Authors: Ramya P. , Reddy T. Bhaskar
Published: May 2022

As the size of the biomedical databases areincreasing day-by-day, finding anessential featureset for classification problem is complex due to large data size and sparsity problems. Microarray feature ranking and classification is one of the major challenges to scientific and medical researchers due to its high dimensional feature space and limited number of samples. Feature transformation, feature ranking and data classification are the essential components to improve the microarray cancer prediction on high dimensional datasets. In this work, a novel framework is designed and implemented to classify the high dimensional data with high true positive rate. In the proposed work, a hybrid feature transformation, hybrid feature selection and advance classification approach are implemented to improve the true positive rate and error rate of the disease prediction. A novel principal component ranking measure is integratedin order to find the subset of features for classification problem. Finally, a hybrid decision tree classifier is used to predict the classification accuracy on the selected features set. Experimental results proved that the present framework has better performance compared to the traditional models for variable microarray datasets.

Published: May 2022

Deep Learning has indeed been widely used in many fields/areas of medicinal images classification, and a large number of publications have been published documenting its success. The key for achieving effective diagnosis and therapy is accurate characterization of medical pictures. However, because image interpretation is highly dependent on the subjective opinion of doctors, the results of image processing vary greatly amongst clinicians at different levels. Picture classification, target identification, and image analysis have all improved dramatically in recent years with environmental image data sets in domain of Image Processing. In this paper, we have presented a systematic survey on feature extracting and classifying the medical images using deep learning methods. Two new ideas are presented in this work. First and foremost, we classified presently trendy publications in a multi-level configuration. Second, this research article concentrates on supervised and poorly supervised learning techniques.

Homoeopathic cure is based on law of similar, and selection of remedy is based on Constitutional approach in management of any disease. Where the modern system of medicines makes the usage of external application like ointments, fungicides etc. In treatment of any skin infections like ring worm or tinea infections, which leads to suppression or palliation. So the disease tends to recur often and becomes a chronic disease. Removal of local symptoms of the local direction by external application leads to rousing up the internal disease and the other symptoms that previously existed in a latent state side by side with the local affection. So there is a wide scope for proper management and treatment of Tinea corporis in Homoeopathy. As in our system of medicine we do not treat the disease but we treat the individual who is suffering. Through individualization with constitutional remedy (Approach) we can treat both acute as well as the chronic phase of disease, to prevent further recurrence and complications of the disease. 9 articles were collected which are related to the efficacy of homoeopathic medicines in tinea infections.

Authors: Chandra Atanu , Ghosh Shrestha
Published: May 2022

Spontaneous pneumothorax (SP) is an uncommon complication of COVID-19, mostly in association with pre-existing lung conditions or under positive pressure ventilation. SP has been reported to occur in approximately 1% of the patients with COVID-19. We report here a case of a 47-year-old non-smoker gentleman without any pre-existing lung disease, who was admitted to our facility with fever, cough and shortness of breath and for 3 days with progressive worsening and chest pain over last 24 hours. Chest radiography revealed the diagnosis of right-sided pneumothorax with widespread patchy infiltrates on the left lung field. He was tested positive for COVID-19 and cultures for secondary bacterial infections were negative. A chest drain was secured and he was given antibiotics, steroid, heparin and remdesivir. However, the patient died within next 2 days due to progressive respiratory failure. This report emphasizes awareness of the possibility of SP as a complication of COVID-19; early identification and treatment of this entity may help decrease the associated mortality and morbidity. In conclusion, the possibility of SP should always be considered in the workup of a patient of SARS-CoV-2 infection having acute shortness of breath with or without chest pain. We would like to highlight this significant, though rare, presentation of COVID-19 and urge clinicians to maintain a high index of suspicion.

Published: May 2022

Os distúrbios oculares traumáticos em aves de rapina são consideradas emergências oftalmológicas que podem comprometer a visão e causar cegueira. A intervenção precoce do médico veterinário é essencial para o bom prognóstico do quadro clínico. O principal desafio é o manejo das aves com mínimo estresse e evitar a mortalidade. O objetivo do trabalho é relatar um caso perfuração ocular traumática em coruja-buraqueira (Athene cunicularia) e o tratamento cirúrgico por meio do uso de ceratoplastia com enxerto heterólogo corneano. O animal foi resgatado pela guarda florestal no município de Jundiaí-SP e levada para atendimento médico-veterinário após trauma ocular por linha com cerol. O exame clínico revelou várias escoriações nas asas e ferimento no olho direito. Inicialmente, optou-se pela terapêutica com colírio antimicrobiano à base de tobramicina por cinco dias, porém sem sucesso. Após nova avaliação clínica, decidiu-se pela técnica cirúrgica de ceratoplasia penetrante com a utilização de enxerto heterólogo corneano criopreservado da espécie canina. A técnica anestésica utilizada foi a prémedicação com a associação de cetamina, midazolam e tramadol pela via intramuscular, e a indução e manutenção anestésica com isoflurano em circuito aberto com gás diluente oxigênio. A medicação pós-operatória foi o uso de colírios à base de moxifloxacino, seis vezes ao dia, e à base de ácido etilenodiaminotetracético (EDTA), quatro vezes ao dia durante o período de hospitalização. A recuperação cirúrgica foi satisfatória, sem rejeição do tecido transplantado. Logo, o resultado visual das lesões perfurantes de córnea depende do diagnóstico precoce, a gravidade da lesão e da conduta terapêutica correta. O tratamento para as perfurações corneanas é cirúrgico, com enfoque na restauração da estrutura anatômica e função do bulbo ocular, bem como a reintrodução plena das aves aos seu habitat natural. A ceratoplastia com enxerto heterólogo de córnea é uma opção terapêutica para as lesões corneanas perfurantes de origem traumática. PALAVRAS-CHAVE: aves de rapina, ceratoplastia, oftalmologia, trauma ocular

Authors: BHARGAVA BN , RAO DRK
Published: May 2022

A spectral study has been made of gemomagnetic noise observed in the horizontal force of the geomagnetic field during the main phase of great storms of 12 and 13 November 1960 at the equatorial station of Trivandrum. The power spectra indicate that geomagnetic fluctuations are confined to frequency range of approximately 0.0004 to 0.008 cycles per second and that the periodicities in minute-range, obtained from selected periods of two storms, are almost same. The frequency range in which the noise is observed is in agreement with the range proposed by Cole (1966) in his theory for the energization of the ring current responsible for the main phase of n storm.

Divergence, vorticity and vertical motion in the fields of winter and monsoon circulations over India
Authors: SAJNANI PP
Published: May 2022

Using upper wind data of 69 pilot balloon and rawin stations in India, Pakistan, Burma and Ceylon, multi-level fields of divergence, vorticity and vertical motion have been computed on five consecutive days in the months of January and July 1958 to study the winter and monsoon circulations over the Indian region. Computations have been made at 37 grid points 2.5 degrees apart, with the help of a digital computer. A filtering technique was used to smoothen the observed winds so as to filter out noise.

 

The study provides a convenient method of computing divergence directly from observed winds instead of doing so indirectly thi:'i5ugh the vorticity equation.. The computed values of divergence and vorticity show that the two are of comparable magnitude. Examination of the divergence fields does not reveal narrow bands of convergence. characteristic of well defined frontal systems. The distribution of vertical velocities in the monsoon field indicates the existence of a source region over the eastern half of India and a sink over the western half.

Authors: BANERJEE AK , SHARMA KK , CHOWDHURY AB
Published: May 2022

In association with downdrafts from thunderclouds, an abrupt and abnormal rise in surface temperature of the order of 5 to 60C  was recorded at Nagpur and Visakhapatnam on two different days during summer season and with this abrupt rise, the surface temperature touched once again the day’s maximum temperature at these two places recorded earlier in the afternoon. These two cases are described in this paper and a plausible explanation for the abrupt rise in temperature is also presented.
A Pilot study for the estimation of probable maximum precipitation using Hershfield Technique
Authors: DHAR ON , KAMTE PP
Published: May 2022

Statistical technique developed by Hershfield has been used in this note to determine one-day PMP estimates for the plain areas of Uttar Pradesh. Extreme annual one-day rainfall data was collected for 230 stations in this region from the scrutiny of daily rainfall data of 60 to 70 years from 1891 to 1960. The enveloping value for the frequency factor Km in the modified Chow's general formula was found to be 12 for this region. This value was utilized in obtaining PMP values for 230 stations in this region. On the basis of this data a generalized chart of PMP was prepared for the plain areas of Uttar Pradesh for one-day duration. It has been seen that on an average in this region one-day PMP values obtained by this technique are 2.4 times the highest observed one-day rainfall during the past 60 to 70 years.

Authors: DUBE RK
Published: May 2022

The structure of the Upper Mantle has been studied from the P-wave travel times, using the computation of Dowling and Nuttli. Results indicate the presence of a low velocity layer 140 km below the M-discontinuity and its thickness is estimated as about 50 km. A steep velocity gradient below the low velocity layer explains the observed results.
The Cumulative Frequency Distribution of Rainfall of Different intensities
Authors: KULKARNI NS , PANT MB
Published: May 2022

The cumulative frequency distribution of rainfall of different intensities during southwest monsoon is studied for twenty stations in India, The distribution is found to be exponential in all the cases.

 

The equation y = ae-bX (where y is the cumulative frequency of daily rainfall exceeding an amount X and a, b are constants) is very satisfactorily found to fit the data, The curve has been fitted to the observed data by the method of least squares, It has also been shown that the constants a and b can be found from the number of rainy days and the total seasonal rainfall.

 

The variations of the parameters a and b with rainfall and number of rainy days are discussed.
Spells of heavy rainfall in association with western disturbances over Northwest India during the monsoon of 1966 -A quantitative approach
Authors: KUMAR SURENDRA , SAXENA RKS
Published: May 2022

Three spells of heavy rainfall which occurred over northwest Uttar Pradesh, Himachal Pradesh and the Punjab in association with western disturbances moving across extreme northwest India during the monsoon of 1966 were studied.

 

It has been shown quantitatively that the increase in convergence at 900 m a. s. l. occurred over northwest India with approaching western disturbances and areas of very heavy rainfall had marked convergence at 900 m level, superimposed by marked divergence at 9.0km a.s.l.
Surface wave dispersion and crustal structure in Asia-Indo-Pakistan sub-continent
Authors: NAG SK
Published: May 2022

Long period vertical seismograph records of Shillong for six earthquakes having epicentres at southern Iran have been studied. The dispersion of surface waves- of Rayleigh type were computed. Inference regarding the average structure of the crust across the Indo-Pakistan sub-continent was made by comparison with theoretical curves corresponding to Dorman case 8007. It was concluded that the average thickness of the crust in this region is about 45 km. Surface waves due to one earth quake having epicentre in Indo-Burma border have also been studied from the record of Long period vertical seismograph of Dehli.

Is it possible to increase rainfall in the semi-arid regions of Rajasthan by reducing quantity of dust suspended in the atmosphere ? -No
Authors: DESAI BN
Published: May 2022

The nature of air masses during the monsoon season and the causes responsible for (1) small rainfall and (2) desert conditions over west Rajasthan have been discussed. It is shown that reduction in the quantity of dust suspended in the atmosphere can increase neither the depth of the moist layer nor the rainfall over the area as suggested by Brysonand co-workers (1964. 1967-); stable conditions between about 1. O and 2. O km are not considered as being due to subsidence which can ordinarily occur over the area only above about 3' O km.
Observations of Turbulence at Delhi during the winter months - November 1966 to February 1967 with the F-type Radiosondes
Authors: VENKITESHWARAN SP , SARAISINHA HARSURENDRA , MAZUMDAR S
Published: May 2022

Study of turbulence at Delhi during the winter months when the westerly jets prevail was made by special F-type radiosonde ascents from November 1966 to February 1967 and in April 1967" The vertical components of gusts and their thicknesses were determined by measuring the rate of rotation of the fan from the length of complete Olland cycles which consists of 1000 impulses" Since the duration of the gust may not last as much as a full cycle, lengths of tapes for 100 impulses and 500 impulses were measured. It was then found that the duration of the gnats is only of the order of 200-300 impulses. The vertical components of the gusts were therefore larger and thicknesses smaller when the length of 100 impulses were used. One of the interesting features at Delhi was the presence of turbulence fu thin layers of air (about 1500 m thick), fu which the lapse rate was different from those in the layers above and below. These regions were above the jet stream and were between 150 and 100-mb levels.
Survivorship of Anatomic Total Shoulder Arthroplasty
Authors: Piper Christine , Neviaser Andrew
Published: May 2022

Anatomic total shoulder arthroplasty provides pain relief and improved quality of life for patients suffering from glenohumeral arthritis. The 10-year survival rate for these implants has been most recently reported at 96%. As the number of shoulder arthroplasties per year increases, it is important to evaluate factors associated with failure. Patient-specific variables such as age, sex, medical comorbidities, a history of previous shoulder surgery, and rotator cuff integrity can influence implant survival. Both surgeon and hospital volume have been shown to affect perioperative outcomes. Implant design and glenoid pathoanatomy are important structural considerations because both have a causal relationship with survivorship. Modifiable factors, such as smoking, body mass index, and alcohol or opioid consumption, should be addressed preoperatively when possible. Modifiable factors that pertain to surgery are equally as important; it is the responsibility of the surgeon to be aware of the reported outcomes for varying implants and technique-related pearls and pitfalls. For those perioperative factors that are nonmodifiable, it is prudent to counsel patients accordingly because these individuals may be more likely to require an eventual revision procedure.
Symptoms to surgery: factors associated with delays to carotid endarterectomy for symptomatic stenosis in an Irish tertiary vascular centre
Authors: Foley MP
Published: May 2022

Introduction: Carotid endarterectomy (CEA) is the accepted treatment for stroke risk reduction in patients with symptomatic 50–99% carotid artery stenosis. Best practice guidelines recommend surgery be performed within 14 days of index symptoms to achieve maximum benefit; however, achieving this target can be difficult. Late presentation and presentation to hospitals without onsite vascular capabilities are two recurring reasons for delayed CEA across the literature. Methods: All symptomatic CEAs performed between January 2017 and December 2019 were retrospectively extracted from an electronic institutional database and analysed to determine the proportion of CEAs meeting benchmark targets and to assess factors contributing to delays. Results: A total of 124 CEAs were performed for 62 strokes and 62 transient ischaemic attacks (TIAs); 71.8% (n=89) were male and the median (range) age was 71.0 years (43–88). The median delay between initial symptom and CEA was 14 days (range 1–183). Sixty-six patients (55%) had surgery within 14 days of the index symptom. Patients presenting with ‘Face Arms Speech Time’ (FAST) symptoms were significantly more likely to undergo timely CEA, largely due to earlier presentation to hospital (p=0.021, OR 2.563, 95% CI 1.143 to 5.747). Presentation directly to a tertiary vascular centre was significantly associated with CEA within 14 days compared with referrals from external hospitals (p=0.002), with a median symptom-to-surgery interval of 12.0 days and 25.0 days, respectively (p=0.001) Conclusions: Our results are comparable to UK and Australian national audits, although a significant number of CEAs fell outside the 14-day target. Protected pathways between referring hospitals and vascular centres are needed to ensure all patients have equal access to urgent CEA. Designating CEA within 14 days as a key performance indicator for stroke management will hopefully incentivise hospitals to expedite this high-risk cohort. Furthermore, re-auditing with an emphasis on patients turned down for intervention due to recurrent events while awaiting CEA may further highlight the need to prioritise symptomatic carotids.
