Introduction:

The COVID-19 epidemic is fast-evolving and restrictions to contain it changes quickly. The secondary attack rate (SAR) indicates the infectiousness at the household level, and it provides a clue of load of infections in the community. Rapid implementation of a large scale, but brief survey provides a nationally representative view of the pandemic's progression and impact as well as the effect of the measures taken to control the spread.

Materials and Methods:

This cross-sectional study was done for a period of 2 months July–August 2020, in one of the rural health and demographic surveillance system (HDSS) site in India among 11,507 households having 46,571 individuals with the objective to determine the prevalence of the COVID-19 infection and to estimate the family SAR. The data were collected using the mobile phone by calling the head of the households registered under the HDSS. The research tool was created using questions based on the guidelines provided by the Ministry of Health and Family Welfare, India. The interviewers were first trained in data collection.

Results:

The households of 33,780 individuals were contacted and 33 patients were diagnosed as COVID positive, prevalence rate of 0.1% was thus documented through telephonic survey. The mean age of COVID patients was found to be 37 ± 16 years, and 63% of the diagnosed patients were males, majority of them belonged to above poverty line households. During the survey, 46 individuals reported to have the symptoms suggestive of COVID, fever and cough were the most commonly reported symptoms. The family SAR of 17.2% was documented.

Conclusion:

Thus to conclude a low COVID-19 prevalence rate of 0.1%, a higher family SAR of 17.2% was reported in the current study. Timely diagnosis and quarantine of close contacts should be continued to be implemented rigorously to prevent the spread of the COVID-19 virus. These efforts will be useful to contain the epidemic before it reaches an alarming level in the rural areas.

Published: September 2022

CONTEXT:

Structured Feedback is a learning and assessment tool designed to provide feedback to students and educators to adjust learning and teaching during the training. Lack of provision of structured feedback to postgraduate (PG) medical students prompted us to plan a study to introduce a structured feedback module into the existing monthly assessment schedules in the Department of Transfusion Medicine.

AIM:

This study aims to introduce a structured feedback module and evaluate its efficacy after incorporation into the existing monthly assessment schedules for the PG students in the Department of Transfusion Medicine.

DESIGN AND SETTING:

A quasi-experimental study was commenced after obtaining clearance from the Institutional Ethics Committee in the Department of Transfusion Medicine for the students pursuing postgraduation in Transfusion Medicine.

METHODOLOGY:

A peer-validated feedback module was designed and implemented for MD students by the core team faculty. The students underwent the structured feedback sessions after each monthly assessment for of 3 months. One on one, verbal feedback was conducted using Pendleton's method, for monthly online assessment for the learning that happened during study period.

DATA COLLECTION AND STATISTICAL ANALYSIS:

The data were collected from the open-ended and closed-ended questions using Google form-based Student/Faculty perception and students’ pre-post self-efficacy questionnaires on 5-point Likert Scale and the quantitative data analysis was done using percentage of Likert scores, median values for each item for pre-and post-responses and comparison using nonparametric test – Wilcoxon signed-rank test. The qualitative data analysis was done using thematic analysis from the open ended questions.

RESULTS:

All (n = 9; 100%) the PG students strongly agreed and agreed (median score of 5 and 4) that the feedback they received made them aware of their learning gaps, enabled them in bridging those gaps and provided ample opportunity to interact with faculty. Both students and faculty agreed that the feedback session should be an ongoing and continuous process in the department.

CONCLUSION:

Both the students as well as faculty were satisfied with the implementation of the feedback module in the department. Students reported awareness about the learning gaps, identification of appropriate study resources, and ample opportunity to interact with faculty, after taking the feedback sessions. The faculty felt satisfied on the acquisition of new skill for delivering structured feedback to students.
Blood components utilization in hematopoietic stem cell transplantation: Thirteen-year analysis from an apex oncology center of India
Authors: Ojha Shashank , Patle Vijaya , Nagaraju P. , Khattry Navin
Published: September 2022

BACKGROUND:

Hematopoietic stem cell transplantation (HSCT) is a potentially curative treatment modality for a range of hematological disorders including malignancies. The increasing volumes of HSCTs impact transfusion services and the requirement of blood products vary depending on the primary disease, type and phase of transplant, and the HSCT donor type.

MATERIALS AND METHODS:

This study analyzed the factors affecting blood component requirements in patients undergoing HSCT. The authors studied the transfusion requirement of packed red blood cells (PRBC) and platelets (PLT) up to 100 days post-transplant among 617 adult patients undergoing HSCT during the study period (2007–2019).

RESULTS:

Requirement of PRBC and PLT was significantly higher (P < 0.05) in allogenic HSCT cases across all three phases of transplant compared to autologous HSCT. Unlike PRBC requirement, the PLT requirement was significantly higher during peri-transplant period for haploidentical HSCT and major ABO-incompatible HSCT group compared to matched related donor HSCT and ABO identical HSCT, respectively. In subset analysis based on diagnosis with leukemia as reference, the multiple myeloma group required less while the anemia group required more PRBC and PLT transfusions. The leukemia group required more PRBC than lymphoma group, while the PLT requirement was vice-versa.

CONCLUSION:

Factors such as allogeneic HSCT, haploidentical donor type, major ABO-incompatible HSCT, and primary diagnosis as leukemia or anemia were the predictors for increased need of blood products. As higher transfusion requirements may translate into increased costs of treatment, a study like this can help in managing blood component inventory and planning treatment costs of a HSCT program.

A study was conducted to assess and compare the knowledge of blood transfusion practices among medical students and residents in Lebanese and Saudi medical institutions. The online survey consisted of 26 questions: 4 about personal data and experience with transfusion and 22 about knowledge on transfusion practices in the areas of blood donation and donor selection, production and storage of blood components, selection of appropriate blood components, administration of blood components, transfusion reactions, and complications. One hundred and twenty-six students from Saudi Arabia, 84 students from Lebanon, 31 residents from Saudi Arabia, and 23 residents from Lebanon participated in the survey. There were no significant differences between students’ and residents’ levels of knowledge. Similarly, there was no difference between the students’ level of knowledge in the two countries. The correct responses (48% and 46%, for students and residents, respectively) were below the acceptable limit of 60% for both groups. This reflects the need for more vigorous and well-structured education and training for both students and residents.

INTRODUCTION:

Autologous stem cell transplantation (ASCT) is a well-established consolidation treatment for many hematologic cancers which delivers prolonged survival. A subset of patients’ adequate stem cell harvest is not achievable with a solitary use of granulocyte colony-stimulating agents (G-CSF). Generally, chemomobilization is employed for patients failing G-CSF and its most feared complication febrile neutropenia (FN).

MATERIALS AND METHODS:

Here, we aimed to investigate the impact of the FN in chemomobilization on apheresis outcomes and engraftment. One hundred and eighty-three patients with the diagnosis of lymphoma or myeloma who underwent chemomobilization between 2015 and 2020 were included in the study.

RESULTS:

Forty-three patients experienced FN. All patients received G-CSF. All myeloma patients were mobilized with 4 g/m2 cyclophosphamide, but it was heterogeneous for lymphoma patients. The precollection blood counts, harvested CD34+ hematopoietic stem cells (HSCs)/kg, apheresis count, and engraftment durations were recorded. Preapheresis leukocyte and platelet were lower in the FN group (P = 0,004 and P = 0,001). Peripheral CD34 HSCs and total harvested CD34 HSCs were similar among groups (P = 0.25 and P = 0.9). More apheresis was needed in the FN group, but it was not significant (P = 0.07). Undergoing ASCT was similar (P = 0.7); however, platelet and neutrophil engraftment durations were slower in the FN group (P = 0.05 and P = 0.001).

CONCLUSION:

Harvesting sufficient CD34+ HSCs from patients with FN is still feasible; however, FN treatment should begin promptly, and further apheresis sessions may be required.

Published: September 2022

Karl Landsteiner discovered ABO blood group system in the early 20th century, but still, uncertainty remains in immunohematology while detection of ABO subgroups or weaker variants. The presence of weak subgroups in patient samples gives rise to the discrepancy in forward (cell) and reverse (serum) grouping. We here report a case of the B(A) phenotype in a patient who was diagnosed with chronic liver disease with acute pancreatitis, requiring packed red blood cells due to anemia. The blood group discrepancy was resolved using serological testing and adsorption–elution technique. Blood grouping by the tube technique showed 2+ agglutination with anti-A antisera, strong agglutination (4+) with anti-B, anti-AB, and anti-D antisera, 4+ agglutination with A1 cells, and no agglutination with B cells and O cells in serum grouping. Results for both eluate and last wash were negative to all the donor cells used. This report highlights the importance of cell and serum grouping, solving blood group discrepancy, and also in providing crossmatch compatible blood components without delay. This rare phenotype in a patient is the first of its kind reported from India.

Published: September 2022

Although relatively rare among transfusion reactions, transfusion-related acute lung injury (TRALI) is a life-threatening condition, making its prevention, recognition, and early intervention extremely important. Although many etiological factors have been identified, the most common reasons are anti-human leukocyte antigen (anti-HLA) and anti-human neutrophil antigen antibodies that pass from the donor to the recipient during transfusion. TRALI was shown with transfusion of all kinds of blood products, however, it is rarely seen after stem cell infusion. Despite an adult case who developed TRALI after stem cell infusion, there is no pediatric case of TRALI associated with hematopoietic stem cell infusion in the previous literature. Here, we report a pediatric case with TRALI after infusion of the hematopoietic stem cell product from his female donor who has recently given birth 6 months ago. A 9-year-old patient with acquired aplastic anemia was admitted for hematopoietic stem cell transplantation (HSCT) from an ABO and 10/10 HLA compatible 21-year-old sister donor the unmanipulated stem cell product was planned to be infused in 4 h. At the last hour of infusion, the patient had acute hypoxemia, tachycardia, and bilateral pulmonary edema. He was diagnosed with TRALI and completely recovered with supportive therapy in 48 h. The anti-HLA antibody analysis of the donor showed positivity of anti-HLA-DPB1 antibodies. We wanted to emphasize the need for examination of anti-HLA antibodies of the donor and plasma depletion of the product to avoid TRALI in HSCTs from multiparous female donors.

Published: September 2022

BACKGROUND:

Liver transplantation (LT) is a complicated surgical procedure with high risk for massive intraoperative blood loss due to pre-existing coagulopathy, portosystemic shunts with collateral circulations, and splenomegaly. The transfusion service will direct most of their resources toward LT programs with great impact on cost. The purpose of this study was to evaluate single center transfusion strategies and to identify the risk factors associated with the intraoperative blood loss and blood transfusion.

METHODS:

The study includes 18 patients who underwent LT at Hospital Selayang between January 2020 and December 2020. Retrospective analysis of data included preoperative assessment of coagulopathy, intraoperative blood loss, and blood component transfusion.

RESULTS:

The mean age in the study group was 36.4 ± 12.68 years. The mean intraoperative blood loss was 4450 ± 1646 ml requiring 4.17 ± 3.3 packed red blood cell (PRBC) units, 7.56 ± 5.5 platelet units, and 9.50 ± 6.0 fresh-frozen plasma units. The independent risk factor for high blood loss (HBL) group was lower preoperative platelet count and it is statistically significant (P = 0.024). The HBL group is associated with higher usage of PRBC (P = 0.024) and platelet units (P = 0.031) and it is statistically significant. The length of stay (LOS) in intensive care unit (ICU) averaging 8.6 ± 4.95 days, and there is no significant differences comparing the HBL and LBL group (P = 0.552). The mortality <90 days for all recipients was 22.2%.

CONCLUSION:

The preoperative platelet count for is the most important factor associated with HBL in LT procedure. The usage of PRBC and platelet units was statistically higher in the HBL group. Comparing HBL and LBL patients, there is no difference in terms of the LOS in ICU postoperatively. A larger sample size would be needed in view of relatively small sample size.

Published: September 2022

Thrombotic thrombocytopenic purpura (TTP) secondary to dengue fever is a very unusual occurrence. Both conditions are fatal and can result in significant mortality and morbidity if left untreated. In this case, we present a young lady who suffered dengue fever followed by microangiopathic anemia, thrombocytopenic purpura, and altered sensorium. Investigations revealed microangiopathic hemolysis; there was no evidence of disseminated intravascular coagulation. As soon as, we diagnosed the patient as having TTP, we treated her with serial plasma exchange therapy, steroids, and monoclonal antibodies such as rituximab. The patient responded very well to the treatment and completely recovered from neurological symptoms and laboratory parameters also normalized. Hence, timely diagnosis and starting appropriate treatment immediately are key factors for successful outcomes.

Published: September 2022

We report the case of a 5-year-old girl with a rare P-null phenotype who presented for a neurosurgical procedure at our center. The case is unique as this patient was one of the two P-null phenotype cases reported in India and we report how we could successfully arrange a rare blood unit for her. As it was challenging to find a donor for her, autologous blood was collected. Despite iron supplementation and erythropoietin injections, her hemoglobin remained low and the required number of autologous units could not be collected. As a consequence of the search initiated with the international and regional rare donor registries, a donor was identified in a remote village in India. Despite the logistic hurdles due to the COVID pandemic, the blood could be transported safely for performing the surgery. A centralized database of rare donors needs to be established to meet such requirements.

Immune-mediated diseases wherein immune complex-mediated injury is predominant; plasma exchange remains a therapeutic option for vasculitis. Hepatitis B virus-associated polyarteritis nodosa (HBV-PAN) wherein immunosuppressants can be contraindicated, plasma exchanges have a proven role when combined with antiviral therapy. Plasma exchange by hastening the clearance of immune complexes is beneficial in acute organ dysfunction. A 25-year-old male presented with complaints of generalized weakness, tingling numbness and weakness of extremities, joint pain, weight loss, and rashes over arms and legs for 2 months. Hepatitis B workup showed high viral loads of HBV (34 million IU/ml) and hepatitis e antigen positivity (1129.06 U/ml). Cardiac workup showed elevated cardiac enzymes and decreased ejection fraction (40%–45%). The finding of contrast-enhanced computed tomography (CECT) chest and abdomen with CT angiogram abdomen was steady with medium vessel vasculitis. A diagnosis of vasculitis with probable etiology of HBV-related PAN with mononeuritis multiplex and myocarditis was made. He was treated with steroids, tablet tenofovir, and 12 sessions of plasma exchanges. On average, 2078 ml of plasma was exchanged during each session with 4% albumin as a replacement fluid using central femoral line dialysis catheter as vascular access on automated cell separator Optia ®Spectra (Terumo BCT, Lakewood, Co). He was discharged with the resolution of symptoms, including myocarditis and increase in power strength and still in follow-up. The present index case indicates that antiviral combined with plasma exchange after short-term corticosteroids is an effective therapy for HBV-PAN. TPE can be used as adjuvant therapy along with antiviral therapy in a rare disease like HBV-related PAN.

Published: September 2022

Anti-M antibody is one of the causes of severe fetal anemia and intrauterine death despite its relatively low frequency. A G3P2 26-year-old pregnant woman referred to our hospital at 29 weeks gestational age (WGA) with fetal hydrops. Her second pregnancy results in intrauterine fetal death at 35 WGA due to fetal hydrops. From ultrasound exam, we found singleton live fetus with ascites, cardiomegaly, and pericardial effusion. The peak systolic velocity in the fetal middle cerebral artery (PSV-MCA) was 1.44 multiples of the median corresponding to fetal anemia. The patient’s blood group was B RhD+M− N+. A reactive IgG anti-M antibody was detected at 37°C. Fetal hemoglobin (Hb) from the first cordocentesis was 2.2 g/dl and we perform multiple intrauterine transfusions and cesarean section at 34 WGA. The postdelivery Hb level was 10.2 g/dl and infant need three times packed red blood cell transfusions after delivery.

Authors: SaiLahari Kakarla V. M. , Abhinaya R. V. R. , Mutnuru Venkataramana
Published: September 2022

Background:

Cancer, like other traumatic life events, can generate negative and positive changes in psychological well-being. Negative changes are defined as posttraumatic disorders and positive changes are called posttraumatic growth (PTG). Patients who experience PTG show positive and meaningful changes in their emotional and cognitive life, which has a positive impact on their behavior.

Aim:

The current study aimed to examine the concept of PTG and its social and cultural aspects in cancer patients from rural background arena.

Settings and Design:

This was a cross-sectional observational study.

Materials and Methods:

One hundred and fifty-five cancer-diagnosed patients were included in the study. from a tertiary care hospital, and PTG Inventory (PTGI) was administered to assess the posttrauma growth

Statistical Analysis Used:

Data were analyzed using the SPSS statistics version 23. Descriptive statistics and inferential statistics were performed.

Results:

Cancer patients showed posttrauma growth of 67.95 (standard deviation: 6.65). Of dimensions of PTGI, the highest score was for “relating to others.” Women had higher PTG of 70.46 (3.7) than men. Cervical and breast cancer patients showed higher scores of 71.9 (2.9) and 70.1 (3.5), respectively.

Conclusions:

This study highlighted that women had more PTG and cervical and breast cancer patients had better scores.

Published: September 2022

Background:

Hip dysplasia is one of the most widespread hip disorders. Total hip arthroplasty (THA) is the preferred treatment in patients with cup placement choices in true or false acetabulum. The objective of this research was to compare the effectiveness of the two mentioned procedures.

Materials and Methods:

This study was a randomized, open-label, parallel-group clinical trial, in which 46 patients/51 hips with Crowe type 3 dysplastic hip having THA were assigned to two groups: Group 1 – patients who had cup placement in the true acetabulum and Group 2 – patients who underwent cup placement in the false acetabulum. The variables that were evaluated and analyzed included severity of pain using the visual analog scale (VAS), range of motion (ROM), gait ability, the need for repeated joint replacement, and the Harris Hip Score (HHS).

Results:

Forty-six patients/51 hips were included in the present study. The patients who were evaluated included 30 (65.2%) males and 16 (34.8%) females. The mean age in the population under study was 71.0 ± 10.22, and the mean body mass index of participants was 26.34 ± 2.22 kg/m2. The basic parameters in the two research groups were similar (P > 0.05). There were no significant differences between the two groups in terms of the mean values of VAS and ROM (P > 0.05); however, the mean HHS was significantly higher in the true acetabulum group, 57.90 ± 18.47 versus 48.29 ± 13.80 (P = 0.04).

Conclusion:

The effectiveness of cup placements both in the true and false acetabula was similar in all of the evaluated variables in terms of clinical outcomes except for HHS which was higher in the true acetabulum group. To further support the results of this research, it is recommended that more research be done on a greater population.

Published: September 2022

Background:

Atrial fibrillation (AF) with fast ventricular response over an overt accessory pathway (AP) (preexcited AF) with a short anterograde refractory period is a potentially malignant arrhythmia. This study aimed to evaluate the safety and efficacy of amiodarone for preexcited AF management.

Materials and Methods:

This study enrolled 103 patients with evidence of AP in electrocardiography. Patients with preexcited AF were included in the study. Intravenous amiodarone (300 mg) was infused for 30 min for all patients in the AF rhythm. Electrophysiological parameters were evaluated before amiodarone injection and 2 h after pharmacological or electrical cardioversion.

Results:

Antegrade and retrograde refractory periods of the atrioventricular node (AVN) and AP, as well as antegrade and retrograde Wenckebach points of AVN, were increased significantly after amiodarone infusion. Furthermore, the mean of the shortest preexcited RR interval was increased during the monitoring period. Comparing the preexcited index at the beginning of the study and before cardioversion (2 h later) revealed that the QRS complexes changed to a wider pattern as the preexcitation index changed from 80.61 to 92.26 (P < 0.001). Nineteen (18.4%) patients converted to the sinus rhythm with amiodarone infusion. No ventricular arrhythmia was detected during monitoring.

Conclusion:

Amiodarone could be considered a safe drug in patients with preexcited AF for rate control despite its relatively low efficacy in conversion to the sinus rhythm.
The Palaeogeography of Lake Pannon During Deposition of the Congeria rhomboidea Beds
Authors:   University of Szeged, Hungary, Gulyas Sandor Jr.
Published: September 2022

Lake Pannon covered the area of the Pannonian Basin during the late Miocene. According to the seismic profiles, prograding deltas from the NW and NE resulted in the S-SE migration of the northern palaeoshoreline and the gradual aggradation of the lacustrine basin. The molluscan fauna living in the lake underwent a very rapid evolution. For the younger species, the possibilities of spreading became more and more restricted due to the gradual shoaling of the lake. The bivalve species Congeria rhomboidea M. HÖRNES occurs widely in the Upper Pannonian (Pontian sensu Stevanovic) deposits of Hungary and the neighbouring countries. Its evolution is relatively well understood. According to magnetostratigraphic data this species appeared in the lake 8.5 mya. According to the maximal geographical distributions of C. rhomboidea and its ancestor Congeria praerhomboidea STEVANOVIC occurring in sublittoral clay and silt along with the representatives of Prosodacnomya coming from littoral and lagoon deposits of the same age the estimated water coverage was around 75,000 km2 at the time of first emergence of C. rhomboidea in the lake. In the north the distribution of C. praerhomboidea is strictly restricted to the north of that of C. rhomboidea, its descendent, implying a clear S-SE trend in the migration of the lake’s northern palaeoshoreline. Distributions of the littoral Prosodacnomyas in relation to the sublittoral C. rhomboidea of the same age display a similar pattern. Meanwhile the western and southern palaeoshorelines underwent only minor fluctuations.
Geochemical Baseline Mapping of Soils Developed on Diverse Bedrock from Two Regions in Croatia

The comparison of contents and distribution maps for Al, As, Ba, Ca, Co, Cr, Cu, Fe, La, K, Na, Ni, Mg, Mn, P, Pb, Sc, Sr, Ti, Th, V, Y, Zn and Hg in the topsoil cover of two typical regions are given. One is a carbonate bedrock (karst) dominated region (southern Dalmatia) and the other a non-carbonate bedrock dominated region (NW Croatia). The results imply that the soils developed on carbonate bedrock have higher mean values of almost all elements excluding K, Na, Mg and Ba, which are lower in carbonate terrains. In comparison with the non-carbonate terrains, for the carbonate terrains the following elements have higher mean concentrations: Al, As, Co, Cu, Fe, La, Mn, Pb, Ni, Mn, Th, V, Cr, Zn, Zr and Nb, while Sr, P and Ti have similar contents. Approximately 4% of the sites can be considered as moderately enriched (polluted) in Pb, either from mining activities or airborne deposition. Only a limited number of sampling sites can be directly linked with mineralization. The derived factors are usually interpreted as associations of elements that imply a common source or behavior in regard to geogenic or anthropogenic influences. It was found that difference between the northwestern Croatia and southern Dalmatia is not expressed only by concentration differences but also by element associations. Five factor models accounting most of the data variability seemed appropriate to portray the geochemical variability within the topsoil of both regions.
Geochemical Comparison of Stream and Overbank Sediments: A Case Study from the Žumberak Region, Croatia
Authors:   Croatian Geological Survey, Zagreb, Croatia, Peh Zoran , Miko Slobodan ,   Croatian Geological Survey, Zagreb, Croatia
Published: September 2022

Geochemical comparison between the stream and overbank sediments from low- to medium-order drainage basins is grounded on the presupposed statistical contradistinction of their locality-paired sample correlatives. Discriminant analysis differentiated the overbank from stream material mainly on account of higher content of most of the analyzed elements in the former vis-a-vis an otherwise common geochemical semblance. Only the carbonate material seems to be depleted in overbank sediment samples. Investigations also demonstrated that in the relatively non-contaminated area it may be more difficult to verify the supposed purity-contamination reciprocity between the investigated media, since the recent and prehistoric materials were not contrasted as regards their non-lithogenic components.
Lower and Middle Liassic Calcareous Algae (Dasycladales) from Mt. Velebit (Croatia) and Mt. Trnovski Gozd (Slovenia) with Particular Reference to the Genus Palaeodasycladus (PIA, 1920) 1927 and Its Species
Authors:   Croatian Geological Survey, Zagreb, Croatia, Sokač Branko
Published: September 2022

Based on the characteristics of individual species, the generic characteristics of Palaeodasycladus have been determined and enlarged. P. mediterraneus (PIA, 1920) 1927 comprises a broad array of varieties that have been taxonomically distinguished on the basis of the variable shape of primary and secondary branches and the way in which the secondaries emerge. The following varieties are represented: P. mediterraneus (PIA, 1920) 1927 var. mediterraneus, P. mediterraneus var. heraki (SOKAC & NIKLER, 1966) n. comb., P. mediterraneus var. illyricus (SOKAC & NIKLER, 1966) n. comb., P. mediterraneus var. gracilis (CROS & LEMOINE, 1967 ex GRANIER & DELOFFRE, 1993) n. stat., P. mediterraneus var. elongatulus PRATURLON, 1966, and P. mediterraneus var. calciticus n. var., and are characterised by specific skeletal form and easily recognisable calcification pattern. Also, the generic assignment of P. barrabei LEBOUCHÉ & LEMOINE, 1963 ex GRANIER & DELOFFRE, 1993 has been confirmed, in spite of its recent transferral to Eodasycladus by BARATTOLO et al. (1994). The following new species have been described: Palaeodasycladus alanensis n. sp., characterised by broadened, bowl-shaped or bushy swollen primary branches; P. multiporus n. sp., characterised by numerous higher-order branches on each primary branch; P. benceki n. sp., with very large primary branches with extremely variable distal ends; and P. asteriscus n. sp., with loosely spaced whorls and variously directed secondary branches, often growing in opposite directions from the same primary branch. Lower Liassic species, previously ascribed to Fanesella, F. dolomitica and F. anae, have also been assigned to Palaeodasycladus with enlarged generic characteristics and are named, consequently, Palaeodasycladus dolomiticus (CROS & LEMOINE, 1966) n. comb. and P. anae (SOKAC, 1988) n. comb., respectively. Fanesella sokaci BARATTOLO & BIGOZZI, 1996 is considered to be a younger synonym of P. dolomiticus. Phylogenetic relationships between various taxa have also been considered and a phyletic lineage P. barrabei - P. alanensis - P. benceki has been shown to exist. As regards the relationship between Palaeodasycladus and Eodasycladus, the latter has been shown to have evolved directly from P. barrabei by enlarged and more pronounced bubble-shaped swelling of one of the secondary branches, which thus becomes a “sporangia-bearing” organ. Also, a new species tentatively assigned to the genus Selliporella, Selliporella? problematica n. sp., has been described. From its morphological characteristics it represents an intermediate form, and a phylogenetic link between Liassic Palaeodasycladus and Middle Jurassic Selliporella. Finally, a new species, Humiella japodica n. sp. has been described, thereby enlarging the stratigraphic range of the genus Humiella into the Lower Liassic.
Tower-type bounds for Roth’s theorem with popular differences
Authors: Fox Jacob , Pham Huy Tuan , Zhao Yufei
Published: September 2022

Green developed an arithmetic regularity lemma to prove a strengthening of Roth's theorem on arithmetic progressions in dense sets. It states that for every

\epsilon > 0

there is some

N_0(\epsilon)

such that for every

N \ge N_0(\epsilon)

and

A \subset [N]

with

|A| = \alpha N

, there is some nonzero

d

such that

A

contains at least

(\alpha^3 - \epsilon) N

three-term arithmetic progressions with common difference

d

.

We prove that the minimum

N_0(\epsilon)

in Green's theorem is an exponential tower of twos of height on the order of

\log(1/\epsilon)

. Both the lower and upper bounds are new. This shows that the tower-type bounds that arise from the use of a regularity lemma in this application are quantitatively necessary.
Non-locality, non-linearity, and existence of solutions to the Dirichlet problem for least gradient functions in metric measure spaces
Authors: Kline Josh
Published: September 2022

We study the Dirichlet problem for least gradient functions for domains in metric spaces equipped with a doubling measure and supporting a (1,1)-Poincaré inequality when the boundary of the domain satisfies a positive mean curvature condition. In this setting, it was shown by Malý, Lahti, Shanmugalingam, and Speight (2019) that solutions exist for continuous boundary data. We extend these results, showing existence of solutions for boundary data that are approximable from above and below by continuous functions. We also show that for each

f\in L^1(\partial\Omega)

, there is a least gradient function in

\Omega

whose trace agrees with

f

at all points of continuity of

f

, and so we obtain existence of solutions for boundary data which are continuous almost everywhere. This is in contrast to a result of Spradlin and Tamasan (2014), who constructed an

L^1

-function on the unit circle which has no least gradient solution in the unit disk in

\mathbb{R}^2

. Modifying the example of Spradlin and Tamasan, we show that the space of solvable

L^1

-functions on the unit circle is non-linear, even though the unit disk satisfies the positive mean curvature condition.
Neolithic Settlement Structures in Central Europe
Authors: Trampota František , Pajdla Petr
Published: September 2022

The study examines the degree of similarity of Neolithic settlement structures in two geographically separated regions (eastern half of Bohemia, Morava River Basin) based on the analysis of 11 variables related to the environment and the settlement structures. The period studied corresponds to c. 4900–3400 BC. Although the results of most of the variables analysed using principal component analysis (PCA) do not show significant differences in the preference of settlement locations, the analysis of the individual variables points very clearly to major differences in settlement patterns. These are manifested in different settlement dynamics, accessibility to stone raw materials, and the spatial extent of occupation. The general conclusion is that although early agricultural societies are similar in general terms regarding the location of settlements, their individual aspects are quite different, which must have been reflected in lifestyles during the Neolithic.
Geriatrik Köpeklerde Fizyoterapi ve Rehabilitasyon: Güncel Bakış
Authors: ALTINKAYA Neyran
Published: September 2022

Geriatrik ve artritik köpeklerin durumlarına özel rehabilitasyona ihtiyaçları vardır. Yaşlanan köpeklerde ilerleyici hareket kaybıyla bağlantılı olarak fonksiyonel durum kötüleşir. Yaşlanma, çok çeşitli dokularda değişikliklere neden olur. Ayrıca yaşlanan köpeklerde kronik hastalıkların görülme sıklığı ve şiddeti de artmaktadır. Öngörülen yaşam süresinin %75’ine ulaşan hayvanlar geriatrik olarak tanımlanır. Yaşlanma süreci cins, genetik, beslenme, çevre ve diğer faktörlerden etkilenir. Veteriner hekimlikte tıbbi ve cerrahi ilerlemeler nedeniyle köpeklerin yaşam süresi uzamıştır. Bunun bir sonucu olarak, evcil hayvanların sahipleri yaşlılığa bağlı bir dizi sorunla karşı karşıya kalmaktadır. Pek çok evcil hayvan ergenlik çağında aktif olsa da, çoğu köpek 6 yaşından itibaren yaşlanma belirtileri göstermeye başlar. Bu durumdaki geriatrik köpekler kapsamlı bir değerlendirmeye ve rehabilitasyona ihtiyaç duyar. Geriatrik ve artritik köpekler, durumlarındaki değişiklikleri tespit edebilmek ve en doğru bakım planını tasarlayabilmek için mutlaka düzenli olarak değerlendirilmelidir. Geriatrik köpeklerde sıklıkla ağrı ve hareket kısıtlılığı görülür, yaşam kalitesi azalır. Ağrı yönetimi kılavuzlarının, multimodal ilaçların, fiziksel rehabilitasyon modalitelerinin ve çevresel düzenlemelerin kullanılması yaşlı köpeğin kaliteli bir yaşam sürmesini sağlar. Yaşlanan köpekler için rehabilitasyon hedefleri, sağlığı desteklemeyi, yaşa bağlı sağlık sorunlarının ilerlemesini yavaşlatmayı ve köpeğin yaşam kalitesini arttırmayı ve -mümkünse- yaşam süresini uzatmayı içerir. Bu çalışmada yaşlanmanın etkileri, yaşlanan köpekte yaygın görülen kas-iskelet sistemi değişiklikleri, yaşam kalitesi, ağrı yönetimi ve artritik köpeğin rehabilitasyon süreci üzerinde durulmaktadır.

Purpose: The purpose of this paper is to analyze the current status and trends of the Japanese insurance industryand derive implications for Korean insurance industry. The Japanese insurance industry is divided into two marketssuch as life and non-life insurance to review the current status and trends of each market such as premiums,products, channels, and companies, and regulations. And major issues and environmental trends of the Japaneseinsurance industry are analyzed to derive lessons for domestic insurance industry.
Research design, data, and methodology: We adopted a case study method utilizing statistical data analysis andliterature review to analyze Japanese insurance Industry such as premiums, products, channels, and companies. Andmajor issues and environmental trends of the Japanese insurance industry are also analyzed to compare domesticinsurance industry. We combined the research experiences, ideas, and wisdom of wide rane of insurance literatures.
Results: This research results are as follows. First, Japanese insurance industry has develped various new products inresponse to customer demand changes. Second, Japanese insurers have tried to seek gloal strategy to expand theirprofit and market share. Third, new management strategies such as product development, new profit area diversity,overseas expansion, should be taken into account in order to systematically respond to social changes.
Implications: The insurance industry in Japan has shown interesting phenomena since 1995 such as population agingand bubble collision. They have affected insurance demands in several ways. To respond these changes Japansesinsurers strategies such as product development, sales channels diversity, overseas expansion should be taken intoaccount in order to systematically respond to social, economic, regulatory changes, especially population aging. Domestic insurance industry must be also modified and redesigned to meet new market changes and trends.

Authors:   The Korean-Japanese Economics & Management Association, Yu Jae-Seon
Published: September 2022

Purpose: The purpose of this paper is to analyze the trade structure and in terms of quality competitiveness of Koreaand Japan’s Information and communications technology(ICT) industry in comparison to that of China.
Research design, data, and methodology: Indices such as Revealed Comparative Advantage(RCA) and RevealedSymmetric Comparative Advantage Index(RSCA) are used. Further, an Intra-Industry Trade (IIT) index is used to analyzequalitative changes in Intra-Industry trade of horizontal intra-industry trade, high-quality vertical items and low-qualityvertical items.
Results: An analysis of export competitiveness through RSCA analysis showed that the Korean and Japanese ICTindustry’s competitiveness against China is strong, and its competitiveness is gradually improving. By classification, firstof all, in the case of Korea, it was found that parts, broadcasting apparatus, information apparatus, and communicationapparatus were in the order of competitiveness. In addition, the change in competitiveness in 2019 compared to2010 showed that the competitiveness of communication apparatus and information apparatus improved, but thecompetitiveness of broadcasting apparatus and parts weakened. In the case of Japan, the competitiveness of parts,broadcasting apparatus, and communication apparatus was found to be strong, but the competitiveness ofinformation apparatus was weak as they continued to show comparative inferiority. The change in competitiveness in2019 compared to 2010 showed that the competitiveness of information apparatus, communication apparatus, andparts improved, while only broadcasting apparatus weakened.
Implications: This study has academic and political implications because it analyzes the changes in ICT tradecompetitiveness between Korea and Japan. However, there is a limitation of this study in that it did not considertrade competitiveness in terms of imports and the factors that determine trade.

Purpose: This study aims to investigate the relative importance of ESG evaluation factors of social enterprises byapplying ESG evaluation factors to social enterprises in securing local social values. In previous studies, ESG-relatedevaluations of various industries are being conducted, and ESG evaluation is becoming important for mid-sized andsmall-sized companies in the future, so it is a task to be performed. This study is a study on the relative determinantsof evaluation factors to determine ESG evaluation factors of social enterprises.
Research design, data, and methodology: Lack of unified guidelines, there are confusions in evaluation of ESG institutionsresults may are in evaluation of the same corporate due to differences in evaluation factors and methods. This has anegative effect on a company’s ESG evaluation. Fortunately, the government set up K-ESG guidelines in December2021. In this study, most of the social enterprises were in the form of SMEs, Thus the evaluation factors of K-ESGsmall and medium-sized enterprises were applied, and the Social Value Index (SVI) of the Social Enterprise PromotionAgency was used. The survey area and subjects were surveyed through a survey of related entrepreneurs and expertsof social enterprises in Gangwon-do, and the AHP analysis method was used to find out the relative importance offactors.
Results: The conclusion of this study is as follows. First, specific systematization was realized by approaching the ESGevaluation criteria of social enterprises at the hierarchical level of the Triple Bottom Line (TBL). Second, the ESGevaluation criteria of social enterprises with social value as their management goals were quantified through AHPanalysis, and importance ranking were determined. Third, ESG evaluation criteria were established and presentedthrough analysis by experts in the field of social enterprises.
Implications: ESG demands due to the importance of continuous management will also affect social enterprises, and astrategic system is needed to establish and promote social value-based evaluation standards pursued by socialenterprises through the establishment of ESG evaluation standards.
