Authors: Rashidi Homiera , Ghaderian Bahman , Sedaghat Alireza , Latifi Mahmoud , Naimi Zohre
Published: February 2022

Anti-thyroid treatment and radioiodine are mainly used treatments for patients with thyrotoxicosis. The effect of anti-thyroid drugs (ATDs) on radioactive iodine's therapeutic effectiveness in hyperthyroidism remains controversial. This study aimed to determine the treatment effectiveness and complications in patients with thyrotoxicosis receiving radioiodine treatment with or without adjunctive anti-thyroid drugs in a tertiary endocrinology center in Ahvaz, Iran. A total of 165 patients with thyrotoxicosis (50 males and 115 females) were recruited in this retrospective clinical study. These patients were divided into two groups: one group underwent natural iodine therapy without being treated with anti-thyroid drugs (N= 86), and the other group was first treated with anti-thyroid drugs and then treated with iodine (N= 79). Then, the frequency of euthyroidism, thyroid storm, thyroiditis, hypothyroidism and the time to reach euthyroidism is evaluated. The results showed no difference between the two groups when reaching the euthyroid and the mean numerical mean TSH at the time of hypothyroidism. However, the average dose of iodine received in the concomitant drug group was lower. No thyroid storm was observed in the two groups regarding complications after treatment. Also, the prevalence of hypothyroidism and thyroiditis were not significantly different between the two groups. Iodine therapy with and without the use of anti-thyroid drugs (ATD) in low-risk patients with thyrotoxicosis has no difference in treatment outcomes, response to treatment, and subsequent complications.

Authors: Lui Gough Yumu , Loughnane Dervla Catherine , Polley Caitlin Amanda , Jayarathna Titus Nanda Kumara , Breen Paul Peter
Published: February 2022

BACKGROUND

An anticipated surge in mental health service demand related to COVID-19 has motivated the use of novel methods-of-care to meet demand given workforce limitations. Digital health technologies in the form of self-tracking technology have been identified as a potential avenue, provided sufficient evidence exists to support its effectiveness in mental health contexts.

OBJECTIVE

The objective of this literature review is to identify physiological monitoring capabilities of the Apple Watch relevant to mental health monitoring, to examine the accuracy and validation status of these measures, and the implications of these measurements on mental health treatment.

METHODS

A literature review was conducted in June-July 2021 for both published and grey literature pertaining to Apple Watch, mental health and physiology. The literature review identified studies validating sensor capabilities of the Apple Watch.

RESULTS

A total of 5,583 paper titles were identified, with 115 papers reviewed in full. Of these, 19 papers were related to Apple Watch validation or comparison studies. Most studies showed the Apple Watch to measure heart rate acceptably with increased errors in case of movement. Accurate energy expenditure measurements are difficult for most wearables, with Apple Watch generally providing best results compared to peers, despite overestimation. Heart Rate Variability measurements were found to have gaps in data, but was able to detect mild mental stress. Activity monitoring with step counting shows good agreement, although wheelchair use was found to be prone to overestimation and poor performance on overground tasks. Atrial Fibrillation detection showed mixed results in part due to a high inconclusive result rate but may be useful for ongoing monitoring. No studies recorded validation of the Sleep app feature, however, accelerometer-based sleep monitoring showed high accuracy and sensitivity in detecting sleep.

CONCLUSIONS

The results are encouraging regarding the application of Apple Watch in mental health, particularly as heart rate variability is a key indicator of changes in both physical and emotional states. Particular benefit may be derived through avoidance of recall bias and collection of supporting ecological context data. However, a lack of methodologically robust and replicated evidence of user benefit, supportive health economic analysis and concerns around personal health information remain key factors that must be addressed to enable broader uptake.
Efficacy of Telemedicine Utilization for Cardiac outpatients’ care during the pandemic of COVID 19, A large center experience in the wave of the pandemic. (Preprint)
Authors: Alhejily Wesam
Published: February 2022

BACKGROUND

Synchronous telemedicine using teleconferencing may play a role in clinical care. In a tertiary care center, video conferencing enhanced virtual clinics were established via a new application platform. They were introduced during COVID19 pandemic to connect patients to trained health care providers via a secured line. While maintaining patients’ privacy, they were theorized to offer effective communications and continuous clinical care.

OBJECTIVE

In this cross-sectional cohort study, we ought to examine the impact of service and the assistance they may offer to cardiac patients in the outpatient setup.

METHODS

A prospective cohort study looking at all video-conferencing virtual clinics’ visits during the pandemic with primary focus on cardiac out-patient clinic, addressing primary endpoints of need for admission or emergency visits from cardiac demises during the pandemics and secondary endpoint of patient satisfaction based on patients’ experiences.

RESULTS

A total of 6000 live care video-based chats were made over 10 months period from March 10th, 2020, to January 30th, 2021, among which 277 patients were evaluated in the virtual cardiac clinic, of these 193 (69.7%) were males, with mean age of 48±15. 60 (22.3%) patients were requested to present to clinic for further evaluation and testing, 20 (7.2%) patients were asked to visit the emergency room of whom 8 (2.8%) patients were hospitalized. All 8 were admitted for high-risk findings that require immediate medical attention, 4/8 underwent cardiac catheterization, mean duration of admission was 2±1 days. When compared to regular walk-in care, there was a statistical difference in admission rate and emergency visits (p=0.001) and (p=0.0001) respectively, both were statistically higher in the virtual clinic. The satisfaction rate in 5- scale-grading system, was 97% of 4 and above recommending the continuation of the service beyond pandemic time.

CONCLUSIONS

Video-enhanced virtual cardiology clinic works safely and efficiently during COVID-19 pandemic with a difference in admission rate and ER visits when compared to walk in clinic. It can be used during non-pandemic time to reduce load on hospital and clinic crowdedness. It also decreases the chances of COVID19 transmission indirectly by re-enforcing physical distance.

Explaining Double Split Experiment with Geometrical Algebra Formalism
Authors: Soiguine Alexander
Published: February 2022

The Geometric Algebra formalism opens the door to developing a theory upgrading conventional quantum mechanics. Generalizations, stemming from implementation of complex numbers as geometrically feasible objects in three dimensions; unambiguous definition of states, observables, measurements bring into reality clear explanations of conventional weird quantum mechanical features, particularly the results of double split experiments where particles create diffraction patterns inherent to wave diffraction. This weirdness of the double split experiment is milestone of all further difficulties in interpretation of quantum mechanics.
The Ten Relationships of Globalization
Authors: Zou Lixing
Published: February 2022

This paper study the complex relationships faced by globalization. First, the relationship between commonality and diversity are objectively inevitable. Second, artificial intelligence and human development need to avoid harm in the direction of healthy human development. Third, the virtual space and the real world should never be “flipped by things” not should the things be “made void”. Fourth, digitalism and humanism: digitalism is becoming a cult, traditional humanism is being eclipsed, but human math cannot trump Heaven’s law. Fifth, humanity and nature need to be integrated. Sixth, the past and the future represent forms of life. Seventh, the East and the West is one result, though there might be a hundred anxious schemes. Eighth, emergency and normality:uncertainty is eternal, normality is relative, human safety and security need normalized emergency mechanism. Ninth, assets and liabilities:everything has the attributes of both assets and liabilities, needs to follow the principle of systemic balance. Tenth, the relationship between the nation-state and globalization are a pair of balanced wheels, which directly reflect the civilization and barbarism of human society. All kinds of relations and contradictions in the world today are created by inbalance and need to be dealt with by balance.

The existence of honorary staff who cannot be appointed as permanent employees is one of the problems that have yet to be resolved. The honorary employees certainly want to get their rights as employees who work to devote themselves to the community. Employees who feel that job security is certainly less able to accept changes in the conditions of the work environment which would make them unable to develop in the work environment. Jobs that are not permanent will create job insecurity conditions. The attitude of employees in facing a change is, of course, different, employees with high resilience can be interpreted as being able to adapt and can change a chaotic environmental condition to solve problems and turn them towards a positive one. The purpose of this study is to see how much influence the resilience of job insecurity has on honorary employees. This research is quantitative research with the number of subjects 129 honorary employees. The method of data collection uses the Job Insecurity Quisionare scale and the CD-RISC scale. Data analysis using a linear regression test. The results showed that ß -0.252 p0,000 note that there was a negative effect on resilience towards job insecurity, which means that the higher the resilience, the lower the job insecurity. Resilience contributed significantly (9.3%) to job insecurity.
Typology of pragmatic implications from the point of view of interaction between pragmatics and semantics
Authors: Kiklewicz Aleksander
Published: February 2022

The subject matter of the study is communicative implications as one of the forms of implementation of speech acts. The starting point is the well-known theory of H. P. Grice, in which pragmatic implications are based on the principle of cooperation. The author shows the limitations of Grices theory, which presents the communicative conditions of implications, but does not present the communicative consequences. As an alternative, the author proposes the concept of pragmatic implications, taking into account the premises and consequences of indirect speech acts. Considering implication as a two-place relation between antecedent and consequent, the author identifies three types of implications that differ in the type of information in the antecedent and consequent parts: 1) semantic antecedent pragmatic consequent; 2) pragmatic antecedent pragmatic consequent; 3) pragmatic antecedent semantic consequent. This approach makes it possible to present indirect communication to the fullest extent, and also to explain many communicative phenomena in terms of the interaction between semantics and pragmatics. Implications are interpreted as the result of mental processing of conditionally categorical syllogisms, in which the first premise is an element of the cultural worldview. Thus, the author shows the relative nature of the opposition of conventional and communicative implications. The article uses the material of the modern Russian language, borrowed from various sources: journalism, fiction, the Internet, urban folklore and colloquial speech. The leading research method was pragmatic, namely, illocutionary, analysis with elements of discourse content analysis.

Penerapan protokol kesehatan terhadap pandemi Corona Virus Disease 2019   (Covid-19) di tempat umum dapat dilakukan dengan tes identifikasi bau berdasarkan penilaian fungsi indera penciuman. Penelitian ini bertujuan untuk merancang prototipe alat uji indera penciuman yang bekerja secara otomatis sebagai wahana protokol kesehatan Covid-19 dan mengetahui pengaruh kontrol fuzzy Mamdani terhadap kinerja perangkat dalam mengelola pengujian aroma. Prototipe dirancang di Badan Pengkajian dan Penerapan Teknologi (BPPT) menggunakan uji identifikasi bau dengan memberikan pengujian 5 jenis aroma secara acak yang dihasilkan oleh odor generator penghasil aroma. Generator aroma dilengkapi dengan kendali fuzzy Mamdani sebagai pengontrol PWM kecepatan kipas yang digunakan dalam menghembuskan gas aroma, dengan parameter masukan himpunan fuzzy sensor jarak dan sensor pendeteksi gas Volatile Organic Compounds (VOC). Pengujian tersebut didasarkan pada skor tes penciuman dari identifikasi setiap responden dengan total skor maksimal 5 pada identifikasi aroma yang sempurna. Hasil uji indra penciuman untuk setiap responden dikirim ke server yang terintegrasi dengan platform IoT ThingsBoard dan dikirim kepada setiap responden yang melakukan pengujian. Berdasarkan hasil pengujian fungsi prototipe, nilai keluaran PWM hasil perhitungan fuzzy Mamdani mikrokontroler Arduino memiliki akurasi sebesar 99,70% berdasarkan perbandingan simulasi di Matlab. Kendali fuzzy Mamdani dapat meningkatkan persentase rata-rata skor jawaban benar pada tes indra penciuman sebesar 14% terhadap 3 responden dan hasil tes dapat dikirim ke email akun ThingsBoard untuk setiap pengguna yang terdaftar pada sistem.

Tangan adalah salah satu bagian tubuh manusia yang sering digunakan. Aktivitas berlebihan bisa menjadikan otot pada tubuh manusia mengalami kelelahan sehingga mengakibatkan nyeri. Penyembuhan nyeri otot bisa dilakukan menggunakan salah satu alat medis yaitu therapy infrared. Terapi infrared adalah penyinaran lampu pijar inframerah ke bagian tubuh yang menembus bagian kulit sehingga dapat melancarkan peredaran darah. Penggunaan metode VAS sebagai nilai indikator tingkat nyeri. Metode ini dilakukan dengan uji coba ke pasien di RSUD Jombang. Penelitian ini dilakukan dengan 3 percobaan yaitu pasien diminta untuk melakukan handgrip 10, 20 dan 30 kali, dan masing-masing akan diukur tegangan sensor ototnya baik sesudah disinari infrared maupun sebelum disinari, sehingga dihasilkan data sebagai berikut : jika memakai 10 handgrip terjadi penurunan tegangan otot dari 250,784 mV menjadi 240,833 mV, jika pasien memakai 20 handgrip dihasilkan penurunan tegangan otot dari 255,375 mV menjadi 246,94 mV dan percobaan memakai 30 handgrip dihasilkan penurunan tegangan dari 278,026 mV menjadi 264,566 mV, sehingga terdapat hasil yang signifikan antara sebelum dan sesudah penyinaran inframerah

Migration and remittances in Kosovo are promoters of local economic development and have an important role in the economic well-being of citizens, as well as other aspects in financing and developing the economy through stimulation. This article will evaluate and assess using subjective research methodologies the impact of diaspora during the pandemic period time. Anytime was crucial for many citizens that depend on the remittances, according to this statement, we mention that diaspora has a major role also in economic development in general. So, the purpose of this paper is to define and deeply explain the socio-economic outcomes of diaspora during the pandemic of COVID-19. In this way, we have used two types of data, primary and secondary for further analysis where we have used different techniques such as descriptive, crosstab, and Chi-square, which we have analyzed and shown by using SPSS software. Also, our paper is based on Hamdi Hoti and Hoxha’s (2018) and Jusufi and Ukaj’s (2020) findings and suggests that remittances have always been one of the most important and stable sources of external financing for the country. This is very important for states such as the Republic of Kosovo.
Deriving Stress Limits for Fatigue Design with a Consideration of the Manufacturing Process Influence
Authors: Hell Matthias , Wagener Rainer
Published: February 2022

The material behaviour of forged components is subjected to an intensive
influence of the manufacturing process. The local logarithmic strain as
well as the cooling conditions may influence the cyclic stress-strain
behaviour as well as the fatigue behaviour of the material. For a
reliable lightweight design of components, those effects have to be
considered already during early product development stages, because the
definition of the component geometry will already imply process related
limitations regarding the achievable local material propeties. A
combination between a process simulation and a strain-based fatigue life
estimation, including a customized testing strategy, allows a
consideration of the manufacturing process influence as well as an
implementation of statistical and mechanical size effects and improves
the quality of the fatigue assessment and the reliability of numerically
derived stress limits for component design compared to the state of the
art.

ABSTRACT Objective: The aim of this study was to investigate key
antecedents of moderate and severe neonatal hypoxic ischemic
encephalopathy (HIE) in a large contemporary Australian birth cohort.
Design: A retrospective cohort study of all births meeting the inclusion
criteria between 2016-2020. Setting: The Mater Mothers’ Hospital,
Brisbane, Australia. This is a quarternary perinatal center and
Australia’s largest maternity hospital. Population: All non-anomalous,
singleton liveborn infants, >35+0 weeks gestation. Methods:
Univariate and multivariate firth logistic regression were used to
account for imbalanced frequency classes. Main outcome measure: Neonatal
moderate and severe HIE. Results: Overall, 133/46041 (0.29%) infants
were diagnosed with HIE, and 56 (0.12%) were diagnosed with
moderate/severe HIE. Nulliparity, type 1 diabetes mellitus and maternal
intensive care unit admission were associated with increased odds of
moderate/severe HIE. Intrapartum risk factors included emergency
cesarean birth, emergency cesarean for non-reassuring fetal status or
failure to process, intrapartum hemorrhage, and an intrapartum sentinel
event (shoulder dystocia, cord prolapse, uterine rupture, placental
abruption). Neonatal risk factors included male sex, birth at late
preterm gestation (35+0 – 36+6 weeks), Apgar score <4 at 5
minutes, severe respiratory distress requiring ventilatory support and
severe acidosis at birth. Conclusions: This cohort study identified a
series of potentially modifiable maternal and obstetric risk factors for
HIE. Risk factors for HIE do not appear to have changed significantly
despite recent advances in obstetric care. Key words: pregnancy, fetus,
fetal distress, intrapartum hypoxia, hypoxic ischemic encephalopathy,
cerebral palsy Funding source: The authors acknowledge research support

From the Hindu Vedas and the ancient Greek philosophy to the modern transdisciplinary vision and complex thought are solid proofs that the identification of the truly indivisible, ultimate particle. Science has reached nowadays the frontiers of metaphysics, and quantum physics, the levels of reality, the fractals, the holographic universe, the standard model of cosmology, etc. cause human beings to ask themselves again the questions that science cannot answer: Where do we come from? Who are we? Where are we going?
