Dear Editor, The progression of oral cancer (OC) is usually viewed as an ongoing series of epithelial changes in the oral mucosa1. Due to its advanced locoregional stage at the time of diagnosis, OC ranks as the sixth most often reported malignant disease worldwide, with significant rates of cancer morbidity and mortality. The greatest outcomes for patients come from early discovery and fast treatment, although the preponderance of OC tumours is found in late stages, with a 55% mortality rate. Poor OC results are mostly caused by unavailable or insufficient local screening and surveillance, which leads to delays in expert referrals and possible treatments2. Potential therapeutic conundrums could be alleviated by comprehending the advancements of innovations like artificial intelligence (AI). The use of AI in the treatment of oral malignant tumours can help with the current woes in prognosis prediction and illness diagnostics. AI imitates human cognitive processes, represents an innovation breakthrough and has captured the attention of scientists all around the world. AI system is a framework that analyses information to find designs, trains itself using data and produces outcomes effective outcomes3 (Fig. 1).Figure 1: Workflow of an artificial intelligence model.A pathologist can assess whether a patient has malignancy and the stage of the disease when histopathologic samples are tested for OC. There is occasionally a risk for error because human quantification is necessary for the evaluation of samples for diagnostic features with error invariably resulting in erroneous altercation. As a result, AI has decreased these mistakes and enhanced the effectiveness and precision of recognizing the cytologic and histologic aspects of OC. AI technology can also analyse big sample sizes to find OC. In the studies that were chosen, biopsy and histologic samples as well as photographic pictures were used as samples. Biopsy and histologic samples were used in six research. In several investigations, cellular alterations were used as a marker to distinguish malignant samples from regular and aberrant cell nuclei. Using the suggested segmentation method, examined epithelial alterations by finding keratin pearls in the oral mucosa of patients with OC. With their suggested convolutional neural network (CNN) machine, they quantified the keratinization layer, which was successful because this metric is crucial for diagnosing the stage of OC. For the purpose of detecting OC, we have several deep learning algorithms available. CNN is one such method that might be the most effective at finding OC. A more sophisticated and promising variation of the traditional artificial neural network model is CNN. It is designed to handle more complicated problems, preprocessing and data compilation. It uses the order in which the neurons are arranged in its datasets as a point of reference. The convolutional layer, the pooling layer, the ReLU correction layer and a fully connected layer similar to a multilayer perceptron are the four different types of layers used in this method. Based on the number of outputs, we can estimate the number of neurons, the complexity and whether it is benign or cancerous when you run an magnetic resonance imaging scan over these layers4,5. Radial basis function neural network (RBF) is yet another method to understand the data. An artificial neural network that uses radial basis functions as activation functions is known as an RBF network. A linear combination of the inputs’ radial basis functions and the neuronal parameters makes up the network’s output. These kinds of functions are used for both classification and regression and can take several inputs at once. RBF employs weights and a variety of RBF functions, and we can change the weights and RBF parameters to suit each given case. The Gaussian or normal distribution is the most straightforward to implement among the several functions used to estimate data distribution, as you only need to figure out the mean and standard deviation for the training data (Fig. 2). A large number of additional species may be added, but only related solution vectors may cross over. This module increases the accuracy rate by intensifying the nucleus pixels6,7.Figure 2: Schematic representation of simple multilayer perceptron, radial basis function and convolutional neural network.AI will significantly alter studies on the early diagnosis of OC, and so enhance medical treatment in general. Though AI is in its primitive stage, diagnoses of patients, clinical judgement calls and failure predictions in the dental field can all be successfully performed using AI. It is a trustworthy modality for use in the fields of OC detection along with application in other fields such as periodontics, prosthodontics, orthodontics, forensic dentistry, radiography and oral and maxillofacial surgery as well as restorative dentistry8. AI provides significant prospects for task automation by detecting complicated patterns. In this regard, research is critical to facilitating the multidisciplinary adoption of such methodologies, and advancements in this area could pave the way for future investigations9. Early identification is crucial for patients with OC because the disease’s prognosis is dismal in its late stages. Using the information from cytology images, fluorescence images, computed tomography images and depth of invasion, OC can be diagnosed more rapidly and accurately. On the basis of the risk classification model, 11 981 prepossessed pictures were loaded for AI analysis to evaluate the effectiveness of AI with traditional cytology and histology and the results indicated a diagnostic accuracy of 80–84%3. Machine learning produces reliable outcomes for identifying OC, which is beneficial for pathologists to enhance their diagnostic outcomes and reduce the possibility of error. Furthermore, deep learning (neural networks), which denotes superior efficiency and hence is more accurate, has been employed in the research that were considered the best based on the data. It is evident that when compared with traditional methods of diagnosis, AI is more accurate in diagnosing OC. Using reliable data from AI, patients can be categorized as high risk or low risk, assisting physicians in diagnosis and treatment of OC. Ethical approval None. Sources of funding None.

Dear Editor, Malnutrition has been defined as a subacute or chronic nutritional condition characterized by a decrease in muscle mass, fat mass and function, including immunological function, brain ability and muscular endurance1. Severe weight loss, a sign of subacute malnutrition, ranges from 20 to 50% in the pre treatment phase for head and neck cancer (HENC)2,3. Malnutrition in HENC patients might have a variety of reasons. A primary cause of malnutrition before therapy is limited food intake, which is caused by mechanical blockage of food or discomfort induced by the tumour. Cachexia, a complicated metabolic state linked with underlying disease and characterized by muscle loss with or without fat mass, may also contribute to malnutrition during this time period4. Malnutrition may develop or worsen during and after treatment as a result of treatment-related oral symptoms such as chewing and swallowing difficulties, discomfort, dry mouth, sticky saliva and taste alterations5. Increased inflammatory activity, such as that caused by radiation-induced mucositis, may potentially be responsible for malnutrition during this phase6. HIGHLIGHTS Malnutrition is described as chronic nutritional disorder indicated by a loss of muscle mass. Cachexia contributes to malnutrition in HENC patients receiving treatment. Swallowing difficulty and oral pain are pre-treatment risk factors for malnutrition in HENC patients. Although malnutrition is widely observed before HENC therapy, statistics on the prevalence of malnutrition following treatment for oropharyngeal cancer are limited. This number increased to 24% when patients got food guidance during and immediately after radiation. Malnutrition was seen in 27 and 6% of HENC patients who received tube feeding during and after radiation, respectively, in the third and sixth months following the commencement of radiotherapy7,8. Other research on malnutrition in HENC patients has focused on nutritional status changes during and after therapy. In a randomized controlled trial on HENC patients treated with radiotherapy, nutritional status worsened 3 months after treatment in all patients who did not receive dietary counselling or dietary supplements, but this frequency was limited to 12% when patients received dietary counselling during radiation therapy. Mean body weight reduced considerably in HENC patients who did not get dietary guidance during and after therapy, to 2.3 kg during treatment and 2.2 kg after treatment9. In all of these investigations, the prevalence of malnutrition decreased in patients who received nutritional intervention within the first 6 months of therapy10. Oral symptoms are widely established risk indicators for malnutrition. Swallowing problems and mouth discomfort were found as key risk factors for malnutrition in HENC patients during the pretreatment phase5. In addition to swallowing difficulties, individuals undergoing treatment for oropharyngeal cancer may experience chewing difficulties as a result of poor dental health or trismus11. Due to radiation-induced mucositis, oral oedema, sensitive oral mucosal surfaces, surgically induced anatomical or temporal changes required to insert a new one to make a prosthesis, edentulous patients are frequently unable to wear their prosthesis for about 3 months after surgery and, in some cases, up to 6 months after radiation or chemotherapy12. Furthermore, trismus can be caused by scar tissue development as a result of surgery or radiation therapy. The link between poor dental health, trismus and malnutrition in individuals with oropharyngeal cancer has never been examined. As a result, it is unclear which oral symptoms are risk factors for malnutrition following therapy for oropharyngeal cancer. Malnutrition is more likely to result from swallowing issues during therapy and, to a lesser extent, after treatment. Researchers should advocate medical examination for swallowing issues and malnutrition in patients after treatment for oropharyngeal cancer to limit the risk of post-treatment malnutrition related to swallowing problems. Thorough investigations should look at whether measures to overcome swallowing issues can minimize or perhaps prevent the occurrence of post-treatment malnutrition. For instance, the nutritionist and speech therapist should jointly evaluate the supposed success of collaborative therapy for treatment-related swallowing issues. Furthermore, while large randomized controlled studies on this topic are currently missing, the role of early tube feeding, for example, through prophylactic gastrostomy insertion, is being investigated. It is now evident that early post-treatment malnutrition is a serious issue in individuals with oropharyngeal cancer. Only swallowing difficulties were strongly related to malnutrition in the interval following oropharyngeal cancer therapy. Ethical approval Not applicable. Sources of funding None.

Arenaviruses are segmented negative-sense RNA (nsRNA) viruses that are closely related to those of the Bunyaviridae and Orthomyxoviridae families. The Lassa Virus (LASV), the agent of Lassa illness, is a member of the family Arenaviridae. LASV was first identified in 1969 by a missionary nurse working at a clinic in a small community named Lassa in northern Nigeria. She had likely got contact with the virus from a LASSA-based infection of an obstetrical patient and had died within a week following the onset of her symptoms1. One of the nurses who had treated the first patient also contracted what would later become Lassa fever and died. It is estimated that between 100 000 and 300 000 people were infected with LASV annually, leading to roughly 5000 deaths. The reservoir rodent, Mastomys natalensis, may be found all over West Africa and is responsible for the spread of the LASV. Human infections have been confirmed through serology in the countries of Senegal, Guinea, Sierra Leone, Liberia, and Nigeria (Figs. 1 and 2). From the late 1970s until the early 1990s, eastern Sierra Leone was host to the sole long-term investigation of Lassa disease in all of West Africa. After repeated requests from the government of Sierra Leone to research epidemics in the eastern province, the Centers for Disease Control and Prevention (CDC) developed and funded the project2.Figure 1: Lassa fever recorded cases from 1969 to 2022.Figure 2: Spread of LASSA Fever 1969–2022.The clinical presentation, epidemiology, immunology, pathophysiology, and treatment of Lassa fever have all been elucidated throughout the years. Not only have war and social unrest over the past decade hampered ongoing research and prevented new ones from taking place, but they have also likely contributed to a rise in disease rates in these places. Between 7 and 21 days is the incubation period for Lassa fever3. The initial stages of the clinical sickness are similar to the flu, including high fever, overall weakness and overall lethargy, sore throat, cough, and severe headache. Nausea, vomiting, and diarrhea are among the common gastrointestinal symptoms that may appear early on. Despite the absence of major hemorrhagic signs, vascular dysfunction is believed to be an important part of the pathobiology of Lassa fever given its association with a dismal prognosis4. Facial edema, pleural effusions, and pericardial effusions are all symptoms of a vascular permeability problem5. Lassa fever patients typically begin to feel better 8–10 days after becoming unwell6. In extreme cases, between the 6th and 10th day of the sickness, the patient’s health rapidly deteriorates with significant pulmonary edema, acute respiratory distress, encephalopathy signs, and fatal shock. Despite being common, mucosal surface bleeding seldom causes shock. sensorineural deafness is common in severe disease or early recovery7. Arenaviridae virus Lassa is encapsulated, single-stranded, bi-segmented RNA. LASV, like other arenaviruses, lacks negative-strand coding and the virus isolates varied genetically, serologically, and pathologically. LASV is spherical and 70–150 nm wide, glycoprotein-built T-shaped spikes measure 7–10 nm on its smooth surface envelope. The single-stranded arenavirus genome has two RNA fragments, respectively. The sRNA encodes the viral glycoprotein precursor protein (GPC) and nucleoprotein (NP), while the lRNA encodes the viral polymerase and a tiny, zinc-binding (Z) protein28. New full-length sRNA amplification methods aid arenavirus identification and molecular analysis29. LASV sRNA sequencing identified and molecularly characterized four strains. Sequencing of LASV sRNA showed a lot of genomic diversity1. It can be speculated from the available data (data acquired from the CDC) that the spread of LASSA is unusual and mostly in the first six months of the year (Table 1)8. According to the climatology reports9, the temperature between December to June is 26.9–31⁰C. The temperature could be a factor; however, more research should be done to better understand this. Virus isolation is the best LASV diagnostic method, but BSL-4 biocontainment makes it unfeasible in endemic areas. ELISA or RT-PCR are the most frequent methods for detecting viral proteins or LASV-specific IgM or IgG antibodies. The immunofluorescence assay (IFA) was utilized to detect LASV antibodies; however, it required BSL-4 biocontainment, highly trained workers, and low sensitivity. Clinical and laboratory use persists. In an orthogonal diagnostic system, PCR-based molecular assays like RT-PCR give the most confidence in results10. Due to the genetic heterogeneity in LASV strains throughout a wide geographic area, primer and probe failures are more likely in PCR-based experiments. Most assays target the short RNA that encodes the GPC precursor and NP. Because LASV-specific IgG is produced later in the infection, this assay is limited in patient diagnosis11. LASV diagnostics should be simple, robust, sensitive, and affordable, considering LASV lineage genetic and geographical variability. Diagnostic advances in LASSA fever will improve treatment, control, and prevention in endemic areas. Point-of-care immunological and/or PCR-based assay equipment will soon bring diagnostics to patients to improve treatment decisions and patient outcomes. LASV antibody frequency in known and potential endemic places will improve risk maps. Metagenomics in outbreaks and rodent reservoir hosts will enhance LASV eco-epidemiology the most. This method could answer issues about LASV incidence, transmission bottlenecks, and reservoir host virus variety. Our defense against emerging and re-emerging viruses like LASV will involve a better understanding of the virus circulating in the environment, sickness in humans, and virus maintenance in rodent reservoir hosts. Diagnostics are best for LASSA fever prevention today and in the future. Table 1 - Places of origin and places where it spread between 1969 and 2022.

This publication acts as both a catalyst and a call to action for future research into the role that the virus plays in the development of tumors. On the other hand, a number of studies have found evidence that the virus inhibits the growth of cancerous cells. For example, the Lassa-vesicular stomatitis chimeric virus is able to successfully eradicate brain tumors without causing any harm. In point of fact, the expressional pathway analysis indicated a common link between the pathogenesis of Lassa fever and carcinogenesis. Furthermore, it has been established that the anticancer treatment is efficient in preventing the entry of the LASV into cells14. Due to this, additional study in clinical medicine is still required in order to understand the precise nature of the relationship between the LASV and the tumor.

Carbapenems are a class of antibiotics that are effective against a wide variety of bacteria because of their distinctive structure, which consists of a carbapenem coupled to β-lactam ring that provides resistance to most lactamases, including metallo-lactamase (MBL) and extended-spectrum-lactamases. Furthermore, carbapenems are among the most effective medications used to treat bacterial infections1. Acinetobacter baumannii is now recognized as a significant threat to many facilities worldwide. Its enormous capacity to acquire or upregulate antibiotic drug resistance determinants has deservedly catapulted it to the forefront of scientific interest .Infections caused by A. baumannii are a common source of complications for patients in the ICU2. A. baumannii healthcare-associated infections (HAIs) have been linked to an elevated risk of mortality ranging from 8 to 40%. A. baumannii's exceptional capacity to gain resistance to several antibiotics, together with the pathogen's remarkable ability to survive for an extended period of time, are causes for serious concern. Although A. baumannii is most commonly found in ICUs, it has lately been linked to a wide variety of infectious diseases in military troops and organ transplantation3,4. As of late, it has come to light that A. baumannii possesses outer membrane proteins (OMPs) that contribute to its carbapenem resistance. Clinical isolates of A. baumannii lacked detectable carbapenemase activity, and this resistance to imipenem was linked to the loss of a 29 kDa OMP. It has been shown that the loss of a heat-modifiable 29 kDa OMP, dubbed CarO (an A. baumannii OMP involved in carbapenem resistance), is linked to resistance to imipenem and meropenem in multidrug-resistant A. baumannii clinical isolates. Cloning and characterization of the chromosomal region encoding CarO in clinical isolates revealed that the A. baumannii genome contains just a single copy of CarO, which is organized into a single transcriptional unit. The polypeptide encoded by the CarO gene consists of 247 amino acid residues and has a canonical N-terminal signal sequence as well as a predicted transmembrane barrel structure. CarO was disrupted by unique insertion elements in carbapenem-resistant clinical isolates of A. baumannii, lending credence to the idea that CarO plays a role in the uptake of carbapenem drugs by A. baumannii5. Studies highlight another obstacle that bacteria's mobile elements present to efforts to curb the spread of antibiotic resistance. Only the OprD of Pseudomonas aeruginosa, another nonfermentative pathogen belonging to the family Pseudomonadaceae of the class Proteobacteria, has been characterized to date as a specialized OM channel for carbapenems6. OprD is involved in the uptake of specific peptides and basic amino acids, and mutations that render OprD nonfunctional are a common cause of carbapenem resistance in clinical P. aeruginosa strains. But A. baumannii CarO is significantly smaller and has no conserved primary sequence homology to P. aeruginosa OprD. Furthermore, immunoblot analysis of the OMP fractions of various A. baumannii strains using an antiserum directed against P. aeruginosa OprD and the absence of OprD homologs in the recently released genome of Acinetobacter spp. strain ADP1 suggest that OMPs whose sequences are related to OprD are seemingly absent in Acinetobacter spp. (GenBank accession number CR543861)7. As a result, CarO may behave as an OprD analog in A. baumannii, allowing the pathogen to take up carbapenems. The physiological roles of this protein in A. baumannii are being investigated, as is the possibility that CarO achieves its function via forming complexes with other OMPs8. Finally, the hypothesized mechanism of carbapenem resistance may be limited in its general diffusion because CarO homolog genes appear to be limited to a specific family of the class Proteobacteria, the Moraxellaceae. In fact, many members of this family are recognized or suspected carcinogens The unsettling likelihood that they could eventually evolve carbapenem resistance via a similar mechanism calls for more awareness and research4. In conclusion, the emergence and spread of antibiotic resistance can be halted through the following steps: reasoned utilization antibiotics in all configurations; execution of infection control measures in hospital environments; creation of strategies to reduce the risks of exposure; advancement of rapid diagnostic tests; initiatives of research on antibacterial resistance preventative measures and surveillance; and advancement of research on novel antibiotics (Fig. 1). Concerningly, A. baumannii tends to grow in clonal fashion within institutions or cities, making its worldwide epidemiology a cause for alarm. There is undeniably a need for novel medicines, and as doctors, microbiologists, and scientists, we must take a holistic approach to the creation of effective new antimicrobial drugs. To convince the public and policymakers of the medical and economic benefits of addressing the danger of antimicrobial resistance, a worldwide and coordinated approach is required.Figure 1: Proper interventions in carbapenem-resistant Acinetobacter baumannii control.Ethical Approval and the relevant judgment's reference number Not applicable.

Dear Editor, Every day, millions of new cancer cases are recorded, suggesting that the disease is increasingly threatening people all over the world. This deadly disease is projected to increase in prevalence by a factor of five. The Knudson two-hit hypothesis proposes that the inherent mutation serves as the first hit to a gene, with a subsequent event serving as the second hit that causes cancer to develop. Many cases begin with the development of precancerous diseases. All clinical manifestations that carry the risk of cancer, including syndromes linked with a higher-than-normal risk of malignant transformation, are collectively referred to as 'oral potentially malignant disorders'1. Bloom syndrome (BS), often called Bloom-Torre-Machacek syndrome after the researchers who discovered it, is one such oral potentially malignant disorders. People of European Jewish descent are adversely impacted from BS. The primary clinical hallmark of BS is short stature, and it is transmitted in an extremely rare autosomal recessive pattern2. The presence of a sun-sensitive, erythematous lesion on the face, an abundance of well-demarcated hyperpigmented and hypopigmented skin lesions anywhere on the body, and an increase in the number of bacterial infections related to immunodeficiency are all helpful diagnostic markers. Cancer, chronic lung disease and diabetes are some of the severe consequences of BS. Cancers of the normal forms and locations appear at unusually high and early rates. Many of the symptoms of BS result from the hypermutability of the cells that comprise the condition. Patients with BS are prone to the same types of cancers as the general population, but they tend to manifest considerably earlier in life. The current BS population has a mean age of 18 years (range: 4–37 years). In the BS population, cancer often presents at age 20 years (range: 4–44 years), with a proportion of 1:40 men to every woman, making men more susceptible to BS. Ashkenazi Jews, non-Jewish Semites, Japanese, Western European Christians and African-Americans are few of the ethnic groups and races that have been shown to have BS. More than one in every 120 Israeli Ashkenazi's is a carrier of at least one allele of the heritable disease. Cytogenetic evidence of a signature kind of chromosomal instability confirms the clinical diagnosis3. Cancer was the cause of death for every person with BS who made it past childhood. Tongue and laryngeal carcinoma were among the primary lesions found in five of the first 103 BS patients. There were smokers and nonsmokers, Jews and non-Jews and people of all ages (from 26 to 34 years) from the USA, Canada and Australia who participated in the study. The male population was four times that of the female population. The most striking distinction from non-BS patients was the young age of onset of the disease, as the presenting symptoms and tumour histology were identical. Two BS patients with second primary tumours showed the importance of careful postoperative monitoring for the development of secondary tumours anywhere in the body, not just the head and neck. Having a computed tomography scan periodically and having regular physical examinations are both necessary4. Researchers studied the frequency of micronuclei in exfoliated epithelial cells in two small human populations: those homozygous and heterozygous for the Bloom syndrome gene (BML). They analysed 11 obligate heterozygotes (BML/+), including the parents of affected individuals, and eight homozygotes (BML/BML) for the BS gene, that is, people with the clinical condition5. Oral and urinary exfoliated cells were collected. Statistically substantial increases in the frequency of cells with micronuclei were seen in cells from both sites in BML/BML persons compared with that in BML/+ (P<0.001) and in a control group, showing that chromosome instability occurs in vivo in BS. However, there was no statistically significant difference in the frequency of micronuclei between BML/+ and the control group at either site. In light of the results of this study and comparable earlier studies of populations at risk for malignancy not due to inherited susceptibility but due to interaction to an environmental carcinogen, it seems likely that the exfoliated cell micronucleus test can identify people whose somatic genetic material has been disrupted in a way that generates chromosome breakage and rearrangement5. Cancer is more likely to develop in people with BS at a younger age. Head and neck cancers account for 18% of all neoplasms found in BS patients, with most cases appearing in patients' 30s and 40s. The head and neck cancer rate has tripled in the last few decades, which may indicate a genetic vulnerability to the disease. Chromosomal analysis is the gold standard for diagnosing BS. When it comes to head and neck cancer, individuals with BS and those without have the same surgical options. However, because of the higher risk of a second primary tumour developing, postoperative monitoring must be considerably more stringent in the BS patient. As with many other extremely rare genetic diseases, the entire scope of health effects for people with BS is not well understood. The BS Registry aims to address this issue by the systematic investigation of issues like immunosuppression, lung complications, cognitive decline and cancer pathogenesis and treatment. The tiny number of heterozygotes in any group makes it difficult to adequately power evaluations of risk, however, research into health issues among heterozygotes, especially cancer risk, is a topic for further exploration. To further understand how BML may contribute to the aetiology of cancers in those who are neither affected with BS nor heterozygous for BML pathogenic mutations, research into the genomic abnormalities of tumours arising in people with BS is urgently needed. Although finding medicines that can restore some function of the BML protein is the ultimate objective, none have been found yet6. Newborns and infants with BS need to have their caloric intake and nutritional status closely monitored, and they should receive aggressive treatment for gastroesophageal reflux if it is present. The BS community recommends that parents and educators treat children as they would any other child, regardless of their physical stature. Diabetes mellitus care is standard procedure. Standard cancer treatment protocols must be adjusted, that is, dosages and duration must be lowered, for patients with hypersensitivity to DNA-damaging agents and ionizing radiation. Colon cancer screening begins at a much earlier age and is performed more frequently than average, and surveillance includes reviewing unexplained signs and symptoms as potential signals of malignancy. Keep your face out of the sun7. In the meanwhile, it is crucial for parents and doctors to be aware of the unique health issues faced by people with BS and to take swift action at the first sign of trouble. By paying close attention to these health monitoring metrics, we may perhaps standardize assessment of the patient, which will aid in preventive medicine, diagnosis and treatment and improved healthcare outcomes overall.
