Abstract
Two new species of Parkellus (Jairajpuri et al., 2001) from Vietnam and a population of Parkellus zschokkei (Ahmad and Jairajpuri, 2010; Menzel, 1913) from Ukraine are described, illustrated and their phylogenetic position among the Mononchida is presented. The molecular data (18S and 28S rDNA) are given for the three investigated species – first time for the genus Parkellus. Parkellus hagiangensis sp. nov. is characterized by a medium-sized buccal cavity, posterior position of the dorsal tooth located below the beginning of the pharynx, males having the ventromedian cuticular pores above and below the excretory pore, short spicules with conical proximal part; females with very faint pars refringens vaginae and small teardrop-shaped pieces, short pars distalis vaginae, the presence of small ventromedian vulval papillae. Parkellus tuyenquangensis sp. nov. is characterized by a medium-sized buccal cavity, posterior position of the dorsal tooth located above the beginning of the pharynx, males having the ventromedian cuticular pores above and below the excretory pore, medium-sized spicules with a cylindrical proximal part, very short lateral guiding pieces, females with very strongly sclerotized pars refringens vaginae, medium size teardrop-shaped pieces, short pars distalis vaginae thickened at the junction with pars refringens vaginae. The newly described species are morphologically most similar to P. parkus and P. zschokkei. An identification key to Parkellus species is presented.
Modelling of time-varying meshing stiffness under tooth wear condition for nonlinear dynamics in compound planetary gear set
Authors: Yang Chao , Zhang Haibo 
Published: August 2021

Under tooth profile wear condition, with running time increasing, the tooth chord length of the gear tooth is thinner and the tooth profile is not involute profile any more, which results in the changes in amplitude and fluctuation of time-varying meshing stiffness. In this work, in order to reveal the influence of tooth profile wear on time-varying meshing stiffness, an analytical model for calculating the time-varying meshing stiffness under tooth wear condition is built and incorporated with a “translational-rotational” dynamic model of compound planetary gear set. Poincare section, the phase trajectory and bifurcation diagram are employed for analysis of periodic and chaotic motion. The results indicate that, tooth wear accumulation result in the reduction in the amplitude of meshing stiffness at the meshing region of double-pair teeth, but makes no difference in meshing stiffness for the meshing region of single-pair teeth. In order to avoid the system being in Chaos motions, under large tooth wear condition, the input speed should be avoided away from 3700 r/min-6725 r/min, so as to keep the system in a stable periodic motion state.
Modelling streamflow and sediment yield using Soil and Water Assessment Tool: a case study of Lidder watershed in Kashmir Himalayas, India
Authors: Gull Sarvat , Shah Shagoofta Rasool 
Published: August 2021

Abstract
The conjunction of heavy snowfall during winters and intensive rainfall during monsoons along with the mountainous topography expose the Lidder watershed to serious erosion and flood aggravation issues. Barely any attempts have been made for an in-depth examination of the Lidder watershed for precise estimation of sub-basin level runoff and erosion. In this study, the Soil and Water Assessment Tool (SWAT) was calibrated using the Sequential Uncertainty Fitting algorithm (SUFI-2) for modelling streamflow and sediment yield of the Lidder watershed. Daily runoff and sediment event data from 2003–2013 were used in this study; data from 2003–2008 was used for calibration and 2009–2013 for validation. Model performance was evaluated using various statistical tools, which showed good results revealing excellent potential of the SWAT model to simulate streamflow and sediment yield for both calibration and validation periods. The annual rate of average upland sediment drawn from the watershed was approximately 853.96 Mg/ha for an average surface runoff of 394.15 mm/year. This study identifies the vulnerable areas of the Lidder watershed, which can be thoroughly examined by decision-makers for effective management and planning. Further, the calibrated model can be applied to other watersheds with similar characterization to influence strategies in the management of watershed processes.

Published: August 2021

Abstract
Textile industries are among the primary contributors of water pollution. Treatment of textile wastewater is very important before discharging it to the environment. In the present study, laboratory-scale anaerobic batch reactors were used for co-treatment of a mixture of textile and domestic wastewater at 37 °C. The objective of this work was to investigate optimum conditions for the anaerobic co-digestion of textile wastewater and domestic wastewater. Domestic wastewater as a carbon source to enhance treatment of textile wastewater in color and other pollutants removal was examined. Textile and domestic wastewater were mixed at different proportions to make a total volume of 500 mL. Proportions of domestic wastewater and retention time were two main factors studied in influencing pollutant removal efficiency. Optimum conditions for removal of pollutants were 18 days' residence time at 60 and 40% textile and domestic wastewater respectively. The removal efficiencies were 52.8, 58.3 and 51.6% for Color, BOD and COD, respectively. Phosphorus (PO43−), Ammonium (NH3-N) and Nitrate (NO3-) increased at 78.5, 49 and 87% respectively. However, the concentration levels were above Tanzania Bureau of Standards (TBS) discharge limits. Post treatment is suggested to achieve standard discharge limits.

Authors: Shahbaz Sanaz Keshavarz , Koushki Khadijeh , Sathyapalan Thozhukat , Majeed Muhammed , Sahebkar Amirhossein 
Published: August 2021

:Progressive degeneration and dysfunction of the nervous system because of oxidative stress, aggregations of misfolded proteins, and neuroinflammation are the key pathological features of neurodegenerative diseases. Alzheimer's disease is a chronic neurodegenerative disorder driven by uncontrolled extracellular deposition of β-amyloid (Aβ) in the amyloid plaques and intracellular accumulation of hyperphosphorylated tau protein. Curcumin is a hydrophobic polyphenol with noticeable neuroprotective and anti-inflammatory effects that can cross the blood-brain barrier. Therefore, it is widely studied for the alleviation of inflammatory and neurological disorders. However, the clinical application of curcumin is limited due to its low aqueous solubility and bioavailability. Recently, nano-based curcumin delivery systems are developed to overcome these limitations effectively. This review article discusses the effects and potential mechanisms of curcumin-loaded PLGA nanoparticles in Alzheimer’s disease.

Authors: Matsumura Martin E. , Austin Kelly , Khalil Yasser , Blankenship James C. , Martin Bryan 
Published: August 2021

Introduction:
The COVID-19 (Coronavirus infectious disease 2019) pandemic has highlighted the need for alternative modalities to connect with outpatients beyond in-person clinic visits. In the present study, we evaluated the feasibility of a telephone-based teleconsultation cardiology service and compared the use of testing and outcomes between teleconsultation and traditional in-office consultations

Methods:
The study took place prior to the COVID-19 pandemic July 2019 to March 2020. Consult lists were reviewed by a cardiologist for patients appropriate for teleconsultation. Those patients were contacted directly and, if agreeable, a consultation was completed and any required testing was arranged. A series of patients seen in the clinic, matched for a reason for consultation and consulting a cardiologist, were compared in terms of testing frequency and outcomes.

Results:
Of 157 patients who felt appropriate for teleconsultation, 100 (63.7%) were successfully contacted and a teleconsultation was completed. Comparing patients undergoing teleconsultation with a matched series of patients seen in person in the clinic, there were no significant differences in testing utilization or outcomes, including emergency room or hospital admission within 30 days of consultation or death or adverse cardiac events at six months following consultation.

Conclusion:
Telemedicine can be successfully utilized as an alternative to traditional clinic consultation for selected patients needing cardiology consultation. This consultative modality does not appear to lead to utilization of increased testing or decreased quality or patient outcomes. Larger studies are needed to assess this mode of consultation.

Published: August 2021

Objective:
To evaluate the common dental emergencies reported to dental practitioners and to compare the mitigation strategies implemented during the Shelter-In-Place (SIP) warning with dental practitioners’ age and sex.

Methods:
We conducted a cross-sectional online survey among the dental practitioners of south India during the period of COVID-19 SIP warning. An initial pool of items was prepared to capture the mitigation strategies in managing local dental emergencies. A structured questionnaire was then prepared in English based on the inputs of four expert dentist panel. Age and sex of the practitioners were also recorded.

Results:
The mean age of the dental practitioners was 37.11(range: 23 - 63) years.Of 159 dental practitioners that responded to survey, 90 were male. Most dental practitioners responded that they were contacted through a phone call (n=140) and WhatsApp messaging (n=108). The common dental emergencies reported were tooth pain (100%), swelling (91.7%), a decayed tooth (81.3%), and gum pain (78.6%). A higher number of male than female dental practitioners had “scheduled the treatment immediately” (OR=3.45; P=0.002) after adjusting for age.

Conclusion:The most common dental emergencies during COVID-19 SIP were tooth pain, swelling, decayed teeth, and gum pain. Males and older dental practitioners scheduled appointments immediately.
A Qualitative Study on Challenges Chinese Nurses Face while Working in Japanese Hospitals
Authors: Tuo Jinmei , Kabayama Mai , Kamide Kei , Aimi Yoshinari 
Published: August 2021

Background: Considering the increased numbers of Chinese nurses in Japan, we hypothesized that Chinese nurses in Japan are confronted with many difficulties, although few studies have been performed. Therefore, in-depth analyses of their experience to explore significant factors and aspects are required.

Objectives: To clarify the problems and difficulties faced by Chinese nurses during their work and life in Japan and to address their future challenges.

Methods: We performed semi-structured interviews with 13 Chinese nurses working at 2 Japanese hospitals with Chinese and Japanese registered nurse licenses in 2017. We analyzed data using a qualitative inductive method.

Results: We found that Chinese nurses were motivated to work at Japanese hospitals for several reasons. Many Chinese nurses working in Japan had difficulties with the language barrier, interpersonal relationships related to cultural differences, and loneliness in their daily life, and also experienced fewer opportunities for promotion than Japanese nurses and insufficient support from Japanese hospitals. Many Chinese nurses were anxious about their future in Japan. More than half did not have a clear future direction for their working life in Japan.

Conclusion:
This study clarified the circumstances and difficulties of Chinese nurses working in Japan. One novel finding was that the main reason for their difficulties is due to their unknown career path and future workplace setting. Therefore, support for overcoming the language barrier and improving cultural understanding from hospitals is necessary to help nurses make better decisions based on their future plans.

Authors: Chupradit Priyanut W. , Chupradit Supat , Kumkun Chanakarn , Kumkronglek Jedbordin , Joompathong Natthanit 
Published: August 2021

Background:
Youth dormitory management in Thailand’s education system reveals evidence of discrimination. This is due to the high deviation in educational policy in aspects such as high cost or budget of educational management with dormitory provision in some programmes, when compared to the lower number of youth who receive the benefits of these programmes. Moreover, some programmes are not fair in the selection criteria and had the objectives that responded only to a specific group of population.

Objective:
The objectives of the study were to implement a group intervention programme in life skills development for youth in highland rural school dormitories of Omkoi District, Chiang Mai Province, Thailand.

Methods:
This study used a qualitative research method to recruit and select 30 participants. Semi-structured interviews with open-ended questions were used to collect data from the participants. The thematic analysis method was used for analysing the collected data.

Results:
The findings revealed three themes: 1. The result of analysing and synthesising the context, 2. the result of developing the model, and 3. the result of the life skills development activity programme for youth who lived in the school dormitories.

Conclusion:
Further studies would be required in order to compare the situation between rural and urban areas. Furthermore, youth life skills development programmes should be developed in the appropriate contexts. Moreover, the researcher must pay more attention to the society and culture of the target audience in order to achieve development that would be consistent with the area.

Authors: Noddin Katie , Bradley Dani , Wolfberg Adam 
Published: August 2021

Background
The COVID-19 pandemic has presented obstacles for providers and patients in the maternal health care setting, causing changes to many pregnant women’s birth plans, as well as abrupt changes in hospital labor and delivery policies and procedures. Few data exist on the effects of the COVID-19 pandemic on the maternal health care landscape at the national level in the United States.

Objective
The aim of this study is to assess the incidence of key obstetrics outcomes (preterm delivery, Cesarean sections, and home births) and length of hospital stay during the COVID-19 pandemic as compared to the 6 months prior.

Methods
We conducted a retrospective cohort study of women aged 18-44 years in the United States who delivered between October 1, 2019, and September 30, 2020, had singleton deliveries, and completed a birth report in the Ovia Pregnancy mobile app. Women were assigned to the prepandemic cohort if they delivered between October 2019 and March 2020, and the pandemic cohort if they delivered between April and September 2020. Gestational age at delivery, delivery method, delivery facility type, and length of hospital stay were compared.

Results
A total of 304,023 birth reports were collected, with 152,832 (50.26%) in the prepandemic cohort and 151,191 (49.73%) in the pandemic cohort. Compared to the prepandemic cohort, principal findings indicate a 5.67% decrease in preterm delivery rates in the pandemic cohort (P<.001; odds ratio [OR] 0.94, 95% CI 0.91-0.96), a 30.0% increase in home birth rates (P<.001; OR 1.3, 95% CI 1.23-1.4), and a 7.81% decrease in the average hospital length of stay postdelivery (mean 2.48 days, SD 1.35). There were no overall changes in Cesarean section rates between cohorts, but differences were observed between age, race, and ethnicity subgroups.

Conclusions
Results suggest a need for continuous monitoring of maternal health trends as the COVID-19 pandemic progresses and underline the important role of digital data collection, particularly during the pandemic.

Published: August 2021

Background
Kidney selling is a global phenomenon, with higher-income countries functioning as recipients and lower-income countries as donors, reflecting the gaps due to poverty and vulnerability. In recent years, an increasing number of residents in a village near the capital city of Nepal have been selling their kidneys; however, the factors embedded in the local social, cultural, political, and individual context driving kidney selling are poorly understood.

Objective
The aim of this study is to explore the drivers of kidney selling and its consequences in Hokse village in central Nepal, using ethnographic methods and multistakeholder consultations.

Methods
An ethnographic approach will be adopted along with in-depth interviews and key informant interviews among the residents and kidney sellers in the village. Relevant participants in the village will be selected purposively using a snowball approach. The number of participants will be predicated on the principles of data saturation. In addition, consultations with relevant stakeholders will be conducted at various levels, which will include authorities within and outside the village, and policymakers. All interviews will be conducted face to face, audio-recorded for transcription, and subjected to a thematic analysis.

Results
This study was approved by Mahidol University Central Institutional Review Board (MU-CIRB 2020/217.1808) in September 2020 and by Nepal Health Research Council (NHRC 716/2020 PhD) in January 2021. The fieldwork started in February 2021 and the data analysis was completed in September 2021.

Conclusions
This study is expected to provide insight into the reasons underlying the practice of kidney selling based on the example of Hokse village, along with the perspectives of multiple stakeholders.

Depression and Diabetes in Workers Across the Life Span: Addressing the Health of America’s Workforce—Behavioral Risk Factor Surveillance System, 2014–2018
Authors: Kaur Harpriya , Scholl Juliann C. , Owens-Gary Michelle 
Published: August 2021

OBJECTIVE
Diabetes affects nearly 12.2% of U.S. adults. Comorbid depressive symptoms among U.S. workers with diabetes are associated with increased unemployment and reduced work performance. This study examined the age-group–specific prevalence of depression among U.S. workers with self-reported diabetes and identified factors associated with depression.

METHODS
Data from the 2014–2018 Behavioral Risk Factor Surveillance System were used to examine the prevalence of depression among adult workers with diabetes in the United States. Relationships between depression prevalence and diabetes and demographic, physical, and behavioral risk factors were examined through bivariate and multivariable analyses. Age was categorized into four groups: 18–34, 35–54, 55–64, and ≥65 years.

RESULTS
The overall prevalence of self-reported depression among U.S. workers with diabetes was 17.4–30% higher than among those without diabetes. Workers with diabetes aged 18–34 years had the highest depression prevalence (28.7%) compared with other age-groups. Female workers with diabetes were significantly more likely than male workers to report depression in all age-groups. Young adult workers with diabetes who had another chronic disease were nearly three times more likely to report depression than those without another chronic condition. There were no overlapping patterns of prevalence of diabetes and depression by state.

CONCLUSION
Workers with diabetes are at an increased risk of depression, which can affect their overall health and productivity. These findings indicate that, among those with diabetes, young adult workers and women are most likely to have depression. Employee wellness programs may address the specific needs of individuals with diabetes and depression.
