A total of 135 specimens of Pagellus bellotti were randomly collected from artisanal boats in August 2018. Study of sex ratio, gonad maturity and size-structure of Pagellus bellottii is meagre in Sierra Leone, and forms the basis of the present study. The study will contribute to current knowledge and promote rational exploitation of the stock. Length and weight were measured using a fish measuring board (cm) and digital weight scale (g) respectively. Sex and gonad maturity were macroscopically assessed. Results showed dominant males (71.9%) and significant difference observed (1:2.6) and expected (1:1) female: male sex ratios (p <0.05). Only 11.9% and 11.1% of male and female gonads transcended to the developed stage (Stage IV). The length-frequency distribution for combined sex was unimodal (modal class, 17cm-20.9cm). Mean length and weight respectively were, 19.04±0.32cm and 98.85±5.08g for males and 17.43±0.54cm and 78.61±6.32g for females. Growth exponent (b) for male, female and combined sex was 2.809, 2.928 and 2.850 respectively and the correlation coefficient for all sex categories showed (r > 0.9). Indexes of condition were greater than 1.0 (K > 1) for all sex categories. Results portrayed a heterogeneous gender population of Pagelus bellottii and vast similarity in reproductive strategies by both sexes. The fish comprised of one size group and males may be growing larger than the females. Growth pattern was near-isometric for females and negative allometric for the males, and both sexes were in better condition (K >1.0). An annual study could provide further insight.

The present study aimed to investigate the potential of red kwao kreua and compare the effect between two MT dosage regimens in terms of inducing sex reversal, survival rate, feed conversion ratio and gain in weight on red, ghana and chitralada strains of Nile tilapia. Red kwao kreua, 100 g kg-1 , 200 g kg-1 and 300 g kg-1 , dried and pounded roots and 40 and 60 mg kg-1 MT were prepared and mixed per one kilogram fishmeal. Results revealed that MT treatments had a comparable effect in terms of male sex ratio, SR, FCR and GW and are statistically significant as compared to the control. Red kwao kreua treatments did not have significant difference with the control and with the MT treatments in some cases. However, a 72.2 + 25.5 % male sex ratio was obtained in treatment 3 of the chitralada strain. As to the effect of the treatments on the three strains it was observed that they generally have comparable effects.

Gonado-somatic index and fecundity are tools for measuring the sexual maturity and ability of animals to reproduce.  This study investigates the reproduction of Trichiurus lepturus. Specifically, this aimed to determine the sex ratio, the GSI, the relationship between fecundity and total length, fecundity and total weight, fecundity and ovary weight. The Descriptive Method of research was used.  Percentage and chi-square was utilized in determining the percentage of occurrence and sex ratio respectively.   Pearson r Product Moment Coefficient of Correlation was used to determine the relationships of the parameters. The study revealed that females outnumbered males and the sex ratio for different month showed significant difference.  Spawning season was observed to occur in November and December as revealed in its GSI values and it synchronized with the full and new moon phases.  Fecundity is positively correlated with body weight, body size, and ovary weight where ovary weight is observed to be the best index for fecundity.  The results of this study could be used further for formal stock assessment of cutlassfish fishery.

AbstractObjective: This study aims to determine the correlation between risk factors and erosive esophagitis development.Methods: We conducted a retrospective observational study on a consecutive series of 19.672 patients who underwent upper gastrointestinal endoscopy between 01.01.2011-31.12.2017. A total of 3005 patients, diagnosed with erosive esophagitis, were included in the present study and stratified according to Los Angeles classification.Results: During the studied period we found 3005 patients with erosive esophagitis, sex ratio male to female was 1.3/1, the most common forms of esophagitis being grade A and B: 74.54% patients with esophagitis grade A, 14.80% patients with grade B; 5.29% patients were with grade C and 5.35% patients with esophagitis grade D. In severe esophagitis the male predominance was more prevalent (249 males, 71 female), with a sex ratio 3.50/1. The correlation of male gender with severe esophagitis was highly statistically significant (p < 0.0001, OR 2.97; 95% CI 2.25-3.91). Hiatal hernia was diagnosed in 1171 patients, the presence of large hiatal hernias, being an important predictor, with statistical significance (p < 0.0001, OR 3.41; 95% CI 2.22-5.21), for severe esophagitis development. Incidence of Helicobacter pylori infection was 11.51%, in the entire study group, with no statistical significant difference between patients with mild or severe esophagitis (12.02% vs 7.18%).Conclusion: Erosive esophagitis is a frequent disease, the most common forms being grade A and B. Male gender and the presence of hiatal hernia are the most important risk factors for erosive esophagitis development, in our study group.

Abstract Background The clinical significance of indeterminate pulmonary nodules (IPN) in patients with resectable pancreatic adenocarcinoma (PDAC) is unknown. The rate of detection on IPN has risen due to enhanced staging investigations to determine resectability. IPNs detected on preoperative imaging represent a clinical dilemma and complicate decision-making. Currently, there are no recommendations on the management of IPN. This review provides a comprehensive overview of the current knowledge on the natural history of IPN detected among patients with resectable PDAC. Methods A systematic review based on a search in Medline and Embase databases was performed. All clinical studies evaluating the significance of IPN in patients with resectable PDAC were included. PRISMA guidelines were followed. Results Five studies met the inclusion criteria. The total patient population was 761. The prevalence of IPN reported ranged from 18 to 71%. The median follow-up duration was 17 months. The median overall survival was 19 months. Patients with pre-operative IPN which subsequently progressed to clinically recognizable pulmonary metastases, ranged from 1.5 to 16%. Four studies found that there was no significant difference in median overall survival in patients with or without IPNs. Conclusion This is a first review on the significance of IPN in patients with resectable PDAC. The preoperative presence of IPN does not demonstrate an association with overall survival after surgery. The identification of IPN is a significant finding however it should not preclude patients with resectable PDAC from undergoing curative resection.

Data suggest that adjuvant human papillomavirus (HPV)-vaccination in women treated for cervical HPV diseases reduces recurrent disease. This study investigates adjuvant HPV-vaccination and the rate of recurrence in women undergoing surgery for vulvar high-grade squamous intraepithelial lesions (HSIL). From January 2013 to April 2020, we enrolled 149 women in a prospective case-control study. The control group (NV-group) was treated by standard surgery alone, while the study group received adjuvant vaccination soon after surgery (V-group). A follow-up was performed by vulvoscopy and HPV test. Statistical analysis was performed by Fisher’s exact test. HSIL recurrence was observed in 24/76 (32%) patients in NV-group and in 8/42 patients (19%) of the vaccinated group. By analysing the recurrence rate related to the incident and reactivated latent HPV infection, we found a significant difference between (17/76) 22.3% in NV-group and (2/42) 4.8% in V-group (p = 0.01). A reduction of 78.5% in incident/reactivated HPV infections was demonstrated. Data results add to the current knowledge about the mechanism of post-surgical adjuvant HPV vaccination. Our prospective study is the first to document the vaccine clinical effectiveness in preventing “reactivation” of latent HPV infections. Quadrivalent HPV vaccine administered after the surgical treatment for vulvar HSIL appears to be useful in preventing recurrent disease.

Abstract The almond moth Cadra cautella (Walker), a key pest of storage facilities, is difficult to manage using synthetic chemicals. Pheromone-based management methods remain a high priority due to advantages over conventional management practices, which typically use insecticides. Cadra cautella females release a blend of pheromone including (Z, E)-9,12-tetradecadienyl acetate (ZETA) and (Z)-9-tetradecadien-1-yl acetate (ZTA). The effect of these components on mating of C. cautella and how response varies with the population density and sex ratio remain unknown. In this study, the mating status of C. cautella was studied inside mating cages under different ratios of ZETA and ZTA diluted in hexane and at different population sizes either with equal or unequal sex ratio. The lowest percentage of mated females (highest mating disruption [MD] effects), corresponding to roughly 12.5%, was produced by a 5:1 and 3.3:1 ratio of ZETA:ZTA. Populations with equal sex ratio showed the lowest percentage of mated females, at 20% and 12.5% under lower and higher density, respectively. The next lowest percentage of mated females was produced when the sex ratio was set to 1: 2 and 2:1 male:female, with just 25% and 22.5% of moths mated, respectively. This study shows that mating status of C. cautella is influenced by ZETA:ZTA ratio, sex ratio, and population size. This current knowledge would have useful implications for mating disruption programs.

Abstract Objectives The aim of this study is to investigate the current knowledge and attitude of deep caries removal method among dental students in Malaysia. Materials and Methods A total of 303 students (n = 303) responded to the online questionnaire. The first part of questionnaire was to evaluate the demographic data of the respondents and focused on the technique and management approach used for deep caries lesion. The second part investigated the preferred treatment used for deep caries based on the designated clinical case, while the third part assessed the factors that affected the decision on deep caries management. Statistical Analysis Independent t-test was used to compare difference between the two groups. Results Seventy four percent of the students have the knowledge of the different methods of caries removal, while 25.8% were only familiar with complete caries removal. The preferred method for deep caries removal in permanent teeth was partial caries removal (53%). For primary dentition, 45.6% of the students prefer to perform pulpotomy as compared with other techniques. There was no significant difference in caries removal method for permanent teeth between undergraduate year of study (p > 0.05), which was partial caries removal at 52.7 and 53.5%, respectively. For primary dentition, the preferred caries removal method was pulpotomy for year 4 (39.8%) and year 5 (52%) students. The popular material to restore deep caries was resin composite (42%) followed by glass ionomer cement (23.3%). Conclusions This study showed that partial caries removal was the preferred method despite partial understanding on the identification of the clinical indicators of the technique.

Background: The European Resuscitation Council (ERC) 2015 basic life support (BLS) guidelines introduced a simplified algorithm compared to the ERC 2010 BLS guidelines. This was intended to improve adherence to guidelines and retention of skills. This study aimed to compare the retention of BLS skills 3 months after training using the ERC 2010 or 2015 guidelines. Methods: This was an observational study including video recordings of laypersons being skill tested 3 months after participation in a standardized ERC BLS/AED course using either the ERC 2010 guidelines or the simplified ERC 2015 guidelines. The endpoints were 1) remembering the correct sequence of BLS/AED algorithm, 2) remembering the correct sequence of the BLS/AED algorithm and performing all skills correctly, 3) time to: emergency medical service (EMS) call, first compression, and shock delivery. Results: We analyzed videos of 133 laypersons skill tested 3 months after initial training; 64 trained using the 2010 guidelines (mean ±standard deviation (SD) age: 40 ±11 years, male sex: 19 (30%)) and 69 trained using the 2015 guidelines (age: 44 ±10 years, male sex: 36 (52%)). Participants in the 2015 guidelines group improved the retention of the BLS/AED algorithm compared to the 2010 guidelines group (29 (42%) vs. 10 (16%), relative risk (RR): 2.7 (95% confidence interval (CI): 1.4 - 5.1) P=0.001). Both BLS/AED algorithm and all skills were correctly performed by 13 (19%) vs. 3 (5%) (RR: 4.0 (95% CI: 1.2 - 13.5) P=0.01) in the 2015 and 2010 groups respectively. No significant difference was found in time to EMS call (difference: 3 sec (95% CI: -2 - 9 sec) P=0.27), time to first compression (difference: 4 sec, (95% CI: -3 - 10 sec) P=0.28), and time to first shock (difference: 4 sec (95% CI: -5 - 14 sec) P=0.33) between the groups. Conclusion: BLS/AED training using ERC 2015 guidelines was associated with better skill retention compared to training using ERC 2010 guidelines. There was no difference in time to EMS call, first compression, or shock delivery.

Pendahuluan. Hiperkoagulasi merupakan faktor yang mendasari tingginya mortalitas akibat kejadian tromboemboli vena pada pasien kanker. Kemoterapi merupakan salah satu faktor yang diduga berkontribusi terhadap status hiperkoagulasi pada pasien kanker. Studi ini bertujuan untuk mengevaluasi perubahan status koagulasi yang ditandai dengan kadar D-dimer pada pasien kanker yang menjalani kemoterapi.Metode. Studi ini merupakan studi kohort prospektif di Pusat Kanker Nasional Indonesia yang melibatkan pasien kanker yang sudah terkonfirmasi melalui pemeriksaan histopatologi, dan memulai kemoterapi pada periode Mei hingga Juli 2018. Perubahan status koagulasi dinilai melalui kadar D-dimer plasma. Kadar D-dimer diukur sebelum dan 7 hari setelah kemoterapi. Analisis statistik menggunakan uji t berpasangan untuk menilai kemaknaan perubahan kadar D-dimer plasma sebelum dan setelah kemoterapi.Hasil. Sejumlah 89 pasien memenuhi kriteria inklusi, yang mana 74,2% adalah perempuan dan hampir separuh dari keseluruhan subjek terdiagnosis kanker payudara (44,9%). Mayoritas subjek (69,6%) terdiagnosis pada stadium III atau IV. Sejumlah 12,4% dari subjek mendapatkan kemoterapi berbasis cisplatin. Terdapat perbedaan yang bermakna antara kadar D-dimer sebelum dan setelah kemoterapi (p = 0,05). Studi ini juga menemukan perbedaan bermakna kadar D-dimer sebelum dan sesudah kemoterapi pada pasien kanker stadium III (t(35) = 2,48, p = 0,02) dan stadium IV (t(25) = 2,14, p = 0,04). Tidak terdapat perbedaan bermakna antara kadar D-dimer sebelum dan setelah kemoterapi pada pasien stadium I dan II. Analisis lanjutan berdasarkan kelompok kemoterapi menunjukkan bahwa terdapat perubahan kadar D-dimer yang bermakna pada kelompok yang mendapatkan kemoterapi cisplatin (t(10) = 2,31, p = 0,04), namun tidak pada kelompok yang mendapat kemoterapi non-cisplatin (t(77) = 1,50, p = 0,14).Simpulan. Terdapat perbedaan bermakna status koagulasi yang ditandai dengan kadar D-dimer 7 hari pasca mendapatkan kemoterapi, khususnya pada pasien kanker stadium III atau IV dan mendapatkan kemoterapi berbasis cisplatin. Kata Kunci: Cisplatin, kanker, kemoterapi, status koagulasiChange of Coagulation Status in Solid Cancer Patients Undergoing Chemotherapy in Indonesia: A Prospective Cohort StudyIntroduction. Cancer-associated hypercoagulability was an underlying factor of high mortality of cancer due to venous thromboembolism. Chemotherapy is proposed as one of the contributing factors of the hypercoagulable state. We aim to evaluate the change of coagulation status, which was marked by D-dimer level, in cancer patients receiving chemotherapy.Methods. This is a prospective cohort study in Indonesian national cancer center which involves all adult histologically-confirmed-cancer patients who started chemotherapy between May and July 2018. The coagulation status is assessed by plasma of D-dimer level. We measured D-dimer before chemotherapy and one week after chemotherapy. Paired t-test was performed to assess the significant difference in D-dimer levels before and after chemotherapy.Results. A total of 89 patients fulfilled the eligibility criteria, of whom 74.2% were female and almost half of total subjects (44.9%) were breast cancer patients. Majority of subjects (69.6%) were stage III or stage IV cancer. There were 12.4% of subjects received cisplatin-based chemotherapy. There was a marginally significant difference in plasma level of D-dimers before and after chemotherapy (p = 0.05). We also found significant differences between D-dimer level before and after chemotherapy in stage III patients (t(35) = 2.48, p = 0.02) and stage IV patients (t(25) = 2.14, p = 0.04). There was no significant difference between D-dimer level before and after chemotherapy in stage I and stage II patients. Subgroup analyses based on chemotherapy agents showed that there was significant D-dimer change in cisplatin-based chemotherapy subjects (t(10) = 2.31, p = 0.04), but not in non-cisplatin-based chemotherapy subjects (t(77) = 1,50, p = 0.14).Conclusion. Compared to before chemotherapy, there is a significant difference of coagulation status marked by plasma D-dimer level one week after chemotherapy, particularly in patients with stage III or stage IV cancer and in patients receiving cisplatin-based chemotherapy.
