Abstract
Introduction
Intestinal parasites are amongst the major public health challenges facing Sub-Saharan Africa. The aim of the study was to determine the prevalence of intestinal parasites and its associated factors among food handlers in Medebay Zana District, Tigray, Ethiopia.

Methods
A cross-sectional study was conducted among 401 food handler individuals selected by systematic random sampling. Binary and multivariable logistic regression was used to determine the possible association between the independent variable and outcome variables. Statistical significance was declared at p-value < 0.05 with a 95% confidence interval.

Result
The prevalence of intestinal parasites was 33.2% within this sample. The dominant parasite was Entamoeba coli 50(37.4%), followed by Entamoeba histolytica/dispar 24(18%), Entamoeba hartmanni 18(13.5), Giardia lamblia 17(12.8%), Schistosoma mansoni 8(6%), Hymenolepis nana 7(5.3%), Entervious vermicularies 6(4.5%) and Taenia species 3(2.5%).

Conclusion
This study revealed a high prevalence of intestinal parasites among food handlers for a range of intestinal parasites. The significant predictors were the source of water, washing hands before food preparation, washing hands with soap and water after visiting the toilet, shower installation at the workplace, washing the body regularly and eating raw vegetables and raw meat. Hence, local health planners should implement appropriate interventional measures for the novel risk factors to mitigate the problem.
COVID-19 in comparison with other emerging viral diseases: risk of geographic spread via travel
Authors: Wilder-Smith A. 
Published: January 2021

AbstractPurpose of reviewThe COVID-19 pandemic poses a major global health threat. The rapid spread was facilitated by air travel although rigorous travel bans and lockdowns were able to slow down the spread. How does COVID-19 compare with other emerging viral diseases of the past two decades?Recent findingsViral outbreaks differ in many ways, such as the individuals most at risk e.g. pregnant women for Zika and the elderly for COVID-19, their vectors of transmission, their fatality rate, and their transmissibility often measured as basic reproduction number. The risk of geographic spread via air travel differs significantly between emerging infectious diseases.SummaryCOVID-19 is not associated with the highest case fatality rate compared with other emerging viral diseases such as SARS and Ebola, but the combination of a high reproduction number, superspreading events and a globally immunologically naïve population has led to the highest global number of deaths in the past 20 decade compared to any other pandemic.

Abstract
Background
Cancer therapy-related cardiac dysfunction (CTRD) is a major source of morbidity and mortality in long-term cancer survivors. Decreased GLS predicts decreased left ventricular ejection fraction (LVEF) in patients receiving anthracyclines, but knowledge regarding the clinical utility of baseline GLS in patients at low-risk of (CTRD) is limited.

Objectives
The purpose of this study was to investigate whether baseline echocardiographic assessment of global longitudinal strain (GLS) before treatment with anthracyclines is predictive of (CTRD) in a broad cohort of patients with normal baseline LVEF.

Methods
Study participants comprised 188 patients at a single institution who underwent baseline 2-dimensional (2D) speckle-tracking echocardiography before treatment with anthracyclines and at least one follow-up echocardiogram 3 months after chemotherapy initiation. Patients with a baseline LVEF <55% were excluded from the analysis. The primary endpoint, (CTRD), was defined as an absolute decline in LVEF > 10% from baseline and an overall reduced LVEF <50%. Potential and known risk factors were evaluated using univariable and multivariable Cox proportional hazards regression analysis.

Results
Twenty-three patients (12.23%) developed (CTRD). Among patients with (CTRD), the mean GLS was -17.51% ± 2.77%. The optimal cutoff point for (CTRD) was -18.05%. The sensitivity was 0.70 and specificity was 0.70. The area under ROC curve was 0.70. After adjustment for cardiovascular and cancer therapy related risk factors, GLS or decreased baseline GLS ≥-18% was predictive of (CTRD) (adjusted hazards ratio 1.17, 95% confidence interval 1.00, 1.36; p = 0.044 for GLS, or hazards ratio 3.54; 95% confidence interval 1.34, 9.35; p = 0.011 for decreased GLS), along with history of tobacco use, pre-chemotherapy systolic blood pressure, and cumulative anthracycline dose.

Conclusions
Baseline GLS or decreased baseline GLS was predictive of (CTRD) before anthracycline treatment in a cohort of cancer patients with a normal baseline LVEF. This data supports the implementation of strain-protocol echocardiography in cardio-oncology practice for identifying and monitoring patients who are at elevated risk of (CTRD).

Abstract
Background
Little is known about complications after major duodenopancreatic surgery for duodenopancreatic neuroendocrine tumors (dpNETs) in multiple endocrine neoplasia type 1 (MEN1). Therefore, the incidence and severity of complications after major surgery for MEN1-related dpNETs were assessed.

Methods
Patients were selected from the population-based Dutch MEN1 database if they had undergone a Whipple procedure or total pancreatectomy from 2003 to 2017. Complications were graded according to the Clavien–Dindo classification (grade III or higher complications were considered a severe complication) and definitions from the International Study Group of Pancreatic Surgery. The Cumulative Complication Index (CCI®) was calculated as the sum of all complications weighted for their severity. Univariable logistic regression was performed to assess potential associations between predictor candidates and a severe complication.

Results
Twenty-seven patients (median age 43 years) underwent a major duodenopancreatic resection, including 14 Whipple procedures and 13 total pancreatectomies. Morbidity and mortality were 100% (27/27) and 4% (1/27), respectively. A severe complication occurred in 17/27 (63%) patients. The median CCI® was 47.8 [range 8.7–100]. Grade B/C pancreatic fistulas, delayed gastric emptying, bile leakage, hemorrhage, and chyle leakage occurred in 7/14 (50%), 10/27 (37%), 1/27 (4%), 7/27 (26%), 3/27 (11%) patients, respectively. Patients with a severe complication had longer operative time and higher blood loss. After Whipple, new-onset endocrine and exocrine insufficiency occurred in 1/13 and 9/14 patients, respectively.

Conclusions
Major duodenopancreatic surgery in MEN1 is associated with a very high risk of severe complications and cumulative burden of complications and should therefore be reserved for a select subgroup of patients with MEN1-related dpNETs.

Abstract. Asrial E, Marzuki M, Hamid, Khasanah RI. 2021. Sustainability analysis of tomato jellyfish (Crambione mastigophora) fisheries resources management in Saleh Bay Waters, Sumbawa Island, Indonesia. Biodiversitas 22: 512-520. The tomato jellyfish (Crambione mastigophora) or gullung (local term), is endemic in Saleh Bay, Sumbawa Island, Indonesia and has been utilized as an additional livelihood by fishermen for last two decades. Its commonly caught by 2-4 fishermen/boat using scoop net, wooden fishing vessels, and lamps as attractors and collectors of jellyfish. This study aims to determine the sustainability of jellyfish fisheries management. A survey-dependent method with sampling, observation, dialogue, and documentation techniques was applied for data compilation. The rapid appraisal for jellyfish fisheries - six dimensions (Rapjellyfish-6D), based on Rapfish technique, is utilized for analysis of the sustainability status of jellyfish fisheries management. This paper describes the sustainability analysis results for two of the six dimensions of jellyfish fisheries management, namely the technological dimension (13 attributes) as an input factor and the economic dimension as an output factor (14 attributes). At present, around 8-30 baskets/boat/day of jellyfish mouth-arms are being sold to the buyers in Saleh Bay. This catch's profit is divided between the fishermen (3 parts) and the boat owner (2 parts). The analytical results show the revenue per cost ratio (R/C Ratio) as 4.75 which means that every 1.00 Indonesian Rupiah (IDR) the cost of catching jellyfish will generate IDR 4.75. The breakeven point (BEP)Price is IDR 13,158 and BEPProduction is 3.13 and 8.33 baskets/trip for the assumed price of IDR 80,000 and IDR 30,000. The technological (36.13%) sustainability status and economic (49.64%) dimension is Less Sustainable. The leverage analysis results indicate that the group of sensitive attributes in the technological and economic dimensions, respectively, consists of 5 attributes and 3 attributes. All sensitive attributes have an impact on the low value of management sustainability. The sustainability of jellyfish fisheries management in Saleh Bay has been supported by a choice of environmentally friendly fishing methods. Besides, the mouth-arm price is formed from an oligopsony market system that is not profitable for fishermen. It is suggested to the village government to build an integrated and environmentally friendly scyphozoan facility to neutralize the liquid waste generated from scyphozoan processing.

Abstract. Fadhilah QG, Santoso I, Yasman. 2021. The antagonistic activity of marine actinomycetes from mangrove ecosystem against phytopathogenic fungi Colletotrichum sp. KA. Biodiversitas 22: 642-649. Marine actinomycetes from mangrove ecosystems are known to be potential antifungal-producing isolates against phytopathogenic fungi. The aim of this research was to obtain potential marine actinomycetes isolates against the phytopathogenic fungi Colletotrichum sp. KA. Screening of 15 marine actinomycetes isolates using a dual culture method with a plug technique showed that 80% of isolates have antagonistic activity, represented as a percentage of growth inhibition range from 47.96% to 84.94%. Among 12 potential isolates, six isolates (SM4, SM11, SM14, SM15, SM18, and SM20) were evaluated for delayed antagonistic activity with incubation periods of 6, 9, and 12 days using the plug and streak techniques. The results showed that the percentage of growth inhibition of selected isolates inclined to increase along with the incubation period prior to inoculation of Colletotrichum sp. KA. Delayed antagonist assays using the streak technique resulted in higher inhibition results compared to the plug technique. Furthermore, the non-delayed assays of the two selected isolates, SM11 and SM15, also inhibited Colletotrichum sp. KA 57.99% and 59.88%, respectively. The delayed antagonist assay with a shorter incubation period of the two selected isolates also showed an increased percentage of growth inhibition of Colletotrichum sp. KA. According to our research, the delayed antagonistic assay of marine actinomycetes isolates with a 12-day incubation period using a plug technique was representative to evaluate the percentage of growth inhibition.

Abstract. Hadi MS, Abadi AL, Himawan T, MAsruri, Lestari SR, Rahardjo BT, Aini LQ, Setiawan Y, Tarno H. 2021. The role of bacterial symbionts in the biodegradation of chlorpyrifos in the digestive tract of Plutella xylostella larvae. Biodiversitas 22: 702-712. Several species in the order Lepidoptera act as plant pests, one of which is Plutella xylostella. Plutella xylostella is one of the most destructive pests of cabbage and other horticultural crops. The use of chemical insecticides as pest control for P. xylostella causes many problems, such as the increased pest resistance to pesticides. The objectives of this study are: (i) to obtain and characterize symbiont bacteria in the digestive tract of P. xylostella collected from organic and conventional agriculture soils; (ii) to evaluate the potential of bacterial symbionts in the digestive tract of P. xylostella from organic and conventional soils in degrading the active ingredient of chlorpyrifos insecticide; (iii) To determine the biodegradation process of chlorpyrifos insecticide by symbiont bacteria in the digestive tract of P. xylostella; and (iv) to identify the derivative compounds from the biodegradation of chlorpyrifos insecticide. The results showed 30 symbiont bacteria isolated from the digestive tract of P. xylostella collected from organic soil and 36 symbiont bacteria isolated from the digestive tract of P. xylostella from conventional farming soil. There are 15 species of symbiont bacteria in 5 genera from the digestive tract of P. xylostella from organic and conventional farming capable of degrading the chlorpyrifos insecticide. They are identified as Providencia sp., Pseudomonas sp., Serratia sp., Proteus sp., and Aeromonas sp. Chlorpyrifos-derived compounds from the biodegradation of symbiont bacteria are less toxic than chlorpyrifos compounds.

Abstract. Mansouri NJS, Akbarzadeh K, Jahanifard E, Vazirianzadeh B, Rafinejad J. 2021. Species diversity and abundance of scorpions in Ahvaz city, Southwest Iran. Biodiversitas 22: 763-768. Arthropods are one of the most important and diverse phyla of the animal kingdom. This phylum includes several classes of insects and arachnids, which are of medical and veterinary importance. Scorpions are at the top of the group of venomous arthropods in terms of having venomous bites and causing death. Scorpions live mainly in tropical and subtropical regions of the world and therefore have higher diversity and richness in these regions. This study aimed to investigate the biodiversity and abundance of scorpions in Ahvaz city, Khuzestan province, Iran. It has the highest species diversity and species richness in Iranian scorpions. Scorpions were collected from five regions in Ahvaz using various methods. In total 237 scorpions were collected and identified. They belonged to two families, seven genera and seven species: Mesobuthus eupeus (65%), Hemiscorpius lepturus (23.2%), Androctonus crassicauda (3.8%), Compsobuthus rugosulus (3.4%), Orthochirus zagrosensis (2.5%), Apistobuthus susanae (1.7%), Buthacus macrocentrus (0.4%). Except for H. lepturus (Hemiscorpiidae), other species belonged to the Buthidae family. That all of them were non-burrowing. M. eupeus was the dominant species diversity analysis indicated higher species richness and species diversity for summer (Margalef = 1.07; Shannon = 1.55). Logistic regression analysis showed that the variables of geographical location, humidity, and temperature had a significant relationship with the abundance of scorpion species, while height had no statistically significant.

Abstract. Habsyah TS, Basyuni M, Siregar LAM, Afandi D, Syahputra I. 2021. Distribution of polyprenol and dolichol in oil palm genotype (Elaeis guineensis) involving lipase activity. Biodiversitas 22: 830-837. The aim of this study was to determine the pattern of chemical compounds from the polyisoprenoid group in oil palm plants that were contributing to the lipase activity. The study was conducted in two locations. A sampling of leaves and fruit mesocarp from 90 progenies was conducted at PT. Socfin Indonesia Aek Loba Plantation, Asahan District, North Sumatra, Indonesia. Biochemical analysis of polyisoprenoid was carried out at the Forest Biotechnology Laboratory, Faculty of Forestry, University of Sumatera Utara, Medan. The results showed that the total lipids in leaves tissue ranged from 0.40 to 1.032 mg/g, with the lowest total lipid found in SL-4966 progeny and the highest total lipid found in SL-9737 progeny. Polyisoprenoid values ​​ranged from 1.63 to 10.82 mg/g dry weight. The highest polyisoprenoid content was obtained in SL-10682 progeny, and the lowest was in SL-5045 progeny leaf tissue. The polyisoprenoid ​​in fruit mesocarp tissue ranged from 1.79 to 4.14 mg/g. The lowest polyisoprenoid content (1.79 mg/g) of fruit mesocarp was found in SL-4233 progeny, while the highest (4.14 mg/g) was found in SL-5010 progeny. Dolichol and polyprenol are equally dominant in palm leaves. Carbon polyprenol chain lengths ranged from C45-C105, and dolichol ranged from C50-C110. The polyprenol carbon chain lengths in the mesocarp tissues were C65-C120 and dolichol was C65-C125. Polyisoprenoid analysis on oil palm leaf and fruit mesocarp tissue showed that lipid patterns of oil palm leaf and mesocarp were categorized as type II lipid patterns. It provides important information for selecting genotypes of low lipase activity of oil palm plants.

Abstract. Mohamadi Y, Lograda T, Ramdani M, Figueredo G, Chalard P. 2021. Chemical composition and antimicrobial activity of Myrtus communis essential oils from Algeria. Biodiversitas 22: 933-946. The objectives of this study were to determine the chemical composition and the antibacterial activities of Myrtus communis essential oils. The aerial parts of the myrtle were collected from nineteen localities of the Algerian coast, and subjected to hydrodistillation. The chemical composition of essential oils was analyzed using gas chromatography coupled with mass spectrometry (GC/MS). The antibacterial activity was evaluated by the disk diffusion method against ten bacterial species. Essential oils of M. communis was pale yellow oils, very fragrant, with an average yield of 0.68 ± 0.6%. Forty-six compounds were identified, representing an average of 99.17 ± 0.6% of total oils. The α-pinene was the most abundant component in the essential oils of all populations studied, with a mean of 50.1 ± 10.3%, followed by 1,8-cineole (22.27 ± 4.32%), limonene (5.16 ± 2.67%), linalool (3.79 ± 2.97%), α-terpineol (2.75 ± 1.12%), geranyl acetate (1.95 ± 0.7%) and methyl eugenol (1.40 ± 0.98%). Myrtenyl acetate was only observed in four populations with significant levels (from 10.66 to 20.94%). Six chemotypes have been identified in these oils. The α-pinene – 1,8-cineole - limonene chemotype was found in the majority of populations. The chemotype of α-pinene - 1,8-cineole - α-terphenyl acetate characterizes the Oued El-Aneb population. The α-pinene - neryl formate - limonene chemotype is observed in the Honaïn population. The remaining populations are characterized by myrtenyl acetate. The essential oils of M. communis were effective against Staphylococcus aureus ATCC 25923, Salmonella enterica ATCC35659, Proteus mirabilis, and Escherichia coli ATCC 25922; however, no significant effect was observed on Klebsiella pneumonia ATCC 700603 and Serratia liquefaciens.
