Critical Differences in the Treatment of Depressive Symptoms in Narcissistic and Depressive Personalities
Authors: Malone Brady , Huprich Steven
Published: April 2021

In reviewing descriptions of depressive and vulnerably narcissistic personalities, it might appear as if the same condition is being described. The authors briefly review the depressive and narcissistic personality constructs, highlighting the similarities in the two, but also identifying critical differences in how the conditions are manifested. By illustration of two case vignettes and identifying primary symptomatic distinctions, the authors describe the differences in conceptualizing and treating depressive symptoms in depressive and narcissistic personalities. Important distinctions in the roles of perfectionism and living up to idealized expectations are explained, as well as how to understand the role of what appears to be grandiosity. We conclude that while depressive symptoms develop similarly in narcissistic and depressive personalities, the critical distinctions between these organizations outlined in this paper call for divergent treatment approaches. Specially, treatment of depressive symptoms in depressive personalities should involve exploring the client’s disavowed needs and offering appropriate encouragement, while treating narcissistic personalities should focus on the integration of split-off object representations through, in part, challenging their grandiose strivings. Failure to disentangle narcissistic from depressive personalities can lead to counterproductive client internalizations and therefore splitting the categories as we suggest may lead to enhanced clinical utility.
Enhancing HIV Prevention Services: Exploring Psychosocial Associations of HIV Antibody Testing Frequency among Sexually Active Men who have Sex with Men
Authors: Sabato Todd
Published: April 2021

Despite recommendations of annual HIV testing for high-risk individuals, one-third of infected men who have sex with men (MSM) are unaware of their serostatus. In an effort to improve HIV prevention services and subsequently decrease prevalence, this study aimed to examine the HIV testing patterns and factors associated with testing frequency among MSM. Utilizing eight reliable and validated instruments and a sample of 374 sexually active MSM, this study examined a series of demographic, behavioral and psychosocial associations of antibody testing frequency, including substance use/abuse, depression levels, internalized homophobia, unprotected anal intercourse, sexual regulation and attribution, and HIV knowledge, . MSM who tested for HIV frequently were more likely to be older, have higher levels of educational attainment, and self-identify as gay. Respondents who reported never having been tested and irregularly tested had higher levels of internalized homophobia, depression, and alcohol use and abuse patterns. Respondents who had never been tested or infrequently tested engaged in lower levels of sexual risk, particularly unprotected receptive anal intercourse. Those with no or irregular histories of testing also exhibited greater external sexual loci of control, and were significantly more likely to attribute life events to external, unstable, and pessimistic causes.
Black Bile, Manic Depression and Melancholy: Two Pillars of Our Understanding
Authors: Tipton Jason
Published: April 2021

I aim to demonstrate the movement of the argument of the Aristotelian Problem XXX.1 as it illuminates the phenomena of melancholy, which it is argued is more rightly understood as manic depression, and black bile. The discussion will aid contemporary researchers in psychiatry as well as those in ancient philosophy and medicine. An appeal to both Emil Kraeplin and the Aristotelian author will demonstrate surprising resonances. An appeal to Aristotle’s discussion of anger in the De Anima will make clearer what is at stake in Problem XXX.1.
Ontogenes and the genetics of intraspecific similarity
Authors: Chadov B. F. , Fedorova N. B.
Published: April 2021

The experiments by Gregor Mendel, which formed the background for genetics, were performed with the characters of intraspecific difference (alternative characters). Mendelian protein-coding genes are responsible for these characters. Until recently, these genes were regarded as the only and main hereditary factors responsible for ontogenesis and phylogenesis. The review outlines the information about another category of biological characters (the characters of intraspecific similarity) and, correspondingly, of a special category of genes responsible for these characters (ontogenes). The study into mutations of ontogenes in drosophila experiments suggests that (1) ontogenes control the construction of cell ensembles and trigger protein-coding genes in cells; (2) the program of individual development is encoded in ontogenes and “edited” in germline cells; (3) ontogenes fulfill a regulatory function without any contacts and chemical intermediaries, which suggests a kind of biophysical activity; and (4) two categories of cells—stem cells and terminally differentiated cells—correspond to these two categories of genes. Ontogenes are active in stem cells and protein-coding genes, in terminally differentiated cells.
COVID-19 Attributed Cases and Deaths are Statistically Higher in States and Counties with 5th Generation Millimeter Wave Wireless Telecommunications in the United States.
Authors: tsiang angela , Havas Magda
Published: April 2021

COVID-19-attributed case and death rates for the U.S.A. were analyzed through May 2020 in three ways – for all 50 states, the country’s largest counties, and the largest counties in California – and found to be statistically significantly higher for states and counties with compared to those without 5G millimeter wave (mmW) technology. 5G mmW index was a statistically significant factor for the higher case and rates in all three analyses, while population density, air quality and latitude were significant for only one or two of the analyses. For state averages, cases per million were 79% higher (p = 0.012), deaths per million were 94% higher (p = 0.049), cases per test were 68% higher (p = 0.003) and deaths per test were 81% higher (p = 0.025) for states with vs. without mmW. For county averages, cases per million were 87% higher (p = 0.005) and deaths per million were 165% higher (p = 0.012) for counties with vs. without mmW. While higher population density contributed to the higher mean case and death rates in the mmW states and counties, exposure to mmW had about the same impact as higher density of mmW states on mean case and death rates and about three times as much impact as higher density for mmW counties on mean case and death rates. Based on multiple linear regression, if there was no mmW exposure, case and death rates would be 18-30% lower for 5G mmW states and 39-57% lower for 5G mmW counties. This assessment clearly shows exposure to 5G mmW technology is statistically significantly associated with higher COVID-19 case and death rates in the U.S.A. The mechanism–should this be a causal relationship–may relate to changes in blood chemistry, oxidative stress, an impaired immune response, an altered cardiovascular and/or neurological response.
Age and Cervical Cancer Screening Recommendations
Authors: Levine Elliot , Ginsberg Norman , Fernandez Carlos
Published: April 2021

Recommendations for cervical cancer screening have had remarkable agreement from a number of medical societies, including the American College of Obstetricians and Gynecologists (ACOG), American Cancer Society (ACS), American Society of Cervical Colposcopy and Pathology (ASCCP), and the US Preventative Services Task Force (USPSTF). Reference to the recommended age for screening may need to be re-examined, in light of current data regarding the comparative age-related incidence of cervical malignancy, especially when recognizing the past utility of screening with exfoliative cytology in reducing subsequent mortality.
Social and Economic Needs of the Not Pertinent Demand by the Mobile Emergency Service in Porto Alegre, RS, Brazil
Authors: Veronese Andréa
Published: April 2021

The purpose of the article is to present a part of the demand study to the Porto Alegre, Brazil Mobile Emergency Service (SAMU) considered not pertinent (NPD) by the service. This not pertinence is established when the case is not configured, by the regulator physician, as death risk situation, being unnecessary, therefore, sending ambulances to attend. The research occurred in two stages. At first, was accomplish an analysis of telephone calls at SAMU in 2009. These data were analyzed using the Statistical Package for the Social Sciences. In second stage, 31 applicants from de NPD were interviewed following the premises of Grounded Theory. Among the results, it is highlighted that, in 2009, the NPD to SAMU of Porto Alegre represented 33,2% (26.233) of calls directed to 192. In qualitative analysis, factors were described that influenced people to request ambulances. The results pointed out that the demand is the result of a complex process of interaction between those who ask for help and the resources they have / use to solve their problems. In other words, a call for ambulance is not just a health problem. The call for help involves social needs, economic need, divergences with health professionals in the meanings of what is risk of death, lack of notion of first aid and access problems for the treatment of health problems. Therefore, service regulation needs to be careful when listening for help. The patients often have needs that go beyond the focus of the service. The ambulance nursing, in turn, needs to be prepared to meet this NPD. The study showed that urgent health problems are not exclusive to the health sector. The complexity of health emergencies also has implications for the sectors of education, health promotion, social assistance, security, construction and infrastructure, transport, among others. Such findings reinforce the need for user-centered assistance, thus reducing the difficulties in coping with their health problems and justifying inter-sectoral actions that may be proposed based on this research. The study was approved by the ethic and research committee of the Municipal Health Department of the city hall of Porto Alegre.
Acute Hypoxic Respiratory Failure /Hyperammonemic encephalopathy in the setting of concurrent use of valproic acid and topiramate
Authors: Zeid Fuad , Raru Yonas
Published: April 2021

Valproic acid (VPA) is widely used for the treatment of epilepsy, migraine, and a variety of psychiatric symptoms, including bipolar disorder, borderline personality disorder, and alcohol withdrawal. Valproate is associated with severe idiosyncratic adverse effects, the most notable being valproate-induced hyperammonemic encephalopathy (VHE). Topiramate is also a broad-spectrum anticonvulsant that is also extensively used for migraine prophylaxis, as a mood stabilizer, and for alcohol dependency. There is increased occurrence of VHE when valproate is used with other medications like phenytoin, phenobarbital, and topiramate. We report a young patient who was on valproic acid and topiramate and developed metabolic encephalopathy with hypoxic respiratory failure with review of the causes and management of the hyperammonemic encephalopathy. We believe that clinicians should be aware of possible hyperammonemic encephalopathy in any patient who is taking valproic acid and presenting with impaired consciousness and cognitive decline. We also underline the importance of early recognition and high index of suspicion of encephalopathy related to hyperammonemia.

Previous report shows relationship between C. pneumonie and Asthma. In this study, we assessed the association between exposure to C. pneumoniae infection and the risk of bronchial asthma in adolescents in the State of Morelos, Mexico. An analysis was performed on a population-based cohort study of 80 adolescents with respiratory symptoms of asthma defined by ISAAC and 202 healthy adolescents between 12 and 17 years old. The information was collected twice from questionnaires, anthropometry, and sampling. Excessive weight gain was determined by calculating body mass index, and exposure to the specific antibodies IgM, IgG, and IgA was detected by microimmunofluorescence. The geometric means were calculated for titers of C. pneumoniae. The odds ratio was used across multiple models. The results showed that the exposure to C. pneumoniae was very high in the study population (67.2%). All immunoglobulins were significantly increased in patients with asthma symptoms compared with the healthy population (17% for IgG, 34% for IgM, and 52% for IgA). In multiple models, the IgM and IgA immunoglobulins were found to be associated with asthma (OR, 2.4; 95% CI, 1.4–4.2 and OR, 2.4; 95% CI, 1.2–4.8, respectively). Our study reflects a high seroprevalence of C. pneumoniae in the population; this seroprevalence is higher in young people with asthma. Specific immunoglobulins to C. pneumoniae are associated with IgM and IgA. The epidemiological significance of our results influences the timely monitoring and management of infections acquired at an early age that persist, or recur, for much of the juvenile life. Additional studies are needed to validate our findings.
Time-course of adaptations for electroretinography and pupillography
Authors: Asakawa Ken
Published: April 2021

Cones are primarily involved in photopic vision and light adaptation. Rods are responsible for scotopic vision and dark adaptation. The typical time-courses of light and dark adaptations have been known for century. However, information regarding the minimal adaptation time for electroretinography (ERG) and pupillography would be helpful for practical applications and clinical efficiency. Therefore, we investigated the relationship between adaptation time and the parameters of ERG and pupillography. Forty-six eyes of 23 healthy women (mean age, 21.7 years) were enrolled. ERG and pupillography were tested for right and left eyes, respectively. ERG with a skin electrode was used to determine amplitude (µV) and implicit time (msec) by the records of rod-, flash-, cone-, and flicker-responses with white light (0.01–30 cd·s/m2). Infrared pupillography was used to record the pupillary response to 1-sec stimulation of red light (100 cd/m2). Cone- and flicker- (rod-, flash-, and pupil) responses were recorded after light (dark) adaptation at 1, 5, 10, 15, and 20 min. Amplitude was significantly different between 1 min and ≥5 or ≥10 min after adaptation in b-wave of cone- or rod-response, respectively. Implicit time differed significantly between 1 min and ≥5 min after adaptation with b-wave of cone- and rod-response. There were significant differences between 1 min and ≥10 or ≥5 min after dark adaptation in parameter of minimum pupil diameter or constriction rate, respectively. Consequently, light-adapted ERGs can be recorded, even in 5 min of light adaptation time without special light condition, whereas dark-adapted ERGs and pupillary response results can be obtained in 10 min or longer of dark adaptation time in complete darkness.

Authors: Bernardino Silvya , Morais de Souza Fernando , Martins Roberto , Lêdo de Araújo Mariana , Malheiros Rodrigo , Bernardino de Souza Isabel , Bernardino de Souza Regina
Published: April 2021

Background: Cervical schwannoma is a rare and benign tumor exclusively developed from the cell of Schwann that rarely involve the vagus nerve. Methods: We have conducted a retrospective review with strategy of the consulted references and database included articles published in Portuguese, English and French in PUBMED, MEDLINE, EMBASE, LILACS and SciELO, since 1936 until the present day, associated with a description of two illustrative cases. Both patients presented with a history of painless palpable mass in the cervical region. Results: About 160 cases has been described in literature. Most cases of manifest between the third and sixth decades of the patient's life as a slow growing firm, painless mass in the lateral neck. Imaging is essential to management. Histopathological examination can reveals encapsulated, biphasic spindle cell neoplasia. The best choice of treatment for this type of tumor is complete surgical removal with preservation of the vagus nerve by means of intracapsular resection. In both ilustrative cases the lesions were diagnosed by means of imaging studies and were totally ressected. Surgical findings and histopathology confirmed the diagnosis of vagus nerve schwannoma. There was no recurrence at five years of follow-up. In one case there was disphonya that solved within six months after the surgery. Conclusion: Vagus nerve schwannomas are rare benign tumors. The enucleation technique is used to obtain the most functional preservation and complete excision without permanent deficit is possible even with the occurrence of large lesions.
Catecholamine Concentrations during and after Retroperitoneoscopic Adrenalectomies in Surgeon, Anaesthetist and Patients – how is physiological stress different from pathophysiological stress?
Authors: Groeben Harald , Schulze Laura , Brunkhorst Violeta , Alesina Piero , Walz Martin
Published: April 2021

Background: During resections of phaeochromocytoma release of catecholamines can lead to excessive hypertension and arrhythmia. Therefore, these procedures can be stressful to surgeons and anaesthetists. It is completely unknown, how the excessive catecholamine concentrations in phaeochromocytoma patients relate to catecholamine concentrations of physiological stress of physicians and control patients undergoing adrenalectomy because of hormone inactive tumours. We measured catecholamine concentrations, heart rate and blood pressure in patients with phaeochromocytoma, incidentaloma, a surgeon and an anaesthetist. Methods: After approval of the local ethics committee, we measured metanephrine and normetanephrine plasma concentrations in 8 patients with phaeochromocytoma, 6 control patients with incidentaloma, one surgeon and one anaesthetist at rest, after incision, after 20 and 40 minutes of surgery, and in recovery. Moreover, blood pressure and heart rate were obtained. Results: Intraoperatively significant increases of blood pressure, metanephrine and normetanephrine were found in patients and surgeon. Significant increase of normetanephrine was also found in control patients. But catecholamine concentrations in patients with phaeochromocytoma were 18 to 42 times higher than in control patients and physicians. Heart rate analysis showed no significant results. Conclusion: During phaeochromocytoma resections significant increases in catecholamine concentration and blood pressure can be found in patients and physicians. The excessive increase of catecholamine concentrations in phaeochromocytoma patients, was not always reflected by a corresponding blood pressure increase. Interestingly, although catecholamine concentrations in phaeochromocytoma patients almost normalize directly after surgery, their blood pressure remains stable without the need for pharmacological support.

Published: April 2021

This paper examines a cross-sector collaborative model for development policy in a creative economy in a rural area setting. The creative economy based on the village’s creative potential is considered capable of contributing to the national economy, but it should be supported by public policies that are adaptive to the potential and needs of creative economy actors. The paper used a qualitative approach with case studies in Banyumas Regency, Central Java, Indonesia. This village represents one of the leading creative economy subsectors in Indonesia, which is culinary. The study found that collaboration among Penta Helix forces played multiple roles in driving rural creative actors and building rural creative ecosystems. The stages of collaboration were identified in strengthening organizational structure, program implementation, and organizational consolidation.  Organizational capability and innovation have been growing in rural creative economy actors during cross-sector collaboration implementation. This study provides insights into how Penta Helix collaborates with rural creative actors to promote the rural creative economy. From a public policy perspective, this study fills a significant gap in the literature regarding rural development models that are not covered much in the creative economy policy.

Published: April 2021

The COVID-19 Pandemic has struck many countries, including Indonesia. The Indonesian government has created and implemented various policies in dealing with this epidemic, from the central government to the villages. The COVID-19 pandemic response at the local level is regulated in a Village Minister Circular Number 8 of 2020. In tackling the outbreak at the village level, leadership that can embrace all stakeholders is required. This study examines further the collaborative leadership of Wali Nagari in mitigating the COVID-19 pandemic in Nagari Rancak in West Sumatra Province. The research approach used was qualitative with descriptive analysis. The research was conducted in five villages in West Sumatra Province. Data collection techniques in the form of interviews and documentation. This study concluded that the three Nagari Rancak, namely Nagari Batu Bulek, Nagari Sungayang, and Nagari Pakan Sinayan, did not apply collaborative leadership to the maximum, while the other two Nagaris, namely the Nyalo IV Koto Mudiek River Village and the Taram Nagari, had implemented a collaborative leadership model. With collaborative leadership, the Nagari’s Wali (leaders) could cover the limitations to overcome COVID-19 impacts in the village.

Published: April 2021

The discussion on the power relationship between the state and adat or customs is always exciting because although adat is most likely getting tension from the state through various regulations, it keeps signifying its existence. An interesting phenomenon that happened after the downfall of the New Order regime and the expansion of the Regional Autonomy System’s implementation was adat power’s reappearance at the local level. For instance, Adat Functionary in the Kerinci Regency signified their dominance over the village government. The studies about the relationship between adat and the state tend to put adat as an identity and spirit for gaining support, power, and fund also tools to deal with the government. This study begins with the fact that adat is dominant over the village government in decision-making. This study found in the Kerinci regency obtained a new government structure by the returning of adat power in governance, and affected the stability of the village administration, also used it as the solidarity mechanism of the community in Kerinci Regency to resolve various conflicts. Thus, the meaning of domination, which is commonly interpreted as something negative, is turning out to be a contrary one since it makes the community more solid through adat.
Advocacy Coalition in The Arrangement of The Coastal Slum Area of Untia in Makassar
Authors: Rusnaedy Zaldi , Haris Almuhajir
Published: April 2021

The arrangement of the slum settlement area is still a problem faced by the Makassar City Government. There are 740.10 hectares of slum areas in Makassar City, one of which is the Untia coast. This study aimed to analyze the advocacy coalition in slum area management. The research method used was a qualitative method. The results showed that at the beginning of 2019, Untia had become a light slum area from the previous heavy slum. This happened because Untia received many programs from the government for a relatively long time. This activity was a collaborative activity of several government institutions and Kotaku government agencies that are members of the Working Group (Pokja). Therefore, Untia is still in the category of a slum area, not because of a lack of assistance from the government, but rather because the programs implemented are not integrated. So, the result was that the settlements that receive the program only come out of the slum indicator partially. In addition, the institutions involved in the Working Group (Pokja) often overlap programs due to a lack of face-to-face communications.
AMMI and GGE Biplot Analysis of Seed Yield and Batter Quality Traits in Blackgram [Vigna mungo (L.) Hepper]
Authors: Rajalakshmi K. , Manivannan N. , Anand G. , Vanniarajan C. , Harish S.
Published: April 2021

Background: Blackgram is an important pulse crop consumed in the form of fermented cuisines especially in south India. Yield being a complex trait, is highly influenced by environment. Studies on environmental influence on batter quality are rare. Hence, the current study was taken up to identity stable genotypes over environments with respect to yield and batter quality traits. Methods: In the present study, 32 blackgram genotypes were evaluated for yield performance and batter quality traits during kharif 2019, rabi 2019-20 and summer 2020 at National Pulses Research Centre, Vamban. Pooled analysis of variance and stability analysis was performed by AMMI and GGE biplot. Result: From stability analysis, it was evident that the genotypes, ACM BG 17-001, ACM BG 17-006 and ACM BG 18-010 expressed high mean value and stability for seed yield. In case of idly batter volume, the genotypes, ACM BG 17-001 was stable hence may be recommended for all season cultivation. The trait, vada batter volume was found to be with non-significant GxE interaction and hence do not interact with the environment. Among the environments under study, summer season was the most favourable environment for seed yield. However, for idly batter quality, kharif season was the most favourable environment.

Published: April 2021

Background: Clusterbean [Cyamopsis tetragonoloba (L.) Taub.] (2n=2x=14) is an under exploited legume belonging to the family Fabaceae. Clusterbean is a versatile legume crop cultivated mostly as vegetable, for the extraction of guar gum, animal feed cover crop. Clusterbean is a drought tolerant, hardy, deep rooted annual legume. To assess the nature and magnitude for genetic variability, heritability and genetic advance for seed yield and component characters that are useful for an effective selection programme, the present study was under taken. Methods: A set of 40 clusterbean genotypes were evaluated during Kharif 2019 in in randomized complete block design with four replications at Agronomy Instructional Farm, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, Gujarat, India. Result: The highest estimates of genotypic coefficient of variation was observed for the number of branches per plant followed by seed yield per plant, days to flowering and number of clusters per plant indicating the presence of wide genetic variability for these characters. High estimates of heritability coupled with high genetic advance were observed for number of branches per plant, seed yield per plant and days to flowering indicating the presence of additive genes and less environmental influence on the characters and existence of sufficient heritable variation and wider scope for effective selection.

Form Finding and Analysis of an Active Bending-Pantographic Bamboo Space Structure
Authors: Seixas Mario , Eustáquio Moreira Luís , Stoffel Patrick , Bina João
Published: April 2021

This paper presents the form finding and structural analysis of an active bending-pantographic bamboo space structure that integrates self-stressed active bending arches, tensile pantographic grids and supporting bipods. The structure was designed to roof an open-aired amphitheater
in the tropical climate. The structure has a self-supporting behavior and a mobile assembly procedure, applying the hinged flexible connection (HFC) mechanism. The structure was developed initially through small-scale physical models, then, on computer models and full-scale prototypes. Empirical
models were used to determine the minimum bending radius of the arches and served to embed data for the computer models. The active bending arch (ABA) applied Phyllostachys aurea bamboo rods subjected to axial loads up to the elastic limit of strain on the beams. Steel cables and diagonal
rods were connected to the curved beams, avoiding buckling in the plane of the arches. Modular pantographic grids were deployed over the ABA, generating double curved space frames with free- form geometries. The coupling of active bending arches and pantographic grids resulted in a hybrid
structure, with mutual operation of bending-active and form-active structural modules. The developed structure used bio-based materials for a sustainable engineering design, with lightweight techniques and low-carbon footprint.

Published: April 2021

Background:

Few investigations of venous tumor thrombus (VTT) in primary pelvic bone sarcomas are available. We aimed to identify the prevalence, associated factors, and prognosis of VTT across different types of pelvic sarcomas and to propose an algorithm for management.

Methods:

We included 451 consecutive cases of primary, bone-derived, treatment-naive, pelvic sarcomas in this study. Demographic data and the results of initial laboratory tests, imaging examinations, and oncological evaluations were extracted and analyzed. Forty-four cases of VTT were diagnosed with radiographic examinations, and 18 of them were verified histologically.

Results:

The cohort consisted of chondrosarcomas (41.2%), osteosarcomas (30.4%), Ewing sarcomas (15.5%), bone-derived undifferentiated pleomorphic sarcomas (5.8%), and other bone sarcomas (7.1%). The prevalence of VTT was 9.8% in the whole group, and associated factors included a lactate dehydrogenase (LDH) level of ≥230.5 U/L and invasion of the L5-S1 intervertebral foramen. Patients with pelvic osteosarcoma had a high prevalence of VTT (22.6%), and the associated factors in this group included a chondroblastic subtype, an LDH level of ≥187 U/L, and invasion of the obturator foramen and the L5-S1 intervertebral foramen. Patients with VTT had a poor prognosis with a median overall survival time of 14 months. Subgroup analyses of localized pelvic osteosarcoma indicated that the presence of VTT decreased the median overall survival time (21.5 versus 54.0 months for those without VTT, p = 0.003), median recurrence-free survival time (18.6 versus 32.4 months, p = 0.020), and median metastasis-free survival time (11.2 versus 41.0 months, p < 0.001).

Conclusions:

VTT is most common in patients with pelvic osteosarcoma as compared with patients with other primary bone sarcomas, and it is associated with several factors. It is a negative prognostic factor. An algorithm for management of pelvic sarcomas with VTT stratified by the classification of the VTT might be beneficial, but further validation is necessary.

COVID-19: Impact on Orthopaedic Graduate Medical Education in the U.S.
Authors: Van Heest Ann , Brandt Aaron M. , Dyer George , Homer Cole J. , Murray Peter M.
Published: April 2021

The COVID-19 crisis has challenged the U.S. health-care system in a variety of ways, including how we teach and train orthopaedic surgery residents and fellows. During the spring of 2020, the cessation of all elective surgical procedures and the diminished number of outpatient visits challenged graduate medical education. While residency programs in less affected areas may not have had to make many dramatic adjustments, some of those located in pandemic hotspots had to redirect trainees from orthopaedic rotations to COVID-19 units. No matter the region, the time that trainees have spent in rotations has been altered, and absences have occurred due to quarantines. This symposium summarizes the impact of restrictions related to the COVID-19 pandemic on residency and fellowship programs from the perspectives of the Accreditation Council for Graduate Medical Education (ACGME), a program director, and a graduating resident. Although new opportunities for virtual curricula, virtual surgical simulation, and virtual interviews have been innovated, residency programs and residents report primarily a negative effect from the pandemic due to decreased surgical volumes and the limitation of patient-care experiences. Ultimately, program directors have an obligation to the program, the trainee, and the general public to graduate only those residents and fellows who are truly prepared to practice independently; they have the responsibility of making the final decision regarding graduation. The COVID-19 pandemic has continued to underscore the need for competency-based medical education. Assessing competency includes evaluation of the knowledge, the operative skills, the nonoperative patient-care skills, and the professional behavior of each and every individual graduating from orthopaedic residency and fellowship training programs. A hybrid model for time and competency-based training, with established national standards not only for accreditation for our training programs but also for board certification of our graduating residents, was enhanced by the COVID-19 pandemic and is highlighted in this symposium.
Novel Graft Technique for Lumbopelvic Reconstruction After Sacral Tumor Resection
Authors: McLain Robert F.
Published: April 2021

Case:

Reconstruction after sacral tumor resection carries a high risk of nonunion and requires a slow return to weight-bearing. A bilateral iliac-crest graft, mobilized on a muscular pedicle, was used to graft and fuse the spine and pelvis after resection of a massive sacral schwannoma. Long-term follow-up and three-dimensional computed tomography imaging demonstrate rapid incorporation and solid fusion, with hypertrophy of the graft struts and excellent return to function.

Case:

We report a case of periprosthetic acetabular fracture with pelvic discontinuity (PAFPD) classified Paprosky IIIb around an infected hip resurfacing prosthesis. A 3-stage revision was performed with (1) implants removal and surgical debridement to treat the infection; (2) open reduction and internal fixation using a medial buttress plate to treat pelvic discontinuity; and (3) custom-made total hip replacement with acetabular-ring reinforcement. The patient recovered with excellent clinical and radiographic results at 4-year follow-up.

Conclusions:

In complex cases of PAFPD, a collaboration between pelvic trauma surgeons and orthopaedic hip surgeons allows to provide stability for revision surgeries with good outcomes.
Losartan
Authors: Hubbert Katherine , Clement Ryan
Published: April 2021

Skeletal muscle injury is a common and debilitating orthopaedic condition. Unfortunately, current treatment protocols inadequately facilitate full muscular recovery. New research is investigating modalities that regulate postinjury muscle fibrosis or scar tissue, which in excess can increase muscle stiffness and risk of reinjury. Losartan, a well-known angiotensin II receptor blocker, reduces muscle fibrosis after acute muscle injury in animal models by indirectly inhibiting transforming growth factor-β1, a profibrotic growth factor released during muscle healing. Although promising results have been shown thus far, additional human clinical trials are needed to confirm these findings and provide guidance on treatment.

Organic matter (OM) pores are widely considered to be important for gas storage and transportation. In this work, we quantitatively analyze the pore structure of OM and its controlling factors through geochemical and petrologic analyses, optical microscope, OM isolation, and adsorption isotherms. These analyses were carried out on lacustrine shale samples from the Lower Cretaceous Shahezi Formation, which is located in the Changling Fault Depression in Songliao Basin. The results show that the content of soluble OM (SOM) is low, accounting for 0.26%-3.75% of total OM. The contribution of pore development from SOM itself is limited. After extraction of SOM by chloroform, pore volume (PV), specific surface area (SSA), and average pore diameter (APD) exposed to gas molecules greatly increase. The existence of SOM has an obvious effect on pores of >10 nm, especially the clay mineral-related pores that contribute the most to the total PV. The content of kerogen is higher than SOM and accounts for 9.9%-65.5% (averaging 24.0%) of total PV in bulk shale, only second to minerals. More importantly, kerogen is the dominant contributor to organic PV, accounting for 95.8%-99.7% (averaging 98.3%) of the total organic PV. The pores developed in the kerogen peak at 0.4-0.7 nm and 10-30 nm. The solid bitumen (SB) followed by vitrinite and inertinite in kerogen contributes the most to the total kerogen PV.

Lessons of the Lost Shopping Complex of the Late 19th Century
Authors: SMOLENSKA Svitlana , BORYSENKO Artem
Published: April 2021

The paper is dedicated to the study and visual reconstruction of the Old Arcade – the first commercial structure of its kind for the Ukrainian city of Kharkiv, which was irrevocably lost during WWII. Its peculiar architecture reflected specifics of the place and way of citizens’ life. Its seven decades-long popularity and success as a commercial complex intrigue to this day. The methods of study consist of an analysis of texts (journal articles and books), visual documents (photographs and maps) depicting the central part of the city in 1870–1940s, as well as an on-site examination of other Kharkiv’s buildings from the end of 19th century. They also include a comparison with studies on the development of towns of adjacent regions, as conducted by other researchers. This allows authors of the paper to propose the first hypothetical spatial model of the Old Arcade, describing its supposed construction and stylistic solutions, as well as highlighting the stages of its transformation and the causes for its destruction during the war. The lessons of its spatial and visual integration with urban environment can be of use to designers and researchers of modern shopping complexes.
The Overview of Fracture Mechanics Models for Concrete
Authors: AKRAM Amanda
Published: April 2021

Fracture mechanics of concrete is a complex matter still thoroughly researched from different angles. It is not an easy task to describe fracture process in concrete, as there are many factors affecting crack development and propagation. Practical applications of fracture mechanics could allow engineers to design concrete structures more effectively and safely. At the minimum, it could help estimate the “safe” period of time left before the unstable, dangerous crack propagation. This utilitarian goal was the reason for many researchers to invent numerous theoretical models in order to describe the crack occurrence better. However, dealing with various analytical problems was not a simple matter and thus existing models of fracture mechanics for concrete have different limitations. Over the years first fracture theories for concrete were reviewed repeatedly. All of these investigations lead to modifications of older models in order to overcome found drawbacks, which proved not to be an easy task. Recently, new approaches to fracture analyses seemed to produce promising results, like universal size effect law (USEL) or modified two parameter fracture model (MTPM) with alternative ways for evaluating fracture parameters. In the paper some of them will be discussed together with other fracture models, starting from some of the very first ones introduced for concrete, like fictitious crack model (FCM) and crack band model (CBM).
