Revision/Conversion Surgeries After One Anastomosis Gastric Bypass-An Experts' Modified Delphi Consensus.

There is a lack of evidence for treatment of some conditions including complication management, suboptimal initial weight loss, recurrent weight gain, or worsening of a significant obesity complication after one anastomosis gastric bypass (OAGB). This study was designed to respond to the existing lack of agreement and to provide a valuable resource for clinicians by employing an expert-modified Delphi consensus method. Forty-eight recognized bariatric surgeons from 28 countries participated in the modified Delphi consensus to vote on 64 statements in two rounds. An agreement/disagreement among ≥ 70.0% of the experts was regarded to indicate a consensus. A consensus was achieved for 46 statements. For recurrent weight gain or worsening of a significant obesity complication after OAGB, more than 85% of experts reached a consensus that elongation of the biliopancreatic limb (BPL) is an acceptable option and the total bowel length measurement is mandatory during BPL elongation to preserve at least 300-400cm of common channel limb length to avoid nutritional deficiencies. Also, more than 85% of experts reached a consensus on conversion to Roux-en-Y gastric bypass (RYGB) with or without pouch downsizing as an acceptable option for the treatment of persistent bile reflux after OAGB and recommend detecting and repairing any size of hiatal hernia during conversion to RYGB. While the experts reached a consensus on several aspects regarding revision/conversion surgeries after OAGB, there are still lingering areas of disagreement. This highlights the importance of conducting further studies in the future to address these unresolved issues.

Morphometric evaluation of Aedes aegypti (Linnaeus, 1762) and Culex quiquefasciatus (Say, 1823) (Diptera: Nematocera: Culicidae) of different metamorphosis stages

Morphometric comparison of Aedes. aegypti and Culex. quiquefasciatus larval instars and pupae were done through the measurements of total body length, length of head, thorax and abdomen as well as length and width of different external body parameters. From linear regression of the data from different larval instars showed that the important morphological features were the size of the head, thorax and abdomen of the Ae. Aegypti and Cx. Quinquefasciatus. They increased significantly with the advanced metamorphosis stages (p≤0.05). Size of the external larval organs viz. antennae, comb spine, siphon, anal papilla were also significantly (p≤0.05) increased during stages of metamorphosis. Bangladesh J. Zool. 51(3): 329-343, 2023

The Use of Acartia tonsa Nauplii during the First Days of Feeding on the Ontogeny of the Digestive System of Greater Amberjack (Seriola dumerili Risso, 1810)

The effect of feeding greater amberjack with copepod nauplii (Acartia tonsa) on the ontogeny of the digestive system was observed until 40 days after hatching (DAH). Copepods are part of the diet of fish larvae in nature, and they are rich in highly unsaturated fatty acids and free amino acids that enhance the digestive capacity of the fish. In a marine hatchery, four cylindroconical tanks of 2,700 L were stocked with about 150 × 103 greater amberjack larvae (Seriola dumerili) in each. The larvae were initially fed from 3 to 17 DAH in two tanks with copepod nauplii and rotifers (Brachionus sp.; Copepods group), while in the other two tanks, they were fed only with rotifers (Control group) during the same period. All the tanks were fed with rotifers (3–27 DAH), Artemia nauplii (12–22 DAH), enriched Artemia metanauplii (20–30 DAH), and formulated diet (25–40 DAH). Fish samples were taken regularly (every 2 or 4 days) for histological analysis and every day for the measurement of total length (TL). The TL was 3.7, 4.5 ± 0.1, 6.1, 11, 17.3 ± 0.1 and 20.3 ± 2.3 mm at 4, 10, 16, 22, 30, and 40 DAH, respectively. Copepod-fed fish showed higher TL in the last 2 days of the trial (p <0.05), while mortality rates were lower in the beginning of the trial 10–17 DAH, (p <0.05). In addition, copepods-fed fish had less skeletal deformities (p <0.05). Pyloric caeca appeared earlier in the Copepods group compared with the Control, while the length and surface of the villi, the abundance of goblet cells/100 μm of intestine length, and the area covered with lipid vacuoles in the liver were significantly higher in the Copepods group (p <0.05). We can conclude that the use of copepods in the diet of the greater amberjack larvae can improve the ontogeny of the digestive system.

Length-based growth, mortality, and biological reference points of Chrysichthys nigrodigitatus (Lacepède, 1803) from the Yeji arm of Lake Volta, Ghana

Individuals of Chrysichthys nigrodigitatus from Lake Volta, Ghana (West Africa), were examined between January and December 2020 for growth, mortality, and exploitation rate using total length measurement. Monthly length-frequency data were collected from 244 samples and analysed using the FiSAT II Tool. The estimated asymptotic total length (L∞), the coefficient of growth (K), and the calculated growth performance index (phi) were 27.3 cm, 0.57, and 2.63 pear year, respectively. The total mortality rate (Z), natural mortality rate (M), and fishing mortality rate (F) were 1.57, 0.92, and 0.66 pear year, respectively. The exploitation rate (E = 0.42) was below the optimum level of 0.5, which indicates that the species is underexploited. Based on the Emsy (0.56) value, analyses show that the exploitation rate is below the sustainable limit, hence the need for continuous monitoring of fishing efforts to ensure that the limit reference point is not exceeded.

Effects of female hair braiding on selected facial Anthropometrics

Objective: Effects of heavy hair braiding on facial anthropometrics have raised concerns in recent times. These concerns arise from the potential impact on cultural practices and the implications for physical appearance and self-perception. This study aimed to investigate the effects of braiding on the soft anthropometrics in face and head among students in Alex Ekwueme Federal University Ndufu Alike, Ebonyi State, Nigeria. Materials and methods: A total of 503 healthy participants, aged 19 to 25 years, were randomly recruited from an institution. Measurements of total facial length and face width were taken. A structured questionnaire was used, that contain anatomical, theatrical, and socio-psychological questions to evaluate the effects of braiding on the face and head. Participants responded using a Likert scale. Results: Mesocephalic shape was the commonest classification of the skulls based on cephalic indices. Relationship between age and facial parameters of the study population showed significant positive correlation (r = 0.17, p<0.05). Majority of respondents agreed that face type/facial structure determines the type of braid (n = 138) and braid can pull the forehead backward (n = 102). Conclusion: This study will contribute to understanding the influence of braiding on facial and head anthropometrics among Nigerian students. This information can inform discussions on cultural practices and their implications for physical appearance and self-perception.

Revealing further insights on extralimital records of Burmeister's porpoise (Phocoena spinipinnis, Burmeister, 1865) in the Southwestern Atlantic Ocean

Abstract Burmeister's porpoise (Phocoena spinipinnis) is an endemic species found in both the South Pacific and Atlantic Oceans, along the coastal regions of South America. In the Southwestern Atlantic Ocean, the species is reported from Tierra del Fuego, Argentina to Santa Catarina, Brazil, and the Falkland Islands. This study provides new insights on two stranded P. spinipinnis specimens in Southeastern Brazil, including the first occurrence in the state of Rio de Janeiro. Despite the advanced decomposition of the carcasses, which limited necropsy findings, we provide new data on the general characteristics of the specimens found in this extralimital geographical range, such as total body length, age, sex, vertebral count, and cranial measurements.

Effect of replacing fish meal with black soldier fly larvae meal on growth performance and economic efficiency of Nile tilapia

This study evaluated the effect of replacing fish meal (FM) with black soldier fly (Hermatia illucens) larvae meal (BSFLM) on growth performance and economic efficiency of Nile tilapia (Oreochromis niloticus) production. The BSFLM replaced FM at 0, 25, 50 and 75% (T1, T2, T3, and T4, respectively). One thousand two hundred (1,200) all-male Nile tilapia fry were stocked in twelve hapas at Kenya Marine and Fisheries Research Institute (KMFRI), Sangoro aquaculture research station in Kenya, and hand-fed four times daily for 21 weeks. Thirty (30) fish were sampled biweekly from each hapa for measurement of total length and weight. Findings indicated that diet T3 outperformed all the other treatments in respect to final body weight (23.20 ± 1.15 g), daily weight gain (0.13 ± 0.02 g), final weight gain (23.09 ± 1.15 g), survival rate (96.74 ± 3.18 %), SGR (1.31 ± 0.03 % day-1), FCR (1.57 ± 0.02), feed efficiency (0.64 ± 0.02), and condition factor (1.92 ± 0.01). The cost per kilogram of feed was highest for control diet (USD 0.91) and lowest for 75% BSFLM diet (USD 0.79). Economic Conversion Ratio (ECR) was lowest for the 50% BSFLM diet (1.26 ± 0.14) and highest for the control diet (1.44 ± 0.14). Economic Profit Index (EPI) was highest for the 50% BSFLM diet (141.82 ± 7.88) and lowest for the 25% BSFLM diet (106.64 ±6.63). The findings reveal that 50 to 75% BSFLM inclusion is an ideal replacement for FM in Nile tilapia diets, and is technically and economically efficient for Nile tilapia production.

Short-beaked common dolphin (Delphinus delphis) total length estimation using laser photogrammetry off the southwest coast of Ireland

Measurements from 106 stranded short‐beaked common dolphins along the Irish coast were taken between March 2017 and March 2023. Data were collected from the Irish Necropsy Project and Irish Cetacean Stranding Scheme. Total length measurements were gathered from 103 individuals where the tail flukes were still attached. These ranged between 96–238cm, mean 185.7cm, SD 31.43cm. Males (n = 58) ranged from 96–238cm, averaging 189cm, SD 34.64cm. Females (n = 40) measured 117.5–231cm, averaging 181cm, SD 25.80cm. Scaled dorsal fin photos were taken from stranded dolphins to formulate an equation to estimate the total length of live dolphins. The total lengths of 29 live common dolphins were estimated off the southwest coast of Ireland using laser photogrammetry and dorsal fin dimensions between March 2018–April 2019. Total lengths for three stranded dolphins with amputated tail flukes were also estimated. Dorsal fin base lengths were the most accurate predictor of total length R2 = 0.78. Total length estimates ranged between 143.77–242.25cm, averaging 194.78cm, SD 20.05cm. The adoption of laser photogrammetry as a measurement tool warrants further exploration as a means to reduce potential disruption from aerial systems and enhance the utility of behavioural and photo‐ID images. This study describes a non‐invasive technique with a range of possible applications for understanding pod size structure and seasonality due to this species’ approachable behaviour and inquisitive nature.

The use of a total bowel length measurement protocol may reduce reoperations and complications after single-anastomosis duodenal switch.

Most surgeons who perform single-anastomosis duodeno-ileal switches (SADI-S) use a pre-determined common channel length without measuring total bowel length (TBL). However, TBL varies between patients, and a standardized common channel length could contribute to malabsorptive complications and reoperations following SADI-S. The purpose of this study was to determine whether using a TBL measurement protocol to individualize common channel length would be associated with reduced reoperations and complications. A prospectively maintained data registry was retrospectively reviewed to identify all patients who underwent SADI-S between September 2017 and February 2022. In April 2021, we began using TBL measurements during SADI-S with 40% of the TBL used as the length for the common channel. Outcomes pre-TBL and post-TBL measurement protocol were compared. A total of 119 SADI-S recipients (59 pre-TBL; 60 post-TBL) were included. The pre-TBL group had a higher frequency of reoperations (23.7% vs 1.7%, p < 0.001) and late complications (29.3% vs 3.3%, p < 0.001). The mean time to reoperation was 13.7months in the pre-TBL group and 6.7months in the post-TBL group (p = 0.347). Patients in the post-TBL group had significantly higher serum albumin levels at 3months (4.2g/dL vs 3.5g/dL, p < 0.001), 6months (4.1g/dL vs 3.6g/dL, p < 0.001), and 12months (4.2g/dL vs 3.8g/dL, p = 0.023) postoperatively when compared to the pre-TBL group. Using TBL measurements to individualize common channel length was associated with a significant reduction in reoperations and late complications following SADI-S.

Captive breeding, embryonic and larval development of Ranitomeyavariabilis (Zimmermann & Zimmermann, 1988), (Anura, Dendrobatidae).

A solid basis to address the conservation challenges of amphibians requires an increased knowledge on their natural history and biology. Recent data on reproductive modes in amphibians suggest that they are much more complex and variable than previously thought but understudied. However, detailed information on the reproductive history is especially important to fill the current knowledge gaps. Following recent taxonomic changes in Ranitomeyavariabilis, information about captive-breeding management, image-based measurements of total length and surface area of the silhouette for individuals from embryonic to metamorphic development, and detailed larval staging for captive-bred specimens are provided from French Guiana. The development of R.variabilis from the stage eight (Gosner 1960) through metamorphosis took 79 to 91 days (n = 6) with a survival rate of 46%. The developmental stages largely matched those of the generalized staging system of Gosner (1960), with differences in the stages when labia and teeth differentiation and atrophy of the oral apparatus occurred. Compared with other studies the total length of R.variabilis tadpoles was greater at given stages than those of R.variabilis from a Peruvian population and those of the sister species, R.amazonica. Other studies concerning growth curves based on surface area data revealed that R.variabilis tadpoles at peak size were larger than those of R.amazonica, R.imitator, R.reticulata, R.sirensis, and R.vanzolinii, but smaller than R.benedicta. Our results represent the first embryonic and larval staging for R.variabilis, and detailed information is provided on their initial life phases. These data may facilitate the identification of R.variabilis tadpoles in the wild, as well helping to clarify the biogeographical distribution and taxonomic arrangement of the species. In addition, knowledge is added to the captive-breeding methodology for the species.

Population Dynamics of Seabreams (Pagrus caeruleostictus, Pagellus bellottii, Dentex angolensis and Dentex congoensis) from the Coast of Ghana, West Africa

Stock assessment indicators of Pagrus caeruloestictus, Pagellus bellotti, Dentex angolensis and Dentex congoensis from Ghana’s coastal waters were estimated between July 2018 and June 2019. Total length measurements of 2489 samples were collected from some selected coastal communities along the Greater Accra region of Ghana and analyzed using FISAT II Tool. The asymptotic length (L∞) for P. caeruleostictus, P. bellottii, D. angolensis and D. congoensis was 39.9 cm, 31.5 cm, 31.5 cm and 28.4 cm, respectively. The growth rate (K) was 0.18 yr-1 for P. caeruleostictus, 0.36 yr-1 for P. bellottii, 0.75 yr-1 for D. angolensis and 0.83 yr-1 for D. congoensis. The current exploitation rate (E) for P. caeruloestictus, P. bellotti, D. angolensis and D. congoensis was above the optimum level of 0.5, indicating that these species are facing high fishing pressure. To ensure sustainable management of the overexploited fish species, the need for relevant management measures such extension of the closed fishing season, reduced fishing effort and others are urgently required.

Unexpected Records of Newborn and Young Sharks in Ligurian and North Tyrrhenian Seas (North-Western Mediterranean Basin)

Between 2007 and 2022, 112 specimens of newborn and young pelagic sharks were recorded in the waters of Tuscany Region, in the South Ligurian–North Tyrrhenian Seas (north-western Mediterranean basin). The sharks belonged to the Carcharhinus plumbeus (n = 14), Prionace glauca (n = 66), Isurus oxyrinchus (n = 16), Mobula mobular (n = 5) Alopias vulpinus (n = 7) and Hexanchus griseus (n = 4) species. Each animal was correctly identified thanks to the photographs or videos collected. All specimens were incidentally captured with set nets in inshore shallow waters, except bluntnose six-gill sharks, which were bycatch of deep-water bottom-trawl fishery. Body mass, sex, total length and biometric measurements were recorded in 34 baby sharks following the Mediterranean Large Elasmobranches Monitoring (MEDLEM) protocol. The presence of very evident and often non-healed umbilical scar confirmed that some of the sample specimens were newborn. Further confirmation came from the comparison between the total length observed and the size at birth known for the sampled species as reported in the literature. Some baby sharks were preserved in the Museums of Natural History of Pisa and Florence University collections. The importance of the coastal area studied as a possible shark nursery is discussed.

Early life traits of the common two-banded seabream, Diplodus vulgaris (Perciformes: Sparidae), inhabiting the shallow waters of Gökçeada Island, Turkey

Daily growth rates and pelagic larval duration were investigated in the common two-banded seabream (Diplodus vulgaris). Fish were sampled using a beach seine from the shallow waters of Gökçeada Island, Turkey, between June 2013 and June 2014. The minimum and maximum daily age estimates were 41 and 339 d, respectively. The mean daily growth rate of young-of-the-year D. vulgaris was 0.330 mm·d–1. Our results showed that D. vulgaris exhibits a Type Ia settlement-mark with a pelagic larval duration of 29 d. The hatching period occurred from November to April. The maximum hatching frequencies were observed in winter, when the water temperature was relatively low. The natural logarithm of young-of-the-year abundance data was plotted against age, and the instant mortality coefficients were estimated. The relationships between total length and otolith morphometric measurements (otolith length [OL], width [OW], and radius [OR]) were defined by linear equations. Furthermore, it was observed that this ratio exhibited a linear relationship with OL, OW, and OR and total length and daily age.

Stock Status of Green Tiger Prawn (Penaeus semisulcatus de haan, 1844) in Bombana and Adjacent Waters, Southeast Celebes, Indonesia

The high market demand for green tiger prawn (Peneus semisulcatus de Haan) has caused intensive fishing for this resources and tended to threaten their sustainability. Studies of stock status are the main foundations for formulating a management for sustainable utilization. The purpose of this study was to determine the stock status of green tiger prawn in the Bombana and adjacent waters, South-east Celebes. The study was conducted from April to November 2021 using a survey method. The study results revealed that the green tiger prawn growth pattern was negative allometric and that the ratio of males and females was imbalanced. Based on total length measurement, length at first capture (Lc) and length at first mature (Lm) were 37.42 cm and 38.72 mm respectively. While growth rate (K) and maximum total length (L∞) valued 1,7 per year and 58.9 mm respectively. The estimate total mortality rate (Z) was 2.57 per year, the fishing mortality rate (F) and natural mortality rate (M) were 1.12 per year and 1.45 per year, respectively. Recruitment pattern occured throughout the year with one peak in June. The exploitation rate (E) was 0.44 per year, therefore the stock status was categorized as fully exploited. In order to ensure the sustainability of the green tiger prawn, precautionary approach such as increasing fishing effort by 10 % of the current situation is strongly needed to be applied

Growth of Betutu fish (Oxyeleotris marmorata BLEEKER, 1852) in Tondano Lake, North Sulawesi

The introduction of non-natural species to new environments is one of the main factors reducing and extinction of local diversity. The purpose of this study was to analyze the growth of betutu fish (Oxyeleotris marmorata Bleeker, 1852) in Tondano Lake. This research was conducted using a purposive sampling method, fish samples were obtained from the catch in a time series every month, sampling using gill nets at five stations and calculating fish growth based on the frequency of total length measurements. Data were analyzed using FiSAT II software. The results showed that the growth of the betutu fish was relatively fast in terms of the growth coefficient (K) value obtained of 1,700 per year so that the breeding of this fish was increasingly dominant compared to the growth of local fish.

Corporotomy localization in inflatable penile implant surgery: learning curve and comparing different surgical approaches in high volume surgeons

Inflatable penile prostheses (IPP) is a viable solution for patients with erectile dysfunction unresponsive to or with contraindications for conservative treatment. In contrast to rapporting of IPP design and material modifications, no data exist regarding the effect of different surgical approaches during IPP implantation on the corporotomy site. The purpose of the present multi-center study was to investigate different IPP implantation surgical approaches and their influence the corporotomy site, while the effect of learning curve on the corporotomy site was also evaluated. Data was collected from 6 high-volume IPP surgeons. Surgical notes were searched for incision site, proximal and distal corporal length measurement, total length measurement, total cylinder length, length of rear tip extenders (RTE), surgery time, type of implant and reservoir placement while postoperative complications were also reported. The association between proximal/distal corporal length, the recorded covariates and infectious complications were examined. 1757 patients with virgin 3-piece IPP implantation were included in the analysis. The proximal/distal ratio averaged at 0.829 (SD ±0.293) in penoscrotal incisions (N=782), 0.687 (SD± 0.245) in infrapubic (N=1664) and 0.724 (SD± 0.179) in subcoronary (N=972) incisions. No significant differences where observed in the three highest volume surgeons. Correcting for significant covariates (diabetes mellitus, RTE, age) did not change this outcome. In the three highest volume surgeons, a more proximal incision resulted in significantly less RTE use. There was no difference in infectious complications with different surgical techniques (p = 0.280). Focusing on the data of the principal center, we found a decrease in the proximal/distal ratio of 8.41% per additional year of experience. We were unable to draw a firm conclusion about the difference in corporotomy site between different surgical approaches as such, but we found no significant difference between the highest volume surgeons using different techniques. Nevertheless, a significant effect of experience on the proximalization of the corporotomy was reported. none

Belly up or belly down: Effect of body position on snout vent length and total length measurements in American crocodiles (Crocodylus acutus)

Abstract The interpretation of morphometric data is relevant to understanding biological phenomena. Currently, little is known about the effect of body position on morphometric measurements in crocodylians as well as the extent to which these data are interchangeable. We investigated the effect of body position on snout-vent-length (SVL) and total-length (TL) measured ventrally (belly up) and dorsally (belly down) on 725 Crocodylus acutus (mean TL ventral and dorsal 68.49 cm and 69.82 cm, range = 33.1-185.4 cm and 33.8-185.4 cm) across South Florida, United States. We found evidence that body posture significantly influences SVL and TL measurements. However, regardless of body position, the variation found in SVL was less than 1 mm, and for TL was on average only 3 mm. We concluded that even though there is a difference when measuring American crocodiles belly up and belly down, there is a minimal effect on the outcome (less than half centimeter), which falls within the normal measurement instrument error (i.e., measurement tape) even more so under field conditions. If researchers concur that this is an acceptable error, then SVL and TL measurements taken belly up or belly down can be used interchangeably.

Reproductive Biology Pleco (Pterygoplichthys pardalis Castelnau 1855) in Ciliwung River

Pterygoplichthys pardalis is a type of fish that is widely used by people around the Ciliwung River as raw material for food production. In addition, P. pardalis has not been cultivated. The process of fish farming requires a number of information and data on fish such as reproductive biology. Therefore, the research aimed is calculating the reproductive aspects of P. pardalis. The result for this research can be applied for fish farmers to start P. pardalis bredding process. The methods used are P. pardalis sampling, measurement of total length and weight, dissection of samples, calculation of gonad weight and liver weight, egg diameter, fecundity, calculation of gonad maturity stages (GMS), gonadosomatic index (GSI), hepatosomatic index (HSI), relationship of fecundity with gonad weight, relationship of egg diameter with gonad weight, relationship of fecundity with total weight, and length-weight relationship. GMS calculation results showed most male fish found in GMS I, while females were most found in GMS IV. The smallest GSI value was found in GMS I and the highest was in GMS IV both in male and female and the fecundity was 737-3820 eggs with egg diameters ranging from 1.571 mm-4.310 mm. Both male and female P. pardalis have negative allometric growth patterns
