Efficacy of core stability versus task oriented trainings on balance in ataxic persons with multiple sclerosis. A single blinded randomized controlled trial

BACKGROUND

Balance and ataxic symptoms are commonly encountered in people with multiple sclerosis (PwMS). Many intervention approaches have been proposed to address balance in PwMS. The purpose of this study was to investigate the efficacy of adding core stability versus task oriented trainings on traditional approaches on balance in ataxic PwMS.

METHODS

Forty five ataxic relapsing-remitting PwMS from both sexes were randomly assigned into three identical groups. Control group (CG) treated with conventional balance exercise program; study groups I (GI) and II (GII) received respectively additional training using core stability exercises and task oriented trainings. Outcome measures recorded pre and post study period included stability index (SI), anterior posterior stability index (APSI), and mediolateral stability index (MLSI) using Biodex stability system in addition to the Berg balance scale (BBS).

RESULTS

Post treatment, the results indicated significant improvement in (SI) and (APSI) (p<0.05), and non-significant improvement (p>0.05) in (MLSI) and BBS in CG. In GI and GII there was a significant improvement in all balance measures (p<0.05). Comparison of post treatment results between groups indicated a significant improvement of GII compared to CG in all study measures, GI showed non- significant difference in all balance measures compared to the CG(P>0.05).

CONCLUSION

In PwMS balance rehabilitation should be multimodal; core stability exercises and task-oriented training in addition to conventional balance training are effective to improve balance and should be considered as an essential part of the training program for balance rehabilitation in ataxic PwMS. Task-oriented training in addition to conventional balance rehabilitation seem to be a favorable approach.

Metformin as an Adjuvant Therapy Attenuates Dextran Sulphate Sodium-induced Acute Colitis in Rats

Aims: In numerous cases, patients with inflammatory bowel diseases (IBDs) are refractory to standard treatment. Sirolimus (SIR) and tacrolimus (TAC) are immunosuppressant drugs with encouraging outcomes. However, they have side effects causing limitations in their use. Metformin (MET), which is an antidiabetic drug, has promising anti-inflammatory effects. Thus, this study aimed to validate the effect of the concomitant administration of MET and SIR or TAC in the management of experimentally induced colitis. Study Design: Dextran sulphate (DSS) induced colitis model was used. Methodology: Colitis was induced by administering 5% DSS in water twice daily via oral gavage for 9 days. MET 200 mg/kg alone or in combination with SIR 1 mg/kg or TAC 1 mg/kg was started on day 7 and was continuously administered for 12 days. Then, samples of distal colon tissues were collected for histopathological and immunohistochemistry staining. Then, the pro-inflammatory cytokine, tumour necrosis factor-alpha (TNF-α), interleukin (IL)-1β, IL-6, and IL-17A levels in tissue homogenates were measured. Results: MET, SIR or TAC significantly attenuated the effect of DSS and the levels of all pro-inflammatory cytokines. Moreover, adding MET reinforces the effect of SIR and TAC. Conclusion: MET had a strong anti-inflammatory effect against DSS-induced colitis. Hence, it could be a promising adjuvant therapy in the management of IBDs. The effect was mediated, in part, by inhibiting NF-κB activation. However, the results of this study must be further validated and translated to clinical implications.

Optimizing the Use of Hydroxychloroquine in the Management of COVID-19 Given Its Pharmacological Profile

After the global pandemic of the new coronavirus, its rapid spread and many victims, it is necessary to find an effective vaccine or drugs to overcome it. Most specialists consider that repositioning some medications is the best, fastest and most reliable option for treating patients with the new coronavirus without delay. One of these drugs was an old antimalarial drug, hydroxychloroquine. The current review aimed to explore its potential mechanism, as well as its pharmacokinetics and toxicity, in an attempt to suggest a treatment protocol for its use in treating the COVID-19 virus effectively and safely. This study reviewed the published references on the popular search engines as well as the reference books regarding the pharmacological effects of HCQ. The results of this study suggested the following practical guidelines to optimize HCQ efficacy and safety in the management of COVID-19. HQC should be used as early as possible, i.e., once the viral infection is confirmed or suspected. A loading dose is recommended to be given in 3-4 divided doses to minimize cardiac toxicity. Maintenance daily dose (divided into two doses), should be continued until complete remission. Precautions, drug-interaction, contraindications, variable metabolic pathways in the particular population should be considered. This study suggests more clinical trials regarding the use of HCQ in the management of early identified COVID-19 patients under close medical observation to minimize HCQ cardiac toxicity.  

Colon-Targeted Therapy of Tacrolimus (FK506) in the Treatment of Experimentally Induced Colitis

BACKGROUND/AIMS

Inflammatory bowel disease is a chronic or remitting/relapsing intestinal inflammation, which comprises Crohn's disease and ulcerative colitis (UC). Severe UC is a life-threatening condition that requires corticosteroids (CS) as a first-line rescue therapy. Some patients are refractory to CS and may require alternative immunosuppressive therapy. Oral tacrolimus (FK506), an immunosuppressive agent, has been reported to be effective in the management of severe refractory UC, but it can cause serious adverse effects. This work aims to study the effect of tacrolimus delivered by a colon-targeted delivery system (CTDS) in a dextran sulfate sodium (DSS)-induced animal model of colitis.

MATERIALS AND METHODS

We developed and evaluated an oral CTDS of tacrolimus (FK506) loaded pH-dependent polymeric microspheres, composed of Eudragit® S100 as a pH-sensitive polymer using the oil-in-water emulsion method. The physicochemical properties and drug release profiles of these microparticles in gastrointestinal tract (GIT) conditions were examined. A DSS-induced colitis rat model was used to evaluate the potential remedial and in vivo distribution of microspheres.

RESULTS

The pH-microspheres prevented a burst drug release in acidic pH conditions and showed sustained release at a colonic pH. The in vivo distribution study in the rat GIT demonstrated that pH-microspheres were successfully delivered to the inflamed colon. Moreover, it also demonstrated a significant decrease of disease activity and expression of proinflammatory cytokines, such as tumor necrosis factor α, interleukin-1β (IL-1β), and IL-6, and minimized the histological and morphometric changes.

CONCLUSION

The results confirmed the efficacy of tacrolimus (FK506) CTDs in the management of DSS-induced colitis.

A randomized controlled trial of the safety and efficacy of preoperative rectal misoprostol for prevention of intraoperative and postoperative blood loss at elective cesarean delivery

OBJECTIVE

To assess the safety and efficacy of preoperative rectal misoprostol for the prevention of intraoperative and postoperative blood loss in women undergoing elective cesarean delivery.

METHODS

A single-blind randomized controlled trial of 200 full-term pregnant women scheduled for elective cesarean delivery. Computer-generated randomization allocated women to receive 400 μg rectal misoprostol at urinary catheter insertion plus 400 μg rectally after abdominal closure (preoperative group, n=100) or 800 μg of rectal misoprostol after abdominal closure (postoperative group, n=100). Primary outcome was intraoperative blood loss.

RESULTS

Intraoperative blood loss was significantly lower in the preoperative misoprostol group compared with the postoperative group (528.7 ± 114.8 mL vs 788.6 ± 165.8 mL; P<0.001). Blood loss during the first 24 hours after delivery was also lower in the preoperative group (199.3 ± 84.5 mL vs 302.9 ± 125.6 mL; P<0.001). Fewer women in the preoperative group needed additional uterotonics (7 vs 21; P<0.001). After delivery, the decrease in both hemoglobin and hematocrit levels was significantly less in the preoperative group (-6.8 vs -12.8% and -6.05 vs -17.8%, respectively; P<0.001).

CONCLUSION

Preoperative rectal administration of misoprostol significantly reduced intraoperative and postoperative blood loss during and after elective cesarean delivery. ClinicalTrial.gov ID: NCT03680339. Date of registration 9/2018.

Synthesis and biological activity of new functionalised cyclohepta[4,5]-thieno[2,3-d][1,2,4] triazolo[4,3-a]pyrimidin-5-ones

Various functionalised derivatives of 5 H-cyclohepta[4,5]thieno[2,3- d][1,2,4]triazolo[4,3- a]pyrimidin-5-one were synthesised via reaction of hydrazonoyl halides (1) with either 1,2,3,5,6,7,8,9-octahydro-2-thioxo-4 H-cyclohepta-[4,5]thieno[2,3- d]pyrimidin-4-one (2) or its methylthio derivative (3). The mechanism and the regioselectivity of the studied reactions are investigated and discussed.

Interaction of Cyclosporine A with Pomegranate Juice and Its Potential Nephroprotective Effect in Rats

Objectives: To study the effect of concomitant administering of pomegranate juice orally (PJ) on bioavailability of cyclosporine A (CsA) and independently its potential nephroprotective effect against CsA induced nephrotoxicity. Methods: A- Pharmacokinetic study (PK), Wister rats were divided into groups (each 6 rats) I-: CsA PO + Vehicle; II- CsA IP + Vehicle, III- CsA PO + PJ, IV- CsA IP + PJ. CsA dose was 20 mg/kg for 5 days the vehicle or PJ (2 ml) was given 1 h before drug administration. Blood samples were taken at the 1st and 5th day at specified times and CsA level was determined by immune assays. Relative bioavailability of CsA was determined. B- Nephroprotection study (separate study to administer bioequivalent CsA PO doses, in view of PK study), I- ( CsA 13 mg PO + 2 ml PJ .II- CsA 20 mg P0 + 2 ml vehicle (for 28 day). The design also includes two control groups (vehicle alone or PJ alone). Blood samples for drug analysis, biochemical investigations and kidney samples for histopathology were taken at the 28th day. Results: PJ juice enhanced the bioavailability of oral CsA by about 50% (P > 0.05). But CsA (IP) was not affected after repeated administration for 5 days. Independently, the marked kidney damage induced by CsA was reversed by concomitant administration of PJ as well as it attenuated the increase in serum creatinine. Conclusions: Repeated administration of pomegranate juice enhance CsA oral bioavailability which likely due to inhibition of intestinal enzymes and transport pump. Independently it caused significant attenuation of CsA induced renal toxicity.

From high to low malaria transmission in Zanzibar-challenges and opportunities to achieve elimination

BACKGROUND

Substantial global progress in the control of malaria in recent years has led to increased commitment to its potential elimination. Whether this is possible in high transmission areas of sub-Saharan Africa remains unclear. Zanzibar represents a unique case study of such attempt, where modern tools and strategies for malaria treatment and vector control have been deployed since 2003.

METHODS

We have studied temporal trends of comprehensive malariometric indices in two districts with over 100,000 inhabitants each. The analyses included triangulation of data from annual community-based cross-sectional surveys, health management information systems, vital registry and entomological sentinel surveys.

RESULTS

The interventions, with sustained high-community uptake, were temporally associated with a major malaria decline, most pronounced between 2004 and 2007 and followed by a sustained state of low transmission. In 2015, the Plasmodium falciparum community prevalence of 0.43% (95% CI 0.23-0.73) by microscopy or rapid diagnostic test represented 96% reduction compared with that in 2003. The P. falciparum and P. malariae prevalence by PCR was 1.8% (95% CI 1.3-2.3), and the annual P. falciparum incidence was estimated to 8 infections including 2.8 clinical episodes per 1000 inhabitants. The total parasite load decreased over 1000-fold (99.9%) between 2003 and 2015. The incidence of symptomatic malaria at health facilities decreased by 94% with a trend towards relatively higher incidence in age groups > 5 years, a more pronounced seasonality and with reported travel history to/from Tanzania mainland as a higher risk factor. All-cause mortality among children < 5 years decreased by 72% between 2002 and 2007 mainly following the introduction of artemisinin-based combination therapies whereas the main reduction in malaria incidence followed upon the vector control interventions from 2006. Human biting rates decreased by 98% with a major shift towards outdoor biting by Anopheles arabiensis.

CONCLUSIONS

Zanzibar provides new evidence of the feasibility of reaching uniquely significant and sustainable malaria reduction (pre-elimination) in a previously high endemic region in sub-Saharan Africa. The data highlight constraints of optimistic prognostic modelling studies. New challenges, mainly with outdoor transmission, a large asymptomatic parasite reservoir and imported infections, require novel tools and reoriented strategies to prevent a rebound effect and achieve elimination.

Impact of thymoquinone on cyclosporine A pharmacokinetics and toxicity in rodents

Objectives

Cyclosporine A (CsA) is an immunosupprsant drug used to prevent graft rejection and in the treatment of several autoimmune diseases. Thyomquinone (TQ), a bioactive component of Nigella sativa, has strong antioxidant properties and has been used in prevention of many toxicities, hence its protective effect and pharmacokinetic interactions with CsA was investigated in this study.

Methods

For bioavailability study, the rats were divided into four groups: TQ (PO, 10 mg/kg) was given alone for 7 days, then TQ plus CsA for another 5 days, CsA was given by two routes (po) and (IP) in a dose of 10 mg/kg 1 h after administration of TQ. Blood samples were taken at the 12th day at specified times, CsA level was determined by immune assays. The protective effect of TQ was studied. Blood samples for lab investigations and histopathology were taken at the 28th day.

Key findings

Thyomquinone reduced the bioavailability of oral CsA by around 32% (P &gt; 0.05). However, bioavailability of IP administered CsA was not affected. Chronic administration of CsA increased concentrations of fasting glucose and Cystatin C and produced marked s kidney alteration of parenchyma which was reversed by concomitant administration of TQ.

Conclusions

A potential drug interaction between TQ and CsA, which may reduced its oral bioavailability. Independently TQ caused significant attenuation of CsA induced renal toxicity and diabetogenic effect.

Risk of inferior alveolar nerve injury with coronectomy vs surgical extraction of mandibular third molars-A comparison of two techniques and review of the literature

The removal of mandibular third molar teeth is one of the most common oral surgical procedures. In a significant number of patients, it carries a degree of associated morbidity, including damage to the inferior alveolar nerve (IAN). For this reason, practitioners desire the most up-to-date guidance on the most appropriate technique, informed by the best available evidence that will produce the lowest incidence of iatrogenic complications. The aim of this study was to perform a systematic review comparing the effect of coronectomy vs complete surgical extraction of mandibular third molar teeth on the risk of IAN injury and other complications in adults. Studies were identified through Embase (1980-2016) and Ovid MEDLINE (1946-2016) database searches. Search terms included coronectomy, partial root removal, deliberate vital root retention, odontectomy, surgical removal, surgical extraction, complete tooth extraction and extract. Limits of the study included humans, English language and randomised controlled trials (RCTs). Only RCTs comparing IAN damage associated with surgical extraction of mandibular third molars vs coronectomy were included. From our database searches, we identified two unique RCTs matching the inclusion criteria. Both evaluated patients who had specific radiographic signs of intimate relationships with the IAN. Upon detailed analysis, the studies were noted to exhibit a high risk of bias in many categories, thereby rendering their results inconclusive. Although evidence from two RCTs suggests that coronectomy can reduce the risk of IAN injury compared to surgical removal of high-risk mandibular third molars, the quality of evidence is insufficient to provide definitive conclusions regarding the preferred technique.

Characterization of the Antinociceptive Mechanisms of Khat Extract (Catha edulis) in Mice

This study investigated the antinociceptive mechanisms of khat extract (100, 200, and 400 mg/kg, i.p.) in four pain models: two thermic (hot plate, tail-flick) and two chemical (acetic acid, formalin) models. Male mice were pretreated intraperitoneally (i.p.) with the opioid receptor blocker naloxone (5 mg/kg), the cholinergic antagonist atropine (2 mg/kg), the selective α₁ blocker prazosin (1 mg/kg), the dopamine D₂ antagonist haloperidol (1.5 mg/kg), or the GABA_A receptor antagonist, bicuculline (1 mg/kg) 15 minutes prior to i.p. injection of khat extract (400 mg/kg). Khat extract reduced the nociceptive response of mice in the four pain tests. Naloxone significantly inhibited the antinociceptive effect of khat extract in the hot plate, tail-flick, and the first phase of formalin tests. Bicuculline significantly antagonized the antinociceptive effect of khat extract on the hot plate and tail-flick tests. Haloperidol significantly reversed the antinociceptive effect of khat extract on the tail-flick test and the first phase of formalin test. These results provide strong evidence that the antinociceptive activity of khat extract is mediated via opioidergic, GABAergic, and dopaminergic pathways. The mechanism of the antinociceptive action of khat may be linked to the different types of pain generated in animal models.

Pharmacists' self-perceptions in relation to the 'Advanced Pharmacy Practice Framework'

BACKGROUND

The Australian Pharmacy Practice Framework was developed by the Advanced Pharmacy Practice Steering Committee and endorsed by the Pharmacy Board of Australia in October 2012. The Steering Committee conducted a study that found practice portfolios to be the preferred method to assess and credential Advanced Pharmacy Practitioner, which is currently being piloted by the Australian Pharmacy Council. Credentialing is predicted to open to all pharmacists practising in Australia by November 2015.

OBJECTIVE

To explore how Australian pharmacists self-perceived being advanced in practice and how they related their level of practice to the Australian Advanced Pharmacy Practice Framework.

METHOD

This was an explorative, cross-sectional study with mixed methods analysis. Advanced Pharmacy Practice Framework, a review of the recent explorative study on Advanced Practice conducted by the Advanced Pharmacy Practice Framework Steering Committee and semi-structured interviews (n = 10) were utilized to create, refine and pilot the questionnaire. The questionnaire was advertised across pharmacy-organizational websites via a purposive sampling method. The target population were pharmacists currently registered in Australia.

RESULTS

Seventy-two participants responded to the questionnaire. The participants were mostly female (56.9%) and in the 30-40 age group (26.4%). The pharmacists self-perceived their levels of practice as either entry, transition, consolidation or advanced, with the majority selecting the consolidation level (38.9%). Although nearly half (43.1%) of the participants had not seen the Framework beforehand, they defined Advanced Pharmacy Practice similarly to the definition outlined in the Framework, but also added specialization as a requirement. Pharmacists explained why they were practising at their level of practice, stating that not having more years of practice, lacking experience, or postgraduate/post-registration qualifications, and more involvement and recognition in practice were the main reasons for not considering themselves as an Advanced Pharmacy Practitioner. To be considered advanced by the Framework, pharmacists would need to fulfill at least 70% of the Advanced Practice competency standards at an advanced level. More than half of the pharmacists (64.7%) that self-perceived as being advanced managed to fulfill 70% or more of these Advanced Practice competency standards at the advanced level. However, none of the self-perceived entry level pharmacists managed to match at least 70% of the competencies at the entry level.

CONCLUSION

Participants' self-perception of the term Advanced Practice was similar to the definition in the Advanced Pharmacy Practice Framework. Pharmacists working at an advanced level were largely able to demonstrate and justify their reasons for being advanced practitioners. However, pharmacists practising at the other levels of practice (entry, transition, consolidation) require further guidance regarding their advancement in practice.

Comparison of physical quality assurance between Scanora 3D and 3D Accuitomo 80 dental CT scanners

BACKGROUND

The use of cone beam computed tomography (CBCT) in dentistry has proven to be useful in the diagnosis and treatment planning of several oral and maxillofacial diseases. The quality of the resulting image is dictated by many factors related to the patient, unit, and operator.

MATERIALS AND METHODS

In this work, two dental CBCT units, namely Scanora 3D and 3D Accuitomo 80, were assessed and compared in terms of quantitative effective dose delivered to specific locations in a dosimetry phantom. Resolution and contrast were evaluated in only 3D Accuitomo 80 using special quality assurance phantoms.

RESULTS

Scanora 3D, with less radiation time, showed less dosing values compared to 3D Accuitomo 80 (mean 0.33 mSv, SD±0.16 vs. 0.18 mSv, SD±0.1). Using paired t-test, no significant difference was found in Accuitomo two scan sessions (p>0.05), while it was highly significant in Scanora (p>0.05). The modulation transfer function value (at 2 lp/mm), in both measurements, was found to be 4.4%. The contrast assessment of 3D Accuitomo 80 in the two measurements showed few differences, for example, the grayscale values were the same (SD=0) while the noise level was slightly different (SD=0 and 0.67, respectively).

CONCLUSIONS

The radiation dose values in these two CBCT units are significantly less than those encountered in systemic CT scans. However, the dose seems to be affected more by changing the field of view rather than the voltage or amperage. The low doses were at the expense of the image quality produced, which was still acceptable. Although the spatial resolution and contrast were inferior to the medical images produced in systemic CT units, the present results recommend adopting CBCTs in maxillofacial imaging because of low radiation dose and adequate image quality.

Dilemmas of the causality assessment tools in the diagnosis of adverse drug reactions

Importance: Basic essence of Pharmacovigilance is prevention of ADRs and its precise diagnosis is crucially a primary step, which still remains a challenge among clinicians. Objective: This study is undertaken with the objective to scrutinize and offer a notion of commonly used as well as recently developed methods of causality assessment tools for the diagnosis of adverse drug reactions and discuss their pros and cons. Evidence review: Overall 49 studies were recognized for all assessment methods with five major decisive factors of causality evaluation, all the information regarding reasons allocating causality, the advantages and limitations of the appraisal methods were extracted and scrutinized. Findings: From epidemiological information a past prospect is designed and subsequent possibility merged this background information with a clue in the individual case to crop up with an approximation of causation. Expert judgment is typically based on the decisive factor on which algorithms are based, nevertheless in imprecise manner. The probabilistic methods use the similar principle; however connect probabilities to each measure. Such approaches are quite skeptical and liable to generate cloudy causation results. Causation is quite intricate to ascertain than correlation in Pharmacovigilance due to numerous inherent shortcomings in causality assessment tools. Conclusions and relevance: We suggest that there is a need to develop a high quality assessment tool which can meticulously establish suitable diagnostic criteria for ADRs with universal acceptance to improvise the fundamental aspect of drug safety and evade the impending ADRs with the motive to convert Pharmacovigilance into a state of art.

Appraisal of antimicrobial prescribing practices of governmental and non-governmental dentists for hospitals in the western region of Saudi Arabia

OBJECTIVE

To scrutinize the knowledge, attitude, and antimicrobial practices in Saudi Arabian Dentistry.

METHODS

In this cross-sectional survey of dentists, a self-administered questionnaire comprising of 61 questions was dispersed to the participants randomly, which included their professional profile, awareness of the current scope of antimicrobial resistance, prescribing practice, frequency of antimicrobial prescription, and sources of continuing education of antimicrobials. The study took place in the Faculty of Dentistry, King Abdulaziz University, Jeddah, Kingdom of Saudi Arabia between February and April 2013.

RESULTS

Knowledge and awareness concerning specific antimicrobials, with specific oral cavity lesion was 78% for the students and interns, 80% for residents, and 95.3% for specialists. Approximately 89% of the students, interns and residents, and 98.4% of the specialists endorsed indiscriminate use of antibiotics. In addition, 93.4% of students, 90% of interns and residents, and 90.6% of specialists agreed that lack of health education is one of the contributors to overuse of antimicrobials. Moreover, 91.9% of the interns, 80% of residents, and 75.5% of specialists preferred amoxicillin + clavulanate as their first choice; however, a wide variation in the dosage frequency, and duration was observed.

CONCLUSION

Participants are well aware of the significance of antimicrobial resistance, and considered that judicious use of antimicrobials is highly imperative to restrain this fiery predicament. Divergence was demonstrated between specialists and residents in prescribing practices. Institutional antimicrobial guideline was not interesting to all the respondents. This highlights the need for incessant instructive intervention in order to accomplish the prime objective of retreating antimicrobial resistance.

Pharmacokinetic approach for optimizing gentamicin use in neonates during the first week of life

Introduction:

Gentamicin is an essential drug for the treatment of sepsis in neonates. The current work aims to optimize the use of gentamicin in neonates during the first week of life.

Materials and Methods:

The study was done at King Abdul-Aziz university hospital. Seventy-three neonates who received gentamicin 4-5 mg/kg and dosing interval at 24-48 hr were enrolled. Peak and trough serum levels of gentamicin were determined by immunoassay. Pharmacokinetic parameters were estimated assuming one compartment model and first order elimination kinetic. Analysis of variance was used to test the difference between means using Statistical Package for the Social Sciences (SPSS) Version 13.

Results:

About 73% of the patients attained peak gentamicin level within therapeutic range (6-12μg/ml), while 12% showed potentially toxic trough level (>2 μg /ml). The incidence of trough level was higher among patients receiving the drug every 24 hr. There was no clear correlation between high trough level and serum creatinine. High volume of distribution (Vd) of gentamicin (0.40-0.45) L/kg was observed. Neonates with proven sepsis showed higher mean Vd. Those with extremely low birth weight showed significantly longer half life of 11.5 h. Other neonates showed half life of (8-9) hr.

Conclusions:

Gentamicin dose of 4.5 mg/kg every 36 hr is recommended as simple empirical regimen during the 1^st week of life for neonates with normal or LBW and every 48 hr for those with ELBW.

Expression of microRNAs: potential molecular link between obesity, diabetes and cancer

Clinicians are routinely challenged in their management of cancer patients because of the complexities of obesity and diabetes that are often found as comorbid conditions. Although attention has been given to optimizing treatment planning for these patients, less attention has been given to manage their obesity and diabetes. This suggests that newer, comprehensive approaches must be developed for the treatment of cancer patients as a 'whole' rather than as a single disease. While the specific pathologies of each are unique, years of research have indicated intimate molecular links between these chronic diseases. The contribution of sedentary lifestyles and poor dietary habits is recognized; however, the precise molecular links are still not well-explored. In addition, emerging evidence suggests the important role of microRNAs (miRNAs) in the development and progression of several diseases, yet their roles in linking obesity, diabetes and cancer are only now beginning to be recognized. It is hoped that miRNAs will serve as novel biomarkers and molecular targets for cancer therapy in patients with comorbid conditions. In this review, we discuss the current understanding of the pathobiology of obesity, diabetes and cancer, and document molecular roles of miRNAs linking cancer with obesity and diabetes.
