Pomegranate (Punica granatum) is an important exportable fruit crop of India that faces major losses when infected by fungal wilt and bacterial blight. The present investigation is aimed to isolate and identify the causative organism of the plant disease infecting the stem of pomegranate. The identification based on microscopic, morphological characterization and 18SrRNA sequencing confirms as Mariannaea elegans. The crude extracts of various leaves of plants viz Psidium guajava, Picrorhiza kurroa and Piper betel were used to evaluate antifungal activity using agar well diffusion method. Results confirm that ethanolic extract of Piper betel extract (0.5mg/ml) show zone of inhibition against Mariannea elegans. The research demonstrates that commonly used fungicides viz., Manocozeb/ Matalxy and Carbendazim showed very little inhibition as compared to the Piper betel ethanolic extracts and hence the latter proves to be a better and eco-friendlier control alternative.
The present study was also aimed at finding remedies for bacterial blight. The blight pathogen was isolated from the fruit pericarp and identified using morphological and biochemical characters to be Xanthomonas axonopodis pv. punicae (Xap). Nanoparticles synthesized using green method, Copper oxide nanoparticles (1mg/ml) synthesized using Azadirachta indica leaf extract showed excellent inhibitory effect against the blight pathogen as compared to Bordeaux mixture, commonly used as an antimicrobial spray by farmers.

Authors: Elsa Prisanda  , Rury Febrina
Published: September 2021

Penerapan teknologi informasi sangat dibutuhkan di dalam penyelenggaraan pemerintah desa. Terutama di bidang jasa publik. Penyelenggaraan jasa publik dilakukan oleh pemerintah desa dalam kemudahan akses informasi dan komunikasi. Namun, lain halnya jika jasa publik yang dijalankan tersebut mengalami beberapa kendala seperti kurangnya keterbukaan informasi kepada publik, pelayanan publik yang memakan waktu yang lama, proses yang berbelit-belit, serta layanan yang tak dapat diakses memicu tingkat kepuasan masyarakat berkurang. Hal itu disebabkan oleh banyak faktor, salah satunya, pemerintah desa masih menggunakan sistem manual, yang menghambat proses kinerja pegawai desa dalam memberikan pelayanan publik yang efektif dan efisien. Untuk menjawab masalah yang terjadi, maka Pemerintah Desa menciptakan suatu aplikasi SISPEDAL untuk mempermudah administrasi desa. Penelitian ini menggunakan pendekatan Kualitatif. Teknik pengumpulan data dengan mempelajari literatur dan menggunakan penelitian sebelumnya. Penelitian ini menggunakan teori elemen sukses E-Government dalam sektor publik, yaitu support, capacity, dan value. Hasil penelitian menunjukkan bahwa melalui aplikasi SISPEDAL resmi pemerintah desa Aliantan, pemerintah desa dapat meningkatkan transparansi dalam konteks good village governance dilingkungan pemerintahan desa Aliantan.

The Learning Advisory Program Club Events and Well-Being: Regular Clubbers’ Reflections on Their Experiences
Authors: Guven-Yalcin Gamze
Published: September 2021

From a sociocultural perspective of autonomy, it is vital that learners can access information, identify their values, know themselves, and manage their cognitive and affective states in their learning environment, and voice their opinions within their community of practice. To provide its learners with autonomy-supportive and structured environments within its specific context, the Learning Advisory Program Unit (LAP) of Ankara Yıldırım Beyazıt University School of Foreign Languages (AYBU SFL) designed an extracurricular program, the LAP Club, which incorporated self-determination theory (SDT), PERMA-the five pillars of well-being, and intentional reflective dialogue (IRD) to promote advising practices. The resulting content was delivered following the phases defined in the equipped for future (EFF) framework and standards. In this qualitative research project investigating the participants’ perceptions of the efficiency of the program in promoting their well-being, a questionnaire developed based on PERMA profiler by Butler and Kern (2016) was administered to five regular participants in their L1, Turkish. A translation method was applied to the data by the researcher to manage sensitive qualitative data and enhance research transparency. The findings indicate that the awareness gained with notions of well-being improves the learning process and develops the sense of self-determination with high levels of well-being.

Attention control in a demanding dynamic time-sharing environment: An eye-tracking study
Authors: Kulomäki Jaakko , Oksama Lauri , Rantanen Esa , Hyönä Jukka
Published: September 2021

In this study, we examined different models of cognitive control in dynamic time-sharing situations. We investigated attentional allocation by registering participants’ eye movements while they performed a new time-sharing task that forced them to solve resource conflicts between subtasks through prioritization. Participants were monitoring four subtasks each requiring different amounts of visual attention and response frequencies. Participants’ attention allocation was operationalized in terms of the time spent dwelling on subtasks, the rate they visually sampled the tasks, and the duration of dwells. Additionally, the accuracy of responses and efficiency of time-sharing were estimated. In Experiment 1, we studied adaptation to a time-sharing environment in which priority order of the subtasks was kept constant from trial to trial. We found that the participants sampled the most important subtasks more frequently, spent more time on them, and shifted their gaze earlier to them than to less important subtasks. That is, they allocated their attention according to the subtask priorities. In Experiment 2, subtask priorities changed from trial to trial. Despite the higher demands of the constantly changing situation, participants again adapted to the varying priorities of the subtasks almost instantly. Our results suggest that performance in complex and dynamic time-sharing situations is not managed by a system relying on liberal resource allocation policies and gradual learning. Instead, the participants’ rapid adaptation is more consistent with tighter executive and authoritative control and intelligent use of prioritization information.

Published: September 2021

The Neonicotinoid insecticides are presently used in great amounts, but this can be a problem when the possible risks of occupational and environmental contamination are considered. The objective of this study was to investigate the potential adverse effects of sublethal doses of Thiamethoxam insecticide on serum biochemical, oxidative stress and histological alterations in male albino mice via 28-day repeated-dose oral toxicity study. The possible ameliorative effect of selenium plus vitamin E against the harmful effects of Thiamethoxam was also investigated. Mice in Thiamethoxam-treated groups received three sublethal doses (6, 12, and 30 mg/kg b.w./day). Animals in another group were orally co-administered selenium + vitamin E with the higher dose of insecticide. The results showed that Thiamethoxam significantly (p < 0.05) increased cholesterol levels and liver enzyme activities, in dose-dependent manner, compared to those of the control group. Levels of creatinine were not significantly changed, whereas uric acid increased at high doses. The oxidative stress parameters were significantly increased in association with decrease in total antioxidants level. The histological analysis revealed that the higher dose induced various alterations in tissues of vital organs, i.e. liver, kidney, lung and testes. Interestingly, the ameliorative effect of selenium + vitamin E in restoring the oxidative stress parameters was reflected by reducing severity of histopathological lesions. In conclusion, it appears that the sublethal dose < 6.0 mg/kg b.w./day, in repeated dose 28-day oral toxicity study, in male albino mice may be considered as No-Observed-Adverse-Effect-Level (NOAEL) of Thiamethoxam. Additionally, the antioxidant selenium, in mixture with vitamin E, showed an ameliorative effect against Thiamethoxam-induced toxicity.

Published: September 2021

Investigations on the characteristics of fluid flow in manufacturing processes are essential since it will determine the quality of the end products. The flow might be involved whether the Newtonian (viscous) or non-Newtonian fluid moving over the different body depending on the process activities. Since the experimental works sometimes costly and hazardous, the study via mathematical approach is necessary to counter the limitations. Hence, this paper aims to investigate the flow at lower stagnation point over a horizontal circular cylinder on Brinkman Viscoelastic fluid embedded in porous medium. Mathematical model is constructed in terms of partial differential equations with some physical conditions to represent the condition of the problem. An appropriate non-dimensional variable is introduced to transform the model into the solvable system which is in less complexity, and then the system is solved using the Runge-Kutta-Fehlberg method. The numerical solutions for the temperature and velocity profiles as well as skin friction and heat transfer coefficient are computed and presented in graphical and tabular form. The feature of the flow and heat transfer characteristics for various values of mixed convection, Brinkman and viscoelastic parameter are analysed and discussed. This study has found that the incremented Brinkman and viscoelastic parameter have declined the fluid velocity while opposite trend is observed for temperature distribution. The theoretical results produced are relevance to researchers and engineers. It can be used for comparative purposes in data validation or experimentation study.

Generation of High-frequency Whistler Waves in the Earth’s Quasi-perpendicular Bow Shock
Authors: Page Brent , Vasko Ivan Y. , Artemyev Anton V. , Bale Stuart D.
Published: September 2021

We use observations from the Magnetospheric Multiscale spacecraft to identify a free energy source for high-frequency whistler waves in the Earth’s quasi-perpendicular bow shock. In the considered measurements, whistlers propagate both parallel and antiparallel to the background magnetic field
B

0 with frequencies around 100 Hz (0.15 f
ce, where f
ce is the electron cyclotron frequency) and amplitudes between 0.1 and 1 nT. Their growth can be attributed to localized pitch angle anisotropy in the electron velocity distribution function that cannot be precisely described by macroscopic parameters like heat flux or temperature anisotropy. However, the presence of heat flux along −
B

0 does create preferential conditions for the high-frequency whistler waves that propagate in this direction. These waves are directed partially toward the shock, meaning they can scatter electrons that are streaming from the shock. This prolongs the time the electrons spend in the shock transition region and thereby promotes electron energization.
Farmers’ knowledge, perception and management practices of fall armyworm (Spodoptera frugiperda Smith) in Manica province, Mozambique
Authors: Caniço Albasini , Mexia António , Santos Luisa
Published: September 2021

This study aimed to gather information about farmers’ knowledge, perception and management practices of the newly introduced insect pest, the fall armyworm Spodoptera frugiperda Smith (Lepidoptera: Noctuidae) in Manica province, Mozambique. A total of 200 smallholder farmers with experience in maize cultivation were surveyed using a semi-structured questionnaire. The survey was conducted between May and August 2019 in four districts: Macate, Manica, Sussundenga and Vanduzi. Most farmers were unable to morphologically identify fall armyworm (FAW) (from 93.9% in Vanduzi to 98.0% in Manica). Most farmers have experienced FAW damage in their farms (from 92% in Macate to 98.0% in Manica). Maize is mostly planted in October and November (from 44.0% in Sussundenga to 60.0% of farmers in Manica), but the highest infestation period is believed to be between November and February. With the exception of Vanduzi where 65.3% of farmers apply insecticides, most farmers in other districts do not use any method to control FAW (from 60.8% in Macate to 88.0% in Manica and Sussundenga respectively). Among those applying insecticides, from 65.0% in Manica to 75.0% in Vanduzi have confidence in the efficiency of the insecticides being used against FAW. Most farmers reported an increase in the spread of FAW. The lack of financial resources is reported as the main constraint in the fight against FAW. This study is the first of its nature in the province of Manica and provides valuable information that may support extension services and researchers when designing FAW management options for local smallholder farmers.

Faut-il fusionner les ministères chargés de l’Environnement et de la Santé ? Essai d’analyse à la lumière de la fusion engagée en 2007 entre les ministères chargés de l’Environnement et de l’Énergie
Authors: Lavergne Richard
Published: September 2021

La crise de la Covid-19 a été vue par certains comme le cumul de plusieurs crises, dont une crise sanitaire et environnementale. Au moment où s’amorce la sortie de crise, il peut être tentant de restructurer l’organisation administrative relative à la santé et à l’environnement, à l’image de ce qui s’est produit en 2007 avec la fusion des ministères chargés de l’Énergie et de l’Environnement. L’auteur observe que les politiques de santé et de l’énergie présentent des points communs par rapport aux questions environnementales. Mais se référant à la fusion considérée, qui, décidée par le Président de la République, Nicolas Sarkozy, a donc conduit à la création en 2007 d’un grand ministère chargé notamment de l’Énergie et de l’Environnement, l’auteur considère que la politique de santé n’aurait rien à gagner d’une telle fusion.
Vers une écologisation de la gouvernance de la santé
Authors: Blanc Nathalie
Published: September 2021

Cet article traite de l’évolution de la relation entre la nature et l’environnement urbain au cours des XIX e et XX e  siècles, et même jusqu’au XXI e  siècle en Europe et aux États-Unis, une relation qui a été principalement abordée en termes de santé publique. L’aménagement de l’espace et les règles d’urbanisme ont longtemps été les outils d’un engagement politique s’intéressant à toutes les dimensions de la vie afin de surveiller et contrôler les atteintes qui pourraient lui être portées, et in fine de la préserver. La prise en compte des dimensions environnementales dans les politiques territoriales de santé conduit à revoir les liens aménagement/nature ainsi que le rôle des différents acteurs impliqués dans les politiques de santé.
Le principe d’analogie en littérature comparée et l’unicité de l’œuvre
Authors: Franco Bernard
Published: September 2021

Le point de départ de la démarche comparative semble être la ressemblance. Plus généralement, l’analogie est à la fois principe créateur et modalité de lecture d’une œuvre : on écrit d’après une littérature existante, on lit d’après ses lectures précédentes. Néanmoins, le sens propre à une œuvre et qui garantit son unicité se dégage de la différence. Par l’étude des parallèles, qui se distingue de celle des dettes, des sources et de tout type de dérivation, la poétique comparée, derrière le constat de l’analogie, tire précisément l’interprétation des œuvres de l’analyse des différences.
Variation in Literary Exchanges and the Formation of World Literary Canons
Authors: Cao Shunqing , Du Hongyan
Published: September 2021

David Damrosch affirme que la littérature mondiale se construit à travers la circulation, la traduction et la lecture de diverses littératures nationales. En fait, le concept de littérature mondiale met aujourd’hui essentiellement l’accent sur l’échange, le dialogue et l’inspiration mutuelle entre les littératures nationales. Dans le processus d’échanges littéraires, le canon littéraire mondial prospectif n’est pas seulement déterminé par l’autre, il a également un impact important sur l’autre. Fondée sur la communication et l’interaction entre les différentes littératures nationales, et tenant compte de l’hétérogénéité culturelle généralement ignorée par les études de littérature comparée, la théorie de la variation insiste sur l’étude des variations apparaissant dans les échanges littéraires internationaux, interlinguistiques et interculturels en général. Observant le phénomène de variation dans les échanges littéraires internationaux, interculturels et interlinguistiques, cet article pose que la variation dans les échanges littéraires est indispensable à la formation des canons littéraires mondiaux.
Chinese Philosophical Foundation of the Variation Theory of Comparative Literature
Authors: Wang Chao
Published: September 2021

La théorie des variations a suscité un grand intérêt dans les études internationales sur la littérature comparée ; il demeure néanmois un certain espace pour une exploration et un développement plus poussés. L’élaboration théorique de la littérature comparée repose en général sur des sources philosophiques sous-jacentes. Par exemple, les études d’influence issues de l’école française reposent sur la philosophie positiviste, et les études de parallèles propres à l’école américaine sont fondées sur l’herméneutique et l’esthétique de la réception. De fait, une théorie des variations est introduite dans le contexte académique chinois. Peut-on alors identifier son fondement philosophique chinois ? Dans l’ensemble, il ne provient pas d’une école de philosophie moderne ou contemporaine, mais il est enraciné dans les idées de variation qui prennent leur cohérence dans les discours philosophiques chinois anciens, tels que « Trois connotations de changements » (易 之 三名). Ces expressions philosophiques ont fourni une matière idéologique et un socle méthodologique pour la théorie des variations.
Différenciation, dialogisme, diversalité. Paradigmes pour un comparatisme différentiel et plurilingue
Authors: Heidmann Ute
Published: September 2021

La différenciation est une notion relationnelle qui, au lieu d’opposer le même et le différent , désigne le processus qui mène de l’un à l’autre. L’évolution même des langues, des littératures et des cultures est sous-tendue par un tel processus complexe de différenciation. Les analyses comparatives effectuées dans cette optique permettent de percevoir que toutes les pratiques littéraires évoluent sur le mode d’un dialogue constitutif avec d’autres langues, d’autres littératures et d’autres cultures. Repenser le monde (avec Chamoiseau, Bernabé et Confiant) en termes de diversalité au lieu d’ universalité suppose la reconnaissance de la diversité comme dynamique fondamentale de l’humanité et non plus comme exception par rapport à une prétendue universalité.
Using organic wastes as feed substrate for black soldier fly larvae
Authors: Msangi J.W. , Mweresa C.K. , Ndong’a M.F.O.
Published: September 2021

Feeding black soldier fly larvae (BSFL) on locally available organic wastes has the potential of providing an alternative source of protein to fishmeal and soybean used in animal feed formulation. This can also mitigate against increasing accumulation of organic wastes and reduce high costs associated with their disposal. This study assessed the effects of three locally available organic waste substrates namely Irish potato peels, kale remains and bovine ruminal content versus chick mash as a positive control on larval weight gain, prepupal yield, substrate reduction rate, bioconversion rate and conversion ratio of BSFL. Analysis of variance (ANOVA) was used to determine whether organic feed substrates had significant effects on BSFL while Tukey HSD, post-hoc test was applied for multiple comparisons and mean separation atP<0.05. Organic waste feed substrates influenced larval weight gain and prepupal yield (P<0.01), biomass reduction rate (P=0.04), bioconversion rate (P=0.01) and conversion ratio (P=0.04) of BSFL produced. Kale remains performed better than Irish potato peels and bovine ruminal contents implying that they can be enriched to provide an alternative feed for BSFL instead of chick mash. This study demonstrated that the three locally available organic waste substrates can be used to feed BSFL for sustainable production of animal feed. Black soldier fly larvae have the potential of providing a viable solution for degradation and disposal of ever-increasing quantities of organic wastes in the markets, towns and cities of sub-Saharan Africa.

This study determined if yellow mealworm larvae (YML) grown on deoxynivalenol (DON) contaminated wheat would affect broiler chicken performance. The YML were reared on wheat with low (LDW; 630 μg/kg) or high (HDW; 30,730 μg/kg) DON concentrations. The DON concentrations in the dried insect meals were 0 or 17.5 μg/kg for YML grown on LDW and HDW, respectively. Seventy-five male Ross 708 broilers were randomly placed into 15 cages and reared on one of three diets from day 1-35 (five replications/treatment). On day 14, broiler numbers were reduced to four per cage. The diets consisted of a control containing no YML meal (CD) and two diets containing 5% YML meal produced on either LDW (LMD) or HDW (HMD). Feed intake and body weight (BW) were measured over the duration of the experiment to calculate feed to gain ratio (F:G). On day 35, all birds were slaughtered and dissected to collect weights of the breasts, thighs, drums, wings, abdominal fat pads, and organs. Crude protein retention was higher in birds fed the LMD and HMD treatments compared to CD (P=0.0091). Dry matter retention was higher in the HMD diet compared to the CD and LMD diets (P=0.0046). Feed intake was lower in birds fed HMD compared to CD and LMD (P=0.0031) although final BW was not reduced. In conclusion, dietary inclusion of YML did not affect the growth, meat yield or organ weights of the birds. The YML reared on DON-contaminated wheat (up to 30,730 ug/kg) and included in broiler diets at 5% could be an effective means of converting salvage wheat into a safe and sustainable source of protein.

Insect production is generally a monoculture where insects are kept in an enclosed environment with a stable climate to maximise production. To maintain these conditions air treatment is necessary, which results in high operational costs. Combining insect rearing with hydroponic greenhouse cultivation (HGC) of fruit vegetables might offer an opportunity for cost reduction. Fruit vegetables generally require more elevated air temperature, while leaving enough space under the substrate supporting gutters to allow insect rearing. In this study the feasibility of combining both production systems was evaluated with mealworms (Tenebrio molitor) and cucumber HGC serving as model species. The influence of the greenhouse climate was assessed by rearing mealworms simultaneous at two locations (a climate room and a cucumber HGC). Furthermore, pruning waste and aesthetically declined fruits could serve as a feed for insects. This was tested by comparing 4 different wet feeds (whole and mashed cucumber pruning, tomatoes and agar-agar). Larval growth was monitored and at harvest the mealworm yield was compared among treatments. Mealworm growth in the greenhouse was on average 8.1% slower than growth in a climate room even though the average ambient temperature in the greenhouse was lower and more variable (22.1±3.30 °C standard deviation compared to 27.0±0.34 °C). Moreover, the results showed that the tested HGC residues can be used as wet feed given that mashed cucumber pruning gave similar results as agar-agar (control) and tomatoes even outperformed the control significantly in terms of growth. ‘Entomoponics’ is introduced as the name for the combination of insect production and HGC of vegetables as a way to create added value in unused heated space inside a greenhouse and valorise greenhouse residues.

Authors: Shin So Young , Kim Joo Hee
Published: September 2021

The current study aimed to assess relationships among role conflict, nursing professionalism, nursing work environment, and retention intention of nurses at long-term care (LTC) hospitals. Participants comprised 183 nurses at nine LTC hospitals located in Busan, Korea. Data were collected using a structured self-report questionnaire and analyzed using descriptive statistics,
t
test, one-way analysis of variance, Pearson's correlation coefficient, and multiple linear regression. Retention intention had a signifi-cant positive correlation with nursing professionalism (
r
= 0.39,
p
< 0.001) and nursing work environment (
r
= 0.51,
p
< 0.001). Nursing work environment had a significant negative correlation with role conflict (
r
= −0.30,
p
< 0.001) and a significant positive correlation with nursing professionalism (
r
= 0.48,
p
< 0.001). In the final multiple regression analysis, factors influencing retention intention of participants included number of beds (β = −0.15
p
< 0.026), nursing professionalism (β = 0.19,
p
= 0.007), and nursing work environment (β = 0.36,
p
< 0.001). The explanatory power of number of beds, nursing professionalism, and nursing work environment on retention intention was 34% (F = 16.66,
p
< 0.001). Improving nursing professionalism and nursing work environment of nurses at LTC hospitals will ultimately enhance their retention intention and positively impact the quality of gerontological nursing care. [

The purpose of this study was to examine current literature regarding the efficacy of total knee arthroplasty for patients with rheumatoid arthritis. Studies that assessed total knee arthroplasty outcomes in patients with rheumatoid arthritis were identified on MEDLINE from January 2009 to November 2018. All 4 studies that assessed knee pain and 9 of 11 studies that assessed knee function noted significant improvement in average knee score. However, between 10% and 47% of patients had significant knee pain at final follow-up. Total knee arthroplasty provides significant improvement in knee pain and function for patients with rheumatoid arthritis. However, the rates of postoperative pain vary widely.

Primary bone tumors of the hand are relatively rare. Different treatment options have been described in case reports. In this study, the authors present the diagnostic methods and treatment strategies that they used. The goal of this study is to present the oncologic and functional outcomes of surgical resection of primary malignant and aggressive benign metacarpal bone tumors. This retrospective study included 7 patients with primary malignant and aggressive benign bone tumors of the metacarpals who underwent surgical resection with or without metacarpal reconstruction between 2000 and 2017, with a minimum follow-up of 2 years. Clinical and radiologic evaluations were reviewed, and functional evaluation was performed with the Musculoskeletal Tumor Society scoring system. Seven patients (6 female; 1 male), with a mean age of 30.9±11.3 years, were included in the study. Six tumors were de novo, whereas 1 was recurrent. After resection, 5 patients had metacarpal reconstruction. Nonvascularized fibula was used for 3 patients, extracorporeal freezing of the metacarpal using liquid nitrogen was used for 1 patient, and metacarpal shift was used for 1 patient. Mean follow-up was 52.6±26.7 months. At the final follow-up, mean Musculoskeletal Tumor Society score was 27.4±1.6, and no local recurrence was documented. One patient had chest metastasis after 8 years of follow-up. The results show that surgical resection of primary malignant and aggressive benign tumors of the metacarpal bones can achieve satisfactory functional and oncologic outcomes. [

Women represent only 15.3% of all residents and fellows in the field of orthopedic surgery. The rate of increase of women in the field of orthopedics continues to lag behind all other surgical specialties. The purpose of this study was 2-fold: (1) to evaluate male/female representation in orthopedic specialty societies and (2) to examine the involvement of male/female orthopedic surgeons on committees, in leadership roles, at annual meetings, and in receipt of monetary awards. A 12-question, anonymous survey was distributed to the executive directors of all 23 orthopedic specialty societies. The survey included questions about the breakdown of male/female membership as well as male/female orthopedic surgeon participation in various functions of the society. Fourteen (60.9%) of 23 executive directors from orthopedic specialty societies responded to the survey. Seven (50.0%) of 14 survey respondents reported society membership of more than 1000. Six (42.9%) of 14 survey respondents reported male membership of more than 1000, while only the Ruth Jackson Orthopaedic Society reported female membership of more than 1000. Eleven (78.6%) of 14 survey respondents (eg, American Association of Hip and Knee Surgeons, American Orthopaedic Foot and Ankle Society, American Orthopaedic Society for Sports Medicine) reported having more than 10 men in leadership positions, whereas 13 (92.9%) of 14 respondents reported 10 or fewer women in leadership positions. Most orthopedic specialty societies have lower female than male membership, fewer women in leadership positions, and fewer monetary awards granted to women compared with men. This disparity was more evident in anatomic societies (eg, American Association of Hip & Knee Surgeons, American Orthopaedic Foot and Ankle Society) compared with general orthopedic societies (eg, Ruth Jackson Orthopaedic Society, Orthopaedic Research Society). Female orthopedic surgeons remain underrepresented in orthopedic specialty societies. [

Coronavirus disease 2019 (COVID-19) rapidly changed the landscape of health care, particularly in the New York City area. The elderly population is particularly vulnerable to both the novel coronavirus and the effects of a fracture. The goal of this study was to compare trends and outcomes of hip fracture patients during the pandemic. This was a retrospective chart review of hip fracture patients from a suburban academic hospital on Long Island, New York, who presented from March 1 to May 30, 2020. Patient COVID-19 status, demographics, and hospital outcome measures were recorded. Statistical analysis was performed using heteroscedastic
t
tests for quantitative variables and chi-square tests for qualitative variables. There were 82 patients in the 2020 cohort and 111 in the 2019 control group, representing a 29.9% decrease in cases. The 2020 cohort presented to the hospital an average of 2.77 days after injury compared with 1.15 days for the 2019 control group (
P
=.0976). Patients in the 2020 cohort were more likely to be discharged home than to rehabilitation (
P
<.0001) and tended to be discharged with oral anticoagulation (
P
=.0809). There was no increase in 1-, 3-, or 6-month complications or mortality. During the pandemic, fewer patients were admitted with hip fractures, and the time from injury to presentation doubled. Patients were significantly less likely to be discharged to rehabilitation and more were discharged with oral anticoagulants. Overall, there was no increase in complications, and these data indicate that the authors were successfully able to provide high-quality care to hip fracture patients during the pandemic. [
