Usaha perikanan tangkap merupakan salah satu mata pencaharian nelayan yang mulai berkembang di era new normal. Penelitian ini bertujuan untuk menganalisis aspek-aspek yang mempengaruhi usaha perikanan tangkap di Daerah Bondet di era new normal pasca pandemi Covid-19. Metode yang digunakan adalah metode survei terhadap faktor-faktor yang mempengaruhi masyarakat nelayan di sekitar Pelabuhan Perikanan Pantai Bondet. Data diperoleh melalui kegiatan wawancara kepada nelayan pemilik kapal kemudian dianalisis menggunakan metode deskriptif kualitatif. Berdasarkan hasil penelitian diketahui bahwa faktor-faktor yang mempengaruhi usaha perikanan tangkap dapat dilihat melalui lima faktor yaitu faktor teknis, faktor produktivitas, faktor pemasaran, faktor sosial dan finansial. Berdasarkan analisis faktor teknis, unit penangkapan ikan yang ada di perairan Bondet terdiri dari kapal motor (5-10 GT) dan perahu motor tempel (<5 GT), produktivitas kapal motor lebih besar dibandingkan perahu motor tempel. Pola pemasaran hasil perikanan masih belum optimal karena belum ditunjang sarana dan prasarana yang memadai. Hasil analisis finansial, kapal motor memperoleh keuntungan sebesar Rp 73.399.560 per tahun, R/C 5,92  dan PP 2,44. Perahu motor tempel memperoleh keuntungan sebesar  Rp 33.658.200 per tahun, R/C 5.29 dan PP 2,67.
 
Bondet Village is a potential area in the development of capture fisheries on the North Coast of West Java. Capture fisheries business is one of the livelihoods of fishermen who are starting to develop in the new normal era. This study aims to analyze the aspects that affect the capture fisheries business in the Bondet area in the new normal era after the Covid-19 pandemic. The method used is a survey method to the factors that affect the fishing community around the Bondet Beach Fishing Port. The data was obtained through interviews with fishermen who own boats and then analyzed using qualitative descriptive methods. Based on the research results, it is known that the factors that influence the capture fisheries business can be seen through five factors, namely technical factors, productivity factors, marketing factors, social and financial factors. Based on the analysis of technical factors, fishing units in Bondet waters consist of motor boats (5-10 GT) and outboard motor boats (<5 GT), the productivity of motor boats is greater than outboard motor boats. The marketing pattern of fishery products is still not optimal because it has not been supported by adequate facilities and infrastructure. The results of financial analysis, motor boats earn a profit of Rp. 73,399,560 per year, R/C 5.92 and PP 2.44. Outboard motor boats earn a profit of Rp 33,658,200 per year, R/C 5.29 and PP 2.67.

Authors: Spurgas Morgan P , Shao Miriam M , Entezami Pouya , German John W
Published: August 2022

Objective: Spinal fractures often have devastating sequelae. Thoracolumbar fractures are classified using the Thoracolumbar Injury Classification and Severity score (TLICS) to determine the severity of injury and to guide treatment. Recently advancements in minimally invasive spine surgery (MISS) have led to new approaches to high-severity fractures. Studies have suggested that MISS may yield similar outcomes to conventional, more invasive procedures while producing several benefits.Methods: This retrospective study involves 46 patients treated from 2005 through 2020 for high grade thoracolumbar trauma from T2 to L5 with a minimum follow-up of 6-months treated with MISS techniques using percutaneous instrumentation. Results: Average TLICS was 7.5. Patient derived outcome measures with average length of follow-up of 602 days included Oswestry Disability Index 28.9, Patient Satisfaction Index 4.2, Short Form-12 Mental Component Score 51.9, and Short Form-12 Physical Component Score 37.7. Average estimated blood loss was 119.2 mL.Conclusion: The TLICS is a validated tool used to guide surgical intervention in high grade trauma. The utilization of MISS techniques for the treatment and stabilization of thoracolumbar trauma is efficacious and a viable alternative to traditional open approaches.

Published: August 2022

Purpose
African American (AA) men are diagnosed with Prostate cancer (PCa) approximately 3 years younger, more often in an advanced stage, and incurable, when compared to Caucasian American (CA) men. We seek to study whether this difference is due to factors related to, stress, lack of knowledge of prostate cancer, race, or the combination of all these factors.
Methods
A questionnaire was administered to 389 participants (234 CA and 135 AA men) for a possible diagnosis of prostate cancer over 3 years. Quantitative data was collected from patients on demographic status along with their level of knowledge of prostate cancer and anxiety related to their diagnosis and possible treatment. Exact Pearson chi-square tests were used to test the independence between race and various socio-economic factors.
Results
In this study, for the first time, we investigated whether knowledge of the disease and anxiety following diagnosis and treatment could play a role in the disparity of prostate cancer among AA and CA men. We also confirmed that financial disparities among AA and CA men, with AA having more financial strain.
Conclusion
Our study showed that lack of knowledge of PCa screening and early detection, and lack of understanding of the diagnosis in combination with increased anxiety among AA patients, can play a role in PCa disparity.

Background:This study aimed to evaluate mortality risk associated with readily accessible laboratory parameters and underlying conditions in hospitalized older adults.Methods:This retrospective study included geriatric patients admitted for inpatient care to the internal medicine wards of two major university hospitals in two different regions of Turkey. Data related to the patients were collected by retrospective review of patient charts and electronic records. Survival data were obtained from the Death Reporting System of the Turkish Ministry of Health. Survival after admission at 30 days and 1 year was noted.Results:The study included 1,465 hospitalized older adults with a median age of 74 years, of whom (51.0%) were women. Of these patients, 115 (7.8%) died within 30 days and 382 (26.1%) died within 12 months. Admission for infectious diseases or palliative support and the presence of malignancy were identified as independent risk factors for both 30-day and 12-month mortality. A 1-unit increase in CCI corresponded to 20% higher odds of both 30-day and 12-month mortality. A 1-unit increase in MPV was associated with 52.5% higher odds of 30-day mortality. A 1-unit increase in CRP was associated with a small but statistically significant 0.6% increase in the odds of 30-day and 12-month mortality.Conclusions:The results of this study show that CCI, CRP, and NLR were associated with higher mortality both at 30 days and 12 months. A 1-unit increase in MPV was associated with 52.5% higher odds of 30-day mortality
A comparison of CT derived body composition at thoracic T4, T12 with lumbar L3 vertebral levels in patients with rectal cancer – which one should we utilise?

Published: August 2022

Background:Computed tomography (CT) derived body composition measurements of sarcopenia are an emerging form of prognostication in many disease processes. Outcomes in advanced rectal cancer treatment are typically dependent on success of using a combination of chemotherapy and surgery. There is growing evidence that body composition determines chemotherapy tolerance and surgical outcomes. Although the L3 vertebral level is commonly used to measure skeletal muscle mass, other studies have suggested the utilisation of other segments may also be appropriate. This study was performed to determine the variation and reproducibility in assessment of skeletal muscle mass at vertebral levels T4, T12 and L3 in pre-operative rectal cancer patients. Research Methods:118 adult patients with stage I – III rectal cancer, undergoing curative resection from 2010 – 2014, were assessed. CT based quantification of skeletal muscle was used to determine skeletal muscle cross sectional area (CSA) and skeletal muscle index (SMI). Agreement between the measurements at L3 with T4 and T12 vertebral levels were evaluated using goodness-of-fit, Pearson’s correlation coefficient, and Bland-Altman plots.Results:80 of 118 patients were included in our study. There were 21 (26%) female and 59 (74%) male patients (30-86years, Mean±SD; 63.0 ± 13.0). The correlation between SMI at L3 and SMI at T12 was stronger (r = 0.84, P < .001) than that between SMI at L3 and SMI at T4 (r = 0.80, P < .001). Intraclass correlation coefficient was >0.96 at all levels with agreement being highest at T12 and L3. Conclusions:This study demonstrated that quantifying skeletal muscle mass at the T12 vertebral level is straightforward, reproducible, reliable and comparable to measures achieved at L3 in patients with rectal cancer.
An adaptive bonnet polishing approach based on dual-mode contact depth TIFs

Published: August 2022

The industrial robot bonnet polishing platform can not only meet the requirements of high efficiency and precision of optical polishing, but also reduce the system cost. It is a promising polishing equipment solution. The most practical method to improve BP material removal efficiency is to increase the contact depth. It is generally believed that the profile of the TIF of BP is Gaussian like distribution traditionally, but it is found that it actually changes into M-shape obviously with large contact depth. However, the existing reports on the TIF of bonnet polishing are mostly based on the Gaussian like TIF model which cannot accurately describe the M-shaped TIF. Therefore, according to the material characteristics of inflatable rubber bonnet, this paper establishes a new model to explain the changes of pressure distribution caused by large contact depth. Furthermore, a bonnet polishing approach based on dual- mode contact depth TIFs is proposed in order to improve the removal efficiency in rough polishing stage and increase the convergence accuracy in fine polishing stage.

Published: August 2022

Objective: The Veterans Health Administration (VHA), the largest single provider of spinal cord injury and disorder (SCI/D) care in the nation, currently mandates that every patient receives a screening urinalysis and urine culture during the annual evaluation. This testing has shown in a small subset of patients to overidentify asymptomatic bacteriuria that is then inappropriately treated with antibiotics. The objective of the current analysis was to assess the impact of the annual evaluation on urine testing and antibiotic treatment and unnecessary prescribing in a national sample of Veterans with SCI/D. Design/Method: A retrospective cohort study using national VHA electronic health record data of Veterans with SCI/D seen October 1, 2017-September 30, 2018 (fiscal year (FY) 2018) for their annual evaluation.Results: There were 9447 Veterans with SCI/D who received an AE in FY2018; 5088 (54%) had a urine culture obtained. 2910 cultures (57%) were positive; E. coli was the most common organism obtained (12.9% of total urine cultures). Of the patients with positive urine cultures, 386 were prescribed antibiotics within the 7 days after that encounter (13%); of the patients with negative cultures (n=2178), 121 (6%) were prescribed antibiotics; thus, a positive urine culture was a significant driver of antibiotic use (p <0.001 ). Conclusion: The urine cultures ordered at the annual exam are often followed by antibiotics; this practice may be an important target for antibiotic stewardship programs in SCI.

The assessment of physical capacity will be performed before the physical Page 2 of 17 exercise programs interruption (T0- initial assessment-March/2020), pre-intervention (T1- immediately after the exercise program return) and post intervention (T2). The assessments of physical activity level, quality of life, mental health, functionality and body composition will be performed in T1 and T2.Discussion: The results from this MC+SM protocol will allow to contribute with clinical support to evaluate the variables analyzed, and to guide future public health policies, aiming at minimizing the possible deleterious effects arising from the physical exercise interruption periods caused by epidemics and pandemicsTrial registration: Prospectively registered.Registry Name: Use of self-management strategies combined with multicomponent training to mitigate the effects of social distance from COVID-19 on capacity, physical capacity, mental health and quality of life in the older adults - A blind, randomized and controlled clinical trial.Registration Number: RBR-10zs97gkDate of Registration: 17Jun2021URL: https://ensaiosclinicos.gov.br/rg/RBR-10zs97gk
Size Frequency Distributions, Fracture Patterns, and Reactive Surface Area of Shock Wave Lithotripsy-Derived Particles: A GeoBioMed Perspective on Kidney Stone Recurrence

Published: August 2022

Shock wave lithotripsy (SWL) is an effective and commonly applied clinical treatment for human kidney stones. Yet the success of SWL is counterbalanced by the risk of retained fragments causing recurrent stone formation, which may require retreatment. This study has applied GeoBioMed experimental and analytical approaches to determine the size frequency distribution, fracture patterns, and reactive surface area of SWL-derived particles within the context of their original crystal growth structure (crystalline architecture) as revealed by confocal autofluorescence (CAF) and super-resolution autofluorescence (SRAF) microscopy. Multiple calcium oxalate (CaOx) stones were removed from a Mayo Clinic patient using standard percutaneous nephrolithotomy (PCNL) and shock pulse lithotripsy (SPL). This produced approximately 4-12mm-diameter PCNL-derived fragments that were experimentally treated ex vivo with SWL to form hundreds of smaller particles. Fractures propagated through the crystalline architecture of PCNL-derived fragments in a variety of geometric orientations to form rectangular, pointed, concentrically spalled, and irregular SWL-derived particles. Size frequency distributions ranged from fine silt (4-8mm) to very fine pebbles (2-4mm), according to the Wentworth grain size scale, with a mean size of fine sand (125-250mm). Importantly, these SWL-derived particles are smaller than the 3-4mm-diameter detection limit of clinical microcomputed tomography (micro-CT) techniques and can be retained on internal kidney membrane surfaces. This creates clinically undetectable crystallization seed points with extremely high reactive surface areas, which dramatically enhance the multiple events of crystallization and dissolution (diagenetic phase transitions) that may lead to the high rates of CaOx kidney stone recurrence after SWL treatment.
Double-check in lizard age estimation: use of phalanx bone and keratin claw sheath lamellas
Authors: Galoyan Eduard , Sopilko Natalia , Kovalyeva Anna , Chamkina Anna
Published: August 2022

Background
Age estimation in vertebrates has always been a tricky and dubious procedure. The method of skeletochronology is commonly used for age estimation in poikilothermic and in some homoiothermic animals. This method is based on counting arrested growth lines (LAGs) within bone structures (tubule bones or teeth) in modern living or fossil animals. However, it fails to reveal the age with necessary precision due to hibernation and aestivation periods, hence, some referent method of age estimation is required for evaluating better precision. During the previous studies of population age structure in several species of rock lizards (Darevskia) we prepared microscope slides of finger bones and noticed presence of well-distinguished cornified unguis lamellas of the finger claws. We put forward that the number of these lamellas coincides with the number of LAGs in the periosteum bone of the same finger. To test this hypothesis, we performed special study and compared number of LAGs within each finger bone and cornified claw using traditional skeletochronological technique.
Results
The conducted analysis revealed positive correlation (rs=0.933, p < 0.001) and no significant differences between the number of LAGs in the bone and unguis lamellas of the same fingers of three species of Palearctic rock lizards (Darevskia portschinskii, D. raddei, D. valentini). We found no distinguished cornified lamellas in the claw of the tropical skink Sphenomoprhus maculatus.
Conclusion
We assume that the proposed method may be an efficient and reliable means of ecological studies based on toe-clipping and vital age estimation in lizards and, possibly, other poikilothermic vertebrates, as a double-check method based on two independent registration structures present potentially preventing possible mistakes in age estimation.

In the present work, we prepared MgO-La2O3-mixed-metal oxides (MMO) as efficient photocatalysts for degradation of organic pollutants. First, a series of MgAl-%La-CO3 layered double hydroxide (LDH) precursors with different content of La (5, 10 and 20 wt%) were synthesized by the co-precipitation process and then calcined at 600°C. The prepared materials were characterized by XRD, SEM-EDX, FTIR, TGA, ICP and UV–vis diffuse reflectance spectroscopy. XRD indicated that MgO, La2O3 and MgAl2O4 phases were found to coexist in the calcined materials. Also, XRD confirms the orthorhombic-tetragonal phases of MgO-La2O3. The samples exhibited a small band gap of 3.0-3.22 eV based on DRS. The photocatalytic activity of the catalysts was assessed for the degradation of two dyes namely Tartrazine (TZ) and Patent Blue (PB) as model organic pollutants in aqueous mediums under UV-Visible light. Detailed photocatalytic tests that focused on the impacts of dopant amount of La, catalyst dose, initial pH of the solution, irradiation time, dye concentration, and reuse were carried out and discussed in this research. The experimental findings reveal that the highest photocatalytic activity was achieved with the MgO-La2O3-10% MMO with photocatalysts with a degradation efficiency of 97.4% and 93.87% for TZ and PB, respectively within 150 min of irradiation. The addition of La to the sample was responsible for its highest photocatalytic activity. Response surface methodology (RSM) and Gradient Boosting Regressor (GBR), as artificial intelligence techniques were employed to assess individual and interactive influences of initial dye concentration, catalyst dose, initial pH and irradiation time on the degradation performance. The GBR technique predicts the degradation efficiency results with R2 = 0.98 for both TZ and PB. Moreover, ANOVA analysis employing CCD-RSM reveals a high agreement between the quadratic model predictions and the experimental results for TZ and PB (R2 = 0.9327 and Adj-R2 = 0.8699, R2 = 0.9574 and Adj-R2 = 0.8704, respectively). Optimization outcomes indicated that maximum degradation efficiency was attained under the optimum conditions: catalyst dose 0.3 g/L, initial dye concentration 20 mg/L, pH 4, and reaction time 150 min. On the whole, this studyconfirms that the proposed artificial intelligence (AI) techniques constituted reliable and robust computer techniques for monitoring and modeling the photodegradation of organic pollutants from aqueous mediums by MgO-La2O3-MMO heterostructure catalysts.

Background:The relationship of body mass index (BMI) and waist circumference (WC) with body fat rate (BFR) was analyzed frequently using linear model with normal distribution assumption. We aimed to investigate the association between of them using beta regression more applicable to BFR data to gain a deeper understanding of the best predictors of BFR.Methods:We analyzed 1087 middle-aged or elderly people from the Lanzhou rural cardiovascular and cerebrovascular disease and risk factor study. The location submodel (LSM) of the multivariate beta regression was used to evaluate the effect or interactions of BMI and WC on BFR while its precision submodel (PSM) was fitted synchronously to evaluate the impact of all entered factors on the variance of BFR.Results:Overall, the BFR had a mean of 0.28 with a standard deviation of 0.07. LSM of the multivariate beta regression showed that overweight (OWBMI) or general obesity (GOBMI) increased the likelihood of BFR increase by 18% (95%CI: 15%~22%) or 36% (95%CI: 31%~42%) respectively but central obesity (COWC) only by 12% (95%CI: 9%~16%). Moreover, there existed the interactions of BMI and WC on BFR and the results showed that compared to normal or underweight with BMI and non-central obesity, OWBMI+COWCcould increase the likelihood of BFR increase by 33% (95%CI: 28%~37%) and GOBMI+COWChad a 54% (95%CI: 48%~61%) increase the likelihood of BFR increase. In addition, PSM showed that the variance of BFR decreased in some cases.Conclusion:In the beta regression BFR could be predicted with BMI or WC but BMI better and the combination of BMI and WC could increase their individual predictive performance.

Published: August 2022

Purpose
To evaluate the pooled diagnostic performance control MRI for prediction of recurrent prostate cancer (PCa) after high-intensity focused ultrasound (HIFU).
Materials and Methods
MEDLINE, EMBASE, and Cochrane library databases up to December 31st 2021 were searched. We included studies providing 2x2 contingency table for diagnostic performance of MRI in predicting recurrent PCa after HIFU, using control biopsy as reference standard. The quality of the included studies was assessed using Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2). Sensitivity and specificity were pooled and displayed in a summary receiver operating characteristics (SROC) plot. Meta-regression analysis using clinically relevant covariates was performed for the causes of heterogeneity.
Results
19 studies (703 patients) were included. All included studies satisfied at least four of the seven QUADAS-2 domains. Pooled sensitivity was 0.81 (95% CI 0.72–0.90) with specificity of 0.91 (95% CI 0.86–0.96), with area under the SROC curve of 0.81. Larger studies including more than 50 patients showed relatively poor sensitivity (0.68 vs. 0.84) and specificity (0.75 vs. 0.93). The diagnostic performance of studies reporting higher nadir serum prostate-specific antigen levels (> 1 ng/mL) after HIFU was inferior, and differed significantly in sensitivity (0.54 vs. 0.78) rather than specificity (0.85 vs. 0.91).
Conclusions
Although MRI showed adequate diagnostic performance in predicting PCa recurrence after HIFU, these results may have been exaggerated.

Tirur village located ~2.5 km inland along the western coast of Andaman Island experienced marginal subsidence during the 2004 Sumatra-Andaman (Mw 9.3) earthquake, causing inundation by tidal waters. Observations made in 2005, 2009, 2010 and 2011 revealed reduction in inundation limits of the tidal-marsh. Geomorphic and GPS observations suggest that the area experienced gradual but faster uplift during post 2004 till 2009, followed by gradual uplift with slower pace, indicating process of post-seismic relaxation. Shallow stratigraphic records exhibit four earthquakes including the 2004 Sumatra-Andaman earthquake. Unit a massive clayey-silt suggests a deeper environment before 3500 yr BP. Overlying thick peat (Unit b) represents tidal-marsh or wetland, suggesting emergence at or above mean sea-level during Event-I, this uplift was during 3022-3500 yr BP (BCE 1897-1369). Unit c medium-coarse sand with prominent bi-directional structures, and sharp contact with underlying Unit b, indicates a tsunami by Event-II during 1147 ± 108 yr BP (CE 674-1098). We infer that this was a mega-earthquake occurred along Andaman-Arakan Segment producing a transoceanic tsunami. Event-II caused subsidence followed by gradual uplift during post-seismic relaxation as marked by comparatively finer (bottom) and coarser (upper) sediments in Unit d. The post-seismic process was like the 2004 event which did not leave tsunami deposit. The Event-III during CE 1712-1852 was a tsunami marked by fine yellowish medium-fine sand (Unit e), inundated the area with relatively low-energy conditions, correlated with CE 1762 Arakan earthquake. Event-III resulted uplift facilitating formation of overlying peat (Unit f). Finally, the area subsided during 2004 earthquake (Event-IV).

Malaria parasite resistant has been a major barrier to effective treatment of malaria. Therefore, the study aimed to evaluate the distribution of P. falciparum resistant Kelch protein gene on chromosome 13 (Kelch 13) and multidrug resistant (Pfmdr1) mutant genes among children aged five years and below who attended Mother and Child Hospital, Akure, Nigeria. Thin and thick smears were prepared from the blood collected aseptically through venepuncture from five hundred (500) children. Structured questionnaires were used to obtain demographic data from the respondents. Two hundred malaria positive samples were randomly selected from the 500 samples for PCR analysis to detect Pfmdr1 and Kelch 13 mutant genes. The results showed that of the 500 respondents, 288 (57.6%) were males while 212 (42.4%) were females. Pfmdr1distribution include: mixed group (mutant/wild) 38.5%, mutant gene 35.5%, wild gene 20.5% and the resistant genes were absent in 5.5% of the infected children. The mixed group of Pfmdr1 gene was higher among infants (51.9%), children with birth order 4 (60.0%) and children that have blood group B (51.3%), however, there is no significant difference in the distribution of Pfmdr1 between gender (χ2 = 0.634, df = 1, p > 0.05). There was a point mutation in the codon position 557 where the amino acid Alanine was replaced by Serine in the PfK13. The presence of Pfmdr1 mutant genes and point mutation in the PfK13 gene of P. falciparum among children, calls for development of innovative drugs targeted on these resistant strains.

Resprouting, one of the main fire-adapted traits, is crucial in population dynamics in response to wildfires or herbivory. This trait, common in angiosperms, is rare in conifers, being Pinus canariensis one of the few species able to resprout. We analyzed gene expression during wound-induced resprouting in 5 years-old Canarian pines. RNA was extracted at three dates, including control samples from remote branches, representing immediate response to wounding (R0), resprouting initiation (R1), and elongation (R2), and then hybridized to a microarray designed with 15000 cDNAs from Pinus canariensis transcriptome of meristematic activity. We found 1164 Differentially Expressed Genes (DEGs) as response to wounding grouped in 6 clusters across time points. Genes related to defense- and stress-response were mainly found to be overexpressed at R0, including disease resistance response protein 206-like, or pathogenesis-related proteins PR-4b-like, among others. We also found DEGs coding for transcription factors such as GROWTH-REGULATING FACTOR (GRF), FLOWERING-PROMOTING FACTOR (FPF), and the HOMEODOMAIN LEUCINE ZIPPER Class IV (HD-ZIP IV), mainly related to outgrowth processes and lateral organogenesis in plants, showing overexpression at R1 and R2, when new shoots were emerging. This data was compared to differential gene expression during apical growth in P. canariensis, suggesting similarities and differences between vegetative apical growth and regulation of lateral shoot development in response to mechanical wounding.
