiotherapy with or without concomitant chemotherapy for locoregional recurrences after surgery for esophageal cancer is safe and effective. Modern radiotherapy techniques may improve outcomes and reduce treatment-related morbidity.

Abstract
A schwannoma is a benign, encapsulated tumour that is derived from neural sheath (Schwann) cells. Approximately 25-40% of schwannomas occur in the head and neck. The most common site is the parapharyngeal space of the neck; oropharyngeal occurrence is extremely rare. Among the various histological types of schwannomas reported to date, the ancient (degenerative) variant is the most rare. To our knowledge, this is the first report of an ancient schwannoma in the parapharynx with an extensive oropharyngeal component causing dysphagia. Dysphagia was the prominent symptom because of the location and volume of the lesion. The tumour was excised via a transcervical approach.
