+	     * Creates a `lodash` object which wraps `value` to enable implicit method
+	     * chain sequences. Methods that operate on and return arrays, collections,
+	     * and functions can be chained together. Methods that retrieve a single value
+	     * or may return a primitive value will automatically end the chain sequence
+	     * and return the unwrapped value. Otherwise, the value must be unwrapped
+	     * with `_#value`.
+	     *
+	     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
+	     * enabled using `_.chain`.
+	     *
+	     * The execution of chained methods is lazy, that is, it's deferred until
+	     * `_#value` is implicitly or explicitly called.
+	     *
+	     * Lazy evaluation allows several methods to support shortcut fusion.
+	     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
+	     * the creation of intermediate arrays and can greatly reduce the number of
+	     * iteratee executions. Sections of a chain sequence qualify for shortcut
+	     * fusion if the section is applied to an array and iteratees accept only
+	     * one argument. The heuristic for whether a section qualifies for shortcut
+	     * fusion is subject to change.
+	     *
+	     * Chaining is supported in custom builds as long as the `_#value` method is
+	     * directly or indirectly included in the build.
+	     *
+	     * In addition to lodash methods, wrappers have `Array` and `String` methods.
+	     *

+	     *
+	     * The wrapper `String` methods are:

+	     * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,

Moderate intra and extrahepatic biliary duct dilatation, more pronounced within the left lobe of the liver. No obstructing lesion is identified. The pancreatic duct remains within normal limits.  There are several indeterminate soft tissue filling defects within the transverse and descending and sigmoid colon.      MRCP (|DATE_TIME|): No convincing ductal calculus seen - likely secondary to previous cholecystectomy.     Ultrasound thyroid (|DATE_TIME|): The left lower lobe demonstrates a 18 x 17 mm nodule in keeping with a U2 nodule. The right lobe demonstrated an upper aspect irregular outlined nodule of 11 x 12 mm with a heterogenous appearance and some peripheral calcific change suggestive of a U4 classification. The thyroid gland was otherwise normal. No abnormal lymph nodes noted.       I had a telephone consultation with |PERSON| today in lieu of his hospital appointment given the current situation with |PERSON|. Overall, it seems as though things remain fairly stable in terms of his Crohn's. He opens his bowels about four times a day and passes fairly loose stool but this has been the case for quite some time. He still complains of abdominal pain around the right lower side of his abdomen. This is as previously described and hasn't changed either.       At the beginning of this year |PERSON| was investigated for weight loss and had a CT chest, abdomen and pelvis which showed no obvious cause for this pain. I have explained this to him today. However, the scan did show some abnormalities which required further investigation (as above). He went on to have an ultrasound of his thyroid which has shown a right sided U4 nodule. I have discussed this with our ENT team who have suggested an urgent FNA and referral to the Head |amp; Neck team which I have organized today.        I have rung |PERSON| again today to explain that this is the case and we need to investigate things further which he is happy for me to do. He tells me that he did have surgery by |PERSON||PERSON| at the |LOCATION| when he was in his 60s but didn't know much else about this. Previous notes suggest he may have had a parotidectomy.        He currently uses a mobility scooter and can manage one flight of stairs but with some difficulty.         We will wait to see what the above shows. Otherwise in terms of his Crohn's, I have asked Mr |PERSON| to hand in a faecal calprotectin so we can monitor this and also have some up-to-date blood test. We will see him again in about eight months' time.

He has been feeling well. He has noticed some discomfort in his right iliac fossa but on further questioning reports that this is longstanding and unchanged. His weight has increased over the last year to 12 stone from 10st and his appetite is good.       I note his most recent faecal calprotectin is elevated at 536. Although he feels well he is currently off all Crohn's treatment following his diagnosis of thyroid malignancy last year. Given the rise in his calprotectin I have discussed his case with |PERSON|  who has suggested a repeat calprotectin in two months. If this is rising then we would need to consider restarting treatment, possibly with vedolizumab as this is more gut-specific immunosuppression.
