Published: November 2019

Un tic es un movimiento (tics motores) o sonido (tics vocal o fónico) breve, repentino y no rítmico. El DSM 5 define tres trastornos por tics: transitorios, vocales o motores persistentes y, el trastorno de la Tourette. Su diagnóstico es eminentemente clínico, siendo cruciales la historia clínica y la observación para realizar un adecuado diagnóstico diferencial con otros trastornos hipercinéticos del movimiento, tales como distonías, corea o atetosis, entre otros. Se presenta el caso de un niño de nueve años diagnosticado luego de dos meses de síntomas y de tratamientos inadecuados, quien mejoró luego de establecerse un diagnóstico correcto y ofrecerse terapia farmacológica dirigida.

Published: November 2019

Campylobacter sp. es una bacteria que se adapta a diferentes condiciones y permite un cambio en su forma y requerimientos metabólicos, dificultando su diagnóstico microbiológico. Presentamos el caso de un paciente oncológico de 65 años con bacteriemia por Campylobacter sp. Se desarrolló el cultivo de microbiología clásico en microaerofilia a 42 oC, cultivo aeróbico en agar sangre a 37 oCy hemocultivo aeróbico a 37 oC. Además, se realizó la reacción en cadena de la polimerasa para identificar el agente. La bacteria creció en todos los medios mostrando su termotolerancia y tolerancia a diferentes concentraciones de oxígeno, además de presentar una forma en espiral en el hemocultivo aeróbico. Finalmente, enfatizamos la flexibilidad fisiológica de la bacteria para adaptarse a diferentes condiciones y la importancia de la prueba molecular para identificar al agente, en especial en el crecimiento aeróbico en forma de espiral que pudiera confundirse con otras espiroquetas que causan episodios febriles.

Published: November 2019

With regard to the water shortage in several regions of South East Asia, the paper focuses on the development of a sustainable Industrial WasteWater Management Concept with the focus on Reuse (brand name: IW2MC → R) to reduce water consumption from natural resources. The IW2MC → R includes the sustainable treatment of wastewater in industrial parks (IP) to provide reuse water for different purposes. The main objective is to reach the highest possible Industrial Park Reuse Factor (IPRF). The IPRF describes the relation between wastewater inflow to the central wastewater treatment plant and the outflow of reuse water for different applications. The Infrastructure Reuse Factor (IRF), one component of the IPRF, relates to infrastructural reuse applications (e.g. irrigation, street cleaning, toilet flushing). To determine the IRF, a model industrial park is applied. A first calculation resulting in an IRF of ∼25% includes reuse applications for irrigating green spaces, street cleaning, and toilet flushing. In cases when other applications for reuse water are considered (e.g. cooling or firefighting water), the IRF can be higher than 25%. Thus, the IW2MC → R provides a sustainable solution strategy, especially for water-stressed regions, to drive new IP developments by reducing water extraction from natural resources.

Published: November 2019

Objective:

In this work, the loading of nicotine onto mesoporous silicate materials and its
release into a phosphate buffer solution at 37°C were investigated.

Methods:

The mesoporous silicate materials designated as MCM-41 were prepared with different pore
sizes via using alkyltrimethylammonium bromide surfactants with different alkyl chain lengths of carbon
atoms 12, 14, and 16. The mesoporous silicate systems were characterized by X-Ray Diffraction
(XRD), Scanning Electron Microscopy (SEM), N2-adsorption–desorption isotherms, and FT-IR spectroscopy.

Results:

Loading of nicotine was confirmed by FTIR and thermal gravimetric analysis and was determined
by High-Performance Liquid Chromatography (HPLC).

Conclusion:

A slight increase in loading capacity with increasing pore size was observed, with a loading
capacity of about 17% for MCM-41(16). The release of nicotine was monitored by HPLC and was
almost complete for MCM-41(14) and MCM-41(16) in 8 h.
Traumatic Brain Injury: A Forensic Approach: A Literature Review
Authors: Bertozzi Giuseppe , Maglietta Francesca , Sessa Francesco , Scoto Edmondo , Cipolloni Luigi , Di Mizio Giulio , Salerno Monica , Pomara Cristoforo
Published: November 2019

:

Traumatic brain injury (TBI) is the principal cause of invalidity and death in the population under 45 years of age worldwide.

:

This mini-review aims to systematize the forensic approach in neuropathological studies, highlighting the proper elements to be noted during external, radiological, autoptical, and histological examinations with particular attention paid to immunohistochemistry and molecular biology.

:

In the light of the results of this mini-review, an accurate forensic approach can be considered mandatory in the examination of suspected TBI with medico-legal importance, in order to gather all the possible evidence to corroborate the diagnosis of a lesion that may have caused, or contributed to, death. From this point of view, only the use of an evidence-based protocol can reach a suitable diagnosis, especially in those cases in which there are other neuropathological conditions (ischemia, neurodegeneration, neuro-inflammation, dementia) that may have played a role in death.

:

This is even more relevant when corpses, in an advanced state of decomposition, are studied, where the radiological, macroscopic and histological analyses fail to give meaningful answers. In these cases, immune-histochemical and molecular biology diagnostics are of fundamental importance and a forensic neuropathologist has to know them. Particularly, MiRNAs are promising biomarkers for TBI both for brain damage identification and for medico-legal aspects, even if further investigations are required to validate the first experimental studies. In the same way, the genetic substrate should be examined during any forensic examination, considering its importance in the outcome of TBI.
The Role of PGC-1α in Digestive System Malignant Tumours
Authors: Zhang Qiushuang , Chen Wei , Xie Chao , Dai Xiaoshuo , Ma Junfen , Lu Jing
Published: November 2019

Background:

Cancer is increasingly becoming the leading cause of death in many countries,
and malignant tumours of the digestive system account for majority of cancer incidence and mortality cases.
Metabolism has been identified as a core hallmark of cancer. Peroxisome proliferator activated receptor gamma
coactivator-1 alpha (PGC-1α) is a pivotal regulator of mitochondrial energy metabolism. Accumulating evidence
reveals that PGC-1α is essential in cancer development.

Objective:

We summarize the latest research progress of PGC-1α in common digestive system malignant tumours.
Some related modulators and pathways are analyzed as well.

Methods:

We conducted a literature review on the development of PGC-1α in common digestive system malignant
tumours.

Results:

In colorectal cancer, PGC-1α appears to provide growth advantages by different pathways, although it
has also been reported to have opposite effects. The previous studies of PGC-1α on liver cancer also demonstrated
different effects by sundry pathways. Concerning gastric cancer, PGC-1α promotes cell proliferation,
apoptosis in vitro and tumour growth in vivo. AMPK/SIRT1/PGC-1α is related to the inhibition of apoptosis in
pancreatic cancer cells. Pancreatic cancer stem cells are strongly dependent on mitochondrial oxidative phosphorylation.
PGC-1α is required to maintain the stemness property of pancreatic cancer stem cells.

Conclusion:

We explore diverse mechanisms that explain the dichotomous functions of PGC-1α on tumorigenesis,
and discuss the latest research concerning digestive system malignant tumours. This review would provide
better comprehension of the field and a basis for further studies associated with PGC-1α in digestive system
cancers.

Authors: Pasandideh Roya , Hosseini Seyed M. , Veghari Gholamreza , Hezarkhani Sharebeh
Published: November 2019

Background:

Insulin resistance (IR) is an independent cardiovascular risk factor. IR predisposes
to metabolic syndrome and diabetes. Meanwhile, little evidence exists about the effect of
levothyroxine replacement treatment (LRT) on IR in hypothyroid patients.

Objective:

To investigate metabolic and anthropometric indices of IR in hypothyroid patients before
and after 8 weeks of LRT.

Methods:

This pre-post study evaluated the 8 weeks outcomes of LRT on 66 patients with recently
diagnosed hypothyroidism. Outcome measures included body mass index (BMI), waist circumferences
(WC), waist to hip ratio (WHR), waist to height ratio (WHtR), body fat percent (BF%), free thyroxin
(FT4), triglyceride (TG), low density lipoprotein (LDL), fasting plasma levels of glucose (FPG) and
insulin. Sex- specific cut offs of two metabolic indices i.e. the triglyceride-glucose (TyG) and the homeostasis
model assessment (HOMA) were used for IR diagnosis. The changes in TyG and HOMA
were also compared after LRT.

Results:

Participants were overt and subclinical hypothyroidism 71% and 29%, respectively. After
LRT the mean values of the following anthropometric indices significantly decreased: weight (79.61
vs. 78.64), BMI (29.53 vs. 29.2), WC (98.25 vs. 97.39) and BF% (35.34 vs. 34.95). After LRT the
HOMA and TyG had no significant changes relative to their initial values. Also, IR that was determined
on the basis of these metabolic indices more commonly observed in participants.

Conclusion:

Despite decreasing some anthropometric indices, the diagnosis of IR based on metabolic
indices increased following 8 weeks LRT in hypothyroid cases.

An Interactive and Predictive Pre-diagnostic Model for Healthcare based on Data Provenance
Authors: Ahmed Zhwan Namiq , Hussien Jamal Ali
Published: November 2019

The future of healthcare may look completely different from the current clinic-center services.  Rapidly growing and developing technologies are expected to change clinics throughout the world. However, the healthcare delivered to impaired patients, such as elderly and disabled people, possibly still requires hands-on human expertise. The aim of this study is to propose a predictive model that pre-diagnose illnesses by analyzing symptoms that are interactively taken from patients via several hand gestures during a period of time. This is particularly helpful in assisting clinicians and doctors to gain better understanding and make more accurate decisions about future plans for their patients’ situations. The hand gestures are detected, the time of the gesture is recorded and then they are associated to their designated symptoms. This information is captured in the form of provenance graphs constructed based on the W3C PROV data model. The provenance graph is analyzed by extracting several network metrics and then supervised machine-learning algorithms are used to build a predictive model. The model is used to predict diseases from the symptoms with a maximum accuracy of 84.5%.

Published: November 2019

Pallikaranai Wetland, within Tamil Nadu, India, receives runoff from the surrounding urban area, including polycyclic aromatic hydrocarbons (PAHs). PAH have been listed as Priority Pollutants by US EPA (2014) due to their carcinogenic, genotoxic and teratogenic potential in humans and form DNA adducts. In addition to the run-off that the area receives, dumping and burning of waste occurs here and hence, this study was designed to evaluate PAH contamination in three fish species commonly found in the wetland considering the ongoing indiscriminate dumping of assorted waste here. Between January and April 2018, fifty fish comprising of seven subjects of Oreochromis aureus, thirty four subjects of Oreochromis mossambicus and nine subjects of Oreochromis niloticus were collected from Pallikaranai wetland. The fish were then necropsied and were analysed for fifteen PAH. Total PAH load was greatest in Oreochromis mossambicus. Naphthalene and phenanthrene were detected in all samples. While levels of sum of four carcinogenic (PAH4: Sum of Benzo (a) pyrene, Chrysene, Benzo (a) anthracene and Benzo (b) fluoranthene) in one subject of Oreochromismossambicus manifolds higher than the toxic levels as per the European Union guidelines, and was closely trailing the limits in one individual of Oreochromisaureus, the levels of the other 48 fish were below the limit of concern. Oreochrmoismossambicus is near threatened in its home range (Mozzambique) according to the IUCN and PAH may be contributing to the threats that the species faces. While the Oreochromis mossambicus is not threatened in India, it is imperative to assess the accumulation patterns of PAH in the species elsewhere to contribute data to the conservation in the home range.
