Published: August 2024

Abstract
In the pre-prostate specific antigen era, patients with prostate cancer (PC) commonly presented with symptoms. Currently, most PC are diagnosed at an asymptomatic stage with abnormal digital rectal examination or raised prostate specific antigen. In rare cases, PC may infiltrate the rectum and cause symptoms mimicking rectal cancer. It is difficult to differentiate between the two based on clinical features alone. We here report our experience in managing an 86-year-old male, with no significant personal pathological history, who presented with diarrhea and occasional rectal bleeding without any lower urinary tract symptoms. Investigations concluded to a PC invading the rectum and the patient was referred to urology department.

Abstract
Hepatocellular carcinoma (HCC) in the caudate lobe presents surgical challenges due to the lack of distinct anatomical landmarks. This case report introduces a novel surgical approach combining Takasaki’s classification and indocyanine green negative counterstaining for precise anatomical caudate lobectomy. A 78-year-old patient with hepatocellular carcinoma in the caudate lobe underwent surgery following preoperative volumetric assessment. The method involved a glissonian approach for both left and right pedicles, coupled with meticulous dissection of hepatic pedicles of the caudate lobe guided by taping of left and right glissonian pedicles, followed by indocyanine green administration for improved visualization of caudate lobe boundaries. The procedure enabled complete tumor resection with minimal blood loss. At 50 months postsurgery, the patient maintains favorable liver function and performance status. This innovative approach offers a promising solution for precise resection of caudate lobe hepatocellular carcinoma, potentially improving surgical outcomes and long-term prognosis.

Authors: Ding Xuejiao , Tao Yichao , Hu Cong , Wu Xiaofeng 
Published: August 2024

Abstract
Perianal endometriosis represents a rare form of endometriosis occurring outside the pelvic cavity. Owing to its infrequency in clinical practice, this condition is highly susceptible to misdiagnosis and inappropriate treatment. This case report details a young female patient who was erroneously diagnosed with a perianal abscess. We conducted a para-anal mass resection under spinal anesthesia, and subsequent histopathological examination definitively confirmed the diagnosis of perianal endometriosis.

Abstract
Extended distal pancreatectomy often requires resection of vascular structures and adjacent organs, potentially leading to gastric venous congestion. This case report describes a 49-year-old female who underwent radical antegrade modular pancreatosplenectomy for pancreatic ductal adenocarcinoma. During the procedure, segmental gastric venous congestion was observed and resolved by anastomosing the left gastric vein to the left adrenal vein. The in-hospital postoperative recovery was initially uneventful; however, the patient was readmitted because of intra-abdominal fluid collection that was managed with antibiotics. Pathological examination confirmed moderately differentiated ductal adenocarcinoma with lymphovascular invasion. The patient received adjuvant mFOLFIRINOX therapy and remains disease-free 12 months after surgery with adequate patency of the anastomosis. This case highlights the importance of recognizing and addressing gastric venous congestion during radical antegrade modular pancreatosplenectomy to prevent complications, such as delayed gastric emptying or gastric necrosis, and proposes left gastric vein to left adrenal vein anastomosis as an effective intraoperative solution.
Adhesive duodenal obstruction: a report of a previously undescribed pathology
Authors: Baker Akil , Walcott-Bremmer Michelle , Harriott John , Mitchell Derek 
Published: August 2024

Abstract
Adhesive small bowel obstruction is thought to be a disorder limited to the jejunum and ileum. As a result, the list of aetiologies for duodenal obstruction does not include adhesions. We report the case of a patient who presented with gastric outlet obstruction (GOO), but with no lesions identified on cross-sectional imaging or endoscopy. Laparoscopy revealed duodenal adhesions as the cause of her GOO. Kockerization of the duodenum led to resolution of her symptoms. This previously undocumented finding leads us to suggest that laparoscopy should be considered in patients who have features highly suspicious for GOO, but have no cause identified on investigation.
A road to surgical success: a case report of huge retroperitoneal idiopathic non-pancreatic cyst in a 6-year-old child at tertiary hospital, Muhimbili National Hospital

Abstract
In most reported cases, pancreatic pseudocysts are the most commonly reported cases and mostly occur in adults. Idiopathic non-pancreatic pseudocyst is rarely reported among children. We are reporting a rare case of retroperitoneal pseudocyst in a 6-year-old male with a 4-week history of abdominal swelling. He had asymmetrical abdominal distention on the right lumber and iliac regions with a smooth surface measuring 12 × 22 cm in its largest dimension. CT scan showed a mesenteric cyst, ipsilateral hydronephrosis, and intrahepatic duct dilatations. Intraoperatively, a retroperitoneal cystic mass was completely excised histologically confirmed pseudocyst. The patient was discharged home after fully recovery after 4 days of surgery. Surgical interventions remain to be the stay management of retroperitoneal pseudocysts with an earlier full recovery. Open surgical technique remains to be a preferred approach, especially for the large and complex retroperitoneal cysts.

Abstract

Background
Understanding mortality among travellers is essential for mitigating risks and enhancing travel safety. However, limited evidence exists on severe illnesses and injuries leading to death among travellers, particularly in low- and middle-income countries and remote regions.

Methods
We conducted a retrospective census study using country-level observational data from death certificates of travellers of seven South American countries (Argentina, Brazil, Chile, Colombia, Ecuador, Peru and Uruguay) from 2017 to 2021. Causes of death were evaluated using ICD-10 codes, categorized into non-communicable diseases (NCDs), communicable diseases and injuries. We quantified causes of death by demographic characteristics (e.g. age, sex) and geographical variables. Chi-square tests were used to assess differences between categories. We calculated crude mortality rates and incidence rate ratios (IRRs) per country’s subregions.

Results
A total of 17 245 deaths were reported. NCDs (55%) were the most common cause of death, followed by communicable diseases (23.4%) and injuries (18.1%). NCD-associated deaths increased after age 55 years and were highest among ≥85 years. Communicable diseases were more common at younger age (&lt;20 years). Injury-associated deaths were more common in men (79.9%) and 25–29-year-olds (17.1%). Most deaths (68.2%) could have been avoided by prevention or treatment. Mortality risk was higher among travellers in bordering regions between countries. In Roraima (Brazil) and Norte de Santander (Colombia), locations bordering Venezuela, the death IRR was 863 and 60, respectively. These countries’ reference mortality rates in those regions were much lower. More than 80% of the deaths in these border regions of Brazil and Colombia involved Venezuelan citizens.

Conclusion
The study identified risk factors and high-risk locations for deaths among travellers in seven countries of South America. Our findings underscore the need for specific health interventions tailored to traveller demographics and destination to optimize prevention of avoidable deaths in South America.
Optimization of Parameters for Atom Probe Tomography Analysis of β-Tricalcium Phosphates

Published: August 2024

Abstract
The biocompatibility and resorption characteristics of β-tricalcium phosphate (β-TCP, Ca3(PO4)2) have made it a coveted alternative for bone grafts. However, the underlying mechanisms governing the biological interactions between β-tricalcium phosphate and osteoclasts remain elusive. It has been speculated that the composition at grain boundaries might vary and affect β-TCP resorption properties. Atom probe tomography (APT) offers a quantitative approach to assess the composition of the grain boundaries, and thus advance our comprehension of the biological responses within the microstructure and chemical composition at the nanoscale. The precise quantitative analysis of chemical composition remains a notable challenge in APT, primarily due to the influence of measurement conditions on compositional accuracy. In this study, we investigated the impact of laser pulse energy on the composition of β-TCP using APT, aiming for the most precise Ca:P ratio and consistent results across multiple analyses performed with different sets of analysis conditions and on two different instruments.
Professional Boundaries
Authors: Curry Saundra 
Published: August 2024

Abstract
Professional boundaries are something that all healthcare providers have to deal with on a daily basis. They are part of the caring professions’ professionalism skills, and most practitioners rarely think about the issues involved. However, there are situations which occur that can test any healthcare practitioner’s skills. Because each patient encounter is unique, hard and fast rules do not always work, and a clinician needs to know how the rules should help in making decisions. The following scenarios are a review of some of these situations with a discussion about the consequences that can ensue.
An Overview of the Legal Process, Depositions, and Testifying in Court
Authors: Hicks James S. , Street Jeffrey R. 
Published: August 2024

Abstract
The occurrence of a medical event resulting in an adverse outcome often results in civil litigation. The stages of this process and its effect on the involved physician are illuminated in this chapter as the physician becomes the defendant in a case where there was no indication at the time of the incident that any permanent harm had occurred. The steps involved in proving a tort (the patient’s allegations of injury) are enumerated along with detailed explanations of each and a description of the oft-delayed elements of the legal process. The roles of attorneys, judges, experts, and insurance carriers are described. No physician considers the ordeal of a lawsuit as anything but devastating, even when there is a jury finding of no negligence or a dismissal of the suit by the plaintiff. The role the defense attorney must play is to be both expert in the law and a comforting advocate for his client.

ABSTRACT

Introduction
Many veterans with serious illnesses, such as end-stage kidney disease requiring dialysis and advanced cancer requiring treatment infusions, must make complex decisions about their current and future medical care. Advance care planning (ACP) is a process where individuals identify, express, and communicate their personal values, life goals, and preferences for care. ACP may be feasible in chemotherapy infusion centers or chronic dialysis centers during patient treatment.

Materials and Methods
We assessed the feasibility of a licensed vocational nurse (LVN) facilitator to help veterans review the PREPARE for Your Care program (www.prepareforyourcare.org) and complete an advance directive (AD) in an outpatient hemodialysis unit or a chemotherapy infusion center. PREPARE For Your Care is an evidence-based online program with written pamphlets and ADs that prepares patients to participate with clinicians in making medical decisions. We measured the time to complete a session and the level of assistance required from LVNs via LVN self-report. Self-reported ease-of-use, comfort, and helpfulness were assessed on a 10-point Likert scale from 1 (not at all) to 10 (very).

Results
Twenty-eight patients were enrolled (mean age ± SD: 67 ± 11 years); all (100%) completed PREPARE and the AD within 1 session. The mean completion time was 100 (±40) minutes. Most of the patients required considerable assistance from the LVN. The mean scores were 8.0 of 10 for ease-of-use (±2.3), 7.7 of 10 (±2.8) for comfort, and 8.2 of 10 (±2.3) for helpfulness.

Conclusions
This pilot study demonstrates that using PREPARE as an ACP tool for veterans may be feasible for patients during hemodialysis and chemotherapy infusion. Patients required considerable assistance from the LVN to complete PREPARE. Hemodialysis and chemotherapy infusion are opportunities when patients have time and space to consider ACP.
Rossby wave instability and substructure formation in 3D non-ideal MHD wind-launching discs
Authors: Hsu Chun-Yen , Li Zhi-Yun , Tu Yisheng , Hu Xiao , Lin Min-Kai 
Published: August 2024

ABSTRACT
Rings and gaps are routinely observed in the dust continuum emission of protoplanetary discs (PPDs). How they form and evolve remains debated. Previous studies have demonstrated the possibility of spontaneous gas rings and gaps formation in wind-launching discs. Here, we show that such gas substructures are unstable to the Rossby wave instability (RWI) through numerical simulations. Specifically, shorter wavelength azimuthal modes develop earlier, and longer wavelength ones dominate later, forming elongated (arc-like) anticyclonic vortices in the rings and (strongly magnetized) cyclonic vortices in the gaps that persist until the end of the simulation. Highly elongated vortices with aspect ratios of 10 or more are found to decay with time in our non-ideal magnetohydrodynamic (MHD) simulation, in contrast with the hydro case. This difference could be caused by magnetically induced motions, particularly strong meridional circulations with large values of the azimuthal component of the vorticity, which may be incompatible with the columnar structure preferred by vortices. The cyclonic and anticyclonic RWI vortices saturate at moderate levels, modifying but not destroying the rings and gaps in the radial gas distribution of the disc. In particular, they do not shut-off the poloidal magnetic flux accumulation in low-density regions and the characteristic meridional flow patterns that are crucial to the ring and gap formation in wind-launching discs. Nevertheless, the RWI and their associated vortices open up the possibility of producing non-axisymmetric dust features observed in a small fraction of PPDs through non-ideal MHD, although detailed dust treatment is needed to explore this possibility.

ABSTRACT
One necessary step for probing the nature of self-interacting dark matter (SIDM) particles with astrophysical observations is to pin down any possible velocity dependence in the SIDM cross-section. Major challenges for achieving this goal include eliminating, or mitigating, the impact of the baryonic components and tidal effects within the dark matter halos of interest – the effects of these processes can be highly degenerate with those of dark matter self-interactions at small scales. In this work, we select 9 isolated galaxies and brightest cluster galaxies (BCGs) with baryonic components small enough such that the baryonic gravitational potentials do not significantly influence the halo gravothermal evolution processes. We then constrain the parameters of Rutherford and Møller scattering cross-section models with the measured rotation curves and stellar kinematics through the gravothermal fluid formalism and isothermal method. Cross-sections constrained by the two methods are consistent at $1\sigma$ confidence level, but the isothermal method prefers cross-sections greater than the gravothermal approach constraints by a factor of $\sim 3$.
General non-linear fragmentation with discontinuous Galerkin methods
Authors: Lombart Maxime , Bréhier Charles-Edouard , Hutchison Mark , Lee Yueh-Ning 
Published: August 2024

ABSTRACT
Dust grains play a significant role in several astrophysical processes, including gas/dust dynamics, chemical reactions, and radiative transfer. Replenishment of small-grain populations is mainly governed by fragmentation during pair-wise collisions between grains. The wide spectrum of fragmentation outcomes, from complete disruption to erosion and/or mass transfer, can be modelled by the general non-linear fragmentation equation. Efficiently solving this equation is crucial for an accurate treatment of the dust fragmentation in numerical modelling. However, similar to dust coagulation, numerical errors in current fragmentation algorithms employed in astrophysics are dominated by the numerical overdiffusion problem – particularly in three-dimensional hydrodynamic simulations where the discrete resolution of the mass-density distribution tends to be highly limited. With this in mind, we have derived the first conservative form of the general non-linear fragmentation with a mass flux highlighting the mass transfer phenomenon. Then, to address cases of limited mass density resolution, we applied a high-order discontinuous Galerkin scheme to efficiently solve the conservative fragmentation equation with a reduced number of dust bins. An accuracy of $0.1{\!-\!}1~{{\ \rm per\ cent}}$ is reached with 20 dust bins spanning a mass range of 9 orders of magnitude.
Magma Evolution and Storage Conditions in an Andesite–Dacite Volcanic System, Whakaari (White Island), New Zealand

Published: August 2024

Abstract
Whakaari (White Island) is an active andesite–dacite volcano located on New Zealand’s northernmost continental shelf. During a series of Strombolian eruptions in 1976–2000 it produced high-Mg andesite magmas (Mg#: 65–74; SiO2: 55–58 wt %). It has already been suggested that the production of these magmas involved complex interaction between stored and ascending magmas in a mid-crustal magma chamber that forms part of a larger trans-crustal plumbing system. Here we re-examine this proposal by employing Rhyolite-MELTS 1.2.0 and Magma Chamber Simulator to simulate liquidus relationships for one of the 1976 to 2000 high-Mg andesites from Whakaari (P41600). It was found that production of the main phenocryst assemblage (olivine + Cr-spinel + orthopyroxene + clinopyroxene + plagioclase + magnetite), mineral compositions, and liquid line of descent (as determined from matrix glasses) requires 30–60% fractional crystallisation at comparatively low pressures (&lt; 100 MPa) and melt-H2O concentrations (&lt; 2 wt %) with moderate fO2 (from Ni–NiO to one log unit above Ni–NiO) and temperatures of 1140°C to 1000°C. At least 0.5 wt % water is required to stabilise olivine at 60 MPa although original magmatic water concentrations may have been significantly higher. The early loss of magmatic water is a predictable consequence of both the low pressures of fractionation and the partitioning of H2O into a CO2-rich vapour phase. Polybaric crystallisation does not improve the simulations when compared to the isobaric model. Considering these observations, it is unlikely that evolution of the Whakaari high-Mg andesites involved significant fractionation within the mid- to lower-crust. However, there are aspects of magma evolution (particularly for FeOT and TiO2) that are not well modelled by any of our simulations. This may be because our model could not accurately simulate the effects of mixing between magmatic products or interaction between evolved melts and earlier crystallized mineral phases.
